Futari wa Precure: Max Heart Movie 2 - Yukizora no Tomodachi

During a winter trip to the mountains, Hikari discovers a mysterious egg that soon hatches into a warm, affectionate chick she names Hinata. The little bird is actually a legendary Houou from the Garden of Clouds, and its appearance draws Nagisa, Honoka, and Hikari into a world above the snowy sky.

The ice warriors Freezen and Frozen are hunting Hinata, hoping to extinguish the Houou and plunge the world into frozen darkness. They exploit growing tension between Nagisa and Honoka and turn the two friends against each other, leaving Hikari to protect Hinata while Cure Black and Cure White fight not only their enemies, but the cold doubt forced into their own hearts.
