Sora Kurumatani, who is fat, weak, and very passionate, goes to Kuzuryuu High School in the hopes that he will fulfill his mother's wish by winning his first high school tournament. Even though it's been turned into a haven for lawbreakers, the local basketball club doesn't actually play any games! Both Momoharu Hanazono, a talented blocker who can perform power jumps but is terrible at shooting, and his twin brother Chiaki, a gifted point guard, have abandoned their respective vocations in the sport as a result of their lack of interest. With just one game full of adrenaline and excitement and Sora's pure love for the game, the youth's dying love for basketball is rekindled.
