Man with a Mission is a Japanese rock band affiliated with Sony Music Records formed in Shibuya. They are popularly known for the wolf masks they wear in their concerts and music videos to the point of being called a wolf band.
In the cover of the band's backstory, Man with a Mission's reason for the wolf masks is because they were created as the "Ultimate Lifeform" by Jimi Hendrix (who in this story is described as being a doctor of the guitar and a wolf biologist).
Renowned mangaka, Go Nagai helped in designing the artwork for one of Man with a Mission's albums. In return, one of Nagai's iconic characters Devilman starred in the music video for their single "When My Devil Rises" battling against enemies such as Sirene and Zennon.
