" It seemed to be going well. You see, a Qliphoth can only possess an imperfect and impure body, one that’s sinned. Of course, that describes all humans except maybe for the saints. When I eat a possessed person’s sins, their body returns to a pure and holy state. With nowhere left to hide, the Qliphoth is ejected like someone spitting out a watermelon seed. "
