When the World's Public Enemy Becomes a Succubus

Through a twist of fate, a wandering boy can only feed on blood, and must rely on it to sustain his magic. But the blood he needs is extremely particular, and so is he: he picks only the most remarkable people on the entire continent. He has a foul personality and takes things to extremes. He often climbs into the Crown Prince's bed and rolls around, leaving filthy stains behind; trashes the Duke's garden until flower petals are flying everywhere, as if no flowers will ever grow there again; and regularly goes to bathe in the Saint's bath, splashing holy water everywhere... His misdeeds are too numerous to count.

Then one day, everyone saw little devil horns sprouting from his head, along with a black tail tipped with a heart, pupils that sometimes turned heart-shaped, and the succubus mark at his waist. Only then did they realize that the wicked boy had become a succubus...
