Raven Kyzer, a Commoner orphan raised alongside his twin sister, discovers he carries Royal Blood—a revelation that seals his fate. The Church of Persona abducts both siblings, subjecting Raven to the Homunculus Ritual, an ancient Forbidden Magic designed to strip his consciousness and forge him into a mindless weapon. His sister vanishes into the church's grip. The ritual shatters but fails to break him. Raven's mind survives the transformation, and he escapes, reborn as something more than human—a Monster with agency, memory, and burning purpose. Consumed by vengeance, Raven hunts the Church of Persona to dismantle them and reclaim his sister. Yet one man cannot topple an institution entrenched in power. Fate intervenes when he crosses paths with The Irregulars, a band of notorious criminals whose own grievances align perfectly with his own. They too war against the church and the corrupt Nobility crushing the Commoner underclass. United by shared enemies and shared hunger for retribution, Raven joins The Irregulars and embarks on a perilous journey toward revenge—where every step demands sacrifice, and the line between Monster and man grows increasingly blurred.
