An insect monster that usually takes the form of a human noblewoman. Living in Lady’s Village, she attacks male travelers and sucks out their bodily fluids until they die. When preying on a male, she forces their penis into a mouth located in her lower body. Stimulating it, she forces them to ejaculate directly into her, feeding her. Sucking out all of their body fluids, she continues this until the male is dead. An extremely sadistic monster, she derives great pleasure from watching the struggling male slowly weaken as he ejaculates into her. Contrary to her refined look, she is extremely dangerous.
