The Dark Lord in Another World

When Leon was one, his parents died of the plague. At eleven, his adoptive parents were killed one after another by heretics, and his hometown was razed in a massacre by a heretical cult. Still young, Leon and his sister Hannah were taken to an altar to serve as “food” for the evil god Lucifer. As he fought back, Hannah died, filling Leon’s heart with negative energy. This drew Lucifer into the world, and Leon gained dark powers, beginning a new life on the continent of Terra.
