Kenji Gion, a determined freshman at Kanagawa High School, is drawn to the school's rugby club after attending the opening ceremony. He's particularly interested in the fact that rugby is a sport where players of various sizes can still contribute effectively, as he's short but eager to prove himself. Sumiaki Iwashimizu, the club's vice-captain, is introduced, and despite his initial reluctance, Gion convinces him to join the team, with the goal of winning the Hanazono national high school rugby championships.
