After losing in Interhigh, Karasuno High is busy practicing. As Coach Ukai wishes for more practice matches for the team, Ittetsu Takeda barges in with great news: Karasuno has been invited to take part in Nekoma's training camp! Kageyama and Hinata get lost during a run and ends up meeting with Shiratorizawa Academy's Ushijima. After Ushijima claims that the only good player from Aobajōsai High is Oikawa, Hinata challenges him.

Hinata, Kageyama, Nishinoya, and Tanaka are devastated by the possibility of not going to Tokyō if they fail any of their exams. When forced to study, the second years go to Tanaka's place, but Kageyama and Hinata are having a harder time with their reluctant tutor, Tsukishima. Luckily, Hitoka Yachi, the new manager Shimizu is trying to draft, proves more helpful at teaching the duo.

Yachi feels conflicted about joining the volleyball team, but after watching their practice match against Ōginishi High, she begins to see the charm of the team. However, she is having a difficult time expressing her feelings to her mother, afraid that she might disapprove. Luckily, Hinata helps her overcome it by showing to her that even a small role such as a "Townsperson B" can be great.

After Hinata and Kageyama finish their supplementary exam, Saeko Tanaka takes them to join Karasuno team at Tokyo training camp. Now they're on the team, Karasuno wins their first match on the day; however Eikichi from Shinzen High manages to touch on Hinata's quick's. Later on, Hinata meets the half Russian player from Nekoma Lev Haiba; Lev promises him that he will be the first one to stop his quick.

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 oddds. 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...

Tsukishima begins to think that he shouldn’t put so much effort in training anymore like his brother did, to avoid being disappointed if he fails. Despite practicing very hard, Akiteru failed to become a regular player for Karasuno due to the number of more talented players on the team, including Hinata’s idol, the “Little Giant”.

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 Ohgi Minami'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 Inter-High 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.

As Daichi exits the court, a second year has to push through his self-doubt to lead the team in his stead. On top of that, Yamaguchi comes in to serve but gets nervous.

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!
