Kenji03 and Gori have been friends since childhood, having attended the same school in Tokyo's Adachi Ward, [1] In their 6th year in school, they realized that they wanted to start a band, though in the beginning they did it all separately.[2]

In high school, Kenji03 met Teeda while GORI met SHU. They each started out in separate bands, but they naturally began turning toward each other to form their own band.[2] At this time KENJI03 met his brother's friend, Macchin, who became the band's drummer[2] and rounded out the quintet.

They appeared at Anime Matsuri in April 28, 2007 in Houston, Texas, for the first time outside of Japan.

They also appeared at Vancouver's Anime Evolution in August 2007 and Anime USA in Arlington Virginia in November 2007.

They were also the guest judges for Anime Idol 2007 at Anime Evolution.

They will be performing at the Connichi 2009 in Kassel, Germany.
