Located in an upscale residential district of Kyoto, a certain obstetrics and gynecology clinic is rumored to conduct unusual examinations beyond standard medical procedures. Under the guise of "precision testing," patients are said to undergo illicit treatments while unconscious. The physician uses a vaginal speculum to excessively stretch the vaginal canal, conducting invasive internal inspections while deriving sexual pleasure from the act. These abnormal procedures are believed to cause severe physical and psychological harm, with many patients suffering in silence under this hidden abuse.
