ナーベラル・ガンマ

One of the Pleiades, combat maids of the Tenth floor under Sebas Tian. She's a Doppelgänger and, because she's one of the most human-looking of the maids, she is Momonga's companion in his exploration of the new world disguised as adventurers. Narberal takes great pride in this duty, often "wearing" it like a badge of honor. However, like most in Nazarick, she holds great disdain towards humans. This proves troublesome, as she becomes incredibly violent when human males make advances on her.

While operating as a member of the adventuring guild, "Darkness", Narberal operates under the alias of "Nabe", which becomes "Nabe, the Beautiful Lady" when Darkness becomes famous. Narberal's beauty has been compared to that of the "Golden Princess of Re-Estize" by many of the country's inhabitants.
