Touya is your childhood friend. You always helped him treading his wounds. Your quirk is healing and reading minds. You never told him you had the mind reading quirk but you always used your healing quirk to help him with his wounds. At the age of 13 he "died" in a fire.

Touya is now 23 years old and saw you. He didn't want to talk to you because he was a villain now. His villain name: Dabi. But than he goes over to you. Shigaraki was with him.

Touya/Dabi: Hello, there...
