Tanaka (birth name unknown) was born in Yokohama, Japan, and went to school in the same area. He first became interested in releasing music in junior high school, and began uploading songs on the Japanese video streaming service Nico Nico under the moniker from February 2012, at the age of 14.

After becoming friends, Vacon inspired Boku no Lyric no BÃ Âyomi to try releasing original rap songs. In late 2012, he uploaded his first rap song, "One Night Stand and Rain". He decided on his stage name late at night while uploading the song, arbitrarily choosing the phrase . He felt that his voice while rapping sounded as if he were singing in a monotone instead of rapping, so decided on the name because of this. Originally he wanted to form a band, however did not have any friends who wanted to join in. As a student at an elite high school, he found that his friends had little interest in music, so he decided to release music as a solo act.
