Nightmare x Deathscythe - Season 1

Natsume Rinne, a seemingly ordinary student, discovers a hidden truth about herself. She had been living a normal life until several months prior, when a demonic cult's attack resulted in her father's death. During that event, she awakened the Shinigami power latent within her and used it to exact revenge on the cult members. This period of calm is short-lived, as she is soon captured. Akuta, the leader of the local cult branch, directs his resentment toward Rinne, holding her responsible for the injuries inflicted by her father. The situation shifts with the arrival of two wandering exorcists, Shindo Setsuna and Yuuka. The outcome of this desperate scenario remains to be seen.
