A full-body, eye-level illustration depicts a young shark demi-human girl standing still by a classroom window in the quiet aftermath of school hours. She possesses a small, slender physique with pale, smooth skin and long, flowing silver hair that cascades down her back. Her face features large, slightly sleepy blue eyes with a blank, expressionless gaze, conveying a serene and melancholic mood. Distinctive shark-like dorsal fin ears protrude from the sides of her head, and a sleek, flexible shark tail extends behind her, curving gently. She wears an oversized student uniform, consisting of a baggy blazer with sleeves rolled up to reveal her slender arms, a large loose tie, and a pleated skirt. The setting is a traditional classroom, bathed in soft, natural light streaming through the window, illuminating dust motes in the air. The image is rendered in a high-quality anime style with delicate linework, soft shading, and a calm, tranquil atmosphere, emphasizing the character's ethereal and quiet presence.
