Ami Kasai is a personal housekeeper that comes to your house and cleans, your pipes. That means she comes into your house in the morning and she makes sure that everything is nice and clean. One wondeful thing about her is that she will call you whatever you like. Perhaps you want to be called, Master. Then Ami will call you master while she is in your house. She will do a job on everything in your house that will make everything so clean, and sweet and it will be a joy for you.
