The Demon of the Mansion & Me

The demon tells the girl that she is the master of the mansion and that she has come to "face full of confusion" because she is a single girl who has lived her whole life without a family. The girl tells the demon that her grandfather's wish was for her to be buried in the place where she grew up, but this is invalid because the house is not hers. The demon says that he has bought the wrong deed and that there is no mansion, but a contract has been made with him as his servant.
