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.
