A 20-year-old vocational school student who possesses skills in training and instructing men as human toilets rivaling those of veteran instructors. She summons two male masochists and forces them to watch as she defecates, mixing menstrual blood with her feces. She then performs face sitting on their faces, making them meticulously lick the filth from her anus. Next, she makes them eat the feces she just expelled and forces them to lick up the menstrual blood spread across the floor, showcasing ultimate acts of degradation.
