In the near future, personal computers take the form attractive women, called Persocons (editorial note: \"persocons\" actually means PC or personal computer in Japanese). Hideki Motosuwa is a poor student who failed his entrance exams to get into college. So, Hideki is forced to move to the city, get a job, and attend cram school in hopes of passing the next college entrance exam. He of course, wants a Persocon for himself, but is way too poor to afford one. One day, while passing a building, we finds a Persocon in a trash heap. However, his new find doesn\'t seem to be like the others he\'s heard about. She doesn\'t seem to have any operating system at all, and only says \"Chii\". As Hideki learns more about his Persocon (aptly named \"Chii\"), he finds that she is not of any known type, and most likely some sort of homemade model. He also learns of the rumor of the \"Chobits\", Persocons with the ability to think for themselves, instead of running only complex programs. Find out what happens between Hideki and his new Persocon, as she learns more about her environment, people, and life.
