Oni Lord

Jigoku is not simply a place. It is the manifestation of what the Celestial Order abhors, a state of pure evil that exists for no other reason than to undo Ningen-do. As such, it has created self-aware entities to carry out its desires and plans, somewhat in the same way the Heavens gave birth to the Elemental Dragons.

The Oni Lords are eternal as long as a Jigoku exists to give them power. They may gain a foothold in the land of mortals, but that link is vulnerable, as powerful as it is. In order to step into Ningen-do, the must be summoned by mortals willing to grant their names to oni, amd Jigoku itself must deem it neccessary for them to take physidcal presence in the world. Though it is rare for an Oni Lord's physical manifestation to be destroyed, it is not unprecedented, and such a waste of resources is not taken lightly by the forces of darkness. After suhc an event, an Oni Lord would have to remain in Jigoku in order to lick its wounds and gather strength once again.

Unlike the Elemental Dragons, the Oni Lords do not have a connection to Oracles, instead furthuring their own (usually divergent) goals of their spawn. Currently, Yakamo no Oni and the Maw are uncapable of creating spawn.
