"MERRY CHRISTMAS!"
Izuku jumped a mile in his skin at the sudden declaration, looking up into the dormitory to see a sight that made his jaw drop. Overnight, the mostly barren 1-A dormitory had been transformed from only having a tree to now being laid over with a bunch of white carpet imitating snow, mistletoe and wreaths and over such plants all strewn about in tasteful ways (with all the mistletoes kept away from where one could accidentally stand under them, likely at Iida's insistence), and there were flashing lights all around, illuminating the room, although none were as bright as the Christmas tree.
Speaking of, Kodai from 1-B had clearly been brought in to help, as it now stood a good nearly twenty-foot-tall, scraping the roof. Then there was Iida, bustling about while dressed up as Santa Claus on a diet, being followed by Kaminari, Kirishima and Sero who were dressed as elves. Todoroki walked in front of them the whole time with a massive red nose stuck on his face and a bemused expression.
The real jaw dropping sight for Izuku though was the girls (and not in a pervy way like Mineta would find it, although based on a glance some of the girls were aiming for that), for they had not opted to dress up as typical Christmas characters.
They'd opted to dress up in festive versions of hero costumes both real and fictional. Ochaco noticed him and waved him over with a massive smile, kitted out in a Scarlet Witch costume, but with green leggings, a wreath necklace and reindeer ears atop her hairband. The coat was also a brighter red than normal. "Hiya Deku!"
"Glad to see you here. Ribbit." Tsuyu croaked from beside her, wearing a costume based on Ragdoll, except the white parts of the outfits were now red and the yellow parts were now green. Izuku could only tell it was Ragdoll specifically because Tsuyu had done her hair up to be like the currently inactive hero's hair. She had a little bow designed to look like a Christmas tree in her hair and she gave him one of her cute massive frog smiles.
"Mm." Kodai nodded in greeting, making Izuku jump as well as go bright red the second he saw her costume, a red sling swimsuit clearly based on Vampirella but with a green hood and green jewellery. Izuku quickly hid his face and turned away.
"K-Kodai?!"
"Mm?"
"Don't bother, Deku." Ochaco said with a sigh, looking embarrassed herself with a red tinged face. "She's insisted she has to wear this if she's going to spend her Christmas here."
"A-And why are you a-all here? I m-mean I'm h-happy to see you b-but I thought you'd all be gone…" Izuku frowned. Everyone else but Todoroki had gone home, leaving just him and the two-tone haired teen alone. Izuku would have gone home, but his mother had to go into her work so there would be no point and everyone else had been allowed to go home during the holidays.
"We were for a bit. Ribbit. Then…. Well, Kyoka overheard you muttering to yourself when she was leaving." Tsuyu explained with a sad croak.
"O-Overheard?" Izuku asked confused, and a new voice behind him got him to whirl around.
"I didn't mean to dude, but I heard you mention this was the first Christmas you'd have you'd be happy during…" Kyoka had appeared, frowning sadly.
Izuku took one look at her costume and felt his heart jump (as well as something in his pants, though he'd never admit it in a million years), as she was wearing a tight black jumpsuit based off of Black Widow's, with a red utility belt around the middle and several bits of green jewellery. You wouldn't expect it based on her own hero costume, but Kyoka most definitely had the curves to be at risk of tearing her costume open and Izuku really hoped he hadn't stared too long.
Kyoka was just smiling gently. "So I called the other girls, cause no way was I just leaving you after that. They all started planning and Ochaco got called Iida and Todoroki to get some of the guys and well, here we are."
"A-And what's w-with the hero costumes?" He asked curiously.
"You noticed?" An amused voice brought their attention around to another group of three approaching.
Mina, Kendou and Tokage, the latter of whom was smirking, wearing a leotard based off of She-Hulk's presumably but with Christmas décor painted on the white middle section all the way up. It was also very, very thinly cut, barely covering her shame and more than likely shared a similar problem at the back, making Izuku go redder than Rudolph's nose. "You staring at our assets, Midoriya?"
"W-WHAT?! NO!"
"Setsuna, be nice." Kendou warned her classmate with a shake of her head. She was wearing a much more normal outfit, based on an old comic series and a character within, Mangaverse Mary Jane Watson, with red leggings and a red tank top that had a massive green spider emblazoned on the chest, as well as glasses with green frames that gave her eyes the appearance of giant Spider-Man style eyes. "Ignore her, Midoriya. She just loves messing with people."
"He's cute when he blushes though!" Mina giggled.
She was the third of the new arrivals, decked out in a black bra and panties, which had little mistletoes hanging off them and Izuku looking literally anywhere else. The only thing that gave away what her costume was meant to be was the black stripes she'd painted on her body, indicating she was dressed up (or rather down) as Tigra.
"As for why, Midori, we just know you like heroes so we thought it would be a nice way to make sure it's a great Christmas for you. Just think of it as a Christmas present!"
"TOKAGE! ASHIDO! THOSE OUTFITS ARE NOT APPROPRIATE!" Iida stormed over, waving his hands wildly all the while. "YOU CANNOT-"
Smack!
"Ow! Iida, careful!" Tooru's voice came from nowhere. Suddenly, a blue Fantastic Four suit faded into existence, with green and red trimmings all over it.
"Hagakure?!" Everyone seemed surprised, blinking at the suit. "How'd you do that?"
"Oh, Mei made me a suit finally to go into hero training with. It responds to my quirk and lets me alter the light it takes in so I can make it look however I want including invisible, so now I don't have to be buck naked." She said, a grin evident in her voice. "That's not what we're here for today though. And if Iida's complaining about you two's costume, I can't wait to see his reaction to Momo's when Reiko brings her in."
Mina narrowed her eyes. "Tooru… Did you corrupt Momo without me?!"
"Nope! The internet just lied to her about her costume and Reiko's trying to coax her in-" As if on cue, the door opened and in walked Reiko first, dressed up as Silver Sable with a Mistletoe headband in her hair, her bust and rear far more pronounced then it seemed anyone was expecting as Izuku noticed he wasn't the only one whose face lit up red. It only got worse when Momo walked in however.
She had clearly tried to come dressed as Ryukyu, with green replacing all the non-red parts of the costume but the outfit was… well… the collar opened up into a very exposing boob window, showing off a very immodest amount of cleavage, only barely stopping before things became too revealing to be allowed, the cloth stopped just on top of her crotch exposing her panties beneath which were clearly decorated with painted Christmas trees and baubles and when she turned, not only did they all get far more of a view of her body then any of them ever expected to get, but the back was very open, exposing a lot of her skin and only closing up right above her rear.
Iida looked like he was going to have an aneurism.
"C-Can we j-just get onto the p-present openings so no o-one stares at me a-and this h-horrible costume?" Momo whined and they all nodded.
"Sure, but for the record you look great!" Mina assured, before grinning mischievously. "Right, Izuku?"
"W-What- Ow!" He got an elbow in the side. "I m-mean, y-yeah, c-completely stunning!"
Momo's face lit up a bit at that, making her go from being unfairly attractive to unfairly cute in an instant. Still, Izuku hadn't lied, she really did look stunning. Then again, it was Momo, she always did.
"Well, let's start with my present to Izuku please!" Setsuna immediately rushed to the tree and pulled one out and Izuku failed to notice a lot of the girls grinning and giggling as Setsuna brought her gift over and shoved it into Izuku's hands. Confused, he opened it up only to find it had a hole in the bottom and…
"Mistletoe?"
Suddenly, Setsuna's detached lips shot out from the hole in the box and landed on his, making him go wide eyed as everyone else giggled.
"Got ya!" Setsuna grinned, throwing an arm around his neck. "None of my friends escape these lips on Christmas, you'll learn that now!"
Izuku just sat frozen until eventually, he nervously joined in the giggles with the others, admitting she'd gotten him good. From then on they ate, talked, played games and laughed all the while as Izuku's heart soared high thinking about the fact they'd done this all for him.
However, he couldn't help but notice many of the girls sneaking glances above him and either going red faced and stuttering or laughing and grinning. He didn't find out why until the end of the day.
"Well dude, before we leave, it's time for one last gift." Kyoka smiled shyly, pointing above him. Confused he looked up and went wide eyed as he realized someone had snuck a mistletoe into his hair without him realizing and the next thing he knew he suddenly felt a pair of lips quickly peck him, looking down to see a bright red Kyoka smiling nervously at him. "Setsuna sneaked it onto you with her present, enjoy."
She backed away and before Izuku could ask what she meant he felt fingers on his shoulder, getting him to turn only to find an eager Tooru kissing him, followed by Mina, then Yui, then Kendou, followed by Ochaco and Tsuyu. After that came Reiko and finally a very shy Momo.
Izuku was just stood frozen at the end as Momo nervously pulled away. "Well uh… H-Happy Christmas- I mean Merry!"
And with that, they all started to depart, most of the girls either giggling wildly or blushing furiously, while the rest of the guys stared at Izuku equally as shocked as he was.
Then, despite himself, a very small smile made its way onto Izuku's face as he collapsed into a couch.
A Happy Christmas indeed!
