All over the world in the Garden of Light, the Palmier Kingdom, Märchenland, and many more kingdoms, the Pretty Cure protect the peace. Yet dark forces from every corner of the map are sending the world into chaos, and Cures old and new will be called upon to combat these threats. But these threats take many shapes, and not every Cure is ready for battle.

At the same time, bounty hunters are after their heads as retribution for all the pain they've caused. Now more than ever they must decide whether to stay together or go their separate ways.
