OsaAka are hosting a literary themed Halloween party, and Atsumu's /sure/ this is his chance to impress Shouyou and finally ask him out.

Shouyou once told him how he likes Zoro from One Piece, so Atsumu's pretty sure he'll dress as the swordsman

for the party, and it's critical that he picks a costume that matches Shouyou's. Not only does he want to show how compatible they are, he also wants to show that he's been listening to Shouyou, for real, and takes his interests seriously enough to want to share them together.

Atsumu binges the anime for weeks, and before he even reaches the midpoint he knows /exactly/ what costume he should wear--the chemistry between Zoro and Sanji is undeniable! A quick google image search produces /so much/ hot fanart Atsumu knows he's made the perfect choice.

(He's a little scandalized, too, like--the incredibly sexy things those artists have Zoro and Sanji doing to each other are--! 😳🥵🥺🔥‼️)

Not that he's deterred even a bit--it's the obvious choice, especially since Sanji is /blond/, and has great legs--it's perfect!✨

When Shouyou comes up to him after practice and oh-so-casually asks what he's planning to wear to OsaAka's costume party, Atsumu positively /glows/.

"Can't ruin the surprise now can I?" he replies, grinning impishly.

"Awwww," Shouyou pouts, gently kicking him in the shin. "Won't you give me a hint at least, Atsumu-san?!"

Atsumu pretends to think long and hard about this, enjoying how Shouyou bounces on his feet imploringly.

"Okay, okay, /one/ hint," Atsumu laughs, bending down with his hand cupped around his mouth. "Gonna be a reeeeeeally strong, cool guy from a popular manga series."

Shouyou's face lights up, eyes sparkling. "Ooooo!"

"But that's all I can say, Shouyou-kun." Atsumu winks.

Shouyou smirks, tilting his head as he looks up at Atsumu. "Can't wait to see it," he says, turning around and looking over his shoulder as he heads to the locker room.

When he's gone Atsumu spins on his heels, muffling an excited scream with his towel before chasing after him.

He can't /wait/ for Halloween!

Right after practice, Shouyou bikes directly to Onigiri Miya in the hopes of catching Osamu at a free moment.

The restaurant is packed and buzzing, but Shouyou spots Osamu coming out from the kitchen and makes a beeline to intercept him. When he does, he finds himself right

beside Akaashi who's in the corner seat of the onigiri station.

Hinata greets them both excitedly. "Looking forward to your party!"

Osamu puts Akaashi's order down in front of him. "Glad yer gonna make it."

"Yeah of course!" Shouyou grins. "Actually I have a question..."

"What's that?" Akaashi asks.

"Well, um," Shouyou bites his lip, glancing away. "Is there--do you know if Atsumu-san has a favorite manga?"

"Manga?" Osamu repeats, brows rising.

"Hmm," Akaashi tilts his head. "I think he said something about Jujutsu Kaisen last we talked."

Osamu makes a strangled noise. "Uh, /Keiji/--"

"Ohhhh!" Shouyou lights up. "Jujutsu Kaisen! Awesome, thanks Akaashi-san!"

"You're welcome," Akaashi smiles, returning to his plate of food.

"See ya!" Shouyou calls before dashing back out of the restaurant.

For a moment he thinks he hears Osamu calling to him ("Hey wait, Shouyou-kun!") but when he glances back Osamu's dealing with customers so Shouyou shrugs it off and bikes back to his apartment as quickly as possible.

He spends the rest of the week rewatching the JJK anime

to try and figure out which character Atsumu will dress as for the party--he /really/ wants their costumes to match up, and not just because it would be fun.

He's been /dying/ to ask Atsumu out on a date and he's just certain that this party will be the perfect chance!

What better way to impress Atsumu and show him how compatible they are--how much he cares about his interests--than by wearing a matching costume to the party?

The more episodes he watches, the more /certain/ he is that Atsumu will be dressing as Itadori. It just makes sense!

Itadori's really strong, for sure, and passionate and stubborn. And who else would Atsumu be but the protagonist?! Itadori also dyes his hair and wears an undercut!

Shouyou's convinced he's correctly guessed Atsumu's choice of costume, which means he also knows /exactly/ what

his costume should be. It's so obvious! Who else could be more pivotal to Itadori than /him/?

Shouyou goes to the bathroom mirror and turns his face this way and that, planning his attack and growing more excited by the minute. His grin is /feral/.

This is going to be perfect!

Atsumu's Halloween costume is on fleek. He's styled his blond hair down across his forehead and carefully drawn an elegant swirl at one end of his visible eyebrow. He's got a fake cigarette to hold between his lips and even grew out a hint of goatee.

He feels rakishly sexy.

That could also be from the skintight black jeans that make his ass and thighs even more mouthwatering to behold, especially when paired with the heeled boots he miraculously found in a department store.

A black suit jacket with brass buttons completes the look, and Atsumu is 💯

confident that he'll be able to capture Shouyou's eye--and his interest--the moment he walks into the party.

There are several guests already--Atsumu mingles politely, despite the weird looks Akaashi keeps giving him--while waiting for Shouyou to arrive.

When he does, the plastic cigarette falls right out of Atsumu's mouth.

For weeks Atsumu has been picturing Shouyou swaggering into the party in a green wig and an open shirt, three swords buckled into his belt and a gleam in his eye that dares anyone to challenge him.

But /this/--/this/ is so unexpected, and so much /better/ than anything he imagined that Atsumu's breath goes out in a wheeze.

Shouyou's Sukuna costume is unbearably hot--he's completely bare chested, showing off every lean muscle in his arms and torso which have been accented

with painted-on tattoos forming rings around his wrists and biceps, along with the rest of Sukuna's markings on his chest and shoulders, even his face.

He's /magnificent/, even with extra eyes on Shouyou's cheeks and the smirking curved lines of Sukuna's belly-mouth on his abs.

Atsumu's struck dumb.

Shouyou picks him out of the crowd right away. After a split-second of surprise flitting over his features--mouth an adorable O--Shouyou's gaze turns appraising, his interst piqued.

Ignoring everyone else in the room, he locks on and comes right for him.

Atsumu can only stand there gawping at the double-vision of Shouyou's boyish good looks and fiery hair shining through Sukuna's powerful and chaotic aura.

He swallows, throat suddenly dry. Those rippling muscles head for him with purpose, Shouyou's eyes glinting with mischief.

When he stops in front of him, Atsumu's breath stutters in his chest. Then Shouyou opens his mouth and breaks the spell.

"Atsumu-san! Wow--you look--" Shouyou gestures with his hands, sparkles exploding everywhere as he looks his costume up and down. "You look--/gwaaaaah/!"

Atsumu's stuttering heart chugs back to life and his whole body spreads with warmth.

"Thanks, Shouyou-kun," he replies, shifting into the signature Sanji pose he's been practicing, weight on one foot and hands in his pockets.

"Your Sanji costume is so good!" Shouyou beams. "I didn't know you read One Piece--why didn't you tell me?"

At this Atsumu's expression turns chagrined. "Well..." he scratches the back of his head. "Truth be told I was tryin' to surprise ya."

"Me?" Shouyou points at himself.

Atsumu nods. His palms feel sweaty, but this is no time for nerves--he's determined to confess /tonight/ no matter what.

"Why were you trying to surprise me?" Shouyou asks.

"'Cause ya said ya liked One Piece before, an' Zoro was yer favorite. Thought for sure you'd come dressed

like 'im an' I thought..." Atsumu clears his throat. "Thought it would be fun to dress as a One Piece character too."

Shouyou blinks up at him, eyes wide. "You mean, like matching costumes?" He points back and forth between them. "You and me?"

Atsumu glances to the side, shrugging. Then he squares his shoulders and faces Shouyou despite the heat he feels from his cheeks to his ears. "Well... yeah. Wanted to match with ya. Like we do on the court."

Shouyou presses his lips together, and then pulls his hair. "Arrrghh!!"

Atsumu's jaw drops in shock. For a moment he thinks his plan has backfired in the worst way--but thankfully his fears are short lived.

Shouyou grabs hold of his arms. "Me too!" He exhales, clearly frustrated. "I was going to surprise you too!"

"Me?" Atsumu exclaims.

"Yeah!" Shouyou nods. "That's why I dressed like this!"

"Huh?" Atsumu tilts his head, baffled. He racks his brain--when had they ever talked about JJK before? Had it even come up?

Under the costume makeup, a pink blush spreads across Shouyou's face and neck.

"Well!" he huffs. "When I asked you what your costume would be you said a real strong guy! And then I heard you were into JJK and thought you were going to come here as Itadori!"

"So ya came here as Sukuna, to match with me?" Atsumu gently takes his hands from his pockets.

"Yeah." Shouyou's fingers still grip Atsumu's sleeves, cheeks turning as red as his hair.

Atsumu's chest starts drumming again. "An' why'd ya wanna do that, Shouyou-kun?"

Shouyou swallows. "'Cause I like doing stuff with you, Atsumu-san."

"Me too," Atsumu replies, stepping closer. "I like doin' stuff with ya too Shouyou-kun."

Shouyou smiles, adjusting his grip on Atsumu's arms. "Our costumes may not match, but I think you look /real/ good, Atsumu-san. Epecially the curly brow."

Atsumu can't help laughing softly.

"Yer the best Sukuna I've ever seen," he says, glancing down Shouyou's attractive form. "Nice.../paint/," he squeaks, voice cracking.

Shouyou lifts a brow, and steps even closer. "Just the paint?" he teases, leering at Atsumu.

"/Cheeky/," Atsumu scolds half-heartedly.

Shouyou laughs. "It's okay to look, Atsumu-san. You're the one who inspired my costume in the first place."

Atsumu's whole face whooshes in a steaming flush. "Yer not bein' fair, Shouyou-kun."

"Hm, I think you're the one being unfair," Shouyou counters. "Those jeans? A goatee?"

Atsumu drops his eyes, unable to keep up with Shouyou's words. "W-what are ya sayin'?"

Shouyou's lips curl. "I'm saying I think I better ask you out before anyone else beats me to it."

"Arrghhh!" Atsumu grimaces, cursing.

Shouyou's face falls, letting go of Atsumu immediately.

He rubs the back of his neck. "Sorry, I--"

Atsumu rushes to cut him off, grabbing Shouyou's biceps. "Wait, no--don't take it back, Shouyou-kun, I wanna go out with ya!"

"You do?" Shouyou blinks. "Really?"

Atsumu nods vigorously. "It's just, I was gonna be the one to ask ya!"

"You were?" Shouyou searches his face, a smile pulling at his lips.

"Yeah, promised myself I was gonna ask ya fer a date tonight," Atsumu admits, feeling foolish and giddy all at once. "Guess ya beat me to it."

Shouyou huffs a laugh. "Doesn't really matter, does it?"

Atsumu shakes his head, grinning. "I'll go anywhere with ya, Shouyou-kun. How 'bout we plan somethin' on our next day off?"

"I'd like that," Shouyou replies, a hint of mischief returning to his fond gaze. "In the meantime, maybe we can start by enjoying the party?"

He holds out his hand. Atsumu takes it, twining their fingers. "Sounds perfect to me."

Shouyou squeezes their hands, and they venture off to find some food and drink, never letting go all night.

🦊💞🍊

omake:

Shouyou and Atsumu are inseparable during the party, feeding each other snacks, dancing to the music, sitting on each other's laps and singing every karaoke duet known to man.

It's so cute Osamu ends up kicking them out to the curb--turns out their costumes are so good,

they inadvertently exceed Akaashi's capacity to witness and process such an extreme rarepair crossover such as Sukuna x Sanji and he goes down with a migraine by midnight.

Shouyou and Atsumu feel terrible about Akaashi, but couldn't care less about being kicked out of the party.

Now that they're dating, there are any number of ways they can spend their time and any excuse will do.

Atsumu wakes up covered in Shouyou's body paint and has never felt more attractive--or satisfied--in his life. They spend the morning planning their couple's costumes

for next year.

It's never too soon to start.
