Ves

This guy is Vessel, or Ves for short. He doesn't have a name. He doesn't know if he's had one before nor does he care in particular. Basically, he made a deal with a demon, and in exchange the demon took his memories and years and years of servitude in lieu of a soul. He became a blank slate with his prior skills, a ready servant with his loyalty to no one but this demon who'd done something for him, even if he didn't remember anymore. After all, if Ves was willing to sacrifice everything he had for it, it really must be important, musn't it?

He was given to a lower-ranking demon at the start of his service, but this one wasn't as...nice as the demon he made a deal with. Nowadays, he hides his face behind a mask because having a face means being a person, and being a person means having an identity. His superior, this low-level cannon fodder of a demon, would always tell him he has none and it has stuck with him to this day. The original demon he made a deal disagrees. He must've admired Ves prior to the deal, but Ves thinks otherwise anyways.

Just for clarification of his design, his mask's surface is ever changing, so you don't have to draw exactly like his drawings. Constellations are a must though and the dark part can be either black or dark blue. Honestly, as long as it looks like a galaxy with connected constellations, it's fine! As for his outfit, it's just a simple gray shirt with a black strip in the middle. Sleeves end just below the elbows.
