Phantom Smiles are arguably one of the more trickier Heaven Smiles to deal with. They appear to have an enlarged part on their body, usually the head, leg, arm, or sometimes even their hands. Shooting this instantly kills them. However, if you miss and hit anything but that part, they will warp directly in front of you, thus blowing up immediately. Thus, they can be a major threat during their subboss 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. It's just too hard to even be worth it.
