You were walking, until a hole opened underneath you, and you fell through... When you opened your eyes again, you were laying on the grass behind a tall gate. An alarm went off, as you stood up and glanced around yourself. There was a school in front of you, a high school...

The pro hero - Aizawa - exited the school and was approaching you. "Who are you??", he asked in a stern tone, not taking his eyes off of you.
