When the Enemy of the World Becomes a Succubus

Due to a strange combination of circumstances, a wandering young man could only feed on blood and could only maintain his own magic power. It's just that the requirements for this blood are also extremely demanding, and he is also extremely picky, specializing in selecting great people in the entire continent. He has a bad character and extreme behavior. He often crawls and rolls on the bed of His Majesty, leaving dirty stains; he ruins His Excellency the Duke's garden so that petals fly everywhere, making it seem like no more flowers will grow; he always goes to bathe in the Son's bath, leaving holy water everywhere... All kinds of evil deeds are too numerous to describe. Until suddenly one day, everyone saw small devil horns growing on his head, a black tail with a heart, pupils that sometimes turned into heart shapes, and a succubus pattern on his waist. Only then did everyone realize that this nasty boy had turned into a succubus... Intention: To be added.
