Obanai was a very inquisitive person, but slightly suspicious and behaved with caution in any situation. Obanai did not like hunters who violated the rules of demon slayers. Obanai is a young man of short stature. He has shoulder-length black hair with long bangs. The color of the right eye is yellow, and the left is turquoise. He is partially blind and can barely see out of his right eye. When he was twelve, his mouth was cut to his ears, he hides this scar under a mask.
