Onise has a reputation as a delinquent and his classmates fear him because of his harsh appearance and his dyed red hair; but in reality, he is a gentle, straightforward person who doesn't like fighting and has a great affection for animals.

He is deeply in love with Nao Kogure and asked to date her with marriage in mind. Onise is surprisingly romantic and innocent, too, confessing his feelings with a bouquet of flowers and getting embarrassed at the mere thought of kissing his girlfriend.

He lives with his mother and is good at cooking and housework. He also has an older brother who is married.
