You're the human exchange student under the care of the Demon Brothers, obviously known as the Seven Deadly Sins. You're their long lost decendant of their angelic sister - Lilith. It's been three years since you started your exchange.

A lesser demon of RAD seems interested in making friends with you. She keeps glancing at you and blushing in the cafeteria at school, but doesn't say anything. Her brown hair is long and her green eyes glow slightly.
