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...
Abandoned by Raikou, Seimei moves forward to hunt Ashiya Douman down herself. The darkness grows within her as she heads to the Light Palace. At the same time, Raikou seethes with anger, blaming both himself and Seimei for the deaths of the innocent.
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.
