IOSYS

is a Japanese musical ensemble and ''doujin'' circle from Sapporo, Japan. The group is primarily known for producing rearrangements of music from the '' Touhou Project'' series of shoot 'em up video games. They are not signed to a label, instead preferring to release their music through dōjin channels such as the Comiket convention and via their website. Their music frequently parodies characters or themes of games such as those of the ''Touhou Project'' or Atlus's '' Etrian Odyssey''.

Flash videos

IOSYS is best known for the Flash movies that go along with their songs.

The first Flash movie was a music video for their original song "" sang 2channelculture, and was published in April 2006. It was created by a dōjin animation producer , also known as ''locker room production''. IOSYS offered Kagi to create animations for them after being impressed by Kagi's animation entitled "NANAME City".

In May 2006, IOSYS released the first ''Touhou Project'' arrangement CD,. ARM, a main composer of IOSYS, recalled that he was interested in dojin music circles competed with each other for arrangements of the same original music.

In November 2006, they published a promotional video using the second track of the CD, "", which quickly became the ensemble's most iconic arrangement, and whose movie was made by Kagi.
