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.

Summer vacation. The PoMPoMs gather at Emina's house for a video project meeting. Before the meeting, while everyone is relaxing, Suzuha suddenly starts checking the results of her lottery tickets...

The PoMPoMs spend the rest of the summer fulfilling support requests. Kanata is feeling better and is slowly trying to get back into cheerleading.

Mari has disappeared, and Kanata and the others go to look for her. After discovering her problem, they decide to cheer her on.
