The Precure slip into a storybook world that feels like stepping into the margins of a picture you've been staring at your whole life. Nico guides them through it with the kind of quiet knowing that makes you trust her before you understand why. The movie stops trying to be big and lets itself be small instead, which means the actual moments between the girls and this strange kid matter more than whatever plot is supposed to be happening around them.

The Smile Precure team is carried into a world that exists inside a picture book. There they meet Nico, a mysterious figure who lives in the book's world and acts as their guide through it. The film is a 2012 theatrical entry in the magical girl franchise, and it pairs fantasy adventure with the transforming heroines of the Smile Precure series.
