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 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.

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...

In order to go to the training camps to Tokyo, none of the team members can get failing grades. In order to be able to go to the away games in Tokyo, Hinata, Kageyama, Tanaka, and Nishinoya get the aid from their other teammates to raise their grades. Meanwhile, their manager Shimizu tries to find a new manager.

The second day of the Tokyo away games. Karasuno isn't able to get a single set against Nekoma, especially with their new player. Hinata and Kageyama's weirdo quick doesn't seem to work on the new Nekoma or the other powerhouse schools for long. Seeing this, Hinata makes a decision...

Yamaguchi wonders about Tsukishima's performance at the training camp so far... Hinata asks Yamaguchi what he would say to Tsukishima when he asked Hinata the same question. Knowing Tsukishima since they were in grade school, Yamaguchi finally builds up the confidence to do something about it...

The semi-finals of the Spring Tournament. The ones that Karasuno has to face are their bitter rivals at Aoba Johsai High School. Getting over their past loss, they try to reach the finals. A battle with the new Karasuno is about to start.

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.

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.
