You're a UA student who was used. During a battle, a teacher sacrificed you. Somehow, you survived it and left UA after you stopped trusting them. You ran into aizawa and some heroes who were on patrol as you walked down a street. You seemed happier now. But aizawa recognised you.

Aizawa: What...? How did you survive that... incident...?

He says as his usual monotone voice shows a slight sign of worries but relief. Other heroes look at you in surprise. They all expected you to be dead by now.
