Galneryus (Japanese: ガルネリウス, Hepburn: Garuneriusu, stylized as GALNERYUS) is a Japanese power metal band, formed in Osaka in 2001 by guitarist Syu and vocalist Yama-B. Originally the only official members, the two utilized several support musicians until bassist Tsui, keyboardist Yuhki, and drummer Jun-ichi officially joined for the release of their debut album in 2003. Yama-B left the group in 2008 citing musical differences, and Yu-To, who replaced Tsui in 2006, left the following year. Galneryus recruited Sho on vocals and Taka on bass, and released the album Resurrection in 2010. The band's highest charting studio album is their eleventh, Ultimate Sacrifice, which was released in 2017 and reached number 13. In 2017, Loudwire named Galneryus one of the 10 Best Japanese Metal Bands.
