I read your yandere Overhaul headcannons so can I get a scenario based on it where the reader is sick and tired of Kai’s cruelty that she would rather die until she meets Setsuno so they escape without Kai noticing and got married. Then several years later Kai found them so he and setsuno fight to the death. It’s your choice on who wins. Bonus points if reader and setsuno calls Kai out on his abusive behaviour
This took a little bit- I hope you like it though
Thank You for requesting!
TW: non-canon character death, mention of past abuse, mention of blood & gore, character death, abusive relationships, and manipulative behavior.
Yandere! Kai Chisaki x Reader x Toya Setsuno
It had been two or three years since you had seen him, Overhaul that is.
Perched on your seat with a cup of coffee between your fingers, you watched the television. Shoulders shaking a little from the cool bite of your apartment. It’s true that Chisaki treated you terrible, but at least he could afford a home for the two of you. It’s okay though, you and Toya were getting closer to buying the home the two of you really wanted.
Your scrubs were dark in color, and the sun was just now starting to peak over the horizon, highlighting them as you rose from your seat. Your quirk allowed you to have this job, taking their illnesses and putting them on yourself, you couldn’t die from them (or at least you didn’t think you could), but it made you an excellent nurse; You could remember Chisaki saying something about your quirk. It was back when the two of you were actually together, loving, and most importantly, not abusive. “Your quirk is going to help me... and the others so much.” You realize now he only meant himself. You were only supposed to heal him, fix him, and you were the only person he would let close enough to do that; You could imagine how enraged he was when he found out his personal nurse was missing with one of his subordinates.
Toya knew he would be enraged. Hell, it hurt Toya himself that he betrayed Overhaul in such a way, but he couldn’t watch you suffer the way you were. He had never seen you so happy when he took you away from the grip of the much angrier man. He only meant to bring you away for a time so you could be free, but he himself fell head-over-heels. Hell, he was even doing hero work now, and he switched just for you. To help the both of you, to support the both of you. He didn’t have any regrets anymore, he used to of course, but that was two years ago. He adored you and tried his best to make ends meet, and you were both so close to getting out of the ruddy apartment the two of you had to stay in.
Toya was wary of what he’s doing, he always is. He was positive that he saw him. Overhaul. There’s no reason for him to be so far out this way, no reason except for you. Of course he was searching for you, he hated it when his possessions were taken from him, especially the ones he truly valued. Toya could feel his heart ache at the idea of him getting his globed hands on you again, he couldn’t bare the thoughts it brought along with it. You suffered when you were with Overhaul, and he couldn’t risk you going back to that pitiful state. He almost jumped out of his skin when a fist met his face, and then he knew he was going to get hurt.
His body crashed into the asphalt from the force, even if he was quick to recover. He hadn’t seen Overhaul in a long time, but he was still just as intimidating as he was two years ago. His eyes are squinted down at Toya, his hands balling into fists before they release again. Calming himself enough to speak, or mumble.
“If you tell me where they are I might just let you live, Setsuno.” His voice is slightly muffled from under his mask, and Toya wished he had something a lot less intimidating on. He knew it was true though, this was a bad match-up and he knew it. “You can’t- just take them back after how you treated them- abused them- could you not see how desperate they were to get away from you?” He backed up when Chisaki stepped forward, knowing for a fact that close range would get him killed. All Chisaki needed was one solid touch and he’d die then and there.
Overhaul is a whole lot smarter then his subordinates, and the passion of finding you raging in his lungs distracted him from the bloody lesions on his arms and face, his gloves ripped to shreds and his shirt rather soaked with a mix of both his and Setsuno’s blood. The poor blonde laid in the alleyway, his hair caked in what looked black in the darker light. Chisaki would have prefered to get ahold of him in the dark, but this would be fine. He sank to his knees beside him, shoving his hands into the pockets of the man in search of his phone, his eyes almost softening when he found it, even if it was covered in blood he was too desperate to get ahold of you to think about it. Tracking apps really were useful in this turn of the century, he only had to note the name of the clinic.
You’re cleaning when he comes in, scrubbing down a room before being told another patient is there for you. It’s not uncommon for them to ask for you after all, you’re considered popular when it comes to this kind of thing. So taking a clipboard you take note that this isn’t a usual visit, noone whose came before. Not even the name rings a bell as you sanitize your hands and start walking back to the room he was in, your heart jumps into your throat when you see him. He’s messing with the sink, scrubbing his skin as best he can. He looks over his shoulder for a moment and almost jumps when he sees you, his brows raising, “I didn’t think you actually worked here- how are you?”
You’re not sure how to respond, staring at him from the door way before gulping a bit, “I’m- fine. Chisaki.” He raised after that rubbing his arms dry with a paper towel, “it’s good to see you- I actually had something I wanted to say- oh but first i’ve got an issue. I... got pretty beat up.” He wasn’t wrong, as you looked him up and down you noted his lack of a mask and the blooming bruises all over his face, his skin marred and torn, “Sit down.” He raised his brows at your demand, but soon enough he was perched on the table, watching you as you approached, reaching out- just for him to snag your wrist, “wash your hands.”
That’s right, you almost forgot with the fear that built up in you, pulling your hand away from him to go and do as you were told. You could feel his eyes boring into you at this point, his shoulders rolling as he huffed.
“Is it not obvious? I got into a fight with a pro-hero and got my ass handed to me.” His brows furrowed again, and you almost expected him to leap off of his seat and begin choking you in a fit of rage. “Oh.”
The rest of the exam was in silence as you patched him up, his skin quivering at the cold of your hands before he turned around, he seemed so much friendlier in the moment, “I’d like you to come back to the agency- I already asked Setsuno to head there... I know your living conditions haven’t been the best- and I know I haven’t been the friendliest to you, but I don’t want the two of you falling into the sickness-“
“I get it Chisaki. You don’t have to go on a tangent... but... I mean it doesn’t sound bad.” Your eyes drift off to the side some, “If Setsuno went then I guess I ought to come with.”
“That’s right- I don’t think you’d make it out here without someone to support you, even with this job, pro heroes are the one making the money. Come on we can go together, alright?”
“No- you have to promise me first. You’re not going to lie a finger on me the way you used to. You’re not-“
“Of course not, I know I hurt you, and I want to make things right between the three of us. Is that do bad of me?”
“No it isn’t... just- give me a minute to get my things together...”
It was easier then he thought it would be, a smirk pulling on his lip before sighing, watching you leave with a not so friendly look in his eyes.
He was prepared for you to sink into the passenger seat of his car, it wasn’t unusual either. You almost melted at the familiar feeling, if it wasn’t for the man getting in beside you and reaching over to the glovebox you would have stayed at ease too, almost expecting him to strike you before you calmed down, watching him open the glovebox to search for one of his many black masks. It was an obsession of his, as he was a germaphobe in every sense of the word.
“How’d you even find Toya?”
“He was patrolling and we happened to bump into one another... after he walked away I ended up getting beat up by some sick ‘hero’.” He shook his head as he started the car, beginning to drive in silence.
“Chisaki I’m still- upset about what you did to me.”
He was almost shocked at your bravery to talk to him about this alone. It sent shivers up his back, he’d have to fix your new-found confidence, and soon too.
“I know... It’s not fair how I treated you, but i’m trying to make it right. I just hope you’ll forgive me.” His eyes drifted to you for a moment before snapping back to the road, “Toya seemed horrified when we bumped into one another- I think he thought I was going to rip him to shreds... I’d never- not in daylight at least.”
“Chisaki- I really don’t want to talk about what you do to people.”
That confidence of yours is most definitely getting on his nerves. He hates it with a passion, and it’s Toya’s fault you’re brave enough to talk to him like this. How dare he mess up his perfect darling. The rest of the ride was filled with silence, though every so often Chisaki would continue some of his delusional rambling about the sickness of the world and how he planned to fix it for the greater good. It was warm in his car, the heated seats keeping you from leaping off the leather, and you held your seatbelt close to your chest, “Is Eri-“
“Hush. You’ll see her and Toya when we get there.” He almost snapped at you, catching himself before he truly got a chance to go off on you. He can’t scare you yet, it’d be cruel to make you ride with him like that. Even if he did want you to learn your lesson. “Okay...” your voice was quiet, he hoped you were thinking about everything he’s done. He hoped you were shaking from fear and not the cold of the outdoors, he wanted you to be horrified of what he had in store for you. Soon enough though, the familiar gate to the agency came into view, and he watched as you sank into the seat a little bit, averting your eyes out the window rather then looking at him or the building. Slipping out of the car was even worse, Overhaul coming and taking what little things you had brought with you out of your hands. “You know I actually quite like how scrubs look on you, maybe you should think about wearing them more often.”
“They’re- nice looking, but they’re freezing too...”
“You can just wear my jacket.... not that you have any complaints about wearing it.” He’s chuckled, a cold harsh sound that sent shivers up and down your back. Something was wrong.
