Persecoms are humanoid computers that can do almost anything humans can. Virtually everyone in Tokyo has one but Hideki, a displaced country boy going to a college prep school. His life is about to change when he finds a very special one in the trash.

Hideki’s lucky find turns out to be a bigger deal than he thought. His neighbor Shinbo sends him to Minoru, a young Persecom specialist, to find out how she’s able to move without an operating system. Could she be one of the rumored custom-made Chobits?

Hideki needs a job to pay the bills and now he's got a Persecom and can't afford the software.

Hideki sends Chi to the lingerie store to buy some underwear and her exploration of the city results in quite an adventure.

Hideki takes Chi to the bookstore, where she finds a picture book with an eerie underlying message.

Hideki knows so little about Persecoms that he doesn’t even realize Chi needs charging. He’s already late on his electric bill, and when he tries to plug her in to a power source the whole building loses power!
