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.

The quiet and unsociable Suzuha secretly admired Shion, whom she met at the entrance ceremony. While following her admired Shion around, Suzuha overheard Shion's singing...

After the baseball support was broadcast on the news, the PoMPoMs received a flood of requests for support. The PoMPoMs sincerely tackle each request one by one, steadily making progress. However, overwhelmed by the sheer number of requests, everyone begins to feel exhausted.

The PoMPoMs are going through a crisis. Megumi confides in Shion and Nodoka and then has the opportunity to have a conversation with Kanata.

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