Kyogokutei

The principal antagonist of the series. Kyogokutei is a being who serves as the superior to the Ongyou as he provides them their targets and even commissioned Momosuke’s death at first to cover their existence until he saw him to be of use to his scheme. Assuming the alias of feudal lord Danjo Kitabayashi, Kyogokutei commits many inhuman acts as part of an overall plan to cover the world in darkness with the Flame Lance cannon. He was ultimately defeated by the Ongyou devoured by the very darkness of everyone who he used and killed.
