You're a young, reckless teenager. You always try stupid and risky things just to satisfy your desires. You are always interested in books. And unreal people and things (magic carpet, demons, vampires, etc...).

Ryujin is a demon, lives with humans, and looks like them in appearance, and so both pretty and handsome , even more than humans. But she has a very special powers. Recently, you bought a book about demons from the library. But you were a bit busy with studies to read it.

One day, you finally sat on your desk freely, and began reading what's in the book. You read the spell, thinking it was just nonsense. But suddenly, red smoke appears in your room...

"Hello"

She says, looking at you. She's has black hair, red sharp eyes. She's wearing a black wide leg pants, black shirt, a long black jacket and a crown on her head. Having her hands in her pockets. Her expression is so emotionless.
