A/N: To @xoxothekitsunehashiraxoxo :) I hope I did your request justice, and thank you for requesting! Also, since it wasn’t specified, I made it into hcs. Hope you don’t mind! 🙃 

Warnings: a little bit of angst about Genya’s past, Genya being distrustful of the reader until a certain point, ooc Genya (he sounds like Bakugou again whyyy 😩) and I wrote the reader’s hair red. Idk if that’s ok? 

When you first meet Genya, it’s in the infirmary of the butterfly mansion; he’s badly injured, just having barely survived a failed mission with an equally skewered conscience, and you- well, you’re searching for someone new to terrorize. 

He tells you to “Go bother someone else goddammit!” and he’s a bit… he’s a bit bothered when you smile instead, a wide, foxy grin he doesn’t like in the slightest. 

Where you’re initially intrigued by the mystery of his last name and the gap between him and his brother, Genya’s a little bit mystified by you; you with your mischievous grins and your coral-red hair and cunning mind like the very embodiment of the Kitsune Hashira and a pet fox you literally call Fox (“Genya-kun, this is Fox! Fox, this is Genya-kun.” “Hah? You literally call your fox Fox?!” cue the cursed thing jumping on him and he did not scream like a girl, shuddup!), and your status of Hashira that makes him sort of envious because, well, you can’t be much older than him, right? And yet you’re closer to Sanemi than he’ll ever be, probably earned his respect too, because you’re wonderful and perfect like that, and it’s everything he’s ever wanted. 

And from that day onwards, you sort of just… stick around, he guesses- a constant in his life if there ever was one, smiling at his blatant insults and finding loopholes through his words and constantly flustering him and touching his scars with a gentle hand, and smiling at him like you actually, really mean it, like you actually think he’s worth something, like he’s actually good. 

And at first it’s infuriating, because you’re just distracting him with your pretty words and prettier smiles and why does he find your words and your smiles pretty in the first place?! And he hates it, hates you. 

But you’re both persistent like the devil, and as patient as a Saint, and you’re insistent on becoming his friend, so you play the long game. 

And then slowly, slowly, your constant efforts whittles his anger away, and slowly, it becomes slight annoyance and then familiarity and your relationship becomes something  suspiciously like friendship and the promise of something more.

Genya finds you a steady presence by his side, and he begins to take a strange comfort in that- knowing that while the world may change, you’re the one thing in his life that will always stay constant. 

You remind him of the good that’s left in the world, of the family he lost, of why he became a slayer in the first place, and with you, Genya relearns what he had forgotten; that there was good left in the world, bonds strong enough not to be weathered by time and love true enough to withstand the weight of eternity. 

And with you, when he learns that you’re only there to help, when he learns not to push you away anymore, Genya learns to smile- albeit a tad roughly- around his scars, learns to laugh at your terrible jokes and pet Fox with an gentleness that’s unusual for him, and he learns how to appreciate the small things; like the way the sun catches in your red, red hair in a way that makes it halo around you like a crown of flames, the way your eyes shimmer with an galaxy of stars in the light, the laughter in your voice, and the sweet curve of your mouth that he’d like to kiss one day. 

(Under your care, he learns how to love again without the reminder of all the hurt and the pain, and this time, with you around, Genya’s determined not to forget it again.) 

Warnings: probs super Cringe cus it’s my first writing yandere, definitely ooc Genya (ngl he sounds like Bakugou 😭), possessiveness, kidnapping, yandere behavior, different forms manipulation, mentions of being locked inside a house, chained, etc etc, you know the gist. 

When he first meets you at the selection exams, Genya finds you insignificant, another hopeful face in a sea of others- an obstacle in his path. 

Then that indifference to your existence turns into annoyance because you’re like a mosquito he can’t crush, constantly on his heels and by his side, chattering on and on about one whimsical thing or the other, and although he’s made it sure that you know he “doesn’t want your stupid friendship goddamnit!” you just smile gently in response, undeterred by his anger. 

Still, for some reason, you stick by his side through thick and thin despite his insults and his unwarranted anger and his rough edges, and slowly, the annoyance turns into expectation.

As slow as it is, Genya begins to expect your constant  presence by his side, he begins to expect the shape of your mouth curving into a smile just for him, and he, begrudgingly, begins to accept it. 

Then the acceptance begins to swell into something more, something like attachment and something else he can’t yet discern. 

You begin to make him feel… different.

You with that soft voice and meek eyes, you with that gentle touch and saccharine sweet smile that makes his heart wrench for someone reason, and the first thing Genya wonders is, is he sick? 

The answer is yes, yes he is. Lovesick for you, that is. 

Genya doesn’t accept it, at first, doesn’t want to ruin what he already has with you, but he knows that these feelings won’t go away either. 

So he shows his love for you in subtle ways. 

Whenever Genya sees something you’d deem cute, you’d find it by your bedside table by the next morning, and you know it’s him, judging by the furious red dusting his cheeks and ears when you next see him, and you wisely decide not to poke him about it, so instead you just grin, brighter than before. 

He’ll share his food with you if he knows you skipped a meal, and whenever you’re feeling down, he’ll try his best to cheer you up, so “quit sulkin` around!” 

And although he looks disinterested to any outsiders, Genya makes sure to hang onto your every word as you talk, even though it’s probably about cute, pink things you like or some other airy topic he probably won’t understand much. 

And then the lovesickness bleeds into something unhealthily darker. 

Genya genuinely believes you’re not something he deserves, but he’s selfish, and he wants to keep you for himself, because he knows good things in his life are fickle, and never last long. 

So when he sees you chatting with Tanjiro, with that same soft, tender smile that’s meant only for him, Genya decides that while he’s not worthy of you, nobody really is. 

Nobody but him are allowed to see you. To touch you. Nobody but him are allowed to see the way you smile, or hear the sound of your laughter. 

You are his, and his alone, so he wards off anyone else who wants to talk you, all bared teeth and jagged scars and growling voice. 

See, since it’s not an if when you’ll get into fights about his possessiveness, and rather a when, he’ll weasel his way out of it by manipulating you in whatever way he can. 

He will lie, guilt-trip, gaslight you and victimize himself, and since Genya is quite insecure- in himself, in your relationship, half of it is not even a lie. 

He’ll also probably use his guilt about the whole Sanemi incident to convince you be with him. 

And that’s not even the worst of it. 

Since you’re both demon slayers, and your soft-spoken demeanor makes him think you’re a little bit weaker than the average slayer, he’ll try to get you to quit. 

And when that doesn’t work, and you get injured in a mission, Genya takes it upon himself to, in his mind, protect you. 

(He knows you won’t willingly quit the corps so he’ll knock you out if he has to, and keeps you in a house he’s made his own, just for this reason only.)

You’re granted the freedom to do whatever you want to  inside the house. 

Since he doesn’t have any estates like the Hashiras, he will take you outside with him by his side so you won’t be able to escape, his hand resting on your lower back or on your arm, a reminder that you’ll never be able to escape, not with him around. 

And, well, if he finds anyone else trying to help you escape…

He’ll make sure they’re not around to help you out a second time. 

Overall, you have no chance to escape, because he’s barred the windows, made sure to lock all the doors in locks strong and heavy enough for you to not be able to break. 

Hell, he’s even chained you inside your room, just for an extra measure. 

This is all to ensure that, you’ll be by Genya’s side forever. 

“I love you, I love you, I love you, goddamnit! Why can’t you understand that?! This is all for you. This is all for you, so why are you looking at me like that?!”
