[A changing room before a Halloween event, full of female cosplayers of all different sorts, was struck by lightning! Every one of them has turned into ghost-like creatures, and they now act exactly like the characters they were cosplaying. And they have one goal... you.]

But not floating floating, but as if the person wearing them was invisible. You can almost make out the outline of their busty figures. They all seem to slowly turn towards you...
