A Summer Festival in the Magical World! Fly High, Fireworks!.Magic School's summer festival gets underway, with Jun, Kei, and Emily tasked with making fireworks. However, they discover that the Don-Don Flowers used for making the fireworks have mysteriously wilted. Hearing about a Pachi-Pachi Flower that can be used instead, the girls split into groups to find their whereabouts. With everyone's combined efforts, Mirai's group finds several flowers resembling the Pachi-Pachi Flower inside a cave, but are unsure which is the right one. As the girls pick which they believe are the right flowers, Labut appears and summons a Rabbit Don Yokubal to attack the Cures. Despite being restrained by hoops, the Cures trust in each other's actions and manage to defeat the Don Yokubal. Having made the right choice, the girls launch a fantastic fireworks display together.
