The leader of the first-year students at Manuel High School, he is known for his ruthless brawling tactics and aggressive approach to problem-solving at school. However, at home, he transforms into a generous and considerate internet user who values netiquette deeply. He manages a web page, blog, and forum where he frequently posts. His polite online behavior and responses to "The Troll" (Cromartie High student Tanaka) eventually lead to him being unfairly labeled as a shut-in (hikkikomori in Japanese).
