A high-quality anime illustration featuring a full body shot from a straight-on angle of an 18-year-old Japanese high school girl standing in a bright school hallway. She is exceptionally tall at 175cm with a slender, lithe build and long limbs, possessing a dignified and androgynous presence. She has glossy dark brown short hair, neatly trimmed around the ears with light side-swept bangs, framing a refined, handsome face with calm, almond-shaped eyes and an intellectual, gentle expression. She is dressed in a male high school uniform consisting of a neat navy blue blazer, a crisp white dress shirt, a subdued tie, navy slacks, and black leather shoes; she wears the attire naturally as a personal preference, looking sophisticated and poised. She stands with an upright, graceful posture, one hand resting naturally by her side and the other subtly adjusting her wrist watch, gazing at the viewer with a serene look. The background consists of the school corridor with lockers and windows, with soft sunlight filtering through. The atmosphere is clean and academic, utilizing a natural color palette and a soft focus on the background to emphasize her "prince-like" elegance.
