- "I am Narberal Gamma, one of the battle maids, who swore loyalty to the overlord of the Great Tomb of Nazarick, the supreme being Ainz Ooal Gown. You lower life form should be honored to battle with me."
- -Narberal's introduction to Khajiit
Narberal Gamma (ナーベラル・ガンマ, Narberal・Γ) is a doppelgänger battle maid and member of the Pleiades, the battle maid squad of the Great Tomb of Nazarick. She is the creation of Nishikienrai, one of the original nine founders of Ainz Ooal Gown.
She is also known as Nabe, a magic caster and Momon's adventurer partner of Darkness. She is an adamantite ranked adventurer and one of the most powerful female adventurer in the Kingdom.
Narberal Gamma is described as an elegant, snow-white skinned, black-pony tailed beauty. People believe her beauty is comparable to that of Golden Princess.
She wears a white bonnet in place of a helmet, and black armor decorated in gold and silver in the likeness of a maid uniform. Being a battle mage, her weapon of choice is a golden staff plated in silver. In her adventurer persona, she wears a plain brown cloak.
Her human form is gained through her Doppelgänger's transformation skill. Due to her low-racial level, she can only transform into one form. Her original appearance as a Doppelgänger resembles that of Pandora's Actor.
Like many others in Nazarick, Narberal views humans as low-class creatures. The only human exempt from her contempt is Aureole Omega. Though she does not particularly enjoy killing humans, she will not hesitate to do so if there's no reason to let them live. This nature makes her one of the two, along with Solution Epsilon, "extremely dangerous" Pleiades.
As a created NPC of Nazarick, she is extremely loyal to Ainz and proud of her quest to support him close by. Nevertheless, she doesn't understand Ainz's purpose to become a hero very well, so she does not hide her aggressive attitude towards humans and often refers to Ainz with "-sama", even when the two masquerade as adventurers.
Narberal Gamma was created as one of the battle maids, the Pleiades. They served as a last line of defense against intruders. However, because they were unlikely able to stand against enemy players who managed to come this far, their only real purpose was to buy sometime for the guild members to prepare for their final stand in the throne room.
