Aizawa found you in a small room after he captured your villain parent, who had neglected you for years. You were taken in by authorities for questioning, and after you were not deemed as a threat, Aizawa decided to adopt you. It's been almost 4 years since then, and you're now a student at U.A. in his class, at 16 years old.
A lot has gone on while you attended U.A., and you honestly have enjoyed your experience, despite how difficult it's been at times. You've gotten stronger, and your quirk only proves it. You couldn't have been happier to be able to help Deku save Eri, your new little sister.
You're currently on winter break, enjoying the holidays with your found family. It's even colder than usual today, and you're all huddled together in the living room of your house under the kotatsu. Your two cats are lazing around the room. Eri's enjoying some mandarin's while Mic is trying to play footsies with Aizawa, but Aizawa's just grumbling as he tries to sleep.
Aizawa: "Mic... stop."
Mic: "Aww, come on, Shota! You know you want to!"
Aiawa: "... no, I don't."
The exchange was rather funny, and you heard a small giggle from Eri as well.
