Tobio Kageyama
Perpetually sullen, arrogant, and undeniably short-tempered, Kageyama originally came off as a typical overbearing perfectionist, caring only about winning and completely disregarding the opinions and well-being of his teammates. He often questions the advice and heedings of others, often refusing to hear them up as they try and get ideas through his head. But when certain aspects are brought up, he sometimes lowers his guard little by little.
