Fukuda suggests that Ashito and other new Esperion Youth players play an intrasquad game. Anyone who proves their worth in the game will be promoted to the A team. All new players are excited at the prospect of joining the A team. Ashito, playing his favorite forward position, starts the game out well. However…

While still feeling unconvinced, Ashito makes up his mind that he must try and learn to be a full-back. He goes to practice, wanting to figure out Fukuda's intention. However, being unfamiliar to the position and disliking defending, Ashito doesn't quite get the meaning of "shuffle" and feels out of place.

Advised by Takeshima and Anri that he should study Kuribayashi's movements, Ashito pours over the broadcast of the J1 match to see Kuribayashi's play. Combing over the past footage of Kuribayashi's play, Ashito realizes that what set Kuribayashi apart is how he turns his head. Ashito tries to incorporate it in his practice right away, but it only confuses him. In his teammates eyes, that confusion looks like being unmotivated for having to play a full-back.

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.

Esperion B team starts to show some signs of improvement as they face undefeated Musashino in the next match. When the team needs to be united more than ever, Takeshima and Togashi, who are the key defenders of the team, have a huge fight. Tachibana, with a strong resolution that he will do anything he can to win the next match, goes to Yuma to ask him what happened between Togashi and the promoted players in the past.

The game against Tokyo Musashino is the climax of the Tokyo Metropolis League for Esperion B team. Although the team has worked on countermeasures against Musashino, the air is still tense within the team and there's a clear sign of anxiety on the faces of many of them during the warmup. But right before the game starts, Takeshima disappears from the locker room with his girlfriend, Tae.

Esperion B team bitterly allows the first goal to Muto, the playmaker of Musashino. With Musashino one step ahead, second-year Sugawara suggests that they go back to their original play style that relies on short passes. But Tachibana, Togashi, and Takeshima insist on continuing with the direct approach they've been practicing. To the disconcerted players, Date starts giving concrete instructions for a change.

The match between Esperion and Musashino will determine who will dominate the Tokyo Metropolis League. Musashino's ace, Kaneda, takes advantage of the weak coordination between Togashi and Takeshima, giving Musashino a go-ahead score. Right before the end of first half, Kuroda injures himself due to his desperate defense play. During the halftime, Asari blames the center-backs, but Date disagrees with him. Togashi has resented Takeshima for a long time, but now…

Thanks to Ashito's great bird's-eye view, Esperion B team succeeds in bringing down the defense of Musashino and scores a tie-goal. Esperion gains the momentum, while Musashino is confused by Ashito's flexible play. Kaneda can't hide his frustration at seeing just how much Ashito has improved. The desperate battle between the top of the Tokyo Metropolitan League, Musashino, and the challenger, Esperion: Who will win in the end...?
