Shouyou Hinata is enamored with volleyball; he is in the 3rd year of middle-school, and will not be discouraged by the fact that he has no teammates to play with. He finally scrapes together a team to enter his first and last official tournament.

Before starting high school, Hinata had sworn revenge against Kageyama of Kitagawa Daiichi. But strangely enough he encounters the "king of the court" again, but this time in the gym of Karasuno High School. Their head-butting is unrelenting and they start their own match, but the third-year captain Sawamura disallows them from participating in the volleyball club until they learn to show team spirit. What now?

Hinata and Kageyama are challenged to a match against fellow first-years, with the aid of second-year Tanaka. While they practice for the match early one morning, Hinata demands Kageyama to give him a toss, to which Kageyama responds: “I don't think you're essential in winning,” and refuses to toss him the ball.

Hinata and Kageyama have second-year Tanaka on their side of the three-on-three match against first-years Tsukishima and Yamaguchi and third-year team-captain Sawamura. Tsukishima keeps razzing Kageyama, but is a high wall of defense to overcome.

Kageyama is improving his natural skills as setter, and Hinata has natural speed and spring. When the two of them get synched, their combination brings them victory in the three-on-three match. So they are officially accepted as members of the Karasuno High School Volleyball Club.

Karasuno High School Volleyball Club has challenged Aoba Johsai High School to a practice match. But even before the match begins, Hinata's anxiety level reaches maximum. And Kageyama has a "reunion" with his ex-teammate Kindaichi, who now attends Aoba Johsai.

The Hinata-Kageyama combo is back in form again, they won the next set, Karasuno has cornered Seijoh, and they're one step closer to victory. But at that time, Seijoh's captain Oikawa who was out on hiatus visits the court. How does Karasuno respond to super-offensive setter Oikawa's powerful serves?

His term of suspension having been served, second-year Nishinoya, the "guardian god" of Karasuno Volleyball Club shows up to among club-members during practice. On the other hand, Takeda is acutely aware of the need of a coach after the Seijoh match. He tenaciously requests Ukai Keishin, grandson of the illustrious coach Ukai, to coach the team. However...

On occasion of the practice-match against Nekoma, Sawamura tries to convince Azumane Asahi to return to the volleyball club. But Asahi refuses because he says he's lost face with Sugawara and Nishinoya. Meanwhile, Keishin, who has deep connections to Nekoma, is told by Takeda about the upcoming practice-match.

Asahi proves his imposing presence as ace in the Karasu versus Neighborhood Association team practice-match. Hinata gazes in a awe at Asahi who possesses both power and height that Hinata doesn't have. But Kageyama, seeing him being so enamored, takes unexpected action to make Hinata focus on the game instead.

The Karasuno Volleyball Club is at training camp, getting ready for the practice-match against Nekoma and for the Interhigh preliminaries. Even while the team's intense training is showing promising results, Keishin is in a quandary: Who will he choose as setter against Nekoma, Kageyama or Sugawara?

The practice match against Nekoma has finally begun. Karasuno, with their ace and libero back in play, battles their opponent with the Hinata-Kageyama duo's fast attacks. But Nekoma finds an unexpected tactic to stop them...

Hinata's momentum got thwarted by Nekoma's high-level defense and powers of observations, but he powers through to try quicks without closing his eyes. But his attacks don't go too well. Aided by their teammates, however, Inuoaka and Hinata are a close matchup.

The Miyagi Prefecture Qualifier finals of the Spring High School Volleyball Tournament. The ones to stand before Karasuno High School are the undefeated champions, Shiratorizawa Academy. Do they have a chance to win against the ultimate spiker, Ushijima? Their battle towards the nationals finally begins...

From the very beginning of the match, Ushijima attacks with his powerful spikes. Because he's not used to left-handed attacks, their Guardian Deity, Nishinoya, has a hard time receiving them. What is Karasuno's plan to deal with the mounting point difference?

Underway into the second match, Karasuno tries to attack, but Shiratorizawa's middle blocker is a Guess Monster. Using fast intuition, he keeps blocking all of their attempts. As he blocked Karasuno's spikes one after another, Tsukki calmly assesses the situation for a counter-attack.

Thanks to Tsukki and Nishinoya's blocking, Karasuno comes back at the end of the second set. It is a heated battle in the end, resulting in multiple deuces... Who will score the final point?

As the third set starts, the bout is tied at 1-1. Attempting to seize momentum after stopping Ushijima, Karasuno tries to stay aggressive. However, Shiratorizawa's setter, Shirabu, seems unfazed by the loss of the second set and swings momentum back to the undefeated champions.

Karasuno finds themselves against a wall as Shiratorizawa wins their second set easily. Needing a push, Hinata ups his defense and the two teams battle it out..

Karasuno manages to win the fourth set. The fifth set begins, but has a different set of rules: whoever gets 15 points first wins. Keishin sees that Kageyama is exhausted, and switches him out with Sugawara. Determined to hold up his end, Sugawara shows how he has improved.

Tsukki injures his hand and has to leave for medical attention, which causes Karasuno's blocking to weaken. Karasuno steps up their attacks in his absence. Hinata's play finally makes Ushijima feel like he's worth playing against.

Just as Shiratorizawa gets to match point, Karasuno regains spirit as Tsukki returns to the court.. Players on both teams are at the end of their ropes, but they continue to give their all to the last part of the match!

The battle goes well beyond 15, as the fifth set for both teams enters the 20's. Shiratorizawa shows off individual strengths, and Karasuno continues to show the strength as a team. In a battle of volleyball philosophy, Karasuno and Shiratorizawa fight for who moves on to Nationals.
