Akuma wa Rosario ni Kiss wa Suru

A boy named Yukihiko has a soul that attracts demons, a condition known as a "sacrificial soul." Since childhood, he has seen supernatural creatures, which he believed to be ghosts. These beings, however, are demons that bring misfortune and death to those they affect. Despite wanting a normal life with friends and a romantic relationship, Yukihiko often causes trouble and unhappiness for those around him. After encountering a particularly dangerous demon, he flees and meets a nun named Alicia in a church. He agrees to a contract with her to eliminate the demons haunting him. Unbeknownst to him, Alicia is actually a demon with ambitions to become the Demon Lord.
