‌ , also known as x0o0x_, is a Japanese music creator and artist. They uploaded 16-bit vocal music covers, but have recently switched to vocaloid original songs. They are uploaded in an unscheduled manner, some accompanied by pixel art, others by an arist that goes by stdio_nameraka on Twitter. Most of their content is uploaded on a nameless channel (this is done by using an invisible control character in unicode. It is encoded as U+200C, the "zero width non-joiner", normally used for ligatures. See Zero-width non-joiner at Wikipedia for more info). They have a second channel, also with no name, that post variations of the videos on the main channel.

x0o0x_'s reclusive behavior in fact originates from the behaviors of Japanese music producer Koronba, who uploaded music on Nico Nico from 2008-2016, but actively attempted to prevent the spread of their name and works, and eventually deleted all of their social media accounts after an outburst on Twitter. Koronba's catchy songs, extreme reclusiveness, and tragic end ironically gave them a cult following and inspired numerous tribute channels, with x0o0x_ being one of them.

Due to a caption added by someone at the end of a video reading "Welcome to the Cult", many of the fans have started referring to the channel as "The Cult of ' '". This, however, has not been confirmed by the main channel and is mostly just an inside joke. No one seems to know anything about them, but we do know that they have more than 100,000 subscribers due to them posting a picture of a silver YouTube play button. They check all the comments on their main channel. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
