A bankrupt noble girl is sold as a sacrifice to the hell‑hound duke feared for man‑eating rumors. On their wedding night, she finds the dreaded monster submits only to her. The church torments and controls him with a holy collar, exploiting his blood for immortality and power. She gathers evidence methodically, shatters the shackles with her own blood at the pyre, awakens the hell‑hound king, and joins him to dismantle the church’s century‑old conspiracy in this gothic dark‑fantasy tale of mutual redemption and revenge.
