Izumi's Birthday Bash

Summary:

Izumi didn't both to let anyone know that today was her birthday. Izumi isn't very good at keeping secrets. Izumi is about to be cherished.

Work Text:

Izumi’s birthday had been fairly low key. She called her mother and spoke to her for about an hour, she texted her father in America, she visited her favorite restaurant and spoiled herself with some katsudon, then she just spent the rest of the day training like normal. If she felt like it, she might get some ice cream before bed, but otherwise, she was content to just keep practicing Shoot Style. Her birthday wasn’t that special anyway.

“HEY! DEKU!”

Izumi looked up to see Ochako’s (ridiculously) pretty face sticking out of the window of 1A’s dorms.

“Oh! Hey babe! What’s up?”

“All the rest of the girls are having a girls night right now, we were wondering where you were.”

“Oh I’m just down here getting some extra drills in, I hope you guys are having a nice time!”

“We’d be having an even better time if you came up here! C’mon!”

Izumi’s whole body went limp. “They want me to hang out with you guys?”

“Why the fuck wouldn’t we want to hang out with you? You’re awesome!”

Izumi resisted the urge to start crying.

“Okay, I’ll be right up!” She whimpered, tears streaming down her face.

Her resistance was ineffective.

Ochako giggled. “See you inside, Deku!”


 

Izumi took a deep breath as she walked back into the common area. She was never sure where to sit. On top of her own horrific history of being excluded and being bullied that left her feeling completely unsure of herself in every social situation, she also wasn’t entirely sure where to place herself given that she now took a whole lot more space than she used to.

It had been about 18 months since she’d first met All Might during her last year at Aldera and she’d grown taller and more massive in the last year and a half. She’d sprouted from 1.6 meters and maybe 52 kilos to 2.1 meters and 130 kilos of raw power. She’d really liked the changes but it had, perhaps paradoxically, made her even less sure of herself. She wasn’t sure whether it was okay for her to take up space or whether she should stick to making herself small. She was obviously stuck in her own head but-

“Hey! Izumi! We saved you a seat!” Called Asu- Tsu. Called Tsu.

Izumi chuckled and took a seat on the couch between her beautiful girlfriend and the frog girl. Tsu had a great way of grounding people for some reason. Maybe it was because she was the only big sister of the bunch, where all the rest of the 1A girls were only children or younger sisters.

“So what’s going on?” Izumi asked.

“Well Kyoka was talking about her favorite pre quirk bands and she asked us all what ours were,” Yaomomo explained.

“I said it was Green Day for the record,” Jiro explained.

“Not surprising,” Izumi nodded. “What did everyone else say?”

“I said Foo Fighters,” Ochako answered.

“The space girl loves the band named for UFO hunters?” Izumi teased.

“Hey at least I didn’t pick the band that was literally called UFO,” her girlfriend retorted, a wry smirk on her face.

“Fair point,” Izumi chuckled. “How about everyone else?”

“The Mountain Goats,” Tsu replied.

“The Jonas Brothers,” Hagakure and Ashdio giggled.

“Nightwish,” Yaomomo supplied.

“Really?” Izumi asked.

“Really,” she answered, a small smug grin on the heiress’s face.

“So how about you Deku?” Ochako asked.

Izumi sat back and thought. That was a good question.

“I’d have to think about that, I don’t listen to that much pre quirk era music.”

“What do you usually listen to when you work out?” Jiro suggested.

“Audiobooks usually. Mostly about the history of pro heroes and vigilantism.”

Jiro looked at her in shock and a bit of confusion.

Ashido snickered. “I’m sorry, but I’m just imagining you grunting with effort while some poised narrator is explaining about the history of the Crueller.”

“The Crawler,” Izumi corrected, giggling.

Ahsido smirked and moved towards the edge of the couch, putting one hand on her knee while balling her opposite hand into a fist. “So you’re just like, ‘Ugh. 46,’” she grunted, while pantomiming lifting a dumbbell. “‘Ugh. 47,’” she grunted again. “‘Ugh. 48.’”

“In 2246,” Hagakure added, in a very posh, news announcer voice as her best friend kept grunting out numbers. “The individuals known as Knuckleduster, The Crawler, and Pop Step first began making frequent public appearances together, becoming known as the Naruhata Vigilantes.”

The five remaining girls all cracked up, with Izumi trying not to barrel over. “You joke, but that’s pretty much exactly what it’s like.”

“Okay, okay, jokes aside, what do you listen to when you just want to run around town and want something that really makes you feel like you’re free and that you can do anything at all?” Jiro asked.

Izumi thought some more then nodded. “I guess I’ll say Weezer, I’ve always liked that first album of theirs.”

“Oh blue is a great album!” Jiro agreed, sounding just a little bit relieved.

“My Name Is Jonas is a great opener, every time I go for a run using my quirk just for practice, I put that song on and I immediately feel like I could run through a brick wall.”

“You probably could!” Hagakure teased.

“Well not without breaking my face,” Izumi laughed.

“Well we don’t want that,” Yaomomo giggled.

“Especially not Ochako,” Tsu teased.

“Shut up,” Ochako grumbled, her face turning red. Izumi’s face turned red too.

The other five girls laughed.

Their laughter quickly turned into awws as the two of them began to hold hands even as they were blushing like a tomato.

“Speaking of practice though,” Yaomomo noted, trying to change the subject to avoid embarrassing the couple more. “Why were you just drilling outside on your own?”

Izumi shrugged. “I didn’t want to accidentally break anything.”

“But why were you on your own? I’m sure Kirishima would love to be your practice dummy.”

“Knowing the way he stares at those guns of yours, I think he’d love to be your dummy period,” Ashido quipped.

Izumi looked at the pink girl puzzled. “Are you saying that-?”

“Eijiro likes you? No, he loves you. He’s been in love with you ever since he saw your glorious muscles walk out of the locker room on the first day. We’ve literally agreed you’re his hall pass.”

Izumi’s face soon had her looking like Ashido’s long lost sister. “Hall pass?”

“Oh yeah, a hall pass is basically when your partner lets you fuck someone else behind their back and it’s okay as long as it’s this one single person.”

The others stared at her blankly.

“Okay, so none of you have a free pass?” Ashdio pouted.

Hagakure groaned. “I’ve always kind of wondered what it would be like to get down. Kuroiro. The girl who manipulates light and the guy who manipulates darkness. It could be interesting.”

“You want to sleep with him just to see how your quirks interact?” Izumi asked.

“What? You don’t approve?” Hagakure replied.

“Not at all, I kind of want to get my notebook out,” the tall girl giggled.

“Okay, let’s get off that subject and back on the subject of you drilling outside by yourself, why didn’t you ask anyone to spar with you? I’m sure Bakugo at least would love to square up with you,” Ochako noted, trying to get back on the original topic.

“Or Iida,” Yaomomo suggested.

“Or Kendo from Class B,” Jiro offered.

Izumi shifted uncomfortably in her seat. “Well… To be honest, I didn’t think anybody would want to spend any time with me.”

The other six girls all immediately sat up, an intense look on their faces. Izumi groaned. She already regretted this.

“Midoriya, you are loved by all in this school, especially by us and our male classmates,” Yaomomo reassured, putting a hand on Izumi’s shoulder.

Izumi groaned again. “I know, I know, it’s just…”

“People gave you a hard time before you got to UA, we know,” Ochako said softly, smiling fondly as she gently squeezed her girlfriend’s hand.

Izumi nodded. “I’m sorry, I shouldn’t close myself off like that, it’s just that I’m so used to being told no that I never ask anymore because I know that I won’t get a yes, even if I know the person I want to ask already would probably say yes, I just assume they’ll say no.”

“Just let one of us know next time you want to do something, we’ll either say yes or we’ll point you to someone who will,” Yaomomo suggested.

“Why don’t we get together for your birthday?” Ashido suggested.

Izumi shifted nervously “Yeah… About that…”

The pink girl’s shoulders slumped. “You didn’t!”

Izumi didn’t respond.

“YOU FUCKING DID!”

“What? What’s going on?” Hagakure asked.

“Her fucking birthday was today and she didn’t tell anyone!”

“WHAT THE FUCK?!!?” Hagakure screamed.

“Deku!”

Yaomomo groaned. “Jiro?”

“Yeah Momo?”

“Could you please be a dear and get the rest of our class, we need to hold a birthday celebration for Midoriya.”

“You got it!”

“Oh you guys, that’s really not-”

It was too late, Jiro was already off the couch and running down the boys hallway, knocking on doors.

“C’mon guys, it’s late, let everyone sleep in and we’ll do it over tomorrow.”

“I KNEW THAT WAS FUCKING TODAY!”

Izumi groaned. It was past the point of no return now.

Aizawa-Sensei walked in, visibly groggy and more than a little annoyed. “Why is Bakugo screaming?”

“Jiro just told him that Midoriya didn’t tell anyone it was her birthday,” Ashdio answered.

Aizawa let out a heavy sigh and nodded. “I’ll call the other teachers and see if any of their students want to stop by.”

“Listen, guys, I appreciate this but am I really worth all this attention? It’s getting late!”

“It’s only 8:15, Deku. Now someone go grab that diabetic hulk douche and help me get a cake together.”

“Kacchan, what do you mean ‘only’? You’e gone to bed at eight on the dot every night since we were 5.”

“Shut the fuck up and let us treasure you, Izumi!”

She blinked. She hadn’t heard him call that since they were 3.

“Midoriya.”

Izumi turned to see Shoto Todoroki looking up at her, a little bit hurt. “Yeah Todoroki?”

“I’m a little bit hurt you didn’t mention that it was your birthday to me, I would’ve gladly spent the day with you.”

“Well, you were already going to spend the day with your brother and sister, and I didn’t want to get in the way of that.”

“They would’ve enjoyed spending the day with you as well, you made a very good impression on them during our dinner together during our internships with my dad.”

Izumi nodded. “Well give Fuyumi and Natsuo my love.”

“They’re actually coming here to give yours.”

Izumi’s whole body went slack. “You’re kidding.”

The door bell to their dorm rang.

“I’ll get it,” Aizawa reassured.

At the door was Hatsume, Shinso, and the big three, along with Kendo, Tetsutetsu, Tsunotori, Kodai, Tokage, Komori, Yanagi, Awase, and-

“Monoma? What are you doing here?”

“Surprised to see that the superior Class B is down here slumming it with you 1A scum?!”

“I’m not surprised people from Class 1B are here, I’m very surprised that you specifically are here.”

“Well, let’s just say when I meet someone who appreciates quirks as much as I do, you learn to appreciate that someone just as much even if they are a rival.”

Izumi blinked. “You see me as a rival?”

“Not you specifically, your whole class is my rival.”

Izumi nodded. “Fair point. Well come on in you guys!”

“Hey there twin!” Mirio chirped, grinning from ear to ear.

“Hey twin!” Izumi chuckled, smiling at the blonde she shared a birthday with.

Mirio high fived her. “I can’t believe you didn’t say anything sooner.”

“Given the fact that the last time we hung out, just you and me, we bumped into a little girl that was being tortured by the mob, I’m not sure us sharing our birthday together would end with either of us having a good time.”

Miro laughed. “Good point. Next time bring your girlfriend and I’ll bring mine.”

“Girlfriend?”

Amajiki lightly waved his hand.

“Oh! Okay!”

Ochako wrapped herself around Izumi’s arm, nuzzling against her skin..

Izumi shook her head. “I don’t know if I’ll ever be able to get used to this kind of thing.”

“Being loved by all of your friends?” The brown haired girl teased.

“Well… Yeah.”

Ochako giggled. “Get loved bitch,” she stood up on her tiptoes and kissed her girlfriend’s cheek. “Get absolutely treasured.”

Izumi smiled at her. “Thank you for this, Ochako.”

She grinned up at the tall green haired girl. “Happy birthday Izumi.”
