He has long golden hair, wears glasses, and has an androgynous appearance. He isn't good at sports, but he can do them. He is serious and kind-hearted, but he is often jerked around by Go and suffers for it. When he gets angry, he is scary enough to make even ghosts tremble, let alone Go. His parents live abroad, so he handles all the housework himself. He can apparently recite pi to 500—no, 800 digits (which leads the whole class to call him a "genius"). He is so knowledgeable that he's nicknamed the "Trivia Doctor" in class. He is the only one who speaks with a gentle, polite tone. As long as he isn't angry, he is a normal middle school boy.

Gender: Male Birthday: July 26th Birthplace: Tokyo Height: 161cm Weight: 48kg Specialty: Sports Likes: Aoi-chan, Sports, Waka Dislikes: Studying, Green peas Despite his delinquent-like appearance, he has a pure personality and loves sports. His inner thoughts leak out constantly, and he has lost count of how many times he's been scolded by his teachers, his mother, and Rui. His first single, "The Guy in Every Class with an Amazing Special Skill," fascinated the world with its unique GypsyCore vibe. He has experience winning an award in the Japan Pekede Newcomer Grand Prix. He speaks with a "...daze" style (rough/cool), uses "Ore" (casual/masculine) for himself, and goes by the nickname Go. He is a show-off who constantly wants to be popular with girls. Because of this, he often asks Rui for trivia or tips on how to be popular. However, he is not popular. If anything, girls are repelled by him.
