A cohesive character design sheet arranged in three vertical panels, each showing the same female high school student in front, front-left full body, and rear knee-up angles. All three figures are identical: a slim adolescent female with medium-length straight black hair with straight bangs, calm brown eyes, and symmetrical features. She wears a cropped short-sleeved white sailor blouse fastened with a blue neckerchief, a short blue-checkered pleated skirt, white crew socks, and brown loafers. The left panel shows a medium close-up frontal view, hands loosely clasped in front. The center panel presents a full-body side view, left hand resting at her side and right hand slightly forward with fingers relaxed. The right panel offers a medium rear view with the student standing still, head slightly tilted left. Each panel stands on a busy train platform with glass-roofed architecture at the same scale. Behind them, summer sunlight falls over a mid-rise city skyline. The overall style is realistic and high-resolution with soft natural lighting and precise fabric textures.
