Lacking what is considered the most important asset in basketball, Sora Kurumatani has struggled with his short height since the inception of his love for the game. Despite missing this beneficial aspect, Sora's unwavering drive never allowed his small stature to dictate his ability to play, believing strongly in trying his hardest and persistently practicing to prove his capability. In hopes of satisfying his mother's wishes, Sora enters Kuzuryuu High School to become a member of the basketball club and compete wholeheartedly in tournaments. However, Sora is disappointed to find out that the boy's basketball team is nothing but a retreat for punks who have no interest in the sport. Sora also comes to learn that brothers Chiaki and Momoharu Hanazono—whom he becomes acquainted with—have also lost their once spirited motivation to play. Determined to revive the basketball team, Sora challenges the boys to a match against him, where his quick feet and swift movements overwhelm the group. Gradually affected by Sora's impressive skills, sheer effort, and tireless devotion to basketball, the boys unexpectedly find their burnt-out passion for the game rekindling once again.

Rugby is a sport where anybody can be a star when they hold the ball. The rules are simple: one player has to carry the ball past the goalposts across the field while avoiding the other team, who are allowed to use all their force to knock the enemy down. However, the player can pass to a teammate behind them or kick the ball before they are tackled. Unlike other sports, the game continues even when the person holding the ball is taken down. Kenji Gion is a short but feisty high school freshman at Kanagawa High School. Right after the school's opening ceremony, he meets the tall and timid Sumiaki Iwashimizu, and the two of them get an invitation to observe the rugby club. When Gion watches the match, he realizes that even though big and tall guys have an advantage, there are positions for people of all shapes and sizes. Immediately convinced that he has found a sport he can excel at despite his short stature, he signs up, though Iwashimizu declines. Gion is unable to accept Iwashimizu's excuses and drags him back into the sport. Their training becomes intense as they aim to become the champions of Hanazono, the national high school rugby championships.
