Magical Girl Celesphonia takes you on an urban fantasy adventure in the sprawling city of Echinomiya. You play as Amane, an ordinary woman whose life is turned upside down when mysterious creatures called monstrums begin snatching young women from the streets. Just as disaster strikes, a sentient book offers her a contract: transform into a magical warrior and stop the invasion. Armed with newfound powers, Amane must juggle her daily life-work, friendships and training-while racing against time to keep the city from falling into darkness.
