In the near future, personal computers take the form of attractive female androids, called Persocons.Motosuwa Hideki 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 would of course also like to own a Persocon, but is way too poor to afford one.One day, while returning home, he finds a Persocon in a trash heap. However, his new find does not seem to be like the others he has heard about. She does not seem to have an operating system at all, and only says "Chii". As Hideki learns more about his Persocon (aptly named Chii), he finds out that she is not of any known type, and is most likely some sort of home-made model. He also learns of a urban legend — the Chobits — Persocons with the ability to think for themselves, instead of just running complex programs.Find out what happens between Hideki and his new Persocon, as she learns more about her environment, people, and life.
