XOVER started in 2009 as a project of Kouichi, former guitarist of Laputa, and Shaura, who leads a solo career under his other stage name, Juka.
Their music was not as influenced by electronic sounds as it was in Kouichi's solo project, Everlasting-K. Together with Shaura's voice, the songs created by this duo consist of melodic rock tunes in typical visual kei style.
