One thousand years ago, a wish was made and a sword of rage and lightning was forged. A weapon powerful enough to seal away the formidable demon Hakaimono. Now he has broken free. Kitsune shapeshifter Yumeko has one task: to take her piece of an ancient and powerful scroll to the Steel Feather temple in order to prevent the summoning of the Harbinger of Change. But she has a new enemy now. The demon Hakaimono, who for centuries was trapped in a cursed sword, has escaped and possessed the boy she thought would protect her. As the paths of Yumeko and the possessed Tatsumi cross once again, the entire empire will be thrown into chaos.
