Medium shot from a front view of a mysterious and youthful-looking girl standing in a school hallway. She has straight medium-length purple hair with inward-curling ends, cross-bangs, and a small ahoge; her eyes are black with distinct white pupils, reflecting a listless and lethargic expression. She is dressed in a school uniform consisting of a blazer with a ribbon, worn under an oversized, baggy black cardigan that hangs loosely off her frame. She stands still with her arms resting naturally at her sides, her posture conveying a sense of weariness. The background is a dimly lit school corridor with lockers and windows, rendered with a transparent, fragile quality. The visual style is soft and painterly with visible brush textures and layered color blocks, utilizing loose, sketch-like linework. A cool teal-blue atmosphere dominates the scene, contrasted by warm golden highlights, creating a transient and ephemeral mood.
