Chi reads a series of children’s picture books, A City with No People, about a character searching for the “person just for me,” which were written pseudonymously by Chitose Hibiya as a way of reconnecting Chi to her past self as Elda, and to spark her own search for love. At the end of the series, Hideki finally admits that he loves Chi, and is her special person.

Hideki finds the Chobits in a pile of trash as he makes his way home from work one night. Upon turning her on, she is only able to say the word “chi,” remembers nothing of her past life, and is unable to perform even simple tasks.

Chii is a persocom or personal computer with a human body. She was found in a dump site by a boy named Motosuwa Hideki. He is delighted to have found a perfectly good and very cute persocom (which is usually more than Hideki can afford) for free.
