As Cure Muse seems concerned about the Pretty Cure's new power, Hibiki and the others participate in a flea market. Their stand attracts a lot of attention thanks to Hummy and the Healing Chest. The Minor Trio crash the market and steal the Healing Chest, though as they make their escape, Muse takes it an replaces it with a fake. As the Crescendo Tone talks to Muse, telling her about the day when she can remove her mask, the Trio create a Negatone a girl bought from their stand. As 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, claiming to have found it.
今日はフリーマーケットが開かれることになった。そこに響たちも店を出すことにする。そこにトリオ・ザ・マイナーが現れて、ヒーリングチェストを奪われてしまう。響たちは、早く取り返そうと追いかける。
