Every Precure you've ever rooted for walks into the same room. The movie doesn't waste time pretending this is anything but a celebration of the entire franchise, stacking fight after fight with the kind of energy that only works when you already know who these characters are. If you've been following this series across shows, this is the payoff: watching teams that never met coordinate their attacks, old villains return just to get demolished, and the sheer momentum of that many magical girls in one story carrying you straight through to the end.
When fairies vanish without warning, Tsubomi and Erika rush to Fairy Park hoping to find answers. What they discover instead is a reunion unlike any other: every Precure across all generations converges on this magical amusement park for what should be a perfect day together. But the celebration turns urgent when a sinister force emerges from the shadows. Bottom, an ancient entity that has waited a millennium for this moment, arrives to claim the Rainbow Jewel, a legendary gem housing the hopes and dreams of humanity itself. With this stone in the wrong hands, the entire world stands to lose everything. The Precures must put aside their differences and band together across timelines and identities to protect what matters most. What unfolds is a high-stakes clash between overwhelming evil and the collective power of every magical girl who has ever answered the call to fight. The fate of countless worlds rests on their shoulders, and for the first time, no single Precure can save the day alone. Only by standing united can they shield the light that keeps hope alive.
