Obanai is a short young man. He has shoulder length black hair with long bangs. Obanai was born with heterochromia, so his eyes are shaped: the color of the right eye is yellow, and the left eye is turquoise. He is partially blind and has almost no vision in his right eye. When he was twelve, his mouth was cut down to his ears, resulting in a scar that he hides under a mask of bandages. Sharp horns. Obanai was a very inquisitive person, but slightly suspicious and behaved.
