Chapter Text

Your heart was pounding as you ran as fast as your feet would carry you, silently cursing yourself for attempting to take that damn short cut. Where the hell were the heroes when you needed one?

“Get back here, bitch!!” you heard the man chasing you yell. What the hell kind of quirk is knives for hands anyway?! You didn’t have much time to question as you turned a corner and continued on your way. Just a few more blocks and you’d be home free!

‘Get out of my way,’ rang through your head, and before you could process it you were dodging out of the way of a different man, catching only the slightest glimpse of his… plague doctor’s mask? Before you fell hard, using your arms to brace yourself for the impact. Fuck, that was going to leave a mark.

You quickly turned around in horror, there was no way you could get up before that bastard who tried to rob you got to you.

‘Diseased filth,’ the same voice growled as the man you had dodged to avoid reached out, barely touching the man as he was about to lunge at you. Instantly he exploded, blood and guts splattering everywhere. Your eyes widened as the realization hit you. ‘Now I’m filthy.’

You quickly got up, dusting off your knees before turning to him. “E-excuse me…” The man turned to you, finally allowing you to get a good look at him. He stood roughly 5 foot 8 inches. He wore a green hoodie, with purple fur in the hood. A black shirt with a white tie sat under the hoodie, along with black pants and pure white shoes. The strangest two things about this man were the pure white gloves, one of which he was putting back on, and the beak-like plague doctor’s mask on his face. He stared at you with a bored expression, his golden eyes piercing through you. “Thank you, for saving me--”

“He was in my way.” you were cut off.

“Well… you still saved me, in doing so… So thank you” you looked down at yourself, you were soaked in blood, just like this man was, you felt like you were going to be sick. “A-as a thank you, please follow me back to my place. It’s only a few blocks away. You can get cleaned up there, and I can throw your clothes in to wash.” he stared at you as you shuffled in place. You were visibly uncomfortable with the dirt and blood that lay on your clothes and skin.

“Lead the way.” His voice was raspy, but not too bad to listen to. You nodded and began walking, keeping a close ear on his thoughts.

Mind reading was a very useful quirk to have, but when it came with a 20-foot radius, only able to focus on one at a time, it wasn’t as useful as you would think. Especially when you’ve kept it a secret your whole life, including from your parents and the government. It was none of their concern what you were able to do naturally. But one of the advantages was when dealing with new people, you could hear if they were planning something bad.

It didn’t take long to get to your home, you weren’t kidding when you said your it was only a few blocks away. Once inside you took off your shoes, replacing them with white booties. “Place your shoes there,” you said as you pulled out another pair of booties out of the cubby hole you kept by the door, setting them down for him. He looked at you, curiosity swirling in his golden eyes. “And please, don’t mind the smell… and disorganization… I was in the middle of my monthly deep clean when I ran out of a few products.” He listened to you as you led him down the hallway, looking around at the almost sparkling clean environment.

“Here’s the bathroom. There should be a robe that’s big enough for you in there. Set your clothes out here and I’ll throw them in to wash.”

Silently he opened the door as you bowed before leaving him alone.

You needed to get these clothes off and your arms washed. With the stranger in your bathroom, you had to use the sink in the kitchen, before going to your room and changing. On your way back to the kitchen you picked up the dirty clothes, holding them as far from your body as you possibly could, before separating them and throwing them into the wash, using an ample amount of detergent and softener. Afterward, you threw on a pair of gloves and soaked his white shirt in an OxiClean detergent mixture, swirling it around and washing it by hand.

You were so focused on cleaning his tie you didn’t hear the footsteps coming up from behind you.

“What are you doing?” your body went rigid before you turned around.

“Dark colours bleed… So I’m washing your tie by hand, so it can dry with the rest of your clothes.” You drained the basin and began rinsing it out, looking it over to make sure you got all the blood out. Satisfied you hung the tie up over your dryer, so you wouldn’t forget to throw it in with the rest. You turned to him, obviously embarrassed. “I’m sorry about all of the… precautions. It’s just… germs are everywhere-”

‘She’s a germaphobe,’ he concluded, obviously unaware of your quirk. “It’s fine,” was all he said out loud.

“Would you like some tea while you wait?” He eyed you.


Almost an hour later you were bidding the stranger good-bye, his clothes fresh and clean. While the tea was brewing you had quickly scrubbed both pairs of shoes, making them practically sparkle, so now there was no evidence on either of you to show you were part of that… incident.

As you resumed your cleaning from earlier that day you couldn’t help but think to yourself. That mask of his looked vaguely familiar. You settled for figuring it out later, you were way too far behind on disinfecting your home.

After hours of cleaning and a nice, long, hot soak in your tub, you flopped down on your bed, grabbing your freshly cleaned laptop. Getting comfortable you brought up your social media sites. It felt good to have everything spotless again.

You happily checked your notifications and messages, before scrolling through Facebook. Meme, meme, meme, inspirational quote, meme, someone complaining, news article.

Oh, news article. “Shie Hassaikai strikes again?” wasn’t that one of the last remaining mafia gangs in Japan? You clicked, your curiosity piqued.

The Shie Hassaikai is believed to be behind the murder of small-time criminal, Asahi Ito, earlier today.
Hey, that was the guy who tried to mug you earlier.
Ito was known to occasionally mug people, usually late at night, but authorities believe he might have been attempting to mug Shei Hassaikai’s captain, Kai Chisaki.

Your blood ran cold. That was where you recognized that mask from. Staring back at you from behind your screen was the same man you had in your house just hours before. He showered in your bathroom, you washed his clothes, you shared tea with him while he wore one of your extra robes. You had helped an extremely dangerous mafia boss out.

The article continued to explain Ito’s background, along with a small history of the Shei Hassaikai, and an even smaller snippet explaining Chisaki’s quirk. Overhaul. The ability to disassemble and reassemble anyone or anything, with the choice of leaving it disassembled. That must have been what he used on Ito.

You originally weren’t too bothered about what happened; a lowly criminal, one the police never really rained in and the heroes deemed too low of a priority, got what he deserved from a bystander. Now knowing that the bystander was actually a crime lord, it wracked you with guilt.

Thoughts of what you should have done and can’t do anymore slammed into your head. You should have ran home and called the police right away. Now, if you were to call them they’d accuse you of trying to cover up for him and you’d be charged with accessory. What if he comes back, wanting to finish the job, afraid you’d turn him in?

These thoughts wracked our brain into the early morning, causing you to toss and turn. You’d fall asleep and then wake up in a cold sweat, panicking.

The next few days you were exhausted as you made your way from house to house, face mask, gloves, booties and safety equipment on as you scrubbed walls, carpets, floors, cabinets, everything. You loved your job as a house cleaner, but some people can be super gross… most people… All people.

At the last house on the fourth day you realized you needed a stronger cleaner than you had brought in and made your way out to your company vehicle, digging through the back for it. With a smile you pulled out the blue bottle and closed the door, locking it.

‘There she is,’ the voice that had been haunting your nightmares rang in your head. You had to force yourself not to drop the bottle.

Pretending you didn’t know he was back he was near you turned around, giving a fake jump in shock.

“Oh! It’s you,” your voice trailed off.

“What’re you doing here?” Cutting to the chase, huh? You stared at him for a moment.

“Work, this is a client’s house,” your lips thinned at the assumption that ran across his mind. “I’m a house cleaner, I clean houses.” Kai looked at you before casting a glance at your company’s vehicle.

“By the way, I don’t think I got your name?” Not that you didn’t already know it, but it felt weird.

“Overhaul,” that wasn’t the name you read, but if that’s what he prefers to be called. He stared at you expectantly.

“Oh! (L/n) (F/n), it’s nice to meet you,” you bowed, a little lower than you meant to, before looking back at the house. “I should… Probably,” and before he could say anything further you quickly made your way back into the large house, feeling his gaze prick the back of your neck.



If you weren’t afraid of him before, you definitely were now. Three weeks had passed and it felt like everywhere you turned you would see him, or another crow-like masked man. You were so jumpy that the smallest noise at night woke you instantly. You were beyond exhausted, living off of energy drinks and super strong coffee.

“(L/n),” you answered your ringing phone.

“Hey, I know you’re at capacity right now, but we just had another customer drop in.” you groaned lightly as your boss hesitantly spoke to you. “I know, I know. But they’ve been requesting you for a week, and at this point I just want them out of our hair.” You were pretty well known in the house cleaning business, so having people specifically request you wasn’t something new to you. You could say you had a small waitlist piling up.

“Boss, please. You know I love doing what I do, but,” you pulled out your planner, “My next opening is in two weeks,” that was the best you could do.

“They insist it be today. Said they have an important guest coming.”

“Boss, you know that’s not possible,” you growled, the exhaustion making you lose your patience. You were booked past your usual capacity today, as that was only to keep your mind off of your new-found stalker. “I’d be out until midnight, maybe longer depending on size, if I take another house today.”

“They said they’ll pay you double?” You took a deep, steady, breath, running your free hand over your head, smoothing out any loose hair. You probably looked insane right now.

“Send me the damn address and tell them I’ll be there around 10:30. NO earlier.” You started your vehicle and began driving towards your home. You needed more coffee and another energy drink. Time for a little detour.

Hours later you were dragging your heavy limbs and work bag to the front of the… house? Compound, it was a fucking compound. With the size of this place, you were going to be stuck here until at last 1:30! You gathered a breath, reminding yourself how much they were willing to pay. ‘Rich people pay big money. Rich people pay big money’ you repeated to yourself as you entered the opened gate, walking up to the front door and knocking.

You heard the man before you saw him, ‘fucking finally.’ Great, they’re going to be grouchy. You thought to yourself as the man opened the door in front of you. You took in his features as fast as you could. His most prominent feature was his hair. Pure white and in the shape of… were those arrows? Those were totally arrows.

Not the weirdest thing you’ve seen in the past few months.

“Boss has been waiting for you,” He stared down at you, bored.

“I’m sorry, a few of my previous assignments took longer than anticipated.” you just wanted this done and over with, “But I’m here now! Where do you want me to start.”

“Boss wants to see you first. Follow me.” without so much as a glance back he turned around and started walking into the house.

“W-wait! My shoes!” you stepped in, leaning against a wall to take off your shoes and replace them with a pair of work booties. The man paused for just a moment, then continued as he heard you run after him.

‘What’s so special about this one?’ Your eyebrows furrowed a little, listening ‘she’s plain, and a mess,’ well that wasn’t exactly your fault. It was pushing 11 at night, you were worn out from a hard day’s work and no sleep. ‘He made me stand at the door, for two hours, for this? His standards are laxing.’ Does he have to be such an ass?

He led you, “silently”, to a study. The whole time mentally throwing insults your way, unknowingly.

The room he led you to was very much a study/office mixture. A large wooden desk sat at the bad wall, two leather chairs sitting in front of it. The empty space between the chairs and the door was filled with two black leather loveseats, facing each other, separated by a low coffee table. Flanking the room were four large bookcases, each one taking up half a wall each, they must have been built in the room.

“Wait in here, the boss will be in momentarily.” he looked down at you over the tip of your nose. As you stepped into the room. Before you could say anything he was gone, closing the door behind him.

You walked over to the coffee table and set your bag down on it, pulling out a pair of gloves and your duster. You knew you couldn’t sit down, if you did you probably wouldn’t be able to get back up. So, instead, you settled for starting early, by dusting one of the bookshelves. You began at the highest shelf you could reach, your movements sluggish but determined.

It wasn’t long before a voice rang in your head.

‘Finally, she kept me waiting long enough.’ the book in your hand dropped, horror shaking you to your core.

Shit, shit, shit. You quickly bent over, grabbing the book. Dusting it off you clung to it, trying to ground yourself. You had only seconds to calm yourself before the door opened.

“(F/n),” Overhaul’s voice pierced the silence in the room.

Stay calm, just stay calm. You thought to yourself as you slowly turned around, eyes wide like a deer in headlights. “Overhaul,” your overworked and exhausted brain fought to find words. “Are you my--” you trailed off.

“Client. Yes, I am.” He spoke as he stepped into the room, two figures following. Slowly, methodically, as if to intimidate you, he made his way to the desk. He didn’t sit behind it, he leaned against the front, arms crossed in front of him. He wore what you had originally met him in, except he wasn’t wearing the hoodie or his shoes.

The first figure, you recognized as the one who led you into this lion’s den. The second was one you had seen around a few times. He wore a wide brim black bowler hat, a pure black cloak obscuring any physical features he had, with white shoes. A pure black plague doctor’s mask adorned his face, making him impossible to identify. They flanked him.

You were at a complete loss for words. He had been following you, shown up at your work, he had some of his goonies follow you, he harassed your work, he… you had tried to avoid him, and now you were stuck in a room and two of his men.

“(L/n), (F/n),” he drawled, holding out his hand, motioning for the cloaked figure to materialize a folder from under the black mass he wore, “(Height), (Age), (weight), (Mother’s name) (Father’s name).” he read from the folder, “you grew up in a family with emotional and mental quirks, but you never got one. You have three siblings- a brother and two sisters. Lived alone in a two-bedroom one bath home.” he looked up, meeting your eye, as if challenging you to correct him, “welcome home.” Your eyes widened in horror. This was a trap. You should have known this was a trap. Your eyes darted between the men, reading their minds one at a time, as quick as your mind would allow.

‘She better not try to run, I don’t feel like chasing her.’
‘Useless, he’s just going to get bored of her.’
‘Checkmate.’


“What are you thinking?” a wave washed over you, forcing your answer.

“I have to get out of here,” your voice came out as a whimper before you threw the book you didn’t realize you were clinging to at them, and bolted for the door.

No one made an effort to stop you as you ran down the hall, sliding around a few turns. Once you got to the door you went to grab your shoes, only to realize they were gone.

'Ok, this is fine. Everything’s fine. It’s fine. Just… go. You can do this.' You thought to yourself, steeling your nerves to run outside, in nothing but your socks and booties. The footfall echoing behind you forced your hand as you threw open the front door and ran into the night.

You ran into the driveway, going straight to your vehicle. Trying the door you realized it was locked and you couldn’t find the key.

Fuck! They’re in my bag! Which was in the office.

Leaving your vehicle behind you ran towards the road, wincing at the rocks pressing into your soft feet. You just needed to get to the road, there you could run and find a hero, tell them everything. You just needed to--

A pain grazed your left shoulder before you could even get around the vehicle. You felt your whole body pulse before you took a dive into the pavement, unable to stop yourself with your arms. You felt as the asphalt scratched at your chin and arms, causing an uncomfortable sting.

“I didn’t want to chase you,” arrow-hair said, as he stepped from his attacking position, the doorway. Your body moved as if the air was made of molasses. You watched his feet as they slowly walked over to you, picking you up easily. “I don’t understand why the boss is so enamored with you, but if you’re what he wants, you’re what he gets.” Slowly you moved your hand to his chest, trying to push him away, trying to get away, to do anything. “Don’t bother. I hit you with the minute hand, that’s all the time I need.” no… no no no. You panicked. You couldn’t move, you couldn’t fight. The only thing you could do was read his mind, but that didn’t help you in this instance.

The man carried you down a flight of steps, further than you thought the building went. Something like an underground bunker, it was bleach white, resembling a hospital.

He was not gentle as he dropped you onto a soft white bed, staring at you coldly, “Boss will be in shortly.”

You stared back at him, eyes wide as you quietly begged, “p-please, please don’t do this. I just-- I just want to go home.” oh, this place was probably filthy. When were these sheets last washed? You could already feel the dirt soaking into your skin.

He ignored you as he walked out, shutting the door. Tears welled in your eyes and began rolling down your cheeks, you could barely move to wipe them.

Your eyes snapped to the door as it opened, revealing an amused Overhaul. You watched him as he stepped in and closed the door. You began hyperventilating as he walked over to you, removing one of his gloves.

“I really don’t like when my things try to leave me,” his voice was low, “but it’s your first offense, so I won’t punish you. Much.” Your eyes squeezed close as he reached down, touching your forehead, sliding his hand back. Was he petting you? ‘Just a few things, then she’ll be perfect.’

You were ready for pain. What you weren’t ready for was to feel the stinging on your chin to subside, nor were you prepared for the effects that plagued your body to just disappear.

Slowly,you moved your hand, testing your mobility. The moment you realized you could move properly once more you sat up, scooting away from him, to the other side of the bed. Your eyes darted around the room, barely taking it in.

Overhaul watched you as he slid his glove back on. You looked like a cornered mouse, it caused him to smirk under his mask. He took a step around the bed, causing you to jump up to back away.

At least… that’s what you tried to do. The moment you put pressure on your legs you realized they couldn’t hold your weight and you fell into a heap on the floor. You watched in horror as he walked over to you, picking you up and holding you to his chest. “I thought you’d be more honorable,” he walked out of the room, heading back to the main floor.

“H-honorable?” you questioned, unable to wrap your head around what was going on.

“I saved your life, therefore it’s mine.” he glanced at you as he walked. “This is me collecting on that debt.” your blood ran cold. ‘Took longer than I wanted it to, but she’s finally mine.' Images of you flashed through his mind, some cute, smiling up at him in happiness, others lewder. The one that stood out the most was you on a fluffy white comforter, a small white circlet around your neck, connected to a white chain that trailed out of view. You laid with one arm bent slightly under you, slightly propping you up, the other nestled between your breasts, resting above your heart. You wore silk white panties, and a top that had white silk obscuring your breasts, white mesh covered your stomach. Something was off.

Your hair and eyes were both pure white, like freshly fallen snow.

He took you into a large room, gently laying you on the bed. You stared up at him before looking around the room. Directly across from the foot of the bed stood a full-length mirror. You stared in horror as you reached up a shaking hand to touch your now white hair, then touch around your eyes. You were so focused on your hair you didn’t notice Overhaul walk to the dresser and pull a few things out, then set them on the bedside table.  

“Beautiful, isn’t it? White’s the colour of purity and cleanliness. Both fit you,” Your eyes snapped to him as he reached forward with both hands and began to pull off your shirt.

“Wait! What? No, no stop!” You quickly tried to move out of his grasp before he gave you a look, causing you to stop in your tracks. You squeezed your eyes shut as he took his time undressing you, occasionally running a gloved hand over your skin.

“Perfect,” you heard him breathe out before both hands disappeared. It took time, but he managed to get you dressed. “Open your eyes and look,” he commanded you.

You did as he told, automatically looking at the mirror. It was a simple spaghetti strap white dress. He just undressed and dressed you, and you were too scared to stop him. You dared to glance at him in the mirror watching, as dread soaked you to your bones, as he sat beside you on the bed, clasping a small white collar around your neck, exactly as you had seen him think about. “I made sure this room was cleaned to your standards,” he said before pulling you into his lap.

He held you like a child, gently rocking you as you silently watched him in the mirror in horror.

You tried to stay awake, you didn’t want to sleep around him, around any of them. But you were so tired, four weeks of little to no sleep, on top of a long workday was enough to make anyone pass out immediately. Add the chaos you just endured? Your eyes closed within moments of feeling his hand pet your head.

“From now on, you’re mine.”
