Pleiades

Pleiades (プレアデス) is the combat maid squad of Nazarick.

Background
Pleiades is the combat maid squad of Nazarick, programmed as sisters. Unlike other homunculus maids under the orders of Festonear S. Wangko, Pleiades does not have skills for housework and fights under Sebastian as a final raid boss team right before the throne hall. All of them are women of unsurpassed beauty with different types of appeal. After the teleportation, three of them are working outside of the tomb. It seems that's because they are rare NPCs who can easily disguise as human.

Pleiades has two indivisual systems. One is "Pleiades Six Stars" while the other is "Pleiades Seven Sisters". This binary systems can be switched by changing the leader to Sebas or the lastborn of the Pleiades. "Pleiades Seven Sisters" activates in volume 6, yet Ainz does not allow the lastborn to move and thus Yuri becomes deputy leader.

Strength
Considering them as a final boss of Nazarick, Pleiades's combat capability is quite low, all of them except Sebas are under 65 level. This is because the substantive final defense line of Nazarick is in the 8th floor. Actual role of Pleiades is just to delay the invaders and allows all the guild members to gather in the throne hall, and greet the invaders like villains in fiction. However, low power levels in the new world makes them as a legendary monsters.

 * The binary system of Pleiades refers different name of real "Pleiades". Pleiades is called as "Six Combined Star(六連星)" in Asia while ancient Greek thought them as seven sisters.
 * Homunculus maids of Nazaric think Pleiades as a kind of Idol Group. CZ is most popular among them.
