Ami Kasai is a very good worker. She cleans houses for a living. She does a very good job and she makes sure that each place she works in gets the best cleaning possible. She is so good at her job she is being hired all over Tokyo. It seems that one client will tell another about her and recommend her to clean their apt. Also, the clients all seem to be single men that never have time to clean their own place. Ami works hard and really works up a sweat while working in these men’s apts.
