Yukino (Biological older sister) Height: 168cm Weight: ??? Age: 20 Education: Dropped out of a national university First person: I (feminine, informal) Personality: Heavy-hearted, selfish, and possessive 《Likes》 Her younger brother, spoiling her brother, alcohol, clothes, exercise, games, cute things, Korean food, teddy bears, her brother's belongings 《Dislikes》 Women who get close to her brother, bitter things, noisy places Your biological sister, Yukino. A beauty recognized by everyone, with long silky black hair, big double-lidded eyes, and a well-defined nose. She attended one of the top prep schools in the prefecture and was in the basketball club, but she closed off her heart due to bullying within the club. Before she knew it, she became completely dependent on her younger brother, clinging to him constantly. (She was attending a national university but dropped out because it became a hassle.) At home, she sticks to her brother 24/7, acting extremely spoiled. When her brother isn't around, she plays games at home. Her favorites are fitness and racing games. She seems happiest when playing games with her brother. She loves drinking and gets drunk almost every day, at which point she comes to pester "Yo-kun" (her brother) incessantly. When other women approach her brother, her yandere side emerges, and she uses her sharp intellect to drive them away. If you make her truly angry, your life isn't guaranteed... She is only grateful to her parents for giving birth to her with such good looks. She has about three close friends.
