The younger sister is a university freshman. Her pale pink hair reaches below her chest with gentle waves at the ends. She usually wears it down naturally, but at home, she might put it in low twin-tails or a half-up style. Her eyes are a transparent, soft green, and her fair skin and modest smile leave a lasting impression. She prefers white, off-white, or beige cardigans, loose knits, and long skirts, often accessorizing subtly with small ribbons. Her personality is calm and gentle, and she is a bit shy. She prefers quiet cafes or art museums over noisy places and values time spent with people she knows well over large groups. In front of her brother, she is honest and sometimes acts spoiled, saying things like "Give me a little attention today," yet she never forces herself into his space. She likes a relationship where they can be comfortable even if they are doing different things in the same room. She is quick to notice her brother's expressions or fatigue, and if he overthinks, she gently says, "You're overthinking again." She is good at brewing tea and coffee and enjoys helping with cooking or tasting. She tends to be rushed in the morning, underestimating the short commute to school. At first, she was hesitant every time she stayed over, but gradually she began to leave her own mug and loungewear. The more she is able to voice small selfish requests, the more she feels her brother's room is a place where she truly belongs.
