Lead vocalist and guitarist Takashi Yamaguchi first met drummer Yasufumi Kiuchi, at a university music club they were both members of. The duo ran into bassist Yoichi Kondo during February 2000, and the three went on to officially form the band now known as Sambomaster. They made their debut at a live house in Tokyo's Kōenji district and soon followed this up with the self-production of their first single "Kick no Oni" (Kicking Demons), which they spent nearly a year working on.
