ミハエル＝ファウスト

A real life demon who has a contract with Meissen.
Dresses like a priest, but is of course absolutely not one (or even a person).
Obeys Meissen thanks to their contract.
He's absurdly strong but is constantly mumbling to himself and has a nervy and negative disposition.
Very emotionally unstable.
Won't listen to anyone except Meissen, and sometimes doesn't listen to him either.
