優雅 (Yuuga)
Yuuga started his career in a band named Diana as keyboardist, after that he joined a band named Celestier and was still fairly unknown. In 1999 he made a project named Chateau la tour which is where he got alot of his fame from. Yuuga is very known for his weird punk-rock visual kei style (that he calls "Ikare kei"), and also for destroying for other bands, and being a total douche. All of his bands have similar sound, and after Chateau la tour he formed Kar'Maria, and then DEViL KiTTY (his most famous band) in 2002. Deadly Sanctuary have very similar sound to DEViL KiTTY, but then again Yuuga wrote all music for Deadly Sanctuary. Besides this he have also had his own label named "Luciffer's records" which is where Deadly Sanctuary moved when CLIMAX ENTERPRISE got shut down.
To summarise it; Yuuga is a fairly known name in the indies visual kei scene.
