The Dark History of the Reincarnated Villainess, Vol. 13 (manga)

Sol won't give up. The Knights of Schwartz won't stop. So in order to protect both her beloved character and the world of her Dark History, Iana takes up the mantle of the Demon King--at least for now--to assist in the Knights in their quest to maintain the plotline at all costs! But traveling with Konoha and the others as their guide in the guise of Pervert Mask is a double-edged sword. If anyone finds out her true identity, it could mean her death...and the end of the world!!
