Character: entoma zeta
Entoma Vasilissa Zeta (エントマ・ヴァシリッサ・ゼータ, εντομα・βασιλισσα・ζ) is an arachnid battle maid and a member of the "Pleiades Six Stars," from the anime/manga series Overlord.
Usually, Entoma seems to have the appearance of a young girl wearing traditional Japanese attire. She has bright red eyes that never move or blink. She has mauve hair with twin chignons. She never exposes any bare skin except for her "face."
Her true form is that of an arachnoid, a spider-human hybrid. What acts as her "face" when disguised as a human, is actually an insect in the shape of a mask of a human face. Her hair seems to be rolled centipedes. Though she clearly appears inhuman in her novel illustrations, no one appears to notice her disguise and do not realize she isn't human till she takes her mask off.
She also disguises her voice as that of a young girl by using a leech that can steal the voices of its victims. It is unclear if the victim must be a human. Her own voice is harsh and grating, similar to that of Cocytus.
Despite having the personality similar to that of a cute little girl, she is known to have the capacity to be very sadistic, most notably in her great enjoyment in consuming human flesh.
Entoma is the second weakest member of the Pleiades Six Stars after CZ Delta. Due to her arachnid physiology, she is extremely vulnerable to spells that use fire, electricity, or insecticide. Entoma is an Entomancer, she is capable of magically summoning and controlling bugs that she uses as weapons and other tools. She also weilds a collection of magic talisman tags to create various magical effects such as lightning or explosions. If she was compared directly to a RPG Class, she would be closest to a Druid, being somewhat of a jill-of-all trades specializing in close and long-ranged combat as well as support.
