A wide horizontal medium shot in a minimalist flat vector style, featuring a single adult female high school student reclining diagonally across a clean white canvas. The character is positioned with her head on the right and her feet extending toward the left, lying on her side with one arm folded beneath her head for support and the other resting naturally in front of her body; her legs are gently bent and placed together. She has a calm, slightly sarcastic expression with a subtle cold smirk, narrow sharp upturned eyes, and simple black-rimmed glasses, complemented by long straight black hair with blunt bangs. She wears a classic Japanese sailor uniform consisting of a white blouse, a black collar with thin white trim, a black ribbon, a black pleated skirt, white socks, and black leather loafers. The background is a restrained abstract composition of warm light-gray and beige geometric shapes, translucent circles, minimalist dot grids, and thin gray lines, all surrounded by a thin light-gray rectangular border. The visual style is characterized by flat color fills, consistent thin black outlines, a limited palette of white, black, and pale beige, and a strong use of negative space, evoking a sophisticated modern editorial poster.
