In The Manga
The events in the manga proceed quite differently from the events in the anime. In the manga, Zima and Dita are agents not of The Syndicate, but rather the Japanese government, who know that the activation of Chi's program will result in the deletion of the person-recognition programs of every persocom in the world. As in the anime, Zima declines to inform Dita of Chi's location or level of program completion until Dita forcibly reads it from him. After Zima and Dita arrive at Hideki's apartment, a minor scuffle ensues between Dita and Chi, before Zima restrains Dita from attacking, wishing to see the outcome of Hideki's decision. Hideki confirms his love for Chi, only to find that Freya has taken control of Chi's body. Freya then explains to Hideki that he can never engage in sexual intercourse with Chi without formatting her systems, erasing everything that makes her a unique individual. Hideki states that he will love Chi regardless of this fact.
Freya then confirms that Chi and herself are indeed the legendary Chobits, but unlike the Chobits of legend, they are not truly sentient, nor do they possess emotions, but rather, they rely on the execution of software routines just like every other persocom. Even knowing this, Hideki says that he will still love Chi. Before relinquishing control of Chi's body, Freya asks Hideki if he would like to know what Chi's special ability is. Hideki declines the offer, and after imploring Hideki to take care of her sister, Freya vanishes and Chi awakens, embracing Hideki.
