The leader of Dark Fall has set his sights on the Tree, and it is the Pretty Cure's job to protect it.

In the Splash Star movie, Sirlion, a warrior from Dark Fall, opens up a gateway to the Land of Clocks using directions from Mai.

They both transform using the Mix Commune (ミックス・コミューン, Mikkusu komyūn) through the phrase "Dual Spiritual Power" (デュアル・スピリチュアル・パワー！, Duaru Supirichuaru Pawā!).

Later on in the series, both Saki and Mai transform using the Splash Commune (スプラッシュ・コミューン, Supurasshu komyūn), harnessing the powers of Moop and Fuup.

Throughout the whole series, Pretty Cure's enemies are the villains of Dark Fall (ダークフォール, Dāku Fōru).

In episode 41, Goyan used the Fairy Carafe to bring the previously killed villains (except Michiru and Kaoru) back to life to defeat Pretty Cure.

Marvelous AQL also released several DVDs of the series before later being compiled into two DVD-Box sets by Pony Canyon.
