Chapter Text
“So, did I get everything?” Tensei asked him as he began to sort through the pile of supplies. It would have been so much easier if his brother had actually bothered to organize, but if Tenya had expected that level of responsibility from him he wouldn't have felt the need to double check.
“Give me a minute,” Tenya requested.
Swimsuit? Check. Spare Swimsuit? Check. Towels? Four checks. Phone bags? Check and check. Water and cooler? Check and check. Beach ball? Check, three times over. Sand castle supplies? Check for buckets, shovels, and molds. Sunscreen? Check, though time will tell if it will be enough. Tenya doesn't have high confidence in his classmates, yet, to remember to wear any. Medical kit? Check. Tensei’s swimsuit? Check. Tensei's spare swimsuit?
“Tensei?” Iida asked, “I told you to bring two swimsuits! What if you lose yours?!”
His brother rolled his eyes, then pointed down. Tenya glanced down, and saw that he was already wearing a pair of swim trunks.
Tenya huffed, but checked it off the list. He had some concerns about what Tensei will be wearing home, but they had enough towels and his brother was free to embarrass himself all he pleased.
It's not like Tenya could stop him. For as much as he loved his brother, he recognized that the man was, for lack of any less crude language, a chronic dumbass.
“Okay, we can go now,” Tenya said, climbing into the passenger seat.
Tensei laughed, “Even when you're going on a spontaneous beach trip, you're still planning everything out. Isn't this supposed to be relaxing?”
“It is,” Tenya said confidently, “And I have planned it so that everything will go smoothly so that it will stay relaxing.”
Tensei shook his head, smiling. He started the car and began to drive off.
“So,” his brother began, “How did your second day of school go?”
~~~~~~
Katsuki wasn't losing his mind. He was merely understandably concerned about one of his classmates looking way too fucking familiar, and disliking that he can't work out why. That was not losing his mind, and you can't prove anything.
There was something about Moss Hair that was on the tip of his tongue and won't fucking come out. He’s seen that hair before somewhere. Not that long, or in a ponytail like Moss Hair usually wore it, but he knows he's seen that color before. At this rate, he’ll actually have to talk to the guy and confront him about it, which Katsuki won't ever do because that would be admitting defeat.
He wasn't stupid. He knows he can lose. He even knows he probably will lose, likely many times, while training to be a hero. That does not mean he has to like it, or that he has to give up. Katsuki doesn't need to know why Moss Hair looks so familiar, so he doesn't need to ask.
He gets to his house, opens the door, and begins to walk to his room to grab his swimming gear. It's a walk he’s made dozens of times, but this time something caught his eye.
Hanging on the wall, on the walk to his room, were framed photos. Mostly family vacations, with corny labels on the bottom like “He's disappointed that the volcano didn't explode,” or “he’s trying to explode the volcano!” (His first trip to Hawaii was an interesting experience).
One particular photo stood out to him, though. It showed a scowling Katsuki, maybe around three, definitely before his quirk came in. Standing next to him was another boy of a similar age, half a head shorter than the scowling blonde, and smiling brightly for the camera like he was trying to make up for Katsuki’s bad mood.
Now, Katsuki absolutely sucked at recognizing faces. Before his quirk permanently damaged his hearing (and he was still mad at his quirk counselor about that), Katsuki used to differentiate people by their voices. So the star-shaped freckles and round cheeks didn't stand out to Katsuki whatsoever.
What he did notice, now that he was actively trying to remember it, was the kid's hair. It was a deep, mossy green mop that someone dared to attack with a hairbrush and lost.
The label on the picture read “Katsuki and Izu-kun’s first day at school!”
Memories flashed before Katsuki's eyes. The growth spurt, the dumb nicknames, a small voice warning “Kacchan” to wear ear plugs. Katsuki had joked with him that it wouldn't be long before he had to crawl to fit in the building. He had gotten a hollow, awkward laugh in response.
They drifted apart when they were eight. Katsuki didn't know what they were doing the last time they saw each other. They probably didn't know that it would be that.
Except it wasn't the last time. Did Izu-kun know? Or had he forgotten Kacchan just like Katsuki had forgotten him?
~~~~~~
Shouto got into the car silently, taking in the bag of supplies that his sister had grabbed. He had only asked her to get his swimsuit, but she had obtained a bottle of sunscreen, two towels, and a water bottle.
“So, do you want to tell me who else will be there?” His sister, Fuyumi, asked.
Shouto tilted his head, trying to remember.
“It was suggested by Hado Nejire as a celebration for not being removed from the course on our first day. It seemed that she was conspiring with Uraraka Ochaco to do something with Midoriya Izuku, though I haven't determined what their plan was. Yaoyorozu Momo helped facilitate this plan, and they invited everyone on our side of the table. I was sitting between Yaoyorozu Momo and Bakugou Katsuki, and was informed that I was not allowed to miss it.”
Fuyumi gave him a weak smile, “I think they meant that as a joke, but I’m glad that you're making friends.”
“They are not my friends,” Shouto denied. He wasn't sure what the qualities of a friend was, but he knew that he wasn't supposed to need any.
“Then maybe they should be,” Fuyumi said, “Just, give them a chance, please. This is a beach day, not a training session. Try and have fun.”
Shouto stared. He wasn't sure how to do that.
Fuyumi shook her head, “Just ask your classmates when you get there. Do at least, hmm, three beach activities with them. All right?”
“Yes, Fuyumi,” Shouto answered.
The rest of the drive was spent in silence.

Izuku looked at himself in the locker room mirror. Singular, floor to ceiling. Thankfully.
The swim trunks looked… great. Dark green, matching his hair, and going about two thirds of the way down his thigh. That was exactly the problem, nothing looked good on him. Everything Izuku wears looks either stretched out or painted on. He was too bulky for it not to.
This swimsuit, though, it wasn't just lost in his frame. He didn't completely dominate it, and it actually worked well with his musculature. He had not been ready for that.
He tied up his hair, picked up his bag, which now also contained his uniform, and stepped out into the hall.
Yaoyorozu was already there, wearing a deep red, two piece swimsuit. She had a larger bag than before, a full on, black duffle bag that she definitely didn't bring to school with her. She also had two green towels under her arm, which she handed to him.
“My driver came and dropped these off,” She explained, holding up the duffle bag, “The towels are yours. It was nice to practice with such a complex structure. Useful too.”
Then she looked at him, almost in disapproval, “You… nevermind. Let's go outside. I assume that you aren't planning on driving?”
“I can't,” Izuku said, “I have too much mass for it. I can run really fast, though, so I don't really need to.”
Yaoyorozu hummed, walking beside him as he shuffled at a slow pace, “Not even trains?” Izuku shook his head, “Well, let's get some sunscreen on you. I brought a lot, and you’ll definitely need it.”
Izuku winced. He had totally forgotten about that, “I’m not even sure I can be sunburnt,” he admitted. It hadn't come up before, and he was immune to heat stroke, and fire.
“Best not to test it,” Yaoyorozu said, “You don't need to keep pace with me, you know. I know you have longer legs, I can just meet you outside.”
“I know,” Izuku admitted, “I just like the company, I guess?”
It was a lie. Sort of. He did like talking to Yaoyorozu, but mostly he was trying not to be rude. It wasn't too different from shuffling through a crowd.
“Could you carry me out, then?” She suggested, “This bag is kind of heavy, and it would be a useful skill to have for heroics. Especially if you're as fast as you say.”
Izuku hummed, “Oh, yeah, sure,” he knelt down and picked her up, sitting her on his shoulder and allowing her to brace herself on his head. He picked up his pace.
“Not sure I can run like this,” Izuku commented, “You seem unstable up there. I definitely wouldn't want to carry a civilian like this, they'd fall.”
Yaoyorozu hummed, “Maybe I could sit on one of your arms? Like carrying a toddler?”
“Hmm, maybe. Do you think you could switch positions from there? Slide down or something?” He asks, raising his arm into position.
“We're nearly at the door anyway, and the whole point is seeing if you can transport people like that. How about I come with you to the beach? It's in Musutafu, right? That should be a short enough distance for a test like this.”
Izuku nodded, pushing open the exit door with his toe.
~~~
It took longer than it felt like it should have to get sunscreen on. He had enough experience with opening collapsible squeeze tubes and plastic flip caps that getting the sunscreen out wasn't an issue. The problem was that he hasn't had to apply a lotion like this since he could go clothes shopping, and Yaoyorozu kept having to remind him that it wasn't soap and actually did need to be applied and rubbed in fully on every bit of exposed skin, and wouldn't just get there by itself because it was both viscous and completely insoluble in water.
So, after dealing with that, Izuku was more than happy to just lift Yaoyorozu onto his arm, letting her sit securely against his chest, and headed off. He walked out the main gate and immediately leapt over the road and onto the roof of the building on the opposite side of the street. Landing soundlessly, he took off at a jog, so as to not jostle his passenger, and then leapt silently over an alley and landed on the next roof without so much as disturbing the gravel.
Yaoyorozu tilted her head curiously.
“That still feels odd to look at,” She commented, “Why aren't you making any noise, anyway? Do you know? I assume it's for the same reason that you aren't falling through the roof.”
“Yeah,” Izuku answers, “We never, like, confirmed it or anything. We didn't realize that something weird was happening until after I was too big for the exotic energy scanner to work properly, and the nexus scanner couldn't find anything unusual when my Quirk was first documented. My mom's quirk is a kind of telekinesis though, and I am way stronger and more durable than I should be, so we're pretty sure it's some kind of contact telekinetic manipulation.”
“Does that let you swim?” Yaoyorozu asked, “I assume you have some extra density if vehicles can't move you.”
Izuku furrowed his eyebrows, “I don't actually know. Maybe? I mean, I’m pretty sure I can't, like, fly or anything. I haven't really experimented much with that side of my quirk. It’s sort of just… there. I’m not actively using it and it doesn't get in my way.”
“No one questions why something went right,” Yaoyorozu comments, “Negativity bias. You would probably have worked on your telekinesis more if it weren't for your size and strength needing so many work arounds, but since it never caused any problems it wasn't as noteworthy.”
“It still sucks,” Izuku muttered, “I’m a quirk nerd. It really feels like I should know my quirk better than this, but I know the quirks of random heroes from decades ago better than I know my own.”
“I can certainly understand that,” Yaoyorozu tells him, “Creation requires so much work to even use normally that I’ve never been able to push into advanced techniques or get into how it really works. Sometimes it feels like the only way I can progress is learning more complex things to make.”
“It's so versatile you almost don't even need to. It's definitely hero grade already.”
“Maybe,” Yaoyorozu mumbles, “I’m not sure though. It's useful, but it's so slow and hard to use in the moment. How am I supposed to come up with the perfect tool for the job when the villains are right up in my face?”
“Does it need to be perfect?” Izuku asks, “Wouldn’t it be good enough to just be good enough? You don't need a custom solution to everything.”
“Perhaps…” Yaoyorozu trailed off, then the beach came into view, “Oh, we’re here. That was fast.”
Izuku smiled, leaping across the street and landing on the sand, “I can run over one hundred and fifty kilometers an hour, and I don't have to worry about traffic going over the rooftops.”
“Yaoyorozu-kun, Midoriya-kun!” Iida yelled walking over to him, “How was your trip?”
“It was surprisingly smooth,” Yaoyorozu said, as Izuku knelt down to drop her off, “Oh, is that your brother?”
Iida nodded, “He insisted I ask Hado if he could come. Supposedly, we need a responsible adult here, so it was fortunate that Todoroki-kun decided to bring her sister.”
“Hey!” The older Iida said, “I’m an adult!”
“That is not the only qualification.”
Izuku laughed at their antics. This would be fun.
