It is thought to be some sort of kami, represented by a small ghost.[1] The belief of shikigami originates from Onmyōdō. According to the tradition of Onmyōdō, shikigami is a symbol of onmyoji's power because onmyoji can freely use shikigami with magical powers. It has been associated with ”curses” since the 1000s of the Heian period, and was often depicted as a bird or a child in Japanese literature and Emakimono.[2]
