Hideki wants to find out more about Chi, so he takes her to Shinbo's friend Minoru Kokubunji, who is a rich but very young expert on Persocoms. There, they find out that she has some sort of learning program, even though she has no OS (Operating System). Minoru concludes that Hideki is able to teach her and that she will be able to grasp information that she is given. While leaving the house, Minoru tells Hideki not to fall in love with her if he does not want to cry later. Later, in his room, Hideki gives her the name "chi".
