is a high school student and a very talented piano player. After winning the grand prize at a competition where a robot was the guest pianist, he decides to give up playing, since the robot played so well that he was moved by the performance. Like most other people, he treats robots and androids like appliances. He becomes curious of Sammy's activities when he notices that she comes and goes from the apartment at odd times. While reviewing her activity and GPS log, he finds an entry that says, "Are you enjoying the Time of EVE?" Retracing her steps, he discovers the cafe, Time of Eve, where humans and robots are treated as equals.
