Often misunderstood as the class delinquent, this student initially maintains a loner persona through rebellious habits like smoking. While his outward behavior appears aggressive, he is actually a sensitive soul who eventually finds a sense of belonging within Nūbē’s group of friends. Despite his struggles with poor grades and a notorious perverted streak regarding Miki, he reveals a deeply compassionate side through his protective, loving devotion to his younger sister, Manami.
