The second leader of the Crazy Diamonds, Japan's largest and most feared biker gang, is known for his respect towards his brother who passed away and left him in charge of the gang. He embodies toughness, honor, and loyalty to his fellow members. However, when he gets nervous, he tends to shout which makes it difficult for him to confess to women. Despite this, he loves dogs. After fulfilling his duties as a member of the gang, he plans to pursue a career in carpentry.
He killed Fujisaki in the boys changing room in a fit of rage and later was executed after being found out in the trial.
