Seventeen-year-old Kira Fujikawa has never had it easy. She's bullied by the popular girls in school. Her parents ignore her. And she's also plagued with a secret: She can see yokai, the ghosts and demons that haunt the streets of Kyoto. But things accelerate from bad to worse when she learns that Shuten-doji, the demon king, will rise at the next blood moon to hunt down an ancient relic and bring the world to a catastrophic end. Not exactly skilled...

All Momo wants for her twelfth birthday is an ordinary life, but instead she finds out she is half human, half goddess and must unlock her divine powers to save her mother's life and keep countless evil spirits from escaping Yomi, the land of the dead.
