Plot
Onmyodou magic was a powerful technique which was used by the Japanese during World War I. Later, the infamous Yakou Tsuchimikado performed a ritual known as the "Taizan Fukun Ritual", which will eventually bring out Japan as a formidable force. However, the ritual goes horribly wrong and the result of this becomes what is now known as the "Great Spiritual Disaster", an incident which haunts the entire Japanese continent to date. In addition to this, the Onmyo Agency was established to monitor supernatural activity in the area and to combat any spirits or demons that would make their way into the real world.
