Chi Goes On Errands
Hideki's a decent guy overall and realises it's a bit perverted to have his girl persocom running around the place with no underwear. Unfortunately, inexperienced as Hideki is, buying female undergarments holds a great source of embarrassment for him. Hearing about the dilemma Shinbo offers Sumomo's services as navigator and generally being a source of common sense for Chii, in order for her to go and buy her own underwear. This sounds like a great idea at the time, but causes a seemingly infinite amount of worry during the day at prep school for Hideki.

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.
