Kanata, a member of the Takanozaki cheerleading team, is unable to perform after an accident during a competition. One morning, she encounters a girl named Suzuha, who is leaping across rooftops and walls.

Kanata and the others decide to film a support video for Anna and Stout Records. They dedicate themselves to cheerleading practice in preparation for the carnival, scheduled on the store's closing day.

The PoMPoMs, who started their Cheer Delivery service, receive a request from Banka Rara, the captain of the Omaebashi High School Cheer Committee. The request is to help support the baseball team, which has made it to the quarterfinals of the prefectural tournament.
