"Where does this feeling of wanting to cheer for others come from?" Takanosaki High School is a prestigious school that is preparing to defend its title in the national cheerleading competition. Kanata Misora from the cheerleading club won the national championship in junior high school and became a regular player in her first year of high school, but she can no longer jump because of a mistake in the competition. And one day, Kanata saw a high school girl, Suzuha Kouchi, who was doing parkour and leaping between buildings at high speed. In addition to the two of them, there is also the rhythmic gymnastics lady Shion; the mixed-race girl Anna who returned from Brazil; Anna's classmate, the yoga philosophy girl Unka; and Kanata's former teammate, the girl in a wheelchair, Hui Shen. The members, who have different interests, specialties, and even personalities, sometimes sing together, sometimes clash, sometimes perform skits, and sometimes daydream... And when the pure idea of wanting to cheer for others resonates, the cheering of "flower ball bang bang" will go beyond the scope of cheerleading and directly reach people's hearts. The cheering of the six high school girls in Gunma, maybe it can change the world?
