BackgroundThe Pleiades is the battle maid squad that hailed from the Great Tomb of Nazarick. This unit was programmed to have their members as sisters with the exception of Sebas Tian. While the members of the Pleiades referred to each other as sisters, they were not actually true sisters. This was due to the fact that each one of them was made by separate creators. They were simply designed to act that way around one another.
During the old days of YGGDRASIL, the Pleiades are programmed to be under the command of Sebas. Working together alongside Sebas, the Pleiades are a final raid boss team right that the remaining invaders would battle before challenging the 41 guild members of Ainz Ooal Gown in the Throne Room.
Nonetheless, all of its core members are women of unsurpassed beauty, each with a different type of sex appeal to them. After Nazarick was transported into the New World, three of them (Narberal, Lupusregina, and Solution) are apparently working outside of the tomb as of now. Ainz seems to have picked them because they are one of the rare NPCs from Nazarick who can easily disguise themselves as humans without drawing suspicions.
The Pleiades can be organized in two different formations. One is the "Pleiades Six Stars" and the other is the "Pleiades Seven Sisters." These formations can be switched by changing the leader to Sebas Tian or Aureole Omega. Although the "Pleiades Seven Sisters" have been activated after Ainz tested Sebas Tian's loyalty, he still does not allow Aureole to move freely at the moment. Hence, he decided to make Yuri Alpha become the Pleiades's deputy leader to maintain command over the sisters.
The age range from oldest to youngest siblings are ranked accordingly about the Pleiades: Yuri Alpha > Lupusregina Beta > Narberal Gamma & Solution Epsilon > CZ2I28 Delta & Entoma Vasilissa Zeta > Aureole Omega.

During the day of YGGDRASIL's shutdown, Ainz heads for the Throne Room in the Great Tomb of Nazarick and came across the Pleiades midway during his walk there. Although Ainz admits to having accidentally forgotten their character names, he does recall his guild members bickering with each other over the naming of these NPCs. He later instructed the battle maids to follow him on his way to the Throne Room and then have them on standby after seating himself to the Throne of Kings.
After being transported into the unknown New World, Momonga orders the Pleiades to guard the 9th Floor for possible intruders in Nazarick. They also guard and escort Momonga around Nazarick before the latter came up with an excuse to not have anyone be allowed in following him wherever he goes.

The Paladin of the Holy Kingdom Arc
The Pleiades, specifically Yuri, Lupusregina, Solution, Shizu, and Entoma, under the alias as Jaldabaoth's Demon Maids were used as a bargaining chip in the negotiations with the Holy Kingdom Liberation Army and the Sorcerer Kingdom. Though the resistance had yet to confirm these maids in the Northern Holy Kingdom, they agreed to allow Ainz to take control of them once he had dealt with Jaldabaoth.
During the Sorcerer King's fight with Jaldabaoth and his associates, Erich String Orchestra, a group of Greater Doppelgängers transforms into every member of Pleiades with the exception of Aureole Omega and Narberal Gamma. These doppelgängers borrowed the Pleiades equipment and received a buff from Aureole Omega ahead of time prior to encountering and fighting Ainz in a match.
In the end, Jaldabaoth defeated the Sorcerer King while heavily covered in wounds, later making a retreat after the match to recuperate. Despite losing to him, Ainz was able to successfully freed one of their demon maids, CZ2I28 Delta from Jaldabaoth's control and left it in the hands of the Holy Kingdom Liberation Army.
With all of them except Sebas and Aureole Omega being under level 65, the Pleiades's combat capability is quite low considering the role they have been given. This is because the final defense line of Nazarick is actually concentrated on the 8th Floor. The actual purpose of the Pleiades is just to delay the invaders, allowing all the guild members enough time to gather together in the throne hall and greet the invaders like villains in fiction.
Despite being looked upon as weak by YGGDRASIL standard, the levels of each member in this group from the New World's perspective makes them equivalent to legendary monsters.
While the Pleiades each had completely different job abilities, their maid skills were all equally the same. For instance, they can still perform housework like the Homunculus Maids under the command of Pestonya. In a sense, they could substitute for each other in a professional capacity.
In the Web Novel, it was noted every member of Pleiades is equipped with a battle maid uniform that they wear in direct combat. Considering its defensive properties, rather than treating each respective attire as battle maid clothes, they were functioned exactly more like full plate armor. Additionally, the armor was imbued with top-grade magic through rare data crystals that only players who are over level 90 could get were used for it.

- The dual organization of the Pleiades refers to two different meanings of the word "Pleiades." In Greek mythology, the Pleiades refers to the seven sisters, daughters of the titan Atlas, while in astronomy the Pleiades is a star cluster called the "Six Combined Star" (六連星) in Asia.
- The homunculus maids of Nazarick think of the Pleiades as a kind of idol group, with CZ the most popular among them.
- The members of the Pleiades called each other sisters, but unfortunately, they were not true sisters, since they were made by separate creators. They were simply designed to be that way.
