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...
Someone has placed curses throughout the mansion of Michinaga, Minister of the Left. The police magistrate immediately begins to investigate, taking all onmyouji that are not from the Onmyouryo into custody in order to find the culprit.
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.
