 * — Aura's Introduction
 * — Aura's Introduction

Aura Bella Fiora (アウラ・ベラ・フィオーラ) is a dark elf and one of the twin Floor Guardians on the 6th Floor in the Great Tomb of Nazarick. She is the twin sister of Mare Bello Fiore and was created by Bukubukuchagama. As a beast tamer and ranger, she is capable of controlling magic beasts and is a master of guerrilla warfare.

Appearance
Aura is a tomboyish looking child with dark skin and pointed ears, a signature trait of the dark elves. She has golden hair and heterochromia, her left eye blue and right eye green. She wears reddish-black dragon scale leather covered by a white and gold vest embroidered with the sigil of Ainz Ooal Gown.

Below it, she has a matching set of white trousers and gold plated shoes, and around her neck is an acorn necklace emitting golden light. She is equipped with a whip around her waist and a giant, decorated bow on her back. In addition, she wears a watch given to her by Ainz, which has her creator's voice recorded on it.

Personality
Unlike her brother Mare, Aura is a very cheerful, tomboyish girl who is often straightforward and blunt with her remarks. She dominates over her brother, often dragging him around and telling him what to do. At first glance, she does not appear to get along with Shalltear and will usually get into small quarrels with her, but in reality, the two of them are quite close as if they are true sisters. She also inherits this from her creator.

Aura also has a collector's spirit when dealing with creatures. In the New World, she wishes to add any new unfamiliar creature she finds into her collection of beasts. However, Aura's behavior and actions when talking about Kyouhukou's cockroaches, and later, when Ainz orders her to deliver Hekkeran and Imina to Gashokukochuuou, shows that she has a fear of insects and other such creatures, which is unusual, given her role as a beast tamer.

Like all NPCs of Nazarick, Aura is completely loyal to Ainz and will sacrifice everything for his sake. She carries out her duties with great zeal and will give up on her own interests if she is ordered to. She misses her creator Bukubukuchagama dearly and enjoys hearing her voice from Ainz's watch. However, she can be outspoken about Ainz's perverse action. According to Maruyama, since Aura inherit some of the heart of Bukubukuchagama, Aura was the kind who would act in the same manner as her creator who might speak up to the little brother’s friend.

Background
Aura was created by Bukubukuchagama, and much of her personality is based upon her creator's circumstances in real life. Her dominance over Mare is most likely stemmed from her creator Bukubukuchagama's belief that younger brothers should listen to and obey their older sisters.

Whenever they had to visit the other Floor Guardians for fun or do other things, Aura and her brother would always tell each other where they were headed. That was because the two were assigned to guard their Floor together by order of the Supreme Beings.

As Aura tends to go patrol the forest in the meantime, it was Mare's duty to watch over the Amphitheater for the time being. If her brother intends to leave the location, Aura is the primary person Mare needs to inform about his reason for leaving.

The Undead King Arc
After Momonga teleports to the 6th Floor, Aura takes notice of his presence and jumps down from the Colosseum to greet her master respectfully. She then calls for her brother Mare to also pay his respects, but when he takes too long, she gets angry and begins reprimanding him. Momonga is not bothered by Mare's actions at all, telling Aura to forgive her brother and forget scolding him. Aura admits that she felt bore because there hadn't been any intruders lately to fight against. She had trouble finding someone who can keep sparring with her for more than five minutes. When her master suggested that there is Mare who is worthy of her time to fight with, she sighs and unintentionally activated her skill that caught Ainz's attention. It was to this point that Aura immediately apologizes to her master upon noticing what she had just done and canceled her skill shortly thereafter. Although she knows his undead status was what prevents him from being affected by her mind-affecting skill, she felt it would be rude top have the effect be noticed by her master, hence the deactivation. She informs her master Ainz that he was within her skill's effective radius. When her master said that her skill should not have an effect on people from the same group or guild, she shows concern whether Ainz got it mixed up with the ability to freely change the range of one’s skills.

Wondering why Momonga has come to her floor in the first place, Aura was shocked to hear from her master that he is on her floor to do some training and perform various experiments with his magic and staff. Under Ainz's order, she was given the task of using other effects from her skills which she did on the Moonlight Wolves summoned forth by him using the Staff of Ainz Ooal Gown much to her confusion and his curiosity. She was allowed to use her skill on these creatures along with her master within its radius. Responding to his next experiment appropriately, Aura has her servants bring a scarecrow for him to test his magic on. When Momonga asks if she wants to fight his summoned primal fire elemental, she agrees to do it and waits for him to summon the entity. During the summoning of the elemental, she and her brother was being protected and shielded by her own servants, the Dragonkins from its fire effect that was unleashed along the way. After her master summoned it and letting her do whatever she wants with it, she enthusiastically charges in while dragging Mare with her so that they can fight together side by side. When she and her brother finally defeated the elemental, she returns to Momonga's side and thanking him for giving her an opponent who can make her work her hardest to beat. Feeling tiresome and sweating after the battle, she and his brother were given a drink of water by Ainz to help the two energize. After witnessing the generosity and kindness from Ainz, Aura can't help but whisper that perhaps her master was not as scary as she thought he would be. Aura wonders if she and her brother were the only two who her master is nice to much to her delight while he patted her lightly on the head.

At the same time, the Floor Guardian to arrive before everyone else except she and Mare was Shalltear who later got into an argument with her. Aura would spat out several kinds of insults at the vampire including her fake chest, successfully provoking the latter to become anger by the former's harsh words. Before long, Cocytus arrives and Momonga decided to order both Aura and Shalltear from continuing this verbal exchange any longer. Once every other Floor Guardians after Shalltear finally arrive at the Amphitheater, Aura later joins them in a formal salutation toward Momonga. Together, they collectively pay their respects and admire the powerful presence their master has. She along with her brother Mare are given the order by Ainz to work together on camouflaging the Great Tomb of Nazarick using their own means or anything else they can find from other floors. After the meeting was over and Momonga left, she share the same sentiment as Mare, thinking that her master's Despair Aura emanated by him was squashing her flat. Nonetheless, Aura inform her fellow Floor Guardians that she believes Ainz was a benevolent master around herself and Mare, stating how he was kind enough to offer the two a drink of water that made her colleagues jealous towards them. When Albedo started a heated argument with Shalltear, Aura was suggested by Demiurge as she is a fellow woman like them, it is her job to settle and resolve their dispute peacefully.

The Emissary of the King Arc
Aura spots a Death Knight approaching the Gigantic Tree and realizes it is a messenger of Ainz. She allows him entry into the tree, giving it a Minimum ring, allowing it to shrink and enter. The dark elf girl calls Mare to get out of bed, while she gives the undead a tour of the tree. Once Mare arrives and greets the Death Knight, they sit down to listen to Ainz's relayed questions. Upon hearing the undead's questions from their master, Aura sees that her brother is confused, but nonetheless believes Ainz has a reason. On their interpersonal relationships, Aura states she has her brother, animals, and female Floor Guardians as company. She answers for Mare, stating that he is a bookworm and hardly goes out. She berates him to make friends, to which Mare meekly agrees. He is recommended by Aura to start with the librarian, Titus Annaeus Secundus, since they have similar interests. On the topic of their desires, Mare wants some plant monsters to raise to protect the floor, as opposed to Aura wanting a new magical beast that can fly.

The Guardians' Vacation Arc
When Ainz calls for a meeting, Aura figures it was about an enemy attack on the tomb. However, upon learning that his master orders them to have a vacation, Aura tells her master that she is fine and doesn't need to rest much to the latter's insistence that the former obeys. Hearing his reason that she is require to have enough rest and nutrition while growing up, this encourages Aura to make harsh remarks indirectly at Shalltear. She provoke Shalltear further, stating that a hundred years from now, she will have already develop big breasts before the vampire could.

While spending her time with the Guardians in private, Aura was deeply stress not knowing what is troubling their master Ainz. She ask them to move on to the next topic, suggesting others to remind which one of the 41 Supreme Beings' words will they be discussing for this meeting. Learning that it was the words of Herohero they had to analyze carefully over health exam, Aura figures "the liver was red" meant that any red-blooded living creature had a red liver. Aura promised the other Guardians that she is willing to do anything as long as it is for their master Ainz.

The Dark Warrior Arc
After Ainz reads Aura's report, it is shown that they have not yet made contact with YGGDRASIL players nor have they found any trace of them. She has done a search of the forest near the Great Tomb, and she has found a lake among the foothills of the mountain range at the end of the forest.

While Ainz masquerades as an adventurer, Aura is given the task of investigating and controlling the interior of the Great Forest of Tob. At the same time, she has to gather up any lifeforms who are willing to join Nazarick along with setting up the construction of a warehouse for resource storage and emergency shelter.

After Ainz and Narberal enter the Great Forest of Tob with Nfirea and the Swords of Darkness, Aura is shown to have been following behind the two ever since then. On the other hand, she is ordered by Ainz to lure out the Wise King of the Forest and have it attack them. In order to reach her intended destination of where the beast is at, she regroups with her pets Fenn and Quadracile to carry out the task. Upon arrival at the creature's hideout, with her special breath skill, she easily manages to direct and aggro the Wise King of the Beast straight toward them.

Although she wanted to make that creature as her own familiar, Aura refrains from doing it for the sake of Ainz's order as it takes precedence first. She ponders whether it was fine for her to take the creature's pelt after it dies by the hands of her master. When the creature surrenders to Ainz, Aura offers a suggestion where they should kill it and take its hide to make a great pelt. Much to Aura's regret, her master allows the creature to live and pledge its loyalty to him.

The Bloody Valkyrie Arc
As Ainz proceeds to engage Shalltear in a death battle, Aura and Mare have been ordered to monitor the area. She was also supported by Eyeball Corpses summoned by Ainz to help her with the targeting duties and keeping their surroundings occupied. Having been given World Items for protection, the two are given the additional order of withdrawing when the enemies appear.

While Ainz had a death match with Shalltear, Aura was using her ranger skill [Sky Eye] from afar to keep a close watch over how the battle between the two unfolds. Right before Shalltear lands the killing blow on Ainz, Aura releases one of her skills, making Shalltear feel a sense of hostility from her and hesitate in her attack. This in turn, allows Ainz to regain the initiative and emerge victoriously.

When the battle was over, Aura dispelled [Sky Eye] and silently chastise Shalltear's stupidity for allowing an undead like herself who is supposed to be immune to mind-altering skills end up becoming mind-controlled by the enemy. Since her brother did not know who was victor of the battle, she informs him that their master have emerge victorious. According to her brother Mare, Aura was upset and in a bad mood upon having to see Shalltear be forced by the enemy to take up arms against their master.

After the revival of Shalltear, agreeing with Demiurge's sentiment, Aura and the other Floor Guardians beg Ainz to never get in harm's way again and to allow them to handle any future incidents that may come. Once that matter was taken care of, Albedo reports to Ainz that Aura have discovered a Lizardman Village where they can then plan their next move on.

The Show Must Go On!
In the Great Forest of Tob, Aura begins making preparations to build a second Great Tomb of Nazarick. Noticing that her brother Mare is becoming uncomfortable around her, she asks why. Mare is afraid that she is having thoughts in seceding from Nazarick. Aura states that isn't the case, Ainz arrives and he explains that the structure that Aura is building is a fake tomb to detract invaders. Based on the work she had done so far, Ainz is willing to give Aura a reward for her hard work, though she initially refuses. However, due to his continued insistence about it, she consents, but only if the other Floor Guardians receive something similar.

In a meeting with her peers and master, she requests a taming room to train her animals. Later on, Aura and Mare notice a gathering of the NPCs around a bulletin for try-outs for the role of Juliet in a play hosted by Ainz. Aura declines to participate as she doesn't want to get involved in Albedo and Shalltear's shenanigans. The day before the auditions, Aura is approached by both female Guardians, who offer her high-level artifacts for her vote. Aura ultimately votes for Shalltear, and when Albedo finds out and attempts to get her to admit her guilt, the dark elf states she has evidence of the illicit bribes from both Guardians. Demiurge is informed of this, resulting in the disqualification of both women from the competition.

The Sealed Evil Tree Arc
Aura and Hamsuke accompany Ainz to retrieve a rare herb in the northern region of the Great Forest of Tob. The trio encounter a dryad named Pinison Pol Perlia. Through her, Ainz learns of the awakening evil treant, Zy'tl Q'ae. After Zy'tl Q'ae has fully awakened. Aura, along with other Floor Guardians, are ordered to fight together against Zy'tl Q'ae and to secure the herb for Ainz's adventurer quest from the Adventurer's Guild.

The Lizard Man Heroes Arc
During the morning, Aura is seen giving out orders to a contingent of golems and elder liches in constructing a warehouse in the northern part of the Great Forest of Tob. With her watch's alarm going off, she decides to take a break for the time being. As a result, she tells her coworkers to return back within an hour or so after her break time is over. In the meantime, Aura is served by Pestonya a hamburger with two pickles, french fries with the skin on, and a cola as requested by the former.

After Cocytus loses the war against the lizardmen, she participates in a meeting with the rest of her fellow Floor Guardians about the former's defeat. Before the meeting began though, Aura came across an unknown entity within their ranks which was Victim, a fellow Floor Guardian like them introduced by Demiurge upon asking. During the meeting, she and her brother Mare both cried after seeing how Ainz forgives Shalltear for her betrayal.

As Ainz and the rest of the Floor Guardians, including Aura, are in the fortress built by her, she is praised by her master for the hard-work she did to construct it much to her dissatisfaction. Nonetheless, when Albedo intentionally destroys part of the fortress out of jealousy towards Shalltear's punishment, Aura is informed by the former about accidentally destroying the wall and needing to get that fixed. Aura then informs Ainz about the security net where she dispatches the undead borrowed from her master to patrol within a two kilometer radius. She reports to him, stating that they have not picked up any exceptional intrusions. At the same time, she sends out some of her magical beasts who are adept at reconnaissance to patrol a four kilometer radius around where they are, but there hasn't been reports of anything suspicious so far. When asked by Ainz if there have been any preparations on her end, Aura tells him that Shalltear is helping her deploy the kind of undead that are good at surveillance.

Later, Aura is among the Floor Guardians to discuss about Ainz's persona, Momon. Aura states her concern to Demiurge on it being more damaging to spread the rumors of working with that Vampire after the adventurer becomes famous. Nonetheless, Aura's concern is dismissed when it is treated as malicious gossips at that time since Momon is a famous adventurer now. When Demiurge asks Aura on what she is going to do if Ainz ends up being mind-controlled by the same person responsible for Shalltear's betrayal, Aura vows she would kill that person who did it.

When Ainz wants to use her warehouse to speak to Crusch Lulu, Aura strongly protests against the idea as she feels that it is not suitable for Ainz. Ainz then comforts her, saying that the place built with her feelings is as good as Nazarick. The Floor Guardians, upon hearing this, immediately proclaim the place as such for Aura to listen and understand while they permit Crusch to enter.

The Search for Hamsuke Arc
Aura is ordered by Ainz to find Hamsuke, who has gotten lost somewhere on the 1st Floor of Nazarick. Learning that Shalltear is also in on the search for Hamsuke, she looks to compete with her of whoever can find it first, mocking the vampire that she lacks a sense of smell compared to herself. She asked Ainz whether it was fine for her to skin Hamsuke's pelt if the hamster was found dead much to the latter's doubt. After checking the 6th Floor and not being able to smell the scent of Hamsuke nearby, Aura and her brother try finding the hamster to the 2nd Floor and are soon joined by Albedo and Shalltear. With Aura picking up an animal scent that is close to them, she teasingly mock Shalltear for not being able to smell Hamsuke's presence while she could.

While Aura is in the lead, the four eventually came across Hamsuke. However, none of the female Floor Guardians including Aura want to approach the beast, as much to their horror, the hamster has a cockroach lying on top of its head. Aura and the two Guardians encouragingly push Mare to use his staff to crush the bug, but the boy is unsure how, afraid of killing Hamsuke. Aura warns his brother that if he were to touch it with his own hands, she promised to never go near him ever again. Realizing how helpless Mare is, Aura threatens Hamsuke to remove the cockroach or else she will peel off its skin. As a result, the antics of the Guardians cause Hamsuke to flee in terror after being threatened with death if it comes any closer.

The Two Leaders Arc
While in Nazarick, Aura informs her master that she did a quick sweep on the forest and in the end, hadn't find any strong enemies nearby except the monster, Zy'tl Q'ae they fought against. It was decided that Aura would join Ainz in helping him eliminate the two remaining rulers of the forest once and for all so that they can finally put their surroundings under Nazarick's complete control. After heading outside the tomb, Aura accompanies Ainz using her pet Fenn to ride together and meet with the Giant of the East and the Serpent of the West at the Great Forest of Tob.

During her travel there with Ainz, she discusses with him about how they should deal with the enemies. Let alone that, Aura is asked by Ainz of her well-being and she tells him that she is still young and well. She vows to eat well enough for her growth to Shalltear regret it. Aura is told by Ainz that he wishes to see her find a lover someday, to which the former believes it is still too early for her due to her age. When asked who she likes the most in Nazarick, Aura admits it to be Ainz, to which the latter reciprocates, much to her dumbfounded surprise. She makes a promise with Ainz to accompany him during his travel to a kingdom of dark elves in the near future if found.

Once they almost reach the lair of the Giant of the East, Aura stations all of the magical beasts she brought along with her around the region to set up an encirclement under Ainz's order. Upon reaching their lair, talks of negotiation begin, but end in failure, as Aura captures Ryraryus, who tries to escape, while Ainz kills Guu and all of his minions with Despair Aura V. Although Ainz wanted to avoid violence and have a peaceful talk before negotiations broke down, Aura reassures her master that it was their fault for trying to lay a finger on him.

Aura, along with Ainz, returns to Nazarick. During her break time, she hangs out with Albedo and Shalltear on the 6th Floor, talking about the Bicorn. After Albedo summons and explains her Bicorn, Aura can't help but be impressed by the latter's appearance while the two starts exchanging words regarding its equipment and Albedo's skills over it. Aura have also discusses problems surrounding Albedo's Bicorn mount, with Albedo being unable to ride it. Aura believes it could have be because of the Bicorn's muscles being wasted away due to the summoner not choosing to ride it regularly enough. Aura informs Albedo that she has to raise all her pet familiars free-range, having to always make sure they were patrolling around the 6th Floor frequently. Aura tries establishing communication with the Bicorn, but fails as it is not one of her minions she controls. According to Aura, this is not the first time this has happened to her before, recalling the time when she failed to communicate with the lizardman's hydra, Rororo.

Having trouble finding the solution to their Bicorn problem, Shalltear brings out her Game Encyclopedia, which was owned by Peroroncino much to Aura and Albedo's jealousy. Although she is initially jealous of the gift Shalltear got from Ainz, Aura's envy immediately goes away when she caresses the silver wristband that was gifted to her by their master. Upon finding information on Bicorn from Shalltear, including how it can only be ridden by impure maidens, Aura is left utterly dumbfounded and shocked after discovering that, despite being a succubus, Albedo, is still a virgin.

On the other hand, Aura gives suggestions to Albedo on what the Bicorn should be equipped with. Additionally, she asks Albedo if there was a name for this Bicorn, to which the latter said there is none, which encourages the former to suggest giving the mount a name. Along the way, Aura reveals to Shalltear and Albedo what her day-to-day life has been like until now, which includes bringing in new residents to the 6th Floor and patrolling the forest. She then gives her colleagues a detour around Green Hole, where the newest residents of Nazarick are at, detailing the role Mare has there and monsters like the Spear Needles under her control. Aura greets Sous-chef during her visit and introduces the Mandrakes that she has trained to the two female Floor Guardians.

On a different topic, when Shalltear shows concern about how Albedo not being familiarized with these new residents may hamper Nazarick's security, Aura makes sure to explain the different floors in details as there is no possible way out of the tomb except death. In addition, Albedo details the progress in Ainz's plan of Project Utopia that was started by the secret base Aura built. Aura decides to part ways with the two after hearing from Mare via communication with her magic item that he needs to head out, which requires her return to the Amphitheater. She learns that Mare is going to pay a visit to Cocytus on his floor much to her suspicion. Nonetheless, before allowing her brother to go, she warns him to come protected on the 5th Floor while visiting the said Floor Guardian as his domain was very cold.

Meanwhile, Aura is ordered by Ainz to keep an eye on the both of them. For that reason, she is placed in charge of the women’s group in the female bath. While in the female bath, the Lion Golem attacks the female Guardians, including Aura, for their bad behavior in the bath and Ainz and the male Guardians prepare to help them.

The Dark Hero's Story Arc
Aura and her brother attend a meeting with the rest of the Floor Guardians to decide what kind of rewards they wish to receive from Ainz. Aura voices her wish to be given Rororo as a reward. Her request is immediately rejected by Cocytus, as the hydra is the property of the lizardmen, which are under his jurisdiction.

Even though Aura's request is denied by Cocytus, she then requests to have the pet's children instead. Simply put, Aura wants to take the children of Rororo to the 6th Floor of Nazarick and raise them in the pond there. Cocytus doesn't turn down the request right away, but will first try asking about it to the lizardmen and reminds Aura that she can't take it from them forcefully.

When hearing Mare's outcry to not lowering the coupon's price for sleeping with Ainz as disrespectful, Aura reassures her brother that the price being low is nothing more than just an example.

Ainz Raises Money Arc
Aura is present with her fellow Floor Guardians at a meeting with their master Ainz Ooal Gown. During the meeting, when Ainz inquires the reward that Aura wants, she initially thinks of obtaining Rororo, but cannot do so because it is under the control of Cocytus's lizardman. After Cocytus explains the situation he had with Aura, she then follows it up, stating that she now suggests an "Eat With Ainz-sama" voucher.

Like the others, she is given three gold coins to be used as her salary by Ainz. In the next meeting, Aura presents her liege about meeting a human smith and had that person make those gold coins into a pair of bracelets.

During another meeting with Ainz, Aura presents her master a wooden Momon statue she bought.

The Men in the Kingdom Arc
Aura and Mare break into the executive council of Eight Fingers, leaving them utterly shocked by the two elves' sudden entrance. Upon arrival at their base, Aura uses her power on members of the executive council, preventing and paralyzing them from making their escape. At the same time, she informs them that from this moment onward, they will become Ainz's new servants. As a result, Aura dominates them by using her breath ability and celebrates the idea that they will be puppets of Nazarick. While this is happening, she warns Hilma to not think of betraying Nazarick or else, she will be sent back to Kyouhukou's room and stay there for a longer period of time than previously.

The Invaders of the Large Tomb Arc
When the Great Tomb of Nazarick is infiltrated by four groups of workers, Aura is seen at the Amphitheater, where one of the groups, Foresight, has been teleported to. As the group arrives in the arena, Aura announces the arrival of Ainz as their challenger. During the battle, Aura follows her master's order allow one of the members, Arche, to escape, with Shalltear being ordered to tormentingly hunt down and kill Arche mercifully.

Later, after Ainz defeats the group, Aura is then ordered by her master to take two of the members, Hekkeran and Imina, to the large hole, stating that Gashokukochuuou is running out of "nesting room." Hearing this, Aura immediately asks if she can have Mare do it for her, to which he agrees.

After the massacre of the workers, Aura and Mare, as envoys, visit the imperial palace using dragons to fly to their destination. Once there, she introduces herself and then threatens the Emperor Jircniv, telling him that if he doesn't apologize for the invasion, they will destroy the whole Baharuth Empire. In order to make an example out of her words, Aura orders Mare to use his magic and kill the humans present at the courtyard, much to the Emperor's shock.

With the deed done, Aura eggs the Emperor to show himself to them. If not, she will even order the annihilation of their city, Arwintar. As a result, Aura has successfully forced the Emperor to reveal his whereabouts face-to-face with them. Thereafter, she and her brother are prepared and welcomed by the Emperor's subordinates reception at their palace.

The Magic Caster of Destroy Arc
In the Imperial Palace, while waiting for talks of negotiation to begin, Aura and her brother Mare are given beverages to drink as part of their reception. Hearing how she didn't find it to be tasteful, Jircniv suggests he will prepare better ones next time, wiwth Aura doubting that they will have any good drinks to impress her. She and Mare are bombarded with question after question by the Emperor much to her annoyance. Finally having enough, she then asks whether he will come to Nazarick and apologize for his actions. If he chooses to not visit Nazarick, she will relay the message to Ainz about it and return back to this city and destroy it thereafter. Aura tells the Emperor that her master wants him to come over once the latter makes his decision.

In the end, the negotiation ends after they hear the Emperor's answer, leaving both Aura and Mare to head back to Nazarick and inform Ainz while waiting for his arrival within five days' time. After the meeting delegation comes to an end, Aura learns from Demiurge that the Emperor is scheming against Ainz, with Aura believing that Jircniv is surprisingly stupid to try and do. She is angered upon learning that the Emperor is trying to have one of them betray their master. While deciding on a name suitable for Ainz, who will ruled over the Sorcerer Kingdom, she suggests he pick the title Powerful King, or Power King in short.

The Ruler of Conspiracy Arc
In the morning, Aura and her brother pay a visit to Ainz, reasoning that they're simply here to greet and see him. Thanks to Aura, the fortress in the Great Forest of Tob as the fake Nazarick, or perhaps a resource depot has been completed for now. Aura’s next task is to conceal the fortress and strengthen its defenses.

At the same time, both of them are picked up by Ainz, placed on each lap, and coddled in fatherly affection. When Albedo is sitting on Ainz's lap, he attempts to breathe in a familiar scent, which Aura later stops her master from doing so, telling him brashly that it is perverted. According to Albedo, Aura has been sitting on Ainz's lap for around 3 minutes and 41 seconds much to her jealousy. When Albedo won't get off Ainz as their master order her to, Aura provoke a reaction from the Overseer, telling her that she was only here to visit him not out of work reasons like the former but because she wanted to see his face.

The silent stare down between the two stopped right after Aura was asked by Ainz what happen to the elves. Aura answers saying that the Elven Slaves are on the 6th Floor of Nazarick taking care of both her and Mare much to her annoyance. She advised Mare to learn how to get dress better independently or else the elves will keep lending him their assistance. Ainz hopes that they can help with Aura's and her brother's development as fellow dark elves and as parental surrogates.

Additionally, Aura, alongside her brother, decides to make a suggestion to Ainz that boys should wear girl clothes, and girls should wear boys' clothes. However, the suggestion is struck down by Ainz when he convinces everyone in the room that the two dark elves are dressed that way because their creator, Bukubukuchagama, wanted them to be special. Hearing Ainz's reasoning because of that, she keenly reflect on her inconsideration towards her creator's feelings and will.

Learning from Albedo that their resources in the Sorcerer Kingdom are turning out insufficient, Aura offers a suggestion that they should grab more from either the Empire or Kingdom.

The Pleiades Day Arc
Aura is notified of Yuri Alpha's entry to her floor and is informed that she is looking for Shizu. Aura brings Yuri Alpha to Shizu, who had wrapped her body around one of Aura's Spear Needle's, causing it great discomfort.

After Yuri extricates the automaton from Aura's pet, they are joined by Neuronist Painkill, who explains that she is going to a house-warming, bring a gift of perfume. Aura, confused at the gift, inquires what it is, humoring Neuronist on her childish behavior and offers to educate the young dark elf in being a 'lady'. Though due to her close proximity to Neuronist, she causes Aura to run back to her floor.

The Craftsman of Dwarf Arc
Ainz decides to use the NPCs to be his bodyguards on his journey to the Dwarf Kingdom. According to Ainz, the only suitable bodyguards for him are Aura and Shalltear. In other words, Aura and her magical beasts could be considered an ideal choice for this trip there.

Later, Ainz contacts Aura and Shalltear to meet him in his chambers at E-Rantel. Aura came first, so she was informed by her master that they will be visiting the Dwarf Kingdom along with Shalltear. This surprises Aura because she figured that Shalltear has very limited uses. She presumes Ainz's decision to have Shalltear accompanied them was her master's plan to destroy the nation after foreseeing that peaceful negotiations are bound to break down. Aura's misunderstanding was clear up after she was told by him that Shalltear's reputation as the strongest Floor Guardian has been hampering her growth all this while and wants the vampire to accumulate various experiences to make up for it much to her surprise.

Upon Shalltear's arrival, Aura tells her to wait for Ainz to finish speaking first before she starts getting the wrong idea of why she was recruited into his expedition. Under her master's order, Aura was informed that they will be visiting the Dwarf Kingdom together and how Shalltear must obey her every command throughout the journey. Aura and Shalltear were advised by their master to make sure and bring the right familiars along for traveling.

While her colleague Shalltear vows to redeem herself from her past failure, Aura offers her prayer to her creator to watch over Shalltear. As the vampire thinks she had been given easy tasks as of late, Aura encourages and reason with Shalltear that any work given to her by their master is still very important regardless. When the vampire felt doubts of her own inability to be useful, she convinces Shalltear that Ainz's judgement to have her participate in their mission was his choice that not even Demiurge could have thought of doing. She reasons that since their master is smarter than Demiurge, it was why Ainz chose Shalltear in the first place. She informs Shalltear that Ainz is looking to test her flexibility by exposing the latter to various difficult situations. With that said, Aura advised Shalltear to study and learn her surroundings while they traveled.

Aura and Shalltear gathered at the lakeside near the Lizardman village, accompanied by their hand-picked followers. Among which were 30 of the magical beasts Aura have decided on bringing with her for the expedition. While waiting for other members to arrive before beginning the journey, she and Shalltear started making preparations with their familiars in the meantime.

Once their journey to the Dwarf Kingdom began, it was Aura's duty to record their travels for the day using a memo pad to sketch a map of where they're at whenever they're on a break. During one of those break times, she notice Shalltear was hard at work taking notes of their master's words in great details. Seeing this, Aura advised the vampire to not always write everything word to word what their master says but instead, suggested the former try recording the important things down and using them to teach herself how to deal with similar situations. For instance, Aura hints that Shalltear should think about what Ainz had in mind and then put herself in his place and imagine what she would do in his shoes. She ponders if this was like what her creator went through when taking care of her own sibling.

At some point in their journey, they eventually arrived at the entrance of the dwarven city but discovered that the city was already long since abandoned. Having the best senses, Aura was given the order by Ainz to search for any sign of life in the city. Aura discovers a footprint in one of the abandoned buildings on their way to the home of the dwarf, who took care of Zenberu and it's clearly not a dwarf. As Aura continue to lead the search in the city, Ainz received a message from the Hanzo, informing him that they found a trace of someone's presence in the tunnel. Ainz orders Shalltear, Zenberu, and the others to stay on guard at the entrance of the tunnel while Aura and he proceed to investigate a hidden tunnel. Once there, Aura happens to identify a new set of footprints of a person who was nearby.Aura was encouraged by her master to establish a peaceful contact with that person and have friendly dialogues with it.

As a result, what Aura found was a lone dwarf miner digging in the tunnel all by himself. With her master hiding his presence, Aura then proceeds to meet the Dwarf and ask him a question. The dwarf was startled by the sudden appearance of the dark elf and uses the cloak of invisibility to hide his presence. Aura persuades the dwarf that she doesn't intend to hurt him and wants to look at him. The dwarf reveals himself and wonders what a dark elf doing here. Aura introduces herself as the emissary from the Sorcerer Kingdom and the dwarf introduces himself as Gondo Firebeard. Aura asks Gondo why there are no dwarves in the city, he tells Aura that the city was abandoned three years ago due to the Quagoa, an underground dwelling race just like the dwarves, and also told her that the Dwarven Army are ready to recapture their old capital city from the Quagoa.

When Ainz revealed himself before Gondo, Aura prevented him from running away much to his horror initially. Upon seeing how trustworthy Aura was and its faith to her master, the dwarf decided to cooperate with Ainz. Later, under Ainz's order, Aura was given the task to tail after Shalltear, keeping close watch over her movement as she is in pursuit of the Quagoa who are nearby. If Shalltear was about to begin massacring them, Aura was tasked with the job of stopping her by any means necessary, even if she have to hit her. Other than that, Aura was told not to interfere with any of Shalltear’s battle plans.

When Ainz is looking to prepare himself before the Regency Council, Aura and Shalltear worked together to decide on a fitting attire that he could wear for the meeting. Later after traveling to Feo Jera to negotiate with the Regency Council, Aura was present when Ainz rallied the remaining runesmiths to his side and praised him for her master's accomplishment of swaying them over to their side. Aura, Shalltear, Ainz, and Gondo traveled together to the old dwarven capital to fight the Frost Dragons and the Quagoa. Aura and Shalltear collaboratively, are ordered to face the Quagoa and have them submit to their master's rule even if they have resort to violence including reducing their population in doing so. To ease her concern of not being able to prevent all the Quagoa's escape, Aura was allow permission to use the World Item, Depiction of Nature and Society on them for that mission.

Along the way, they encounter a young Frost Dragon by the name of Hejinmal, who quickly submitted to Ainz Ooal Gown. After receiving meaningful information about its dragon-kins and abilities, Ainz decided to give Aura this Frost Dragon as her new pet to take care of. Agreeing to his offer, Aura uses some sort of unknown skill or ability to bend the Frost Dragon under her full control as it's boss much to the latter's pain and terror. Although she felt initially disgusted of the dragon peeing, Ainz reasoned with Aura that Ankoro Mocchi Mochi had a pet dog that does the same out of joy and excitement. Hearing this, Aura learns that perhaps her other familiars may undergo the same behavior like Hejinmal to mark their terrain.

Later on, Ainz orders Aura and Shalltear to begin giving the Quagoa an ultimatum while he and Gondo proceed to the Throne Room. Outside of Feo Berkana, Aura activated her World Item to trap the Quagoa from escaping. She order the Hanzo to block off the escape route from within the world they are trapped in. She and Shalltear discuss about what effective powers from the World Item they can used on the Quagoa and how to cull their numbers. At the same time, she and Shallear question the meaning and intention behind Ainz's action surrounding the fall of the Death Knights. Once she sense a massive number of Quagoa are close by, Aura and Shalltear confront its leader Pe Riyuro. She and Shalltear gave him an ultimatum and declared that they had been sent to let the Quagoa know that they were to be taken to the Sorcerer Kingdom. In the end, they successfully accomplished their operation and report back to Ainz.

Nazarick Mythology Arc
Aura and her brother Mare attended a meeting to create a mythology of their master in order to solidify his hold over the masses. In the twins' myth story, they weave a classic super sentai story where a group is known as "The Ainz Five" fight monsters to save the world until they decide to eradicate the human race. The humans attempted to resist but the Ainz Five transform into a giant golem wiping out humanity in a never-ending cycle.

The Witch of the Falling Kingdom Arc
In the Audience Room Aura was present with the other Floor Guardians. There she saw Shalltear bring Hilma Cygnaeus to present her 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 Aura 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 maybe Philip did what he did without thinking about the consequences of his actions first, Albedo doubts the nobleman to be this stupid. However, as Demiurge shows his support to Ainz's notion, so do Aura and her brother. With Ainz permitting questions to be asked by the Floor Guardians, Aura was the first to question the strategy of their operation. Aura wanted to know why they did not draw in as many of the nobility as they could during the beginning of the operation. She thought if they had done that from the start, they could have just killed off the troublesome noble, Philip and continued the operation as they had planned. Demiurge answers Aura's question, stating that would have been troublesome as none of the noblemen are exactly known for their intellect and adding them into their operation could have caused an unexpected leak in intel to occur.

As Demiurge inquires further from the Floor Guardians on what punishment they should impose on Philip, Aura suggests the idea of killing him which her brother also agreed with doing.

Since one month have pass by after the Sorcerer Kingdom's declaration of war, Aura was among one of the Floor Guardians to have been able to successfully lay siege on territories be it a city or village within the Re-Estize Kingdom.

When Ainz was at the Re-Estize capital with his 10,000 undead army from the Sorcerer Kingdom, Aura happens to be present there with him during that moment in time. Like her brother Mare, Aura was also watching the soldiers on the side as they build and manage the fronts. At the same time, she has also been observing her own servants while standing by her master's side. Once Ainz gives her the order that she must protect him using the World Item, Aura obediently obeys her master's command without any hesitation. After Ainz returns from his meeting with Zanac, Aura had a discussion with Mare and Cocytus about the upcoming siege of the capital. She was later issued an order by her master to not heed the wishes of 1) people who do not want to die and 2) people who desire death once the battle begins.

Once the battle began, Aura and her magic beasts set off from the front she had established in front of the capital. Aura was the one in charge of crucial facilities.
