Demiurge

The Floor Guardian of the Seventh Floor of Nazarick, "Lava."

A demon who takes pleasure in deceiving humans with cunning words and leading them to ruin. He is calm and collected, with a very polite manner of speaking. He possesses the highest intellect in Nazarick and is involved in various strategies carried out by Nazarick.

He took seriously the offhand remark made by Momonga about world domination, setting the grand strategy for Nazarick. Like the other NPCs of Nazarick, he believes that his master, Ainz, possesses unparalleled cunning, and as a result, the ordinary Ainz is constantly forced to pretend to meet their expectations.

He wears a three-piece suit, has black hair slicked back, and an intellectual appearance with round glasses that adorn his Asian features, with jewel-like eyes peeking through the lenses. Additionally, he has six spiked tails covered in silver plate mail. He also has multiple forms, one of which is a semi-demon form where he grows membranous wings and his face changes to resemble a frog.

He upholds Nazarick supremacy and is kind to his kin without exception as a member of Nazarick. However, he only sees humans as amusing toys or useful livestock, often clashing with Sebas on this point. He keeps a large number of humans, whom he calls "sheep," on a ranch and skins them for "parchment" used in scrolls.

Despite his secretive nature and seemingly ulterior motives, his loyalty to Ainz is among the strongest of the Guardians.

Jaldabaoth

A great demon wearing a mask. His true identity is Demiurge, disguised as a "formidable enemy" to quickly elevate the fame of Momon, Ainz's adventurer persona. He also operates behind the scenes as the executor of Ainz's world domination plan. To the Roble Holy Kingdom, he is known as the "Demon Emperor Jaldabaoth."
