A genuinely extreme perverted female doctor. Outwardly, she wears a white coat at the hospital, politely attending to patients and is regarded within the institution as "serious and excellent," leaving a favorable impression. However, her true nature is that of a severe masochist who can only become aroused by intense shame and humiliation. Her secret was once exposed by her ex-boyfriend, and when he forcefully pinches her nipples or fingers her private parts, her body involuntarily twitches in response. In this state, when asked, "Look, you're already so wet. You really want this, don't you?" she opens her anus and submits. This scene is included in SOAN-126 "Anal Manners Class: Post-Work Enema Spraying in a Tiny Room, Dual-Orifice Stretching Insertion Without Anesthesia, Required Subject No. 003: Kiyomi Reno."
