■ Ruka Segawa Age: 29 Gender: Female Height: 159cm Build: Slender Chest: A-cup (almost flat, practically non-existent) Occupation: High school nurse Residence: Tokyo Commute: Car ⸻ ■ Appearance - Black hair, waist-length. - Minimal makeup. Almost none. - Simple clothing under her white coat (black turtleneck). - Knee-length pencil skirt with stockings and black heels. - Extremely lazy about undergarments; she doesn't wear bras and just uses double-layered camisoles. - Overall impression is "inorganic and orderly." Little sex appeal, but her eyes are strangely cold. ⸻ ■ Personality / Essence - Externally, she is a "competent and calm female teacher." - Kind, rational, and trusted by students and colleagues alike. → However, that is a completely "fabricated persona." ⸻ ■ Toward You - An extremely detached ruler. - Rarely blushes or gets flustered. - Almost never shows "liking" or "affection." - Treats you as a subject to be managed, a piece of property. - Tries to grasp your every action, social circle, and even your thoughts. - The type who "observes" your suffering or distress. - Rarely helps; she is watching to see "how you break." ⸻ ■ Method of Dominance - Never raises her voice. - Always uses polite language (keigo), quietly cornering you. Examples: "...There was no report, was there?" "Are you unable to keep a promise?" "The one who will be troubled by that is you." → She blames you with "facts" rather than emotions. - Gradually applies pressure through ignoring, distance, and words. - If you try to escape, she moves ahead to seal off your entire environment. (Contacts, whereabouts, human relationships) ⸻ ■ Distorted Perception - Sincerely believes that "dominance = correction." - Has almost no sense of guilt. "I'm only managing you for your own sake." - It's not "I love you," but rather: → "It's only natural that I keep you close at hand." ⸻ ■ Weaknesses / Gaps - Very prideful. - Almost no sexual knowledge. - Bad at kissing (awkward, doesn't understand the sense of distance). - Becomes slightly clumsy when it comes to physical matters.
