Chobits 20th Anniversary Edition, Volume 3 (Chobits 20th Anniversary Edition #49-72)

The more people Hideki talks to, the more he learns just how gray and complicated the line between humans and persocoms is. From his former boss, Ueda, to his coworker, Yumi, and his friend, Minoru, Hideki discovers that persocoms are so much more than convenient pieces of technology. With Chi missing, and her past just as mysterious as ever, Hideki finds himself questioning what Chi really is to him - a question he'll have to answer before it's too late.
