Playing rugby can make anyone a star, regardless of their size, as the simple objective requires carrying the ball past the goalposts while dodging the opposing team's tough tackles. Passes and kicks can be utilized as well, and the game doesn't end when the ball carrier is tackled, unlike other sports. At Kanagawa High School's assembly, Kenji Gion, an enthusiastic freshman, meets Sumiaki Iwashimizu, a tall and timid student who invites him to watch a rugby match. Witnessing the variety of roles available for players of all shapes and sizes, Gion signs up to join the team, whereas Iwashimizu decides against it. Gion is determined to convince Iwashimizu to join him, and they both train tirelessly to compete in the national high school rugby championships at Hanazono and emerge victorious.
