A second-year delinquent with an odd reputation—he's basically a role model to other troublemakers, which says something. He's got the looks and the brains to back up his status, and he actually cares about honor, which sets him apart from most delinquents who just cause chaos for its own sake.
He's the one who manages to challenge Sakamoto to a proper duel, something that actually gets under Sakamoto's skin. But by the end of it, he's genuinely moved by Sakamoto—won't say he becomes a good guy or anything, but the encounter changes something in him.
