Though the human eye can not see it, there is a war happening, right under our noses. Angels versus demons for control of the earth, an epic unseen battle that only a certain clientele can experience. When people die in order to save someone against a demon holder and succeed, they are given the chance to become a Guardian Angel. Guardian Angels fight demons who invade the world taking over emotionally unstable humans. While this is their "job", each guardian is assigned to the person they saved to stay and live with on earth as a servant/warrior......

A knight from a kingdom long forgotten was tired of all the beasts, and so, he traveled to Yharnam. It was there he had the blood transfusion, and began his hunt. I plan to make this only about the Old Hunters DLC. Key word of course being plan, so it might change.
