Yuuei has a support department. A class where students learn how to help the hero's beat the villians. Izuku likes the sound of that. She like tech, and her mum says her mind is hardwired to look at things differently, so Izuku starts learning. Taking apart old broken computers and TV's trying to see how they work. Before putting it all back together of course. She thinks if she can fix something that's broken, then she sure as hell can make something that works.
She moves to things like old furniture and clothing soon. She explains to Katsuki that if she's making things for hero's, than they'll probably need things that they can wear and if she can make a chair, then she can make proper support for the equipment she makes.
Vehicles catch her attention sooner than her mother would have liked, but after a few months Izuku has her own garage where she can work on them. It makes her eyes sparkle and Izuku wonders if she's ever felt this happy or hopeful before in her life. She decides that yes, Katsuki's first smile to her wins that title, but this is a second that Izuku wouldn't give for anything.
