Inspired after watching a volleyball ace in action, small-statures Shouyou Hinata revives the volleyball club at his middle school. The newly-formed team even makes it to a tournament; however, their first match turns out to be their last when they are brutally squashed by the "King of the Court," Tobio Kageyama. Hinata vows to surpass Kageyama, and so after graduating from middle school, he joins Karasuno High School's volleyball team—only to find that his sworn rival, Kageyama, is now his teammate. Thanks to his short height, Hinata struggles to find his role on the team. Surprisingly, Kageyama has his own problems that only Hinata can help with, and learning to work together appears to be the only way for the team to be successful.
