History[edit | edit source]
Alongside with the Brotherhood of a Thousand Nights, the Order of the Imperial Demons is one of the two most powerful magical syndicates in all of Japan. For many years the two had fought to control the reins of power in the country. However, when the Brotherhood of a Thousand Nights gain the support and cooperation of the United States after World War II, they ultimately best the Order of the Imperial Demons, thus becoming the dominant syndicate in Japan. The Hīragi clan, in their panic and desperation to overtake the Thousand Nights as the leading magical syndicate in the country, began to pursue and study forbidden arts and magic.
The Order of the Imperial Demons would later be reborn and renamed as the Japanese Imperial Demon Army under Kureto's guidance, and each survivor would become a soldier fighting to save the world from vampires and the Horsemen of the Apocalypse.
