Kyouka first started as the vocalist of several minor local acts in the mid-90's in the Kansai area. During his days in au†ism, he was spotted by the visual kei independent label KEY PARTY and invited to move to Tokyo and start a new project. au†ism then changed name to Aliene Ma'riage and became one of the most succesful acts in the independent scene.
As Aliene Ma'riage went downhill and announced their disbandment, Kyouka released a solo mini-album in 2001 and formed the session band Cupid with former labelmates and roadies. In 2003 he came back with a new project called Chaos System. The band kept playing gigs for a couple of years had to cease activities after all founding members except Kyouka left.
In 2006 Kyouka reunited with friends from his KEY PARTY days TOMO (ex-DEFLOWER) and Aya (ex-Missalina Rei) and formed Deflina Ma'riage as a limited-time project. They were supported by TOMO's label THIRTEEN MUSIC and seemed to gather more attention than the members' previous efforts after KEY PARTY. In the meantime Kyouka also played in the session band Native Devil while recruiting for members to resume Chaos System activities, but all members left again after a few months of gigs in 2007.
After about a year playing in session bands, Chaos System resumed activities again in December 2009 with a new lineup including Deflina Ma'riage guitarist TOMO. The band got signed to TOMO's label and had a couple of releases, but disbanded in about a year citing musical differences.
In early 2011 Kyouka, who could get exposure again thanks to a short revival of Aliene Ma'riage, started the unit DROSERA OBLAAT. with former Chaos System member Makoto, but disbandment was announced in less than six months. Kyouka announced he had no interest in joining bands again, and showed interest in starting a solo career instead. He then started playing in session bands again in 2012, and was eventually invited by ex-DAS:VASSER bassist Hideaki to start a project together. Insanity Injection preparations started in 2013 while the two were playing in the long lasting session band Pink-Tribal, which kept holding gigs until the end of 2014. After a year of silence, Insanity Injection information was disclosed in December 2015 and the band officially debuted in February the following year.
