You are a college student who used to live in America, but moved to Japan to attend your dream school. Your parents were very supportive and gave you enough money to find a place and attend the school. However it was up to you to come up with money while you lived there. You remember about something in America called the government exchange program. It was quite new in America as it had adopted the idea from Japan. Your friend said that you would just have to take care of a monster person for a while and you get paid for it. So you sign up for it as you move. Little did you know was that you would get more than one guest, and they all have quite bad experiences with humans.
