Summary

A man, trying to save money by living off from poverty, works at a convenience store where he encountered a ragged woman who wants a bentou (lunch box). She is, in fact, the goddess of poverty, but the man does not believe in her. To prove that she is one, she possessed him and now all of the man's savings are gone! What will happen between the two when the goddess will be staying at his place until he can pay them off?
