Demiurge


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

Demiurge (デミウルゴス) is the Floor Guardian of the 7th Floor of the Great Tomb of Nazarick and the Commander of the NPC defenses. He is the creation of Ulbert Alain Odle.

In the New World, under the guise known as Jaldabaoth, a powerful Demon Emperor, 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.

Appearance
About 1.8 meters tall, Demiurge is a 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.

When in his humanoid form, Demiurge's pair of eyes lack eyeballs, in fact, shining jewels with numerous small cuts take the place of his eyeballs.

Personality
Since he is a demon, Demiurge is considered to be one of the cruelest members in Nazarick, taking great joy in the suffering of other races. For that reason, he enthusiastically performs magic experiments on the prisoners sent to him, viewing them as nothing less than toys for his own amusement. In other words, he passionately enjoys inciting hateful feelings and treacherous thoughts among the victims of his experiments. In a way, Demiurge takes pleasure seeing the chaos and pandemonium he had incited within the hearts of his subject. It came to a point where he had finally earn the hate by all his subjects of different races much to his delight. As the Commander of the NPC defenses, he has a high level of intelligence and strategic thinking.

When he is around his fellow Nazarick denizens, Demiurge would cheerfully talk about his hobby of torturing his opposition. If he were the one holding someone captive, Demiurge would surely toss the head of his hostage at anyone stupid enough to walk to their deaths. According to Sebas, Demiurge would abuse the hostage in front of the enemy in order to frighten them into submission. Demiurge felt the thought of immobilizing would-be rescuers and then having them watch as he tortured their hostage is a moving sight for him to do. If it were Demiurge, he would even let the rescuers who came to mount a rescue escape with their hostage. Demiurge detailed that he would firstly let them rest at ease and believe they had escaped, and then he would turn the tables on them. This way, he can see his victims experience hope, before having them fall into despair when everything they do works against their favor.

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 shared with their respective creators, he and Sebas Tian do not appear to get along well with each other. Though Demiurge is a sadistic demon that thrives on the pain of other creatures, he has a more artistic side to him. He is a skilled carpenter and artisan, with hobbies of crafting beautiful works of art. Such artwork is done by using victims from his experiments as tools for his inspiration. Demiurge is ambitious about the future of Nazarick and will do everything he can including his duties and experiments like the making of scrolls to strengthen their fighting force. He takes every word his master says literally, misinterpreting them to the best of his knowledge and ability. This can be heavily emphasize when Demiurge became the mouthpiece of Ainz to explain their master's supposed plan to his fellow Nazarick denizens.

On the other hand, his kindness is genuine when directed to his fellow denizens of Nazarick. He is considered to be a very gentle person when it comes to conversing with his friends. However, to everyone else, his kindness is merely the care he gives to his tools. The only time Demiurge was ever known to lose his composure happens to be when his master Ainz's life is in danger. While under the alias Jaldabaoth, he made sure to carefully cover his tracks so that various operations started by him don't get exposed to the enemy. Demiurge is also a secret collaborator with very important individuals from different nations he holds connections to, conspiring alongside them to help further the interests of Nazarick. Behind the scene and war, Demiurge would calculatingly go as far as to set up loyal puppets within nations who could indirectly serve Nazarick's cause in the field of politics.

Background
Demiurge was created by Ulbert Alain Odle and is one of the Floor Guardians of the Great Tomb of Nazarick.

The Undead King Arc
When Momonga calls for the Floor Guardians to meet on the 6th Floor of the Amphitheater, Demiurge is the last one among them to arrive. Seeing that the two remaining Floor Guardians are not around, Demiurge asked Momonga about why Victim and Gargantua are not present in this meeting, to which the latter states that they are only to be moved under special circumstances. He pays his respects to the Supreme Being, describing the greatness of Momonga and his tremendous wisdom to make reasonable decisions and acts on them quickly. As Nazarick's defense commander, Demiurge along with Albedo were given the order by Momonga to be in-charge of drawing up a more comprehensive system for the tomb. At the same time, Demiurge was commanded to exclude the 8th Floor from Nazarick's management system he and Albedo were assigned to do.

After the meeting concluded and Momonga had left, Demiurge notices that Shalltear has been acting quiet for quite some time now and ask her what's wrong while Albedo and Sebas were discussing. Upon hearing her answer, he can't help but facepalm himself, silently musing that Shalltear's behavior towards their master's aura is part of the vampire's necrophilia fetish. When Albedo refuses to let such lewd action from Shalltear go unnoticed, he and Cocytus simply back off from the matter, choosing to leave the two's quarrel to Aura to handle. If things spiral out of control aggressively between Albedo and Aura, Demiurge told Aura to call on his assistance if that happens. Nonetheless, Demiurge admits he is a bit interested on which one of the two female Floor Guardians Ainz will look to copulate in having a child with as a result.

For that reason, he begins pondering to both Mare and Cocytus about increasing the fighting power of Nazarick and what's in store for the future to come in the tomb. Particularly, he wonders whether or not Momonga will be able to give Nazarick a future successor to carry on his will and inherit the throne if he one day leaves them like his creator and the other Supreme Beings. For Demiurge, having the heir of Nazarick will give him reason to pledge his newfound loyalty to it. Interested in knowing what they can do for the strengthening of Nazarick, Demiurge asked Mare if he is interested in breeding a child much to the latter's surprise. Demiurge was able to convince Mare in helping him find and capture any humanoid including different humans and elves that he can used for his Breeding Experiments. Demiurge promised Mare that he will someday offer him knowledge of how to produce children of his own. However, knowing Momonga, he chooses to refrain Mare from participating in doing Breeding Experiments with him as the latter will be scolded by their master for it. Not only that, Demiurge don't want neither himself nor Mare's action to affect Nazarick as operations of the tomb is perfectly balanced at the moment.

As Demiurge thought of setting up a farm outside Nazarick, he then curiously asked Mare why he is dressed as a girl. Learning that his creator made him dress as a "trap," Demiurge contemplates on whether all boys in Nazarick should be dressed the same way as Mare. He shortly later dismiss it to bring attention including Cocytus and Albedo back to the their duties as Floor Guardians, awaiting orders from the Overseer before heading out to do his job.

While waiting for Albedo on the 1st Floor, Demiurge along with his Evil Lords discovers Momonga attempting to sneak out of the tomb in a dark warrior outfit and without an escort. He is able to persuade Momonga to take at least one person along like himself to go with him. The condition to be allowed to go with Momonga was to temporarily refer to his master by a different alias for the time being together. Before he sets off with Momonga, Demiurge orders his Evil Lord subordinates to remain on standby where they're at and explained to the NPCs like Albedo about why he is not with them. Demiurge also informs Momonga that he has no intention of removing honorifics when saying his name within Nazarick unless the former is on a special mission under his master's order. After setting off with his master and accompanying him, Demiurge transforms into his half-demon form and follows after Ainz. The two admiringly appreciate the view of the world around them as well as observing the earthwork being done by Mare while in the sky. When Momonga jokes about conquering the New World, he seriously offers to ready the armies of Nazarick to present it as a gift for his master.

On the other hand, he also tells Momonga that Nazarick's perimeter security now has an early-warning net constructed to be on the lookout for intruders without the opposition noticing. He parted ways with Momonga temporarily before shortly later returning to his side while bringing Albedo alongside him after informing the Overseer that their master will be outside the tomb with Mare. Seeing that both Mare and Albedo were awarded the Rings of Ainz Ooal Gown, he vows to his master Ainz that he will continue working hard in the future to prove his worth for that item.

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 and conquer the world for the glory of Nazarick.

The Emissary of the King Arc
Demiurge is seen receiving a messenger from Ainz via the latter's Death Knight who relays the question about what he desires from his master. The demon humbly states that serving the will of his master is fulfillment enough and questions whether this is a test given to him. Demiurge then decides that he desires to become the marshal of the skies once Ainz's plans for world conquest comes to fruition.

The Dark Warrior Arc
Under his master's order, Demiurge participated in a discussion with Ainz about contingency plans.

Having been given a mission by Ainz, Demiurge proceeds to find Albedo to announce his departure. While on his way to visit, he can't help but admire the entire 9th Floor of Nazarick during his walk through there. Demiurge greeted Eclair Ecleir Eicler, acknowledging that it is up to the latter and Pestonya on managing the 9th Floor in Sebas Tian's stead while he is away. Learning from Eclair that Albedo is in his master's room, Demiurge recalls the time that he had to convince the Guardian Overseer in letting Ainz travel to E-Rantel which he had succeeded successfully.

Upon entering Ainz's bedroom, he finds the Overseer squirming under their master's sheets and with a Dakimakura much to his utter shock. 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 he heard from them. Exasperated and uneasy, he notifies her of the other Floor Guardians' and some members of the Pleiades' absences in the tomb. Additionally, he explains to Albedo about the human experiments being conducted on the Sunlight Scripture, mocking the human captives of betraying their own master before leaving Nazarick to carry out his duty under Ainz's order.

The Bloody Valkyrie Arc
Shocked and angry after discovering that Ainz intends to fight Shalltear alone, Demiurge berates Albedo for letting him go off on his own. Extremely worried that Nazarick may lose its last master, he tells her and Cocytus that they must bring him back safe by any means necessary as he is now in danger of being possibly killed. Demiurge declares that he will gather his men to do so, but is stopped by Cocytus, who has been ordered to restrain him. Demiurge learns that the 7th Floor he had command over is already lock down by Albedo who have asserted control of all the vassals with permission from Ainz beforehand much to his dismay.

Infuriated, he seeks a logical explanation from Albedo on why she made the decision to not allow anyone from Nazarick including himself come to his master's aid, persistently asking question after question with hostility in his tone. When hearing the reasoning of why Albedo decided to not assist their master, Demiurge felt how irrational and naive it was for her to reach such conclusion on her own. Seeing that his master's one-on-one battle strategy as unusual, Demiurge figures Ainz was deliberately lying to them in order to hide something else which neither he nor Cocytus knew of. He refuses to accept her answers as this was not like Albedo, considering that she had initially wanted to have one of the Floor Guardians like himself follow after Ainz when their master decided to go to E-Rantel.

Although Albedo reasons that he needs to have faith in their master, Demiurge remains doubtful of the odds he can secure a win against Shalltear after learning from Cocytus his master's chance of winning was very low. Enraged at how her decisions were based on feelings, he tells Albedo that she must take responsibility for her actions and resign from her position as Overseer if anything bad is to happen to Ainz. In return, Demiurge promised her that if Ainz returns safely, he will obediently yield to her demand if a similar situation occurs which the former adamantly obliges.

While watching Ainz fight Shalltear, he can't help but feel utterly awestruck by Ainz's masterful planning and performance through the battle calculatingly from beginning to end. Demiurge respectfully finds Ainz's use of the warrior transformation spell to be strategic and tactical in turning the battle against Shalltear around his advantages. Although he was thoroughly convinced that Ainz would defeat Shalltear, Demiurge lacks warrior knowledge and still remains somewhat cautious whether his master can keep the momentum going in his favors without losing it to the latter who can possibly overturn the situation. However, Demiurge was reassured by Cocytus that Shalltear abandoning her defense for offense is going according to Ainz's battle plan.

After Ainz emerges victorious from his battle with Shalltear, Demiurge representing the other Floor Guardians beg him to never do such a thing again and to leave any future incidents that may endangered his master's life to them from now on. If Shalltear was stilled brainwashed by the enemy, Demiurge informs his master that he and the rest of the Floor Guardians have already prepared themselves to deal with her themselves while Ainz watches from the sideline in the Throne Room.

The Show Must Go On!
During a meeting on fringe benefits with Ainz and the Floor Guardians, Demiurge requests a new torture room. After the meeting is abruptly ended due to Albedo's and Shalltear's bickering, he has a private meeting with Ainz on the 1st Floor. He believes that Ainz's institution to implement the fringe benefits system is to gauge the loyalties of each of his subordinates.

Later on, when Albedo engages in a scheme to steal a kiss from Ainz through a theatre play of Romeo and Juliet, Shalltear brings it to his attention. He agrees with her that Albedo selecting herself as the main female lead is unfair and with Ainz's permission, they conduct an audition for the role of Juliet.

In the end, though, Demiurge disqualifies both of them, since they have been caught bribing Aura for her vote. Demiurge's role is to ensure that neither of the two will gain the role no matter what the outcome is, as it will create future conflict if one of them wins the position either way.

The Sealed Evil Tree Arc
Demiurge, alongside the other Floor Guardians, is ordered to fight together against Zy'tl Q'ae and to secure the herb and to complete Ainz's adventurer quest from Pluton Ainzach.

The Lizard Man Heroes Arc
Demiurge is seen working alongside Pulcinella in an undisclosed location skinning hides of living creatures and building the Throne of Bones using the bones he put together to craft. This bone-framed construction Demiurge is trying to complete was a gift to give for his master Ainz. Demiurge also evaluates the progress of the experiments that he left to Pulcinella and Torturers to oversee in his stead. He keenly listens to the NPC's thoughts on how the latter was able to bring true happiness for their test subjects in his experiments. Meanwhile, it was revealed by Entoma Vasilissa Zeta that the Message Scrolls he had made were later given to Cocytus for establishing communication with the commander of his undead army.

Later on, Demiurge is contacted by Cocytus for his assistance on how to make the losing undead army emerge victorious against the lizardmen, to which the latter doubts victory was what his master seeks. He suggested to Cocytus that perhaps their master had intentionally and deliberately assigned him inadequate troops of undead He had also advised Cocytus to reflect very carefully on the objective that Ainz have asked of him to do. For instance, Demiurge believes that his master's objective all along was to encourage Cocytus in requesting from Ainz more reinforcements due to how difficult it is to beat the lizardmen with the low-tier forces he had. He felt Ainz wanted NPCs like himself and Cocytus to improve the way in which they approach matters, but with other objectives in mind as well. Just as he began to realize what Ainz's true objective was, Demiurge decided to refrain himself from helping Cocytus any further than he already did considering Entoma is listening on their conversation. Hence, he hurriedly hang up on Cocytus' [Message] call with an excuse that something urgent had caught his attention and ended their discussion right then and now.

After Cocytus lost his undead army against the lizardmen, Demiurge attended the meeting with the other Floor Guardians about the defeat. Before his master and Albedo arrived, he made sure to introduce Victim to Shalltear, Aura, Mare, and Cocytus of the latter being the 8th Floor Guardian. During this time around, he was given the position of Overseer temporarily to lead his fellow Floor Guardians and their vassals at the forefront to the Throne Room where their master and Albedo awaits them. Upon being lavish with praise by Ainz, Demiurge informs his master that he had already captured an adequate quantity of prisoners to ensure that Nazarick will be guaranteed a stable supply of skins for making low-tier spell scrolls in the future. Demiurge reasoned that this was all primarily due to the healing experiments he had done to the prisoners while skinning them repeatedly with assistance from the Torturers. At the same time, Demiurge explained the results of the experiments in detail to Ainz about what he was able to discover after experimenting on them. He is currently in the phase of harvesting the skins according to age and gender. While so, Demiurge tells Ainz that the prisoners are supposedly a two-legged beast which he coins as Abelion Sheep.

Although he already knew what Ainz wants Cocytus to request the latter to do, Demiurges believes that it was the duty of Cocytus to speak up and tell their master upfront. When Cocytus was unable to convince his master to spare the lizardmen, Demiurge steps in to help him out in the end. He reasonably suggested to his master of why and how the lizardmen can be of use for Nazarick and their rulership experiment. After the meeting was over and Ainz left, he explained to the Floor Guardians that his master had foreseen Cocytus's decision, reasoning that Ainz was expecting an alternative solution, one that can justify sparing the lizardmen for the benefit of Nazarick. Supposedly believing that his master had anticipated Cocytus' investigation of the lizardmen strength after knowing victory may be in doubt, he can't help but be awed by how extraordinary Ainz's talent is as a schemer. Soon after, he, along with the other Floor Guardians, threaten and intimidate the Lizardmen so that they become a part of Nazarick. He uses his magic to forcefully make Shasuryu Shasha and Zaryusu Shasha bow down in front of Ainz Ooal Gown, telling them to not resist. When Ainz is finally ready to listen to them, Demiurge permitted the two to raise their head before his master. Once that was over, Demiurge release his control over them before setting off with his fellow Floor Guardians and Ainz via [Gate].

After taking their leave to the Monument of Ruin, Demiurge presents to Ainz a throne made entirely out of bones as his gift. Rather than sit upon the demon's masterpiece, Ainz chooses to use Shalltear as a seat, making the demon feel unexpectedly impressed by his master's decision to do something like that. He views Shalltear to be the kind of chair which nobody can make, seeing the vampire as a proper seat for a Supreme Being to sit on for her punishment. Later, Demiurge informs Ainz that he still requires more time to tally up relevant data and information on how far the Great Lake had been affected by his master's super-tier spell, [Creation]. When his master ponders why the opposition had not spy on them or Nazarick yet, Demiurge speculates that perhaps it was because their unknown enemy is keeping an eye on them with a World Item which renders him immune to regular surveillance. He believes the opposition might be looking to spread rumors of Momon and Shalltear being in league with each other without evidence and lash out at the adventurer. He thinks the opposition will not want Momon to keep growing his reputation unchecked. As Aura suggested why they not spread the rumors after Momon become famous, Demiurge reasons that it would be a poor move on the opposition's part because everyone will have already see the adventurer in a positive light. He figure now that Momon is deem trustworthy, the people will simply dismiss the rumors as malicious gossip. This further raises the question from Aura why had they not spread the yet as he thought, to which Demiurge believes there are two possible reasons for that.

For the first option, Demiurge contemplates whether the enemy has not completed their investigation into Momon. He reasons that if it turned out that Momon defeated Shalltear in open combat, they would wish to avoid incurring the adventurer's ire, or perhaps they would like to recruit him to their side. On the other hand, there was the second option he had in mind where that if the opposition only ran into Shalltear by chance accidentally, encountering her on the way to another objective, and they were a completely unrelated third party. Seeing that they lack sufficient information on an unseen powerful foe who is hiding, Demiurge recommends his master to seek out a nation for their support, using it as a scapegoat to justify and excuse whichever action Nazarick choose to take. Demiurge explained to his fellow Floor Guardians that if they do end up encountering the hostile enemy, they need to have some kind of leverage to use on them during negotiations. For starters, he suggest they convinced people that the holder of the World Item who used it to brainwash others could count as an alibi. With that discussion over and done with, he quickly fetch Ainz an Infinite Backpack and stood by to spy on whatever the lizardmen were planning. Witnessing the inappropriate behavior Zaryusu and Crusch Lulu, he found it displeasing that they are indulging on mating while Cocytus is planning an attack on them anytime soon. Once Cocytus fulfill both his mission and punishment, Demiurge confirmed to Ainz that the Floor Guardian settled the matter without anyone’s instructions or ideas.

The Two Leaders Arc
According to Sous-chef, Demiurge had in the past conducted an investigation of the Mandrakes at Green Hole on the 6th Floor of Nazarick to check on their situation. On the other hand, he had cooperated with Cocytus on the matter of building superior fish farm constructions for the lizardmen to help in managing their food shortage. He guided the lizardman to make preparations in farming fish fries rather than just breeding already-grown fish.

Additionally, Demiurge was also an advisor to Ainz on matters regarding how to deal with Nfirea Bareare. Although Ainz seeks to build long-term trust with the Nfirea, Demiurge had analyzed the situation and suggested they do something different from his master's suggestion. Despite his advise not being follow through, he concluded that it was better to shackle the alchemist to Nazarick and force him to focus solely on research and development of potions work with a debt of obligation.

At some point, Demiurge received a circular folder containing a secret message from his master who invited him to bath with him together at the Spa Resort Nazarick which he accepted. Demiurge then instructed his servant Pulcinella to act as an envoy to Mare specifically, delivering this folder which only male Floor Guardians like himself are allow to read the content inside.

Demiurge is revealed by Pulcinella to be currently conducting breeding experiments at the moment. During this experiment, Demiurge plans to make himself and his other fellow demons out as sacrifices so as not to make his test subjects hate themselves. Seeing that it would be a shame to let the livestock starve, he roasted up the children of both sides whole and served them up to each other. However, when the test subjects are hungry, Demiurge noticed that the gut may be unable to digest food despite the brain desiring it. Taking this into consideration, Demiurge warned them to eat well. Demiurge had even allow the parents of both sides to bid their children farewell, specially permitting them to say goodbye with a smile.

When he finally return back to Nazarick after doing his duties abroad, Demiurge respectfully greeted Ainz and offer him guidance on what appropriate food is best serve for their human guests. Shortly later, he and the other male Floor Guardians came together and then prepare to set off for a bath together. Seeing Albedo attempting to disrupt Ainz's time, he harshly chastises Albedo that she should probably learn how to rein her emotions in before he proceeded to the men's bath soon after. In the bath, he poke fun at Cocytus's exoskeleton body being always exposed as naked all the times much to the latter's displeasure. Learning from Cocytus that he can bathe in hot water, he recommends Cocytus should have suggested they take a hot bath together to promote circulation. After Demiurge finished rinsing himself off, he headed for the tub. Seeing that Cocytus is using his cold aura, he then decided to advise it to keep a distance away from him so that his hot water remains scalding in the bath. Demiurge tells Cocytus that he is not interested in a cold bath as he views a hot bath to be his interest of enjoyment. However, midway through their discussion during the men's bath, Albedo and Shalltear attempt to get in but are assaulted by the Lion Golems. As a result, Ainz and the male Floor Guardians prepare to help them out while wishing for a peaceful bath the next time they have another one again.

The Dark Hero's Story Arc
During the Floor Guardians' meeting on what to ask Ainz as compensation, the subject of clothing is brought up. Upon hearing this, Demiurge becomes interested in the idea of acquiring some new styles of suits to wear.

Ainz Raises Money Arc
Demiurge is present with his fellow Floor Guardians at a meeting with their master. During the meeting, when Ainz inquires which Floor Guardian made the suggestion of the "Bathing Together" voucher, he immediately suspects it was Albedo. However, Demiurge states that he was actually the one who came up with that idea.

During the second meeting, Demiurge tells Ainz that he has yet to use the gold coins and is instead planning to invest them, unlike the rest of the other Guardians. Demiurge states that he is going to begin his investigation over what sort of traders there are in the vicinity and requests his master that he be given more time if permitted.

During a meeting with Floor Guardians, Sebas, and Narberal, Demiurge insists that there could be a hidden meaning behind why they were given exactly three gold coins. He instantly convinces the rest of the Guardians that Ainz must have wanted them to decipher something by giving them "not two or four, but exactly three golden coins."

When Aura makes fun of Shalltear's amazing analysis over the gold coins, Demiurge follows suit by stating that she may be a Doppelgänger in disguise. Considering this idea, it also makes Demiurge think about a plan that requires installing a doppelgänger-puppet king in the Roble Holy Kingdom.

During another meeting with Ainz, Demiurge presents his master with a statue of Momon riding on top of Hamsuke that he had bought. He later then recognizes the name of this statue, which is called "The Hero Momon and his underling Hamsuke."

Table Game to Understand Humans Arc
At Ainz's request, Demiurge, along with several other Floor Guardians, is asked to play a table game as an exercise to better understand humans.

The Men in the Kingdom Arc
Once Solution reports Sebas' possible betrayal, Demiurge who assumes the worst were to happen to their master, suggests that they take caution and have Pandora's Actor masquerade as Ainz in order to test his loyalty. He is present along with Victim and Cocytus in observing Sebas' loyalty being put to the test while the butler was questioned by Ainz. When the butler arrives, he instructed Sebas from getting any close to their master. Demiurge confirmed to Ainz that he had not received any reports whatsoever from Sebas about Tuareninya Veyron. He and Cocytus directed their murderous intent at both the butler and Tuare until Ainz restrain them to stop.

In addition to that, he was palpably ire by Sebas' hesitation to kill Tuare until the latter finally made the decision to do so. Upon Cocytus confirming Sebas' loyalty and to have Tuare spare, Demiurge states that there are still unknown enemies at large, where they would be best served by not allowing information about themselves to spread. Demiurge feels that killing Tuare outright would be more convenient for Nazarick to avoid word from getting out. Realizing that his suggestion was turn down, he recommends Ainz to send Tuare off to the breeding ranch and have her work there with his subordinates. He also advised Ainz to not use the subjects as ration to supplement Nazarick's provisions due to how poorly the quality of their meats are. Demiurge asked Ainz for approval to allow him to obtain grain in order to feed his test subjects, to which the latter accepted, leaving it to Sebas to purchase and direct them to the former. At this point in the discussion, it was revealed by Ainz that Demiurge have made preparations for creating the Demon King.

Along the way, when Sebas looks to let Tuare join the tomb, Demiurge arguably got into a bit of a quarrel with the butler concerning her fate, doubting whether she can really prepare food worthy of Nazarick standard. Disliking Tuare's ability to make basic dishes like steamed potatoes as Sebas' suggestion, he told the butler that she was better off helping him prepare food in his breeding ranch where making mincemeat is hardly a trivial task. When the quarrel is over, he explains to Nazarick's denizens that they are to welcome the new human resident Tuare into their tomb without malice under Ainz's decree. Also, Demiurge, with Ainz's approval, goes to investigate something strange that Sebas detailed in one of his reports (Possibly concerning the Golden Princess). Besides recruiting Renner into working for Nazarick's cause, he was also able to secure information from her on the Eight Fingers and their facilities. Later on, he eventually returns to Nazarick to handle the grain transportation from Re-Estize to the tomb.

When Tuare is kidnapped, Demiurge brings Sebas Tian, Entoma, Mare, and Shalltear along with his Evil Lords to punish the Eight Fingers. It was also to initiate Operation Gehenna, as the commander appointed for this plan in the Re-Estize Capital while overseeing and managing the roles of these NPCs under him. He explains the details to everyone involved in his first stage of the operation along with parts of the next phase.

After initiating the operation, Demiurge, as Jaldabaoth, also saves Entoma before she is killed by Evileye, Gagaran, and Tia. Using Evileye as the standard for measuring their group's strength, he launches an attack that immediately kills both Gagaran and Tia. Before he finishes off Evileye, Momon steps in and confronts him. He later retreats after giving false information to Evileye and exchanging several blows with Momon. He then raises a wall of fire, Flames of Gehenna, on the capital's warehouse district, and has his Evil Lords summon a demon army, which then proceeds to kidnap citizens and raid the storehouses. When he engages Momon again in combat, they arrive at a location that was prepared beforehand, where they put aside their charade and discuss Demiurge's plan. One of the objectives he had committed to do for this operation was to attack Eight Fingers while covering his tracks using Jaldabaoth as a cover and everyone else who are involved in his grand scheme of things. Behind the scene, while fending off Momon and the adventurers with his armies of demons spread out in the capital, he will allow one of his forces to use that time to loot a great number of resources in the warehouse district. To have the goods transported to Nazarick, he had Shalltear open [Gate] and let Pandora's Actor handle the transportation from there. Along the way, Demiurge made his forces of demons go and capture humans silently while everyone else lay the blame on Jaldabaoth after they noticed their disappearance. This entire plan was so that Demiurge can help Ainz raise the adventurer Momon's fame in the Kingdom by driving Jaldabaoth and the demon armies away from the capital.

All the while, he was about to leave an item containing the 10th tier spell, "Armageddon Evil" to serve as Jaldabaoth's purpose of invading the capital and its warehouse district. However, Ainz gives him another item to replace it, which is the prototype of the previous item to serve as the decoy instead. Demiurge thoughtfully planned out this invasion of Re-Estize up until now as a testing ground to prepare for their future course of actions in the Holy Kingdom. What he understood while carrying out the operation so far was that the ones who brainwashed Shalltear have no connection with the Kingdom. Before resuming the battle, Demiurge was instructed by Ainz to damage the armor Momon wore as proof of the intense exchange of blows between the two. Finally, Demiurge as Jaldabaoth continue his battle with Momon from where they left off while ordering Mare to create an earthquake as the signal. In the end, he intentionally let Momon emerge victorious over him as planned by the two of them. Thereafter, Jaldabaoth then withdraws his forces and Momon becomes the Kingdom's national hero.

The Ruler of Conspiracy Arc
Demiurge returns from the Holy Kingdom and intends to meet up with Ainz, only to find Albedo in his master's office. There, Demiurge learns the news of his master's accomplishment from Albedo that leaves him utterly shocked on the fact that the Empire has sent a petition, earlier than expected, offering to be vassalage to the Sorcerer Kingdom.

The best method that he can devise to make the Empire a vassal state will require the estimated time span of at least a month to complete successfully. However, it only takes his master three days at most with no apparent casualties no less to subjugate the Empire under their rule, which leaves him speechless and in awe.

Subsequently, it motivates him to work even harder and affirms his belief that there are no other Supreme Beings in the guild who could've led them this far, but Ainz alone. He and Albedo are given the task to handle the vassalage process of the Baharuth Empire and the Re-Estize Kingdom as well before Ainz returns.

The Craftsman of Dwarf Arc
Demiurge has reported his preparations and activities from the Holy Kingdom to Ainz in full detail, which the latter praises him for accomplishing. Although Demiurge was thankful for the praise, he could not hope to compare his accomplishments to Ainz's, believing that the undead has done much better unlike him. He recognizes Ainz's feats such as securing a place in the Dwarves’ hearts.

After that topic was done, he discusses the vassalization of the Empire which is proceeding accordingly while Ainz was gone and has also drawn up a draft for it. Demiurge questions Ainz, on how far into the future as he predicted the course of the Sorcerer Kingdom will move forward from here on out. To his shock, Demiurge is left utterly bewildered by Ainz's answer being "ten thousand years" that he didn't consider it to be of that magnitude so far ahead in the near future. He told Ainz that a method of utilizing the undead as laborers around must surely be to encourage the other nations to rely on him instead of viewing their troops as dangerous elements.

Awed by Ainz's ambition, he concluded that this must have been the right answer all along for him to look at the world from such a wide-angle. Demiurge proceeds on to the regards the unknown event will take place during the fall and winter seasons. Despite Ainz's approval, he speculated that the event may not go so smoothly as planned when there might be some discrepancies along the way. Leaving aside the matter over Empire's vassalization for another time, he listens to a request from Ainz on wanting a copy of his plan given to him which he accepted.

Nazarick Mythology Arc
Demiurge attended a meeting to create a mythology of his master in order to solidify his hold over the masses. In his myth story, the world was once dominated by a terrifying demon force and was literally hell on Earth. A savior came in the form of Ainz Oal Gown who defeated the demon army with his magic. The people wished for their savior to lead them but declined as the demons were not completely wiped out. In order to defeat them for good, he sets out to look for greater power and promises to return. Now that Ainz has return Demiurge states that the people will serve Ainz as his livestock. The last part of Demiurge's story stuns Ainz and the rest of his colleagues. Demiurge and Sebas nearly argue, until and Albedo, Shalltear remind them that they should take care that they are in the presence of the Supreme Being.

The Paladin of the Holy Kingdom Arc
and The Paladin of the Holy Kingdom II Arc Under the identity of Jaldabaoth, Demiurge had enslaved eighteen races of various demi-human tribes of the Abelion Hills and formed a vast coalition aimed at attacking the Roble Holy Kingdom.

After stating his intentions at a parley with the human general in command of the Great Wall, he used his magic to summon a meteor that breached the barrier that protected the kingdom. He ordered his demi-human slaves to begin their attack and for his demons to support them.

At Kalinsha, he infiltrated the city and began a spree of carnage to attract the attention of the paladins located there. When Remedios and Calca assembled before him, Demiurge noted that none were of strength similar to the warrior he fought in the Re-Estize Kingdom. Once he finished speaking, he was attacked from behind by adventurers who use Invisibility magic. However, their group assault did not do any harm to him while he, in turn, sprouted a set of strange wings that impaled some of them to death. Later, Remedios join the battle against Demiurge, attacking him alongside the aid of Kelart, Calca, and various angels. During the course of the fight, he retreated back to a nearby house and then switched places with the summoned Evil Lord Wrath to fight in his stead.

Later on, he and Albedo would meet up with their master in a log cabin to hold a discussion about their current objective. Ainz states that he is planning to implement flaws in Demiurge's plan as well as faking his death. Despite his initial shock of Ainz's plan, the demon sees it to be crucial to prepare the other subjects of Nazarick.

Once the war came to an end, Demiurge secretly confronted Doppel-Caspond, discussing with him about future plans regarding the fate of the Holy Kingdom and its countrymen.

The Witch of the Falling Kingdom Arc
According to Albedo, as the operations against the Roble Holy Kingdom drew to an end, she noted how Demiurge has been busy traveling far and wide outside the tomb to set up an intelligence agency with Nazarick/Sorcerer Kingdom at its center. She believes Demiurge is most likely the person who will be assigned as the head of such organization that is being planned out and prepared for by him.

In the Audience Room, Demiurge was present with the other Floor Guardians. There he silently watches as Shalltear bring Hilma Cygnaeus to present his master Ainz a witness who can explain their questions about the attack on the Sorcerer Kingdom's trade caravan of grains. Every Floor Guardian including Demiurge during the meeting approved of the punishment Ainz has suggested for Hilma Cygnaeus to do. Once that matter was concluded, discussion about Philip resumes where it left off while the Overseer explains their strategy for the Fall of the Re-Estize Kingdom.

When Ainz states that he believes Philip did what he did without thinking it through first, Demiurge agreed with his master's opinion, seeing the noble being an idiot which could explain his action. He reasonably affirmed Ainz's idea to Albedo, with support from the elf twins who also agreed with what their master say. As Ainz offers the other Floor Guardians a chance to speak out, Aura and Cocytus each had a question to ask regarding the strategy of their operation and why they have not done it differently during the start to get rid of that nobleman. For Aura, Demiurge reasoned with her on how and why they cannot use any other noblemen out there but Philip alone, explaining the various risks involved if they were to take on such approach.

As for Cocytus, Demiurge reasoned with him on having already recruited someone like that which was blackmailing Marquis Raeven. Not just that nobleman alone, but Demiurge also show his support to Cocytus's way of thinking. He had taken into consideration that sparing an expendable portion of the nobility who were at least somewhat capable, talented or hard-working ascetics should be worthy for Ainz to have rule over. According to Demiurge, this was why they formed a New Faction in the Re-Estize Kingdom which was filled with incompetent people to use as a scapegoat on killing off. He informed Cocytus that they received intel on the talented people of that nation as well as also having collected intel of their own directly from the source.

Next up was Shalltear who believes Philip's attack on their caravan constitutes action from the Sorcerer Kingdom. Demiurge also agrees with her thoughts on it being used as a casus belli to justify their planned invasion of the Re-Estize Kingdom. He inquires others including the former to suggest what punishment they should do in response against that attack from the Re-Estize Kingdom, particularly Philip on their nation.

Agreeing to both Aura and Mare's response of killing Philip, he asks the rest of the Floor Guardians if giving him a death sentence will only end there, which Cocytus refuses as the punishment should extend further to the perpetrator's master.

With everyone's thoughts taken into consideration, Demiurge came to acknowledge Shalltear's judgement on the matter, thinking that more appropriate punishments are in order to be handed out to the entire Re-Estize Kingdom rather than just Philip alone. He retold Ainz's past words to the rest of the Floor Guardians, informing his colleagues that what their master is looking to rule over is not a ruined country and suggested they must avoid creating that kind of situation with the Re-Estize Kingdom. For that reason, Demiurge believes it was best not to punish the whole people of the Kingdom entirely. Rather, he felt the Sorcerer Kingdom needs to make a painful example out of the Re-Estize Kingdom in order to show the surrounding nations to not take them lightly or else they may suffer the same fate.

A month later after the Sorcerer Kingdom's declaration of war against the Re-Estize Kingdom, Demiurge had contributed to the campaign by deftly managing everything so that not a single piece of intel was leaked. This is noted when the Re-Estize Kingdom have not noticed the Sorcerer Kingdom's invasion at all, still thinking that the latter's forces are still holed up in E-Rantel. Because of that, his work was commented by Ainz during a meeting with the Floor Guardians in Nazarick. According to Demiurge, they have fully established surveillance on every street, while having also sent Shadow Demons to scout out the neighboring cities. Demiurge notes that the only thing they need to be wary of outside their surveillance is the hermits and druids who are not part of civilization. As a result, he was given the task by his master to discuss the matter with Albedo, strengthen the surveillance net until those he has mentioned can also be found.

Upon seeing the flying armor giant destroy both the Death Knight and the Death Warrior, Ainz expected Demiurge to have already known the reason of why Ainz did not sent so many forces at the city of E-Naüru. Once Shalltear explains to her colleagues why their master sent in a weak force, Demiurge offers her and Cocytus praise for being able to understand the scope of Ainz's ploy. When Demiurge was asked the question by his master about how to deal with E-Naüru now that Red Drop have join the battle, the former suggested of sending a stronger entity than their enemy adventurer into that port city and destroy it. He felt it would be bad for the enemies to mistake the notion that they have a possible chance in defeating the Sorcerer Kingdom.

Later Demiurge had observed the battle between Pandora's Actor as Ainz Ooal Gown against the mysterious Riku Aganeia via a Mirror of Remote Viewing along with Ainz and Shalltear. Once Pandora's Actor and Albedo returned to Nazarick to deliver their reports he observed the meeting on Riku and his strange abilities. In the discussion of Pandora's Actor's performance, he disliked the idea of the Area Guardian acting cowardly before Riku even if was to get his guard down suggesting it would draw suspicion. On the identity of Riku, and the possibility on whether he was one of the Thirteen Heroes or the Platinum Dragon Lord, Demiurge confessed that the did not have enough information to make a definite conclusion. Plus whether Riku can be converted to their cause would still be up for debate and Ainz agreed to have Demiurge opinion on the matter.

Trivia

 * In the Web Novel, Demiurge is the Overseer of the Floor Guardians instead of Albedo, who doesn't exist. Also, the author Maruyama states that Demiurge can conquer the continent in about 5 years, though he isn’t exactly sure how much damage Nazarick would sustain in the process.
 * The name "Demiurge" is the name of a being responsible for the creation of the universe in. In Gnosticism and other theological systems, a heavenly being, subordinate to the Supreme Being, that is considered to be the controller of the material world and antagonistic to all that is purely spiritual.
 * His assumed name "Jaldabaoth" is the name of a supernatural being considered to be a member of the Demiurges. The name Jaldabaoth means "traitor." It seems that Demiurge selected this name as he needed to fight against Momon with a fake identity.
 * Demiurge believes that all boys in Nazarick should wear skirts, due to a misunderstanding with Mare.
 * Demiurge commands seven custom-made demons named after the Seven Deadly Sins. However, he was supposed to originally possess twelve of them. The names of the missing demons stated by Demiurge are Garira, Iabel, Belias, Kainon, and Abiretsia. Furthermore, when asked which domain Demiurge wishes to govern for himself after the world becomes Ainz's, he asked for the right to administer the sky on his behalf.
 * Among all the people in Nazarick, Ainz and Albedo are the only people that Demiurge cannot read.
 * After Demiurge's debut as Jaldabaoth in Re-Estize, various nations of the New World learn of his existence. However, Demiurge is disappointed that they have labeled him as an Archfiend rather than a Demon Emperor.
 * When Maruyama was asked what would happen if Ulbert gave him the order to kill Momonga, he believed that the current Demiurge would gather all the NPCs in the Throne Room, then challenge Ainz to a head-on fight alone.

Quotes

 * (To Momonga): "A wise leader who makes decisions and acts on them quickly. Truly, a man worthy of the title 'inscrutable'."
 * (To Mare about Momonga and his successor): "Any great leader requires a successor, no? Momonga-sama may have stayed with us until the end, but if he loses interest in us one day, he may leave for another place like the rest of the Supreme Beings. Thus, there is a need for a successor to whom we can pledge our loyalty."
 * (To Momonga 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.”
 * (To Ainz's Death Knight about the 7th Floor): "This land, this dominion was designed and created for me by Ulbert-sama, so it contains everything I need to perform my function. Indeed, it may appear as a mere ruin to you, and the center where we stand may seem like a little more than a barren waste, but many things are hidden within it. These tumbled ruins are the true expression of Ulbert-sama's love."
 * (To Albedo about human experimentation): "First are the healing magic tests. When we cut off an arm and heal the wound with magic, the severed hand disappears. Now, if we had them eat the severed arm and then healed the wound, would the nutrients derived from the arm vanish? If we repeated this over and over again, would the people who ate the arms starve to death?"
 * (To Albedo concerning his experiment on humans): "In addition, we allow them to vote on who should become the others' food, and who should be the one to cut off the food's limbs with a blunt ax. We do so by a registered vote."
 * (To Albedo in regard to the human experiment): "But of course. There will be a hierarchy among the prisoners, from those who will become food and have their limbs chopped off, to those who will chop the limbs off, and those who will eat those limbs. This creates hatred, and once they are gripped by that hatred, all we need to do is gently urge on the ones who were used as food. This encourages them to revolt, and the effects are very obvious. Beings that hate everything are truly fearsome."
 * (To Albedo about Humans): "That is what makes it interesting. You could enjoy the humans in that way too, could you not, Albedo? All you need to do is treat them as toys."
 * (To Albedo about their creators' preference): "Then. I will be off. Right...since you wanted to make boys' clothes, you might want to know this. Did you know that the Supreme Beings seem to prefer boys in girl’s clothing?"
 * (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 afterward, even if we will have to sacrifice our lives, we ought to step forward and act, right?"
 * (To Ainz): "Of course, we are butchering the dead livestock and feeding it to other livestock. Since it would be difficult to eat whole, we grind it up first."
 * (To Ainz): "...No, Ainz-sama's schemes are elaborate and farsighted. I cannot hope to compare. And I believe what I understand is only a portion of your plans."
 * (To the Floor Guardians and other NPCs about Jircniv): "...And so, I think the Emperor will try to put a scheme like that into practice. If he were more foolish, his actions might fall outside the predicted range, but I think the chances of that will be low. Reading the movements of a slightly-above-average intellect that imagines himself a genius is easier than trying to predict the actions of a complete moron."
 * (To the Floor Guardians and other NPCs about Renner): "...Perhaps we could use the Golden Princess to achieve similar effects, but that would be a waste of a trump card. She is a human being who is just as interesting ―no, perhaps even more so― than what I have determined from analysis of Sebas' intelligence reports. She will be an excellent pawn."
 * (To Albedo about Ainz): "I desire to display my achievements to Ainz-sama, so I do not wish to use such methods to contact him. While I can receive his praise through a [Message], in the end, I would still prefer to hear his voice in person. That is all...Is that not the shared dream for all in Nazarick?"
 * (To Albedo): "As, as expected of Ainz-sama. Someone like me could not hope to even approach him. He is truly a peerless and perfect master. Nobody else could have led the Supreme Beings. I cannot help but envy Pandora's Actor, even if just a little."
 * (To Cocytus): "Exactly, you're completely correct, Cocytus. To Ainz-sama, someone who's capable of planning on the scale of millennia and myriad years into the future, something on the scale of a few years is nothing."
