This is a story about a girl from the Support Course and a boy from the Hero Course. They first meet at the opening ceremony for those who applied at U.A. :>

"This is kinda boring, and the guy giving the speech is loud. Makes sense though, he is the Voice Hero" the girl mumbles to herself

A student with blue hair stands up to make a statement about the physical exam robots. Once he's finished talking about that he points to a boy with green hair and calls him out on his consistent muttering. He finally finishes talking and sits back down. Finally everyone is released to go to there respective battle zones. That is where i see a boy with white and red hair, he gives off a cold yet warm aura. I wonder what kind of quirk he has?
