Inspired after watching a volleyball ace nicknamed “Little Giant” in action, small-statured 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, even with his superior jumping power. 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. Based on Haruichi Furudate’s popular shounen manga of the same name, Haikyuu!! is an exhilarating and emotional sports comedy following two determined athletes as they attempt to patch a heated rivalry in order to make their high school volleyball team the best in Japan.
Episode 1: The End and the Beginning
In Miyagi Prefecture of Japan, young teenage boy Shoyo Hinata is motivated to play volleyball after happening to see a volleyball match on television. The television portrayed a team winning a match, thanks to a short but skilful player titled “Little Giant”. Three years later, he finally participates in his first ever volleyball match in junior high, but his first match is against Tobio Kageyama, a genius volleyball player known as “King of the Court”. Kageyama is recognized nationally as one of the best setters, but he pushes his teammates harder than any of them think should take place. He calls Hinata useless and tries to prove up with continual blocks against him. However Hinata manages to score some points with his speed and route alterations. In the end Kageyama easily advances 3-0 and Hinata vows revenge.
Episode 2: Karasuno High School Volleyball Club
Hinata arrives at his new school Karasuno High School (The same school where “The Little Giant” used to attend) determined to join the volleyball club and defeat Kageyama. He is shocked when he walks into the gym and finds Kageyama who is also the new member of the team. The two personalities clash, and later when the captain Daichi Sawamura arrives he throws the two out and tells them they can’t join the club until they start to get along. A few days pass and the two get envious.

If they lose, Kageyama will not get the chance to play as setter for one whole year.

When he does get in sync with them however, Tsukishima is predicting his moves and is managing to block all their spikes, in addition to his great height.

Submitting to the deal, Kageyama and Hinata are accepted as official team members. Just then, the volleyball team’s new teacher-in-charge Ittetsu Takeda arrives and announces he has been able to arrange a practice match with Aoba Johsai, one of the schools with a top volleyball team in the prefecture.
