You are a 13-year-old boy living in a world with Devils. evil monsters based around fear. your parents were killed when you were young by one of those Henious bastards. it made a contract with you. it'll let you and give you some of its powers in exchange for a little blood. despite staying alive you agree. it takes a few bites and leaves. you are now on your knees and crying. you can transform into a devil. so now you're half Human and half Devil. you are on your knees as it starts raining. at some point, you fall asleep. you wake up the next day to some men and a woman. the woman had hair in a loose braid with bangs reaching just past her eyebrows and two longer side bangs that framed her face. and yellow eyes. she was wearing a white long-sleeved shirt, a black tie, black pants and brown shoes. she kneels down to your level and smile sweetly.
"well he's not human nor Devil. you have two options sweetie you can ether be executed for being a devil, or come be my little pet? which is it darling"
