High school student Subaru Hasegawa arrives at the Keishin Academy to coach the five members of its elementary school girls' basketball team.

By studying the strengths and weaknesses of each girl, Subaru devises a specialized training plan to prepare them for their big game on Sunday.

With the score close, the pressure's on for the girls' basketball team to eke out a win against the boys using the techniques they practiced.

At a sleep-away basketball training session, the girls discover that Takenaka will be on their team in an upcoming game between classrooms at school.

As the session continues, Takenaka has something important to say to Maho. Later, Takenaka and Hina disappear, and the others go to investigate.

Subaru's friends are suspicious about his recent behavior. Airi reveals that she's afraid of water and is worried about the upcoming swimming class.

Aoi confronts Subaru, accusing him of sacrificing his grades and his dream of restarting his own school basketball team for the sake of the girls.

Maho invites everyone to her beach house for a relaxing day of food and play. Hina gets to spend some special time with her sister, Kagetsu.

Aoi and Subaru go with the team to another sleepaway camp for their first basketball experience away from school. The camp is not what they expected.

The team continues to train and enjoy the great outdoors, and after some heartfelt talk, a five-on-five match is arranged against the Suzuridani team.

The team shows off the results of all their hard work and determination in their match against the Suzuridani team as Subaru and Aoi look on.
