Omg I kept seeing your posts on my feed and yk it was only a matter of time before I started ITCHING to request.

So uhmm yeah 😅. I'd like to request for rin x reader where reader suggests (begs, forces even) rin to wear matching Halloween costumes. Rin eventually relents and they wear matching clothes idk. The characters they dressed up as is up to you lol 😭😭. This can be a multi character headcanon thing too if you want btw !!

“𝐭𝐡𝐚𝐭 𝐛𝐨𝐲 𝐢𝐬 𝐚 𝐦𝐨𝐧𝐬𝐭𝐞𝐫𝐫𝐫”

a/n: i love this request!!! i want it to be halloween season again already

and yes the title is based off the lyric from “monster” by lady gaga that is my FAVORITE lady gaga song of all time UGH

i couldn’t help it so i made a oneshot with rin + headcanons ft. shidou ryusei, isagi yoichi, kaiser michael, & mikage reo (yes i am willing to add another part to include other faves, but please request it so i can see it and don’t forget!)

"c'mon, rin," you whine, dragging out his name with a dramatic pout, "pleaseee? just this once?"

rin's arms are crossed, his blank stare fixed on you with the same deadpan expression he usually reserves for reporters asking dumb questions. he doesn't even dignify your pleading with a response, just slowly blinks at you, like he’s waiting for you to come to your senses.

"you can’t seriously be this against it," you groan, standing on your tiptoes to hold his face between your hands. you squish his cheeks slightly, making his lips pout involuntarily. "it’s not gonna kill you, rinnie. halloween is supposed to be fun. why are you so against matching costumes with your super cute, super loving girlfriend, huh?"

he stares at you in bored silence. your thumbs press into his cheeks. he blinks again.

"i’m not dressing up," he finally mutters through squished lips, voice flat and unwavering.

"liar," you accuse, leaning in closer, eyes narrowing. "you’re just trying to act all aloof and tough, but deep down you wanna wear stupid little couple’s costumes with me."

he exhales sharply through his nose, gaze unamused. "no."

"yesss," you counter, squeezing his face harder. "isagi would do it for his girlfriend."

rin’s eye twitches. "don’t bring him into this."

"shidou would do it too."

he stares you down. "shidou would show up naked."

"okay, true." you grin mischievously. "but isagi would do it."

rin’s entire jaw clenches under your hands. you feel it. he stares at you, hard, like he’s contemplating if breaking up is worth not having to wear a costume.

"... fine," he mutters, glaring at you through his lashes, voice heavy with defeat. "but if you make me wear something humiliating, i’m leaving you and going home."

you beam. he already knows he's doomed.

𐙚

cut to halloween night, and rin is seething.

standing before you, arms crossed and exuding enough grumpiness to scare off trick-or-treaters, is rin itoshi dressed as howl pendragon.

he’s wearing the loose, cream-colored poet shirt, unbuttoned just enough to show a hint of collarbone, with its wide, billowy sleeves practically falling off his shoulders. the black pants are fitted, almost too fitted, highlighting his long legs and lean frame. and, of course, he’s wearing the signature dangling earring, which you personally clipped on because rin refused to touch it.

his black hair falls naturally over his forehead, slightly tousled but still unfairly perfect, and when he gives you a deadpan stare, the faintest sway of the earring makes your brain short-circuit.

"you’re so hot," you say instantly, still marveling at the sight of him.

"shut up," he mutters, clearly annoyed, yanking the sleeve of his shirt higher on his shoulder, only for it to fall back down again.

you grin, reaching over and gently pulling it back down. "nah, leave it. it looks better this way."

rin glares at you. "i hate you."

but the tips of his ears are red. and you definitely catch the way he subtly tugs you closer by your wrist, lacing your fingers together.

meanwhile, you’re dressed as sophie, your hair styled in soft waves. you’re wearing a modest blue dress with long sleeves, flowing down to your ankles. you look soft, ethereal. like you stepped right out of a studio ghibli frame.

and rin, despite his grumpy facade, can’t stop glancing at you out of the corner of his eye.

"you look like you wanna kill me," you tease, poking his side.

"i do," he deadpans, scowling at the couples flooding the party venue with their half-assed cat ears and vampire capes. "you made me wear this."

"and you look stunning," you grin, reaching up to brush a strand of hair from his face. "like... stupidly handsome. if howl was a pro soccer player, he’d be you."

rin’s jaw clenches slightly, eyes narrowing. but his grip on your hand tightens just a fraction.

as you drag him toward the party crowd, you catch the stares. people are gawking, not just because of the spot-on costumes, but because rin itoshi, the notoriously aloof, "i’d rather eat glass than socialize" soccer star, is walking around in a flowy, romantic shirt, holding your hand like it’s the most natural thing in the world.

someone even mutters, "why does howl look like he’s gonna deck someone?"

grinning, you stop him in the middle of the dance floor and tug him down slightly by his collar, leaning close to his ear.

"thanks for being my howl," you whisper, lips brushing his skin.

rin exhales slowly through his nose, eyes lidding slightly as he looks at you. his expression softens, just barely. but instead of responding, he dips down, closing the space between you and pressing a slow, deliberate kiss to your lips.

when he pulls back, he leans close to your ear, voice low and raspy.

"you owe me for this," he mutters. "like... a lot."

your breath hitches slightly, but you manage to smirk. "oh, i’ll pay you back, alright."

he huffs softly, pretending to be annoyed. but when his hand slides down to rest against the small of your back, tugging you close, you know he’s just as down bad for you as you are for him.

even if he refuses to admit it.

shidou ryusei – hades and persephone

the moment you suggested matching halloween costumes, shidou was instantly on board. no begging needed. he was thrilled.

he lets you pick the couple’s theme and doesn’t even care what it is. you could’ve said "let’s be ketchup and mustard" and he still would’ve said yes.

you end up choosing a hades and persephone duo – him as hades, you as his goddess.

he goes all out: all-black suit, messy blond hair slicked back, black gloves, and faint red eyeliner smudged around his eyes to give him a more devilish look. he looks unfairly hot and knows it.

constantly smirking and calling you "my little goddess".

at the party, he pulls you into his lap and slings an arm over your thigh the entire time.

"you’re not going anywhere, babe. you’re my prisoner for the night, remember?"

dramatic, possessive, and constantly finding excuses to kiss you.

"persephone never escaped hades, y'know? you’re stuck with me forever, baby."

and you just know he makes you rewear the costume after the party.

isagi yoichi – spiderman and gwen stacy

isagi is… confused at first. like, why do you even want to match costumes?

"baby, it’s just halloween, not our wedding."

but the second you flash him the spiderman and gwen stacy costume idea, he’s in.

he shows up in the classic spidey suit, and you have to admit, he looks fine as hell in that skin-tight material.

you, as gwen, wear a white and black bodysuit with pink and teal webbing accents and a cropped white hoodie.

the second you put it on, isagi cannot stop staring. like, jaw slack, brain short-circuiting.

"holy shit, you’re so hot. wait, is this how you feel when you look at me?"

at one point at the party, he does the upside-down spidey kiss for fun. you both nearly fall over, but it’s worth it.

"we should wear these costumes every year," he grins, pulling you into another kiss.

kaiser michael – vampire lord and vampire bride

kaiser was immediately smug when you suggested matching halloween costumes.

"oh? you want everyone to see how good we look together? can’t blame you, schatz."

the two of you dress as a vampire lord and his bride – kaiser in an ornate black and red velvet suit, complete with a high collar cape and fake fangs.

he even slicks his hair back and adds subtle red contacts for the “drama.” you wear a blood-red corset dress, with lace gloves and a delicate choker, looking absolutely ethereal.

kaiser doesn’t shut up about how hot you look.

"scheiße… you’re gonna make me forget my own name, baby."

practically clings to you all night, leaning down every two seconds to brush his lips over your neck as if he’s about to "bite" you.

"mm, i think i might keep you as my blood bag forever, yeah?"

he refuses to take the costume off when you get home, because he’s having way too much fun.

mikage reo – jack and sally (the nightmare before christmas)

reo is excited the second you suggest matching costumes.

"hell yes. we’re going all out, baby."

you pick jack and sally from the nightmare before christmas. he gets so into it.

he shows up in a pinstripe suit, black gloves, and even paints his face white with black shading around his eyes to complete the skeletal look.

you’re dressed as sally, wearing a patched dress, colorful stitches painted on your arms, and pale makeup.

he spends the entire night making puns about being "dead serious" about you.

"i’d cross entire graveyards just to be with you, baby."

constantly holding your hand and twirling you around because the costumes are too cute not to show off.

halfway through the night, you catch him staring at you with this lovesick look and he just smirks.

"you know you’re stuck with me even in the afterlife, right?"

you roll your eyes, but your face is flushed.
