In 2005, Ishikawa asked Kazuumi to form a band. They were classmates in junior high school. Later, Hirose joined the band. He was a classmate of Ishikawa in
elementary school. Their first goal was to get the attention of the girls at a school festival. However, the festival was canceled due to a flu outbreak. Afterwards, they kept practicing to become good enough to get offers for
anime. In the beginning, their music wasn't popular due to the fact that they only pursued the music that they want to create, but they still became popular after some time. In recent years they have started playing
electronic music after learning how to use a
sequencer. The band have written songs for popular anime outside of Japan such as
Haikyu!!,
Dr. Stone, and
Gintama They experiment with genres like
techno,
ambient,
hip-hop, and
ethnic in their album material. They also performed the opening song of
Super HxEros anime. ==Discography==
