Story:
The motif of the new anime is “sky,” and the theme is “hero.” The story set in two places with Precure girls: the heavenly realm Skyland and Sorashido, a city surrounded by nature. One day, Skyland’s young Princess El was snatched by a monster of the Underg Empire. Sora Harewataaru, a brave girl who aspires to be a hero, follows the princess into a mysterious hole — and emerges in another world at the city of Sorashido. Sora encounters a second-year junior high school girl named Mashiro Nijigaoka and ends up living with El at Mashiro’s home.
