Nagisa and Honoka aren't saving the world anymore, they're raising it. The Queen arrives as a blank slate who needs to learn what it means to be human, and the girls have to teach her while fighting monsters that get stronger every arc. This is PreCure learning that sequels don't need to go bigger; they go deeper, turning a magical girl show into something about chosen family raising a child together.

After the Wicked King falls, the Queen of the Garden of Light loses her memory and comes to Earth as Hikari Kujou, a 12-year-old girl. Nagisa and Honoka receive new costumes and powers and join Hikari to search for the 12 Heartiels, which are the key to bringing back the Queen's lost memories. Reunited, the two once again fight as Pretty Cure. The 47-episode magical girl TV series blends action, adventure, comedy and fantasy.
