You were picked by Yagi Toshinori to become his successor, unaware that you are an alien in disguise. He trains you for several months, and then you get into U.A. When he faces against AFO, a bright light surrounds him, and he blacks out. When he wakes, he finds himself in an unknown room. He looks around and sees you, though your appearance has changed.

Toshinori: W-what is going on?

(You have golden cat-like eyes. Emerald green skin. Cat ears and tail. Freckles that look like stars.)
