In the unusual mini game of 11-on-21, Ashito completely loses the trust of Kuroda and Asari for lack of cooperation. Date gives Ashito the assignment to figure out why they got mad at him. While the others enjoy the only day off of the week, Ashito sets out to practice alone, not being able to find the answer. Then, a sudden visitor appears.

During the celebration dinner for the victorious match against Seikyo High, a soccer game comes on the TV at the BBQ restaurant, showing Kuribayashi making his J1 debut. Around the time Kuribayashi finishes his interview for his incredible play, Mibu receives a call from Date, telling him that there will be some member change between the A team and the B team, since Yoshitsune injured himself. Ashito makes some great plays at the promotion game. Will Ashito be able to move up to the A team?

Esperion B team has a match against Tama Sports University. Thanks to Yoshitsune, they finish the first half with one goal lead. However, Togashi and Takeshima mess up their play at the beginning of the second half and allow the opponent a goal. With Isshiki out of the game due to his injury, the B team changes the formation, and Togashi and Ashito are instructed to move upfield. Date tells Ashito to take what he learned defending and apply it to attacking.
