I-Island.

A place a wonder and mystery! Where the best scientists in the world put their minds to the test of giving heroes that extra edge against the villains of the world. Once a year it would become open to the public allowing those lucky enough to receive an invitation to attend the I-Expo. For heroes and those that aspire to become heroes, the I-Expo would be a valuable resource.

But for a twenty-two year old college graduate with a degree in child development that was aiming to be a teacher next year such a grandiose opportunity meant. Absolutely nothing. She wanted to spend her summer vacation camping in the mountains, maybe brave the beach once or twice, lounge around and wonder how exactly she managed to graduate at such a weird time compared to everyone else.

"Fuyumi," Shoto, her youngest brother pointed behind her. While she did love all of her siblings dearly, Shoto was more than a little odd. Not in the way that one would have expected given how her father had taken to training Shoto daily, but rather because he was blunt. "Your bra is on the ground."

That and he had absolutely no tact.

Wait. Bra?

"Ehh?" Fuyumi let out a whine as she turned to see that her luggage had become undone, and there was a trail of more than just her bra scattered across the terminal. Some of the lighter articles had been blown away by the strong wind and more still were being cleaned up by the trash can like robots that buzzed around the landing strip.

Things were only made worse when a plane decided to take off scattering her clothing even more.

"Ahh! Shoto! Quick, help me collect some of them!"

This was all because their father decided that he was too busy managing his agency to bother going to the I-Expo despite receiving a personal invitation - perks of being the number two pro hero - and decided that it would be good for Shoto to go. And that because Shoto wasn't quite old enough to go to the Island alone, his recent college graduate daughter would be the ideal person to look after him.

It wasn't like she was actually lazing around the house; she was job hunting. It was just summer vacation and schools weren't really in session and it was the middle of the school year, so they weren't really hiring, that normally happened in the fall.

Maybe she should look on the bright side and see this as a chance to bond with Shoto? Or just see this as some kind of awesome vacation on a super advanced resort, they did have a whole week here. Surely there had to be something for her to do at the most advanced place in the world.

With a sigh, Fuyumi looked over the items she had recovered. A bra and panties that didn't match - not that she needed them to match, it just felt good when they did - two striped shirts, her swimsuit top, and a pair of shorts. Fortunately, things like her toothbrush and laptop were easy to recover.

"Sorry, Fuyumi." Shoto muttered, the brisk sea air slapping both of them in the face. He was a bit taller than her now, and something in him had changed recently, it had to be something to do with U.A. he had even started going to see their mother again. "I should have noticed sooner."

"It's alright. Really, it's my fault I should have checked to make sure my bag was closed right." It looked like the zipper had just gotten stuck on something and decided it was time to stop working. The strap inside her luggage really didn't do much to stop her small clothes from falling out.

With another sigh she looked back towards the check in station. There weren't many other passengers on their plane, far fewer than she would have thought, but they were a week early for the event. Why? Because her father wanted Shoto to meet some people there. Joy. "Let's just go check in, I might need to go shopping today."

Might? It was basically a sure thing. She had like two outfits for seven days! There was no way that she was doing laundry five times at their hotel! Wait, what was laundry like on I-Island?

"Alright, do they have shops here?" Shoto asked in that monotone way he had.

"People live here. Of course they have shops." Probably. At the very least they had to have spare clothing!

The line moved quickly.

"Pass please." The security guard from behind the glass window said without so much as looking up from his terminal. Apparently not everything was done robotically.

"Ohh sure thing I, uhh." She reached into her bag and paused. She put the passes with her clothing. On top so she could get them out easily enough. Crap! "Uhh, we had a bit of an accident on the tarmac and my luggage kind of went flying. And our passes kinda got blown away."

She gave her best smile.

The security guard gave a sigh and gave her the most judgemental eyebrow raise she had gotten in years. "Names please."

Oh thank fuck she thought they were going to say no pass no entry or something like that. "Fuyumi Todoroki, and Shoto Todoroki. Uhh, if it helps our dad is Endeavour? We're here on his-"

"You're a month early." The security guard flatly.

"Excuse me?" She squeaked, feeling her stomach drop. "A month? Isn't the expo supposed to happen June Seventh?"

"No, July Sixth." The security guard said planely.

"So we can't get in for a month?" She all but shreaked, she could feel her hair going grey. Wait, her hair was mostly white already. Could she get grey hair? "What are we supposed to do?"

"I can make us a boat and we can sail back to Japan." Shoto offered.

She wasn't sure if he was serious or not. He'd been saying weird things ever since he went to U.A. Maybe he was developing a sense of humor?

The security guard let out a sigh. "Most people don't fuck up this bad. I get that we use the American date system, but we've always had the I-Expo in July."

She didn't know that! This had to be some kind of a twisted prank! It did explain why no one saw them off though. Stupid stupid stupid! How could she mess up so badly. Oh right, she just ordered the tickets with her phone and went back to eating chips and pretending her family was normal and happy!

"How about we say they're with me!" The raspy voice of hope came from a girl with long wild green hair that was tied in a ponytail that really didn't contain it. She had a freckled face and a bandage on her nose. Her button up shirt was tied around her waist, exposing the black tank top she was wearing, a pair of dark green socks went so far up her legs that they almost met her shorts.

She looked kind of familiar.

"Izumi?" Shoto asked eyes going wide and the faintest hint of a smile appearing on his lips. Shoto knew her? "What are you doing here?"

"I'm here to stay with my big brother for the summer! He's a researcher here on the Island!" The girl wrapped her hands behind her back, leaning forward and smiling at Shoto. "Apparently, he's a big shot too! And I have two extra passes with me. One was supposed to my mom, but she decided to spend time with dad instead. And the other was for Mei, but I think she got arrested for trying to bring an explosive onto the plane."

"Ahh. The girl from the support class?" Shoto asked. Was he actually engaging in conversation with this girl? And he was making direct eye contact? Well he normally did that. But this wasn't his normal eye contact this was something else.

This was perfect! Her little brother had a friend! She needed to do the big sister thing and - wait, why was Izumi taller than her? It wasn't by more than an inch or two. Dammit, why was she so short? "Shoto, could you introduce me to your friend?"

"Oh. Fuyumi, this is Izumi, she's my classmate from U.A." Shoto gestured between them.

"Nice to meet you." Izumi gave a polite bow.

"And Izumi, this is my older sister Fuyumi, she's trying to get a job as a teacher." Shoto continued.

"Nice to meet you as well, Izumi," Fuyumi extended her hand to the girl. "I trust you've been keeping Shoto out of trouble?"

Izumi took her hand and laughed. "Hehe, nope, I get him in trouble when he comes to get me out of trouble. But let me get checked in. I can't wait for you two to meet my brother. Oh. And how old are you Fuyumi?"

"Twenty two?, why?" She let Izumi past and watched as the girl got checked in at the station with a shocking amount of ease.

"I knew it! That's about how old my brother is! He turns twenty three next month." Izumi took the three passes the security guard gave her and presented one to Shoto and Fuyumi. "Oh! I bet you two would get along great! I have a good feeling about this kind of thing. Like how I knew Shoto would be an awesome partner once I got rid of his cold shoulder."

"Only one of my shoulders is cold." Shoto said, missing about twenty signals.

Izumi blinked at him before snorting. "Come on, Come on! Let's go!"

Fuyumi watched as this bubbly energetic girl grab onto her brother's arm and pull him a long. Part of her wanted to respect Shoto's privacy and just let him be. But a much larger part of her was squealing in delight and wanted to know everything about what Shoto thought of Izumi. Did he like her? Did he like like her? How close were they? How did they meet? Did Izumi like him? Could she like him? Really this was the first time she had ever met a friend of Shoto. This was so exciting!

Wait. Was there something wrong with Izumi?

No, she shouldn't be so cynical She should just be happy that her littlest brother was friends with anybody. The fact that it was with a cute girl was just a bonus. And then there was the look on Shoto's face. There had to be something there.

And apparently she had over a month to find out.

Wow, was she really the type of sister to meddle in her brother's love life?

Yes, yes she was.

XXXX

"Hey, Shoto," Izumi tugged on his arm and whispered into his ear. Her hot breath caused his spine to tingle in the middle of his back and made the hairs on the back of his neck stand up. "Can I ask you a question?"

"You just did."

He shouldn't have said that.

Izumi did that thing she did whenever ever he said something weird. It was something of a glare mixed with a pout and she let go of his arm. "I meant another one."

"Oh, okay."

"Is your sister seeing anyone right now?" Izumi asked her eyebrow raised and one hand was on her hip as she looked him in the eye. "Like romantically. Does she have a boyfriend."

He looked back towards Fuyumi. He really didn't know. But he did hear Natsuo saying she'd never get a boyfriend if she didn't leave the house. "I don't think so."

"Great," Izumi flashed him a wide smile and moved in close again. "I want you to help me get her and my brother together."

"Why?"

She rolled her eyes. "Because, they'd be cute together, she's totally my brother's type. I think. Besides he's hopeless when it comes to romance. So what do you say. Want to help me?"

Shoto looked back towards his sister as she called Natsou to tell him what happened. She probably just texted father. Fuyumi. "Would your brother make her happy?"

"Yep! And then when they get married we'll all be one big happy family." Izumi let out an ear to ear grin and rubbed a finger over her bandaged nose.

Family. That was what Fuyumi wanted, wasn't it? "Okay. I'll help."

AN: I want to write more Fuyumi.
