Demiurge (デミウルゴス) is the Floor Guardian of the 7th Floor of the Great Tomb of Nazarick, the Commander of the NPC defenses, and the 2nd in command of the Floor Guardians. He is the creation of Ulbert Alain Odle. In the New World, under the guise of a powerful Demon Emperor known as Jaldabaoth, he led his demon army to and started a battle in the Royal Capital of the Re-Estize Kingdom, and also led the demi-human coalition in an assault on the Roble Holy Kingdom before switching places and giving the Jaldabaoth persona to demon summon. Demiurge is described to be a tall demon with dark skin and nicely combed black hair. Behind the round glasses are eyes so squinted that they are not normally visible. Wearing a British suit with a tie, he is dressed like a gentleman. Behind his back is a silver tail, covered with metal plates and six long spikes at the end. In his humanoid form, Demiurge's eyes lack eyeballs, instead, shining jewels with numerous small cuts take their place. He can use several of his skills to mold and change certain parts of his body into offensive weapons for battle. For instance, he can produce a unique set of wings from behind his back for flight purposes and to launch feathery attacks at his foes. When in his half-demon form, everything about his body becomes frog-like including his newly-monstrous face with a pair of large black leathery wings. Seeing this, Jircniv presumes that Demiurge may perhaps be a mutant or offshoot Toadman, or even a king-type of such race. For those who first met him in the New World at Re-Estize, Demiurge appears to be wearing a mask which silently conceals his face under the moniker Jaldabaoth. On the other hand, there were others from Kalinsha who ended up discovering that he could assume a different form after they felled for his deception. Although it is true that a demon like Demiurge as Jaldabaoth can transform, the one they witness was not really him, but a familiar he conjured forth in his place.
