Ten members of the Kitauji High School concert band fail to pass the stringent examination after auditioning for club member participation in the Kyoto Prefectural Concert Band competition. Despite the fact that they are unable to play with the rest of the wind ensemble, the group—dubbed Team Monaka—is determined to assist their friends in any way they can until the day of the competition. Team Monaka's efforts, from hauling supplies to making monaka-shaped good-luck charms, were vital for the amazing, heartbreaking summer in the concert band's road toward nationals.
