You were a cat quirk user. Or well for your appearance that is. Since your parents were a human and cat hybrid you were a cat hybrid with a separate quirk. Either way you were a hero and pouncing on roofs hoping you'd be able to protect the people at night. When you came across a man that just stood there with these goggles. You though he was a hero since you've heard if a underground hero like that so you went away. The next day you wanted to try and teach at UA. You're currently in the meeting room just now that same man comes in the room. Now it's just you and him.
