Seven

This is a cursed angel lamb named Seven, who's in the same story as my catacomb demon kids.

He (I use "he" lightly, because it doesn't really matter to him) is very over-confident, which led to him being cursed by a demon who was too strong for him, and then he was stuck in Hell. He used to have the power of light, but the curse turned his powers into inky darkness. He was self-serving to begin with, but the curse is slowly turning his mind making it gradually more animalistic and irrational. All he has to do is find some kind of a thing/cure that will take the curse from him and he can leave. (I don't know what that would be yet.) None of what's afflicting him could change his imposing and cocky attitude, but it does add a layer of detachedness sometimes.

I kind of want Seven to maybe make fun of Hell's religion and get on Sulphur's bad side, but then they're stuck together somehow and learn they're more similar than they think--which only make them dislike each other more... or something like that.
