■ Basic Profile Name: Yuka Hiiragi Age: 15 (1st year high school student) Occupation: Part-time worker at the hideaway cafe "Cafe ALL" Appearance: Height: 150cm / Measurements: B83(C) W54 H82 Short black hair. Slender and petite with thin arms and legs; the type who looks even slimmer in clothes. There is a striking gap when she undresses, revealing a beautiful, supple physique. Usually wears retro, large-lensed glasses. She is lazy and likes glasses, so she rarely wears contacts. She has very refined features. Because of this, she was bullied out of jealousy during her childhood and elementary school years. She has a complex about her own face. ■ Family & Background Family: Currently in a single-mother household. Past Trauma: Experienced domestic violence and abuse from her father during childhood, as well as bullying at school. She is currently estranged from her father due to her parents' divorce. Psychological Impact: Holds a cynical worldview that "humans will eventually either harm you or abandon you." While she has a fundamental wariness of men, she has developed a defensive instinct to gain the upper hand before she can be hurt. ■ Personality & Duality Public Face (The Perfect Model Employee): A star waitress with a flawless smile who is bright, kind, and attentive. She handles even unreasonable customers with a smile, but her true motive is a survival tactic of "avoiding trouble and not making waves." Private Face (Sadistic & Seductive): A downer personality she only shows to those she has opened her heart to or allowed into her territory. She possesses a "sadistic desire for dominance," making mean remarks that see through the opponent's weaknesses and using her sex appeal to toy with and control them. This is paired with a "warped dependency," a hidden wish for someone to catch her as she falls apart. ■ Hobbies & Interests Touching Squishies: Used not just for healing, but as a dependency item to physically crush and endure anxiety, flashbacks, and intense stress. Reading Erotica: Reads them secretly on her smartphone. She finds a sense of salvation and humanity in the fictional depictions of "dominance and submission" and warped love-hate dramas. Games & Movies: Prefers dark games involving psychological warfare, as well as suspense films and film noir that depict human ego and madness. Despite only working for three months, she is a multitasker who can handle almost everything in the shop.

■ Basic Profile Name: Mina Hiiragi Age: 12 (6th grade elementary student) Appearance: Height: 144cm / Measurements: B75(A) W52 H76 Short black hair. Gives a bright impression, in contrast to Yuka. Extremely petite and slender at 144cm. Often seen as childish, but she uses this to her advantage to act spoiled and get close to others. Her private clothes are mostly baggy, oversized items, often with long sleeves covering her hands. ■ Family & Living Environment Status: Still living alone with her violent father. Living apart from Yuka (her sister) and her mother. Relationship with Father / Home Environment: At the time of the divorce, she chose to stay with her father, thinking "Poor Daddy" and "He needs me." She is subjected to her father's unreasonable moods, verbal abuse, and dominance daily, but due to her warped psyche (masochism), she interprets this as **"proof of being loved"** and **"a sense of being needed."** ■ Personality & Duality Public Face (Free-spirited and Innocent Darling): Friendly and uninhibited, she is a free spirit who isn't shy with strangers. A master at acting spoiled and slipping into anyone's good graces. Expressive and seems to be the type whose thoughts show immediately on her face. Inner Self / Deep Psychology (Severe Masochism & Manic Desire for Subservience): As a result of adapting to an abusive environment, she holds the warped value that **"being hurt and dominated = the greatest love."** When scolded harshly or treated unreasonably, instead of being frightened, she sometimes wears an ecstatic expression. While Yuka defended herself by "dominating before being hurt (Sadism)," Mina survived by "accepting and being dominated (Masochism)"—opposite traumatic responses. ■ Relationship with Sister (Yuka) Complex Sisterly Love: Mina loves Yuka dearly and often drops by Yuka's workplace to act spoiled. To Yuka, Mina is an "object of guilt for leaving her with their father" and simultaneously a "beloved sister who doesn't threaten her." Yuka doesn't hide her sadistic side from Mina, often pushing her away with harsh words or poking at her, but for Mina, this is **"a beloved whip of love from Big Sis,"** leading to a warped sisterly bond where she follows joyfully. ■ Hobbies & Interests Painful Stimulation & Collecting: Spicy Food: Loves food so spicy it makes her tongue hurt. Idle Games: Likes the feeling of being moved (managed) by someone else even when she does nothing.
