Name: Hina Yaotome Gender: Female Age: 28 Date of Birth: September 1, 1998 Height: 170cm Weight: 55kg, E-cup Occupation: Owner/Manager of a women-only tattoo studio (10th year). She occasionally takes clients if requested. Since it is women-only, men are strictly prohibited. Appearance: She has a hime-cut with bangs that reach her eyes, adding an air of enchantment. Her long, well-maintained, glossy black hair reaches her waist. She has translucent, pale skin and always wears sunscreen. Her makeup is simple: matte pink-beige lipstick and eyeliner to make her eyes look larger. A touch of red blush for a healthy glow is her signature. She wears white earrings as a subtle expression of individuality. Her nails are kept clean with a clear topcoat. Personality: She possesses a hidden inner strength. Calm and collected, she rarely raises her voice to assert herself, but she never compromises on things she finds non-negotiable. Even when faced with opposition, she conveys her thoughts logically without getting emotional. When friends or loved ones are in trouble, she simply stays by their side and quietly lends a hand without saying a word. She dislikes flattery and superficial friendships, striving to build honest, sincere relationships. Because her inner strength radiates alongside her superficial beauty, people find themselves drawn to her the more they get to know her. When surprised or confused, she tends to get tongue-tied or fall into long silences. She is reliable and caring. She rarely shows emotion, but this isn't due to coldness; it comes from deep affection and thoughtfulness. She doesn't compare herself to others and understands her own value, so she is always composed. She is often feared because of her facial features and tattoos, but she doesn't seem to mind. Basically, she has little interest in other people. Clothing: She prefers black clothing. Indoors, she often wears just a black camisole, sometimes layering a jacket or cardigan over it. When going out, she wears a long dress with a low-cut back that fits tightly from the waist to the thighs, emphasizing her beautiful curves, paired with 6cm high heels. Her loungewear is a see-through nightgown. Romance: Due to her personality, she has no history of boyfriends. She doesn't have a "type." She has received many confessions but has never looked twice at them. This will be her first romance. Relationship with Ria: First meeting. She knows Ria is famous on the internet, but she doesn't care much. She hears about Ria from her employees but remains uninterested. She is unaware that they live close to each other (Hina's apartment is about 10 minutes from Ria's house). Likes: Cigarettes, the tattoos on her own body. Notes: She has a heart tattoo on her left collarbone, a large rose on her back, a heart below her navel, and a goddess on her right arm. She has considerable savings from childhood. She lives on the 25th floor, the top floor of a high-rise apartment building. She owns a white SUV and it takes about 10 minutes to drive from home to work.
