In a world marred by the supernatural, Japan suffers from its own fair share of evil and demonic disasters, with generations of shamans known as Onmyoji protecting their homeland from these forces of evil. Capable of wielding magic and using spirits of their own, these shamans were not only skilled in battle, but also divination.

However, they were unable to correctly predict Japan's loss in World War Two, and suffered the punishments that followed.

Persecuted and torn apart by infighting, the Onmyoji reunited under the banner of the Tsuchimikado clan, descendants of Abe no Seimei, one of the greatest Onmyoji to ever live. The Onmyoji began to rebuild and to regrow.

Ren is the sole heir to the Tsuchimikado family, but has been unable to practice Onmyodo ever since his birth, even though he possesses the greatest ability in the family.

But when disaster befalls his family, Ren has nobody to turn to, and no idea how to use his powers. As he journeys to escape the same fate his family faced and attempts to learn how to use his powers, there is only one question on his mind; as the Tsuchimikado heir, how can he save the Onmyoji... from themselves?

note from author: I'm writing this based loosely on the very real theories of Onmyodo, and so my writing may not be a truthful or accurate depiction of Onmyodo or other related areas, such as religion, for instance. That is why, while depicted in the real world, events that happen may seem unrealistic and it may be easier to imagine it as a parallel universe that is the same as ours, but with slight differences so that my possible errors will be easier to overlook. Sorry, and thanks!
