Using the attached character as the primary visual reference...

Prompt

Using the attached character as the primary visual reference anime girl, redesign her as a polished anime-style virtual mascot suitable for a 2.5D interactive web character system. Preserve her core identity and recognizable design: young adult anime woman, long black hair tied in a high ponytail with a dark navy bow, round black glasses, dark eyes, white long-sleeve school-style shirt, navy ribbon tie, navy pleated skirt, and the small “tokki” logo on her chest. She should feel intelligent, warm, slightly nerdy, friendly and expressive — like a study companion students would become emotionally attached to. Keep her cute and appealing without making her childish or overly sexualized. IMPORTANT: Design her specifically so she could later be rigged as a lightweight 2.5D interactive character similar in concept to a Live2D avatar. Her anatomy, clothing, hair and accessories must have clear visual separation suitable for independent layers and deformation. Show the character in a relaxed full-body neutral standing pose, facing mostly forward with a slight three-quarter angle. Arms should be naturally positioned and must NOT cover the torso or important clothing elements. Clean professional anime character design, high-quality linework, controlled cel shading, subtle highlights, expressive eyes, detailed but animation-friendly hair, clean clothing folds, consistent proportions. Do NOT include books, text, typography, furniture, props, scenery or additional characters. Plain light neutral background with strong silhouette separation. This is a CHARACTER DESIGN MASTER REFERENCE, not an illustration or poster. Prioritize character consistency, clean shapes, readable anatomy and suitability for future 2.5D animation.
