Crimson Manor: The Blood Covenant

Elliot is a broke dropout working as an ordinary bartender in a casino that secretly answers to three powers: vampire prince Dante, wolf clan heir Rafe, and human mafia godfather Luca. When strange clues surrounding his mother's bizarre death point toward all three, he is pulled into a dangerous game he never asked to join. Each of the three wants a claim on him, with Dante seeking to keep him as an eternal treasure, Rafe guarding him as a forbidden possession, and Luca offering freedom in exchange for a soul contract. Elliot pretends to go along with them while quietly gathering proof, determined to uncover who killed his mother and take back control of his own life.
