This is one of the best VK bands, how could there be a worst member? Each member made Malice Mizer who they were, added their own piece to the music. Without Yu~Ki there would be no beautiful bass, without Kami there would of been no beautiful drums and a unique beauty to drummers, without Gackt/Klaha/Tetsu there would be no demanding vocals being sung, without Mana/Közi there would be no guitars to be heard. All of them tie into one bigger picture that is, Malice Mizer. Each member is just as great as the next. I could never pick/say a worst member. It is disrespectful.
