OS-tan InuT-tan from Green Lily is a whimsical figure that blends a chibi-cat aesthetic with high-tech detailing. The figure stands in a curious pose with one paw raised, her ears alert, and a tail curling around the base. The sculpt emphasizes soft, rounded lines for a friendly feel, contrasted by angular circuit-inspired patterns along the outfit and hair. Colorwork uses a cool palette of midnight blue, silver, and white accents to evoke a retro-futuristic OS vibe. Subtle shading enhances the panels and seams, while the glossy finish on the visor-like eyes gives a spark of life. The base is integrated and features tiny icons and glyphs reminiscent of system menus. Overall, InuT-tan communicates charm, loyalty to the OS-tan concept, and a playful energy that fits a collector's display shelf.

Within the OS-tan universe, InuT-tan is portrayed as the enthusiastic caretaker of a digital playground where programs learn to dream. Born from a quiet server room, she personifies the moment when an upgrade brings a new sense of self and purpose. InuT-tan travels between software and hardware, guiding novice users through routines with a wag of her tail and a reassuring purr. Her adventures emphasize loyalty, curiosity, and the idea that even a small mascot can influence the flow of data, inspire maintenance, and remind collectors that every byte has a story. In tales, she helps patch outdated memories, guards a friendship between two rival OS families, and celebrates the moment when a fragile icon becomes a trusted companion on a desk, lighting up the display with warmth and character.
