Kazuki is the older brother of Tomori, who in the past had been captured and tested on by scientists because of his ability to control air vibrations. Prior to this, he was going to sign with a major music label as a guitarist, and had been a very passionate fan of the band ZHIEND. He needs a medium-low male voice (NOTE: he will be doing a lot of crazy screaming, so you must be able to do that without clipping/peaking your mic).
