Nightmare x Deathscythe: Resonance of Rebellion

Based on the erotic game by Guilty Nightmare Project, this OVA follows Rinne Natsume, a seemingly ordinary schoolgirl whose life is shattered when she uncovers a hidden truth about herself. Months earlier, a demonic cult attacked her family and murdered her father. During that harrowing ordeal, Rinne awakened the dormant power of a god of death residing within her, using it to strike down the cultists. However, her brief respite is short-lived, as she is soon captured and taken prisoner. Akuto, the leader of the cult's local branch, directs his deep-seated hatred toward Rinne, seeking vengeance for the wounds her father inflicted upon him before his death. Now trapped in the cult's grasp, Rinne is forced into a dark, sacred mating ritual between the demonic forces and her divine power. Hope arrives in the form of Setsuna Shindou and Yuuka, two wandering exorcists who intervene to rescue her. Yet despite their formidable skills and desperate efforts, the pair quickly find themselves overwhelmed and surrounded by a massive horde of devoted cult believers. As the situation grows increasingly dire, the fate of Rinne and her unlikely saviors hangs in the balance, leaving them to face whatever awaits at the end of this hopeless struggle.
