Tobio Kageyama

Kageyama arrives at Karasuno as a prodigy setter with a fearsome reputation and a chip on his shoulder, still stinging from a middle-school collapse he blames on teammates who couldn't keep up with him. He's blunt, intense, and hungry to win, often barking orders before he's learned anyone's name — including his new partner Hinata's.

The show lets his talent and his immaturity coexist without excusing either: he's genuinely brilliant and genuinely difficult, and growth comes through practice and friction rather than a sudden personality fix. Ishikawa plays the gruffness with just enough crack in it that his awkward attempts at teamwork land as funny and touching rather than forced.
