OS-tan - InuT-tan is a petite, dynamic figure that embodies the playful blend of tech and charm. The character features soft, rounded proportions, with long dog-ear shaped hair ribbons and a tail that curves into a USB-like plug at the tip. She wears a mini outfit inspired by OS interfaces: a crisp white bodice with light blue trim, a translucent teal cape that resembles a live wallpaper, and little boots with pixelated stitching. The sculpt highlights fur texture on the ears and tail, and the eyes are large, glossy, and bright, conveying curiosity and loyalty. The base is a stylized OS startup screen, with subtle icons and a soft glow. Paintwork emphasizes gradient shading across her hair and clothing, with metallic silver accents on hardware-inspired details. The overall impression is cute yet tech-flavored, suitable for shelf display and cosplay photography.
