"Happy birthday Izu-bro!"

"Happy birthday Mirio!"

"Wow, wow wow! What are the odds you two would have birthdays on the same day in the same month!" Nejire said floating around the two best friends. "You two really are like brothers!"

Tamaki nodded his head in agreement with a small smile in his face, remembering when he first found out about this.

"So, what are you doing for your birthday Mirio?" Tamaki asked.

Mirio tapped his chin, thinking of what he could do for this special day. Before he would have a simple family dinner but now, he had Izuku with him so he should do something with him.

"Well Tamaki now that I have Izuku under my wing I think I should do something special for my little friend, would you like to join us?"

"Oh, has Izuku never been invited to a birthday party or something?" the boy asked.

"AAHAHAHAHA, silly Tamaki, well yes, but also no. Izuku and my birthday are the same day, we're like twins except we're not, you know!"

"So basically, two people with the same birthday?" Tamaki specified.

"Yeah, two bros with the same birthday!"

Tamaki wanted to tell Mirio that just because you share a birthday with someone doesn't mean you are technically related but Mirio looks so happy to be sharing a birthday with Izuku.

"Amazing Mirio, you're like twins, but not" he chuckled.

"RIGHT! Now come on let's go find my Izu-bro so we can celebrate our birthday's together!" Mirio yelled not realizing he had sunk through the sidewalk causing Tamaki to have to run and catch up to the boy with his clothes.

"I know right. It makes celebrating our birthdays together so much easier!" Mirio yelled pumping his fist, Izuku nodding his head copying Mirio.

"Yeah, Mirio and I have been celebrating together since we first met and found out our birthdays were at the same time!" Izuku grinned.

Nejire and Tamaki had to close their eyes at the huge smiles the two boys were giving them, the light shining over them slightly blinding the duo.

"Too pure" they thought.

"So, what do you two usually do, Nejire asked, being the newest member of their trio.

"We're glad you asked Nejire" Mirio said, "we do a lot of stuff."

"Ranging from the arcade- "

"To going to Tokyo to visit the museum of All Might!"

"Don't forget touring the Heroes Hall of Fame!"

"Oooh, that sounds like fun! What do you plan on doing today!" Nejire asked jumping around.

Mirio scratched the back of his head, Izuku mimicking him, as they both looked at each other.

"We were planning on visiting the Museum of All Might again."

Tamaki didn't even try to hide his chuckles having expected that. "Of course, you did."

"Happy birthday Izu-bro!"

"Happy Birthday Miri-bro!"

"They really enjoy having the same birthday don't they", Nejire giggled.

"Of course," Tamaki said sheepishly, looking at the two boys wrestling, the younger of the two losing miserably.

"I'm a little confused as to who we're dressing up as?" Nejire asked as she looked at Tamaki in a red costume with a lighting bolt on it, Mirio in an orange and green ensemble with a weird trident, and Izuku with a blue and red suit with a S on the chest.

"Excellent question Nejire and we are glad you asked!" Miro shouted, "Izuku if you would."

"Well it's interesting really because before the quirk era there was the pre-quirk era as you know"" Izuku began explaining.

Nejire nodded her head listening intently. "yeah, yeah, yeah I think I remember hearing something about that but what of it?"

"Well it's interesting because as it turns out most of those heroes were either not born from earth-

"I.e. Superman" Mirio says, pointing to Izuku who posed with his arms akimbo.

"Was caused by some sort of experiment gone wrong" Izuku said pointing to Tamaki.

"The flash" Tamaki muttered, assuming a running position.

"Was part of an underwater civilization" Izuku continued.

"Aquaman" Mirio announced dramatically pounding his trident down.

"Or was created by the gods themselves! Wonder Woman!" Izuku yelled to Nejire who was wearing an exact replica of Wonder woman's suit.

"Oookay. But that still doesn't explain why we're dressed as them? Or why there's a photographer over there? Or why these costumes feel so authentic?"

Mirio and Izuku at least had the decency to blush, while Tamaki thankfully was nice enough to hold back his laughter already having dealt with their eccentrics.

"Oh, well you see" Izuku looked away unable to really explain their reasoning, left it to Mirio to tell Nejire.

"We just like to take pictures as these superheroes from time to time" Mirio said a bit embarrassed.

"Yeah, we thought you'd like to join us, since we finally found someone to be our Wonder Woman" Izuku mumbled, kicking his foot back and forth.

Nejire felt a sharp pain in her chest at the adorableness of these two hit her. They're too much for me, she thought.

"Awwwww, of course I'll be your Wonder Woman, my little Izu-kun! But that doesn't explain the authenticity of these outfits?"

"That'd be Tamaki he's very good at sewing" Mirio said smiling at his friend.

"Oh, yeah he did our costumes last year too!" Izuku said happily.

"Aww, you and Izuku hang these pictures up in your room, Nejire cooed.

"Of course, where else would they go?" Mirio asked looking at his friend confused.

"Well actually mine go in my wallet, I rather not someone see these at the orphanage as much as I love dressing up with Mirio" Izuku says, showing all the pictures they've taken of them dressing up.

"My parents hang up the ones I take with Mirio and Izuku in the living room" Tamaki grimaced, Mirio and Izuku laughing at the boy's misfortune.

Nejire nodded her head in understanding as she looked through the pictures Izuku had in his wallet stopping at one in particular that had caught her eye.

"Wait a sec, did you and Mirio really dress up as All Might and Endeavor!"" Nejire said trying to hold back her giggles but failing.

Izuku merely nodded, while Mirio smiled pulling out his framed version of the two.

"Izuku wanted to be All Might but seeing as his quirk is pyrokinesis and he can actually set his face on fire we figured he'd have to make the sacrifice." Mirio said apologetic to the sulking boy.

"I still think you could've been Endeavor" Izuku muttered.

"Really Izuku, really. And miss out on a mini Endeavor" Mirio points out looking to the picture with a green haired boy glaring while sporting a green fire mustache and flaming hair.

"No, no I gotta agree with Mirio here you look adorable my little Izuku, you even got his glare right and Mirio wow, how did you get your hair like that?" Nejire asked, pointing to the V shaped hair style.

"Mirio's hair used to be longer in middle school" Izuku answered remembering when Mirio used to wear ponytails.

"Yup, but eventually I cut it unlike this bushy haired kid" Mirio says smiling.

"Well I mean I could always-

"Don't even think about it" Nejire says grabbing a handful of the younger boys' curly hair, that she was just running her hand through.

"I mean , whaaat I would never want to cut my hair nope no siree, why would you even suggest something like that Mirio you monster!" Izuku yells, breathing when Nejire lets go and goes back to running her hand through his hair.

"One day" Izuku thought, only to feel another tug and the older girl glare at him as though she could read his mind. "Okay, maybe not."

I figured I could do chapter about their birthdays being on the same day and since they already did a photoshoot for the wild wild pussycats is it really so far fetched that they wouldn't dress up as superheroes from pre-quirk eras and bring in Tamaki and Nejire into. Hope you like this. Also if you read the comments Nejire is the majority for the relationship so yeah, sorry for all you Itsuka shippers hope you don't abandon me for for that.

And if you like my stuff help a starving writer and hit up my ko-fi or not but I'd definitely appreciate it. i'm under the same username
