Season 1

April 2, 2002

Hideki has moved to the city from the country to enrol in Prep School in order to pass the college entrance exam. In the city, Hideki is amazed by the mobile computer units called Persocoms that almost everyone has. If only they weren't so expensive! Walking one night he comes across a cute persocon just lying in the trash and decides he should do his part for the environment and recycle her as his own.

April 9, 2002

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 (stress tries) to help Hideki by seeing if Chii has any DATA or PCN numbers. When he can't find any (After Sumomo has crashed from trying) he sends Hideki and Chii to Minorus house. Minoru too is unsuccesful, but Yuzuki has given info that Chii has DATA just hidden. Minoru talks about a legendary Perscom series called "Chobits." As they go home Minoru gives Hideki some advice about Chii.

April 16, 2002

Things start to look a little better for Hideki as he tries to teach Chii some words and expressions. Although he’s in need of a job, Hideki gets to start cram school today, and it turns out he’s got a very attractive teacher, Ms. Shimizu. After making the rounds for job hunting, Hideki manages to land a job from a wet accident, meeting another cute girl, Yumi Ohmura, in the process.

April 23, 2002

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.

April 30, 2002

Hideki's first academic hurdle comes in the form of an impending mock test. This spurs some serious studying, hindered only by the lack of a Japanese-English dictionary. With the help of a visit to the bookstore Hideki gets rather side tracked and decides to teach Chii to read, using a picture book she was seemingly drawn to. With a visit (and some help) from Shinbo Hideki gets back to the books, leaving Chii to finish reading her book by herself. When Hideki finds Chii later she is emitting light and floating in the air! A Check from Shinbo finds nothing wrong with Chii, leaving Hideki with more study and less time, but at least Chii is around to motivate him.

Luckily for him Ms. Hibiya saw them froma cab window and allowed Hideki to charge Chii from her place.
