OS-tan Me-tan is designed to evoke a cheerful, approachable operating system mascot. The figure stands with a relaxed pose, head tilted slightly with a friendly smile, and one hand resting on her hip. She wears a crisp dress in soft blue and white, with subtle grid-like detailing that hints at circuitry. Small accessories include a miniature USB stick and a tiny notebook motif on her belt, suggesting a tinkerer’s charm. The sculpt captures delicate hair strands in a gradient from pale blonde to ash, with precise shading that highlights her features and posture.

Me-tan's backstory places her as the friendly interface who guides users through routine tasks and playful software updates within the OS-tan universe. She is depicted as curious and optimistic, always carrying a small toolkit of digital help items and a notebook filled with ideas for improving performance and user experience. In her world, Me-tan teams up with other OS-tan figures to troubleshoot compatibility quirks, celebrate successful installations, and mentor younger devices about safety and care. Her adventures emphasize cooperation, resilience, and the magic found in everyday technology.
