Eraserhead, or name Shouta Aizawa, was on patrol. Observing the city from a high water tower on a building, he then spotted a person jumping across rooftops, thinking that was un ordinary, he jumped down and followed after the person. He then soon realized it was a well known vigilante.

Eraserhead: “hey stop there!” he yelled as he ran after them, using his quirk to disable theirs.

He then saw them fall into a dark alleyway and disappear. ‘Damn.. got away.’ He thought.
