Futari wa Precure: Max Heart Movie 1

Nagisa, Honoka, and Hikari are summoned to the Garden of Hope, where courageous warriors ask the Precure for help protecting the kingdom's precious Diamond Line. The jewels are essential to a ceremony that renews the land's water, but a Dark Witch intends to steal them for a far more sinister purpose.

If the witch succeeds, she can revive the Dark Lord and endanger not only the Garden of Hope, but other worlds as well. Far from home and surrounded by new allies, Cure Black, Cure White, and Shiny Luminous must defend the jewels and stop darkness from spreading across the connected kingdoms.
