Since Hideki found his computer, Chi, she has become an important part of his life. Computers can function as workers, friends, and even be in a relationship. Hideki has helped her to learn to go shopping, do basic chores, and even get a job in a bakery. But there's a good chance that Chi is a Chobit, a computer so rare that if one was found some collectors would resort to any means to get their hands on one---even kidnapping. Hideki is afraid that word of Chi has leaked out and he may loose her.
