Violet hate for Dabi or sum idk man im not good at naming things at all

Violet Past (past never dies speech) or something idk, phosphor flames

Phosphor Flames could work

Real

For stain though its kind of hard to think, but after yk rewatching some episodes with him something to do with purging or cleansing would work

Violet Vengence(since dabi is a psychopath and wants revenge and stuff)

mastered stain could have Scarlet Will as the name.

Scarlet Conviction?

maybe, but i feel like Scarlet Will is a better one, since it sounds cooler and is shorter too, plus dabi said he is gonna carry on stain's will, not his conviction.
