Tidy

First and foremost, being Kai’s darling requires a certain level of cleanliness.

They by no means need to be a germaphobe or obsessively making sure every surface is spotless, but keeping their living space fairly clean and orderly is something incredibly appealing to Kai.

And once his darling is living in the base and has a room all to themselves, it pleases him greatly to see his darling’s bed neatly made every morning, their clothes (all hand selected by him, of course) hanging up in the closet, or any other small display of them just generally wanting the area to be somewhat neat. He likes the reassurance that his darling has a bit of sense about them, that they understand that cleanliness is important.

And honestly, one of the most heartwarming things Kai can imagine is his darling purposefully cleaning something for him, that they’re willing to spend their time and energy voluntarily making sure that something has been sanitized, cleaned or straightened up all in the name of making him more comfortable, of helping alleviate some of the disgust and fear of his everyday life.

He loves the idea of his darling being a sweet little domestic partner, a housewife of sorts, and if they have a natural liking of keeping things on the cleaner side?

Well, it only makes Kai fall harder, deeper, more completely, because god, how is his darling so fucking perfect for him?

Sweet

Kai is honestly a bit pessimistic; he’s not especially positive about things in life, not especially kind or forgiving, and though he hasn’t really given much thought to what he does and doesn’t find attractive, even he can’t deny that there’s a certain allure to someone who’s the opposite of him; of his brash and cold words, someone warm and sweet and soft.

A darling that doesn’t hesitate to throw kind words at him, to praise the people around them and just generally make people feel good about themselves is something he quickly becomes enamored with, the compliments at first catching him off guard.

His darling saying something along the lines of wow, the gold in your mask really brings out the shades of your eyes – it’s really pretty, is only met with Kai’s cryptic, stoic stare, making them shrink in on themselves while he internally tries to process the idea that his darling likes his eyes.

He’s confused at first, slightly irritated and wondering if they meant it in some sort of derogatory or mean way, but as his cold eyes search their own warmer, slightly nervous ones, he’s taken aback to realize that they mean it, that they’re being genuine with their words.

Having growing up in the yakuza and being surrounded by criminals and a parental figure that used tough love more than anything, having someone actively praise him or deliver compliments is something he’s completely unused to, completely confused by. It leaves him feeling defensive, cautious, wary about someone's true intentions and how they're planning to use him.

But with his darling - sweet, incapable of any serious harm darling - Kai can’t deny the way a little seed of warmth grows in his chest, the words feeling strange but nice.

And as his darling only continues with their offhand compliments, their small, sweet words, Kai only grows more and more addicted to them.

And he tries his best to compliment them back, too - except it always comes out strange, the words feeling oddly forced and the sentiment not quite as sweet as he'd been hoping for.

(Frankly it comes off more threatening than anything – your hands are very clean, I want to keep them for myself paired with audibly heavy breathing behind his mask and golden eyes that won't stop looking at them.)

It’s a bit difficult for him to recover from their honesty, from the way his heart hammers against his ribcage at just one mere kind smile from them. It’s disorienting, but Kai would be lying if he said he didn’t absolutely love it.

Patient

He is, admittedly, a bit poor with processing and expressing his feelings; he’s never experienced a relationship or romantic feelings of any sort before he met his darling, and as a result he’s a bit clueless when it comes to courting them, to how he should act around them.

Of course, he wants nothing more than to completely woo his darling, to sweep them off their feet and get them to fall madly in love with him, but he’s realistic enough to know that no matter how many cheesy, dreadful rom-coms he watches, no matter how many articles or pieces of advice from colleagues and clients, it won’t change the fact that he’s just naturally not romantic, that he’s just not good with expressing himself.

He wants to be a wonderful partner, always spoiling his darling and making them feel treasured and loved like how he really feels, but it’s difficult for him to break away the layers of carefully built shields around himself, the thick skin he’s acquired through years of working in the underground mafia.

And, because of this, his darling absolutely needs to be patient – they need to be able to give him the time and space he needs in order for him to process his feelings, to try and make sense of how and when he should approach them about his desires to hold them, to see them smile.

And while it’s likely that his darling won’t even be aware of his obsession and romantic feelings towards them until much later in his infatuation, they need to be understanding of how fucking hard it is for Kai to be vulnerable, to allow any sort of happiness or weakness into his life.

Because really, his darling is his one true, huge weak spot – one he loves dearly and would give his life for, but still isn’t quite sure how to rely this to them.·

Smart

In Kai’s world, strategy, power and manipulation are everything; he needs to be at the top of his game at all times, making sure that he’s making the right decisions, playing the right cards and just generally making every possible move towards the restoration of the Shie Hissakai.

He’s constantly strategizing, thinking through decision after decision, scenario after scenario, and as a result he’s grown to demand intelligence out of those around him, to require brains and a general threshold of understanding for those he deems close to him.

And of course his darling is no exception. They don’t need to be book smart per se, but he needs to have confidence that if he were to explain something to them (though he avidly tries to separate his darling from any and all yakuza business, both on principle of minimizing their ability to sway his decision-making and also to minimize their perception of him as a monster) that they would understand. He wants the reassurance that he wouldn’t need to spend hours going over the same piece of information again and again before they finally understand.

There’s a certain attractiveness to intelligence that he can’t quite explain, but very much feels – when his darling makes some sort of quick remark or statement in response to something he said, there’s a sense of pride swelling in his chest, because that’s his beloved who’s so smart, so understanding and quick thinking. (And sometimes, depending on the nature of the remark, it can even get him freezing for a second, trying to process the quip or the tease, clearing his throat and shifting his tie because oh, how does he respond to being called handsome so nonchalantly?)

He really likes the idea of his partner and him being a bit of a ‘power couple’ (though he absolutely refuses to give up any of his own power over his work or them – he is in charge, as he always will be), in that they’re both forces to be reckoned with, smart and strong and a powerful team together.

It’s enticing, and though his darling likely couldn’t change his mind about anything, Kai enjoys asking them about their opinions and thoughts on certain matters, just to understand how deeply they agree or disagree, how deeply his darling’s smarts run.

That, and Kai will be taking every possible opportunity to bond with beloved, even if talking about hero society is the way to do it.

GENERAL YANDERE TRAITS:

Controlling

Kai is, as in most aspects of his life, absolutely desperate to be in charge of every little thing around him. He needs to be dictating every single thing you do, everything you say and think and feel. There's a compulsion that eats away at him every moment that you're not in his sight, something tugging and yanking at his chest to see you, to look at you, to tell you exactly how to eat and sleep and bathe and breath. And he's not being dramatic when he says that he has to - otherwise things get ugly, quickly.

There’s a part of him that’s absolutely terrified that you hold so much emotional weight over him, that he cares so much about you, that he does things because of you.

He doesn’t like the way he feels so helpless in the face of you, even as unassuming and weak as you are.

(It's pathetic, really, the way his heart clenches in his chest when you look at him with those pretty eyes and pout at him with those fucking lips, your little, almost sultry please, Kai slipping from your tongue and making his knees weak. It's pathetic, sure, but what's even worse is the way he has to physically fight his body from immediately - and eagerly - telling you yes, agreeing to anything and everything you request of him just to keep you looking at him like that, seeing him and acknowledging him and needing him.)

Kai craves for you to feel the same overwhelming, disorienting love that he does for you, but more than anything he craves absolute control over you. He wants power over you, to know that you will follow his every word, his every command, anything and everything he could ever want.

To him, it shows that you trust him. It shows him that you love him and that you’re giving yourself to him, to let him love you and show you how much you mean to him.

In his eyes, it’s all actually strangely romantic – you’re his sweet little quirkless woman, the girl he thinks he loves, the one he’d do anything and everything to protect and keep his, and in return all he asks is that you let him decide everything for you, that you depend completely and solely on him.

It’s a fair deal, really, and after all, he knows what you need much better than you do - after all, he knows you better than you know yourself. (Something that will become very, very apparent early into your captivity with him - he's more observant than he seems, and it's not long before he's got your habits memorized. He knows what order you put on your clothing, how you bite your lip when you get impatient, how you tap your fingers when you're thinking. He even knows the way your face scrunches up when you sleep, how you mumble and groan and if he tries hard enough, he can almost pretend to hear his name slipping past your lips.)

He has, for lack of a better term, a brutal schedule that he keeps you chained to. He’s rigging an alarm for your room that goes off at exactly 6:30 in the morning, a steady beeping noise that does the job quite nicely, if the camera feed showing you frowning and covering your ears with the single pillow he’s given you is anything to go by.

He’s sending in a henchman (masked, so that there’s no chance of you finding him attractive or connecting with him in any meaningful way) with a tray of nutritionally balanced breakfast items that you will eat, lest he’ll use force against you. (Never real force, of course - he can't stomach the thought of hurting you, but a little bit of intimidation and persuasion go a long ways - he might not be willing to hurt you, but everyone else is fair game.)

Your breakfast will consist of a pile of meat of his choosing, steamed vegetables on the side, and a small container of starch next to the plate.

A smattering of vitamins are enclosed in a small box in the corner of the tray, the some ten different pills ranging from the size of his pinky nail to a quarter patiently waiting to be swallowed.

(When you ask, he doesn’t tell you what they’re for - he just tells you they’re good for you, that you’d better take them, we wouldn’t want you getting sick, now would we? You don’t need to know that they’re all for diseases or conditions that run in your family - he'd checked your medical background almost immediately after accepting his infatuation with you. You aren't showing symptoms of any of the conditions, so it’s just a preemptive measure to make sure you don’t develop them, that nothing could ever harm you and take you away from him. Plus, the small white one you eye suspiciously will help him in the future, he hopes - after all, he’s certainly not ready for you to fall pregnant anytime soon.)

You’re scheduled for testing most of the day after that – various blood tests, check ups on your physical and mental health, mandatory meetings with him in his office to discuss your ‘progress’.

(You’re still not exactly sure what he means by that - he won’t give you details when you press, instead getting this weird sparkle in his eye while he stares at you, the eye contact making you squirm while he tells you that you’re very important, you’re the key to my success.)

Dinner is the same as your breakfast, and directly after is a shower that lasts for ten minutes – no more, no less, where you’re required to shampoo, condition, and scrub your body.

(You don’t know it, but there’s a camera set up in the corner of the shower that’s constantly rolling, just so that Kai can get some peace of mind and make sure you’re doing as you say - it’s certainly not to aid him when it’s late and he’s sitting in his office, eyes trained to the screen as he aches and throbs and yearns for you, both aroused and disgusted by the thought of being intimate with you, of being inside of you…)

You’re to be in bed by 9:00 at night, tucked underneath the covers and eyes closed so that you get the proper amount of sleep, ready to be awoken so rudely the next morning and repeat it all.

(And you're to wear the pretty, silky nightgown he'd selected just for you - he'd agonized over the decision much more than he'd care to admit, letting his cheeks turn ever so slightly pink at the thought of you in all the pretty cuts and styles. He'd wound up with something simple - a slip with thin straps and a small lace trimming at the top and bottom, the material just barely sheer enough so that in certain lights he can see through and catch the slightest outline of your nipples.)

Deviation is quite rare in his itinerary for you – sometimes he’ll join you during your meals, or inform you that certain tests are being postponed until further notice, but for the most part Kai will absolutely be keeping you on his regiment – having such obvious control of you is something that he needs, a requirement he’s simply unwilling to compromise on.

The feelings you give him are already disorienting enough, strong enough to leave him feeling weak, dependent, angry, and the only way to regain some semblance of power is to show you that you utterly and completely belong to him, that you have absolutely no control over your new life.

The new life in which you're Kai’s beloved perfect partner, even if the notion makes you scoff.

Possessive

Because Kai has never really developed feelings for anyone in his life, romantic or really even platonic outside of Pops and Chrono, you present an anomaly for him.

The way that he feels for you, the desperation that overtakes him where you’re concerned is something he’s completely unfamiliar with. It's something strange and new and something he isn’t entirely sure how to handle.

(He’s never been a fan of romance, and has spent very little time indulging in any sort of media discussing the topic, and as a result he does genuinely feel like a fish out of water, even if he doesn’t entirely hate the experience.)

And really, the strangest thing about the development of his feelings for you is the way that he just reacts to you, unconsciously moving or thinking things he would never do otherwise.

(You say his name and he erupts into shivers. You lick your lips and he nearly whimpers. You smile at him and gush about the latest journal he'd given you and he's suddenly breathing heavier, suddenly unable to hear anything except the sound of your voice saying I love it.. I love it... I love....)

There’s a part of him that he completely loses control over when you walk into the same room as him, when he sees your lovely eyes fixed on him, when you say his name, when you so much as breath in the same space as him.

(He’d requested you start calling him Kai in private a few months into your ‘stay’, if only because the way the letters roll off of your tongue makes his eyes flutter closed and a sharp exhale sound from below his mask.)

His eyes are snapping to you every time you enter his peripheral, amber gaze appraising you and scanning up and down your body, noticing a new detail every single time - he wasn’t aware you had a mole there, or a small scar here.

(But now, don’t you worry, he’ll remember well.)

And because he’s so unsure of how to manage the new urges and responses that you present him with, he falls back onto his more aggressive traits, the more primal parts of him that don’t really express themselves much in his day to day life taking center stage.

That is, Kai suddenly turns into a jealous, possessive freak because of you – he’s plagued with worries that you’ll leave him, that one day he’ll wake up to find your bed empty, your smile vanished along with your body he was just beginning to crave touching.

(Though he rationally knows the security system of the Shie Hissakai base and the numerous tunnels and henchmen would prove your escape extremely unlikely).

He’s paranoid that you’ll find someone else within the organization that you like more - someone more conventional, friendlier, more intimate with you.

(Just the thought of another man touching you makes Kai’s muscles stand taught, fists flexing and his quirk spiking up out of control, his bloodlust skyrocketing because absolutely nobody should be laying their filthy, disgusting hands on you and ruining you. And, of course, there's the smallest, barely-there twinge of jealousy eating at him because Kai knows he's moving slow, but he's going as fast as he can, and it's just so very unfair. Why can't you just stay perfect and pristine and let him move at his own pace?)

And though it makes him feel stupid, weak, pathetic, he can’t help the way jealousy sits heavy in his stomach as he watches you smile and thank Chrono for dropping by with a new book to read, one Kai himself had heard you mention something about offhandedly, one Kai remembered and went out and personally bought just for you.

He can’t help the way his fists clench as he stares behind the computer screen, vowing to himself that he’ll be the one to deliver you gifts from now on, so that you won’t associate anything sweet or thoughtful with anyone but him.

He hates the way you make him feel (at least, that’s what he tells himself – but even he can’t deny the warmth spreading through his entire chest when you softly murmur thank you, Kai, I love it as he places the elegant, dainty gold necklace with his initials in your palms), but he knows that there isn’t much he can do to change it.

He knows that for all the negative feelings your smile and touch stir up within him, he’d never really choose to let go of his devotion to you because god, do the positive feelings make up for the negative ones a thousand times over.

And so, once he comes to terms with the fact that you do inspire jealousy within him, that he’s territorial over you in a way that makes him feel more animal than man, he’s taking it and running with it – he wants everyone within the Shie Hissakai to understand that you are completely off limits, that you’re property of Kai Chisaki himself, that you are quite literally owned by Overhaul.

He’s threatening undermen, buying you expensive clothing and jewelry and trinkets to make you feel loved and appreciated and maybe even a bit seduced. (And sometimes it works, sure, but there's always something that ruins the fantasy just when you've finally managed to get comfortable - the mystery dinner from Chrono’s tray yesterday, for example, with the perfectly fitting ring set on it that looks much too similar to a wedding band for your tastes. )

He sees you as his possession, an item he can have and own and cherish, and while he does want you to love him, to want him in the same way he wants you, there’s just something about marking you as his, dressing you up in clothing that he bought for you, covering you from head to toe in antibacterial lotion that he chose the scent of, keeping you his sweet little partner that makes him oddly giddy, an honest, genuine happiness washing over him that he hasn’t felt in years.

So really, just let him dress you, feed you, bath you and remind you that you’re nothing without him, that he’s the only one you can trust and should care about, and Kai will be over the moon. He might, maybe, even smile fondly at you and pet your hair and whisper a soft I love you to your sleeping form.

You’re just that special.

Dependent

Although he’s strong and almost infuriatingly independent, once his emotional connection with you develops, Kai is a bit of a lost cause.

You mean absolutely everything to him – his whole life before you revolved around re-establishing the Shie Hissaikai and ending hero society, but once you show up?

Well, it’s still important to create and harvest the drug, to be using Eri and making sure the organization will continue on strong and prosperous, but surely it wouldn’t hurt to take just a small break from vigorously rubbing in some hand sanitizer after a business meeting and let his mind wander to you, to imagine how you’re probably curled up on your bed trying to nap, looking all peaceful and calm and - dare he say it - cute.

It’s not too big of a deal to take a few minutes to drop by your room and check up on you, right?

(Besides, seeing the way you brighten up when he steps into the room makes something in his chest swell with pride; you wanted to see him, didn’t you? Not really, no - it just gets so lonely all alone in the windowless room, but Kai doesn’t need to know that.)

Surely it wouldn’t be bad to take a break from the mountains of paperwork and watch the live footage of you in your room, working diligently at the puzzle he gifted you with the other day, right?

Kai is, for lack of a better term, completely whipped for you – your safety, happiness and health are things that are constantly on his mind. There's always swirling questions of what you’re doing at any given time, when you last ate or slept or used the restroom circling through his head so much it feels like a never-ending loop.

Once Kai gets a taste of how good it feels to care for someone, to have a special person in his life that makes his heart race, his throat get a bit tight and his hands to start sweating, he’s clutching onto it with desperation, doing everything in his power to keep the sensations of happiness, of contentedness, of genuine love blooming in his chest.

He’s addicted to you, and while his every waking thought is either fixated on the drugs or you (though as time passes that delicate balance begins steadily swaying to your favor), his devotion to you only deepens.

But of course Kai is absolutely terrible at expressing how much you mean to him – he’s so emotionally stunted, so unsure of how to approach you and the way you make him feel that more often than not you’ll be left wondering what you did to irritate him. You'll misinterpret the intensity of his gaze and the forcefulness of his, not knowing that really he's just admiring you and too nervous to be speaking with you to regulate his tone well. You'll be left to wonder why he’s always subtly stepping closer to you with each interaction, why he’s always stopping by your room and asking you personal, strange questions.

(Do you prefer cold or warm climates? What’s more upsetting to you – seeing a child or a puppy kicked? What areas on your body are ticklish? Have you ever cried yourself to sleep?

Do you have any previous partners and do you still think of them?)

Honestly, Kai will likely just be one huge mystery to you – he doesn’t want to expose himself and his feelings, and as a result he won’t show any traces of vulnerability to you. You’re left completely in the dark, left to wonder why and how you’re still alive, and when the yakuza boss will decide that you’ve lived past your expiration date.

Sure, he does buy you gifts; jewelry much too expensive for your tastes, dresses and skirts that accentuate your form in darker colors (he’s particularly partial to greens and golds – always dressing you up in gold necklaces, gold heels and sleek jade dresses that dip just a bit too low on your chest), occasionally a bouquet of flowers in your favorite colors that he insists brighten up the mood a bit.

(Though you don’t have the heart nor the courage to tell him that a bundle of roses sitting in a vase in the corner of your stark white room doesn’t make you any more comfortable there.)

Sure, he spends hours upon hours upon hours behind the computer in his office staring at you through the screen, the many cameras and audio bugs placed around the room picking up your every action, word and movement, his wide eyes feasting upon your innocent, perfect form as he simply takes in the beauty that is you, the feelings of love, adoration and utter want swimming in his chest intoxicating him.

Sure, he’s killed guards left and right for staring at you for a beat too long, for making some crude, disgusting joke about how they’d love a piece of you, that Overhaul’s too uptight, bet he doesn’t even fuck her – what a waste, she needs a real man to show her how its done.

Sure, he spends the majority of his time obsessing over you, doing daily check ups on your health and your safety, but Kai won’t ever display a moment of weakness to you – he only says he loves you when you’re asleep, laying so gracefully across your bed, his form seated at the edge of the mattress while he lightly strokes your cheek, his mask discarded onto your nightstand as he leans down, closes his eyes and takes a deep inhale of your scent, pressing his lips ever so lightly, softly, tentatively against your forehead.

He doesn’t want you to understand how much hold you have over him – because if you did, Kai is absolutely sure that you could manipulate him into getting whatever you want with just a simple kiss and whispered word of affection.

After all, Kai Chisaki needs you, and although he’s embarrassed by how much you mean to him, how crazy you make him and how absolutely obsessed with you he is, he wouldn’t change a single thing.

After all, he’s never been able to love someone, to touch them and protect them and desire them, and he’ll be damned if he ever loses you.

DEALING WITH RIVALS:

Kai is, to put it simply, insanely possessive over you; you’re his girl, the only one he can love and touch and really feel happy around, and as a result he absolutely refuses to allow any other man to get even remotely close to you.

It’s a combination of jealousy and deeply rooted insecurity about his romantic skills that makes him so quick to snatch you away from other men.

He won’t ever admit it, but he’s very aware that he probably wouldn’t be your first choice, that his issues with intimacy and expressing himself and the fact that he kills on a daily basis likely does nothing but push you away, make you more hesitant to fully give yourself to him, to actually love him.

But instead of communicating with you, of putting himself in a position where you could actually see how much of a mess you make him, Kai instead decides that isolating you from every other man in the complex is the best solution.

This fear only serves to make him more strict on limiting your contact with every other person on Earth who isn’t him, every other man that could possibly draw your attention, that could make you forget about Kai and instead fall heads over heels for them.

He’s methodical in his approach to keeping you utterly and completely his – making sure that your contact with others is incredibly limited, that you understand the consequences of becoming too chummy with anyone but himself.

Because you’d have to be his captive before his feelings for you even really form, he doesn’t have to worry about any men that he doesn’t know approaching you, fighting for your affection and love.

He only needs to consider the possibility of one of the very few people he allows you to have contact with – namely, a select group of the eight bullets, himself and Chrono.

It’s an ease to his mind to know that he’s really only competing with a few other guys, and although it makes him feel stupid, pathetic, weak to be comparing himself to someone like fucking Rappa, there’s a certain part of him that can’t help but wonder if it’s really someone more like him you’d like – muscular, social, not hesitant to touch you, all of the things he really isn’t.

It’s stupid and he knows it, but as he stares into his mirror with an expressionless face, looking at his nude body and his hands that can so easily take and give life, there’s a certain amount of insecurity settling in his chest.

Obviously, you don’t really have a choice in who you spend your time with, who you’re forced to depend on, who you’re destined to be with until your dying breath, but Kai really truly would prefer you to want him, to actively be choosing him.

And when one of the few people he lets have contact with you starts pushing the boundaries too far, getting a bit too friendly?

Well, all of those pushed down insecurities and destructive thoughts are rearing their ugly heads, forcing him to take measures he would prefer to not deal with, to not have to feel such terrible, sick things in his heart as he watches you laugh and smile.

You’re his, whether you like it or not, and Kai will absolutely make sure the fact is drilled into your pretty little head, even if the methodology is less than tame.

When he spots Setsuno leaning on the doorframe of your room, smirking down into the space while your lovely, tantalizing voice gushes about some show you used to love watching before you got kidnapped, immediately he’s scowling, thin eyebrows drawing taut as he realizes how fucking close Setsuno is standing next to you, how his gaze is aimed directly at you, how you’re just letting him stare.

Kai’s pissed, and as his footsteps grow harsher, more distinct against the cement of the underground hallway, he’s nearly growling.

He hates when he gets like this – it’s so painfully obvious how much of an emotional hold you have over him when the jealousy is seeping through his every pore, when he’s nearly driven insane just by another man looking at you.

It’s infuriating that something as simple and weak as you are able to make him a complete mess with just a few actions, just a few smiles and looks directed towards others.

It’s infuriating, but as he approaches Setsuno, the anger at himself is drowned out by the rage he feels towards his underling – immediately he’s clearing his throat, piercing eyes staring right at his subordinate as he interrupts the conversation, letting out a surprisingly calm sorry to interrupt, but tests are scheduled for right now. Wouldn’t want her to be late, would we?

And although Setsuno holds respect and genuine awe for his boss’s abilities, a twinge of fear climbs up his spine, making him hastily nod his head and return back to his station a few hundred feet away, nervously awaiting what he’s sure won’t be a pretty sight whenever Kai is done with your tests.

All throughout the blood draw that day, he’s tense, not really responding to your questions as thoroughly as he normally would, not paying as much attention to you as he’d like to.

(He’s staring at you, yes, but he’s sort of staring through you - not as observant as normal, not with the same concentration as normal, as if he’s counting your eyelashes or memorizing every blemish and pore on your face.)

Instead, he’s thinking of exactly what he’ll be doing once he safely escorts you back to your room, once he makes sure that you’re safe and sound and completely unaware of what he’s about to do.

And once your door is closing, he’s immediately scowling and stomping over to Setsuno, approaching the man with a deadly glare and scolding him in a voice so eerily calm that it has the other man gulping.

You know your place – you aren’t to look at her, touch her, speak to her, be anywhere near her. So tell me, what did you do today, Setsuno?

And when the other man can only respond with the truth, Kai won’t hesitate to disassemble him a few times – each with an interval longer and longer, sometimes not assembling every limb back together until it’s just barely not too late, letting him feel the excruciating pain of his arm being ripped off again and again.

There’s this twisted, maniacal look on his face as he does it - like he’s enjoying hurting Setsuno, like with every time his leg is ripped from his body, he’s ripping away some of the damage that him talking with you caused, ripping away any semblance of attraction or even a friendship between you two.

If Setsuno wasn’t busy in excruciating agony, he’d almost be scared his boss’s expression.

Kai’s pissed, and it’s only after twenty or so rounds of assembling and disassembling that he’s finally calmed down – though he won’t leave without hearing the words I’ll never come near her again, I promise! She’s yours, Overhaul, all yours!

And once he does, he’ll only firmly nod, leaving Setsuno on the cold ground, assembled yet terrified, as he retires back to his office to review the last hour’s worth of footage from your room.

Jealousy isn’t a pretty look on Kai, and he holds back absolutely no restraint when he feels that his claim on you is being tested.

So when Setsuno, one of the only people here you feel you can call a friend, begins avoiding you like the plague, don’t be surprised when Kai shows up, telling you how Setsuno’s just strange like that, always changing his mind back and forth. Don’t worry about it – I brought you a deck of cards, would you like to play?

TAKING HIS DARLING AWAY:

To really catch Kai’s attention, a very specific set of circumstances must occur. You must be quirkless, a civilian, and he must have stolen you off the streets for testing. Only then, once he’s got you under his grasp already, do his feelings begin to form, in all their horrible and wonderful glory.

But, because had stolen you away before his feelings for you even manifested, there really isn’t a forming-the-obsession-and-stalking-before-kidnapping phase for him.

You’re already at the Shie Hissaikai’s base, already under his control and grasp, and as a result you’re already accessible to Kai, already close to him and so very vulnerable to his wants and whims, to him being around you as much as he pleases. He doesn’t experience any sort of longing to steal you away, nor does he have any kind of dilemma on kidnapping you.

However, because of the way in which Kai got to know you, it creates a bit of a unique situation as his captee – you’ll find as his feelings grow and develop, as he becomes more and more dependent on you, that your surroundings seem to change, that you periodically get moved to different rooms, different spaces in which you spend the majority of your time.

The rooms get progressively nicer, larger and more private, soon getting to the point where you even have a small kitchenette in the corner, where you’re able to prepare little snacks and food items.

(Kai must always be present in the room during your little cooking episodes, however – you need to be eating healthy, making sure that you have a balanced diet, though the minute that you turn around excitedly and ask him if he’d be willing to sample whatever you made, he’s fighting a blush and nodding stiffly, trying to calm his racing heart and quell the thoughts of how you look so much like a lovely, domestic wife cooking for him…)

You won’t be sure of why you’re gradually being treated better and better, getting spoiled with gifts that you didn’t ask for, spending time with Kai in quantities that make you cock your brow but shrug, knowing that if you confront him it’ll likely be more trouble than it’s worth.

You won’t know, but Kai sure as hell does – he wants you to like him, to love him and need him, and as he progressively decides to upgrade your living space until your room is right next to his own, allowing quick and easy access (and thin walls, of course) it helps quell his desire to be near you every moment of the day, to be on your mind just as constantly as you’re on his.

And really, it’s only a plus that he can press his ear to the wall and listen to you breath at night (he moved his bed to be right next to yours, only the thin wall separating the two of you), or that he can basically speak to you through them - even as much as it terrifies you.

It’s better this way, really - it helps quell the fear of you somehow slipping through his fingers.

As his captee, your experience with him really depends on your own behavior and tolerance – the only way you would’ve ever caught his attention is being a mix of quirkless and kind, reaching out with soft, understanding words rather than screaming, fighting or cursing him out like every other test victim he’s picked up.

And so, if you keep this behavior up, Kai honestly isn’t too terrible of a captor; he’s relatively clear on what he expects from you, relatively easy to please as long as you follow his every command and keep talking to him about your day, about yourself, asking him how he’s feeling at any given moment.

He’s possessive and controlling to an almost staggering degree, yes, but his expectations are crystal clear, if a bit sterile.

And so, if you can put up with him placing cameras in your room to keep an eye on you every minute of every day, of him regulating what you eat, when you bath, how you sleep, you’ll be fine.

If you can deal with him bringing you into his office for hours on end, just having you sit and read or chat to him while he works simply because your presence is enough to help ease the stress of running the organization, then you’ll be just fine.

If you can deal with the daily check ups that progressively get more and more personal (it started with a simple blood draw, checking your temperature and an eyesight test, then gradually moved in a full body examination over your clothing, then without the clothes, then with you sitting in what appeared to be a gynecologist’s chair), then you’ll be just fine.

It’s about tolerance with Kai – if you’re patient and generally obedient, life under his rule will be surprisingly easy, even if loving the man who kidnapped you isn’t as simple.

As his feelings grow, Kai honestly gets a bit clingy; you calm him in a way he didn’t know was possible, the warmth spreading through his chest foreign and strange yet addictive as you place yourself on the leather couch opposite his desk, trying to ignore the way his amber eyes pierce through you, or the way there’s a very obvious tent in his pants when he reaches across his desk to place a strand of your hair behind your ear.

He’s wanting to visit you constantly, though he rations himself a bit if only to keep some semblance of self-control.

And though he wants to be constantly touching you, feeling your soft skin against his own (that he knows he can touch with no penalty, and since the day you willingly held his hand, he’s been harboring the fantasy of hugging you, resting his hands on your waist, cupping your cheeks, running his hands through your hair, kissing you…) and just being around you, his awkwardness when it comes to opening up to you persists even once he’s absolutely sure that he’s in love with you, that he wants to spend the rest of his life with you by his side.

It’s just not that easy to tell you that his happiness depends on you now, that you’re on his mind in both the waking and sleeping world, that he’s devoted to you in every sense of the word – and so, he tries to show it to you by making sure that you’re in pristine health, that you’re spoiled with the most lavish gifts and items and goods that he can find, that you’re treated like a queen by everyone in the Shie Hissaikai, or else they’ll have hell to pay with Kai himself.

He hopes that you might understand via these methods, as it’ll take him years to fully admit to you how much you mean to him, for him to feel comfortable actually telling you those three little words he’s thinking as he stares at your sleeping form, as he watches you smile while you read a particularly happy part of your new novel.

He loves you, and as long as you stay good and obedient and personable with him, life under Kai’s rule won’t be too difficult – removed and odd, yes, but as long as the feeling that you’re some thing he’s studying and obsessing over doesn’t bother you, then you may even find yourself being okay with the locks on your doors, the threats of his men down the halls.

It’s okay, you tell yourself as he traces a single, ungloved finger across your collarbone.

It’s okay, you’re not dead yet, you’ll be okay.

PUNISHMENTS:

Despite the general softness that Kai possesses for you, he has absolutely zero patience when it comes to you misbehaving.

He’s still the boss of the Shie Hissakai, a yakuza member who’s used to being completely obeyed, to killing rebels with a flick of his wrist.

He’s still a criminal, even if you smiling at him leaves him flushed under his mask, and the moment you step out of line, he has no problem reminding you of that fact, no problem making it explicitly clear that he’s the one in charge.

He’s very much a worshipper (though more on the down-low, if only because a small part of him is still absolutely mortified that he’s fallen so deeply for someone like you), though despite seeing you as a bit of a goddess, Kai doles out punishments right and left.

Of course, there’s always the omnipresent threat of his quirk hanging over your head; you’ve been told by Rappa how excruciatingly painful undergoing a disassemblement is, and if the muscular, violent Rappa is saying that?

Well, there’s no doubt in your mind that you’d be almost glad to be dead after such an ordeal.

You’re painfully aware of just how much power Kai holds over you; how his every whim and emotion could potentially spell your death, how any small misstep (or lack thereof, to be honest) could result in your blood splattering across the walls.

And call it self preservation, but in the face of a violent, painful death at the Shie Hissakai boss’s hands, obedience begins coming quite naturally to you, as does being hyper aware of every little thing you do.

It doesn’t take long to figure out that Kai is very much not a person you want to cross, as just a few simple demonstrations of his quirk in action on unlucky yakuza underlings are almost violently shoving the truth in your face.

It becomes your mission to be the picture-esque captee, to not give him any trouble and follow his every command to a T.

After all, Kai is a difficult man to please, and while your mere presence relaxes him, makes him happy in a way he can’t remember ever experiencing, he’s not afraid to do what he needs to in order to make you understand that you will be following his every word.

Along with the ever present threat of him using his quirk on you (something which Kai has sworn he will never do, if only because he’s terrified that in doing so you’ll lose some of the precious purity you harbor), he has a tendency to use other methods to keep you in line via fear.

Killing is a part of his daily routine, and while he doesn’t particularly enjoy ending someone’s life, it’s something that he sees as necessarily in order to keep his underlings in line – and when you’re in need of a punishment?

Well, who is he to deny such wonderful timing and opportunity?

And so, when he drops by in the evening to bid you a goodnight, he can’t help but smooth his shirt down slightly and run a hand through his hair outside your door, feeling like a teenage boy with how he so desperately wants to look good for you, to impress you.

He opens the door without a knock, amber eyes flicking across the room to find you sitting on the edge of your bed with the latest book he bought for you perched in your hands, your eyes staring raptly down at the yellowed pages.

You’re so pretty when you’re focusing on something, Kai’s found, and as he watches you read with an air of complete concentration, he can’t deny that a small pang of irritation eats away at him.

He’s here, present inside your room, having sped walked through the hideout to reach you in his haste to see you, and yet you’re ignoring him in favor of a book?

It hurts a bit, if he’s being honest, if only because shouldn’t your attention be solely and completely focused on him, not some mish-mash written down on a page?

His brow twitches as he clears his throat, watching the way you jump and immediately meet his gaze, surprise flitting across your features.

You make some comment about not seeing him that only makes Kai feel worse, the distinct realization that you don’t just sense his presence as he does yours hitting him.

But before you really have any space to say more, he’s telling you to follow him, that there’s someone he’d like you to meet, which you do, hesitance eating away at your gut at the irritation swimming in his eyes.

He’d meant to have a simple conversation with you, to bask in your presence and maybe and lightly hold your hand (something that still makes him flush from the tips of his ears to the base of his neck, though he’d rather die than admit it), but now that you’ve made such a clear choice to ignore him, to prefer your book over him, he’s deciding that the man he’d planned on killing tomorrow for having made openly insubordinate comments about himself and Chrono would be receiving his punishment early, with another set of eyes viewing.

You know immediately that something is off the minute he closes the door behind you, the bald man tied to the chair in the center of the room staring wildly at you, his dark eyes pleading silently as the gag muffles any words spilling past his lips.

You can’t hide the shock and fear on your face, terror at what exactly Kai plans to do eating away at you, though when he moves to stand next to his victim you can only harshly swallow.

Tell me: do you know why I might be angry at you?

His voice is deceptively calm, apathetic yellow eyes boring into yours as you stutter out a weak ‘no’, genuinely at a loss as to why he’s upset. Kai can only frown, humming lightly before tugging a glove off, making the man beside him squirm.

I bought you those books for entertainment purposes yes, but don’t you know it’s rude to ignore others in favor of fictional characters?

You’re freezing at his words, the realization that he’d been angry at you for not noticing him earlier hitting you like a ton of bricks.

Really, I know you’re smarter than that, so I’m letting you off easy this time. But, don’t think you’ll be going completely unpunished – it’s just that Yamaro here just so happened to be willing to take the punishment for you.

The man’s eyes go wide, his squirming and struggling more desperate than before as kai unceremoniously taps a finger against his bare hand, the man immediately exploding in a shower of blood and guts, making bile rise up the back of your throat.

Kai clicks his tongue, shuddering at the splash of blood against his arm, but those cold eyes stay focused on you as you gag and look anywhere but at the sight in front of you.

It’s your fault, (f/n). If you hadn’t been so rude, he’d still be alive. Do you understand your lesson now?

That of course is not true, but Kai won’t tell you – not when you’re nodding, frantic in your desperation to get out of the room, and when Kai nods a few seconds later, opening the door, you breath heavily, staring at the cement ground in fear and shock.

The guilt is overwhelming, the idea that you’re responsible for that man’s death weighing heavily in the back of your mind, exactly as Kai hoped for.

He’s silent the rest of the night, dropping you off at your room without a word, and when you awake the next morning and he steps inside your room, you’re immediately throwing your book to the side, forcing a smile and a chirp of good morning, Kai. How are you?

It’s a bit of a dirty method yes, but Kai couldn’t care less – obedience is what he wants, and he’ll get it from you, even if he has to lie and kill right in front of your eyes.

Anything to keep you in line and his, after all.

OVERALL DANGER:

8/10

In all honesty, the danger that comes with being Kai’s darling is that there is truly, genuinely no escaping him.

He’s so thorough in his planning, so steadfast in his organization and meticulous thought put into every possible scenario that could play out with you that your future is quite literally sealed the moment he feels the trace edges of his feelings form.

Kai is, without a doubt, not a good man – his devotion to his organization is commendable, but his moral compass is deeply skewed, the mere existence of Eri enough to prove that just as he’s willing to do anything to ensure the success of the drugs, he’s willing to do absolutely anything to make sure that you stay by his side, that he gets to keep you like a prized possession that only he gets to gaze at.

You’re something he revers, his dedication to you unparalleled, and because of Kai is absolutely making sure that you’re spoiled, that he rewards his dearest, as he calls you, with the finest jewelry, the best food and the strictest schedules he possibly can in order to keep up your perfection, to keep you pristine and healthy.

He loves you, in some sick, obsessive way, and poor, poor Kai is so unused to having someone with whom he holds such deep, desperate emotional connection to that he’s honestly floundering a bit.

And lucky lucky you gets to experience every drop of cruelty, desperation and yearning the Shie Hissakai boss has to give you – and receive you shall.
