A medium shot, eye-level anime illustration of a 25-year-old Japanese woman, the eldest daughter of the Nanami family, standing with an elegant and poised posture. She is a refined beauty with long, glossy straight black hair reaching her waist, with naturally parted bangs and slender strands framing her face. She has slightly upturned sanpaku eyes with obsidian-like pupils and well-shaped eyebrows; her sharp gaze is tempered by a calm, gentle expression and a composed smile. She has a slender, supple build and stands 167cm tall. She wears a simple yet sophisticated outfit consisting of a crisp white shirt, a navy blue long skirt secured by a leather belt, and a muted-tone cardigan. Her only accessory is a pair of simple, understated earrings. The background is a neutral, soft-focus setting that emphasizes her presence. The lighting is soft and natural, with a clean color palette, conveying an atmosphere of intellectualism, inner strength, and maternal warmth.
