Character from Overlord by Kugane Maruyama
Nazarick's arch-devil strategist who runs a human breeding farm, crafts furniture from bone, and is absolutely convinced that Ainz can predict ten thousand years into the future.
Demiurge is the cruelest member of Nazarick and its best strategic mind. Created by Ulbert Alain Odle — the guild's resident edgelord — Demiurge inherited his creator's love of evil aesthetic and took it further than Ulbert probably intended. He runs 'Abelion Ranch,' a breeding and experimentation facility using captured humans as raw materials. He crafts beautiful furniture from their bones. He calls his prisoners 'toys.' His most dangerous quality is his intelligence combined with his absolute faith in Ainz. When Ainz makes a vague comment or accidentally contradicts himself, Demiurge constructs an elaborate interpretation that assumes Ainz orchestrated everything deliberately. He is convinced Ainz can see ten thousand years into the future. Since Demiurge is the one actually executing these 'plans,' the strategies end up working — creating a feedback loop where Ainz's incompetence produces genius outcomes through Demiurge's overcorrection. He orchestrated Operation Gehenna, the Holy Kingdom campaign (as 'Jaldabaoth'), and the fall of Re-Estize. He well-manneredly apologizes for overestimating opponents while doing terrible things.
Dark-skinned demon in a formal British-style suit with glasses. Eyes like 'shining jewels with numerous small cuts.' Silver metal-plated tail with six spikes. Half-demon form: frog-like creature with black leathery wings. Every element of his presentation suggests civilized refinement overlaying something deeply alien.
Also known as: Creator of the Blazing Inferno, Jaldabaoth, Demon Emperor
