Gion and Iwashimizu join the Jinko rugby team. Captain Sekizan Takuya imposes a brutal training exercise known as "The Turtle" on Gion, who wants to practice tackling.

As the members of the rugby team are feeling the results of their training camp, Komori arranges a practice match against Todo-dai Sagami. Their opponents placed second at the Kanagawa prefectural preliminaries... Sekizan is fired up at the prospect of facing just the type of opponent he hoped for! But Yoshida, the team's advisor, calls the rugby team's activities mere "ball games." Jinko versus Sagami... Will Yoshida see ball games or something more?!
