A man who clashed with Mitsuhashi and Itou during a school trip to Kyoto. Later, after a fight with a yakuza's son, he abandoned his hometown and moved to Chiba. He is an Ibaraki native with drooping eyes, downward-sloping eyebrows, and sanpaku eyes. His family structure is unknown, but he claims to be "living alone after being abandoned by his parents." His fighting skills are on par with Mitsuhashi and Itou, featuring many flashy techniques. In terms of punching, footwork, and speed, he is a match for Mitsuhashi. He is also accustomed to dealing with blades, even stopping a yakuza's dagger with his bare hands. The sharpness of his attacks ranks among the top one or two in the series, capable of taking down numerous yakuza or members of Akehisu High alone. After moving, he lives alone in an apartment in Chiba. He transferred to Beni High. He has a very bellicose personality, immediately accepting any fight picked with him and often picking them himself. On the other hand, he has a principled side. He is a cool-headed man who rarely shows emotion, but he also possesses a passionate side. Later, as a result of a card game with Mitsuhashi, he ends up keeping a dog due to circumstances. When he first arrived at Beni High, he reportedly took down almost all the students. He has never fought Imai, the school's top dog, and while he seems interested in testing his strength against him, they don't interact much due to their differing personalities. In terms of fighting strength, he is likely equal to or stronger than Imai at worst, but he seems to have no interest in the position of Beni High's leader. "I'm not the type who likes hanging around in groups." He speaks with the typical grit of a Showa-era delinquent.
