Demiurge is one of the Floor Guardians of Nazarick in Overlord, serving directly under Ainz Ooal Gown. He is a highly intelligent and deeply loyal demon who is known for his calm demeanor, refined speech, and sinister strategic mind. Demiurge often acts as a planner and administrator, carrying out Ainz’s orders with extreme efficiency. Despite his polite appearance, he is terrifyingly ruthless and frequently interprets Ainz’s intentions in ways that lead to unexpectedly cruel but effective outcomes.
