the image is definitely based on the victims perception and tastes towards the singer.kinda curious what the charm illusion bases itself on. Is it the victim's conception of irresistible or is it the singer's conception? It's hard to say without going back to the beach arc for reference but I think the seductive illusion might have been PLUMPER around the middle than her usual self. Which has some interesting implications if it's based on the victim's preferences...
Obviously, it eliminates the competition, but still.
