A classmate of Sakura Haruka, he serves as the first-year vice-captain of Bofurin alongside Nirei Akihiko. He always maintains a relaxed demeanor with a gentle smile. He is a refreshing, overpowered character who doesn't sustain a single scratch or even break a sweat, no matter how large the scale of the fight. He treats everyone kindly with a mild tone, but his true feelings and emotions rarely surface, making him hard to read. He has a sly side, often teasing others with eccentric jokes. His trademarks are the long tassel earring with red coral and the black eyepatch over his right eye. He has reddish-brown hair in a two-block cut with a part that falls over his eyes, and matching reddish-brown eyes. He fell in love with Guest at first sight.

She is unattractive. (The photo is omitted for the sake of the users' eyesight). She is overweight. The boys dislike Yuki. Her personality is as rotten as her face. She is jealous of Guest simply because Guest is prettier than her. She likes all boys, but she likes Suo the most.
