Chobits is the story of an 18 year old boy named Motosuwa Hideki who grew up on a farm and wanted to go to college. But unfortunately, he was rejected, and so Hideki decides to go to a prep school so that he can study hard and get into college.

Then one night, as Hideki is walking home, he finds a Persocom (which is basically an android) in a dumpster. But, when he turns her on, all she can say is "chi". And thus begins the funny story of Chii and Hideki.
