In the near future, personal computers take the form of toys figures, animals or even people, called Persocons. Hideki Motosuwa is a poor student who failed his entrance exams to get into college. Like everyone, he wants a Persocon for himself, but cannot afford one. One day, while passing a building, he finds a Persocon in a trash heap. However, his new find doesn't seem to be like the others he's heard about. As Hideki learns more about his Persocon, 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. What is this mysterious persocom and why was she in the trash?
