Hideki discovers that his feelings intensify for Chi whether she is a persocom or not, despite other horrible experiences involving persocoms that happened to his friends. Chi becomes aware of her purpose through a picture book series called A City with No People which she finds in a bookstore.

The books speak about many different things involving human and persocom relationships: persocoms and their convenience towards people as friends and lovers, how there are things that they cannot do and questioning whether a relationship between a persocom and a human is really one sided. It also speaks about the Chobits series; that they are different from other persocoms, and what they are not capable of doing unlike other persocoms.

These picture books awaken Chi’s other self, her sibling Freya who is aware of their past and helps Chi realize what she must do when she decides who her “person just for me” is. Together, Chi and Hideki explore the relationship between humans and their new technological advantage, the persocom, as well as their friends’ and their own.

The series deals with issues and ideals of virginity, and sexual intercourse in that Chi is effectively incapable of sexual intercourse (in the manga and in the series), as attempting to do so would “reset” her, so she must therefore only entrust her body to someone who cares for her well-being as opposed to a purely sexual relationship.

Freya explicitly tells this to Hideki in the final scene of the manga, that to have Chi, pointing between her legs, means that Chi would lose all her memories. However, earlier in the story Freya makes elliptic statements suggesting that it could be possible to touch Chi there, as seen in Episode 20 of the anime when Chi was abducted.

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.
