"ノンジャンィジュァル" is a Japanese visual rock band, (ヴィジムム) The visual department is an orchestra developed from Japanese rock. The name "visual department" has nothing to do with any music type, but is used to refer to bands with exaggerated costumes and makeup. Because the visual system focuses on visual style, it is a type of orchestra rather than a type of music. Most visual orchestras take the route of Japanese rock, pop music or light rock. However, we can still see that some orchestras take the music routes of heavy metal, industrial rock, Synth Pop, punk and so on. On a large scale, most visual orchestras take some kind of "rock music" route.
