In a medium shot from a front-facing angle, a mature high school girl stands centered within a quiet classroom. She has a small face with a neutral, expressionless gaze, characterized by sharp, almond-shaped sky-blue eyes and thin, pale pink lips. Her fluffy medium-length hair is grey with distinct blue inner color highlights. She wears subtle makeup and has numerous piercings decorating both ears. She is dressed in a neat school uniform, standing still with her hands resting naturally at her sides. The background consists of a classroom setting with desks and chairs, rendered with soft, out-of-focus details. The visual style is a painterly anime illustration blending soft oil-like textures with luminous watercolor light, featuring broad, airy brushstrokes, gentle motion blur, and natural color bleeding that creates a serene and sophisticated atmosphere.
