Hideki has moved to the city from the country to enrol in Cram School in order to pass the college entrance exam.

In the city, Hideki is amazed by the mobile computer units called Persocons 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.

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 Chi has any DATA or PCN numbers. When he can't find any (After Sumomo has crashed from trying) he sends Hideki and Chi to Minorus house. Minoru too is unsuccesful, but Yuzuki has given info that Chi has DATA just hidden.

Minoru talks about a legendary Perscom series called "Chobits."

As they go home Minoru gives Hideki some advice about Chi.

Yoko Okino is one of the brightest stars in the entertainment industry. But her previously spotless record takes a hit as a body is discovered in her penthouse apartment. With no other suspects to be found and all clues pointing to the grief stricken star, Conan and Richard, Yoko's number one fan, struggle to find the one clue that would clear the idol's name.

Chii isn't feeling like herself and basically collapses in Hideki's apartment. He gets an adapter from Shinbo but unfortunately can't recharge Chii due to the fact that he never paid his electric bill.

He struggles to find a building to recharge Chii but falls when climbing a wall to a building which is open til 2am. Luckily for him Ms. Hibiya saw them froma cab window and allowed Hideki to charge Chii from her place. Shinbo arrives and informs Hideki and Ms. Hibiya of how many watts are being used to recharge Chii. Hideki exclaims that he will pay her back for both the electricity used and his rent even if it kills him.

With Hideki broke, Chii decides that she wants to find a job to get money to give to Hideki. Hideki has little objection, but stipulates that Chii must find a "good job" to work at. Unfortunately for Chii, someone with a very bad job for Chii, finds her while she's out and tells her the job he has on offer is a "very good job".

After Chii's reboot button is pushed, she escapes the 'peep show' room and is jumping around the city disabling all persocoms. She finally exhausts herself and Hideki catches her before she falls off a railing. Chii gets a job at a bakery having a five year anniversary thanks to Hideki. The manager offers Chii a permanent job which she accepts only if Hideki allows it. She trys to give Hideki her payment but he refuses telling her that since she worked and earned it, it belongs to her and for her to buy her favorite things (whatever they may be).
