It began with a chance meeting... The day of the Jinko High entrance ceremony; Gion Kenji, a first year insecure about his height, decides to join the rugby team after watching the team practice.

The practice game against Keijo High, one of Kanagawa's top four teams begins. Iwashizumi faces off against Miyuki Atsushi, a friend he accidentally injured during middle school.

Jinko may be making a comeback in their game against Keijo thanks to prodigal first-year, Oharano Etsugo. The match begins poorly under their opponents' skillful assault. In order to change the flow of the game, Sekizan subs in the amateur Gion! Will Gion have a chance to shine in his first match? The match between Jinko VS Keijo finally comes to a close!

With their new coach Komori, the new and improved Jinko Rugby Team begins the second day of their training camp. Contrary to Gion's excitement, a fight breaks out between teammates. The first thing the hot-tempered sore loser Ebumi ever became passionate about... was rugby. And because of his attitude, he can't tolerate the lukewarm approach of his teammates!

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?!

Second place school Todo-dai Sagami continues to impress... Not only are they strong, but their clever play produces advantageous situations for them throughout the game. Their barely legal plays and words mess with the Jinko players... The game begins going in Jinko's favor once Ebumi joins the game, but the stronger Sagami team tries to take the game back by force!! Do the savage Sekizan and the rest of the Jinko team have any chance at winning?!

With their game against Todo-dai Sagami over, the Jinko rugby team has even more work to do. At Komori's suggestion, they engage in a slightly unusual practice session on the beach! While there, Gion begins to wonder if there's a better position for him on the team... After receiving advice from Oharano, Gion and Kamo head to Ryoin Academy to scout out the best flanker in Kanagawa!!

Gion and Kamo have arrived at Ryoin Academy to spy on the team. Among the Ryoin team that overwhelmed its opponent, twin flankers Kirishima Sekito and Kokuto stood out from the rest!! Along with their 92 centimeter 98 kilogram ace Zanba Ryujin, the two feel firsthand just how amazing Ryoin Academy is. Gion's path has become clear to him, while Kamo is overwhelmed by the amazing prowess of Ryoin. On their way home, they stop by a sporting goods store where they run into Sekito and Kokuto...

omori meets with his former college teammate Tomie Yujiro. Time flies as they have fun catching each other up on how they've been doing. When it's time to leave, Tomie tells Komori that X Day will come before the start of summer break before going home... Then one day, someone submits a club resignation form to Yoshida-sensei--and Komori understands the meaning of Tomie's words.

Encouraged by Komori and his friends, Sekizan begins practicing even harder. Though everything appears to be going well for Jinko, X Day isn't over yet!! Ise is unable to focus on rugby because of his situation at home. HaChioji does his best to be considerate of him, but he's spurned by Ise's older brother Haruki... Will another team member be leaving the Jinko rugby club?

With the Sugadaira training camp starting tomorrow, Sekizan and Hachioji take their brief day off to go out together. In contrast with Umeno and Rie's wild fantasies, the two of them are simply going to a lunch meeting at Coach Komori's house. When Gion discovers what they're up to, he tries to go with them, but Sekizan sends him away! Then the persistent Gion comes up with a plan to accompany them to lunch!!

With the Ryoin game coming up tomorrow, Iwashimizu spends the night anxious. Miyuki realizes his friend's emotional state and shows up at his inn. When Gion, who had been training at the field alone, joins them, the three of them begin a secret training (?) session. While hanging out with friends and teammates, Iwashimizu realizes anew how fun rugby is, and all trace of anxiety towards tomorrow's game disappears from Iwashimizu's heart!!

The team's game against Ryoin has finally started!! They may be the second string, but Ryoin is still the strongest team in Kanagawa! Jinko is tossed about by Ryoin's refined play... is what they were expecting, but the Jinko team that has gotten stronger over the past few months fights on equal footing against Ryoin! As the fierce battle continues, an ominous atmosphere surrounds the third-years...?

The bad blood between Matsuo and the other third-years remains... but right now... right now making the "Strongest Team in Kanagawa" standing before us remember our name comes first!! Despite their inconsistent coordination, Jinko desperately holds on, finally drawing that man to the field... The Jinko VS Ryoin game heads towards is magnificent conclusion!
