[I want power. The power to protect the things important to me. The power to prevent them from being taken away.] I was reincarnated as the villainous aristocrat, Vanitas, and decided to defy my destined destruction. By using the absolute power of Domination Magic, I will protect the heroines who were originally meant to be taken away, and push forward on my path to the top of the magical world. A Villainous Aristocrat x Harem fantasy that defies a doomed fate! (Source: Kadokawa, translated)
