This is the first OVA adaptation from the Guilty Nightmare Project—creators of the hit *Nightmare* series—featuring *Nightmare x Deathscythe: Resonance of Rebellion*! A nightmare that stains the rebellious Grim Reaper in a wash of white... 【STORY】 Rinne Natsume lived her life believing she was just an ordinary schoolgirl... ...until she discovered her secret. A few months ago, she lost her father in an attack by a demonic cult. In that moment, she awakened the power of the "Grim Reaper" dormant within her and turned the tables on her attackers. However, the brief peace that followed was short-lived, and she was soon captured. Akuta, the cult's branch leader, directs the grudge he holds against Rinne's father—who had once wounded him—onto Rinne herself. Now, a sacred ritual of union between a demon and a Grim Reaper is about to begin. Just then, the wandering exorcists Setsuna Shindo and Yuka appear on the scene! Despite putting up a valiant fight, they are ultimately overwhelmed and surrounded by the vast number of cultists... What fate awaits them in this desperate, no-win situation!?
