Phantom Smiles are a type of enemy in killer7 and arguably one of the trickier Heaven Smiles to deal with. One part of their body, usually the head, leg, arm, or sometimes even their hands, is enlarged; shooting this instantly kills them. However, if you miss and hit anything but that part, they will warp directly in front of you, blowing up immediately. Thus, they can be a major threat during their mini-boss appearance in Sunset Part 1. Using KAEDE Smith is the best tactic for the subboss appearance. However, it is possible to actually kill them before they blow up in your face, though this generally proves too difficult to justify the risk.
