95 OSR 2.1-tan

An extremely obscure OS-tan that originated from the 4-Koma series that introduced 95 OSR 2.5-tan although she was only mentioned but an actual character was made recently, appearing as a brown-haired girl with a bow in her hair like the other 95-tans but OSR 2.1-tan's bow is made of wires and cables and her shoulder-length hair is in a cyberpunk-ish hairstyle and she wears a steampunk-style outfit consisting of a black, grey + white dress with a pink bow and leggings, black steel-toed boots, brown leather gloves and belt, and a black kimono-style vest with a bronze OSR 2.1 brooch. Her steampunk appearance is meant to be high-tech looking as well as a tip back to the more old-fashioned 95-tan.

She is a sci-fi fanatic more interested in the future and introduced USB support to Windows, believing it to be the thing of the future and put previous interfaces in the past. However 95 OSR 2.1's USB support didn't work well. She moved away from the rest of the Windows family and now lives far away on her own, so far that one must write a letter just to ask a question. But she does regularly contact 95 OSR 2.5-tan.
