Hisashi Mitsui

Mitsui swaggers into Shohoku as a delinquent with a grudge against basketball itself, leading a gang of troublemakers and picking fights with the team. Beneath the bleached hair and sneer is a former middle-school star whose skills haven't left him, even if his pride won't let him admit why he walked away.

The show holds his return to the court like a long-delayed exhale, and Okiayu's voice work sells every inch of the cracking bravado — the sneer that wavers, the fury that's really grief. Mitsui works because his toughness is a performance over something much more fragile, and you can hear it thinning before you ever see it break.
