bakugo katsuki x pro hero sister headcannons ♡

labels. she/her pronouns, y/n is used, reader resembles masaru’s personality.

warnings. light cursing, sibling rivalry/banter, mild violence (sparring), light angst, katsuki being katsuki, occasional soft!katsuki moments, ai used for quirk, light fluff. self indulgent as a older sister lol

as kids, katsuki was always trying to one-up you. if you learned a new move, he needed to master it ten times faster. it was exhausting for your parents, but you secretly loved it.

it started as rivalry—he wanted to beat you. but over time, he stopped comparing and started watching. you were sharp, confident, and strong as hell. and despite how much he grumbled about you being annoying, you were also the reason he never let himself fall behind.

now that you’re both older, katsuki’s picked up this habit of not liking people talking about you in any way that sounds remotely flirtatious. especially if it’s denki. katsuki hates how much denki likes you. it’s hilarious.

❝why the hell was sparky looking at you like that?!❞

❝katsuki. you’re being dramatic.❞

❝nah. he wants to die.❞

people would stop and stare when you two walked down the street. not just because of the familiar fierce expressions, perfect mix of mitsuki’s striking beauty and masaru’s soft features.

your mom teases that you both get that overprotective streak from her. your dad just sighs in the background and adjusts his glasses.

your mom is insanely proud of you. you’re her clone in all the best ways: attitude when necessary, but calculated grace when it matters. she calls you her ❝perfect little menace.❞

your dad is your soft spot. you’re a total daddy’s girl and katsuki pretends to gag whenever he sees you two reading together or fixing up old support gear in the garage.

sunday mornings in the bakugo household are sacred. you and katsuki make breakfast together—him handling the fire, you handling the precision. sometimes you both burn things on purpose just to irritate mitsuki.

your hero name is miststrike, and your costume is sleek, black and with accents of your favorite color, or just all black, with specialized fabric that helps concentrate your mist in high-pressure areas like your wrists and collarbone. katsuki thought it was badass and totally jacked some design elements for his own.

❝…tch. don’t flatter yourself. i didn’t steal that much.❞

❝your gauntlets are literally based on my fog-chambers.❞

❝shut up.❞

during katsuki’s internship with shoto and izuku, endeavor brought you up while training with him. katsuki nearly exploded on the spot. ❝your sister’s quirk is very controlled and calculated. you’re… emotionally driven.❞

❝don’t compare me to her!❞

he does compare himself to you. all the time.

ignition mist is terrifying up close. slippery terrain, no visibility, and then boom—you snap your fingers and light the whole room up.

your quirk has a strange synergy with katsuki’s. you can trap people in mist, and katsuki can blast them once they’re disoriented. in simulations, you two are basically a nightmare to face. one creates chaos, the other delivers the final blow.

katsuki lives for training with you. you don’t hold back, and he respects the hell out of that. even if it means getting sent flying across the training field.

❝i said go full out, dammit! don’t treat me like i’m weak!❞

❝you say that every time, and yet every time you end up with a concussion.❞

❝worth it.❞

sometimes you train at night, just the two of you. the city skyline in the background, the sharp scent of smoke and chemical mist in the air. no words needed—just shared movement and mutual respect.

there was one time you accidentally overdid it and katsuki slammed into a wall so hard he cracked it. you rushed to him, panicked, but he just laughed like a psycho. ❝you finally got serious. damn right.❞

you nearly cried. he still teases you about it.

izuku calls you ❝y/n-nii❞ and it drives katsuki insane. you’re everything izuku admires in a hero—smart, skilled, and kind to everyone, including him. katsuki gets jealous but pretends not to be.

izuku once made a passing comment like, ❝y/n-nii is so graceful and smart. i wish i could be like her.❞

katsuki almost set the common room couch on fire.

❝shut the hell up about my sister in front of my friends, nerd!❞

❝but she’s so cool, kacchan!❞

❝i said shut up!❞

kirishima looks up to you the way katsuki refuses to say he does. he always asks for advice about hero work and battle ethics. you always tell him he’s already got what it takes. katsuki scowls every time.

shoto once compared you to fuyumi and katsuki nearly detonated. ❝my sister’s cooler.❞

you use glasses sometimes, usually while working late or reading hero reports. katsuki has a photo of you in them, but if anyone ever sees it, he will literally combust.

he got his love for loud and classical music from you. you used to blast your playlists in your room, and little katsuki would sit in the hallway pretending he wasn’t listening. now he copies your playlists and pretends they’re his.

you’ve got a soft spot for him, even if you act like you don’t. you’re always one step behind him at competitions, watching from the shadows just in case he needs you. he knows. he just never says it.

he still calls you ❝sis❞ when no one’s around.

katsuki doesn’t know how to say he appreciates you, so he shows it in little ways. like handing you cold drinks after training or silently plugging in your dead phone when you’re passed out on the couch.

he actually listens when you give him advice. he pretends not to. pretends to roll his eyes and scoff. but he hears everything you say. especially when it comes to hero strategy or emotional regulation (which he’ll never admit he struggles with)

you’re one of the only people who can tell when he’s having a bad day before he explodes about it. and you don’t ask questions. you just sit beside him, play his favorite songs, and wait. he always ends up muttering something like ❝…today was bullshit.❞ and that’s your cue to listen.

on your 19th birthday, katsuki didn’t say anything until after everyone left. you were sitting on the balcony alone when he joined you, dropped a wrapped box in your lap, and muttered,

❝you’re annoying. but… you’re the reason i’m where i’m at. don’t get sappy or anything. just open it.❞

it was a new set of gauntlets, upgraded and built to compress mist in smaller chambers. custom-made. you cried. safe to say he cried a little too.

kiribaku x fashion killa’ boyfriend headcannons ୨ৎ

labels. he/him pronouns, y/n used, you be that pretty mofo !

warnings. smoking, suggestive themes, poly relationship dynamics, slight possessiveness, affectionate teasing

• katsuki and eijiro have been together for a while before you came into the picture, but once you did, it was impossible to ignore the way you fit right into their dynamic. katsuki was resistant at first (because of course he was), but even he couldn’t deny how much he wanted you.

• eijiro was the first to bring it up, all casual, like ❝hey, y/n’s kinda hot, right?❞ and katsuki just scowled before mumbling something about you being an annoying show - off with too much money. fast forward a few weeks, and katsuki’s gripping your shirt like he doesn’t want you to leave.

• katsuki acts like he’s the least affected by you, but he’s also the first one to fold when you get serious. you could be sitting back, arms crossed, just watching him rant about something, and the second you tug him close by the collar of his shirt, he’s stumbling forward, face burning up.

• eijiro, on the other hand, lives for your attention. lean against him, pull him into your lap, whisper in his ear — he’s yours in seconds, grinning like an idiot and nuzzling into your neck like some overgrown puppy.

• you spoil them, but especially katsuki. the porsche was a birthday gift, and he nearly blew up the dealership in shock. he tried to refuse, but you gave him that look, the one that said ❝don’t fight me on this, katsuki.❞ now he drives that thing like it’s his pride and joy, even though he’ll never outright admit how much he loves that you got it for him.

• eijiro’s easier to please — he just loves feeling taken care of. he doesn’t need luxury, just your attention and the way you fix his hero costume, making sure it’s functional and stylish. you did the same for katsuki, tweaking his gear so he looked like a menace straight off a runway. they both know you have an eye for it, and they love wearing something designed by you.

• you even added your name in cursive with gold accents on eijiro’s gears and katsuki’s gauntlets.

• you’ve got that effortless confidence, the kind that makes people stop and stare when you walk into a room. streetwear draped on you like it was made for you, jewelry catching the light, cigarette hanging lazily from your lips. katsuki pretends to hate it when you smoke, but the second you exhale near him, he’s gripping your wrist like ❝the hell are you doin’? tryin’ to kill me?❞

• he secretly loves how you taste after.

• eijiro’s more open about it, plucking cigarettes from your fingers with a grin, letting him light one for you just so he can see that spark in your eyes as you looking down at him lovingly.

• they both melt under your touch. katsuki’s all tough guy growls until you have him under you, gasping when you press him down. eijiro is more eager, more obedient, hanging onto every command, every praise you throw his way. they thrive under your attention, your control.

• when you’re out in public, people always assume you’re the tough one. it’s the way you carry yourself — chill, confident, untouchable. they don’t realize the real problem is katsuki until he’s throwing a glare sharp enough to kill when someone gets too close to you.

• jealousy? oh, they hate seeing you get too much attention from others. katsuki’s already possessive, but eijiro’s just as bad — maybe even worse because he’s the type to play it off with a smile before pulling you in by the waist. ❝they don’t get to look at you like that, babe.❞

• your morning routine? lazy as hell. katsuki’s always the first to wake up but refuses to leave the bed unless you or eijiro do. eijiro? dead asleep on your chest. and you? probably scrolling through your phone, absentmindedly running your fingers through eijiro’s hair while katsuki grumbles about getting breakfast.

• speaking of breakfast — katsuki can cook, but he’ll act like it’s a goddamn favor every time. meanwhile, eijiro’s the one hyping him up, throwing an arm around your shoulder like ❝ain’t he the best, babe? look at him go.❞ katsuki just scowls but still slides you the best plate.

• matching outfits are not something katsuki ever thought he’d be into, but now? he’s got coordinated fits with you and eijiro without even realizing it. you’ll hand him a jacket that perfectly complements what you and eijiro are wearing, and he’ll just huff before putting it on.

• he loves it. secretly.

• you are the designated driver, no questions asked. katsuki drives like he’s on a racetrack 24/7, and eijiro’s a little too relaxed behind the wheel. you? smooth, controlled, a little reckless when it counts. katsuki complains from the passenger seat, but you know he likes watching you handle the car.

• they hate when you’re out late without them. katsuki’ll blow up your phone with aggressive where the hell are you texts, while eijiro tries to be chill but ends up sending ❝come home soon, yeah? we miss you.❞ you always come back with a cigarette between your lips, shaking your head at them before pulling them into bed with you.

• the three of you just work. katsuki keeps things exciting, eijiro keeps things light, and you? you keep them steady, make them feel wanted, make them feel yours.

• nights with them are a mess of tangled limbs and whispered i love yous. katsuki’s usually the first to pass out, grumbling something about how you two talk too much, while eijiro just holds onto you like you’re his whole world.

reki kyan & langa hasegawa x ballerina reader ♡

labels. y/n used, she/her pronouns, platonic, feminine delicate reader, canonically shy & pretty reader, professional dancer.

warnings. n/a .

reki & langa were drinking right by a vending machine talking about their plans after skating.

they were honestly thinking of going over to reki’s place to eat, the elder kyan enjoyed company, his little sisters were very fond of langa too.

their conversation was cut abruptly by catching you in their peripheral vision, mind you they have never seen you before. the expression on your face was comedic in a way, a pretty girl with a slight grimace on her face.

the bag you carried on your shoulder looked really heavy too.

little did they know, you were running late to a rehearsal …

you had wired headphones on and your phone sticking out of your bag, the wires got stuck around the straps of the bag and everything fell out. right at the perfect timing, fuck your life.

when i say everything i mean it, down to your 3 pairs pointe shoes, toe pads and spacers, an extra leotard and tights, leg warmers, lip balm, water bottle, claw clip and bobby pins, deodorant, body spray, medical tape, hairbrush, compact mirror, and embarrassingly enough your feminine hygiene pouch.

reki hesitated while langa quickly rushed to your aid, dropping his board in the process. reki adjusted the boards before following langa.

❝i can help you!❞ said the pretty blue haired boy as he knelt down gently placing everything in your bag as reki held it open.

and you let it happen till you quickly realized you dropped something they maybe didnt wanna see, you snatched your pouch containing tampons and panty liners.

❝o-oh sorry, we shouldn’t have touched your stuff without asking!❞ the red haired boy sporting the cutest handband let out. you sighed.

❝i-it’s okay! i just.. im sorry.❞ you mumbled. ❝it’s just the bag is heavy and im running late so if i can j-just grab my things!❞

the two boys snapped their necks and made intense eye contact startling and flustering you a bit like they made telepathy within each other.

❝we can take you if you don’t mind?❞

you thought it about it for a second, felt like hours for them. they could tell you weren’t understanding how they would do it.

❝look, i can hold on to your stuff, and since langa has a longer and a wider board you can grab onto him from behind!❞ and you obliged.

you later found out watergirl was langa and fireboy was reki.

reki would insist on making you custom skateboards, even if you didn’t skate. he’d be like, ❝ c’mon, y/n, you need one just in case! ❞ and surprise you with a board that had an elegant, soft design that totally matched your aesthetic. langa, ever the enabler, would nod and say, ❝ you should at least learn how to stand on it. ❞

❝so you wouldn’t have to hold on to be anymore.❞ whistled out langa as reki laughed hysterically. you huffed.

you did, in fact, try standing on it. it did not go well.

langa caught you before you could fall, but reki was on the floor laughing. ❝ okay, maybe skating isn’t your thing, ❞ he teased, but he still held your hands to keep you steady while langa stood behind, ready to catch you again.

reki thought it was so cool that you were a professional dancer. he immediately wanted to incorporate some of your moves into skate tricks, even though you kept telling him, ❝reki, that’s not how gravity works.❞

langa was a little more subtle about his admiration, but you caught him watching your rehearsals like he was studying every movement. when you asked if he wanted to learn a few steps, he just nodded with that soft little smile of his.

after watching the sleeping beauty fairy variations with langa

❝okay now on this part when after the red fairy leaves, the lavender fairy comes in and you try to lift me.❞ you insisted.

❝okay! w-wait what?❞ langa spurted out in disbelief.

both of them refused to let you walk home alone especially with that big ass ballet bag. reki would be like, ❝how does your whole body not crumble in pieces when carrying this thing!?❞ grunting, langa would just silently agree, already walking beside you as you had your arm intertwined with his without question.

you always had snacks in your bag, and they always stole them. reki would whine dramatically if you refused to share, and langa would just silently take something when you weren’t looking.

reki tried to incorporate ballet terms into skateboarding just to impress you, but it usually ended with him mispronouncing everything. ❝okay, so i just do a… uh, pah-day-doo?❞ ❝reki… that’s not even close.❞

❝reki its pronounced pas de bourrée, its french!❞

when you were feeling shy or overwhelmed, langa would casually place a hand on your shoulder, grounding you. reki, on the other hand, would be extra loud and silly to distract you from any nerves.

reki loved drawing little doodles on your hands with his marker. sometimes they were random, sometimes they were little messages like ❝you got this!❞ or ❝remember to eat!❞

if you ever had to dance in front of a large crowd, they’d be front row, cheering way too loudly. joe and cherry would have to remind them not to scream your name in the middle of a routine.

❝gosh! of course they would put the spotlight on her, she’s the most beautifulest ballerina girl in japan!❞ reki whispered yelled.

❝beautifulest isn’t a word stupid!❞ miya remarked him smirking. all langa was doing was remembering when you could whine how hot the stage lights would be while hitting you during dress rehearsals, as his jaw was on the ground.

cherry had to scold them and miya during intermission before the next act.

you tried teaching them a simple waltz one time. langa actually did well, but reki? absolute disaster. he kept stepping on your feet, apologizing every two seconds, and then laughing too hard to continue.

you had a polariod of reki and langa simultaneously lifting you in your swan queen costume in the back of your phone, taken by yours truely, langa’s mom, nanako hasegawa.
