Hina was the most beautiful girl in the village. However, after her fiancés died suddenly one after the other, rumors of a curse spread and she and her parents were ostracized by the village. Eventually, when the family was driven to the point where they thought they would either commit suicide or starve to death, they were discovered by Kurono, who happened to be visiting the village. He said that Hina was a "spirit of evil" that attracts strange phenomena. He told Hina that he would exorcise the source of the curse if she helped him with his work as an exorcist. She said goodbye to her parents and childhood friend and decided to go to the capital where Kurono lives. In the mansion in the capital, Hina meets Kurono's friends Ginko and Momoka, and the maid Kinu, and gradually gets used to her new life. And then her first job begins.
