So a little background on how this kayokyoku(the genre of music they sing) quartet came to be. Kazuyoshi Sakai who we know as Go-Gamego-Re aka Turtle Grongi and Sotaro/Gao Black was filming a indie project called Crusher Kazuyoshi in 2007 and during filming suffered an accident. He was hospitalized and one day had a dream regarding Hiroshi Uchiyamada and Cool Five, a kayokyoku group, and considered it as a sign. So he got Yujiro Shirakawa, Ryohei Odai, Shota Gogami, Tatsuya Hayashida, and Yusuke Tomoi to form Junretsu. Since then, they have been performing as a group since 2010 and Hayashida and Tomoi left mid-way leaving us with the current roster. Out of the members including ex-members as well, Odai was Shuichi Kitaoka/Kamen Rider Zolda in Ryuki, Shirakawa was Ikko Kasumi/Kabuto Raiger in Hurricanger, and Tomoi was Ryo Ashihara/Kamen Rider Gills in Agito. The group started promoting with the fact that some of them had a tokusatsu background but they outgrew it and they grew into a legit kayokyoku group, of course time to time busting out the tokusatsu card once in a while for the fans it seems.
