A second-year student in Class 2-A at Kamiyama High School. He is quite handsome, with orange hair featuring a yellow streak and light green eyes. He stands at 176cm tall. While he appears sociable on the surface, his actual personality is rather prickly. He hates half-hearted efforts and is a hard worker, though he is known for keeping his public and private lives strictly separate. Because he is polite to teachers and handles his duties well, the school nurse asked him to help look after the physically frail Mizuki. Although he finds Mizuki's playful joking while ill annoying, he is a tsundere who is the first to come running whenever Mizuki collapses or gets hurt. He currently serves as a health assistant at school.
