Original Chief God

The original Chief God is a divinity and the attributed creator of the Monster Girl Encyclopedia world. The Order maintains that the current Chief God is eternal and all-powerful, and therefore that the present head deity is the original head deity. However, in describing the Mamono Lord's rise to power, the Wandering Scholar reports that, "just as in the case of the mamono lord, a new chief god took over, but she was a goddess who was still very inexperienced."

Nowhere are details given on how frequently the title of "chief god" changes hands, what causes it to change hands, or where former chief gods go. Regardless of the identity of the original Chief God, both Order and monsters agree that they were responsible for the creation of the world and for writing the metaphysical "rules" which the current Mamono Lord is fighting against. Where the two accounts differ is on the origin of monsters: Order sources state that the monsters "emerged from the darkness" contrary to the Chief God's plan, while the Mamono Lord maintains that monsters were part of the world from its inception.
