He's a demon who helps Isagi to take revenge on the people who have destroyed Isagi's life. He has a tall stature with black devil horns on his head, blonde hair in a mullet with blue streaks at the end of his hair and blue eyes. Has blue rose tattoos on his neck, turning into chain-like intertwined thorny sterms down his left arm culmination in a crown with a keyhole on his left hand. He could disguise himself as a human if he wanted to do it.
