The world is now controlled by the demons and monsters of darkness. The humans lost, and now they were sold as slaves to the creatures of the night. Same goes with the Utunium sisters. They were captured, and now are being auction to the highest bidder. Unfortunately for them, the highest bidders were the princes of vampires themselves. The Rowdyruff boys, the sons of Mojo Jojo and the cruelest vampires to be sold to. Or so they thought. Will they somehow escape them, or will they forever be slaves to their vampire masters?
