My little devil

Sukiyaki hatsuo is a normal girl with a normal life except that she is named after a food.well that's what she tells herself. About a year ago her father was deathly sick and he was dying of a strange sickness she was still young so she had no idea of how to help her father, since he told her not to worry and that he was healthy. The day before his death he had given his soul to a devil in return he told the demon that he would have to protect and care for his daughter for the rest of her life the demon had agreed to the terms but would only meet her when she had turned 16, but suki had no idea that she would have a demon as a servant.
