Luna Auah

Luna Auah is the former heiress of the New Sylvane and is Second in Command in the Evesta’s Council.

Moments before YGGDRASIL is expected to shut down, Momonga changed Albedo's character information to be in love with him as a joke. Albedo is the first NPC to speak to Momonga when the Great Tomb of Nazarick is transported to the New World. Confused at Momonga's strange behavior, Albedo asks him if there was something wrong and whether he required anything of her. She apologizes to Ainz for not meeting his expectation such as her own inability to answer the latter's questions about the "GM Call" he spoke of. Under Momonga's order, Albedo was experimented upon by her master to see what changes had been done to the NPC after the end of YGGDRASIL where she became sentient.

Albedo was given the order by Momonga to assemble the Floor Guardians except for Victim and Gargantua on the 6th Floor, Amphitheater. She and Demiurge are the last Floor Guardians to arrive. She including the Floor Guardians introduce themselves and pledge their absolute loyalty to Momonga. Representing the Guardians, she would go on to offer several statements of respect to Momonga before then personally describing the love she had for his greatness in her own words. She informs Momonga about the exchange of security information between the Guardians of the various floors and how everyone can share information with Nazarick's defense commander Demiurge. She was ordered by Momonga to work together with Demiurge of drawing up a more comprehensive administrative system for managing the Great Tomb of Nazarick barring the 8th Floor.

After the meeting is over and Momonga had left the Amphitheater, she and the Floor Guardians discuss their impression of their master's Despair Aura that they felt while in his presence. Although she was envious at first by how Aura said that Momonga was kind to her and her brother Mare, Albedo let go of the jealousy and express honor and fondness for what their master had shown them. Before allowing the butler to return to their master's side, Albedo tells Sebas Tian to call her immediately if Momonga was to ask for her summon which she will promptly obey in the event that it happens. Seeing Shalltear Bloodfallen wetting herself after feeling Momonga's presence, she scorn and belittle the vampire's behavior as sluttish. Shortly thereafter, she got into a catfight with Shalltear Bloodfallen, throwing harsh slurs at each other and quarreling about who is worry of becoming Momonga's first wife. She puts her argument with Shalltear on hold when it was time for her to issue orders which Floor Guardians like themselves have to carry out.

Later, she came across the Evil Lords without Demiurge present alongside them. Suspicious of his whereabouts, Albedo inquires Demiurge's servants where the demon is at and who he is with. She was angered by the fact that the Evil Lords were trying to deceive her with false information of there being a Dark Warrior among Nazarick's lowly servants who accompanies Demiurge. Upon threatening them to spill the beans, she learns that the Dark Warrior is none other than their master Momonga much to her shock. Albedo was convinced by the Evil Lord Envy to not take a bath and change her clothes whatsoever as it will be enough to appeal to Momonga that she has been working very hard. She part ways with them soon after to chase down Momonga and Demiurge. She confronted Demiurge at some point during her searching and was brought along to where Momonga was at with Mare Bello Fiore. She reasons with Mare why Momonga is wearing armor was so that their master can silently concealed his identity because he did not wish to disturb the others at work. Albedo explains to Mare that Momonga's disguise as Dark Warrior was to prevent others like themselves from ceasing in their labors. She elaborates that if Mare was to found out Dark Warrior was his master all along, he would end up stopping work to pay their respect to him afterward. Due to her duty in the tomb as the Guardian Overseer, she was given the Ring of Ainz Ooal Gown by Momonga to help with navigating around Nazarick.

Albedo was informed by Sebas to be by Momonga's side fully equipped with the exception of her World Item, Ginnungagap. As a result, Albedo accompanies Momonga to save Carne Village and stop the Sunlight Scripture who arrived to attack it. She was ordered not to kill any innocent humans like Enri Emmot and Nemu Emmot as their objective in the first place was to prevent such harm from happening and to rescue them from danger initiated by the Sunlight Scripture. During the fight, she dislikes seeing her beloved Ainz get disrespected and hurt by the enemy's attacks and would sometimes intervene if the situation spirals out of control. Along the way, she had became the first to learn and acknowledge Momonga's new identity that he will go by from now on, which is Ainz Ooal Gown. After the fight with Sunlight Scripture, she and Ainz return to Nazarick with the Sunlight Scripture members they have capture be brought over to the Frozen Prison for interrogation. She even learned from her master Ainz why he had chosen to spare the humans in Carne Village and Gazef Stronoff alive for supposed reasons that got the Overseer to believe they have some uses in the end. Upon returning back to the tomb, Albedo and other Floor Guardians like Demiurge prepare for their own future plan on taking over the New World for Ainz.

Besides that, she works on her latest task of collecting enemy corpses lying on the battlefield outside Nazarick that they have killed to prepare for the creation of permanent undead minions. She also collects their items to be sent off to Nazarick's Treasury for further investigation. Although Ainz feels guilty of changing the Overseer's character setting, Albedo reassures him not to fret over it as she is fine with whatever modifications he had done to her. She had no intention of returning to her old original self, telling her master that her creator Tabula Smaragdina will approve his action while giving herself away for marriage to Ainz. Albedo is visited by Ainz, who is taking a survey on his subject's relationships and desires. Being the last on his list, Ainz realizes that she has been living in the Throne Room since her creation. He resolves to give Albedo a room of her own, despite Albedo believing her place is in the Throne Room. But she quickly accepts, thinking she will be staying in Ainz's room, but she is declined. Ainz grants her a room on the 9th Floor as she gathers her belongings from a hidden wall in the chamber. She shows an embarrassed Ainz that it contains lingerie that had been given to her by Tabula. In her new room, Albedo takes out the flag of Ainz Ooal Gown and begins desecrating it, cursing it and 'them' for taking her lover's name.

Albedo was given the order to restrict the creation of new magic scrolls in Nazarick while also making sure to minimize their uses as well. Along the way, she has to try and find new materials in the New World that Nazarick can substitute from YGGDRASIL. Seeing how restless Ainz is working, she suggests her master take some time off and rest by having a break.

When Ainz suggested the Guardians take a vacation, Albedo was deeply agonized at the thought of having to lose one whole day just for a break time without work suggested by their master. Albedo frantically admits that if someone as herself can't be allow service to Ainz for such a long period of time, she'd much rather be tortured by Neuronist Painkill instead. Albedo would go as far as to say that she will accompany Ainz and stay by his side at all times. Seeing this, Albedo was order by Ainz to calm down, insisting she and the other Guardians need to take daily rests from now on.

While on her walk to the meeting room, she spotted a stain within her line of sight and vows to tell Eclair Ecleir Eicler to clean it up later. Spending her time with the Guardians in private, Albedo evaluate the result of the health examination for Ainz being estimated between yellow to red. She recalls during her previous discussion with them where they agreed "black" represented "darkness," concluding the meaning of this color to be the result of an unknown spell or curse related to "darkness" that had an effect on Ainz.

However, upon looking at the current result of the health exam, she sees it to be in the "almost all yellow," presuming that had something to do with paralysis among the bad status effects. She laments at her powerlessness to support Ainz during his hour of need, remembering how he made mention of a "GM Call" to her much to her own ignorance. She informs everyone that if they continue receiving their master's kindness, Guardians like themselves including her will be nothing more than failures in the end. She promised the Guardians that they must show Ainz the value of their existence to him by devoting themselves to their master's orders from here on out.

In Ainz's office, Albedo was present to give her master different reports involving Nazarick's advancements and missions within the New World. When Shalltear received an audience with her master, Albedo tells the vampire that she should leave as she and Ainz are currently focusing on important work like deciding the future of Nazarick. This later proceeded into a catfight Albedo had with Shalltear until their master Ainz orders to refrain from such action in front of him.

When Ainz was able to depart from Nazarick with Narberal Gamma as his partner in E-Rantel, she unlike the other Guardians objected his decision the most strenuously. Although she was frustrated of not being able to accompany her master on his journey, Albedo was convinced by Demiurge to leave their master be when he suggested the Guardian Overseer be a good wife and wait for her husband at home and mind the house in his absence. Hearing this, she decided to stop resisting Ainz's decision and instead, act like a wife and stand watch over her master's room while waiting for his return to Nazarick. During the meantime, she discuss with Eclair about his duties on the 9th Floor of Nazarick since Sebas is absent from the tomb. Once Eclair is gone, she starts enveloping Ainz's bed with her fragrance before he heads to his room. She even pretends to talk with an Ainz Dakimakura that look like her master much to Demiurge's disbelief. Albedo tells Demiurge that she had not only made this body pillow but also clothes and socks for Ainz's future child as well, welcoming any kind of gender the baby will end up being.

With Demiurge preparing to set off from Nazarick, Albedo was informed about his departure beforehand. She had already made preparations for Nazarick's defenses in the event that an emergency arises within the tomb. Prior to him living, she discuss with Demiurge about the ways and rules that he had been conducting with his healing experiments. As NPCs are created by the 41 Supreme Beings to remain loyal to their creators, she was disturbed to see that the human captives trapped in Nazarick would go to great lengths in betraying their own masters to ensure their own survival.

While Ainz is away gathering more information as an adventurer at E-Rantel, Albedo is left in charge of managing Nazarick. Albedo is seen lying naked in Ainz's bedroom when Narberal contacts her, updating the Guardian Overseer on their master's status and what he was doing as an Adventurer. She was informed by Narberal about how Ainz stated that there was nobody else in Nazarick who he could trust apart from her with the task of overseeing the tomb in his place. She was seeking to better understand where her relationship with Ainz is at by using Narberal to relay news to her of what their master think of the Overseer. She learns that three members of the Pleiades, particularly Narberal Gamma, Yuri Alpha, and Lupusregina Beta are supportive of her intimate relationship with Ainz. Hearing this, she orders Narberal to quickly win over Entoma Vasilissa Zeta, CZ2I28 Delta and Solution Epsilon to her side instead of Shalltear. Albedo is appalled when she hears that Narberal is sharing a room with Ainz to the point that she fuss about it much to her master's annoyance.
