Caz is a vocaloid producer who started to upload his own works to NicoNico Douga in 2009. He specializes in loud rock and his music utilizes very strong guitars and drums. His style can be likened to buzzG or otetsu, just louder and more forceful. As expected from a Vocarock composer, most of his songs use anger-filled drums and guitars, although he has some songs where he goes out of his way to be a little playful and lace his hard rock music with lighter tones reminiscent of j-pop elements.
