IOSYS is a prolific doujin circle that specializes in music remixes, particularly vocal remixes of the background music from the Touhou Project series, with 33 albums (as well as several karaoke/alternate-remix and best-of albums and two re-releases) just dealing with Touhou in the past six years. Many of their vocal remixes have been given music videos by various artists. They also make plenty of original songs as well, including songs for rhythm games.

The group most likely got their name from the kernel file of MS-DOS (IO.SYS), which was used by every PC-98 machine.
