A student from Byakudan Senior High School's Class 2-4. He’s a classmate and childhood friend of Yuuya; they often played together when they were little. His cheerfulness and sociability make him the class' moodmaker. He is also a member of the Basketball Club. Ever since childhood he has loved exercising and running around the neighbourhood. Teachers give him good grades, and he’s willing to take on chores. However, because of his personality he often gets bossed around by Student Council representative Mitsuki. He thinks himself to be Yuuya's best friend, even though Yuuya doesn't hold any specifically friendly thoughts about him.
