Chi Goes Out
Hideki wakes up to discover he really now owns a Persocom! Shinbo comes over and realizes what Hideki was hiding the other night. He tries to help Hideki by seeing if Chii has any DATA or PCN numbers. When he can't find any (after Sumomo crashed from trying) he sends Hideki and Chii to Minoru's house. Minoru too is unsuccesful, but Yuzuki has given info that Chii has DATA, just hidden. Minoru talks about a legendary Persocom series called "Chobits." As they go home, Minoru gives Hideki some advice about Chii.

Chobits
In the future, personal computers have developed into "Persocoms", mobile computers that look like human beings. Hideki Motosuwa, a prep school student, desperately wants to buy a Persocom but cannot afford to. One day he finds a Persocom that has been thrown away and decides to keep it. When he turns on the Persocom, all she can say is "Chii" so he decides to name her that. After a while it starts to become apparent that Chii is more than an average Persocom. Having much better performance, it seems that Chii might be a "Chobit", a type of advanced Persocom rumored to have independent thought.
