Aureole Omega (オーレオール・オメガ, Aureole・ω) is an Area Guardian of the Cherry Blossom Sanctuary and the leader of the "Pleiades Seven Sisters," the battle maid squad of the Great Tomb of Nazarick.

She is in charge of the Teleportation Gates throughout Nazarick. At the same time, she is also tasked with protecting the Staff of Ainz Ooal Gown in the Cherry Blossom Sanctuary.


Aureole Omega is a young girl, no different from a regular human. She's usually seen wearing the traditional attire of a Japanese miko, or a shrine maiden, or a supplementary priestess of Shintoism. This includes a pair of red hakama (long, divided trousers) and a white haori (kimono jacket). Whether she uses any hair ribbons, as traditional miko do, is unknown, as her appearance is largely inferred according to the discussions between NPCs.


Solution knowingly sees her sister, Aureole Omega, to be a rational person, since she wouldn't have come to the same decisions as Sebas. Her sister, Yuri Alpha described Aureole as someone who is high-spirited. Yuri has also imagined the thought of Aureole crossing her arms with an adorable smile on her face. Her manner of speaking is calm, with a gentle voice.


Aureole Omega is the leader of the "Pleiades Seven Sisters" and the Area Guardian of the Cherry Blossom Sanctuary that controls all the teleportation gates in Nazarick. She is the only human NPC of Nazarick that possesses eternal life.

According to her older sister Yuri Alpha, Aureole Omega is usually the person who would know the movements and whereabouts of all of the Seven Sisters.

When Ainz sent out his Death Knight to interview each of the Floor Guardians, Aureole Omega noticed its presence when it used the Gates. Seeing that the undead wasn't an enemy, she allowed its passage.[2]

The Men in the Kingdom Arc

Ainz switches the Pleiades from the Six Stars to the Seven Sisters. Even so, Ainz does not allow Aureole Omega to move from her current position and thus, Yuri Alpha becomes the temporary leader of the Seven Sisters.[3]

The Two Leaders Arc

When Nfirea, Enri, and Nemu were teleported to the 9th Floor during their visit to Nazarick, Enri briefly caught a glimpse of Aureole Omega during the transition.[4]

The Pleiades Day Arc

Main article: The Pleiades Day Arc

Aureole was contacted by her older sister Yuri Alpha to confirm the location of Shizu Delta who was on the 6th Floor of Nazarick. She suggested Yuri borrow her servants, the Uka-no-Mitamas to lead the way in tracking down Shizu to the 6th Floor, but was turned down. She recommends Yuri to contact her again if neither Aura nor Mare know where she is. With permission from Ainz, Aureole informed Yuri that she wass allowed to take two of her own servants outside the Cherry Blossom Sanctuary at any one time. Although Yuri shows concern whether it was alright to send off her servants outside the 8th Floor, Aureole reassures the sister that it should be no problem considering that she has other defenders besides the Uka-no-Mitamas.[5]

The Paladin of the Holy Kingdom Arc

Main article: The Paladin of the Holy Kingdom Arc

To support the summoned Evil Lord Wrath and Erich String Orchestra in their upcoming battle with Ainz, Aureole Omega was ordered by Albedo to buff the five Greater Doppelgängers who took on the form of all her Pleiades sisters except Narberal Gamma beforehand. Ainz did not expect Aureole Omega to play a major role in this battle until acknowledging that the Doppel-Pleiades were much stronger than they are normally supposed to be capable of doing. He realized that Aureole Omega is involved with the match, considering the fact that she must have been the one who is responsible for enhancing their group's strength and abilities.[6]

Ainz (Isekai Quartet) NOTICE: The following section and subsequent subsections are considered NON-CANON to the Overlord Light Novels.

Mass for the Dead Arc

Main article: Mass for the Dead Arc

When Nazarick was transformed in Nazarick Academy, she was mentioned by Momonga to be under the mental influence, though not listed as a student nor attending class.[7]

During the New Year's event, she was briefly referenced by Narberal Gamma when she wore a miko costume in preparation to fight Shiramochi-ō, citing how much she looked like her younger sister.[8]

Abilities and Powers

Aureole Omega is in charge of overseeing all the teleportation gates in the Great Tomb of Nazarick. If an intruder attempts to enter through it, she will use some sort of unknown portal to teleport or divert the intruders into the isolation area of her choice. When Ainz switches the Pleiades from the Six Stars to the Seven Sisters System, she is now the leader of the Pleiades.

Additionally, she has servants like Uka-no-Mitamas and Ootoshis under her command. According to Yuri Alpha, her sister's servants have the sacred duty of defending Aureole Omega's domain, the Cherry Blossom Sanctuary on the 8th Floor of Nazarick.

Like Pandora's Actor, Aureole Omega is also a level 100 Area Guardian. She specialized in commander-type classes. As a commander, she could issue orders which buffed her allies like Doppel-CZ Delta. Thanks to Aureole Omega, the Doppelganger is able to successfully interrupt Ainz's spellcasting twice despite being below half his level. Ainz viewed Aureole Omega as a wild card and an all-rounder.


  • Gate: Summons a portal, allowing travel of a large number of people over great distances. It is considered to be the highest tier of teleportation magic.


Ainz Ooal Gown

Aureole is entrusted with the protection of the Staff of Ainz Ooal Gown in the Cherry Blossom Sanctuary when it is not in the possession of her master, Ainz.

During Yuri and Aureole's short conversation it can be shown that like all other NPCs in Nazarick, Aureole also holds great reverence and loyalty towards Ainz as one of the Supreme Beings from they respectful and faithful like way she referred to him during their chat.


Aureole is one of the seven Pleiades sister created by the 41 Supreme Beings. She was specifically created by them to see and care for each other as sisters, with Aureole herself being designated as the youngest of the seven. As such, she is doted on by her six older sisters and is generally favored and well loved by them. Aureole herself is shown to have a positive relationship with all six of her older sisters and is the only one in Nazarick to be constantly aware of all of their locations and positions while within the Tomb.

This loving relationship is further emphasized by the fact that Aureole is the only human NPC in the entirety of Nazarick. Despite the majority opinion of all six of her elder sisters seeing humans as nothing more than mere food, playthings or lower life forms to be killed, eaten, toyed with, and murdered by them for their own amusement, Aureole is completely exempted from their general disdain and sadism they show to other humans. This makes her the only human being that the Pleiades do not harbor any form of malicious intent towards.

Yuri Alpha

While the two are sisters, they still maintain a cordial relationship when carrying out their master's order. Reasonably, she is willing to help out Yuri on the job, lending the maid her own minions for assistance if need be. Yuri sees Aureole Omega as an adorable little sister to the point that Yuri had even referred to the maid by her given nickname as "Au-chan."

Lupusregina Beta

As Aureole is her younger sister, its likely that similar to her other sisters, Lupusregina loves and dotes on Aureole. And despite Aureole being a human, its likely that Lupusregina does not hold the same malicious/sadistic intent she usually has to other humans and Aureole is completely exempted from being a potential victim to Lupusregina's "hobbies".

Narberal Gamma

Narberal apparently dislikes almost all the humans she is around with. However, her younger sister Aureole Omega is an exception to those she hated. For that reason, Aureole is probably the only human being Narberal does not in anyways hold any hostility towards.

CZ2128 Delta

CZ's exact relationship with Aureole is unknown, but given the fact that she is the designated youngest sister of the Pleiades and thus CZ's younger sister, its likely that CZ's loves and dotes on her the same way the other Pleiades does as well.

Solution Epsilon

Her older sister Solution viewed Aureole Omega as someone who is not considered a normal human being since she is practically immortal.

Solution herself is shown to genuinely love and care for her younger sister, making Aureole the only human being that Solution does not see as a plaything to be killed and eaten for her own entertainment. This is further shown during the Pleiades's discussion with Ainz regarding humans, where Ainz openly asked them whether to banish Aureole from Nazarick due to being part of the human race. It incited an immediate rebuttal from Solution who doubts an immortal girl as her to be remotely human in the first place.

Entoma Vasilissa Zeta

As Aureole is the youngest sister of the seven Pleiades and thus Entoma's younger sister, its likely that Aureole is the only human being that Entoma does not consider food.


Albedo is likely her superior as the Overseer could recruit Aureole Omega to help her on buffing the Doppel-Pleiades before they begin the battle against Ainz.


  • There is an unknown female NPC in the picture of all 100 level NPCs in Nazarick. As the NPC's clothes is similar to that of miko, it was implied to be Aureole Omega in such attire.
  • She is the original owner of the World Item on the 8th Floor that was given to Shalltear Bloodfallen.
  • Her name is finally revealed in the bonus booklet of the Overlord Movie: The Undead King.
  • She is the only member among the Pleiades to not take part in neither Ainz's nor Demiurge's operation outside Nazarick until Albedo used her to buff the Doppel-Pleiades.


  • (To Yuri Alpha): Yes. When Ainz-sama graced me with his presence, I received permission to send up to two of them outside the Cherry Blossom Sanctuary at any one time.
