This chapter was not beta-read.
It was one of those not-so rare times when Fuyu's father had to leave for a business trip. The teen would have the apartment to herself for three glorious days.
She had already arranged for Izuku to meet up with her at Dagobah Beach. They had been focusing on different uses for her quirk. Unfortunately, public quirk usage was illegal, so the teens were forced to train down at the beach-turned-junkyard, where they were hidden by the tall piles of garbage.
Fuyu and her best friend only had three more months until the U.A. entrance exam. Although ever since the Sludge Villain Incident, Izuku hadn't done any sparring with the blue-haired teen. She barely saw him outside of school anymore.
Even though they weren't training together, Fuyu noticed the greenette's physical progress. He had grown a good two inches already, almost surpassing the female's 5'6. He was a lot more muscly as well, something which the girls in their class noticed. Fuyu just hoped Izuku never heard what they said in the locker room. The pink-eyed girl thought he would die of embarrassment.
"Hey, Fuyu!" Izuku greeted pulling out the notebook he had dedicated specially to his best friend.
"Hey, Izu. What new ideas do you have for me?"
"So I have several actually, most of which combine some of the techniques you've already mastered.
Last time we checked, you could manipulate the air about 30 degrees warmer or colder. I think we could bring that to about 50 degrees by the time the entrance exam rolls around, providing that you practice with it. If you tried really hard, you could probably go farther, but it would take a greater toll on your body.
"I understand. Quirks aren't all powerful, they're just like a physical extension of our body."
"Exactly. Now, do you think you would be able to control two separate air currents to two very different temperatures?"
The straight-haired teen knew where her friend was going with this.
"Izu...you want me to create a whole-ass hurricane?"
"Well, yes." He replies sheepishly. "You already can create that vortex, which in itself is just swirling air currents moving in one direction. It's applying the theory of that and your temperature manipulation together to change the weather."
"Dude. I'm not All Might. I can't change the fucking weather like that."
"Well not with that attitude you can't! Come on, try it out."
"Izu-"
"What's the worst that could happen?"
"Famous last words. Fine, I'll try. But if I collapse, you better carry me back to the apartment and tuck me into bed."
"Deal."
Fuyu concentrated upon the air around her, imagining it shifting currents. She moved her hands in circles, rotating around each other. Next she focused on the temperature.
Actually, the temperature manipulation idea was given to her by her sixth grade science teacher, not by Izuku. If Fuyu could control the air at a molecular level, she could control the individual atoms to vibrate faster or slower in place, causing a change in thermal energy.
And so, the female did exactly that. She focused on one air current at a time. Once the first current was at a high temperature, she pushed it more to the back of her mind. It allowed her to still control the gust and how hot it was, but also let her focus on the second current.
Just as before, Fuyu manipulated the wind, this time making it cold. Next, she began to bring these air currents together. They swirled together, and both teens felt the powerful breeze emanating from the almost-hurricane.
Suddenly, the wind kicked up even more, and sand flew everywhere, obstructing the best friends' views. Fuyu heard a couple pieces of scrap metal teeter on their mounds, and she quickly cancelled her quirk.
It was a good thing, too, for she soon noticed how much that new technique seemed to have exhausted her. Suddenly, a wave of dizziness slammed into the pink-eyed girl, and she fell to both knees.
"Fuyu! Are you okay?!"
"Y-yeah, Izu. J-Just g-give m-me a m-minute."
Almost five minutes later, Fuyu still felt dizzy and light-headed. Without warning, Izuku hefted her onto his shoulder, fireman style.
"Izu! Put me down! I can walk by myself."
"You obviously cannot. Don't worry, I'll just take you to your apartment. Do you maybe wanna watch a movie together? I can't imagine you wanting to do any more training."
The blue-haired teen smiled softly. "Yeah, that sounds nice. But can you still tell me about the other ideas you have for my quirk?"
"Sure! So basically, in this next technique you'll apply the idea of your gales…"
After a simple dinner of instant ramen, Izuku and Fuyu relaxed on her couch watching a random pre-quirk show, called Avatar or something. It didn't really matter, since they weren't paying attention. Instead they were going over the long list of ideas Izuku had for Fuyu's quirk.
"I can't control water really, much less create a tsunami. My father already tried."
"Well, I just thought that since water is just hydrogen and oxygen atoms, which are both gases, that you could control it."
"Since they are chemically bonded and in a liquid state, I can't control it. Besides, I don't really control 'gases', it's more that I control air as a whole."
"Separate oxygen atoms from water molecules to breath underwater?" Fuyu read off the list.
"Well, it was just a thought."
Taking a marker, Fuyu crossed off anything having to do with water, which admittedly only left her with about three other options.
"Well, now this sounds promising. 'Compress air into itself to create a solid-like form. Use as shield or bartering ram. Similar to force field.'"
"It would again be focusing on the air at a molecular level, similar to what you do with the temperature manipulation."
"It could work. Let's try it out tomorrow."
"Okay! And if you still have energy, maybe we could work on that hurricane thing again. It was really impressive earlier, Fuyu. I could see the wind swirling in front of me, picking up the sand and bits of trash."
"Not exactly the prettiest image there."
Izuku blushed and laughed. "You know what I mean but seriously, Fuyu, you have an amazing quirk. I'm glad I can work on it with you."
"I'm glad you still help me out, even if you yourself don't have a quirk."
Well, I will soon. Izuku thought.
"Fuyu?"
"Yeah, Izu?"
"There's something I need to tell you."
"What is it?"
"Promise me you won't get mad?"
The straight-haired teen narrowed her eyes. "What did you do this time."
"N-Nothing really," The curly-haired boy replied nervously. "Have you ever heard of someone passing on their quirk to someone else?"
"I mean, sometimes children inherit their parents' quirks."
"Well, this is going to be hard to explain. And I can't tell you everything either. The other person involved in this needs complete secrecy.
I met this person who wanted to share their quirk with me. They saw me on the news after the Sludge Incident, and they contacted me."
"So basically they were stalking you?"
"No! Well, not really. See, they told me I could be a hero and that a quirk would help me out. They'd been looking to share their quirk with someone for a while, but they could never find the right person."
"I don't know, Izu. This sounds pretty sketchy."
"Well, they've been training me these last few months. If I'm going to accept their quirk, my body has to be a 'proper vessel.' If not, there's a possibility my limbs could explode."
"YOUR LIMBS COULD WHAT?"
"D-Don't worry, Fuyu. That's only if I don't train properly."
The female scowled. "I don't like the sound of this, Izu."
"Fuyu, I need you to believe me. I trust this person. And...I finally will have a quirk. I'll have the chance to be in equal footing with everyone else. I can be a hero!"
Fuyu sighed. "Izu, you can be a hero without a quirk. But, I can see that this is important to you. I support you, but I want you to tell me if anything slightly suspicious at all happens. I don't totally trust this person, whoever they are, but I'll give them the benefit of the doubt for your sake."
"Thanks, Fuyu. It really does mean a lot." The male had a few tears welling up in his bright green eyes.
"Oh, come on. Don't start crying. You'll make my moody girl self cry with you. Come here, gimme a hug."
After breaking their embrace, the female began to question her best friend.
"Now, what exactly does the quirk do?"
"Sorry, I can't tell you any details about it. It's sorta like a strength, speed and endurance enhancer and a type of stockpiling quirk rolled into one."
"That sounds pretty powerful, Izu."
"It is with training."
"It doesn't matter, you'll always be short and scrawny Izu to me. Seriously though, as long as you're happy with this new quirk, I'll be happy."
"Thank you, Fuyu. I really appreciate your support."
