Hesenberg Foundation

This is an old bachelor in the archaeological circle. Due to an accident, he traveled a hundred years and came to medieval Europe to participate in overthrowing the rule of the vampire elders. In the process, the vampire's curse was actually broken... And a child was born. Since then, it has become the object of competition among major families. The protagonist and the harem beauties fight all the way and finally ascend to the "Pale Throne". And the first person to become the King of Vampires, yes. It's a human being!
