Tokyo Ravens

Onmyoudou magic was once a powerful technique used by the Japanese during the second World War in order for them to gain the upper hand and establish their nation as a formidable force. But Japan was quickly defeated after the revered onmyouji Yakou Tsuchimikado caused the "Great Spiritual Disaster," an event which plagues Tokyo to this very day. As a result of this mishap, the Onmyou Agency was established in order to exorcise further spiritual disasters and combat the demons that would make their way into the world. Now, Onmyoudou has become far more modern, simplified, and refined for use in a wide variety of applications such as medicine and technology.
