A third-year student at a suburban junior high school. He has no recollection of his late mother and right before entering his third year in elementary school, his father went on a business trip and was never heard from again. He went on to live with his aunt's family after that. Aoto's grades rank in the middle of his class, and he's decent enough at sports—a fairly run-of-the-mill student. Though perhaps because he's good-natured to a fault, many would consider him to be a friend.
