Niko Andros, otherwise known as Cure Celestial, is a fifteen year old freshman who feels like she’s had enough drama to last one lifetime. She was best friends with Chikara Oshiro, a girl who had an unknown connection to the previous Pretty Cure of Keres. Chikara vanished along with twenty-six other teenagers six months back, when the Pretty Cure had their final battle. As much as it tore Niko and her friends apart, they eventually moved on.
Turns out that final battle wasn’t final at all. Sollari, a solar messenger looking for their partner Lune, comes to Earth to find a Pretty Cure with enough potential to save Lune from the clutches of the denizens of the Outer Limits. Unluckily for Niko, she’s the only one Sollari knows about, due to her connection with Chikara.
Despite her fear, Niko wants to protect Sollari and the world from any more pain, and transforms into Cure Celestial! With the power of courage and the light of hope, a new tale of Pretty Cure is about to begin!
