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 to his own pleasure. In a way, Demiurge takes pleasure in 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. He would also act apologetic towards his master on the behalf of the incompetent Floor Guardians barring Albedo for not being able to clearly understand a portion of Ainz's schemes but himself and the Overseer. He is keenly analytical on whatever plans Ainz had in mind for him to do along with the other NPCs, quickly deducing why his master intentionally allows Cocytus to borrow forces of low-tier undead rather than stronger ones.

Demiurge works closely with the other servants of Nazarick and is loyal to the creators, thinking of them as important companions and consider their words/saying as wisdom pass down to him to reflect on. 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 emphasized when Demiurge became the mouthpiece of Ainz to explain their master's supposed plan to his fellow Nazarick denizens. The only time Demiurge was ever known to lose his composure happens to be when his master Ainz's life is in danger. Nonetheless, Demiurge is considerate and meticulous of his plans by not recklessly relying on Nazarick's resources too much. He likes to hear his master Ainz's words directly face-to-face from him rather than through a [Message] call.

On the other hand, Demiurge's kindness is genuine when directed only to his fellow denizens of Nazarick. He is considered to be a very gentle person around the friends in Nazarick he talked to. However, to everyone else who are not align to Nazarick, his fake kindness is falsely the care he gives them like his tools that he treated badly during his experiments. Demiurge would cheerfully talk about his fun 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.

Background
Demiurge was made and came into being by his creator Ulbert Alain Odle. He is one of the Floor Guardians that was assigned to the Great Tomb of Nazarick. In the New World, Demiurge can be seen as 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 also go as far as to set up secret meetings and work with his loyal conspirators within nations who could secretly serve to assist Nazarick's cause in the field of politics.

Among the people he is in cahoot with as his associates, some of which happens to be none other than the Golden Princess from the Re-Estize Kingdom and the current ruler of the Roble Holy Kingdom. Particularly, he has even calculatingly and deviously goes as far as to manipulate nobles like Marques Raeven that hailed from the Re-Estize Kingdom to do his bidding through means of blackmailing him by holding his son hostage. Among one of such other methods Demiurge was recently known to use happens to be a political assassination instigated on Prince Caspond of the Holy Kingdom and replacing him with a puppet to take over the individual's role in the human nation.

From the nations he infiltrated, he made sure to carefully cover his tracks so that various operations started by him don't get exposed to the enemy. In the case of Operation Gehenna which Demiurge had set up, he use the Re-Estize Kingdom as a basis for his grand scheme of things. To Demiurge, it is all so that he can prep his next move, using the Demonic Disturbance he had caused in the Re-Estize Kingdom's Royal Capital as a proving ground for his inevitable course of actions in the Holy Kingdom. Demiurge made the inhabitants of the New World come to believe that he is the rising Demon King, Jaldabaoth. His Jaldabaoth persona that represent the demon's existence came into question when two nations fought him under unique forms respectively.

On the other hand, Demiurge was known to take satisfaction in conducting many experiments. Among all the experiments he oversees doing, Demiurge focuses on testing out interbreeding and healing magic with the people he and members of Nazarick had captured outside the tomb. He refers to his test subjects as the "Abelion Sheep." He has his own farming ranch set up to prepare for skinning them alive in order to grind for materials like their skins to use in making low-tier magic scrolls. Demiurge had several rules arranged to regulate the interactions and hierarchy between test subjects of different races to the extent that he force them to cannibalize each other alive.

While so, he loved craftsmanship in general and had even made use of the bones of his victims to construct things like a chair. Demiurge enjoyed making objects like these. He was very interested in that field, covering items ranging from objects such as furniture kind. It was said that his techniques had surpassed those of a casual dabbler. Through every kind of work he does during duties, Demiurge express the bold desire to impress Ainz and earn his praises by displaying the achievements the demon had accomplished doing.

At some point in the course of the Overlord series, after making himself known as Jaldabaoth in the New World, Demiurge conquered the Abelion Hills and created a Demi-Human Alliance stationed there. In the shadows, he silently led the coalition of demi-human forces into an all-out war with the Roble Holy Kingdom using his summoned Evil Lord Wrath to be Jaldabaoth as a guise to hide his true identity, Demiurge. The tragic events caused by Jaldabaoth in the Re-Estize Kingdom and Holy Kingdom were all orchestrated by him, using such fake persona to also secretly hide Nazarick's involvement and influence in these two nations.

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 a 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, but Demiurge also 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. Demiurge also requested the Death Knight to ask Ainz why he had control of only seven out of the twelve demons while the other five remaining are missing.

The Guardians' Vacation Arc
When Ainz calls for a meeting with the Guardians, Demiurge inquires his master of how can they be of assistance to their liege. Learning that it was about the subject of giving them a vacation, Demiurge informs his master that such matter is handled by himself and Albedo. According to Demiurge, ever since Nazarick was transported to the New World, they have raised their alertness level, and in order to prevent against enemy intrusion, the Guardians like himself remain vigilant 24 hours a day, ready to take on any and all comers. In the end, he had no other choice but to thank and accept his master's care and concern of asking them to rest. However, he suggests Ainz's vacation system requires some time and need to be put to the test first before applying it to every Nazarick denizen except themselves in the tomb.

While spending his time with the Guardians in private, Demiurge express his concern for their master Ainz to them. Demiurge's worry stems from how accurate his prediction was that Ainz would continue throwing himself into work without rest. Demiurge start their discussion off with the first item by leaving it to Sebas to share the result of Ainz's health examination for them to hear. Seeing the bad result, he can't help but feel shock to see that one of the 41 Supreme Beings such as Ainz is supposedly cursed. He informs Aura that the next item they will be talking about is the words of the Supreme Being Herohero. When he learn of "health exam," Demiurge assumes it was used to refer to checking for bad statuses.

On the other hand, Demiurge's conjecture tells him that maybe his master Ainz wanted to give them some to rest solely for the sake of their time to better reflect and improve on what they do. He traced his evidence from the fact that Ainz himself does not bother to rest unlike them. Although he haven't spoken of the time with Ainz since that night in the sky, Ainz felt regretfully bad that he steal Ainz's thunder. Realizing that he was being too hasty, Demiurge believes that in order to gain clearer results, they require more time to think it over for this meeting. When it comes to thinking about the words of the Supreme Beings, Demiurge acknowledge that the most important thing is their effort.

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 inform them the punishment that they must hand down to the Eight Fingers under their master's decree. It was also the time for Demiurge to begin preparing for Operation Gehenna with them. Since it was his plan set up by none but himself, the commander appointed for carrying out this plan in the Re-Estize Capital falls on Demiurge to lead the operation. He was placed in charge of delegating and managing the role of everyone involved in the operation under him. For that reason, Demiurge told those who are present with him the objective of invading each one of the Eight Fingers' facilities that are assigned to them, capturing important people of intelligence as well as taking their valuable resources. During this discussion, he explains the details to everyone involved in his first stage of the operation along with parts of the next phase until the plan begins.

After initiating Operation Gehenna, 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 role-playing combat, the two arrive at a location that was prepared beforehand, where they put aside their charade and discuss Demiurge's plan. One of the objectives Demiurge had committed to do for this operation was to have denizens of Nazarick attack the Eight Fingers' bases and then cover their tracks using Jaldabaoth as a cover who lead the demon forces in the grand scheme of things. While fending off Momon and the adventurers with his armies of demons spread out in the capital, he 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" in one of the Eight Fingers' facilities 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 plans involving the Holy Kingdom. What he understood while carrying out the operation so far was that the ones who brainwashed Shalltear have no connection at all with the Re-Estize Kingdom. Before resuming their role-playing 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 Invaders of the Large Tomb Arc
In the Great Tomb of Nazarick, Ainz gathers together all of the custom NPCs including Demiurge and strong servants in the Throne Hall where Demiurge proudly announce his master's long-term plan for the future to come. From the convention, Demiurge emphasizes their final objective: world domination and suggests that they make Nazarick an independent nation on the global stage. He explains that the actions Nazarick has taken in the Re-Estize Kingdom such as their takeover of Eight Fingers served to be all for that purpose. Demiurge discarded his previous thought of having Nazarick work for a nation, reasoning that their organization will be limited in the actions that they can take. He states that if the people who mind-controlled Shalltear turn out to also be an organization like them, they may not be able to respond promptly if problems arise while Nazarick is beholden to a certain country. Ainz disguised as the adventurer Momon was tasked with infiltrating the Baharuth Empire and secretly meeting with Fluder Paradyne had been part of Demiurge’s plan. Later on, Demiurge took the skin of Arche Eeb Rile Furt after the latter died in the hands of Shalltear.

The Magic Caster of Destroy Arc
Demiurge, in his imp form, is present in the Throne Hall during a visit by the Baharuth Empire's delegation. Seeing that the Empire's delegation have arrived, Demiurge forcefully command them to [Kneel] before Ainz until his master had him release his control. When the delegation offer the head of the noble responsible for sending intruders into the tomb, Demiurge took the urn and knelt down to present it to his master. While the negotiation is going on, Ainz asks him to act as Nazarick's ambassador. After the delegation leaves Nazarick, Ainz and the Floor Guardians hold a meeting while listening to Demiurge's insight as he understood his master's supposed plan better than anyone else in the Throne Room. He carefully explains how the emperor is secretly and silently planning to betray Nazarick behind the scene to form an alliance with other countries against them.

Demiurge believes that Ainz assuming the role of the adventurer Momon was part of his master's plan and how it has become an effective alternative to leveling a country. He reasons that Ainz wishes to take over a human city peacefully, and rule the region with love and compassion. He noted that the Empire deciding to plot a vile conspiracy against Nazarick's rule would go against their master's wishes. He predicts that his master Ainz will show these countries the true meaning of kindness in the near future. He considers his trump card, the Golden Princess Renner as an excellent pawn to include into their master plan. Seeing the Floor Guardian Overseer's interest in meeting the Golden Princess, he promised Albedo that after the Sorcerer Kingdom is established, they will have Renner be an emissary to them in Nazarick.

Meanwhile, Demiurge suggests before they continue on with their plan, an appropriate title fitting for Ainz should be decided upon first. He proposed the idea of calling Ainz, the Wise King to show off and praise his master's exalted intellect. In the end, Demiurge and everyone agreed that Cocytus's idea of "Sorcerer King" is respectfully the best title for their master Ainz. Later, Demiurge planned to have Ainz strike a mighty fatal blow to the other party and let them understand the difference in power between Nazarick's might and their own before they proceed to talks of negotiation thereafter. For that reason, it was Demiurge's intention to make Nazarick participate in the battle between the Kingdom and the Empire to demonstrate their power. When Ainz decides to use and cast the super-tier spell, Iä Shub-Niggurath for this occasion, Demiurge and Albedo can't help but lavish praise on him for doing it.

Before the Massacre at Katze Plains began, Demiurge had requested Ainz to spare three people from being killed in the war between Nazarick, the Empire, and Kingdom. Three of which were specifically happen to be Climb, Ramposa III, and Brain Unglaus so that none of them are targeted by any of the Dark Youngs summoned by his master.

The Ruler of Conspiracy Arc
Planning to obtain permission from his master for the final stages of the plan which requires a doppelgänger, Demiurge returns from the Holy Kingdom and intends to meet up with Ainz about it. Instead, he only find Albedo in his master's office much to his disappointment. However, this feeling was short-lived when he was caught by surprise in learning the news of his master's accomplishment from Albedo where Ainz managed to successfully conquer the Baharuth Empire unlike what he had planned for them. He read the report sent in by Ainz that the Empire has sent a vassalage petition, earlier than expected, offering to become a vassal state to the Sorcerer Kingdom.

In the first place, Demiurge thought that the Empire should only have offered to be their vassals after the Re-Estize Kingdom was destroyed. 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 without problem. 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 deep awe. After realizing his master's accomplishment, he admits to Albedo that there was indeed a way for the Sorcerer Kingdom to vassalize the Empire before they destroy the Re-Estize Kingdom that involves Ainz needing to take action himself.

Subsequently, it convinces and motivates Demiurge himself to work even harder than last time. This affirms his own belief that there are no other Supreme Beings such as his creator Ulbert 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 from the Dwarf Kingdom.

The Craftsman of Dwarf Arc
It was planned by both Demiurge and Ainz where they set up an arranged meeting between the two of them after his master had finished up tasks in the Dwarf Kingdom on the latter's end. 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. From this discussion, he has already drawn up a draft for it about the Empire's vassal status to the Sorcerer Kingdom with the assistance from Albedo. 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 At some point, before or during the war, unclear when or where it happen, Demiurge had Caspond Bessarez assassinated through unknown means. With Caspond mysteriously killed unbeknownst to everyone in the Holy Kingdom, Demiurge had the doppelgänger that was prepared for him by his master Ainz to assume the prince's role in the war as planned.

Under the identity of Jaldabaoth, Demiurge had enslaved eighteen races of various demi-human tribes of the Abelion Hills, forcing them into submission due to his overwhelming power. Due to how powerless they are against Demiurge, the demi-humans can't help but express deep fear and awed by his incomprehensible strength. After he formed a vast coalition aimed at attacking the Roble Holy Kingdom, Demiurge plans to start the war off any moment now by taking into consideration the need to destroy the Great Wall first as the signal.

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, not letting any of the humans from within the fortress of Kalinsha to flee.

At Kalinsha, he infiltrated the city and began a spree of carnage to attract the attention of the paladins located there. When Remedios Custodio, Kelart Custodio and Calca Bessarez assembled before him, Demiurge noted that none were of strength similar to the warrior he fought in the Re-Estize Kingdom, provoking them to not be a threat to him or his plans. Through that brief exchange of words between himself and the three, this explains his reasons for choosing to confront them alone without needing to bring the Demi-Human Alliance to assist him with this fight. Once he finished speaking, Demiurge was attacked from behind by adventurers who use Invisibility magic to sneak up on him. 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 pretended to have been hit a blow from Remedios's strike that knock him away at a random building.

In truth, he purposefully acted that way to retreat back to a nearby house and then switched places with the summoned Evil Lord Wrath to fight in his stead as Jaldabaoth from then on. In other words, Demiurge was no longer going to participate in the fighting against the forces of the Holy Kingdom, leaving the role of Jaldabaoth in the hands of the summoned monster who can take on his mantle. He had Jaldabaoth move accordingly to whatever plans he had lay out in the war against the humans, having the Evil Lord Wrath act as instructed by him. For that reason, Demiurge was still tasked with issuing specific orders out to Jaldabaoth such as having it spare Remedios alive while killing off the other two being her sister Kelart and the Holy Queen Calca. After ordering Jaldabaoth to flee from the battle, Demiurge later had his Evil Lord Wrath hand off the corpse of Kelart to his Circlet Demon and make use of its decapitated head.

Later on, he and Albedo would meet up with their master in a log cabin to hold a discussion about their current objective. When Ainz states that he is planning to implement flaws in his plan, Demiurge was ready to adapt to any situation his master prepared for him. Because Demiurge accepted the idea of faking his master's death, it got him into a heated quarrel with Albedo who was against doing so adamantly. If Ainz dies, Demiurge plans to prepare for his master's resurrection, while also strengthening Nazarick’s defenses and then obtain information on the person who killed Ainz. Since they cannot afford to be careless around someone potentially capable of killing Ainz, he told Albedo that learning the enemy's movements and strengths are vital. He suggests that if the enemy is stronger than they can imagine, the place in which Nazarick resurrect Ainz will become very important.

Furthermore, Demiurge informs Ainz that he had already prepared for an unexpected situation occurs where if the demon was to be struck down, Nazarick will continue to function normally without him. Although this was written only on paper which Ainz had unknowing not read, Demiurge admits he did not bother to put it to the test whether his plan will truly work out. Despite his initial shock of what Ainz had planned for him with his scheme, Demiurge sees it to be crucial for the other subjects of Nazarick to be ready in the event that their master were to die. Resuming the plan, he allows Jaldabaoth and its demon maids to invade the city Loyts where they are set to fight the Sorcerer King Ainz to the death under his master's decree. Along the way, Demiurge had to also help Ainz promote the sale of Runecraft as advertisement for the Sorcerer Kingdom.

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. According to Ainz, the entirety of the Holy Kingdom’s future affairs was now under the control of Demiurge who is overseeing it with the help of his puppet that he gave rise to power in the human nation. Demiurge check on Doppel-Caspond to verify whether the shape-shifter knows his role in this operation, telling him to not forget to incite conflict within the Holy Kingdom while keeping people unhappy as the new Holy King.

Although some things were beyond his expectations, Demiurge can't help but express his sincere gratitude to Ainz with the shape-sifter, stating that the first phase of the plan has concluded successfully and for providing him with an excellent pawn like Neia Baraja. Demiurge describes Neia to have accelerated his long-term plan by cutting some years off it, realizing that Ainz must have intended for him to forcibly drive the girl into the appropriate mental state that she is in now. He orders Doppel-Caspond to support anything Neia does with all his power and authority as the Holy King in order to escalate the conflict between the north and the south. Demiurge informs the shape-sifter that he will soon hand him plans on what to do if someone tries to interfere with Neia while she is on the mission to deify Ainz based on his master's experiment.

On the other hand, he instructs Doppel-Caspond to keep Remedios alive and let her become a scapegoat for the nobles' dissatisfaction in the Holy Kingdom. Demiurge tells the shape-sifter to transfer Remedios to another post and give the Vice-Captain Gustav the position as Captain of the Paladin Order in her place so that they could make meaningful uses out of him. After discussing with Doppel-Caspond, Demiurge had already transition the movement of items including the corpse of the real Caspond back to Nazarick.

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.

Afterwards, he and Albedo accompanies his master Ainz to the Royal Capital where they set off to look for Ro Lente Castle and head there. Upon entering inside the castle, he and Ainz proceeded to enter the throne room where Renner and her father Ramposa III awaits them. He was by Ainz's side as his master sat upon the throne, alongside him, watching Renner deal the killing blow to her father Ramposa that put an end to his life. When Climb arrived at the scene of the murder, Demiurge uses his [Command Mantra] skill to force him to kneel before his master Ainz. Before long, he undo his command over Climb under Ainz's order which set the warrior free to pick up the Razor Edge weapon laying on the ground and raising it at his master. Through the Fall of the Re-Estize Kingdom, it was revealed by Albedo that both Demiurge and herself were able to fully grasp on Renner's capabilities due to how successful their operation have proven to be for them.

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?"
