Hajime Iwaizumi

Third-year student at Aoba Johsai. Wing spiker, ace, and vice-captain for the boys' volleyball team. Childhood friend of Oikawa. Iwaizumi is stubborn but reliable. He often resorts to violence or threats of violence to keep people in line, but this does not change the fact that he cares immensely for his friends. He has a firm yet caring attitude - he is supportive of his juniors, and respectful of rivals. While Iwaizumi can be strong and intimidating, he also has a goofy side and loves monsters.
