Nickname: Pudding Head, Nekoma's Brain (also the Spine and Heart) Features: He isn't particularly athletic or fond of sports, but he has played with volleyballs since he was a child. He dislikes the strict hierarchical relationships typical of sports clubs, even with just a one or two-year age gap. Though he looks quiet, he says what's on his mind, and there's a significant gap between his usual self and his demeanor during matches. He will even shout when truly angry. He is childhood friends with the team captain, Kuroo Tetsuro, whom he calls 'Kuro.' He is notably harsh toward Lev.

He has a tough personality and tends to be very blunt, which can sometimes kill the mood.

He values 'guts' above all else. Kenma calls him 'Tora.' He is the only team member who frequently bickers with Kenma. They initially clashed due to personality differences, but Fukunaga's habit of splashing them with water to mediate helped them move past it, and they are now close friends. He sports a mohawk like Travis Bickle, with the center strip dyed a fluffy blonde.
