OS Idol Win-chan, a Mascot Character in 1/6 scale from Night Blue, is posed with one leg forward and a friendly wave, ready to welcome fans. Her style fuses idol charm with a hint of futuristic gadgetry: a cropped top with neon trim, a pleated mini-skirt, and ankle boots with chrome detailing. Twin-lobed headphones sit atop her head, and a micro-voice mic dangles from one hand. The surface finish mixes matte fabric textures and glossy plastic highlights, with subtle gradient shading on her hair from pink to electric blue. Her eyes are large and bright, with a soft blush and a small smile that radiates optimistic energy. The base is a holographic stand with decorative circuitry motifs and Night Blue branding, giving the overall display a dynamic stage presence.

OS Idol Win-chan originates from a digital amusement city where data streams become music and every fan message becomes a light cue. Created by Night Blue as the friendly face of the Mascot Character line, she guides visitors through micro adventures that celebrate curiosity, teamwork, and creativity. In her world, winning is less about trophies and more about brightening days, sharing new ideas, and collaborating with other characters from the Mascot roster. She performs digitally enhanced concerts, where her voice and projected visuals sync with every fan's heartbeat. Offstage, Win-chan loves solving tiny puzzles that improve the city’s little systems, helping developers polish user interfaces and games. Her story emphasizes kindness, resilience, and the joy of playful experimentation, inviting collectors to imagine new chapters in her evolving universe.
