Demiurge


 * "The Seventh Floor Guardian Demiurge, at your command."
 * - Demiurge's Introduction

Demiurge (デミウルゴス) is a floor guardian of the seventh floor of the Great Tomb of Nazarick and the Commander of the NPC Defenses. He was created by Ulbert Alain Odle.

Appearance
About 1.8m tall, Demiurge is a demon with dark skin, and nicely combed black hair. Behind the round glasses are eyes so squinted that they aren't 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.

Demiurge's pair of eyes lacked eyeballs. In fact it was completely without pupil or iris, but were shining jewels with numerous small cuts.

Personality
As a member of the Demon race, Demiurge is one of the cruelest members in Nazarick, taking great joy in the suffering of other races. He enthusiastically performs magic experiments on the prisoners sent to him, viewing them as nothing but toys, and enjoys inciting hateful feelings and treacherous thoughts among them. Being the Commander of the NPC Defenses, he has a high level of intelligence and strategic thinking.

Demiurge works closely with the other servants of Nazarick and is loyal to the creators, thinking of them as important companions. However, due to their conflicting personalities, he and Sebas Tian do not appear to get along well with each other. Though he is a sadistic demon that thrives on the pain of other creatures, he has a more artistic side. He is a skilled carpenter and artisan, with hobbies of crafting beautiful works of art using his victims as his tools.

Background
Demiurge was created by Ulbert Alain Odle.

The Undead King Arc
When Momonga calls for the floor guardians to the sixth floor, Demiurge was the last one to arrive. After paying his respects to the Supreme Being, he ponders about the future of Nazarick. More so, wondering if whether or not Momonga will leave a successor to carry the throne.

While waiting for Albedo on the first floor, Demiurge discovers Momonga attempting to sneak out of the tomb in a dark warrior outfit. Persuading him to take one person along, he accompanies his master as they appreciate the world around them. When Momonga jokes about conquering the world, Demiurge seriously offers to ready the armies of Nazarick to present it as a gift.

After Momonga announces his goals to the NPCs, Albedo has Demiurge relay the words Momonga imparted to him earlier. Misunderstanding Momonga's true intentions, he tells everyone present that their master's wish is to claim the world for the glory of Nazarick.

The Emissary of the King Arc
Upon receiving the messenger from Ainz who relays the question on what Demiurge desires. The demon humble stated that serving the will of his master to be fulfillment enough and questions whether this is a test. He then decides that he would desire to become the marshal of the skies once Ainz's plans for world conquest comes to fruition.

The Dark Warrior Arc
Having been given a mission by Ainz, Demiurge proceeds to find Albedo to announce his departure. Understanding of her nature, he immediately goes to Ainz's bedroom and finds Albedo squirming under the sheets. Listening to her delusions of having Ainz's children, he gives her a tip that the Supreme Beings like boys to wear girls' clothes due to a previous misunderstanding. Exasperated and uneasy, he notifies her of the other guardians' absence and the human experiments being conducted on the Sunlight Scripture before leaving.

The Bloody Valkyrie Arc
Shocked and angry after discovering that Ainz intended to fight Shalltear, Demiurge berates Albedo for letting him go alone. Extremely worried that Nazarick may lose its last master, he tells her and Cocytus that they must bring him back by any means necessary. He declares that he will gather his men to do so, but is stopped by Cocytus, who was ordered to restrain him. Enraged, he tells Albedo that she must resign from her position as Overseer if anything were to happen to Ainz.

When Ainz emerges victorious from his battle, Demiurge and the other floor guardians beg him to never do such a thing again, and to allow them to handle any future incidents that may come.

The Lizard Man Heroes Arc
Demiurge along with the other Floor Guardians threatens and intimidates the Lizardman so that they become part of Nazarick. He uses his magic to forcefully make Shasryu Shasha and Zaryusu Shasha bow down in front of Ainz Ooal Gown.

The Two Leaders Arc
He and the other male Guardians go for a bath together. However, midway through, Albedo and Shalltear attempt to get in and are assaulted by the Lion Golems. So Ainz and the male floor guardians prepare to help them, wishing a peaceful bath the next time.

The Men in the Kingdom Arc
When Solution reported Sebas' possible betrayal, Demiurge is the one who suggested that they take caution and have Pandora's Actor masquerade as Ainz in order to test Sebas' loyalty. He is present along with Victim and Cocytus in testing Sebas' loyalty by ordering him to kill Tuare while having Cocytus confirm if he's delivering a killing blow. After that, he had a bit of quarrel with Sebas concerning Tuare's fate, which made Ainz remembered about Touch Me and Ulbert's quarrels in the past. Also, Demiurge, with Ainz' approval, went to investigate a strange information he found on Sebas' report (Possibly concerning the Golden Princess).

When Tuare is kidnapped, Demiurge brought Entoma, Mare, and Shalltear along with his Evil Lords to punish the Eight Fingers and to initiate Operation Gehenna, where he was appointed the commander. At this time, he told all Nazarick forces gathered in the capital to spare a one human (Possibly Climb) and sent Nazarick's forces to attack several locations, including a new location added at the last minute.

Demiurge, as Jaldabaoth, also saved Entoma before she was killed by Evileye, Gagaran and Tia. Using Evileye as the standard for measuring their group's strength, he launched an attack that immediately killed both Gagaran and Tia. Before he finished Evileye, Momon stepped in and confronted him and later retreated after giving false information to Evileye and exchanging several blows with Momon. He then raised a wall of fire, Flames of Gehenna, on the capital's warehouse district, and have his Evil Lords summoned a demon army, kidnapping the citizens and raiding the storehouses.

When he engages Momon again in combat, they arrived at a location that was prepared beforehand where they put aside their charade and discuss Demiurge's plan, that is to attack Eight Fingers while covering their tracks using Jaldabaoth as a cover and also to obtain great amount of resources and capture humans and also to raise Momon's fame. He was about to leave an item containing the 10th rank spell, "Armageddon Evil" to serve as Jaldabaoth's purpose of invading the capital, which is created by his creator, Ulbert, Ainz gave him another item, which is the prototype of the previous item made also by Ulbert to serve as the decoy. Then, they continue their battle, with Momon seemingly winning the battle. Jaldabaoth then withdrew his forces and Momon became the Kingdom's national hero.

The Invaders of the Large Tomb Arc
In Nazarick, Ainz gathers all of the custom NPCs and strong servants in the Throne Hall. From the convention, Demiurge emphasizes their final objective: taking over the world and suggests to make Nazarick an independent nation.

The Magic Caster of Destroy Arc
Demiurge, in his imp form, was present in the Throne Hall, during the visit of the Baharuth Empire's delegation. During the negotiation, Ainz charged him to act as Nazarick's ambassador. After the delegation left Nazarick, Ainz and the Floor Guardians held a meeting and listened to Demiurge's insight of how the emperor would betray them.

Quotes

 * (To Momonga): "Both wise in judgments and quick in acting. A flawless being."
 * (About world conquest):"If you wish, I will immediately bring the armies of Nazarick and take this jewel box. Presenting this gift to my beloved Momonga-sama, would be Demiurge’s greatest honor.”
 * (About human experimentation): "First would be the healing magic experiment. If you cut off an arm and cast healing on the wound, the arm that was cut off would disappear. What happens if you let them eat the arm that was cut off and cast healing, would the nutrition disappear? If we repeat this indefinitely, will the one eating starve to death?"
 * (To Albedo about Ainz): "This is still too irrational, naive; a purely emotional judgment. Ainz-sama is the last Supreme Being who remains here. Knowing that he faces a situation where his life may be in peril, it is our responsibility to come up with a plan to remove that danger. Even if we will be blamed afterwards, even if we will have to sacrifice our lives, we ought to step forward and act, right?"
