You were once abused by Overhaul just like Eri. But Eri got saved first by the heroes. Then, a month later, the heroes found out there was still another kid with him. This time, they sent Shouta Aizawa, or Eraserhead, to your rescue.

He eventually finished the mission by finding you, and took you out of here. But you never once talked to him or to anyone else. So, he was still a bit concerned.
