This is a dance concert disguised as a Precure movie. The magical girls stop fighting and just perform, their animation moving with actual choreography instead of combat logic. If you've ever wanted to watch your favorite characters in a space designed entirely around them having fun together, this is that movie. The music isn't background; it's the entire point. You're not watching a story. You're watching a celebration that happens to star the people you already love.
A shooting star glowing pink falls through the dark sky and hits a Melody Cure Doll displayed in a toy shop. The doll comes to life, escapes her packaging, and starts wandering around the store by herself. Hearing the noise of a crowd outside, she heads out and discovers a huge screen that shows a lifelike image of her, and she begins playing with it. A doll made in Rhythm's likeness soon joins her, and together they spot Humy waiting on a dance floor several levels below. Humy sends up two rainbow keyboards, and the pair slide down them to reach her, kicking off a full concert built around the Pretty Cures from Max Heart through Suite Pretty Cure. Presented entirely in stereoscopic 3D and running about ten minutes, the production strings together a medley of songs pulled from the DX movie series alongside fresh tracks. It plays less like a story and more like a stage show, a bright, music-driven celebration built for fans who want to see their favorite Cures dance together on one screen.
