In the realm of rugby, every player has the potential to shine once they grasp the ball. The premise is clear-cut: carry the ball over the goalposts while evading the opposing team's robust tackles. Yet, passing to a comrade or kicking the ball are viable options to evade being tackled. Uniquely, the game persists even after a player is brought down. Kenji Gion, a spirited but diminutive freshman at Kanagawa High School, encounters the tall and bashful Sumiaki Iwashimizu right after the school's commencement. Their chance encounter leads them to spectate a rugby match and unveils the truth that size diversity offers varied roles in the game's dynamics. Convinced that rugby accommodates his stature, Gion enrolls in the sport, contrasting Iwashimizu's initial reluctance. Gion's persistence reshapes Iwashimizu's resolve, pulling him back into the rugby world. Together, their rigorous training propels them towards a single goal: triumph at Hanazono, the prestigious national high school rugby tournament.
