When Leah does kill Satan, he tells her that he's proud of her kindness and that he loved her dissimulating his love for not that demons kill her. Leah is left scared of herself after the Primordial War, but ten years later she manages to get through and during the time skip, Goddess, Alexandra, and Bruce help her see that she is not evil as Satan wanted her to be. Goddess reveals that Leah does possess the power to induce fear, but she can also grant determination to individuals when they are swallowed by their own barriers.
