day seven of @bnhaomegaverseweek​ (hoping my love will keep you up tonight) 

Their lips meet in a sloppy kiss Izuku would deny ever liking. It would ruin his reputation as a hopeless romantic if people knew he could be reduced to putty in someone's hands by the sloppiest kiss in existence.

Strong hands grip his hair and tug on the strands hard enough to make him wince, mouth falling open to make a noise of protest. Izuku realizes just then how easily he fell for Katsuki's trap when the omega's tongue sweeps into his mouth, unfalteringly in its movements.

Izuku whimpers as Katsuki takes charge, the omega not giving him the chance to hesitate or second guess what they are doing. He had no illusions about what sex with Katsuki would be like and he relaxes as the omega continues to kiss him.

Katsuki had asked him to come over to his place a few days ago and Izuku had practically had a heart attack, thinking of all the reasons why he would be wanted there. As soon as he had stepped through the door though, he was assaulted by the smell of dinner and had gradually relaxed until they made their way to the couch afterward, Katsuki immediately climbing into his lap to kiss him. From there, Izuku had done his best to leave until Katsuki ground his ass back on Izuku's half-hard cock and dragged him to the bedroom when Izuku couldn't deny his wants anymore. Now Katsuki's hands are buried in his hair, but there is no more tugging or pulling and Izuku settles himself into the motions.

Katsuki starts to move backward then, stopping for just a moment to turn them around and push Izuku back before he can blink. He bounces as he lands on Katsuki's bed, pushing himself up on his elbows as Katsuki pulls his shirt off then undoes his jeans and kicks them off. Izuku only watches him, feeling his cock twitch in his own jeans as Katsuki slides his briefs off and his dick springs free.

He never thought he would find a dick pretty, but Izuku should have known better. Katsuki has always been able to make Izuku see something in a different light, especially whenever it concerns him specifically.

Like quirks. Izuku had been mildly interested in them when he was a toddler, but after Katuski got his quirk, Izuku went absolutely buck wild over them. He wanted to learn everything he could about the different possibilities for quirks and came up with ways for Katsuki to use his own. Izuku wanted to provide all the information that his friend would ever want or need about them and how best to utilize his own so he could become the great hero they both knew Katsuki would be.

(But then Izuku learned he was quirkless and Katsuki slowly stopped talking to him altogether after that. He didn't bully him as the others did, but he did nothing to stop it like Izuku always foolishly hoped he would.)

Like sub genders. In middle school, Katuski had presented as an omega, surprising everyone. Izuku watched as his old best friend fell out of the social hierarchy after news about his presentation spread far and wide. Beforehand, Izuku didn't honestly care about what his own sub gender would be, but after Katsuki presented, Izuku began to hope that he would present too. Maybe then Katsuki would start talking to him whether as a potential alpha mate or a fellow omega friend.

(He did, but only because Izuku never presented and now they were both social outcasts. At least they were together again.)

And now about dicks too, he guesses. In all fairness, Katsuki really does have a pretty dick though. The head is a flushed red - what Izuku can see of it anyway. It's already leaking a little bit of pre-come too and it twitches when Katsuki realizes that Izuku's gaze is stuck on his cock. Katsuki's dick is slim, of average length, and curves slightly to the side, but it is erect and obvious proof of the omega's want.

Izuku gulps as he looks up to meet Katsuki's gaze and has just enough time to spread his thighs before the blonde falls on top of him. Katsuki grips his T-shirt with two fists twisted into the front and Izuku feels his dick jump as the omega rips it apart, the black pieces of cloth sliding off his chest with ease after that. Izuku can practically smell the smugness in Katsuki's scent as he rips Izuku's jeans and underwear off as well, throwing the tattered remains of his clothing to the side.

His cock is now out in the open and leaking pitifully as Katsuki kisses him again. Hands grips his waist as the omega pushes him down onto the mattress, lifting his legs until they fall over Katsuki's hips. Izuku startles for a moment before he spreads his legs wider, not put off in the least as he thinks of Katsuki pushing into him and fucking him open.

Which is why he is very surprised when Katsuki pulls back from their kiss and growls, "Gonna let you fuck me so hard, I turn you into an alpha, fucking shitnerd."

Izuku blinks up at him, bewildered, but there is something about Katsuki's words. He can't quite pinpoint it, but he feels a tingly sensation in the pit of his gut. His heartbeat quickens in his chest and he flushes when he realizes that Katsuki can hear it if the smug grin on his face is anything to go by.

Katsuki drags his tongue down Izuku's throat as he thinks over the words.

When a Beta is accepted by their true mate, their sub gender changes. Their nature twists and shifts until it is of the utmost compatibility with their true mate. Izuku has known two other betas who were accepted by their true mates and had their sub genders change. One an omega and the other an alpha. It isn't uncommon, at least that's what Izuku has gleaned from the countless studies he took an interest in after Todoroki became an omega for Iida.

What Katsuki just said, it must mean that he wants Izuku to be his true mate. That or Izuku already is and his weaker senses are the only reason he had not noticed before.

He gasps for breath as Katsuki drifts lower and takes his nipple between his teeth, biting down hard enough to make Izuku's toes curl. Izuku can feel the soft drag of Katsuki's cock on his thigh as he spreads his legs wider, head thrown back on the bed as Katsuki gives his chest no mercy.

"K-Kacchan!" Izuku yelps when the omega pinches Izuku's other nipple between his deft fingers.

Katsuki pulls back to look at his work, smirking to himself at the sight of Izuku wrecked beneath him. "You're gonna knot me and Claim me tonight, Deku. I've waited long enough, you fucking idiot."

Izuku bites his lip. "Kacchan, why didn't you say anything sooner?"

"I thought you already knew," Katsuki sniffs, adjusting himself until his cock is lying alongside Izuku's. "After fucking Half-and-Half changed and you started talking about all those stupid studies and shit, I thought that you would figure it out."

Katsuki shakes his head then, a tiny genuine smile starting to spread across his lips. "Took Shitty Hair and fucking Pikachu telling me about how you had no clue for me to realize how much of an idiot you actually are. So that's why I invited you over now instead of during my heat. I don't want to end up being wrong and be stuck with a fucking Beta giving me no relief."

Izuku frowns, sure that he should feel a little offended at that last part but mostly just confused. "Kacchan, seriously?"

"Shut up," Katsuki barks back as he wraps his hand around their cocks. "I'm gonna turn you into my own bitch Alpha and then you're gonna Claim me. I deserve only the best, Deku."

"Of course, Kacchan," Izuku murmurs, hips straining as Katsuki begins to pump them. "Only the best for my omega."

Katsuki's grin sharpens then. "That's what I'm fucking talking about."

Izuku laughs, the sound coming out strangled as Katsuki squeezes his dick. "Ah, Kacchan. Be nice, please. I'm really, um... sensitive."

"Shut the fuck up, Deku," Katsuki snaps, but his grip loosens considerably and Izuku stops squirming. "Pass me the lube, it's under that pillow."

Izuku reaches out towards the pillow Katsuki jerked his head toward and scrambles for the plastic cylinder he can vaguely see underneath. He manages to wrap his hand around it and pulls it back towards them, popping open the cap when Katsuki raises an unimpressed brow at him. Katsuki holds his hand out, fingers pressed together tightly and Izuku takes that as a sign to squirt the lubricant on his fingers.

Katsuki rubs the lube between his fingers, blowing on it so its warm and then reaches behind him and let outs a heavy breath as he pushes a finger into him. Izuku can only manage to watch, eyes roaming over Katsuki's sweaty skin and the blonde tendrils of his hair that stick to his forehead.

He inhales deeply and freezes when he realizes that Katsuki's scent is a lot more stronger than it ever has been before. For the first time, Izuku can make out a spiciness to Katsuki's smell that he never caught a whiff of before. He still smells like vanilla and smoke, but now the smell burns as Izuku breathes it in, inhaling deeply again and again until he is sure that he won't forget how his omega smells like anytime soon.

Katsuki keens as he presses another finger into himself, throat exposed as he lifts his chin up into the air, thighs shaking underneath Izuku's own. Izuku opens the bottle of lube and dribbles a small amount onto his palm before he reaches down and wraps his hand around Katsuki's cock. His omega looks down at him in surprise, face flushed a light pink as he works himself open. Izuku manages a smile at him as he starts to move his hand, keeping his movements slow and steady so as to not throw Katsuki off rhythm or push him to the edge too soon.

Izuku keeps eye contact with Katsuki as he strokes him, watching the myriad of emotions that flicker across his omega's face. His chest rumbles with a growl he has never managed to make before and Katsuki grins at him in response, bright delight clear on his face.

"So pretty, Kacchan," Izuku murmurs at him, feeling the blood in his veins race. "Always been so beautiful."

Katsuki scoffs, the sound quieter than usual. "Liar."

"I'm not lying," Izuku assures him, eyes unable to look away from Katsuki's own. "I've always wanted you for my own, Kacchan. I just didn't think you wanted me."

"You're a fucking idiot if you really think I didn't want you too," Katsuki scowls, leaning down and moaning right in Izuku's face. "Never wanted anyone but you to fuck me so hard I can't think straight."

Izuku feels the words go straight to his cock, another growl ripping itself from his chest. "Have you fucked anyone, Kacchan?"

Katsuki's scowl morphs into a frown then, the squelching noises Izuku can no longer ignore growing louder behind Katsuki. "Fuck no. You'll be my first, fucking idiot. As if I'd let some fucking extra have me."

"Good," Izuku hums, feeling something deep within him calm at Katsuki's words. "Only mine."

"Yeah, yeah," Katsuki waves his free hand, pulling his other hand out of him soon after. "Now fuck me, Deku. I'm ready."

Izuku lets go of Katsuki's cock and flips them over so Katsuki is now flat on his back, legs already thrown over Izuku's waist. Katsuki smirks up at him, his arms laid out at his sides and legs spread wide.

"Fuck me so hard you knot me, Deku, otherwise I'm not letting you come," Katsuki challenges him.

"Condom?" Izuku asks instead, ignoring the bristling feeling in his chest that wants to pin Katsuki down and punish him for the taunt.

Katsuki grins at him like he just cracked a particularly funny joke. "Raw me, motherfucker. We're both clean and you know I can't get pregnant even while being an omega, Deku. Just get the fuck on with it already. I'm not getting any fucking younger."

Izuku can't help the growl that rumbles out of him then or how he grips Katsuki's waist hard and pushes into him without waiting for anything else. Katsuki gasps under him, eyes fluttering closed as his hands come up to clutch at Izuku's shoulders. His omega breathes out deeply, biting his lip as his face twists with what Izuku thinks might be from pain.

He panics, already moving to pull out and freezing when Katsuki yells at him, his fiery eyes pinning Izuku in place. "If you pull your dick out of me, I will fucking kill you!"

"Bu-But, Kacchan, y-you-" Izuku starts to stutter.

"Just give me a fucking moment, idiot. You're big," Katsuki mutters, focusing on his breathing as his eyes close again.

Izuku twitches, flushing with pride at the nonchalant compliment. He wants to move, wants to fuck into Katsuki so hard he will only ever think of Izuku ever again, but he keeps still. He doesn't want to hurt his omega, something in him feels like crying just at the mere thought.

"Okay," Katsuki murmurs after a few minutes have passed. "You can move now, shitface."

Izuku nods fervently. "I'll go slow. I don't want to hurt you, Kacchan."

"Don't you start fucking crying," Katsuki spits out, pulling Izuku closer until their noses are almost touching. "Just fucking move already."

Izuku kisses his omega as his hips cant back then push forward, keeping a slow and steady rhythm. Katsuki wraps his arms around Izuku's neck and his legs around his back, keeping him in place. The squelching sounds that ring in the air around them are enough encouragement for Izuku to increase his pace bit by tiny bit. His omega doesn't complain, more than content to kiss him as Izuku takes his time.

Hands bury themselves in his hair and Izuku groans as Katsuki pulls on his dark, curls. Izuku hikes up Katsuki's legs and pushes into him easily, sighing into his open mouth at the pleasant sensation that follows. Katsuki moans underneath him, breaths coming in heavy pants as Izuku's thrusts increase in speed and strength.

"Fuck me," Katsuki whispers between them when Izuku keeps up his maddingly steady pace. "Fuck me so hard you pop a knot, Deku."

Izuku growls, pushing himself upwards as he holds Katsuki open and fucks him just like his omega asked. He cannot explain what urged him to do so, but the sounds Katsuki makes in response are definitely worth it. Izuku doesn't even pause when his cock starts to swell either, he just keeps moving, keeps fucking his omega exactly how he likes it.

Katsuki moans and twists under him. "Knew you could fucking do it, Deku."

"What?" Izuku pants.

"I can feel your knot, Alpha," Katsuki taunts. "Knot me, Alpha. Fill me up."

Something instinctual in Izuku responds before he can verbally. He stops and twists Katsuki around until the omega is on his hands and knees, ass held out like a present. Katsuki groans at the loss of his cock when he first pulls out then sighs as Izuku slides back into him smoothly, the new alpha's eyes trained to the spot where he is buried deep within his omega.

"Bet you wish you could have my pups, Kacchan," Izuku finds himself mumbling as he fucks into his omega with vigor. "Want me to pump you full of them, huh?"

Katsuki's answer is muffled by the bedsheets, but he squirms in excitement so Izuku knows he's into this. Izuku continues to watch his cock being swallowed whole by the omega he has been chasing almost this entire life. His heart beats steadily in his chest as his senses come into bloom, expanding until all he can feel is Katsuki.

"Don't worry, Kacchan. I'll knot you and make you mine, fuck you however you want until you're heavy with my pups and then fuck you again just to be sure," Izuku mutters. "How long have you wanted my knot, Omega?"

Katsuki turns his face to the side, one ruby eye trained on Izuku's face. "Since my first heat. Just wanted you to come into my room and fuck me so hard until I turned you into my knot bitch that I could have whenever I wanted."

Izuku laughs, feeling himself return to his senses. "Well, you did just that, Omega. Bet you can't wait until your next heat so you can use me however you want."

"Fuck yeah," Katsuki moans, groaning when Izuku's thrusts start to slow. "You better fucking Claim me when you knot me, shitnerd."

"Of course, Kacchan," Izuku murmurs, leaning down so he can bury his nose into Katsuki's scent gland. "Whatever my omega wants."

Katsuki hums in response, baring his throat so Izuku has easy access to it. Izuku's cock is swelling in earnest, the knot forming near the base as he pushes into Katsuki. He quickens his pace then, reaching underneath to stroke his omega's cock. Katsuki groans into the sheets, hands twisted into the material as he enjoys himself.

Izuku's rhythm falters when his knot catches on Katsuki's rim. He strokes Katsuki's cock as he curses, his orgasm taking over in the next moment as he spurts come over Izuku's knuckles. Izuku cants forward rapidly, feeling his own orgasm rising up until his knot catches again.

He buries himself in his omega, teeth clamping down on Katsuki's scent gland when he finally comes. Katsuki shivers underneath him, his entire body trembling as the Claiming Bite takes and Izuku pulls away, licking at the wound to close it.

He rolls them over gently so they are now spooning and nuzzles Katsuki's scent gland. The newly awakened alpha in him hums in content at the motion, crooning at the scent of happiness that rolls of Katsuki in waves. Izuku presses a kiss to his omega's scent gland, letting them bathe in the afterglow.

"My sheets are gonna be a fucking nightmare to wash on Sunday, you shitnerd," Katsuki grumbles just a few moments later.

"That's what you get for turning me into an alpha, Kacchan," Izuku laughs in response.

Katsuki huffs, pushing his ass back on Izuku's knot and making the alpha choke. "Shut the fuck up."

Izuku wisely listens to his mate, his inner alpha more than happy to bend to the wants and needs of his omega.

day one of @bnhaomegaverseweek​ (hoping my love will keep you up tonight) 

The scale in his hands is bright red and glimmers pleasantly in the firelight. Izuku almost doesn’t know what to do with it.

Almost.

He looks up from his hand to the blonde omega standing in front of him and smiles as gently as possible. “Thank you. Which species of dragon is this from?”

Bakugou grunts and Izuku gets a face full of his nervous scent. “The Crimson Crushers. One of the whelps shed it’s first scale yesterday. Thought you might find a use for it.”

Izuku’s smile grows. “Oh, thank you! I’ve been meaning to gather more data on the Crimsons.”

Bakugou frowns, his face twisting with dull distaste. Izuku tilts his head to the side and tries to rely on his alpha instincts to parse the situation.

“Did I say something bad?” Izuku asks when his instincts wield no results.

“Yes,” Bakugou answers tersely. “They're called the Crushers for short. No one refers to them as the Crimsons anymore.”

Izuku grimaces. “Ah, yes. I apologize. I’ve been buried in the old texts all day, I guess my brain-to-mouth filter just isn’t in tip-top shape at the moment.”

Bakugou mutters something that makes Izuku flush pink. He decides to act like he didn’t hear it though and tries his luck.

“Sorry, what was that?”

“Nothing,” Bakugou bites out. “Let’s go eat.”

Izuku brightens. “Okay! Just let me put a few things away. I’ll be right out.”

Bakugou huffs and storms out of the tent but Izuku knows he’ll be standing by the entrance with his arms crossed over his chest and a sour expression on his face. It’s tradition by this point that Bakugou will enter his tent, bearing a gift of some kind, then drag him out to eat somewhere.

When Izuku first arrived at the dragon enclosure, Bakugou glared at him like he meant to kill Izuku right there and then. Of course, he hadn’t but that did nothing to diminish Izuku’s need to be careful around the blonde man and his explosive personality. Izuku was only here to gather more research on dragon scales and their healing properties anyway, not to get murdered by a pretty blonde omega who couldn’t stand the sight of him.

Except, that isn’t quite true anymore.

Two weeks after Izuku had joined them, one of the Emerald Emerger whelps went on a rampage and stomped hard enough to make multiple holes and flatten tents into the dust in the enclosure. Izuku had watched it all unfold with a quiet sense of horror until the whelp came face-to-face with him and Izuku reached out to it without thinking.

Maybe it was because their eyes were the same shade of green or because even as an alpha, Izuku couldn’t for the life of him emit any kind of threatening vibes, but the result shook up most of the camp. The whelp allowed him to curve his hand across its face and settled down, huffing and puffing like this was the last thing on earth it wanted to do. It curled itself around Izuku and growled at anyone who came close before it eventually fell asleep and Izuku was able to step away as the handlers rushed forward.

Kirishima was the only handler to turn back to him and check that was he was unharmed, but Izuku could feel Bakugou’s eyes on him nonetheless.

The day after, Bakugou barged into his tent while Izuku was in the middle of healing the food poisoning Sero had fallen ill with. He waited until Izuku was done before he presented him with a scale and explained that it came from the whelp Izuku had helped calm down and then left.

He came back later with dinner and sat with Izuku at the back table, grunting and humming as Izuku buzzed with conversation.

Now a month later, it is pretty normal to find Bakugou in his tent whether he needs to be healed or not. Izuku doesn’t mind it, he likes having company as he reads over his research and conducts experiments. Plus, having a dragon tamer and pseudo-expert present means he can ask almost any kind of question that may come to mind and get an accurate answer in response. He cross-references Bakugou’s answer with texts and known dragon facts, but even if he didn’t it wouldn't be so bad since Bakugou is always right.

If he knew any better he would probably say that Bakugou likes him but really, he sees it more as the omega grudgingly accepting him into their midsts after he had proven himself worthy to be there. He doesn’t mind it though, he can only guess how hard it is for Bakugou to make any kind of acquaintances since people would easily be scared off by his grumpy demeanor. Not Izuku, he has dealt with worse people, so Bakugou’s prickly exterior only pales in comparison.

Izuku finishes tidying up his journals and makes sure his equipment has been put away in the correct places before he exits the tent. Bakugou is standing by the entrance exactly how Izuku predicted him to be. He smiles at the omega and blinks in confusion when Bakugou flushes light pink in response.

He pushes that image out of his head as he follows Bakugou through the camp. They leave the grounds through one of Bakugou’s many secret passageways and walk quietly side by side. Izuku almost startles when Bakugou’s fingers suddenly interlace with his own, but one look at his blushing face keeps him from asking any questions.

Instead, Izuku swings their hands between them and grins when Bakugou doesn’t comment on it like he usually would. 

They come upon the main path to the nearby village and Izuku hesitates, glancing over at Bakugou again to examine his reaction. The blonde omega is tense and stiff, but his grip does not loosen.

It loosens something in Izuku's chest though, wiping a certain thought he had been having earlier away with a sense of realization. Was he wrong before? Is he denser than he thought? That would be pretty pathetic if he is. However, the best way to figure anything out is to ask and see what response Bakugou gives him.

So with that, Izuku stops swinging their hands and steps to the side, pressing himself closer to Bakugou. “Hey, I’m curious about something.”

Bakugou glances down at him, a blank expression on his face. “What.”

Izuku bites his lip, tilting his head up to meet the red, fiery gaze. He has always known that the omega is pretty attractive with his broad shoulders, tiny waist, and muscled arms. Izuku would have to be blind to not know that honestly, but with their faces so close together, he realizes that Bakugou is ultimately a lot more attractive than he initially thought. Startingly attractive.

He pushes that away though, not wanting to be distracted and returns to his earlier train of thought.

“Have you been courting me?” Izuku asks, amping up the amusement in his grin when Bakugou raises a brow at him. “It seems like you have been, but I don’t know you well enough to guess if you have been or not. So, are you?”

A tense silence follows. Izuku half wonders if Bakugou has ever courted anyone before and is surprised when the alpha in him roars at the mere implication.

“Yes.”

Bakugou glances away after another moment, jaw tight and shoulders stiff. Izuku frowns and steps even further into Bakugou’s space, guaranteeing the omega’s attention on him again.

Izuku nods his head once Bakugou has met his gaze once more and continues to walk forward. “Good. Should I court you in return?”

Bakugou huffs, but there’s the barest hint of a smile on his lips too. “Fuck no.”

“Okay!” Izuku replies, smiling once more as he leans his head on Bakugou’s shoulder. “This okay?”

“Yeah,” Bakugou mutters. “S’fine.”

Izuku hums. “Good.”

They walk in silence the rest of the way, the sun shining above them and the roar of dragons fading away behind them.

word count: 2770 

summary: Izuku would like to make Katsuki his actual mate, more than anything in this world honestly. He has only been waiting for a sign, some kind of signal to make sure that Katsuki wants it too. 

day six of @bnhaomegaverseweek​ (hoping my love will keep you up tonight) 

Izuku steps through the door and immediately finds himself with an armful of fiery omega.

Katsuki rubs his face ferociously into Izuku's scent gland, growling at all the other scents he finds there as Izuku closes the front door before they get another notice from the landlord for public indecency. Izuku would have to admit that he doesn't care too much about being a voyeur when it comes to society's standards for appropriate times to scent your mate, but he likes their apartment.

It is soundproofed which is great for when Katsuki yells at him or when Izuku himself shrieks out Katsuki's name. They have a balcony that Katsuki frequently uses to blast off when on his way to work and back without the media or public catching a glimpse of him. There's also an open-concept kitchen with enough space for Katsuki to work his magic while Izuku drools in the background.

All in all, the apartment is a great find. Especially since they live in the city and Izuku knows that Katsuki honestly doesn't care if their apartment is high-end or not, but it's in between both of their agencies so that makes this place even better.

"Kacchan, what are you doing?" Izuku asks when his omega is still clinging to his shoulders, face thoroughly buried in his neck. "Kacchan, come on! I need to shower and get changed for our movie night."

Katsuki growls into his skin, the sound sending pleasant vibrations down Izuku's spine. "Shut the fuck up, Deku. I'm scenting you right now so all those bitches know you're mine."

Izuku chuckles to himself, running a hand through Katsuki's sweaty, blonde hair. "Let's get clean together. You need a shower as much as I do right now and then you can scent me all you like during our movie."

He doesn't give his omega the chance to reply as he sweeps him off his feet and carries him bridal style further into their apartment. Katsuki grumbles but doesn't push away and instead adjusts himself so his nose is still firmly pressed into Izuku's neck. Izuku feels himself smile as he walks down the hallway and opens the door to the bathroom with his hip. He sets Katsuki down smoothly and pushes the tiny button under an inconspicuous flap on the side of Katsuki's hero suit.

The material around Katsuki's torso loosens considerably and Izuku shakes his head at the sigh of relief his omega lets out. "Kacchan, you know better than to wear your binder for so long."

"Shut the fuck up," Katsuki replies, but there is no heat behind his words so Izuku only sighs and reaches for the buckles holding most of Katsuki's hero suit together.

Izuku strips his omega down until he is bare-chested before he begins taking off his own suit. Katsuki growls at being moved around by Izuku's movements but manages to peel his briefs off while Izuku kicks off the reinforced leg guards that keep the bottom half of his suit pressed closely to his skin.

Katsuki hums in appreciation when he realizes that Izuku decided to go commando underneath his hero suit before the sound morphs into a growl and Izuku has his hands full of a fiery, blonde omega once more.

"Who the fuck did you get all nasty for, huh?" Katsuki practically spits in his face, face turning a bright red as his anger begins to grow. "Why the fuck did you not wear underwear today?"

Izuku rolls his eyes. "You ripped my last clean pair last night when you said I was taking too long. I have to bump laundry day a couple of days earlier than usual now and go out and buy more underwear, Kacchan."

Katsuki only rolls his eyes, the anger abated for now. "That's what you get for taking so long. You said you wanted me to fuck you and then you weren't even ready for it! What the fuck kind of shit is that, Deku?"

"Kacchan," Izuku whines. "Stop being so territorial for two seconds. You're gonna give yourself an ulcer."

"It'd be all your stupid fucking fault, Deku! Running around in no fucking underwear while you beat the shit out of villains. Who the fuck do you think you are?" Katsuki growls, one finger pressed into the center of Izuku's broad chest.

Izuku frowns, placing his open palms on Katsuki's chest, right above the crescent moon scars that his omega still feels insecure about sometimes. In the privacy of their own home, of course, Izuku knows well enough that Katsuki would never allow himself to be as vulnerable out in the general public eye as he is here with Izuku.

"I think that I'm your boyfriend and if anything, it was meant as a treat for you. You're always going on about my ass in spandex when you think I can't hear you. I thought you might like the view," Izuku mutters, feeling himself blush at the admission.

Katsuki scowls at him before he pulls Izuku into his embrace roughly and unexpectedly. "Better have been for me, you fucking nerd. You're mine. My alpha, no one else's."

Izuku laughs, pressing a kiss to the crown of Katsuki's head. "All yours, omega. Always."

"Prove it."

Izuku doesn't still nor does his breath falter. They have been together for years, but Izuku has not put a permanent Claim Mark on Katsuki yet. He has been thinking about it lately a lot, especially with Katsuki's territorial and possessive tendencies growing in intensity recently. Izuku isn't averse to the idea. He loves Katsuki, has always loved the aggressive omega ever since they were toddlers.

He just wasn't sure Katsuki wanted it.

Katsuki has spent most of his life hating the fact that he is an omega. It dwarfed the brilliance of his quirk when it first developed and his treatment made him angry. He lashed out, started fights, and burned a lot of people before Izuku could intervene. Eventually, though, his temper died down once Auntie Mitsuki forced him to take Anger Management classes. He apologized to those bearing scars thanks to his quirk and let himself be shuffled into the background.

He was still angry and he still lost control sometimes, but he never burned anyone that didn't deserve it again.

When they were filling out applications for high school, Katsuki was rejected from most places simply because of his sub-gender. It incensed Izuku enough to fill out various Alpha Mate permission forms from the schools Katsuki was applying to and slip them to Auntie Mitsuki so she could add them to Katsuki's applications with him being none the wiser. He knew it was wrong, considering he wasn't actually Katsuki's mate, but it had worked and that was all that mattered.

Until they got accepted to UA and Katsuki burst into his room, frothing at the mouth with rage that same day.

Izuku was sure that he would meet an early death right then and there, but after stumbling through his explanations, apologizing, and then crying when he admitted that he couldn't bear seeing Katsuki's potential waste away simply because of what he is, Katsuki began to calm down. He had taken deep breaths as the red seeped away from his face and smoke stopped curling around his palms. Then he had looked into Izuku's eyes and thanked him.

A genuine thank you, not one of those awfully-phrased insults veiled as thanks that he usually shot Izuku's way.

Once school started though, Katsuki took those Alpha Mate permission forms to heart and acted like Izuku really was his mate.

Izuku didn't mind it. He went along with it and always made sure they were moving at a pace that Katsuki was comfortable with. He always made sure that the omega knew his intentions until Katsuki blindsided him one day.

Apparently, Izuku had smelled too much like Ururaka and Iida which meant that Katsuki absolutely had to rid Izuku of their scents or the world would end. Katsuki scented him for the first time as a man on a mission, growling and grumbling under his breath as he buried Izuku in his natural scent. Izuku had just about melted, shocking himself when he began to Croon.

Katsuki hadn't even smelled surprised about the sound ringing around them in Izuku's bedroom. Instead, his scent turned spicy with smugness and something softer that took Izuku a long time to pinpoint.

Adoration.

From there, they have made their way here. Fake mates to boyfriends to something more.

Izuku would like to make Katsuki his actual mate, more than anything in this world honestly. He has only been waiting for a sign, some kind of signal to make sure that Katsuki wants it too.

He vividly remembers all the times Katsuki had spat at the idea of mates when they were kids. He didn't want to be anyone's housewife. He wanted to be a hero and no mate was going to keep him from that. He could not care less about what was expected from omegas after they had been Claimed, he was going to be a hero and no one was going to get in his way.

In middle school, Katsuki could often be found sneering at alphas and betas that showed interest in him alike. At UA, Katsuki wrapped himself up in Izuku and never once turned his head to pay attention to someone else.

Sometimes, Izuku thought that Katsuki was just settling. His omega could have anyone he wanted, could have a plethora of potential mates if he so wished. Maybe Izuku had messed with a lot of things when he filled out those forms at the end of middle school, but as time had passed, he realized that he didn't care.

Katsuki is his. Katsuki has always been his.

And if Katsuki had wanted someone else, he would have gone after them. He would have left Izuku in the dust and he would have gotten who he really wanted.

In all their years together, Katsuki has never wavered from him, has never mentioned someone else in passing or even entertained the idea of a future without Izuku in it.

When they finally got their hero licenses after three years spent at UA, Katsuki had invited him to dinner that night to celebrate - just the two of them. As soon as their food had arrived, Katsuki immediately began to show Izuku the apartments he was looking at and telling him about all the things Izuku would like and the features Katsuki himself appreciated. Izuku had barely looked at the photos, finding himself immersed in the sureness of Katsuki's voice as he spoke about them living together in a place of their own. He couldn't stop himself from leaning over and cutting off Katsuki's uncharacteristic rambling by kissing him, but Katsuki didn't seem to mind.

Soon after they moved into their first apartment together, Katsuki grew awfully territorial of his belongings and that had extended to include Izuku. Plenty of people frown at Katsuki's possessiveness over Izuku whenever he displays it in public. It isn't "appropriate" for an omega to act like that about their partner, but Izuku loves it. He has never cared that Katsuki isn't a "traditional" kind of omega or that the media demonizes him constantly for not being meek like omegas "should" be. Izuku doesn't want a partner that bends over backward to his every whim and need.

He wants Katsuki and he will always want him.

It is why Katsuki's possessiveness pales in comparison to Izuku's own.

Izuku would honestly travel to the ends of the earth for Katsuki and has fought off potential suitors before. Katsuki had understandably been angry about it the first time it happened, but by the third fight, he was scoffing and encouraging Izuku to win with his own special brand of not caring but actually caring quite a lot.

 What kind of fucking alpha are you if you lose to this shitty extra? Is that the best you can do? I could punch him to fucking Pluto, Deku!  Kick her ass or I'm kicking yours, you fucking nerd!

 He has fought long and hard for his omega. He showed his heart on his sleeve a long time ago and has been waiting for Katsuki to do it back. To give Izuku his heart.

So as he drags himself back to the present, Izuku asks, "You want me to Claim you, Kacchan?"

Katsuki rolls his shoulders as he glares at Izuku. He presents his neck where his unmarked scent gland can be in perfect view but he says nothing. Izuku watches him, brows furrowing together when he realizes he is going to have to prod at Katsuki for a clear and concise answer.

"Kacchan, I'm not gonna claim you until you tell me that you want it. I don't want you to be chained to me against your will," Izuku murmurs, unsure of the expression on his face but hoping with all his might that it is the right one.

"Shut the fuck up, Deku! You always act like it would be a fucking nightmare to be your mate, but I've been waiting for fucking years and you still haven't taken the hint, idiot!" Katsuki spits, angry once again.

Izuku blinks at him in astonishment. "Years? Why didn't you just say so!"

Katsuki's glare darkens. "I have!"

"No, you haven't! If you had, I would have done it in a heartbeat, Kacchan! Of course, I want us to be mates, but I'm not going to Claim you just because you dropped hints and never said it explicitly," Izuku jabs back, hands fluttering about in nervousness. "Kacchan, I need explicit consent from you to Claim you."

"Well, you fucking have it! Claim me already, you stupid fucking alpha!" Katsuki yells, hands clenched at his sides in fists.

Izuku steps forward and grabs Katsuki's hands, pulling his omega in close. "Kacchan, you know a Claim Mark won't change anything, right? You've always been mine - always will be mine. All mine, Kacchan."

The beginning of a Croon is building up in his heart, already beginning to move towards his lungs where it will make its way up to his throat and past his lips. Katsuki's eyes are somber, for once not full of anger or bottomless rage about something or other. Izuku struggles to hold the Croon down as he waits, not breaking eye contact with his omega.

"Of course, I fucking know that, dumbass! I just want this shit to be official already. I want everyone to know that you're mine. You have always been mine, right? Otherwise, you would have fucked off when we were kids. I'm not fucking stupid, shitnerd. You always had these stupid ass hearts in your eyes whenever you looked at me and I knew that you were the best when we left middle school. I deserve only the best and you're fucking it," Katsuki growls, pulling himself closer until their chests are bumping against one another. "Now fucking Claim me already. You know I can't stand all this emotional bullshit."

Izuku feels his lips split into a bright, large smile. "Okay, Kacchan. Whatever my omega wants."

"Finally!" Katsuki scoffs, presenting his neck once again. "Now get on with it, fucking nerd."

His nose makes contact with Katsuki's scent gland first and he hums as Katsuki shivers. Izuku breathes over his neck and collarbone before his tongue swipes across the surface. Katsuki outright moans, shameless and turned on, but Izuku ignores that and licks his scent gland again.

He almost can't believe that he finally gets to have this. He gets to keep his omega all to himself for the rest of their lives. He gets to Claim Katsuki as he always wished to when he was a kid and while growing up. Izuku would have been okay with the quiet pining he endured all throughout primary and middle school, but then he had to go and fill out those forms and change everything.

At least it was a change for the better.

Izuku feels his canines sharpen as he opens his mouth wide and sinks his teeth into Katsuki's scent gland. Katsuki immediately goes limp in his embrace, moaning Izuku's name like some kind of prayer. The Croon that Izuku was fighting back erupts from within him and echoes around them in their plush bathroom, cocooning them in the sound of Izuku's love for his beloved Kacchan.

He thanks his lucky stars for the sound-proofed walls of their apartment once again as Katsuki melts into him and attempts a Croon in return.

chapter six of when i fill them, they’ll shine forever 

"If you're here to give me some sympathetic speech or some shit, I will kill you, Pinkie," Katsuki spits over his shoulder.

"Eh?" Pinkie startles, scrambling to compose herself as Katsuki turns to look at her. "I have no idea what you mean."

Katsuki narrows his eyes at the way she nervously scratches the back of her head, her smile much too wide to be genuine. Pinkie scuffs the toe of her shoe against the floor, her arms dropping to her sides so she can play with the ends of her school jacket. Her scent is as sweet as any other omega’s but there is a sour aftertaste to it that makes Katsuki wrinkle his nose in distaste.

"What the fuck do you want? I have places to be," Katsuki says as he crosses his arms over his chest.

He doesn’t know anything past a few of his classmates’ quirks, much too busy with bettering himself and challenging his mates to give a shit about anyone else. Shitty Hair and Pikachu are showing some potential since they have enough of a backbone to socialize normally with him instead of fearfully or putting him on a pedestal. Most of the others will be unimportant to his story in the long run and Katsuki isn’t usually the type to write people off so soon, but Pinkie herself hasn’t impressed him in the least. 

“I just um-” Pinkie flushes, fingers twining together nervously. “All the girls wanted to thank you.”

Katsuki frowns, suddenly confused. As far as he knows, none of the girls want to be within two feet of him. He has no idea why they would want to thank him for something.

The only thing he can think of that would be spoken about is the Perverted Grape incident that happened earlier that day. Katsuki is waiting for Deku to finish talking to Glasses, Todoroki already having left a few minutes before. He wants to go to Deku’s and gorge himself on Auntie Inko’s cooking while he avoids going home where his mom will scream for blood and his dad will flutter nervously around him for the rest of the weekend. He already had Glasses, Hundred Arms, and Shitty Hair try to comfort him in their own shitty ways about Perverted Grape, he doesn’t need any more of this crap today.

“What the fuck is this about?” Katsuki asks, glaring down at Pinkie. “You have five seconds to speak or I’m walking away. One.”

“Thankyouforgettingridofmineta!” Pinkie shouts, bowing at the waist once before she runs away.

Katsuki scoffs as he watches her leave. “As if I did it for any of you.”

“Did what, Kacchan?” Deku’s voice pipes up behind him.

“Nothing, you shit nerd. Let’s go already,” Katsuki grumbles, barely even reacting to Deku’s sudden appearance.

His alpha’s scent is more familiar to him than his own so if Deku really wants to startle him, he is going to have to work harder than that.

Katsuki takes Deku’s hand and leads the way towards the train station, already imagining all the dishes his Auntie Inko will prepare. Deku follows behind him quietly, not having to say a word for Katsuki to understand his alpha will always support him.

The sports festival is turning out to be fucking boring.

Katsuki delivered his "speech" before the first challenge began, which was really just him pointing out a fact by stating that he and his mates were going to mop the floor with all of them. No need for everyone to get their fucking panties in a twist at the truth.

They had taken one look at the mouth of the tunnel before both his mates grabbed hold of Katsuki’s arms and held on tight as he shot them over the other students piling up beneath them. Many yells and shouts had followed them but Deku only whooped as they came out of the other side and got their first glimpse of the obstacle course prepared for them. 

The zero pointers from the entrance exam rose up to greet them but Todoroki froze one and Katsuki blew up the one beside it at Deku’s request. Deku had grabbed a stray piece of the now broken robot as they flew over it while Todoroki directed ice back at the other students to cut their competition in half. At the pit, Todoroki made more ice to make them a path straight across and Katsuki used more of his blasts to ski them over the pit in no time at all. 

By that point Katsuki and Todoroki had practically ruined the obstacle course as they held Deku between them, all three of them keeping first place easily. Then Deku had pulled himself away from them at the third obstacle, dropping onto his knees to dig at the edges of the landmine before Katsuki got the memo. Together, they dug up the explosives and put them in a pile together.

Todoroki had just enough time to grab Deku's shirt and Katsuki climbed onto his alpha's back as Deku held up the piece of the robot that he had nabbed earlier. His alpha then slammed it into the explosives and all three of them were thrown into the air, sliding past the finish line easily and more importantly, together.

The second challenge hasn't been that big of a challenge either actually. Katsuki grudgingly allows Round Face to join their team after Deku brings up his plan and when the countdown begins, Todoroki makes ice appear in a circle around them while Round Face slaps her hands on the backs of Katsuki’s mates before pressing her fingertips together with a determined look in her eyes. Katsuki settles Deku on his shoulders and waits until Todoroki and Uraraka have grabbed hold of his alpha’s arms to shoot them up in the sky. More yells and shouting follows them but Katsuki ignores it. He knows they are not breaking the rules through anything but a technicality and while last year, he would be enraged about using such a cheap tactic to win, now he only cares to shield his mates from any harm that may befall them. 

Despite the lack of a real fight, their team is doing exceptionally well by staying out of other students’ grasps. The only time anyone gets near enough to almost ripping the headband worth a million points off Deku's head, Todoroki's left side erupts with the barest lick of flames before his ice overcomes some random girl’s vines. Katsuki felt the almost unbearable heat of Todoroki’s fire tease the back of his hand as he prepared himself to power off an explosion and can't help the sharp intake of breath that he takes through his teeth at that moment.

Which is why he is only slightly surprised when Todoroki asks him and Deku for a word in private during the lunch break. Once the break is over, all the stupid extras will then ready themselves for the games UA's staff has prepared for the losers who didn't make it to the final round so technically, they have a longer break than most. Katsuki exchanges a not-so-subtle glance with his alpha before he nods and allows Todoroki to lead the way.

As soon as they are alone, Todoroki tells them his life story. 

All of it. 

The quirk marriage. The forced mate bond. The breeding. The training he began at age four. His mother losing her grip on sanity. The isolation from his siblings and peers alike. The abuse he has withstood ever since then. The resentment and anger Todoroki has carried for countless years. The determination to never use the quirk he inherited from his father.

Every single, excruciating detail has Katsuki's blood boiling and his hackles rising. His body calls for blood, the need to defend and fight and tear limbs apart almost overcomes him.

He doesn’t understand how a parent can look at the life they helped bring into this world and not want to protect them with all their power. Deku has an idea if his claim of not being All Might’s secret love child can be believed, but Katsuki has never faced that misfortune. Not even his coming out impacted the relationship he had with his parents much - not in the way that most would expect anyway. Katsuki does not understand and he never will but he does understand that what both his mates’ fathers have done and are doing now is wrong.

Wrong and awful and horrible. Downright evil in Todoroki’s case. That is more than enough to warrant Katsuki’s bloodlust. He’s sure his parents would understand why he murdered the Number Two Hero anyway. Auntie Inko most definitely would. Hell, probably Yagi-san too, especially considering the way he dotes on Deku. 

Regardless, Katsuki has already made up his mind.

"I am going to fucking kill him," Katsuki spits out between clenched teeth, his hands smoking and curled into tight fists at his sides. "No, no. I am going to destroy him! I'm gonna rip off his balls and feed them to him! I'm gonna hold my hands over his skin and see how well he likes getting burned!"

Katsuki continues, his methods of torture growing more grotesque and painful as he does, all while ignoring the surprised and somewhat wary look on Todoroki's face. Deku is silent beside him, but his scent tells Katsuki enough.

Their alpha is angry. 

Deku is trembling, his eyes flashing gold and hands curled into fists as well. The air around them reeks of ozone and Katsuki feels the ridiculous urge to sneeze. Todoroki’s gaze keeps flickering between the two of them, unsure of who needs his attention more: his alpha who is rapidly losing his grip on his control or his omega who is ranting about every which way he will harm his father.

"Aren't you going to tell me that killing is bad and I don't know what other fucking nonsense you preach and shit?" Katsuki asks when Deku's scent sours enough to bother him. "I'm gonna murder the Number Two Hero, you fucking nerd. Shouldn't you stop me?"

Say something, Katsuki doesn’t plead aloud. Say you agree. Say you’re with us, no matter what.

Deku tenses all at once then sighs, his body going lax as he closes his eyes and leans his head back on the wall behind him. "If it was anybody else, literally anybody else, I would say yes."

Katsuki smirks, the edges of it sharp enough to cut. "But?"

"Not in this case," Deku finally says, his scent still angry and now frustrated.

"I am fully capable of killing that bastard, you know," Katsuki continues, eyes flickering between both of his mates. "I could go and murder him right now and I would be glad to be thrown into jail for it. My parents would probably throw a fucking party."

Todoroki looks at him like he's insane, but Katsuki ignores him. He focuses on Deku instead, watching the corners of his mouth twitch with a smile, the sour anger in his scent slowly starting to bleed away.

"I know, Kacchan," Deku agrees, opening his eyes which have now returned to their normal color and leaving Katsuki horrified as they start to water.

Katsuki bites his lip, looking back at Todoroki again who is staring open-mouthed at Deku in shock. "Do you want me to?"

He means it as a question for them both but it is Deku who answers. "Yes, but you shouldn't. People would paint you as a villain and that's not who you are, Kacchan.”

“Shut the fuck up, Deku,” Katsuki bites back but there is a smile on his face and no heat in his words.

“Okay,” Deku replies with a tired smile.

Katsuki pivots to stare at Todoroki, pinning his beta with his gaze alone. “And you, you bastard, come here!”

“Are you going to kill me?” Todoroki asks as he stands up straight, his spine probably in pain due to how quickly he came to attention.

Katsuki's grin turns sharp once more. “If you Order me again, then yes, but just get your ass over here already! ”

“Wait, you Ordered Kacchan?” Deku asks, head swiveling between them both in confusion.

"Twice, the fucking shithead!” Katsuki admits.

Deku's eyes turn flinty before they soften once more. "You must have a death wish, Todoroki-kun. Please, don't ever do that again."

Katsuki huffs, crossing his arms over his chest as he glares at his alpha. "I don't need you to defend me, fucking Deku!"

"I know," Deku murmurs, "but sometimes, you want me to and I don't really appreciate the fact that someone would Order you, even if he's our mate, Kacchan. Todoroki-kun, seriously, don't do that again."

"Shut up, Deku," Katsuki spits out at the same time that Todoroki says, "I won't Order you again, Bakugou-kun."

"Good," Deku huffs as Katsuki moves closer until he can sling an arm over his alpha and tuck him into his side. "Now get over here. We're going to scent you so your father knows he'll have plenty of things to explain the next time I smell him on you."

Katsuki nods sagely. "Deku will destroy him."

"Why would he do that?" Todoroki looks at Deku like he can't imagine the alpha going toe-to-toe with his dipshit of a dad, but Katsuki knows better. And Todoroki should know better too after what happened the week before in the locker room's bathroom.

"Because you're our mate, you fucking bastard," Katsuki growls, reaching out and grabbing hold of Todoroki's arm before he drags him closer. "We'll end anyone who fucking hurts you. You're mine now and I don't like it when people touch my things. I beat the shit out of anybody who dared to lay a hand on my alpha and I'll beat the shit out of anyone who hurts my beta too."

Deku smiles at Todoroki from underneath his arm, his scent calmer and steady like before. "Don't worry about it, Todoroki-kun. Kacchan is just really overprotective. You'll grow used to it."

Todoroki is stiff underneath Katsuki's hand, but, slowly, he starts to relax as well. He leans into Katsuki's side and lays his two-toned head against Katsuki's shoulder. On his other side, Deku does the same, mirroring their mate. They stand there for a moment, huddled up in each other's warmth as they allow their scents to slide across one another, mingling and intermixing. Katsuki is certain that no one is going to speak for some time yet, so he's slightly surprised when Deku does.

“Your quirk is your own, Todoroki-kun.”

“Hm?” Todoroki hums in response, his head shifting against Katsuki’s shoulder.

Deku leans forward until even Katsuki is having difficulties keeping his eyes on them. “Your fire is your own. Everyone else here is using a hundred percent of what they’ve got to make it. It would be wrong of you to do this with only half.”

Todoroki stills in Katsuki’s embrace, expression shifting until his face is blank once more. Katsuki can physically see all the walls Todoroki is putting up again and he cannot have that.

“We can talk about that later, you little shits,” Katsuki cuts in. “Deku, seriously not the fucking time.”

His beta’s scent pulses for one short breath before it calms, Deku oblivious to it all as he starts to say, “Todoroki-kun should work with a hundred percent of what he has too, Kacchan! Otherwise-”

"Shouto."

"Huh?" Deku asks, like a fucking idiot as if Todoroki's intentions aren't clear enough.

Todoroki only blinks at him though, his scent still remaining calm and focused. "You can both call me Shouto."

Deku brightens considerably, his smile like the sun breaking through a heavy layer of overcast while he pushes the quirk issue off to the side for now. "Ah, well you can call me Izuku and Kacchan Katsuki!"

"No, he can't," Katsuki scowls.

"Yes, he can," Deku replies instantly, his smile never faltering. "Go sulk another time, this is loving and supporting our mate hours right now!"

Katsuki can't help the startled laughter that escapes him, but he lets it run its course when Deku only brightens even further at the sound and Todoroki relaxes against him again. "Shut the fuck up, Deku. That meme is as old as balls."

Deku's grin only grows bigger, the edges curving dangerously but he says nothing and wraps his arms around Katsuki's waist. Todoroki too settles further into their warmth, his scent now laced with a dash of content.

From the corner of his eye, Katsuki can see the hint of a smile on his beta's face. The sight alone does weird things to his heart that he promptly ignores in favor of enjoying the company of his mates.

Deku and he run into Endeavor before starting their second fight in the third challenge and Katsuki wonders how the Flaming Piece of Shit got out of there alive.

Considering that All Might was also present, Katsuki is doubly confused about how Endeavor is still breathing.

“Come on,” Katsuki spits as he drags Deku out the door. “Fuck everything else and focus on this stupid match. If you let your quirk break you again, dipshit, I’m taking our beta in the divorce.”

Katsuki isn’t happy at all about the team matches but considering that there are many mated students in the sixteen contestants left for the third challenge, he supposed that it made some lick of sense. Not that he’s going to admit that out loud anyway.

Deku laughs, following behind Katsuki willingly, but his smile dies as they round the corner and run into the last person either of them wanted to see.

They have seen the Number Two Hero plenty of times on television and social media. Katsuki thought he was pretty average looking when he was younger but at that moment he is ugly beyond belief. His facial hair is made up completely of fire and spare bits of it run through his hair. He is tall and in his hero suit but there is nothing about him that shows he is a hero in Katsuki’s eyes.

Instead of the mild admiration Katsuki used to feel for this man, all he can focus on is the hate and rage that’s building up quickly within him.

“So you’re the alpha who’s staked a claim on my son,” Endeavor says like he never expected anybody to try and interfere with the plans he had forced upon his child’s shoulders.

Katsuki bares his teeth at him, forcing himself to stay silent. Endeavor’s eyes linger on Deku’s arm where he is grabbing hold of his alpha. His gaze flickers to Katsuki briefly, looking him up and down as if he is a piece of meat being put on display at the market before he focuses back on Deku. Katsuki can’t help the cold disgust that rolls down his spine when the Flaming Piece of Shit’s eyes are no longer on him. Deku shifts beside him in response, subtly putting himself in front of Katsuki to shield him from view.

“And you’re Shouto’s father,” Deku points out, the anger in his voice plain for anyone to hear.

Endeavor’s brows raise up for a moment before his face settles back into its usual scowl. “Your omega. She’ll do fine but if you don’t prove you are the best alpha around, neither of you get to have him.”

Deku growls and the overbearing scent of ozone fills up the hallway. Katsuki holds onto his alpha tighter while allowing his lips to curl back and make his snarl look more aggressive.

“You don’t decide that for him,” Deku snaps. “And don’t refer to Kacchan as a girl. He will rip out your tongue for such disrespect.”

Endeavor’s gaze flicks back towards Katsuki at this and Katsuki snaps his teeth at him, wanting nothing more than to do just that.

Shouto had told them about all the awful crap his father had done but this - what he just said - takes the fucking cake. Katsuki wants to let go of his alpha and watch him tear into this arrogant beta until there is nothing recognizable left. He doesn’t though because he isn’t stupid and the only person allowed to go to jail is him, but the idea itself is still very tempting.

Fortunately, Yagi-san’s smell rises up behind them announcing his presence. Katsuki doesn’t look back to see his arrival, not trusting Endeavor enough to take his eyes off him but he does smell it when Yagi-san realizes what is going on. It would have been difficult not to, considering Deku is sending out angry and agitated alpha pheromones for everyone in the entire building to smell. Even the lowliest beta with the worst sense of smell would be able to tell that Katsuki’s alpha is in distress.

Within two seconds, Katsuki is facing the broad back of the Number One Hero. All Might is in the shifted form he uses for public appearances and has his arms extended by his sides in a way that appears natural but effectively blocks them both. The fact he did this in a way that did not draw any attention to them at all is only another reason why Katsuki immediately begins to calm down when All Might appeared.

“Endeavor, what are you doing to my students?” All Might rumbles, acting as if he had not stumbled over the end of his question.

Katsuki can no longer see the expression on Endeavor’s face but he can hazard a guess about it well enough. “Wishing them luck.”

All Might’s stance doesn’t relax in the least. “Then you may go now. These two are due for their match soon.”

Endeavor merely huffs and walks away then. All Might doesn’t move from his stance until the other man is no longer nearby. He turns and smiles at them, dropping a hand on both their shoulders when the coast is clear. Katsuki allows it, his anger still pulsing dangerously within him even if he knew they are safe with All Might now present but it is dying down nevertheless.

“What happened?” All Might asks, his blue eyes glinting dangerously under the hallway halogens.

Katsuki tells him. He keeps quiet about what their mate had told them earlier that day because it isn’t any of his business to share until his beta is ready to get help, but he holds nothing back about the conversation they just had with the Flaming Piece of Shit. All Might’s eyes turn almost black with the force of his anger, more ozone joining the air around them.

(And Deku had seriously thought Katsuki wasn’t going to assume that Yagi-san was his dad?)

“He won’t bother you again. You have my word,” All Might vows. “Now run along. Your match is starting within the next three minutes.”

They both nod and are rewarded with pats to their heads. Yagi-san then steps to the side so he is no longer blocking the path and Katsuki drags his alpha away before Deku can add more fire to the fuel.

Katsuki and Shouto share first place, Deku taking second and Emo Birdbrain taking third.

He would consider it a loss any other time, but considering all the crap Shouto has been put through and shared with them today, Katsuki just rolls with it.

(And no, he does not miss the fact that All Might hugs his alpha just a little too long to be normal after he drapes their medals over their heads during the awards ceremony. Going by Shouto’s thoughtful hum beside him, their beta doesn’t miss it either. That conversation should be fun.)

Later, he still takes pleasure in burning and blowing up all of his and Deku's Endeavor merchandise.

He takes greater pleasure in watching Shouto try and keep a straight face as Katsuki blatantly flirts with him when they get ice cream the next day. Deku's flirting is a lot more subtle but they both relish at the sight of Shouto's flushing, blank face over a banana split.

Of course, not all good things last. Katsuki had learned this fact early on in life.

He knows it isn't true when people say that the only way is up. Life isn't that easy and it has never been especially kind to Katsuki of all people. He doesn't mind that fact. He understands that is just how things work and that it is the way of life no matter how much he may wish it not to be. It's just how things are and he gets that.

He just didn't expect the rug to be pulled out from under his feet so soon is all.

day three of @bnhaomegaverseweek (hoping my love will keep you up tonight) 

When the whistle blows, Katsuki is already taking leaps and bounds deep into the forest.

He knows exactly who he wants and he’s going to get them. He deserves only the best and Deku has proved over and over again that he is the best omega Katsuki could ever even think to ask for.

Plus, he cannot deny that it wouldn’t give him an ego boost having the Number One Hero all to himself. Or well, at his mercy anyway. Katsuki can’t really claim that Deku will be his alone because he isn’t the only one Katsuki has his sights set on.

For now, he focuses on finding Deku’s scent of pine and cedar, the constant underlying bitterness of ozone shaping the omega’s scent exactly to Katsuki’s wants. He knows how fast and agile his intended is and while there is someone else, Katsuki needs to focus on the more difficult prize first.

So he laser focuses onto the scent and bites his teeth into it, refusing to let go or lose it. The scent infiltrates his nostrils, keeping his attention and forcing him to run deeper and deeper into the forest they chose to hold the mating run in. Katsuki passes by Ururaka at one point but ignores the warning growl and the startled look on her face as he continues to run past. 

The trees are mostly a blur to him when he decides to take to the skies with the use of his quirk, closing in on the flash of green he catches out of the corner of his eye jumping from tree to tree. He angles himself in that direction and drops back to the ground as carefully as he can, patting his pants harshly until the smell of smoke can no longer mask Deku’s scent and runs faster than before once his feet touch down. He crosses four streams as he moves and Katsuki chides Deku in his head, thinking of the possible illnesses the omega might fall to thanks to this run and his determination to make it a challenge for Katsuki.

Katsuki is going to give that idiot the sternest talking to once he finds him.

Eventually, he starts to see flickers of green electricity flash in front of him through the trees. He has already run past some more of his old omega classmates but ignored them all the same way he ignored Ururaka for this.

For the emerald-eyed omega with wild, dark hair who used to sleep in Katsuki’s crib with him when they were still pups. For the boy who dragged him away from a confrontation when it seemed like Katsuki would lose control and burn someone. For the boy who threw himself at a sludge villain in some vain attempt to save Katsuki when he was still quirkless. For the boy who refused to stop being Katsuki’s friend even when Katsuki himself did not want to cause any more harm to him and pulled away before running right back. Katsuki knew that Deku was his the moment he could think of and remember any cohesive thoughts. Deku has always been in his life and has always been his.

Was he angry when his mate turned out to be quirkless? No, he was only irritated and annoyed that Deku was crying over it like it meant the end of the world for him. Katsuki wasn't going to hold his best friend back from his dream and he tore into anybody who thought they possibly could, peers and teachers alike. No one told his mate what to do except for him and Auntie Inko.

Was Katsuki angry when Deku ended up having a quirk after all? A bit, seeing as All Might had given it to him so Deku had never actually lied about being quirkless in the first place, but did lie about how he got it. And to Katsuki’s face of all things. As if Katsuki can't see through his bullshit and lies, the fool.

But then Deku had presented as an omega and Katsuki couldn't do anything but rage about in his room while his mate went through his first heat alone. Deku got suppressants soon after and hasn't endured any of his heats since. It almost made Katsuki angry until he viscerally reminded himself that he had no right to demand something from Deku that he didn't want to give. No right at all. No matter if Deku was his or not, Katsuki could never force him into that.

Deku became friends with that Half-and-Half bastard soon after presenting and Katsuki growled at him in warning each time he neared. He only stopped when he realized that Todoroki would grow paralyzed with fear each and every time an alpha acted aggressively towards him.

Katsuki took to growling at anyone who got too close to Todoroki soon after that. Then he spat in Endeavor’s face and had to be held back by All Might, Aizawa-sensei, and Deku alike before he really tore into the number two hero like he wanted to.

Last week, the plans for the mating run had been finalized. Katsuki immediately dragged both the omega and beta to his apartment for a long and overdue talk. He laid his cards out on the table and was grateful when they did the same in return. Deku had even admitted to getting off his suppressants so that he could fall into heat by next week when the mating run was in full swing. Todoroki had admitted that he wouldn’t actively hunt after Deku but would keep close so that Katsuki wouldn’t have to waste too much time trying to catch him before Deku’s heat overcame them.

Now Katsuki has a plan and it all starts with catching Deku. Deku who he can clearly see muttering up ahead, trying to decide which direction to take.

Katsuki moves silently forward and jumps onto the omega’s back once he is close enough. “Gotcha, fucking nerd. Your stupid, big brain was always gonna be your downfall.”

Deku laughs, still in his hold as he presents his neck. “I got carried away with strategy and forgot to enact it. Next time, I’ll make it worth your while, alpha.”

“See that you do,” Katsuki murmurs against his ear before he leans down and bites down on Deku’s scent gland.

His omega goes limp in his hold, whining such a pretty noise for anyone close by to hear that Katsuki can’t stop himself from crooning. Deku seems to come back to his senses as Katsuki’s croon echoes around them, but he doesn't comment on it, only turns around and kisses him once before tugging the collar of his shirt away before he bites down on Katsuki’s scent gland in return. Katsuki’s croon grows louder as he starts to feel Deku in the back of his head, his alpha’s muttered thoughts and feelings developing slowly. Deku licks the wound and pulls them back the way they came.

“Shouto’s over here. He stayed mostly behind you the entire time,” Deku says with a bright smile.

Katsuki grins back, one of his more genuine ones. “Lead the way, omega.”

Deku keeps a tight grip on Katsuki’s hand as they run. He can already smell the pre-heat on his omega, how his scent develops a spicy curl to it that Katsuki has to resist.

He catches Todoroki’s scent soon enough, the smoky, soapy scent of his soon-to-be beta pulling him forward. Deku lets him lead, never letting go of his hands as they flash through the trees.

In a clearing up ahead, they can see Todoroki’s distinct head of two-toned hair laid back against a tree trunk. He is sitting on the ground, legs folded one over the other as he waits. Katsuki can see a few alphas lurking in the dense shrubbery, but one growl from him is all it takes to scatter them and get Todoroki’s head to snap in their direction.

“Found you,” Katsuki taunts as he rushes forward, letting go of Deku’s hand to grab Todoroki instead and hold him steady. “You’re mine now.”

Deku whines behind him. “He’s ours, Kacchan. You can’t be so selfish.”

Todoroki laughs, tilting his throat towards Katsuki. “I’m only yours if you’re mine back.”

Katsuki snorts inelegantly. “Obviously, fucking Half-and-Half.”

With his throat now completely barred and offered up to the alpha, Katsuki buries his nose into the beta’s scent gland before he pulls back. Deku is on his other side now, crouched down and offering his throat for Todoroki as he closes in. Katsuki spares them another glance before he darts forward and bites down hard.

Todoroki cries out quietly then goes limp in Katsuki’s hold the same way that Deku did earlier. Katsuki keeps his teeth in firmly the beta’s skin for another moment before he pulls back and licks the bite, moving to the side so Deku can come forward. Deku angles his mouth until his claiming mark lies crisscrossed over Katsuki’s on Todoroki’s scent gland, eyes closing in bliss once he has bit down.

Their beta is practically boneless as he lies back against the tree, but he opens his own mouth and smiles gratefully at Deku when the omega comes close enough for his throat to be within easy reach. Katsuki watches as Todoroki bites down on Deku’s scent gland, both his omega and beta falling all over themselves once Todoroki has pulled away. Deku’s heat is growing, the smell of it becoming stronger with each passing moment. Katsuki wanted more time for this part but they’ll have to settle for a quick Claiming lest Deku falls into heat and they don’t get to finish properly before then.

Katsuki comes forward again and leans over Deku’s limp form in Todoroki’s lap as he offers up his own throat. Todoroki sniffs at his scent gland before he leans forward and bites down hard enough to puncture through Katsuki’s tough, alpha skin. Katsuki croons again, louder and without shame this time. Deku’s spicy scent rises to greet the sound and Katsuki groans into Todoroki’s ear when he catches a whiff of Deku’s slick.

Todoroki smiles as Katsuki stands and pulls them both over his shoulders like some kind of barbarian carrying his woman away to have his way with her. In a sense, the image isn’t wrong per se, but Katsuki knows better than to believe his omega and beta won’t make him work for it. He would expect nothing less from either of them anyway.

He needs to get them to that cave he scouted out two days before and made his temporary den, preparing it for this moment. It’s stocked up with water and food, candles and lanterns stuck wherever he could make them fit. He made multiple trips grabbing everything he could think of, including extra sets of clothes for when they were finally done, that stupid plush bunny Deku has had since they were kids, and a heated blanket Todoroki claimed he might need if he uses his ice quirk too much while helping Deku through his heat.

Deku slaps his ass as Katsuki begins to run, giggling and leaking even more slick when Todoroki laughs with him. Katsuki growls at them both to shut them up, dismayed when that only makes them laugh harder. The alpha’s cave is not far from here though and he arrives within three minutes, laying his mates down on the furs and soft blankets he brought with him. Immediately, they curl into one another, already kissing each other as they paw and remove their clothes while Katsuki closes up the entrance to the cave until all he can smell is the mingling scents of his mates and candles burning bright.

He turns back to find them glowing in the candlelight and Katsuki dives between them, kissing them with abandon. A happy, soft feeling bubbles in his chest before it travels up to his throat and escapes past his lips in the form of a loud and proper Croon. His mates whine at the sound, throwing themselves on top of him in an uncoordinated rush until Katsuki buries his hands into their hair and pulls them up for a messy, three-way kiss between them.

Never let it be said that Katsuki doesn’t get what he wants.

chapter three of when i fill them, they’ll shine forever 

Katsuki stays in his room until dinnertime when his grumbling stomach and the angry shouts from his mom forces him to come out of hiding.

His dad is home now and heard all about the dumbass sludge villain on his commute here from the studio. Katsuki endures the mother henning, assuring his dad multiple times that he took off his binder as soon as he got back and no, he is not even wearing a sports bra either. His dad doesn’t look assured in the least, but then his mom butts in and asks if it really was Izuku who rushed in before All Might showed up.

Katsuki fights back a growl, but his mom sees right through his bullshit. She's always been able to do that.

“You sent Izuku packing, didn’t you?” she asks.

“Shut up, old hag,” Katsuki deflects.

His mom sighs, rolling her eyes heavenwards in exaggeration. “You’re being stupid, ungrateful brat.”

“Love, this really-” his dad tries to cut in.

“No, he needs to hear it,” his mom interrupts before looking back at Katsuki and frowning like he's the one who did something wrong. “You’re being stupid. Izuku is your alpha. Of course, he’s gonna risk his life for yours, it’s built into him. You would do the same stupid stunt too, that’s why you’re mates. Because you love each other so much that you would do anything for your mate no matter the cost. Don’t make that face at me, you brat! You know that I’m right.”

Katsuki sulks, chopsticks picking at the food that was set in front of him during his dad’s mother henning earlier. He doesn’t feel all that hungry anymore, but he knows that he needs to eat. If he doesn’t, his dad will go into a flurry and his mom will ultimately force him to finish what’s on his plate anyway.

“I never asked him to,” he finally says, chancing a glance up at his mom.

She stares back, giving nothing. “And he would never want you to! The least you could have said is thank you before you ripped him a new one. I’m sure those useless heroes at the scene did enough of that crap since they couldn’t do anything better.”

“I can’t even fucking look at him right now.”

“Why?”

Katsuki growls, hands pulling at his hair in frustration as he feels the burn of tears in his eyes again. “Because I was weak! I was just a shitty, useless omega who had their alpha save them and now that’s all anyone is going to remember from that shitshow! My alpha was in danger because of me and I promised to protect him, but I couldn’t even fucking do that!”

His mom’s voice raises in tandem with his own. “You really are fucking stupid if you think-!”

“Let me handle this dear,” Katsuki’s dad cuts in, one hand on his beta’s shoulder.

With a deep exhale, Katsuki watches his mom calm down underneath his dad’s hold. He sets his chopsticks down and waits, hands folded together in his own lap as his father’s gaze swings from his mom to him instead. He knows that his dad is about to give him a lecture the equivalent to the smackdown of the century and he should probably save himself and just run, but Katsuki is no coward.

“Katsuki,” his dad begins with, “you are not weak and I would pity the fool who would ever believe that of you.”

Indignation rises up in him causing Katsuki to sit up straight in his seat, the beginning of a protest on the tip of his tongue before it dies as his dad shoots him an uncharacteristic glare and continues.

“You and I both know that Izuku did not do what he did because he views you as weak. He risked his life for the chance of saving yours because you are his mate. You are his other half and if he stood by while your life was in danger, he would never be able to forgive himself. And you know what?” His father asks, tilting his head to the side to see if Katsuki will answer.

Satisfied with the silence, he plunders on. “I would never forgive him either if he only stood by and did nothing like those so-called heroes who were there at the scene. Not one of them was going to even try and save you in the end, Katsuki. They were going to let my little boy die without even doing anything to prevent it. Izuku is a true hero and you’re lucky to have him as a mate.”

Katsuki scoffs but doesn’t say anything. Instead, he waits and is rewarded when his dad ignores him and keeps talking, voice strained in that way Katsuki has learned to associate with holding back tears.

“It’s okay if you’re mad at him too. I would be if your mother did anything like that for me because I would have been scared for her and beside myself with worry,” his father says, not expecting a reply.

His mom speaks up then, her tone much softer now to appease Katsuki. “If you need time away from that green twerp to get your thoughts all in order, that’s fine too. Just don’t let his actions go unnoticed either, you ungrateful brat.”

Katsuki manages a smirk then, an expletive on the tip of his tongue before he stamps it down when his dad shoots him a withering look. “Okay, old hag.”

  Deku stays away as he promised.

Katsuki regrets agreeing to it by the second day. The day after the sludge villain incident, people crowded around him, wanting to know more about what happened. Katsuki had bristled at all the attention, fighting back the urge to let his control on his quirk slip just a little. Just enough to get these shitty extras away from him.

Then some dumbass alphas had to ruin it by posturing and Katsuki sent them to the school nurse. He was not suspended for it, the principal excusing the fight and talking down his nose at him about “traumatic events” and whatever the fuck else the old motherfucker was preaching. Katsuki was much too busy seething at his pity to notice anything else.

He goes back to class and ignores the looks he receives as he walks through the classroom door. He settles down in his desk, casts the projector screen a cursory glance, then decides that taking useless notes isn’t worth any of his time.

Deku’s eyes burn into his back for the rest of the day. Katsuki doesn’t confront him about it, knowing that Deku’s shadowing is the only reason people leave him the fuck alone for the rest of the day.

Everyone knows that they are mates and everyone also knows that while Deku is timid and quirkless and allows others to ridicule him, he switches into high gear the moment insults, violence or slurs are directed at his omega. Katsuki would probably be angry and frothing at the mouth furious about that in another life, but Deku is his mate, alpha, and best friend. If anything, Katsuki expects his alpha to rise up to the challenge. Otherwise, what is the point?

The day Deku stops defending him is the day Katsuki knows Deku is done with him.

So, he is annoyed about his alpha having so much sway, but he is not angry. Not necessarily anyway. Maybe just a little since Deku doesn’t look injured or harmed and barely shows any emotion when people interact with him.

This is why after school the next day, Katsuki rushes out after Deku and catches up to him past the school gates.

Deku doesn’t say a word, just lets their hands intertwine and follows after Katsuki as he leads the way home.

The alpha yelps in surprise when Katsuki takes a sharp right and drags Deku into an alley a couple of streets away from Katsuki’s house. He lets go of Deku’s hand and pushes his alpha against the grimy wall, glowering at him before he closes in.

“K-Kacchan, w-what-” Deku starts to stutter out, back pressed firmly against the wall behind him as Katsuki steps into his personal space.

Katsuki cuts him off with a kiss. He tries his hardest to make it gentle, to try and show everything he can’t say just yet with his mouth on Deku’s.

At first, Deku doesn’t respond. He’s too stiff, pressed back into the brick and arms at his own sides, but when Katsuki starts pulling back, Deku practically attacks him.

Arms come up to wrap themselves around him, a hand burying itself in his hair before gripping on the strands hard. Katsuki makes a choked noise in the back of his throat that Deku takes as encouragement, pulling Katsuki into his space until their chests bump together. Deku’s lips are chapped, but their movements are steady against his own, so Katsuki exhales and relaxes into it.

They pull away for much-needed air a few moments later, Deku flushing a bright red and eyes sparkling with an emotion that makes knots twist in Katsuki’s stomach. His own face feels warm, but his breaths are even unlike his alpha’s and something deep within him preens at the response.

“If you ever pull a stunt like that again,” Katsuki snaps, his voice like a whip breaking the silence. “I will kill you myself.”

Deku smiles at him, pulling Katsuki in close for another kiss. “Okay, Kacchan.”

  Things start to smooth over between them after that.

Katsuki still refuses to talk about stupid feelings when he thinks he can get away with it, but he listens to Deku’s muttered rambling with a small smile on his face that he denies having afterward. His dad teaches him how to cook when he catches him making a mess of the bento box he was going to take for Deku as lunch and he grudgingly learns, picking it up fairly quickly.

Deku smiles at the bento box but picks at the food, only explaining about his new diet once Katsuki explodes at him about not appreciating his hard work, the bastard. Katsuki is irritated with him for not letting him know sooner, but takes note of the new diet anyway and makes a more suitable bento box the next day.

His alpha eats that one without complaint, thanking and praising Katsuki as he eats. Katsuki tries not to let it get to his head and fails.

Their homework and study sessions start ending with Deku pinned down on the floor or against the wall while Katsuki makes a mess of him. Katsuki kisses his alpha as if neither of them is going to get the chance to do so again. Deku barely hangs out with him as is and he is always smelling faintly of garbage no matter how often he showers, so Katsuki treats the time he can get with his alpha as a prize. Something to look forward to.

It’s only when Deku unexpectedly pins Katsuki down one day while they are getting carried away and Katsuki can't push him off no matter how hard he tries that the explosive blonde takes notice of his alpha’s new strength.

“What the shit? Have you been working out without me, you fucking nerd?” Katsuki asks, eyes wide and chest heaving.

Deku’s eyes are dark and his expression is blank, but at Katsuki’s words his features shift and then he’s pulling away, embarrassed. Katsuki sits up once Deku has settled down on the floor beside him, scratching at the back of his head as his gaze flickers across the room but never settles on Katsuki.

“Um, y-yeah! This guy, who’s a personal trainer, sought me out after what happened with the sludge villain and he’s helping me build up my strength for the UA hero course. I don’t know if it’s working well yet, but his training regime is really intense,” Deku flushes, sweat beading along his hairline.

Katsuki’s eyes narrow into slits. “The new diet?”

“His idea too!” Deku answers, smiling nervously.

There are many things that Katsuki could focus on right now. Deku’s new diet, a mysterious personal trainer seeking him out, his new workout and strength, the stench of trash or the fact that Deku is giving him the bare minimum of the truth. Katsuki can tell everything that came out of his alpha’s mouth just now isn’t the real story, but it’s sprinkled in with enough of the truth to not raise suspicion. At least not from someone who hasn’t known Deku since they were in fucking diapers.

Katsuki decides to be merciful - just this once. He’ll ignore the fact that his alpha is being secretive for the time being and play along. But only this once so fucking Deku better be grateful about it when he finally tells Katsuki what’s really going on.

“You’re still gonna apply then?” Katsuki asks, glare trained on the edge of his bed where their homework lays forgotten.

Deku hums, nodding his head quickly. “Yeah! I think my chances are getting better and better each day that I follow this new training plan. I know that the practical part of the exam is going to be a challenge, but I really do think I can pass and so does Yagi-sensei.”

“Deku, what the shit?” Katsuki asks, filing away the trainer’s name for later.

“Kacchan, I’ll be okay,” Deku assures him, turning to smile at him.

Katsuki sulks instead, refusing to meet Deku’s gaze. “You’re an idiot.”

Deku laughs a little under his breath. “Don’t worry. We’ll both get in and then we could be a hero duo like we used to talk about before…”

He knows what his alpha means. Deku doesn't have to say it out loud for Katsuki to remember what happened when he turned four and got his quirk. He and Deku went into an absolute frenzy about how powerful of a hero duo they would make as adults. Deku was practically vibrating with excitement as his own fourth birthday closed in and Katsuki tolerated it, not wanting to be mean to his young alpha.

It wasn’t until they found out about Deku’s pinkie toe joint and his quirklessness that they stopped talking about it. Katsuki still thought of it from time to time though, thinking of other ways Deku could have his back while Katsuki became a pro hero.

He also knows though that Deku would never give up on that dream. And really, who is Katsuki to crush that for him? He’s an omega and the only reason UA allowed his application was because his parents and Deku signed off on the appropriate forms and his mom gave them a piece of her mind through multiple threatening phone calls if they decided to throw out Katsuki’s application anyway.

So Katsuki sighs and leans into Deku’s side. “I never expected you to give up on that dream, you fucking idiot. I just didn’t know you were suicidal.”

Deku has the audacity to laugh. “I’ll be fine, Kacchan! My training is going to pay off, just you wait.”

“Well, I want in,” Katsuki says, half-expecting Deku to tell him no.

But Deku has rarely ever denied Katsuki something he wants. “Sure, Kacchan. Meet me at Dagobah Beach after school, okay?”

Katsuki huffs but nods his head. “Fine, you shit nerd. Now get back to kissing me. Come and show me just how strong you’re becoming.”

Deku’s smile curves sharply at his words and before Katsuki knows it, he’s pinned to the ground with his alpha hovering over him once more.

  Either Deku is an idiot or he knows exactly who Yagi Toshinori actually is.

Katsuki can’t quite believe that the number one hero would seek out his quirkless alpha and decide to train him, but he isn’t very surprised either. All Might had suddenly shown up soon after Deku had rushed to Katsuki's aid when he was trapped by the sludge villain. Deku had also said that he had been attacked by the same villain earlier that day too. Katsuki had heard the dispersing crowd whisper about All Might spending most of the day chasing this villain around, so it wasn’t hard to put two and two together.

Really, Katsuki is honestly just surprised that the number one hero can look this deathly ill and still kick ass when needed.

As much as Katsuki would like to know what the fuck is going on firsthand, he keeps his mouth shut. He sees the way All Might looks at his alpha. It’s the same way his own dad looks at him from time to time whenever he has done something to warrant his father's approval or pride.

Deku’s father not being around would explain a lot of things as well. Katsuki has never met him, but he knows that Auntie is still married to him, that he was an alpha too and that he supposedly had a fire quirk. The more time he spends at the beach watching the two alphas in front of him interact though, the less he believes a Midoriya Hisashi ever even existed.

Katsuki decides to keep this secret guarded close to his chest. He doesn’t want his alpha or Auntie to be thrown into the line of fire just because Auntie married and bore All Might a son. He would never be able to forgive himself if he slipped up and an evil villain with a grudge against All Might decided to take it out on the number one hero’s defenseless family.

But they won’t be defenseless. Katsuki will be there and he would never let anybody lay a hand on either of their heads. Over his dead fucking body really.

He watches Deku move the trash, keeping a close eye on Yagi Toshinori as he thinks of how strong he'll need to be to make sure his birth pack is not harmed.

  On the morning of the exam, Deku stumbles into him at the entrance gates.

He’s sweaty, nervous, and smells like garbage and ozone of all fucking things. Katuski tilts his head at him as he tries to sniff out the new scent but it disappears as quickly as it appeared.

Deku is a stuttering mess and Katsuki rolls his eyes at him, throwing an arm over his alpha’s shoulders and pulling him in close as he guides them to the testing room. Plenty of people stare at them as they pass, probably surprised by the scent of an omega, but Katsuki knows he isn’t the only omega here so he glares at everyone and finds them their seats quickly.

He’ll deny this with all his might, but he is relieved that he and Deku are sitting next to each other for the written portion of the exam. Katsuki always feels calmer when he can hear Deku’s very faint mumbling during a test.

Which is why he glares at some stuck up, tall as shit extra who interrupts Presenter Mic’s explanation on the rules about some dumbass typo then turns right around and calls out his alpha for his muttering. Just who the fuck does this fucktard think he is?

Katsuki mutters expletives under his breath until the start of the written portion, smirking when he feels the fucktard’s eyes on him. Deku smiles at him from the corner of his eye and he smiles back, focusing on answering the questions on his exam after that.

He splits up with Deku for the practical portion and kisses him for good luck, doing his best not to worry about his alpha. Deku has this. He’s been trained by All Might himself for fuck’s sake and he carries those genes in him. Deku has the practical portion under control just as much as Katsuki does.

So when the practical ends and Katsuki calculates his score, he feels smug as he makes his way back to the entrance gates. He’s sweaty and smells strongly of pure omega if the looks from stupid alphas mean anything, but he glares at anyone who looks his way as he toughs it out and waits. His binder is starting to dig into his skin thanks to the robots and being slammed into the side of a building once, but he ignores it and forces himself to take deep breaths no matter how much it makes his chest ache.

His discomfort is completely forgotten about when he sees Deku emerge from the exam building, head low and steps uneven. His usual muttering storm is absent and when Katsuki asks what the fuck happened, Deku stutters out something about a broken arm and legs and zero points. He smells awful, almost something like grief and mostly of shame. It makes Katsuki's hackles rise with anger as a surge of protectiveness overcomes him.

Katsuki walks his alpha all the way home and spends the night after yelling at his mom on the phone for ten minutes. Deku is mostly out of it, not really responding to anything but managing to dress himself in his own pajamas when they get ready for bed. Katsuki ends up crawling into the small bit of space that is left between the wall and Deku’s body on his alpha’s small bed instead of the futon his Auntie dragged out.

It’s a tight fit, but they make it work. Katsuki wraps his arms around his alpha and presses his face into his dark, curly hair, inhaling his scent and hoping that with Deku's head cushioned on his chest, his alpha will be able to come back to. Deku doesn't fall asleep for a long time and when he starts crying, Katsuki only holds him closer and presses his lips to Deku's forehead.

He’d rather die than let his alpha wallow in his own failure. Fuck that crap.

  Deku makes it into UA.

Katsuki is surprised considering how dejected his alpha smelt after the exam, but he doesn’t say anything except for a quiet congratulations and sits through the joint family celebration their birth pack holds for them.

Auntie cries the entire time and Deku looks like he might be on the verge of tears too, especially when All Might shows up in his civilian form and Auntie Inko blushes bright red. Katsuki sees his mom spare All Might a glance before she ignores him, ordering another round of drinks for the adults present instead. Katsuki frowns as his mom orders him another fucking apple juice, but says nothing, much too focused on the way Deku is adamantly playing stupid footsie with him underneath the table.

Katsuki files all that he learns through body language and minute glances at the dinner away for later. Deku doesn’t seem to notice anything amiss, but his alpha has always been pretty oblivious when it comes to social cues so his reactions stopped counting a long time ago.

At least now they can really become a Hero Duo like they always talked about when they were toddlers.

Katsuki is an idiot for running forward when his alpha told him not to. Such a stupid fucking idiot really.

It's bad enough Katsuki got caught up in the dark fog from that misty motherfucker, but now he's fighting back-to-back with Shitty Hair. At least Shitty Hair isn’t awful at fighting and these villains are insultingly easy to handle. Even the stupid chameleon-like one isn’t a match for him.

Can’t these stupid fucking villains fight him like he wants to fight? Or are they all this ridiculously weak? Why did they even bother storming USJ if that was the case?

Whatever. Katsuki needs to find Deku and that stupid Half-and-Half bastard as well first and then he can figure everything else out after.

Katsuki quickly leads the way out of the evacuation site they were meant to train in and they catch glimpses of a fight going on in the very center of USJ.

All Might is fighting some black humanoid figure that Katsuki can’t make sense of, the number one hero at a disadvantage when that misty motherfucker with the teleportation quirk interferes. Deku is running back towards All Might, feet pounding the floor furiously as his alpha moves. Katsuki runs forward before he can really think about what he's doing, growling when Half-and-Half suddenly appears to his right, flanking him. Shitty Hair is to his left, trying to keep up and ultimately failing.

“You, freeze the huge, black one. Shitty Hair, go after the one with all the hands. Misty Motherfucker is mine,” Katsuki barks out orders, hoping with all his might that the betas will listen to him.

He is only mildly surprised when they do, Half-and-Half quickly freezing the monster looking thing as Katsuki tackles Misty Motherfucker. Shitty Hair fails in getting to the leader though and Katsuki grits his teeth, hands warming dangerously on the metal body he knew he would find when he attacked this villain.

Deku stares at him for a moment like a blind man staring at the sun for the first time. It makes something in Katsuki want to preen and say, I can take care of you too. Instead, he bares his teeth with a growl and gathers more sweat in his gauntlet.

It all goes to shit soon after though.

All Might is releasing smoke that is expertly hidden by the steam of the last attack and Katsuki remembers that the alpha had run out of time beforehand. He knows he won’t reasonably be able to do anything but that does not stop him from turning back.

And then Deku shoots forward like a bullet before Katsuki’s very own eyes, somehow thinking that he can do something to help All Might where others can’t. Katsuki makes a step to go after him but is halted by a cold hand on his shoulder.

“Stay,” his beta Orders, eyes glowing gold for a moment before Katsuki obeys.

He doesn’t want to. He wants to kick and scream and go after his alpha, but the omega deep inside him has recognized the Order for what it is. He couldn’t take a step forward even if he fought tooth and nail to break free from the shackles of the Order.

Even still, Katsuki manages to raise his arm and fire a long-range explosion right at the villain covered in hands. Katsuki thanks his alpha once more for a feature he had not thought to add himself when submitting the appropriate papers and applications for his hero uniform as the blast narrowly misses Hand Freak.

The other pro heroes arrive then, Hand Freak gets shot multiple times, and Cementoss throws up a barrier to hide All Might from view as Shitty Hair runs forward.

Katsuki feels the Order slide off him like a wave at that moment and shakes the beta’s hand off of him as he rushes to Deku’s side as soon as All Might has been secured properly.

“You’re such a fucking idiot, Deku,” Katsuki growls as he checks his alpha over, wincing at the broken legs. “And there you go again, breaking your fucking limbs like an overpowered dumbass. Stupid, self-absorbed alpha! What did you think you were gonna do for the number one hero, idiot?”

Katsuki looks up towards Deku’s face when his alpha doesn’t respond, lips turned down in a frown. Deku’s eyes are glowing gold and there’s someone standing over Katsuki’s shoulder, meeting Deku’s gaze while his eyes also glow gold. His alpha blinks, eyes returning to their normal shade of color, face pale as he looks towards Katsuki with a panicked expression. Katsuki only scoffs, rolling his eyes as he tries to get Deku to settle down before he causes himself even more harm.

Fucking Half-and-Half just has to be their mate, doesn’t he? Fucking hell.

Half-and-Half kneels down beside Katsuki and runs a hand through Deku’s hair, scent spiking with surprise when Deku relaxes. Katsuki chuffs under his breath, trying his best to ignore the golden warmth building up in his chest.

The paramedics that swoop down on them soon after disrupt the moment and Katsuki steps back so they can load Deku onto a stretcher. Another medic runs over to them and insists on checking them over for injuries, but Katsuki refuses. He doesn’t want to have someone shoving their hands under his shirt and exposing him to the rest of the class, fuck that.

Half-and-Half allows the medic to examine him quickly as Katsuki continues to argue with them, the beta’s expression kept perfectly blank. Katsuki is almost certain that he’s going to get away with not being cleared by a medical professional until Half-and-Half turns his head towards him and meets his gaze.

His eyes glow gold for the third time today as he Orders Katsuki again. “Let her check you over.”

Katsuki glares at him, moving towards the medic without wanting to. “Stop fucking ordering me around or I will kill you!”

Half-and-Half’s expression doesn’t change. “Midoriya-kun would not forgive me if I did not make sure you were properly looked over and cleared of injuries before you go to see him later.”

“Screw you, asshole!”

This time, Half-and-Half’s expression does change, the corners of his mouth lifting with the promise of a smile. “Maybe another time.”

Katsuki feels his brain stall, appalled that his quiet classmate was capable of humor. “That wasn’t an innuendo, you fucktard!”

“Okay,” Half-and-Half shrugs, not the least perturbed.

Katsuki breathes out through his nose as he turns to the medic, sensing that he isn’t going to get out of this until the Order slips off him again. “In private. I don’t need someone taking off my fucking shirt right here.”

The medic nods and leads him towards one of the idle ambulances waiting near the entrance. Katsuki can see his classmates crowded together, all of them looking perfectly fine, but he ignores them as the medic climbs onto the ambulance and waves him aboard. The doors are shut after him and Katsuki glowers at the medic as she checks him over.

The medic, fortunately, doesn’t comment on the binder she can feel in the top half of his hero uniform and sighs in relief as she gives him the all-clear. He nods his head, jaw clenched, and kicks open the doors of the ambulance.

Shitty Hair immediately approaches him, crowing with happiness about no one getting hurt. Katsuki feels himself growl at that, remembering Deku and his broken legs.

A warm hand grips his shoulder but he already knows from the scent alone who it could be, so he restrains himself lest stupid Half-and-Half fucking Orders him again. The fuckwad. As if Deku wouldn’t rip him a new one the moment he finds out about the Ordering.

But when Katsuki goes to see his alpha after school, he doesn’t mention it. Instead, he lets Deku grip his hand and tells him some mindless story to get his mind off what happened today.

  Deku makes an effort to include Todoroki (as he has insisted on them calling their mate) when they are together.

Todoroki just so happens to always decline.

Katsuki doesn’t take it to heart - he can only guess how ill-prepared their mate must feel - but Deku obviously does. Beforehand, he was okay with the distance Todoroki kept between him and Katsuki, but now that all three of them are mates, his alpha has changed his mind.

He wants to include Todoroki in almost everything they do. Katsuki doesn’t mind it, he’s just growing irritated every time their mate says no. Honestly, Katsuki is pretty sure that Todoroki wants nothing to do with them or the whole mates business either.

He’s sure about this being fact until almost a week after the USJ incident when they are getting changed for another special training exercise with All Might.

Katsuki is in the bathroom stall furthest away from the door that leads to the changing rooms and has just pulled his shirt off when the squeak of a sneaker against the linoleum floor makes him freeze. Slowly, he looks down at his feet and freezes when he finds the Perverted Grape peeking at him from underneath the stall beside him.

“Hey, everyone! Bakugou is a girl!” Perverted Grape yells loud enough for those in the locker room to hear him. “And she has some pretty great tits, too!”

Instantly, rage overcomes him at that moment and Katsuki roars, a loud explosion following the too high-pitched noise that escapes him. The stall door flies off its hinges and hits one of the mirrors, cracking it. Katsuki is too focused on murdering the Perverted Grape to realize that his classmates had run into the bathroom, witnessing him in a sports bra that leaves nothing to the imagination firing off at a streak of purple.

Katsuki freezes again, fear taking him by surprise once he notices his audience. He fights the urge to put his arms over his chest to cover himself up, his explosions dying in an instant.

Then Todoroki is there with a blank look on his face but a hint of rage colors his scent, the only incriminating thing that gives him away. He has a towel in his hands which he wraps around Katsuki silently, eyes trained on the Perverted Grape Motherfucker who is cowering in the corner of the bathroom. Katsuki feels something inside himself stutter, face starting to flush with shame, embarrassment, and a new boatload of anger before Todoroki speaks up.

“Midoriya, if you do not kill that sorry excuse for a hero-in-training for violating our mate’s privacy and misgendering him, I will.”

Katsuki feels his anger spike in indignation, face feeling much too hot as everyone’s gaze is drawn towards Todoroki now. His mate has his gaze pinned on Grape Motherfucker though, something dark and dangerous flashing in his eyes as he waits.

“You came in here to watch Kacchan change?” Deku asks, his voice kept deadly quiet and full of promise.

Grape Motherfucker starts to stutter out an excuse that is drowned out by the loud Alpha Roar Deku lets loose within the next moment. Katsuki shrinks back at the sound, relaxing when Todoroki moves with him, keeping the towel in place so no one is able to stare at his practically naked torso anymore. Deku’s eyes flash gold for a moment, rage coloring his usually kind face as Katsuki watches with a horrifying sense of adoration.

Katsuki is gearing himself up for a murder case involving Deku and Grape Motherfucker before Glasses rushes forward out of nowhere and restrains his alpha. Hundred Arms and Sugar Might come forward to help, all of them struggling with a snarling and furious Deku that Katsuki has never had the pleasure of seeing before. Deku looks beyond reason, eyes flashing gold again as he breaks free of Glasses arms, darting forward to tear Grape Motherfucker apart before he is captured by Hundred Arms instead.

“Midoriya-kun, stop this at once! Violence will solve nothing,” Glasses shouts, his pleas falling on deaf ears. “I already went and got Aizawa-sensei! He was right behind me. Please, stop!”

Glasses’ words do nothing to stop Deku. He only fights harder, almost managing to free himself from all three of the alphas holding him back when a sharp voice cuts through the air.

“What the hell is going on here?”

Katsuki looks up to find Aizawa-sensei standing behind their gathered classmates at the entrance to the bathroom. Aizawa-sensei takes in the scene, eyes darting from Deku, Grape Motherfuker, Katsuki and back underneath his bandages before his hands curl into fists at his sides and he steps forward. It’s clear what has happened, seeing as Katsuki’s status had been made aware to all the teachers, including those that oversee physical activities and Aizawa looks angry enough to strike fear in Katsuki himself. Katsuki’s classmates part to let their homeroom teacher through, everyone now holding their breath as they wait to see what will happen.

“Mineta, gather all of your belongings and report to the principal’s office to await punishment for violating the privacy of your fellow classmate,” Aizawa-sensei announces, looking over his shoulder to spare a bland look at the gathered crowd and ignoring the squeak of terror Grape Motherfucker makes. “Bakugou, Midoriya, and Todoroki, you three stay. The rest of you, clear out. All Might is waiting for you.”

Todoroki’s grip tightens on the towel as he moves in closer to Katsuki, shielding him from the others’ curious gazes as they leave. Deku snarls at Grape Motherfucker when he sprints past him out the door but doesn’t follow him like Katsuki knows his alpha wants to do. Eventually, it is only Katsuki, Todoroki, Deku and Aizawa-sensei left in the bathroom.

“Bakugou,” Aizawa-sensei says then, eyes trained on Todoroki’s back instead of Katsuki. “What happened?”

Katsuki stutters through his explanation, his face and his body feeling too hot as he does. He still feels angry, but now there is embarrassment coloring his mood and a deep pit of shame that makes Katsuki want to blow up an entire building and then some. Deku stumbles into the stall Katsuki was changing in earlier and returns with the shirt he had just taken off before that shitstorm began. His alpha hands it to him as he finishes talking, staying crouched by his side as Aizawa-sensei keeps staring at Todoroki’s back instead of Katsuki.

“I see,” Aizawa-sensei finally says, his voice cold and dead. “I will handle this problem then. In the meantime, you three need to update your forms and information before the sports festival next week. Go to the office after school and do that. You’re all excused from the training exercise today and may remain here.”

“But-!” Katsuki starts to say, feeling like he is going to vibrate out of his skin if he stays still for too long right now.

Aizawa-sensei cuts him off, voice still cold but not unkind. “This is not up for discussion.”

With that, their homeroom teacher strides away and Katsuki watches him leave, shifting with discomfort. Deku lays a hand on his shoulder, looking rattled. His alpha’s smile doesn’t meet his eyes and Katsuki flinches away, hating himself at that moment.

Todoroki’s hold loosens on the towel, shuffling backward to give Katsuki more space. He glares at his beta though, hand flashing out to grab his wrist and stop him.

“You have questions,” Katsuki says when Todoroki finally meets his gaze.

Todoroki shakes his head. “You don’t owe me anything.”

Katsuki scowls at him, taking his shirt from Deku. He twists out of the towel and stands, exposing his stomach, toned arms, and the black sports bra that Deku stares at for a moment before looking up towards Katsuki’s eyes.

“Kacchan, did you wear your binder for too long yesterday?” Deku asks, head tilted to the side in mild disapproval.

“Shut the fuck up, nerd. You don’t have any room to rag on me after what you just did,” Katsuki grumbles, pulling his shirt back on and kneeling so he isn’t towering over the other two anymore. “What the fuck was that anyway?”

Deku flushes. “I told you, Kacchan. I wouldn’t hesitate to go after anybody who insults or threatens you again, especially because of who you are.”

Katsuki’s scowl deepens, but he sighs and fixes his gaze on Todoroki instead, deciding to just rip the bandaid off before Deku can start overthinking anything. “In case you couldn’t tell, I’m trans. If that’s going to be a fucking dealbreaker for whatever the fuck we’re all going to build as mates, you can fuck off right now instead of wasting our time.”

“I don’t have a problem with that,” Todoroki responds, his tone flat now. “I don’t have a problem with either of you. You’re both my mates.”

As much as Katsuki wants to believe him, his recent behavior isn't supporting his claim very well right now. Todoroki must see it on his face because the beta blinks owlishly at him, then sighs and readjusts himself until he is sitting more comfortably on the bathroom floor.

"I had my suspicions on the first day of school. Cis male omegas are extremely rare and I knew that if you were one, you would have flaunted that," Todoroki explains, his dual-colored eyes on Katsuki. "Either way, it's not any of my business what or how you treat your body, Bakugou-kun. It is my business, however, when others think they have any right to disrespect you or other trans folk for simply being that."

Katsuki frowns. "Honestly, I didn't even think you cared enough about either of us to have this kind of thought process, fucking Half-and-Half."

"Kacchan," Deku whines, slapping Katsuki's arm half-heartedly. "Be nice."

"Deku," Kacchan mocks, slapping Deku's arm harsher than the alpha had. "Fuck no."

Todoroki shakes his head, the movement of two bright colors grabbing Katsuki's attention once more. "You are my mates and since I was curious, I did a lot of research during the first week of school. A lot of the transphobia I stumbled upon online made me angry and I told myself I would stay away, but what Mineta did today is unforgivable and I had to intervene, to do something."

Deku grins, resting his chin on Katsuki's shoulder. "Glad to know you agree then. You're having ice cream with us on Sunday and that's not a request."

Katsuki scowls and crosses his arms over his chest. "I'm paying."

"What? No, Kacchan! It's my turn," Deku whines again, hands gripping Katsuki's shoulders as he lightly shakes him.

"You can pay next time. Shut up, you dumbass, overprotective alpha," Katsuki spits.

Deku laughs, the sound light and bright as always. Katsuki finds himself smiling at the sound, only mildly surprised when Todoroki's lips start to curve into a smile as well before his expression smooths over again.

Katsuki looks over his shoulder, finding his alpha has noticed the same thing. They nod, deciding to do something about that.

With time, of course. No need to rush into something so precarious after all.

chapter four of when i fill them, they’ll shine forever 

On the first day of school, Katsuki and Deku walk into class together.

The stuck up extra who called out Deku’s muttering during the written exam is already there and Katsuki leaves his alpha to it when Glasses stands up and apologizes to him. Katsuki feels smug as he watches another alpha praise his after insulting him beforehand. No other alpha has ever done that before as far as Katsuki can remember, so this is definitely a first.

It’s also pretty amusing watching his alpha stutter his way through the conversation, flushing a bright pink as time goes on. Slowly the class begins to fill, but Katsuki keeps his eyes on his alpha. He sits back in his seat, grinning when he sees that Deku is meant to sit behind him and kicks his legs up on the desk. Deku’s gaze keeps flickering over to him, pleading for an escape or mercy, but Katsuki only grins back.

His grin dies when a round-faced, brunette omega enters the classroom and immediately walks up to Deku. Her smile is too bright and he can smell the sugar on her scent, how it’s dialing up slowly as she leans further into his alpha’s face.

The omega in him growls ferociously as his alpha’s face turns from pink to red in an instant, stuttering and stammering too much for his liking. He has to stop himself from jumping out of his seat and scenting his alpha when Round Face thanks him for saving her during the exam and that she’s happy his broken limbs healed well.

Deku starts to yammer out something, but the door opens and their homeroom teacher appears.

Katsuki ignores his alpha once he has rushed to his seat and files out with the rest of class 1-A for the quirk tests Aizawa-sensei wants to hold. Deku trails after him to the boy’s locker room and distracts everyone as he takes his clothes and changes in the bathroom instead.

A few of the shitty extras still stare at him when he emerges, but Katuski ignores them and puts his clothes away in the locker. Deku is waiting for him by the door, changed and ready to go. Katsuki doesn’t speak a word and lets Deku mumble behind him as he leads the way to the field.

There Katsuki gets to show off his quirk in the ball throw and goes back to stand beside Deku, smugness radiating off him in waves while Deku mumbles his praises quietly to him. A grin starts to form on his face until Katsuki remembers he’s annoyed with his alpha and lets a scowl take over his lips instead.

After that, Katsuki is too focused on the tests to care about anything else. He knows that Deku is struggling and growing discouraged with each test they finish, but he forces himself not to care about it. He hates how panicky and unsure Deku became once he was face-to-face with a female omega who didn’t sneer at him.

It makes him feel like he doesn’t matter all that much to his own alpha if another omega can garner that kind of response from him.

He snarls at Round Face’s infinity result on the ball throw and has to hold himself back when their homeroom teacher uses his confinement weapons on his alpha when he steps up to take his own turn. The others must take notice of his anger because a bubble of space soon forms around him and Katsuki growls at whoever dares to side-eye him.

When Deku picks up the ball again and throws it farther than Katsuki would ever fucking believe, he almost storms right over there and demands what the fuck was that from his alpha. Almost.

He remembers who Deku’s father is, remembers that if Deku did have a quirk all this time then it was probably kept secret for the same reason his parentage is. So instead of going over there and giving the alpha a piece of his mind, he growls out, “Stupid fucking Deku!”

Deku looks over at him and grins, pumping a fist into the air. Katsuki almost smiles, but refrains, keeping his glare flinty as he gazes at the shitty extras now staring at him again. He growls a warning and feels a burst of anger in his chest when that does little to deter the staring.

His alpha rejoins him and settles himself comfortably against Katsuki’s side, nursing what looks like a broken finger. Katsuki rolls his eyes and shoves at his alpha’s shoulder, smirking when their classmates’ eyes widen at the action.

“Better stop breaking shit, Deku, or I’m gonna break it for you instead,” Katsuki grumbles, fighting back a laugh as the sound of a collective inhale is heard from all directions.

Deku only smiles. “Okay, Kacchan.”

Katsuki rolls his eyes and continues on with the rest of the test, keeping an eye on his injured alpha. At the end when the results of the tests are revealed and Aizawa-sensei explains that he wasn’t going to actually expel anyone, Katsuki glowers at their homeroom teacher. He knows that he wasn’t lying in the beginning, but it’s also obvious that he changed his mind when he saw that Deku had placed last.

Fucking Deku already living the privileged life of a Pro Hero’s kid.

Aizawa-sensei dismisses them then, handing Deku a note for the nurse’s office. Katsuki turns with the others to follow them back to the locker room when Deku wraps his arms around Katsuki’s shoulders and shoves his nose into his scent gland. His alpha only stays there for a second before he’s stepping back and waving goodbye.

“I’ll meet you at the front gates after school, Kacchan. Bye!” Deku says before he turns and leaves.

Katsuki has half a mind to follow after him and give him a piece of his mind when he notices all the stares, but instead settles for yelling, “Fuck you, Deku!”

Deku laughs and continues to walk away, still dressed in his blue uniform. Katuski grumbles all the way to the locker room and changes quickly, returning to their homeroom where Aizawa-sensei is handing out syllabi. Katsuki takes two and decides to look his over with Deku later when they hang out in his room.

The final bell rings after that and Katsuki makes his escape, not wanting to run the risk of getting caught up in any small talk with these fucking extras. Katsuki saw what most of their quirks were capable of and he finds them lacking.

At the entrance gate, Katsuki leans back and waits, ignoring his new classmates who bid him goodbye. He keeps his eyes glued on the main building so he doesn’t miss the moment when Deku steps out, head held low again.

Katsuki feels a rush of anger thinking of what someone may have told his alpha when he wasn’t around but beats it down. He can wait the few minutes it will take Deku to reach him.

Or maybe not.

Deku has just made it halfway towards the entrance gate when Glasses calls out to him, Round Face running after them while she yells at them to wait up for her soon after. Katsuki feels the anger in him rise up again as Deku goes bright red as soon as Round Face has caught up.

He turns and leaves, not wanting to walk home with his alpha when his alpha doesn’t need him to.

Katsuki makes it to the train station in under three minutes and boards a train, taking a seat and laying back as he looks for his earbuds. Upon finding them, he slips them on and blasts his “angry at fucking deku” playlist he has spent years building. He settles into his seat as the notes of the second song hit him and then frowns as his phone rings.

It’s Deku.

Katsuki answers on the last ring. “What.”

“Hey, Kacchan! Where are you? I’ve been waiting for you at the entrance gates for a while now, but I don’t see you anywhere,” Deku’s bright voice filters through his earbuds.

“I’m on a train home, fucking nerd.”

Katsuki catches the sound of two distinct voices asking Deku what’s wrong and Deku shushing them before speaking into the phone again. “But I thought-”

Katsuki cuts him off, his nerves frayed. “Don’t you have more important people to talk to than me?”

Silence. Such a heavy silence that Katsuki can hear the rumbling of the train underneath him, the murmuring of conversations between passengers in the car. On Deku’s end, Katsuki can’t hear anything except for his alpha’s unsteady breathing.

“Kacchan, did I do something wrong?” Deku asks.

His voice sounds so small and tired that Katsuki immediately wants to run to wherever the fuck he may be and deck him for reverting into old habits so easily. They have both put too much work into Deku's self-esteem for his alpha to fall back into himself like glass.

“No,” Katsuki sighs, the fight leaving him in an instant.

Deku’s voice is steadier and softer when he murmurs, “Okay… I love you. Please let me know when you get home so I know you got there safe. Do you want to walk to school together tomorrow?”

God, Katsuki does not deserve this kindness from his alpha right now. “I don’t know.”

“I’ll ask again in the morning then!” Deku brightens.

Katsuki hangs up and leans back into his seat, watching the scenery go by until his stop approaches. His walk from the station to his house is quiet, his playlist having ended a while ago. He keeps the earbuds in though, wanting to discourage any kind of conversation when he finally arrives home and steps through the front door.

His mom is in the kitchen, already working on dinner and Katsuki kicks off his shoes before joining her. She takes one look at him and sighs, holding her hand out for his phone which he hands over easily. His playlist begins to play again after a couple of swipes from her fingers and then the bluetooth speaker his mom keeps in the kitchen is turned on, his phone connecting with it after a beat.

The volume is lowered only a smidgen, but it’s still loud enough to drown out his thoughts.

They manage to finish the preparations for dinner quickly and Katsuki takes his phone with him when he retreats to his room. He changes and takes off his binder, pulling his sports bra on instead before he looks over the syllabus and glares at the extra one he had grabbed for Deku.

He tries to ignore it but fails and finally gives in.

“I’ll be back before dinner, old hag!” Katsuki yells at the front door while he slips his shoes back on.

His mom waves him out and Katsuki stomps his way over to Deku’s house.

Auntie greets him as he walks in after he has unlocked the door using the key she had given him when he was seven. He gives her a polite greeting in kind, taking his shoes off and setting them neatly beside the others before he walks into the kitchen where she’s working on dinner herself.

“Will you be staying for dinner, Katsu?” Auntie Inko asks with that bright smile of hers that Deku ended up inheriting.

Katsuki only shakes his head, holding up the syllabus in his hand. “No. Just came to drop this off, but thank you, Auntie.”

She hugs him and Katsuki lets himself enjoy for it a brief moment. Auntie Inko is one of the few people who he would ever let embrace him with no consequences. His dad is another and his mom since she rarely ever initiates physical contact, but Deku only ever falls into that category when Katsuki is feeling down or too tired to be angry.

Auntie lets go of him, smiling and running a hand through his hair for a moment before she steps back and turns towards the stove. “Izuku’s in his room, sweetie. If you change your mind about dinner, I can always call your mom. And I can’t wait to hear about your first day at UA this weekend at lunch.”

Katsuki nods, a weak smile on his face as he turns away and walks down the hallway to Deku’s bedroom. The door is open, the curtains drawn back so the sunlight hits his figurines just right at this time of day. Deku is at his desk, muttering to himself as he writes furiously in what looks like a new notebook. Katsuki strides over and slams the syllabus down on the desk, laughing when Deku jumps and falls out of his chair.

“Got you one of these since you didn’t come back from the nurse’s office. That a new notebook, nerd?” Katsuki asks, smiling when Deku looks up at him from the floor.

“Kacchan, you scared me! And I know you didn’t even knock because I would have heard it,” Deku pouts.

Katsuki laughs and pulls Deku up, tugging his alpha with enough strength that they end up pressed against one another, chest-to-chest. Deku flushes once he notices their proximity and Katsuki grins, leaning in before he can think better of it.

Their lips meet in a gentle slide. Deku’s are chapped, but soft and they open for him easily when Katsuki’s tongue prods his bottom lip. Katsuki buries his hands into Deku’s messy hair and breathes in the smell of his alpha, brows furrowing when he smells too much of Round Face and Glasses on him. Deku wraps his arms around his waist and keeps him in place, pressing his nose into Katsuki’s throat when their lips break apart for air.

Katsuki lets his alpha scent him, scrambling to wrap his arms around his neck when Deku bends and picks him up bridal style. His alpha carries them to the bean bag Katsuki bought for him when their makeout sessions became a thing and sits on top of it, rearranging Katsuki on his lap until they are both comfortable. Katsuki pushes his nose into Deku’s scent gland and rubs his face into it, only satisfied with his work when he can only smell himself, Deku, and faint traces of Auntie and All Might.

Deku kisses his forehead and runs his hands through his spiky, blonde hair. He hums a song Katsuki doesn’t recognize but relaxes as the minutes go by.

“Do you want to talk about it?” Deku asks once he has made a mess of Katsuki’s hair.

Katsuki shrugs, knowing that half the reason he came was to get shit off his chest or run the risk of being angry and pissed off for the rest of the week. “I don’t like her.”

“Who?” Deku asks, his head tilted to the side in confusion as he looks down at Katsuki in his lap.

Katsuki sucks on his teeth, arms now crossed over his chest. “That round-faced shithead omega you kept talking to today.”

Deku’s eyes widen for a fraction of a moment before he’s back to looking confused. “Why?”

There’s the question of the hour. Katsuki sighs and settles himself more comfortably in Deku’s embrace, leaning his head against his alpha’s chest where he can hear his steady heartbeat.

“Because of how you reacted to her,” he finally admits, hating the stupid jealousy he can feel gurgling in his stomach. “You’ve never fucking reacted like that when it comes to me, even when I was still dressing like a stupid girl. Do you like her more than you like me, shit nerd?”

Deku sputters above him, his face a bright red once more. “No! She just… She surprised me. She makes me really nervous since she’s so kind to me. I’m not used to people I don’t know very well being nice to me. It kind of felt like I was waiting for her to lure me into some hurtful prank the entire day honestly. Iida I could kind of understand because I’m pretty sure he was treated the same way I was before, but Uraraka-kun just caught me completely off guard.”

“I would kill her if she even dared to think of it,” Katsuki growls, hackles raised again.

Deku smiles at him, running his fingers through his hair once more. “She’s a classmate. You shouldn’t say that, Kacchan.”

Katsuki only glowers at him. “But I would do it. No one hurts my alpha.”

"I know, Kacchan," Deku smiles fondly, leaning down to kiss his forehead. "You'll always protect me, right?"

"Of course, idiot. Not that it looks like you need my protection much anymore," Katsuki scoffs, red eyes burning holes into Deku's shoulder.

Deku sighs, deflating as the bean bag swallows him up. "I'm sorry. I meant to tell you earlier, but-"

"I'm not mad," Katsuki interrupts, frowning at the look on Deku's face.

"Y-You're not?"

Katsuki shrugs his shoulders, still avoiding Deku's direct gaze. "It's for your and Auntie's protection, right? Since you're All Might's son and a fuckton of villains would try using you and her against him, especially if those dumbasses found out your quirk is like his."

Deku blinks, face carefully blank. "What?"

Katsuki blinks back at him mockingly. "Don't be such a shithead. It wasn't hard to figure out Yagi-san and All Might were the same person. You two suck at keeping things casual between you since he looks at you like my dad looks at me. All proud and fond and other emotional crap."

"What?" Deku repeats.

"Don't act stupid, that will make me mad!"

Deku only blinks back at him in shock, seemingly not comprehending anything being spoken. Katsuki sighs and crosses his arms over his chest, waiting.

Eventually, his alpha returns to his senses and tells him the truth. All of it.

"So All Might isn't your biological father then?" Katsuki asks once Deku has finished.

Deku flushes a light pink and shakes his head. Katsuki scowls at him and huffs, "Doesn't mean he isn't like your dad anyway."

"Kacchan," Deku whines. "Stop it."

"Not until you stop denying you're not all father-and-son with each other, fucking Deku. My theory would make for a great cover story though," Katsuki points out, grinning when Deku's blush darkens. "What? Too fucking embarrassed to tell him yourself?"

Deku frowns at him. "Stop it, Kacchan."

Katsuki rolls his eyes. "Fine, but only if you make out with me until I leave."

"Deal," Deku agrees instantly, his eyes darkening as Katsuki's hands slide up and over his chest before burrowing themselves into his hair.

Deku leans down at the same time that Katsuki leans up. Their noses bump against one another but then their lips meet and Katsuki's too busy burying himself in his alpha's scent to care about anything else.

(Katsuki goes home later reeking of Deku and growls when his mom tries to force him to take a shower.)

  Katsuki ends up taking a shower the next morning before he leaves for school. Deku comes up to their door and accepts the rice balls Katsuki's dad shoves at him before he leaves for work.

Deku eats the rice balls one-handed as they walk to the train station, his other hand grasped firmly in Katsuki's own. Katsuki leads the way onto the train and finds them seats quickly, claiming the window seat so Deku can lean on him.

By the time they get off the train and walk up to UA's gates, Deku reeks of Katsuki with only faint traces of Auntie disrupting his alpha's scent. Katsuki feels smug as they walk to class 1-A hand-in-hand. Plenty of other students stare at them, but no one comments on their hands or close proximity which Katsuki appreciates. It's much too early to deal with all these shitty extras and their stupid questions.

When they enter 1-A, most of their classmates are already there including Round Face and Glasses. A hush of silence falls on those present as Katsuki leads the way to their desks, tugging Deku along behind him. He knows that they both absolutely reek of one another and that someone would have to be blind and have a broken nose to not notice the blatant claims they have laid on one another. It's still hilarious for Katsuki to see the bewildered look on his classmates' faces as he, an omega, leads and an alpha follows after him willingly.

Katsuki sits first, only letting go of Deku's hand once his alpha makes a move to sit down as well. That seems to be all that is needed before the silence is broken.

"Midoriya-kun, are you and Bakugou-kun...?" Glasses races up to their desks to ask, trailing off as he tries to think of an appropriate word to use.

Deku looks up from his backpack where he was pulling out his notebooks and pencils. "Oh, good morning, Iida-kun! Sorry if I didn't mention this before, but Kacchan and I are mates."

Katsuki bristles when an eruption of whispers follows. He opens his mouth to yell at all the extras to shut the fuck up before Glasses speaks up first.

"Ah, I see! Well, that would explain a lot actually. Did you have to fill out papers giving your omega permission to enter UA's hero course? I know most schools do not welcome omegas into their hero courses without permission from both the omega's parents and alpha, mate or not. How difficult was the paperwork?" Glasses asks, attention solely focused on Deku now, something that Katsuki does his best not to be angry about.

"Iida-kun," Deku says, his voice serious and eyes dark as he peers up at the tall alpha. Katsuki almost shivers when he catches the bitterness of ozone souring Deku's scent. "Kacchan is right here. Do not speak of him as if he isn't present. That isn't any way to treat your classmates, no matter their sub-gender. You should treat everyone equally."

"Shut the fuck up, Deku," Katsuki growls. "I don't need you defending me or some shit."

Deku turns in his seat and smiles. "I know, Kacchan. Sorry."

"I apologize, Bakugou-kun. I will do my utmost best to treat you and others respectfully in the future. Please forgive me!" Glasses shouts as he drops into a low bow before Katsuki.

Katsuki scoffs, trying not to show how pleased he feels. "Yeah, whatever. Just don't fucking do it again or I'll blast your face off."

Glasses stands up quickly, looking visibly alarmed until Deku laughs then throws an eraser at Katsuki's head. "Kacchan, be nice."

Katsuki catches the eraser before it can strike him and throws it back at his alpha, cackling when it hits his nose. "Shut the fuck up, nerd."

  Katsuki and Deku absolutely destroy Glasses and Round Face during the mock battles.

At first, All Might in his hero form pulls their names out on opposing teams but then grimaces before he switches them around. No one is stupid enough to pit mates against each other in this kind of environment, especially alpha-omega mates.

They become the hero team and easily capture the weapon following Deku's foolproof plan. Except, when Deku's arm breaks, Katsuki almost forgets about their plan and rushes to Deku's side instead.

He doesn't, thankfully, and they win, but watching his mate be carted away to the nurse's office makes him feel sick. Katsuki has always valued victories over anything when it comes to hero work, but if winning means seeing his alpha hurt, Katsuki doesn't want it. He has a lost a number of things because of Deku but Katsuki has never held that against him. Of course, he is competitive and brash, that's really a given. It's just that Deku means more to him than anything - even winning.

Which is why he grumbles and sits in the very back of the observation room with everyone else as they watch the mock battles. He wants to go to the nurse's office and make sure Deku isn't hurting himself trying to downplay the injury or something else as equally stupid. Instead, he has to sit here and watch the stupid fights. Katsuki doesn't pay a lot of attention to the battles, only sparing the screens another glance when that Half-and-Half extra with the stupid hair freezes the entire building.

Katsuki watches him as he returns to the room and their eyes meet as Half-and-Half ducks through the entrance.

He freezes when he realizes that Half-and-Half's eyes are glowing a soft gold.

The motherfucker takes a step in his direction, eyes wide, but that's all Katsuki needs to turn tail and run the fuck out of there, uncaring of All Might's yelling behind him. His trip to the nurse's office is quick but he stops outside the door all the same. The binder in his hero uniform feels constricting enough for him to unlatch it at the side, grudgingly thanking his alpha for thinking of the feature in the first place.

He had wanted a built-in binder without a doubt, but he wasn't all that concerned with taking the binder off if he spent too much time in the uniform. Deku had frowned over his application and sketches before he added the clasp detail and leveled Katsuki with a glare so rare that he did not even think of arguing with his alpha over the addition to his hero uniform.

Really glad about that now as his lungs expand regularly and his breaths come to him normally once more.

He knocks on the door and waits patiently to be told to enter. He needs to see his alpha right now and talk about all the crazy shit he can just feel approaching.

Katsuki can only hope that he won't grow used to visiting the nurse's office because of Deku and fucking One For All.

day four of @bnhaomegaverseweek (hoping my love will keep you up tonight) 

chapter one of when i fill them, they’ll shine forever 

“Wow, Kacchan, your quirk is so cool! I hope my quirk will be as awesome as yours!”

Katsuki keeps her gaze forward, a wide grin spread across her face as Deku allows her to lead. It’s not often that people let her lead, unfortunately. How she longs for the chance though! She would show everyone a thing or two about proper leadership. But she is an omega and none of the alphas at school would ever let her take control. No matter how capable she’s proven herself to be, no matter how much stronger and cooler her quirk is than anybody else’s. 

Well, none of the alphas except for Deku. He always lets her. 

Her alpha always lets her do what she wants. He has never held her back and has never Ordered her around. She has always been the one to take charge between them and he never gets mad at her for it. In fact, if she didn’t know any better, she would say that he wants her to be the one in charge.

She tightens her hold on the large net in her hands and strides forward confidently. “I’m sure it will be, Deku!”

Of course, neither of them know that they’ll be wrong, but they continue onward anyway, smiling as if nothing could ever disrupt the dreams they have built up around each other.

Katsuki has known Deku as long as she has known her own parents.

He’s been a constant in her life for as long as she remembers. Her mom likes showing off the multitude of photos of them in the bathtub when they were babies. Katsuki would probably find it embarrassing if she didn’t still take baths with Deku now. The collection only continues to grow to her dismay, but Katsuki doesn’t say anything.

She doesn’t mind it. Not too much anyway. Deku is her mate and her alpha after all. He likes bathtime with her, so she doesn’t complain.

Even if she feels weird whenever she notices that the bottom half of their bodies aren’t the same, she keeps her feelings and words to herself. It’s something she’s actually quite good at.

Of course, she does explode at school. A mess of curses and bloody fists as she fights all those that try and hurt her alpha or any of the other quirkless kids in their class, but that’s a given.

No one hurts her alpha. No one is allowed to hurt her mate.

She still remembers when they both knew they were mates because it was Deku’s third birthday and when she came over for his party, their eyes met and glowed gold. She couldn’t forget the way the light glimmered on his face and made his freckles stand out so much. She swore to herself after that no one was allowed to hurt what was hers.

Heroes are supposed to protect those that can’t protect themselves and she wants to be a hero.

And she’ll be one. With a quirk like hers, with an alpha that lets her do what she wants, she can do it. She’ll surpass All Might and be number one. Deku will be her support or maybe he’ll take up her offers on training together and become a hero himself. It doesn’t matter if he’s quirkless.

They can do it.

They can do anything if they're together.

 “You’re just a useless Deku! You’ll never be a hero if you’re quirkless!”

“Who the fuck are you calling useless, you piece of shit!” Katsuki yells, running forward to pin the beta to the wall. 

Deku still stands where he was before, pressed against the other wall and trying to look as small as possible. Katsuki has told him over and over again that the bullies will leave him alone if he fights back just once. Just one punch, one shove back, one mean word in their direction to make them back off. Katsuki can’t be the only one holding off bullies for the rest of their lives after all. But she knows he won’t do it. 

He’s too nice, too kind. Too soft and forgiving for any of the crap he gets. And he deserves none of the venomous words spat his way. Katsuki is more than sure of that.

She hates the fear that is wafting off her alpha in waves. It makes her hackles rise and something primal in her howl for blood, to protect, to defend. She shakes the beta in her hold and lets him fall to the floor unceremoniously when he nearly pisses his pants. She knows just how scary she can be when she wants to be, especially thanks to her explosive quirk. People know better than to go after Deku when she’s around, but sometimes, there are the stupid shitheads like this beta. The ones who think they have any fucking right to tell her alpha what to do.

The way Katsuki sees it, if she isn’t allowed to push Deku around, then no one is.

“Don’t talk to my alpha ever again or I’ll make you fucking regret it!” Katsuki yells at the beta’s retreating back, glaring at him and all those around them that stood by and did absolutely nothing, the spineless bastards. “What are you shitty extras looking at!”

The other kids scatter, spooked and terrified of her anger. Katsuki watches them go then turns and takes Deku’s hand. She coaxes him away from the wall, gentle only for him, and leads him down the hall until they enter the playground. They’re both silent as they walk, but Katsuki doesn’t let it remain that way for long.

“Why do you let them treat you like that?” Katsuki asks once they have reached their tree near the edge of the schoolyard. “You know I don’t like it.”

Deku shakes his head and sits between the tree roots, his feet laid out in front of him. “I don’t know. I just freeze up every time it happens.”

Katsuki wants to say something. Deku looks so small at this moment, so lost, and all she wants to do is vow to always look after her alpha, but it wouldn’t be appropriate. She’s an omega and she knows that Deku would never get angry at her for this, but it just isn’t her place. It’s not.

No matter how much she wishes it was.

So she sits beside him instead and stays silent until Deku asks, “I’m not that great at protecting myself, but… You’ll protect me, right Kacchan?”

Katsuki sniffs, trying not to let her pleasure bleed through. “Do you want me to?”

“Always,” is Deku’s solemn answer. 

“Then,” Katsuki begins with a grin that slowly grows until it is spread wide across her face, “I’ll beat the shit out of anyone who tries to hurt you, Deku!”

She pumps her fist into the air to show she’s serious and has to fight back a laugh when Deku smiles at her. It’s her favorite smile, the one he reserves solely for her and her alone. It’s sweet and cute and always makes Katsuki a little nervous to look at, but she keeps his gaze anyway and startles when he leans in.

Deku’s lips are soft on her cheek and only stay there for a moment before he pulls back. She presses a hand to her face and feels it warm underneath her touch. Katsuki hopes she isn’t blushing tomato red like Deku sometimes does. That would be embarrassing and Katsuki doesn’t do embarrassing.

They continue on like normal, but for the rest of the day, Katsuki catches herself subconsciously raising a hand towards the cheek Deku kissed.

 Katsuki holds still as Deku rubs his face into her neck.

He has started to scent her every time they come back from school. The first time, she had held so still she barely thought to breathe before he abruptly pulled away and reminded her.

She knows that the scenting is a form of comfort. That it’s to make his scent lay heavy on her, to drive away other alphas and betas that might be interested. She learned that much from her father when Deku turned six and said he was surprised that Deku hadn’t tried scenting her earlier. She knows what it’s for and that it’s to reassure Deku, but she can’t help but feel uncomfortable.

Because it leaves Deku smelling of her in return, which normally she wouldn’t mind, but she doesn’t like the way she smells. 

Her scent is too floral, too sweet and sugary and makes her insides twist into knots. It makes her want to bury herself in Deku’s scent instead, but that wouldn’t help much.

And, of course, Deku notices how stiff she is, how she forces herself not to react when he scents her. He isn’t stupid. Her alpha is one of the smartest people she knows. How else would he be able to remember so much about heroes and their quirks?

So Deku asks if he can scent her. He always asks and if she hesitates for too long, he steps back and gives her space. He never crowds her and he never tries to force anything. He is always so good to her, even when she feels like she doesn’t deserve it.

Something in her twists and coils at the barest hint of her scent. On some days, she feels sick just being in her body and having to smell herself every second of the day.

She starts showering a lot more often than what is necessary and sprays her father’s cologne on herself in the mornings. It calms her, more than she ever realized.

Deku doesn’t comment on it. He doesn’t press her for answers or asks questions. He simply accepts it as a new part of her and smiles every time she allows him to scent her.

It doesn’t solve everything for her, but it helps. It helps her start to feel comfortable in her own body again and that’s what matters.

 When Katsuki is seven, he knows.

He knows and no wonder he has never felt right. No wonder he hates his natural scent and his stupid long hair.

No wonder he hates his body so much.

It’s the wrong one.

He was born in the wrong kind of body.

 A few weeks after his eighth birthday, he tells Deku.

It has been eating away at him, his alpha not knowing. Deku knows everything about him. Katsuki has never held a secret from him. His alpha has always been his sole confidant. Always.

And it’s about time he tells him. For his own sanity at least. Maybe it will help or maybe it will not, but Katsuki won’t know until he tries.

“I’m not a girl,” Katsuki murmurs, for once on the verge of tears as he admits his darkest secret to his alpha. “I’m not.”

Deku stares at him, confusion on every line of his face. “Then what are you?”

“A boy.”

Deku nods but says nothing. Instead, he taps his fingers on his chin and studies Katsuki like this is the first time he has ever seen him. 

(And well, it’s not like that analogy is wrong.)

“I’m sorry.”

Deku frowns, his confusion growing. “What for?”

Katsuki hates the fact that his alpha is acting so dense. Of course, he has to know what for! Deku is one of the smartest people he knows. He knows Deku knows what he’s talking about.

It’s clear though that Deku is waiting for him to say it. For him to lay it all out there and open up for once.

He groans and rubs a hand through his hair, his fingers twisting into the ends of it now that it is a lot shorter than before. “Because we’re mates and you wanted a fucking girl as your mate, right? And I had to go and fucking ruin shit by being born in the stupid, wrong body.”

Deku’s expression cycles through a myriad of emotions. First anger, then confusion again, then irritation, and then a steady calm that does absolutely fucking nothing to settle Katsuki’s nerves.

“Kacchan, I want you,” Deku finally says. 

Katsuki feels his head snap up in surprise, meeting his alpha’s gaze without meaning to. Deku doesn’t falter, doesn’t let any hesitation or uncertainty slip into his voice as he continues and in the back of his head, Katsuki is grateful for it.

“You can be whoever or whatever you want to be. Don’t let anyone tell you otherwise. Especially not me, Kacchan,” Deku says, reaching out and taking Katsuki’s hands in his own. “I’m not in charge of your body. You are.”

“But, you’re my alpha. You have the right to tell me what to fucking do!”

Deku steps closer. “I am. I am your alpha and I will always be your alpha if you want me to be. But it’s not my place to tell you what to do. I would like to go our whole lives without Ordering you. You make your own decisions for yourself, Kacchan. That isn’t mine to take away from you. It wouldn’t make me a very good alpha and I want to be the best alpha for you.”

Shit, he really is going to cry, isn’t he? Fuck.

“I want to be the best alpha for the best version of you, whatever or whoever that might be. I’m not going to take your free will away, not ever,” Deku continues, his stupid green eyes already overflowing with tears. “You deserve the best kind of alpha, Kacchan.”

Katsuki buries his face in Deku’s shoulder and tries to stifle his sobs, but ultimately fails.

 Later, once Katsuki is sure there is no trace of his stupid tears, he pulls away from Deku’s embrace.

Deku watches him warily, waiting to see if it really is the end of their crying fit. Or Katsuki’s crying fit, at least. Deku never really seems to run out of tears. He has always been a huge crybaby and that alone would irritate Katsuki if he was any other person, but Deku is Deku and Katsuki doesn’t have it in him to find his alpha annoying or irritating.

At least, not usually anyway.

“Do you want to tell Auntie and Uncle?” Deku asks, his voice still warbled by tears.

Katsuki stomps down the heart-wrenching fear that question brings with it and makes sure his voice is steady when he says, “I don’t know how they’ll react.”

“They’ll support you,” Deku says without missing a beat. “They love you.”

“They love their daughter,” Katsuki hisses, unable to stop his voice from shaking and cracking in multiple places as he does.

Deku’s face is still wet with tears, but his voice doesn’t waver and neither does his resolve. “No. They love you, Kacchan.”

Shit. He just finished crying too. Fucking hell.

 Katsuki ends up telling his parents.

They don’t make a big deal out of it and they don’t disown him like he feared they would. Instead, his father goes out and gets him a boy’s uniform for school. Katsuki is wary but wears it anyway.

The first day he goes to school in it, people stare at him. Sometimes it looks like his teachers are going to point it out and say something, but for the most part, people are quiet. They don’t say anything to his face yet that doesn’t mean they don’t say anything at all.

Which is something he quickly learns when Deku gets suspended from school for fighting.

Katsuki storms into his apartment afterschool - spares a moment to politely greet Auntie Inko - and then barges into Deku’s room where he is lying on his bed.

“Who the fuck did you fight?” Katsuki spits out.

Deku sits up slowly, surprised to see him. “Oh! Kacchan, I didn’t think you’d hear about that so soon.”

“Of course, I fucking heard about it! It’s all anyone wants to talk about at school. The stupid extras wouldn’t leave me the fuck alone, asking why you did it and a whole bunch of other shit.”

Deku hums, like that in itself can be an answer, but Katsuki steps forward and jabs his finger into his alpha’s chest. “So why the fuck did you do it, huh? Did you finally snap?”

“I guess you could call it that,” Deku replies, his head tilted to the side as if this entire conversation is difficult. “I mean, I sort of did?”

Katsuki growls, “What made you snap? You’re full of fucking rainbows and sunshine and other mushy shit. What pissed you off so bad you finally fought back?”

“Do you really want to know?” Deku asks, oddly serious.

“Yes! I wouldn’t be fucking asking otherwise!”

Deku smiles at him, like what he just said was hilarious. The little shit. Katsuki exhales and fights the urge to tackle his alpha. He knows how well that would work out and he doesn’t want to be pinned down right now.

Something in him tells him he is going to need space after Deku finally fucking answers him.

“Someone pointed out your uniform and said some things I don’t want to repeat.”

Katsuki freezes, his breath caught in his throat. “What the fuck.”

Deku shrugs. “I know that I’m a pushover most of the time, but something in me didn’t like the way that other alpha talked about you and before I knew it, I had kicked him in the face.”

“What the fuck,” Katsuki repeats.

“Sorry. I probably shouldn’t have done that, but I’m your alpha and I know I don’t really act as an alpha should, but you’re my mate. You’re mine and no one gets to say the kind of stuff about you. Especially not in front of me,” Deku says, his eyes darkening for a moment before he exhales and his usual bright smile greets a stunned Katsuki. “I know you don’t like it when others help you. I’m sorry, but I won’t hesitate to do it again.”

Katsuki watches him, confused and pissed off, but pleased too. Way too pleased actually. Pleased enough to not act on his anger, to not go after that alpha himself, to not fight his own alpha. Beyond the pleasing feeling is something else much more fragile and shy swooping low in his belly.

He just fucking fell in love right now, didn’t he? Is that what the swooping feeling is? Did it really take Deku finally getting violent for Katsuki to admit this to himself? Fucking hell. And fucking Deku and his stupid, gigantic, good heart too! His stupid gentleness and understanding and unfalteringly support. Deku’s dumbass bright smile, the scattered freckles on his face and the way the stupid fucking sun hits his eyes sometimes. Shit.

“You’re an idiot, Deku,” Katsuki finally manages to spit out.

Deku only smiles, his stance beginning to relax as he does. “Yeah. I know.”

chapter two of when i fill them, they’ll shine forever 

Katsuki wakes up to blood spilling between his legs one morning when he is twelve.

He ends up burning the sheets and searing a hole into his carpet once he realizes what is going on.

His mom yells at him about it, but it’s half-hearted at best. Eventually, she sighs and disappears from his doorway before returning with something purple gripped tight in her hand. She gives him the pad and he looks at the stupid flowers covering it, wanting to scream. He wants to kick and yell and bite and cry.

His life is the fucking worst.

Deku catches onto his bad mood as soon as Katsuki has stepped out the front door but he says nothing as they walk to school. Katsuki would prefer it if he did though, at least it would stop him from getting irritated by feeling Deku’s eyes on him the entire fucking day.

Katsuki’s mood drops during the lunch hour when he has to change his pad and almost has a breakdown right there in the girl’s bathroom. He gets a grip on himself quickly though, absolutely refusing to cry in public. When he emerges from the bathroom - double-checking that no one saw him - and makes his way to their usual table, Deku is already there waiting for him.

His alpha still doesn’t say a word as he sits down, just puts a lunch box in front of him and starts to eat from his own. Katsuki feels like he’s going to vomit, but he pushes his rolling nausea down and brightens considerably once he catches sight of the leafy greens, pomegranate seeds and meat that Auntie Inko prepared for him. There are two rice balls as well, but compared to the six that Deku has in his lunch, it’s not a lot. Which is exactly how Katsuki likes it.

He digs his phone out of his pocket and sends a thank you text to Auntie before he begins to eat.

Deku finishes first and quickly packs up his lunch box. From there, it is almost impossible to ignore Deku’s staring.

“What?” Katsuki asks between bites of his rice ball.

“Do you wanna get ice cream with me after school?”

Katsuki blinks, taken by surprise. “No.”

Deku frowns. “But you’re not busy today, so why not?”

“Because,” Katsuki starts with, mumbling the rest of his sentence.

“Huh?”

Katsuki takes in a deep breath and makes sure his voice is steady. “Because I can’t have dairy products for the next couple of days. Or spicy food. Or caffeinated things.”

Silence greets him, allowing him to drown in nervousness, but it doesn't last for long.

“Okay. Let’s go to the store and buy some fruit instead. I bet Mom will prepare it all for us if we ask nicely,” Deku pipes up, one sole finger tapping against his chin. “If not, then it would be a great time for me to learn. I know you avoid chocolate, but let’s get some of that too. Dark chocolate and bananas sound good, don’t they?”

“I guess,” Katsuki mumbles, picking at his food. “I don’t care.”

Deku hums. “Do you need any aspirin? We could pick that up at the store too if we need to. Or I’m sure Mom wouldn’t mind giving you a few of hers. She gets really painful headaches, so she always keeps aspirin on hand.”

Katsuki sets his chopsticks down, glaring at the table. “Fine.”

“Okay, see you later! I need to go to the library and you need to finish eating or Mom will be disappointed. Bye, Kacchan!” Deku says while picking up his lunch box and scurrying away from the table.

Katsuki watches him go, glad for the time alone and the space that Deku is granting him right now. Deku always knows when Katsuki needs something and always gives it to him if he can. It’s just that Katsuki can’t help but feel guilty.

He never knows what Deku needs and if he does, then he never knows how to give it to him. He’s always left bumbling around, feeling useless and stupid. Katsuki understands that he is not a good omega in the traditional sense and that has never bothered Deku in the least, but sometimes, Katsuki wishes that he was a good, traditional omega. That he knew how to comfort his alpha and when to do it.

Maybe their roles should have been in reverse instead. Maybe-

Katsuki stops that line of thinking in its tracks. He doesn’t want to be Deku’s alpha. He wants to belong to someone, to have a place in a pack and have his mate watching his back. He wants to know without a doubt that he will be taken care of and that the same will be expected of him in return.

He doesn’t know what he would do if he was an alpha instead. Well, that's not right either. He does know what would have happened if he and Deku had been born with each other’s secondary gender. He would have fucked everything up, made things irreparable to the point that Deku would give up. Deku would be his hurt and damaged omega and it would be all Katsuki’s fault. Everything would have fallen into shambles, would have broken and never be glued back together again.

Things are better this way. At least if Katsuki goes too far, he knows that Deku will be able to rein him back in easily.

With his lunch finished, Katsuki packs up and makes his way to the library in search of his alpha.

  “Hey, do you want your gift now or in the morning?” Deku asks on Katsuki’s thirteenth birthday.

They’re having a sleepover, sleepy and warm after stuffing themselves full during Katsuki’s party earlier.

Deku had forced him to invite people from school and from the few that actually showed up, they managed to have an alright time. No one was mean or worded things in a way that would make Katsuki bristle with anger. People were nice to his alpha and they even cleared out an hour before Katsuki’s set deadline of kicking them out.

All in all, his birthday was fine. He opened his presents after everyone left and managed to convince their parents to let Deku spend the night. He had pulled out the futon his parents got him soon after he and Deku got too big to share Katsuki’s bed during sleepovers as kids and gave him his favorite pillow. They brushed their teeth side by side in front of the bathroom mirror and Deku changed in the bathroom while Katsuki changed in his room. Deku knocked and waited for a reply before he walked back in and they both climbed under the covers.

Now they are looking up at the ceiling in silence. Katsuki feels tired enough to fall asleep right now but Deku had pulled him aside in the morning and told him that he had a secret surprise for him that he would give to him after the party ended and they got a moment alone together.

“Now, before I fall asleep. We’ll forget about it in the morning,” Katsuki answers, rubbing at his eyes as he sits up in bed.

Deku gets onto his knees and crawls over to his backpack, pulling a long, flat box from it. It’s wrapped in red paper with bombs scattered across it periodically and Katsuki grins at those details before he rips into it.

Beside him, Deku snorts in amusement but doesn’t comment. Katsuki spares him a glance, still grinning and opens the box.

In it is a piece of shiny, black fabric.

“Deku, if you got me a fucking dress, I am going to decapitate you,” Katsuki growls, glaring over his shoulder at his alpha.

Deku only smiles back in reassurance. “Lift it up. Unfold it and you’ll see it’s not a dress. I would never insult you like that.”

Katsuki pulls his lips back and bares his teeth. “It better not be.”

He turns back to the box and picks up the fabric. It’s smooth and shimmery, but not in the way that he expects. When he holds it up in the moonlight, confusion swarms him. He detests dresses and skirts, but a crop top? Seriously? Just what kind of game is Deku playing here? Does he want Katsuki to kill him?

“Did you really wait until we were alone to give me a fucking crop top? Do you have a death wish, you fucking idiot?”

Deku shifts beside him, nervous and twitchy. “It’s not a crop top, Kacchan. It’s a binder.”

The binder falls from his hands and lands back in the box unceremoniously. Katsuki can barely remember to breathe as Deku goes terribly still beside him, the beginning of a mumbling storm already on the tip of his tongue. Katsuki looks at his alpha from the corner of his eye, watching as his face flushes in the dark and the moonlight falls across his hair. Deku's hands twist in his lap, the mumbling storm roaring to life within another instant of silence between them.

“If you don’t like it, I can return it and give you the money I used instead. I just thought you might like it since I overheard Auntie talking to Mom about you outgrowing another sports bra, so I started researching and found out that it’s okay to bind at any age as long as you do it safely. I started saving up then because the good ones are really expensive and I knew a cheap one wouldn’t work and would probably mess with your lungs or something even worse. This one had really great reviews and I didn’t think you would like a full tank top kind of binder, but then I had to wait because they ran out in black and I know you would have hated the other colors available. So then I started worrying that I wasn’t going to be able to get it in time for your birthday, but then two weeks ago, they re-stocked it and I bought it! It came to my house last week and Mom knows because the package got there while we were at school and she opened it to make sure it wasn’t like a bomb or something since you know how paranoid she can be. Which I don’t blame her for ‘cause sometimes villains target random people and it’s better to be safe than sorry, but yeah. She asked if it was for you and I can’t lie to her, so she knows, but she promised she wouldn’t mention it and she asked me if you were thinking about starting hormonal treatment when you’re old enough and I told her I didn’t know. I started doing research on that too and found out you can’t start those until you’re sixteen and only with parent’s permission and only if your doctor isn’t mean about it, which sucks because I don’t think doctors should have that kind of power over people who are trying to be okay with their bodies if they aren’t going to treat those people respectfully and such. I get it if it’s something that would put a person’s life in danger, but I just don’t- Ah!”

Deku only cuts off his long spiel when Katsuki turns and lunges at him. He squeaks in terror and stills as Katsuki throws his arms around him. Katsuki grips him tight, pressing his face into his alpha’s shoulder and inhaling deeply, feeling his eyes burn dangerously.

Another moment passes before Deku’s arms come down around him gently and suddenly Katsuki can’t fight the stupid tears that have been trying to escape him for the last five minutes. He knows Deku starts crying when his alpha sniffs and shifts until they end up lying on the floor, holding onto one another.

Katsuki is quiet as he cries, but Deku tightens his hold on him anyway when he starts shaking and runs a hand through his spiky hair.

“It’s okay. You’re amazing and you deserve to be happy, Kacchan. It’s okay. You can cry. You can be sad if you want to be. I know it hurts, it’s okay. I’m sorry,” Deku chants under his breath, voice cracking multiple times in between sentences.

He almost wants to tell his alpha to shut the fuck up and just let him cry, but the words, his scent, and his embrace are all comforting enough for Katsuki to allow it. Just this once.

Katsuki curls himself further into his alpha and cries himself out, hoping that if he does it now then he won’t do it again when he tries the binder on for the first time.

(He does.)

  “You can go straight home today, Kacchan. I have to stay after school for another talk with the school counselor.”

Katsuki frowns at Deku, raising one brow in silent question.

Deku shuffles awkwardly on his side of the lunch table, gaze stuck on the food that he has been picking at for the last twenty minutes instead of actually eating. “She wants me to consider other schools.”

In the sudden silence that befalls their table, Katsuki’s chopsticks snapping in half seem to echo around them. He’s so overcome with an indescribable wave of anger that he barely notices the fact that his palms are starting to smoke too.

“Kacchan, you’re gonna set off the fire alarm again,” Deku’s voice filters in through the omega’s haze of anger.

“I’m going to kill that bitch,” is Katsuki’s only answer.

Deku sighs, continuing to pick at his food now that Katsuki isn’t in danger of exploding their table (again). “Please, don’t. I already told her that it’s where you’re going and I plan to be with my mate, but she keeps insisting. She wants me to either pick more schools to apply to or apply to UA’s general course instead.”

“She can go die for all I fucking care,” Katsuki spits out. “Watch when you become the first fucking quirkless hero and at a stupid interview they ask about your childhood and you bring up that bitch’s name and this stupid, shitty school. They’ll regret the way they’re treating my alpha like he’s some weak, defenseless piece of shit!”

“I think that’s one of the nicest things you have ever said about me, Kacchan,” Deku murmurs, but there is a smile slowly blossoming on his face so Katsuki can hardly feel embarrassed about his outburst.

“Shut the fuck up, nerd. Go tell her that she can fucking suck it.”

Deku laughs, some of his normal behavior beginning to bleed through. Katsuki pats himself on the back for a job well done when Deku acts like he usually does for the rest of the lunch hour.

Once the final bell rings, Katsuki walks over to Deku’s desk and hauls them away into a secluded hallway where no one will bother them. Deku looks confused and smells nervous, but he calms considerably after Katsuki glares at him then pulls him into a tight hug.

They stand there embracing one another while subtly scenting the other, then Katsuki growls under his breath and breaks away.

“See you later, nerd! Mom’s making your favorite tonight, so you better fucking be there,” Katsuki yells over his shoulder.

Deku’s voice is light behind him. “Bye, Kacchan!”

  “Why the fuck did I have to fucking come and get it?” Katsuki mutters to himself, kicking a can angrily against the alley wall. “Fucking Deku and his stupid shitty taste in food!”

He knows he doesn’t mean it. He’s just angry his homework time is being cut into right now. All because his mom didn’t have the ingredients she needed for katsudon, Deku’s favorite, which Katsuki had angrily texted her about making tonight under the lunch table when Deku wasn't paying attention.

Whatever. As long as it makes Deku happy.

That’s his last cohesive thought before something dark and sludge-like crawls out of the shadows and engulfs him whole.

  After it is all said and done and the stupid heroes have finished ripping Deku a new one, Katsuki finds that he can barely even look at his alpha.

The heroes insist that Katsuki should be looked over by a medical professional, but he’s furious and the last thing he wants to do is take his shirt off in such a public space.

It doesn’t help matters that All Might is smiling and conversing with police and reporters alike, trying to make everything cheery as all hell. It doesn’t accomplish anything except making Katsuki even angrier than before.

Finally, when he is allowed to leave, Katsuki books it. Deku was allowed to leave first and probably decided to not wait up for him, thinking that Katsuki would actually let a paramedic check him out first. Fuck that.

In the distance, a familiar head of dark, curly hair appears and Katsuki kicks it into high gear, screaming at the top of his lungs.

“DEKU!”

He hates how his voice cracks, but there’s no helping it. There is no time either since Deku turns immediately to look at him.

“K-Kacchan! What are you doing?” Deku stutters, face turning bright red as Katsuki advances.

“You’re lucky you’re not dead, you stupid fucking nerd!” Katsuki yells, not caring about how loud he is. “But I’m still going to kill you!”

Deku takes a step back, flushing and stuttering again. “W-What but-?”

Katsuki can feel his hands beginning to smoke and if Deku’s eyes looking down then flickering back up are any indication, then his alpha knows it too, but Katsuki doesn’t give a fuck.

He’s so fucking angry. So pissed off that those heroes were so fucking useless that his quirkless alpha had to jump in to try and save him. They are the reason his alpha thought it was necessary to throw himself into danger and Katsuki was close to blowing his top back in that alley, but in front of his alpha, he can’t keep it together anymore.

See this is the thing. Katsuki isn’t angry that he had to be saved. Well, maybe a little, but it isn't the reason he wants to blow up this entire neighborhood then run back to that alley and beat the shit out of those pro heroes and one sludge villain in particular.

Katsuki is angry because his alpha threw himself into danger that Katsuki could barely handle. He has a powerful quirk, but it did absolutely fucking nothing to stop that villain earlier. Deku is quirkless. Deku is soft and gentle and incapable of not lending someone a helping hand. He’s an alpha, yes, but Deku is so, so fragile. Katsuki knows that his alpha can grow a spine when he fucking wants to and that he can throw a mean punch, especially since they started working out together. Katsuki knows everything about his alpha and that is exactly why when their eyes met, Katsuki was struck dumb with terror because he knew what was going to happen next.

He knew and he was terrified for his alpha.

“You could have gotten hurt, you idiot!” Katsuki spits out, growing angrier when his eyes start burning.

He turns his face away, letting out a deep breath and fighting back the stupid fucking tears. Deku has gone still in front of him. His panicked scent has turned towards confusion and slowly, so slowly that Katsuki can barely recognize it, a growing sense of horror. Both of them do not speak and Katsuki has never felt further apart from his alpha than at this moment.

“You were going to die,” Deku eventually says, finally breaking the stifling silence that had befallen them.

Katsuki feels his hackles rise in defiance and anger again. “You don’t know that! You don’t know shit, you stupid nerd! You had no reason to put yourself in danger like that because of me, Deku!”

Deku steps back like he has been struck, his expression and scent changing quickly. “You’re my mate, Kacchan. I will always do my best to take care of you in any way that I can. Me being quirkless doesn’t change that.”

“That has nothing to do with it! You said I could take care of you, you fucking promised, shithead!” Katsuki growls, advancing rapidly on his alpha with his palms smoking then coming to an abrupt halt as Deku flinches.

Katsuki draws back, looking at the street instead of Deku’s emerald eyes. “I am not more important than you, fucktard. There were heroes there and you didn’t have to do that. Why did you do that? I didn’t need your fucking help and you know that! So why did you run into it anyway?”

He keeps his gaze on Deku’s bright red shoes, his eyes burning fiercer than before. Katsuki does not know what he expects his alpha to say, but it isn’t what he ends up hearing at all.

“You’re my heart, Kacchan,” Deku murmurs, his voice so soft and gentle and Katsuki can’t help the fucking tears that fall down his face then. “That villain attacked me earlier and I almost died. I know firsthand that it might have killed you too. The only thing I could think to myself at the moment was, what am I supposed to do you without you?”

Katsuki feels his head snap up and meets Deku’s watery gaze with his own, suddenly frothing at the mouth angry again. He hates this. He hates this so much and he hates how it’s his alpha who always manages to bring this stupid emotional bullshit out of him when he would rather ignore it all and suffer in silence. But no, Deku has to force it out of him and make him talk about feelings otherwise Katsuki just feels guilty and shitty.

Fuck Deku honestly and fuck stupid ass feelings too!

As if Katsuki wouldn’t have done the same thing. As if Katsuki would not be terrified of losing his mate, alpha, and best friend all in one fell swoop! As if Deku is so fucking noble for throwing himself into danger when all it did was make the situation worse and scare ten years off Katsuki’s life.

“WELL, WHAT AM I SUPPOSED TO DO WITHOUT YOU? This is a two-way street, motherfucker, and you can’t fucking assume that I would ever want you to get fucking hurt because of me!” Katsuki all but screams, shaking and trembling as tears continue to trail down his cheeks.

Deku is much too calm when he says, “I know. I didn’t mean to imply that your feelings don’t matter, but Kacchan… You would have done the same thing.”

Katsuki doesn’t reply, not deeming that statement worthy of an answer at all because they both know it’s the truth. It is what Katsuki was thinking just mere moments before, what he refuses to speak aloud after all that has already happened today.

He is too tired for this crap. He wants to go home and pretend like the world doesn’t exist for a few hours.

Deku must read it in the slump of his shoulders or the dejected look on his face because soon he’s speaking again and giving Katsuki the escape he needs. “If you want some alone time, I can give you space, Kacchan.”

Katsuki can only make himself nod. Deku gives him a gentle and sincere smile anyway, the kind that makes Katsuki want to punch something.

“Okay… and Kacchan?”

He looks up again, letting their eyes meet. Deku looks rattled and tired, but assured too, something that Katsuki rarely ever sees from his alpha.

“I love you.”

What the fuck?

What.

The.

Fuck.

Absolutely not, Deku can fuck right off with that bullshit. Katsuki wipes his face quickly with the singed sleeve of his uniform and flees.

He runs the rest of the way home, crying again, and when he bursts through his front door, his mom is in the kitchen. His dad isn’t home yet, so he ignores her greeting and runs into his room. Locking the door, he lets his tears fall freely.

He feels so stupid and small, something he abhors with all his might. Ugh.

the weight of names

pairing: todobakudeku (bakugou x midoriya x todoroki) 

genre: fluff, angst | soulmate au 

word count: 4000 

summary: izuku gets his soulmark late and bakugou wants to hate him for it. then they meet todoroki and things get out of hand fast. 

part one of marked (ours) 

quirkless.

that is a label all the other kids plaster him with. it hurts, but it hurts more when kacchan goes along with it. kacchan who izuku thought was his best friend.

it isn't fair, but izuku quickly figures out with his face smoldering in the dirt of a playground that life isn't fair. it will never be fair for someone like him.

but he'll work hard anyway because he wants to be a hero. just like all might.

markless.

another label izuku soon figures out will be held against him too. as if his life wasn't difficult enough for him.

kacchan comes into their classroom, boasting about his soulmark appearing the night before and everybody swarms him, wanting to see. it has been years since izuku has been able to call kacchan his friend, but even he can tell that kacchan is uncomfortable, that he doesn't want anybody looking, doesn't want anybody to know who it could be.

their teacher walks in right then and izuku isn't imagining it when kacchan relaxes as everyone returns to their seats and he is left alone again. but he has to be imagining things when kacchan looks over his shoulder and glances at izuku before he huffs indignantly and swivels back around to stare at the chalkboard.

it's strange, but izuku doesn't really care why kacchan looked at him or who kacchan's soulmate is. at all.

but then kacchan stops taunting him, stops shoving him into walls, and cornering him every chance he can get. the most kacchan does now is yell "fucking deku, you nerd!" whenever izuku happens to come within five feet of him.

izuku does not want to know why kacchan is backing off now, yet he knows that it has to do with his soulmark.

other kids in their year start getting their soulmarks too and izuku quickly finds himself at the center of his classmates crowding around him, pestering him with questions about his mark because he's the last one to get it in their classroom. everyone wants to know and maybe izuku should bluff and say that he does have one, but he doesn't want to think of the moment when someone will force him to show it and find only unmarked skin.

so he tells the truth and tries to pretend like it doesn't bother him. some of his classmates feel bad for him, but one boy named asahi - if izuku remembers correctly - laughs cruelly and says loud enough for people standing at the classroom door to hear, "quirkless and markless. you really aren't good for anything, deku."

and then bakugou katsuki bursts across the room and throws asahi into a wall, screaming at the top of his lungs what a waste of space asahi is and how his parents must have cried when he was born because of how fucking ugly is. izuku almost wants to get involved, wants to pull kacchan away from the fight before explosions get involved, but there are no sparks in kacchan's fists and his expression is livid.

izuku sits at his desk, stunned, and promptly pretends like he does not exist when teachers flood in and pull the two boys apart. there's a lot more yelling and kacchan is screaming curses at the top of his lungs and izuku doesn't get it.

kacchan hates him for being quirkless, why would he defend him to such a degree? why would he react this way to someone insulting him when kacchan has insulted him more times than izuku can count?

(izuku knows why he just doesn't want to admit it. not yet.)

kacchan gets suspended for two weeks and asahi one, leaving izuku to deal with all the attention the fight warranted. people want to know why bakugou acted like that for deku of all people if asahi was only telling the truth since everyone and their mother has heard bakugou say almost the exact same thing himself. it doesn't make any sense to anybody.

except to those who corner him and ask him if he's bakugou's soulmate. izuku stays silent and goes home with a heavy heart and queasy stomach, refusing to think about it.

when asahi comes back, he avoids izuku like the plague and practically disappears when kacchan returns.

in homeroom, kacchan glares at asahi before glaring at izuku and then pretends like neither of them exist. plenty of their classmates want to ask bakugou what they have been asking izuku about in the past two weeks, but no one dares. although kacchan still pretends like izuku doesn't exist, izuku cannot shake the feeling that is only the beginning.

he should have enjoyed the quiet when he had it because middle school brings back kacchan's anger, but he doesn't hit him anymore, not like he used to in primary school. kacchan taunts him at every opportunity, cursing the fact that they are both aiming for ua. izuku takes it though, knowing that he's getting off easy when it comes to kacchan.

and then he gets sick enough that he's out of school for three days. after school on the second day, his mother knocks on his bedroom door and tells him he has a visitor.

izuku doesn't know who would be willing to come and visit him, but he tells his mom to come in anyway. she opens the door and izuku almost falls out of bed when he sees kacchan standing behind his mom, a container in his hands. his mom is confused, but izuku gives her his best reassuring smile and sags back into bed when she shuts the door behind her. kacchan hasn't said anything and izuku doesn't know what to do at all, but he guesses trying to figure out why kacchan is here might do some good.

"h-hi kacchan!" izuku squeaks, nervous beyond belief. "what are y-you doing here?"

kacchan scoffs and shoves the container at him, frowning when izuku doesn't move to take it. "brought you soup, you fucking idiot."

izuku winces, already regretting letting his mom leave. "w-why?"

"take the soup before i blast you into little pieces, fucking deku."

izuku takes the container and sits up, feeling his stomach turn with the motion. kacchan steps forward and steadies him, ignoring when izuku flinches at his touch.

"i don't think i'm up for eating right now," izuku pants, nausea rolling through him like a wave.

kacchan still has a hand on his shoulder and izuku panics when it starts to warm dangerously. "what? is my soup not fucking good enough for you!"

izuku flinches again. "i'm going to throw up, kacchan. because i am sick. please don't make me eat it."

"fucking fine! don't eat it!" kacchan shoots back, stepping back to give izuku room. "how the fuck did you get sick anyway, you idiot?"

"don't know," izuku breathes out, trying to will his stomach not to riot against him. "mom thinks it's a cold, but i think it's probably food poisoning."

"it's probably from that thing the guys in math forced me to eat," izuku says in a rush when kacchan opens his mouth to ask how did stupid fucking deku get food poisoning in the first place.

kacchan stares at him in shock for one point five seconds before his hands start sparking and he looks like he is about to explode in the middle of izuku's room. "who!"

izuku stares at him, his nausea now forgotten. "i-i don't know their n-names."

"well, i'm going to grind them into fucking dust. they're fucking dead, do you hear me, deku?" kacchan spits out, practically frothing at the mouth.

"why do you care so much?" izuku whispers, unable to tear his eyes away kacchan's.

it takes kacchan a while for his rage to simmer down into something manageable, but once he does, he glares back at izuku like he's an idiot. "have you gotten your soulmark yet?"

izuku blinks, not understanding what that has to do with their conversation at hand and reeling at the fact that this is the first time he's heard kacchan say something that doesn't include a curse word of some kind. "what?"

"i said," kacchan growls, "have you gotten your fucking soulmark yet or not?"

ah, there's the good old kacchan izuku has known since he was two and a half. "no? i mean, i stopped checking a while ago. every one knows i'm markless."

kacchan starts pacing across his room then, obviously angry and annoyed and a whole bunch of other emotions izuku probably can't even guess, but he still doesn't get why kacchan is here anyway. then he stops and turns around, coming back to the bed to stare at izuku again.

"i'm gonna show you mine," kacchan says, fists clenched at his sides. "and then we're going to check you for yours."

"i don't think-OH MY GOD! put your shirt back on!" izuku panics as he waves his arms in front of him, his eyes shut tight.

"i'm showing you my fucking mark, you idiot," kacchan rushes to say, turning around so izuku has a clear view of his back. "just fucking look, deku. please."

izuku slowly uncovers his eyes, wary and not knowing what to expect.

it's his name across kacchan's shoulderblade. his name written in somewhat neat handwriting and a todoroki shouto that looks more like a scribble on the other side.

izuku feels like he's dying.

but he turns and lifts his shirt anyway, feeling the dread build up within him, waiting for the moment kacchan will explode because izuku is markless. markless and quirkless. the world truly isn't fair.

gentle fingers press against his shoulderblade and the snap of a camera. izuku looks over his shoulder to find kacchan holding his phone out to him, a picture of izuku's back filling the screen. he takes it carefully, breath catching in his throat when he sees the names on his back. names, not one, but two.

izuku isn't so markless after all.

"oh my god," izuku breathes out, handing the phone back when he looks over his shoulder again. "oh my god, kacchan."

kacchan puts his phone away but keeps his hand on izuku's back, right over his own name. "you're a fucking idiot, deku."

"i'm sorry."

"what the fuck for?"

izuku shrugs, reaching for his shirt when kacchan lets his hand fall away again. "for getting it late."

"why the fuck is that your fault, you fucking idiot!" kacchan vibrates with tension, staring at izuku as he puts his shirt back on and turns around. "i should be the one to say sorry."

"what for?"

kacchan grabs his hand and squeezes it tight. "for hitting you. i'm a fucking idiot for doing that."

izuku shrugs, sure that he should be more responsive to an apology he never expected to get. "it's fine, kacchan. i just think i need time. for all of this. and then we can start looking for our other soulmate."

"it's not fine... but okay."

they spend the rest of the day watching all might videos. kacchan goes home before dinnertime and comes back again the next day when izuku is still absent from school. he leaves before dinnertime again with an empty container in his hands and izuku's number saved in his phone.

at school, kacchan starts hanging out with izuku every chance they can get together. word quickly gets out that izuku is no longer markless and kacchan is still angry at just about everything in the world, but he's learning to be kinder when it comes to izuku. kinder, in general, would be better but izuku doesn't want to think about the consequences of the moment kacchan would lose his cool and blast anything in a two-mile radius. this way is easier.

in their last year of middle school, kacchan gets trapped by the blob villain and all izuku can think is not him!

kacchan throws a huge fit about having to be saved by his quirkless soulmate in front of the pro heroes who swarm them as soon as the villain has been apprehended, but afterward, when they're walking back home, kacchan pushes him against a wall and kisses him swiftly on the mouth. he mutters his thanks and then leaves without another word.

izuku starts walking home as soon as his heart has restarted and is so distracted by the kiss that he doesn't notice all might standing in his way until he almost crashes into him. and after that, izuku can't really think straight at all once the training begins.

he spends his mornings with all might, days at school, and afternoons with kacchan to study for the entrance exam. they're both still aiming for ua and kacchan has already told him that he's going to pulverize izuku if he doesn't manage to get in.

all might gives him one for all not too soon after that and izuku is torn between letting kacchan know or keeping his soulmate in the dark. he gave his word to all might, after all, but his soulmate is his soulmate and kacchan will kill him if he finds out from someone other than izuku that he has a quirk now.

school ends and summer begins, but izuku is too busy training and studying to notice that. the entrance exam closes in on him and he forgets entirely about telling kacchan that he isn't quirkless until he's standing in the practice arena with all the other kids trying to get into their dream school same as him.

he saves uraraka in the end and kacchan explodes with fury. izuku tells him everything about all might and his new quirk when he comes to visit him in the infirmary later that day and almost cries when it looks like kacchan isn't going to believe him. all might steps into the room then and confirms his story because he never really expected izuku to keep this secret from his soulmate of all people.

(izuku truly feels like an idiot after that.)

kacchan calls him a fucking idiot, but he walks him all the way home afterward anyway and when he gets his acceptance letter, he lets himself into izuku's home and barges into his room to announce it. izuku smiles and shows him the message from all might about his own acceptance and kacchan kisses him again.

the rest of the summer is still filled with training, but it helps to have kacchan there. izuku is getting better, but he still hasn't used his quirk since the entrance exam.

school starts again and izuku is relieved when he and kacchan both end up in class 1-a. kacchan had gotten there early so when izuku walks in, he's part of the crowd of students who stare at him. the boy with glasses who was rude to him at the beginning of the exam loudly introduces himself to izuku and kacchan is beside him in an instant when izuku tenses.

he looks angry, but that's a constant state of being for kacchan so izuku isn't too worried about it. he stutters out his own introduction to iida and forces kacchan back into the seat he claimed as his own, noting the fact that a boy with two-toned hair sitting in the back of the room looked up sharply when izuku said his name. izuku sits behind kacchan and tries to keep his head down as the other students start talking up a storm, bugging kacchan now.

izuku grabs the back of his jacket when it looks like he might surge forward and start a fight, but the other students catch on and back off, running to their seats when the teacher shows up. roll call brings one surprise.

the boy with two-toned hair is todoroki shouto and he can't tear his eyes away from izuku and kacchan.

izuku doesn't get a chance to talk about it with kacchan until later that day once he's left the infirmary. kacchan is waiting for him in front of the school, looking sullen and confused all at once. izuku takes his hand and they start walking home, kacchan telling him about todoroki walking up to him once the bell had rung.

todoroki wanted to know if they were soulmates, and kacchan had taken his shirt off for all their classmates to see the names on his back. now all of class 1-a knows. izuku winces, putting his arm around kacchan's waist in sympathy as they continue to walk.

they'll have to handle the situation with todoroki somehow, but, for now, trying to get into the swing of things at a new school with new classmates sounds good too.

they make new friends and todoroki doesn't approach either one of them again, but he doesn't stop staring at them whenever they hold hands or kacchan calls him a fucking idiot or even when kacchan brings him a whole bento box for lunch. izuku can guess about half the things todoroki might be thinking about how he and kacchan act and he wants to do something about it, but kacchan tells him to wait until todoroki is ready, to not push things.

and that kind of advice is all nice and good until the villains attack them during a training exercise and they all get separated. izuku has to focus on fighting the villains facing him instead of worrying over his soulmates and almost cries in relief when they catch up to him just as all might comes crashing in to fight a nomu. most of what happens next is a blur but he can hear kacchan's cursing and todoroki's startled cry when izuku jumps to all might's aid to face off shigaraki.

he might break a few bones here and there but at least he and all might and all of class 1-a are alive. that's what counts.

kacchan yells at him while recovery girl tends to his and all might's injuries and goes home when izuku falls asleep.

the sports festival happens soon after and todoroki tells izuku about his father, endeavor. izuku is beyond outraged by the treatment his soulmate has had to go through and he marches them straight to kacchan who explodes right on the spot. they run into endeavor just a few mere moments later and izuku has to hold kacchan back from attacking a pro hero.

izuku convinces todoroki to use the full power of his quirk during their match and takes his defeat with dignity as kacchan yells at them both from up above. later, kacchan will be frothing at the mouth because todoroki didn't want to go all out with him as he did with izuku and unjustly wins first place while izuku watches and laughs at them both for being so stubborn.

they follow todoroki around after that and badger him with questions, trying to get to know him. todoroki endures their poking and prodding and asks quiet questions of his own in return. izuku already considers him a friend, but he knows it will take more time for kacchan to think that as well so they study and eat lunch together and the first time kacchan brings enough bento boxes for the three of them to eat at lunch, izuku kisses him in the middle of the cafeteria.

not a good idea when he catches sight of the look in todoroki's mismatched eyes and he flushes as he returns to his food, letting kacchan yell at him when they are walking home after school. todoroki still treats them the same way the next day at school though so izuku apologizes to him in private and starts holding todoroki's hand whenever he allows him to around school. kacchan is obviously jealous of their progress and decides to one-up izuku by kissing todoroki in the library one afternoon.

todoroki kisses him back, but they never speak of it again and he still won't let kacchan hold his hand.

things are normal for a while until summer hits and more villains attack and kacchan gets kidnapped. izuku is half out of his mind, crying at all hours of the day when he thought he had left that phase back in elementary school. todoroki starts hovering over him, starts actually talking to izuku and asking questions. questions about bakugou, questions about him, questions about how izuku intends to get their soulmate back.

izuku doesn't realize he's been holding out until todoroki calls kacchan their soulmate and suddenly he's kissing him and pulling away to cry again.

he's a mess and rightfully so.

at least todoroki doesn't hold it against him once they've rescued kacchan and izuku ends up being plastered to his side at all hours of the day, anxious to have him out of his sight. they don't get to see todoroki a lot after that and then each other once they begin their internships with a pro hero, but he still shows up anyway when izuku sends him coordinates and they face down stain, the hero killer.

izuku is scared, but no one is going to hurt his friend or his soulmate and he takes his punishment in stride once it's all said and done. apart from their visit from the chief of police, the hospital is quiet until kacchan barges into their room and screams at the top of his lungs about how stupid his idiot soulmates are and izuku sags in relief to see him whole and unharmed but with a weird hairstyle that he wants to run his fingers through and mess up thoroughly. he quiets as a nurse walks in, but glowers at the two of them as iida is rolled away for even more tests.

he waves to his friend and then it's just the three of them.

"you're fucking idiots, the both of you. i've been waiting all fucking night to see you two because they wouldn't let me come up until you'd been moved into the appropriate ward and whatever other fucking bullshit they kept talking about," kacchan growls, the fire in his eyes roaring.

izuku sighs, holding his scarred hand out for kacchan to take. "sorry for worrying you, kacchan."

"i wasn't fucking worried! how could i be when both of my idiot fucking soulmates went and ran off to face the hero killer! i wasn't worried at all, fucking deku!"

"we're sorry, bakugou," todoroki speaks up, his solid voice ringing in the air as he gets out of his hospital bed and approaches izuku's. "but now you how we felt when you got kidnapped."

"so what? this was fucking payback? are you two even more fucking stupid than i thought?" kacchan roars, shaking with his anger and his worry.

izuku takes todoroki's hand and looks at both of his soulmates when he says, "kacchan, it's us. we have no interest in payback. iida was going to get killed and i couldn't stand by and watch my friend die. i wasn't going to let our soulmate die either, kacchan. you know that."

todoroki startles at the casual way izuku claims him as theirs, shifting his feet as they all wait for kacchan's response with bated breath.

"you're both still fucking idiots. who the fuck do you two think you are trying to die on me?"

"we wouldn't do that," todoroki mumbles, his cheeks flushing pink as he reaches out and takes bakugou's other hand. "it's us three or not all. we wouldn't do that to you, bakugou."

"shut the fuck up," kacchan growls back, but there isn't any heat behind it and izuku grins at his soulmates.

he's happy to be alive and to have them both, but he's even happier when kacchan drags him up and kisses him fiercely before turning and doing the same to todoroki. happier when todoroki gapes at him and dips down to quickly kiss izuku when kacchan only glares back and then smirks when the two pull apart.

because after all, it's the three of them or nothing at all.

a gift from us, for us

pairing: todobakudeku (bakugou x midoriya x todoroki) 

genre: fluff, smutty-ish | soulmate au, aged up au 

word count: 910 

summary: "hey, dickshits! it's my birthday!"

part two of marked (ours) 

the party is in full swing.

izuku had been worried about the large number of pro heroes that would be attending, fretting over all the possible things they could break once the alcohol was broken out, but katsuki had told his soulmate not to worry because no one would dare.

(mostly because he had included a threat in the invitations about what fate awaited anybody who decided to break something that his soulmates hold dear. at least it seems to be working. nothing broken so far anyway.)

shouto has been playing bartender for most of the night and katsuki has laughed each time his other soulmate has had to cut someone off, the pained look on his worth hours of entertainment. izuku has been hovering behind him for most of the party, waiting anxiously for something to go wrong, but nothing monumental has happened unless you count sero and kaminari getting on top of the dinner table and stripping to the wild laughter of most of the female pro heroes in attendance.

katsuki doesn't understand the fascination, but izuku had almost had a heart attack when he saw what was happening, so he had to interfere and yell at his drunk friends to get off their table. now he and izuku are in the middle of their living room, watching everyone else dance and have fun.

"hey, fucker!" katsuki yells into izuku's ear, grinning when his soulmate turns to him with a disgruntled frown on his face. "let's dance. give shouto a show."

"you're a menace, kacchan," izuku shouts over the music, peering over katsuki's shoulder to wink at their irritated soulmate in the kitchen manning the drinks.

he only grins, grabbing izuku by the waist as they start to move, gradually integrating themselves deep into the crowd of people dancing. katsuki only stops once they have a clear view of shouto, grinning as the two-tone haired man only raises a brow in silent question.

katsuki only laughs and allows his hips to answer for him instead. izuku is stiff at first, but soon, his hands are on katsuki's chest, mouth on his neck as they grind on another. both of them have their gazes stuck on shouto, so they both see when their soulmate swallows and flushes a light pink before he walks around the table and makes his way towards them.

he can feel izuku's hardness against his backside when he presses in closer, almost moaning as izuku bites his shoulder lightly then holds a hand out for shouto and pulls him into them. katsuki reaches out for his other soulmate and kisses him hard, feeling like a man on a mission once shouto parts his lips for katsuki to explore. izuku keeps a hand on both of them then, his hips canting forward into katsuki's asscrack, leaning even further down until he can press an open-mouthed kiss to katsuki's shoulderblade. exactly where they all know izuku's name is scrawled across in his neat handwriting.

katsuki shivers, moaning into shouto's mouth and forgetting all about the crowd of people in their living room here to celebrate his birthday of all things. so many people. people he never expected to care enough about his birthday to show up even.

eleven-year-old katsuki would cry if he saw how their life had turned out to be now.

friends, family, his soulmates. people he cares about, people he wants to protect.

people he would fight for.

shouto is working his way down katsuki's throat with izuku trailing his fingertips down katsuki's zipper when kirishima starts catcalling them, drunk and happy for one of his best friends, but ultimately gaining the attention of the majority of the people present. katsuki can't even find it in himself to mind much.

instead, he throws his head back and yells at the top of his lungs so everyone can hear him over the music. "hey, dickshits! it's my birthday!"

this is met with a roar of cheers and upraised cups that no doubt filled with alcohol.

"that's why you're all going to get a piece of my delicious fucking cake and leave! i need to bone my soulmates!"

a mix of catcalls and groans rise to respond, but katsuki can't really find it in himself to care much. their bed upstairs is calling them after all.

"oh, my god," izuku groans into his neck, shaking with the force of his laughter. "you're insane, kacchan."

"we have to cut the cake and be good hosts, clean up first," shouto says as the music is lowered to a more respectable volume. "you can't just kick everyone out."

"it's my birthday. i can do whatever the fuck i want, babe," katsuki laughs, grinning at everyone who passes by them to get to the cake that is already being cut into. "and right now, i want to do you two."

izuku thunks his head against katsuki's back. "you're impossible. i don't even-"

"shut up and kiss me, fucking deku. i'm the birthday boy, remember?"

shouto laughs, leaning forward to kiss him lightly before grabbing him by the shoulders and turning him around so he can face izuku. "kiss! kiss! kiss!"

izuku pouts, but he does it anyway. katsuki grips him at the waist and throws him over his shoulder unexpectedly, grabbing shouto by the arm before he starts pulling his soulmates up the stairs. their party guests whoop at them as they ascend and katsuki grins.

best. fucking. birthday. ever.

a/n: please remember that my requests are open!

happy birthday, bakugou! 4/20!
