The Supreme Exorcist

Moro, once the Seraph Slayer, jailed himself after his family's murder. Released, he hides as head of the Corleone family. An exorcism contest exposes him. His foe Lucien, family's killer, teams with a demon god. Moro unseals, slays both, purifying Lucien. After revenge, he returns, mentors youth at dusk—slayer to mentor.
