This one is built to be seen loud. The Super Miracle Idol Festival on Aiai Island is an excuse for a Precure movie to blow its budget where it counts: the songs, the choreography, the final concert set piece that plays like the theater turned into a venue. Be honest about the middle, though. The time travel detour and the goddess business get tangled, the linework wobbles through the first two acts, and there's a stretch where you're waiting for the next number instead of following the plot. Then the last act snaps into focus, the animation levels up, and Tera, the girl who showed up hating idols, finally gets why anyone stands on a stage at all. Tot the coral fairy is doing the most. Stay through the ending track, it's one of the best things here.

The coral fairy Tot invites Uta and her friends to perform at the Super Miracle Idol Festival, the greatest idol festival in the universe, held on the mysterious Aiai Island. A mysterious monster then appears and throws both the island and the world into crisis, and the group is sent flying back in time. The way through the danger is tied to the island's legendary goddess and to Tera, a puzzling girl they meet there who hates idols. The heroines of Hirogaru Sky! Precure and Wonderful Precure also appear. This magical girl music film promises singing, dancing and a special live show for its audience.
