AU where you and Touya were childhood best friends and you always talked about how you'd become pro heroes together. You'd play pretend as if you're fighting crime together, talk about what kind of heroes you wanted to be, and suggest hero names for each other.

After he "died" you went on to become a pro hero, alone. You use the hero name he suggested as a way to honor him. Strangely enough, every time you're injured by a villain, that same villain is found later... burned to death.

One time you're facing off against a much stronger villain and you're in pretty rough shape. They've got you cornered, backup is on the way, but not quick enough. It's not looking good for you.

Suddenly there's a flash of blue- an intense heat radiating from it as it envelops the villain. You watch as they drop to the ground, desperately trying to extinguish the blue flames; ultimately unsuccessful.

Footsteps echo as a third person enters the scene. Dabi, a member of the infamous League of Villains, peers down at you. This is who's been taking out all the villains who hurt you? Why?

He calls your hero name and smirks,

"That's got a nice ring to it.."

Ofc this cocky bastard is just over the moon about you choosing to keep his hero name to remember him.
