Hideki's feelings intensify for Chi regardless of her being a persocom and despite his friends' painful experiences involving other persocoms. 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 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 incapable 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 human beings and persocoms, as well as their friends' and their own.
