Futari wa Precure: Max Heart 2 - Yukizora no Tomodachi

During a skiing vacation, Hikari finds an egg from which a strange bird hatches. They call it Hinata because it's always warm. Soon after, two travellers from the Garden of Clouds come looking for the houou (phoenix) which protects their world above the clouds. They're followed however by two icy dark servants who capture Hinata in order to freeze all the worlds' warmth and kindness. Nagisa and Honoka's friendship is put under stress when they are forced to fight each other. Takes place during the second half of Futari Wa Pretty Cure Max Heart, but is otherwise not related to the series' plot.
