Players assume the role of private eye Kyo Saeki, a former police detective who's left the force to go into business for himself. The detective is a big fan of video games, and loves spending time at the local arcade (called "Spot 31") practicing his skills in the latest fighting games. He's also got a weakness for life's vices, such as drinking, smoking, gambling, and of course, women.

One day, a young woman visits his office requesting that he take on her case. The crime? A painting belonging to her late father has gone missing, likely stolen by her step-mother. The hero must solve his client's family mystery by gleaning clues through romantic encounters with women in town.
