Hello. Do you write for x oc?

no sorry! i only write x reader, however i can give the reader specific personality traits and and backstory information that could resemble your oc, but i’d still keep name and appearances vague!

[cerebralinvasion]

wip anon here!! i was so worried i lost your account haha!! what inspired the name change though? :)

i originally chose angelsite because i wanted something more unique… and later i realized it really wasn’t at all unique and was taken on almost every platform, so i decided to actually check this time and chose something that would help keep me at least a little distinct and recognizable so i could be able to stay consistent throughout different platforms!

[cerebralinvasion]

yandere october 2023 event day 2

“lock”

you were not a criminal. despite your many faults, it was one of the things you could be confident in. of course, you wouldn’t say you’re the most innocent person on earth nor that you were any kind of saint, however you were, at the very least, not a criminal. and certainly not on any level that would cause the hunting dogs to be after you. so why were you being treated like some kind of terrorist?

innocent civilians don’t get chained up and monitored by a member of the military. so maybe there was some sort of alternative explanation. one that an ordinary person like you wouldn’t automatically think of. one that would make more sense. maybe you had been framed. framed for something really, really bad. so bad that the government didn’t even want to risk taking you in normally and had to come in and abducted you like this. once you could talk to that military officer you'd seen, you could explain everything to him. it would all be annoying, sure. having to wait through a trial while you proved you weren’t guilty for… whatever this was would be a terrible waste of time. but at the very least you’d get out of it relatively soon. maybe you would even be compensated for the emotional damage.

thoughts like that calmed you down. they always did. coming up with rational explanations of the irrational and unexplainable never failed to mollify you in stressful situations. with a few deep breaths, your heart stopped racing and you were done panicking. all you had to do was wait for him to talk to you and you would explain everything.

you didn’t have to wait very long.

you had no more than a total of twenty more seconds to yourself before the silence was broken by the sound of a door creaking. you shifted, turning your body in the direction of whoever had entered the chamber that laid somewhere between the line of a bedroom and a cell. his presence was overwhelming. he was tall, and you being seated on the ground did nothing to help how he loomed over you. despite how his eyes remained closed, you could tell all his attention was hooked on you, all his senses piercing through your soul. your breath hitched. all the words you had been planning out left your mind and you felt yourself freeze.

“hello” he smiled at you when he spoke. a smile far softer, far more dissarming than it had any right to be.

like a deer caught in headlights, you couldn’t bring even your mouth to move. instead you stared up at him with wide eyes. too scared to even attempt to respond. all the calming yourself down had been for naught, it seemed. because just looking up at the man had sent you right back to square one.

“no ‘hi’ back? that’s a little rude, don’t you think?” he tilted his head just barely. an action too innocent for someone so innately threatening.

your mouth opened and closed repeatedly but no sound came out. you tried your best to mold your words into some kind of apology, but you just couldn’t manage. he noticed this and laughed at you.

“seems you're a little worked up. not to worry, you’re safe here.”

“i’m- i’m not a criminal!” finally your mouth gave way to movement and you managed to blurt out the words.

“i know that.” he didn’t miss a beat before the words fell from his mouth.

and suddenly you were cold. because with only three words he had thrown out any little bits of rationalization you had managed to scrounge up. you were back to square one with no idea as to what was happening. not an inkling to the man’s motivation or intentions.

then he smiled as if he could read your mind. a knowing edge clung to the faint smirk which was smeared across his face.

“you’re not a criminal, and thus you’re not being detained. do you know what that means?”

his grin widened as he leaned down, closer to your level but still towering above you. after a short beat of silence he continued.

“it means that even the law can’t save you from this prison. there will be no proving of your innocence, because i already know you are innocent. you aren’t here for legal affairs, no, this is… personal.”

“personal? i don’t even know you!” your voice betrayed more of your genuine fear and uncertainty than you’d have liked it to.

“then how about we change that? because i know you, very well in fact.” he gave the words a second to sink in and for you to reach your own conclusions. “you may call me jouno. from this point forward, you’re officially mine.”

RENTAL S/O DARLING OR RENTAL BOYFRIEND DAZAI SJSHHDJSMDNDH

remember when i said i would write this like 5 months ago….maybe ill do rental bf dazai next...

this is not an accurate portrayal of how partner rental services work ^^ just for a work of fiction :>

cw: yandere character (dazai), implied stalking, obsessive behavior, dazai is deluding himself a lot

if you find him strange, you don't let it show.

he supposed this act of yours sold well; perfectly unassuming and a touch shy, all cute smiles and gentle brushes. even he has to admit it's flattering, but he knows better than to fall for a front. you hold his hand and ask him what he likes to do; safe questions, about his day and his favorite food, if he watches any shows or if he's played that popular game everyone’s raving about. his answers are honest, even if a little unusual. you don't bat an eye at his whining about how difficult his job—intentionally obscuring details otherwise—is; how they work him to a bone and he has no time for anything. when he leans into you and pouts about how mean his colleagues are for always making for of him, you only laugh and say that it must be because his expressions when he's upset are undeniably adorable. it's not the answer he expects, and he falters for a moment, as you giggle again at his shock. you're good, he thinks, fun and easy to get along with. if he were anyone else, he would have already fallen for your quips and grins.

but he knows very well what he's paying for.

you don't seem all that concerned about his more eccentric comments, and even if he’s certainly far from your usual customer, you treat him as well as you’d treat your other clients. he’s watched enough of your ‘dates’ to know that by now. you roll your eyes at his terrible flirting, but smile as though you’re smitten. you pretend to be upset when he steals spoonfuls of your dessert, but never move your plate away. you let him lean on you when he complains about his feet hurting, even if it makes for an awkward position.

it would be so easy to fall for someone like you. someone so perfect; a fantasy of a perfect relationship. lovely dates to indulge in after a exhausting week. a small escape from the painful mundanity of life.

you send him off with only a squeeze to a hand and a word of gratitude. it isn’t much, but his hands tingle and he wonders how much it’d cost to get a kiss on his cheek instead.

he’s not of your usual crowd of lonely salarymen and awkward students, and you likely don’t expect him to come back. but he shows up a week later, and you greet him with that same bright smile.

“thank you for making time for me,” you say, and to any onlookers, this might appear like a perfectly ordinary date. apart from a curious look, nobody acknowledges the two of you, likely out of consideration. but dazai knows the people here were well aware of your job, likely having seen you around. only he could pretend this fantasy was anything more. 

“the atmosphere is off,” he claims, before asking you to go to the countryside for a change, knowing well how ridiculous the demand was. it’s a pathetic reason for a equally pathetic attempt at satiating a desperate need to be with you. 

again, he tells himself that it’s not because it’s you. he just wants to know how it’d feel like; to be loved, and to be in love; the gentle, soothing kind. all the things that dazai knows to feel are vicious and intense, and nothing like the tenderness you offer. he wants something to alleviate his greedy heart, if only for a moment, and you just happen to be willing to play your part.

after excusing yourself for a few phone calls, you inform him that the countryside is too far for a day trip, and suggest other places instead—all bustling with people, and nothing like the remoteness he’d have liked, though he smiles and takes his pick regardless. on the train, he stands too close to you, but you continue the conversation without faltering. you've always tried to accommodate him, and not entirely because you have to. last week he heard you tell a friend over the phone that he reminded you of a cat, with how he jumped from overly clingy to quiet, and he took it as a good sign.

still, exploring the city with his hand in yours is far more delightful than he’d hoped. he preens at the envious looks he receives, and happily eats up the comments of how cute the two of you look together. the two of you struggle over directions together and navigate congested streets, and you even agree to share your ice cream with him. you grumble about the heat, hair sticking to your forehead, and dazai eagerly blows right at you, making you scowl and bat his face away. but you’re laughing right after, and he’s smiling like a lovesick fool. he takes care to imprint the sight of you, grinning with your hands sticky with melted ice cream shielding your face, in his mind.

“i want to go to an amusement park next,” he whispers, ignoring the displeased look he gets from everyone else on the train.

though you poke his side in response, you still nod, and you don’t move away when he leans his head on your shoulder. as always, your hand is around his with a reassuring squeeze. he squeezes back. he thinks that he likes the weight of it—familiar and real. he closes in eyes to take it all in, to memorize his pounding heart and your warm hand in his, the scent of your shampoo and the way your hair brushes against his cheek.

but he'd like more—greedy as he is—and as the pricing for next week goes up, so does your proximity. you naturally ease into calling him osamu and baby, and even the ridiculously cutesy nicknames he demands for without a single moment of hesitation. you comply with all the cliches he wants, letting him feed you and brushing away the tiny spot of cream at the corner of his mouth (ignoring how he had just smeared it there himself), easily catching him when he stumbles and offering him your jacket when it’s cold. the most he gets out of you is a raised eyebrow at some of the more startling requests—when he asks for you to refer to him as your superior on one date, or when he asks you to wrap new bandages around his arms, but you never say anything else. you never make him feel like it was anything but ordinary.

it’s a shame he can’t get anything more intimate, no cuddling or kisses—at least not the kind he wants, with your mouth on his and your hands in his hair—but he can find other ways to make up for it, even if at this point, the idea of playing pretend leaves a bitter taste in his mouth.

two months and eight dates in, he asks you to fight with him.

you shoot him a wary look, “i don’t know how. though if want to go see a fight—"

you've let your guard down a little by now, and dazai finds that he likes this side of you more than the facade you put on. you're still terribly warm and polite, but your smiles are less practised and your words less polished, your eyes brighter and your movement less stilted. you're becoming comfortable around him, unbeknownst to yourself. dazai relishes in the fact—maybe another month would be all it takes for you to drop the act completely.

"no," he says, "i want us to fight. like couples."

"like couples?"

"you know, argue about buying the wrong groceries, or about forgetting birthdays. that sort of thing."

"is it your birthday?"

he considers saying yes, just to have something to whine about and have you try and appease him, but ultimately decides against it. "no."

you stare at him, still unsure of what to do.

"you were late again," he starts, "it's the third time this month."

he has to bite back a smile at your blank expression.

"i'm sorry...?"

"don't say it was because of work again. i won't buy that excuse any longer."

you nod at how he harrumphs, finally catching on.

"i'm sorry, honey. i really need that promotion."

he shoots you an accusing glare, "is that the reason? or is it because of that coworker you keep hanging around?"

"you know i don't care for anyone else," and your eyes soften, "it's only you."

he pouts, but lets you grab his hand from across the table and squeeze it. he can't think of anything else to say when you're looking at him like you're so endeared.

it's only an act, he knows. but to what extent?

"i like you," he admits when you see him off at the station, "i didn't mean to—i know i shouldn't"

he can't remember when the revelation occurred to him. but somewhere during those dates, he realized it wasn't just a simple kind of love he was craving. it was something more, and something that you were fundamentally part of. it was your laughter he wanted to hear, and your hands he liked the weight of, you he wanted to hold and your love he wanted to feel. his voice is weak enough that he hopes, for a second, that you don't hear him after all. but your eyes are always on him when you're together, and there's no taking it back anymore.

you don't reply, lips pursed together. your eyes look dull, and he wonders if you've been hiding how tired you were to not disappoint him. you watch him board the train with a pensive look on your face. dazai understands; it was a sudden revelation you probably had not been expecting. but you'd come around, he's sure. you were already starting to blur the lines between you and the persona you played. you've mentioned that you think he's funny, that you think he's cute. that must mean something, right?

he finds that he's been blocked from the website the next morning.

he's not entirely sure why—was his confession that frightening? or was it just what you had to do, for your job? maybe it wasn't even up to you. he tries again from an internet cafe, but the minute he keys in his card information, he's kicked off the site. he considers taking kunikida's card for the booking instead, but he would be livid, and...the thought of you getting ready for anyone else made him sick to his stomach. was he supposed to watch as you put on your kind smile and wait for kunikida instead?

fortunately, he knows your habits well enough to plan a meeting with you. while your work hours were inconsistent, there were other things you did regularly—grocery shopping on thursday evenings and dinner with your friends on saturdays. he could work around that, coupled with listening in on a few calls.

he lies in wait outside the convenience store you frequent, running over all the things he'd like to say to you in his head. should he apologize, or pretend like nothing had happened? maybe he should ask to explain things over a drink, or just beg you to hear him out.

you stop walking when you catch sight of him, and you look more irritated than upset. your mouth is twisted in a scowl he's never seen before.

he's certain of it now—this is his only chance. and it's obvious you weren't going to sit and listen.

perhaps a small part of him had always known that it'd never work out the way he wanted. it would be easy, he thinks, to just take you. you could change your mind about him later, but at least you'd be with him. he should have known he wasn't the kind of person deserving of sweet words and slow kisses. dazai had only ever known to be cruel, and perhaps this was all he could ask for in return.

he's pretended that you loved him for months—what would letting it go on for a little longer change?

However, Ozaki does not want to let go of the reader, and will tries to find a way, to force the reader to stay in mafia. Gender Neutral reader is fine.

return to sender.

yandere koyo ozaki x reader.

notes: sorry for being gone so long everyone!! im backkkk

tags/warnings: yandere, brief mentions of god, threats but no violence really

the life you had chosen wasn’t an easy one. of course you had known that going in. no one joins the mafia thinking it was going to be cupcakes and rainbows. but maybe you had underestimated how brutal your life would become. or maybe you just chose to ignore it. chose to lie to yourself that it wouldn’t be all that bad, do whatever you could to make the money you desperately needed. it was difficult, of course. working by the higher ups was terrifying. you constantly feared for your life, even around those you were supposed to consider allies. you never truly felt like you fit in where you had come to find yourself. the people around you felt dangerous in a way you were not. whether they worked above you or on your level, you felt like an oddity. someone whose mind just wasn’t strong enough for this life, not the way theirs were.

there was only one person you had come to find comfort in: koyo. as an executive her position was held second only to the boss. from her status, to her fighting skills, her wits, and her supernatural ability— she was superior to you on every level. she had no business with a low-life grunt such as yourself. yet somehow, despite all odds, you managed to peak her interest. you don’t have a clue what it could have been. what you possibly could have accomplished for her to take you under her wing like she did, but it worked. you’d managed to garner her favor.

it was a lot different now than it had been when you two first interacted, all tense shoulders and short responses on your end. trying to make yourself as small as possible and avoid catching her eye. that’s changed. you wouldn’t say you had ever become at ease in her presence, however you did lose much of the initial terror. out of everyone in the mafia, you could easily say you preferred to spend your time with koyo.

but it wasn’t enough. having a single person you could semi-trust just wasn’t enough to convince you to continue like this. to continue staking your life every day for profit. putting everything you had in terrible danger and trampling your morals for some extra cash.

finding your way into the mafia had been hard, and you knew that finding your way out would be even harder. but you had to try. you refused to lay down the rest of your life for this. naturally, it’d be dangerous. but no more dangerous than engaging in shootouts on a regular basis. no more dangerous than spending your days around seasoned killers.

the plan was simple. make yourself as little of a threat as possible. you wouldn’t turn to the government or anything of that nature. you figured that if you made it clear enough that you wouldn’t be any harm they wouldn’t even bother looking for you. you know people have done it before, maybe you could be one of them. it’s not like you were a noteworthy asset. you weren’t an executive or a leader of any unit. you were just another faceless grunt. the odds that anyone would not only notice but also care were slim. you didn’t have access to highly classified information. you would make a pretty useless traitor.

on the night of your departure you worked quickly. packing everything necessary from your apartment into a rather large suitcase. you withdrew the money from your bank account and found your way to a mediocre hotel until you decided where you’d go. but just as you were preparing to settle in for the night you heard a knock on the door. it had to be near 4am, what was room service doing at this time of night?

the second you twisted the door handle you were flung back. something had hit you, hard. there was little damage, but you could already feel an aching sensation bloom along where your head and back had made contact with the wall. you looked up. there was a blade at your throat and a woman a few feet ahead of you. you dared not move. not when a literal demon held a short sword centimeters from your jugular.

“now what do we have here?” elegant as ever, koyo strode further into the room, making her way to the wall opposite the door, where you were pinned into place by the golden demon.

“koyo….” your mouth instantly dried up when you heard her voice. “how did you… find me?”

she laughed.

“did you actually expect to simply waltz out of the port mafia? you should know better. i really did think you were smarter than that… you didn’t even bother leaving the city.”

“it hasn’t even been six hours since i packed up… i got to the hotel less than an hour ago! how? how did you get here so fast?”

koyo’s movements were near serpentlike as she brought her own shortsword up to your neck, taking the golden demon’s place. the ability moved behind her in a defensive position. it floated ominously, it’s mere form acting as a barricade from the door. no one would be getting in or out until koyo removed the thing.

“you really should break this habit of underestimating the opponent. of course i found you. maybe the hope in your heart came with a heavy dose of naivety. hope that things would work out for you in a way they didn’t back with the mafia. you should know by now that god is no longer on your side, not after all you’ve done.”

your breathing stuttered. she was right. you never would have rushed into something with a plan as rudimentary as ‘just hope the enemy won’t notice’ back when you were with the mafia. only a cruel hope could produce such utter stupidity.

“still, to think you’d disappear without so much as a goodbye? not even to me?” koyo tapped the blade against the underbelly of your chin, watching as you tilted your head upward to avoid it.

“don’t… don’t kill me. please just let me go. i promise, i swear on everything, i won’t tell anyone anything. please.”

“now, you know i can’t do that, right?”

your breath quickened. was this it? the whole plan was stupid and half baked in hindsight, now it seemed you would pay for your lack of foresight with your life.

you weren’t ready to die.

“poor thing… you’re trembling. really, just how far did you think you’d make it? no offense, dear, but there’s no way someone like you could make it out of here. you’re no osamu dazai, you know? pitting yourself against the port mafia is a losing battle. you’d be crushed like a butterfly in the beak of a hawk, and wouldn’t that be unfortunate.”

“i just don’t understand… why would an executive like you be sent to fetch someone like me?”

“sent? oh no, you misunderstand. nobody sent me to come get you. in fact, no one else even knows you tried to leave, not that they wouldn’t have found out within the week... but tonight? consider this a… personal endeavor.”

you furrowed your brows. the more questions she answered the more confused you became.

koyo pulled the sword away, neatly tucking it back in it’s holster. the blade once again masqueraded as an elegant parasol. demon snow fizzled out of existence. she reached the hand not gripping the wagasa towards you. offering a hand to help you up.

“now then, let’s go home before you cause any more trouble.”

yandere october 2023 event day 1

“needle”

there were very few things you feared. it was natural, as a member of the port mafia you grow desensitized to death and violence. things that would scar most for life become everyday occurrences for you. however, there was one fear you did retain. it was menial and mildly embarrassing in all honesty. considering how even children could deal with it just fine. but shots really did terrify you.

it wasn’t about the needle itself or the fact that it was sharp, but rather the act of injecting something into yourself. the things injections could do once they entered your body. if the intent was malevolent it could be internally destructive, and the likelihood you wouldn’t be able to do anything about it would be high. you had always been a wary individual. any situation with danger out of control is something you would never allow.

all of which was a major reason behind why your current circumstances were just so frightening. seated next to the boss of the port mafia, a feared man known for nothing if not his cruelty. so why did he stand so non threateningly now?

it was like his entire persona had been replaced. whether he had finally taken off the cold mask used to manage the mafia or if it was the face you saw now that was fake, you had no idea. for all you knew neither could be the real him. it was impossible for someone like you to know. it was impossible just for another one of the many assassins in the mafia to be able to read mori himself, the notional alone was ludicrous.

“once again, i’ll ask you to please relax. tensing your arm will only make the injection more painful.” mori’s exasperated sigh pulled you from your line of thoughts. “i promise, there’s nothing to fear. i have no ill intentions. you know that, don’t you?”

“i know.” you spoke, but didn’t sound at all confident in your own words.

rationally, he was right in every aspect. mori wouldn’t bother with killing you himself if he really did want you dead. and in the scenario he did, he would never choose a method as bizarre as this. there would be no need for him to try and comfort and guide you through the process. as a matter of fact, there would be no reason for him to lie about his intent to kill you at all. he just would. but even still, you were so terrified you couldn’t bring your heart to level with your logic. no matter how irrational it was, fear clinged to your soul.

“just relax, okay? you’re safe with me.” mori cooed, attempting to coax you into some sense of security.

“okay.” you huffed. resigning yourself to your fate. no matter how little sense it made for mori to insist on being the one to administer your flu shots, you still had no right to decline the boss’ wishes. with some apprehension you relaxed your arm and squeezed your eyes shut, you didn’t think you’d be able to keep the arm relaxed if you watched the needle dig into you. mori allowed a satisfied smile to take over his face when your attention was off of him.

“all done.” his cheery voice spoke up far sooner than you had expected it to.

“already?” your eyes snapped back open, surprise evident on your features.

“yup! that wasn’t so bad, now was it?”

“i guess not…” you shrugged your sweater back over your shoulders once he had placed a bandaid where your skin had been pierced.

“i told you so... you're free to go back to whatever you were doing now. i’ll be here if you need me.” mori spoke as he cleaned up the tools he had used for the injection. he moved methodically, tucking everything where it belonged and clearing the space around his office without a hint of hesitation in his actions.

without another word you left. mori hummed to himself as he finished tucking the needle away. small steps.

everything is going as he planned. even if that plan meant everything was going rather slow, that was fine by him. mori is perfectly capable of being patient when he needs to be. if slowly building your trust through small actions like this is what it would take, he wouldn’t rush the process, as tedious as said process may be… it would all be worth it in the end if that meant he could have you by his side. and at this rate it wouldn’t be long.
