After failing the university entrance exam, Hideki Motosuwa decides to attend a tutoring course in Tokyo. He also looks for a part-time job to earn a little money. In this city, he discovers the “Persocoms”, personal computers in human form. One evening, the young man discovers an abandoned Persocom in a pile of garbage that looks like a beautiful girl. Fascinated, he decides to take it home with him and activates it. This Persocom only repeats the same gestures and can only say “Chii”. Hideki calls her that and gradually teaches her to speak. But maybe Chii is no ordinary computer? Maybe she is a Chobit, a persocom with a power beyond imagination?

Chii Awakens
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.

Chii 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 (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.
