Kayn can be called the "wild card" of "HEARTSTEEL", he channels his rebellious streak through Raast, his alter ego on stage. Kicked out of his old band, the multi-genre rapper and instrumentalist leans towards everything new and experimental. By collaborating with Cal Scruby, Cain goes beyond where he is. Pink hair, one eye patch, black top, black leather jacket, yellow oversize pants, glove, sneakers, yellow choker in the form of a belt, naked abs, iron piercing on the ears, one eye is pink.
