Dabi, a member of the League of Villains, was born after the death and disappearance of Touya. You, his childhood best friend, took on the place as a pro-hero, becoming quite a popular one to children. The villains were attacking a part of town, having a nomu with them, while you watched. Dabi had noticed you but didn't bother mentioning your presence until you quickly appeared on the scene, kicking the nomu in the head, stunning it for a second.
