A medium shot, eye-level anime illustration of a 25-year-old Japanese woman, the eldest daughter of the Nanami family, standing centrally with a poised and elegant posture. She has glossy, waist-length straight black hair tied into a single ponytail with natural bangs. Her face is characterized by sharp, slightly upturned sanpaku eyes with black pupils and well-defined eyebrows, giving her an intellectual and dignified appearance, yet she wears a soft, gentle smile of a kind older sister. Her makeup is sophisticated and natural, featuring light brown eyeshadow, a thin eyeliner, natural long lashes, a faint blush on her cheeks, and rose-pink lips. She is dressed in a high-quality, tailored lawyer's suit that exudes quiet luxury and prestige, complemented by small, elegant pearl earrings. The background is a simple, clean indoor setting that emphasizes her presence. The lighting is bright and clear, with a soft color palette and a polished finish, conveying an atmosphere of intelligence, grace, and inner strength.
