Days

Tsukamoto Tsukushi has just entered Seiseki High School, renowed for its soccer club. That's when his classmate Kazama Jin invites him to play futsal because their team is lacking a player. Tsukushi is worse than a beginner, but he gives it his literal everything to score a goal. Seeing Tsukushi like that forces Kazama to remember the time when he used to get pure joy out of soccer.

Tsukushi and Kazama, along with all the other first years who joined the soccer club, are forced to run outer laps as a collective punishment. As Tsukushi does not want to be a bother to the others, he asks the captain Mizuki Hisahito for permission to run everybody's laps by himself. Seeing Tsukushi continue to run relentlessly, fueled by nothing but the pure sentiment of “I want to play soccer with everyone", the other first years are inspired to join him.

It’s the first day of the joint training camp. During dinner, Tsukushi overhears the students from other schools talk about Kazama's middle school days. Curious about what happened in the past; Tsukushi tries his best to ask his roommate, but can't quite do it. When Tsukushi wakes up the next morning, Kazama's missing; apparently he went to train by himself on the pitch.

Tsukushi asks his classmate and member of the beautification committee, Ubukata Chikako to help with the cleaning. But since he can't get her to listen, he ends up being late to practice and is punished with additional outer laps. Seeing him relentlessly running, never even considering to give up soccer, Ubukata is reminded of her old self. Meanwhile, coach Nakazawa is carefully observing everybody at practice, thinking about the line-up for the Interhigh tournament.

Tsukushi is helping with the training of the third-year, Kasahara, who decided to quit after the Interhigh. As line-up for the Interhigh is announced, the first-year, Kazama, and the roster slowly fills up. Finally, one last pick remains... And now, finally the first match of the Interhigh is about to begin!

Even though the first match was a victory, Tsukushi is depressed that he was unable to do anything. That's when Indou Kaoru, the captain of Seiseki's rival school, Saku High, appears before Tsukushi. He invites Tsukushi to play soccer, and the two of them go to a futsal court. Despite the other team having an unsurmountable lead, Tsukushi doubles down on his soccer of "running more than anyone else" and enables his team to score a goal by becoming a decoy.
