From MangaHelpers:

A girl is moving into an apartment where she'll be living alone and going to school. When she arrives, though, there is a very small maid already there! It turns out that the small maid is actually a tanuki, who is determined to repay her debt to the girl and her father for feeding her when she was hungry. However, the tanuki doesn't appear to be able to do anything at all useful! Her biggest appeal to the girl seems to be how cute she is in her raccoon form. Now the girl begins her life of part-time work, school, and living with a tanuki! [tethysdust]
