The souls of twelve girls were gathered together. They all had their own stories and came from different places. The heroine's soul was summoned to this party. She should have been sent to hell and she should be able to get some benefits from this party. However, her beloved actually appeared in this party. He is obviously not a real human being! The other girls came here with a purpose or were brought here for unknown reasons. Their stories will not stop because of the death of the girl, but will only be continued through their souls.
