Shinbo discovered Hideki's new found treasure: PERSOCON CHII! After doing some check up, Sumomo got wrecked by Chii's mysterious CPU power, still, they found no data on Chii.
Shinbo recommended Hideki to Minoru kun, a persocon expert's house in order to get more info on Chii. After failing to detect Chii's info using ALL of Minoru's persocons, Minoru sat down with Hideki and told Hideki about the possible existence of CHOBITS, also known as persocons who can think and act on their own.
When Hideki was leaving Minoru's place, Minoru told him to never fall in love with a persocon, "you will never be happy…………."
