Entoma Vasilissa Zeta

Entoma Vasilissa Zeta (エントマ・ヴァシリッサ・ゼータ, εντομα・βασιλισσα・ζ) is a member of the "Pleiades Six Stars", the battle maid squad of the Great Tomb of Nazarick. She was created by Genjiro.

Appearance
Entoma has the appearance of a girl wearing clothing similar to the traditional Japanese style. Her eyes are cute, but they never twinkle or blink. She has brown hair with twin chignon. She never exposes bare skin except her face.

Her true form is a spider-human (arachnoid). Her face is a mask-shaped insect and her hair is formed from an organization similar to a rolled centipede's. It is clear that she looks inhuman in the illustration, yet in the novel no one notices her identity as a monster until she removes the mask.

She also disguises her voice with that of a cute girl by using a leech that steals human victims' voice after killing them. Her original voice is harsh and grating, similar to that of Cocytus.

Personality
Entoma likes to eat humans, her favorite part being the muscular arm of men, though she doesn't mind what kind of person she eats if she is given an opportunity. If there are no humans to eat, she eats snacks called "green biscuits" instead. Despite treating humans as food, Entoma's nature is not considered extremely evil. If she comes across humans when she is sated and they do not bother her, she will ignore them rather than eat them. She doesn't like her original voice, so she becomes quiet when she loses her fake voice.

Background
Entoma Vasilissa Zeta was created by Genjiro 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.

The Maid Tea Party Arc
Entoma participated in the monthly Pleiades report and tea party. Yuri asked her to prepare the tea and the snacks. When Narberal reported her work with Ainz, she and her sisters got jealous of her closeness with Ainz. She also got jealous because all of her sisters got orders directly from Ainz. When she accidentally spilled blood in CZ2128’s drink, she was forced to drink it as a punishment. When Solution informed her favorite type of meat, Entoma asked if the quality of the meat really matters in considering the way Solution eats. She supported Solution's idea of asking Ainz to let them have one of the humans that are being interrogated while they're still alive.
