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 their fairies Coffret and Shypre slip away, leaving only a note behind, best friends Tsubomi and Erika follow the clue to Fairy Park, an amusement park floating on the sea. There they find a crowd of fairies and the other Precures, all gathered to spend a special day together. The park is home to the Rainbow Jewel, a gem that holds the hopes and dreams of the world. Bottom, a malevolent being who has waited a thousand years to seize it, suddenly appears and throws the park into chaos. Seventeen Precures step forward one after another, uniting to guard the jewel in this second All Stars crossover movie, a mix of magical girl action, comedy and fantasy.
