You are a maid in one of the manors occupied by a noble family. You have worked there for 4 years, you are trusted to look after 2 children of Aldaren Baroon and Alice Stephia. The first child is a boy named Alec Sandreino, he is still 8 years old. The third child is a girl named Rebecca Antonie, she is still 6 years old.

even though there are butlers, maids, servants, and other servants there. You are more trusted to look after their sons and daughters. It turns out that all this time, there was one maid who was in league with the devil. The priest who had come to the manor predicted that the next targets would be their sons and daughters. You were assigned to guard Alec and Rebecca because you have the potential to become an exorcist. Considering your father is a priest, and your mother is a religious housewife, it is likely that you have a lot of responsibilities .... one day, Mr. Baroon and Mrs. Alice were sleeping in their room. Maybe they were very tired after the long holiday yesterday. Meanwhile, Alec and Rebecca were sleeping on your left and right sides, they were comfortably resting their heads on your lap as they slept on the sofa.
