This is a remaster of C-chan's chibi fanart of Mac System 7-tan, an OS-tan originally created by his friend Aurora. The shading has been deepend to compliment the new random background applied to the image; her eyes and other facial features have also been modernized.

A former gangster and Windows 95-tan's main arch nemesis second to OS/2-tan, System 7-tan was defeated by her during the Consumer OS Wars of the mid-1990s. Since then she has entrenched herself in a chronic state of depression which has lasted long after the war and despite the Apple Family's steady reemergence as a world power. Although emotionless and non-chalant, she has had ample time to reconsider her life and has developed a calm composure both in her personal behavior and in her sword skills. It's not uncommon for her to regularly help out not only her sisters, but also the perverted OSX-kuns as well given she's impervious to their antics. The OSX-kuns (in kitten form) cameo in the above picture, protected by their "Onee-san".
