Momo Arashima just wants an ordinary life. But she's about to become legendary . . .

After vanquishing a demon king, saving her mum, and reconnecting with her friend Danny, Momo ought to be living the life she's always wanted. But lately Danny has been ditching her to hang out with mean-girl Ryleigh - and groups of children have begun vanishing without a trace.

So when a whole group from Ryleigh's exclusive birthday party becomes the latest to disappear, Momo and her friends (including Niko the fox) are left to fight a dangerous new enemy from Shinto legend. This time they are up against Tamamo-no-mae - beautiful, bloodthirsty and manipulative, she's the ultimate mean girl of the Kami-verse. To defeat her, Momo must travel to the Sky Kingdom and steal the legendary Mirror of the Sun.

But if she's going to survive monster ambushes, escape giant snakes, and pull off the heist of the millennium, Momo will have to find a way to work with her team (even Ryleigh), and grapple with the growing power that connects her with her storm god grandfather and her greatest foe - Izanami the Destroyer . . .
