This is a series of character icon designs based on Japan's Onmyoji culture. In the Heian period of Japan, demons, which should have remained in the underworld, appeared in the human world, causing various disturbances and wreaking havoc. Among the people, there existed a group known as "Onmyoji," gifted individuals who could cast spells, control demons, and summon them as "Shikigami" to serve at their command.
