OS Idol Win-chan is a bright and energetic mascot figure from the Mascot Character series by Cobra-Kai. The sculpture captures a dynamic stage pose, with Win-chan standing on one leg, microphone in hand raised high, the other arm extended toward the audience. The outfit blends anime idol flair with futuristic cyber touches: a short pleated skirt, a cropped jacket with shimmering panels, and knee-high boots with LED-like accents. The character has gradient hair that shifts from electric blue to vivid magenta, styled in twin tails that sway with the pose. The face features large expressive eyes and a cheerful smile, radiating stage presence. The figure uses a translucent plastic for energy accents around the wrist and microphone. The base is a round pedestal with the Mascot Character emblem, and subtle metallic paint highlights on the accessories give depth. Everything is crafted with clean lines, crisp paint, and sturdy joints for posing.
