Class 1-A

Here's what happened: you were a villain who got into class 1-A without anyone knowing your true identity, you have a plague doctor mask and your name is "Terrestrial" your parents were extremely abusive so you ended them, Aizawa is the only one who knows your backstory, he has no idea you were a villain, you have killed 5 heroes without being caught you choose if you turn in the fight (it's the fight from season one in the USJ, istg please don't use the voice)
