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.

After losing to Aoba Johsai at the Interhigh, the Karasuno High Volleyball Team is working their hardest toward the Spring Tournament. In the meantime, it's decided that they'll be heading to Tokyo for a training camp with Nekoma High and a handful of other powerful schools. They team is practicing hard, and not day during their run, Hinata and Kageyama get too excited and end up lost, and end up meeting someone rather unexpected...

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.

Yachi joins the Karasuno High School volleyball team. Despite being rather nervous still, she finally starts to notice the charm of the team. However, she has a hard time telling her mother that she's becoming the manager of the volleyball team. Seeing that, Hinata...

With the supplementary tests over, Karasuno heads to Tokyo for the away games. Karasuno is having a hard time dealing with powerful schools like Nekoma, Fukurodani, Shinzen, and Ubugawa High Schools. During their matches, they notice a new face on the Nekoma team...

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...

Hinata and Kageyama are at odds. Keishin decides to take Hinata to his grandfather, who lead Karasuno to the nationals. Meanwhile, Kageyama runs into...

In order to achieve a new form, Hinata and Kageyama start practicing on their own. The other members of Karasuno have also started practicing on their own to better themselves, and they have shown some evolution. However, Tsukishima seems indifferent about change and one day after practice, he is asked to serve as blocker for Kuroo and Bokuto's spiking practice.

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 members of Karasuno continue to strengthen the new things they've learned while at the Tokyo training camp. However, Hinata and Kageyama still can't get their quick down. Kageyama is anxious about Hinata losing his spirit and tries to do a normal toss during a practice match, but...

The week-long training camp is finally on its last day. Karasuno's final opponent is Fukurodani High School, and they're determined to win at least one set against the powerhouse school. Are they going to be able to show the fruits of their labor?

The training camp comes to a close with a barbeque battle. Bokuto talks about rivals from all over the country and the prepare for the upcoming Spring Miyazaki Prefectural Tournament.

The first day of the Spring Tournament Miyagi qualifier is finally here. Hinata tries to trush to the bathroom, but he runs into Ohgiminami's Towada, who plays on the team they're up against first. With various feelings in their hearts, the battle towards nationals begins.

Their first match to get through to the qualifiers is a match against Kakugawa High School. At the center of Kakugawa's team is a first-year named Hyakuzawa, who is 2 meters tall. At first, Karasuno has trouble dealing with Hyakuzawa's immense power and height, but...

Just about 2 more months until the qualifiers. Tsukishima's brother invites him to practice with his own team, Kageyama goes to observe a certain team, and Hinata and Kenma promise to have a match that they wouldn't be able to repeat.

Karasuno is finally playing in the qualifier prelims. Their first opponent is the 4th best team from the Interhigh prelims, Johzenji High School. Their motto is to play. What will Karasuno do against their rather unconventional playing method?

Johzenji's carefree rhythm almost breaks Hinata and Kageyama, but they manage to regain their cool with Sawamura's help, and continue the match. Meanwhile, Johzenji's manager, Misaki, tells the team how she really feels about them.

The second match of the Miyazaki qualifier prelims, and both teams give it their all from the very beginning of the game. Meanwhile, Karasuno's fearless leader, Sawamura, is hit with an accident, putting Karasuno in a pinch. The one who stepped up in the time of trouble was...

Karasuno can't get back into rhythm without Sawamura, and are having a hard time playing to their full potential. Meanwhile, Hinata battles it out in the air with Wakunan's ace, who has a similar playing style to the Little Giant.

Karasuno manages to make it to the semi-finals. Which ever team wins the match between Aoba Johsai and Date Tech will be their next opponent. Date Tech was considered to be the underdog against Oikawa and Aoba Johsai, but they have a new strength on their side...

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.

Karasuno is facing a completely different Seijoh now that they've called in Kyotani. Karasuno can't seem to gt their rhythm together, meanwhile, Seijoh seems to pick themselves back up. When the flow of the game seems like it's going to change drastically, Karasuno...

As Seijoh takes the flow of the game, Keishin sends Yamaguchi out as a pinch server. Yamaguchi ran away from the Wakunan match, but now is he able to turn around this match?

The final set of the qualifier semi-finals continues with Karasuno and Seijoh. As the teams go neck and neck, both teams put everything they have into this final set.

Neither team is willing to let the other team get ahead. They're both reaching their limit, yet the match continues. They proceed into the final battle to determine who will make it to the finals.

After defeating their fated rivals, the Karasuno High School Volleyball Club finally move on to the finals of the Miyazaki Prefecture Qualifiers of the Spring Tournament. They will be facing the strongest school in the prefecture, Shiratorizawa Academy. Their battle for the "absolute king" in order to get the one ticket to nationals beings!
