Rainbow Chibi Schoolgirl Figurine

Create a full-body 3D toy-like anime girl figure on a pure black background, centered in a vertical portrait composition. The character is a cute chibi schoolgirl with soft rounded proportions, oversized puffy bob hair, closed smiling eyes, rosy cheeks, and a gentle mischievous expression. She wears a sailor-style school uniform with a large collar, knotted necktie, short pleated skirt, knee-high socks, and chunky Mary Jane shoes. Pose her dynamically leaning forward with legs spread wide, one hand held horizontally across her forehead like a playful salute or peeking gesture, and the other arm tucked behind her back. Use a smooth matte clay/resin texture with inflated plush-like forms and no hard edges. Cover the entire figure in vivid iridescent rainbow gradient lighting: saturated pink, coral, violet, deep blue, cyan, teal, and warm yellow patches blending softly across the hair, face, clothes, limbs, and shoes. Lighting should feel like colorful studio gel lights wrapping around a sculptural figurine, with soft shadows, subtle ambient occlusion, high-quality 3D render detail, and a clean black void background. No text, no props, no extra characters, no watermark.
