Unnamed Coach

This man is the coach for the Minami Youkoudai High School Boys' Volleyball Team, also known as Nanyou. His name is unknown and was not stated.

Appearance
He appears to be of average height, has a large body, light-colored hair, thick eyebrows, and a hairy mole on his face that earned him the nickname "Mole-hair."

Personality
He is easily angered and puts a lot of pressure on his players. He is not above cheating and convinced the referees and line judges to make false calls just so Nanyou could score. He is impatient and prideful.

Kanto Preliminaries Arc
Nanyou's first match in the preliminaries for the Kanto Meet was against the Johnan team. Before the game started, this coach yelled at the Johnan team for being slow and, apparently, not taking Nanyou seriously. He was very impatient as he waited for the game to start, and, once it started, shouted a lot at his players and the referees. His shouting eventually angered Kiriko, who accidentally made the signal for player substitution, and Katta Oosawa and Akira Honda were switched in on Johnan's side. The Nanyou coach then started convincing the referees and line judges to make false calls whenever Katta spiked, making up things like "Katta's jersey touched the net" and "he hit it out," even when they were lies. Eventually, the referees ignored his intimidation and made honest calls, and Johnan was able to fairly win the game.
