As Cure Muse seems concerned about the Pretty Cure's new power, Hibiki and the others participate in a flea market. The Minor Trio crash the market and steal the Healing Chest, though as they make their escape, Muse takes it and replaces it with a fake. When the Pretty Cure prepare to defeat it, the girl stands in their way, but they manage to get her to believe in them so they can return her doll to normal. After the battle, Ako returns the Healing Chest to the girls.
