Pretty Cure Max Heart 2: Friends of the Snow-Laden Sky

Shortly after the fall of the Wicked King, the Queen of the Garden of Light lost her memory and came to Earth, in the form of a 12-year-old girl named Hikari Kujou. Now, she—with the help of Nagisa and Honoka, endowed with new costumes and powers—must find the 12 Heartiels, which hold the key to restoring the Queen's lost memories. For together once again, they are Pretty Cure.
