A apparently young woman called Yurine along with her slave, the Karas (in the Japanese phrase for”Crow”), have maintained order and equilibrium between the overlapped worlds, finally maintaining the demons out of interrupting the lives of people. But, humans have started to neglect and jest in the presence of demons, and no more know the privilege it is to live without any anxiety. Disgusted by this event, an older Karas turns his back to the legislation he’d formerly maintained, and in his human form, called Eko, he generates an army of Mikura, or mechanized demons, to prepare an assault on the human race.A young guy named Otoha inherits the forces of their Karas and takes his position in the side of Yurine, who asserts his spirit called out for her while he lived the life of an individual. They reside on the planet of those demons. It’s currently around Otoha to establish himself as a Karas, and reestablish the equilibrium that Eko threatens to mad.Meanwhile, a police officer called Sagisaka along with his fair fresh recruit, Kure, follow the course of their murders dealt with Eko’s Mikura, in addition to the course of a fictitious Mikura called Nue. The prophecy unfolds from here to some tomb revelation for everybody in town.
