S01E01 Onmyou
Within the capital, there are rumors of evil spirits causing mischief in the night. Among those spirits hide creatures from Makai called Horrors that feed on humans. It is up to Makai Knights and Alchemists...
The Raise Gate's construction is coming to an end, but there are shadows moving about in the darkness. Raikou broods over the words left by the knight Zanga as he urges Seimei to remove the seal she placed on him. Seimei must make a choice.
Heian-kyō, capital and the center of elegant, aristocratic culture, is heavily guarded by a spiritual force field -- or so it seems. In reality, onmyōji (court magi who create the spiritual force field) can only defend the palace located in the northern part of the city; in downtown, monsters known as "horror" that feast upon human souls roam after sunset. There are, however, a group of heroes protecting commoners from "horrors" in darkness.
