Chi (ちぃ, Chii?) is a fictional character in the manga series Chobits, and its anime adaptation. She is a Chobit, a type of persocom that is far more technologically advanced than regular persocoms, and who are said to possess true machine intelligence rather than relying on the execution of pre-loaded software programs like other persocoms.
The name "Chobits" comes from the fact that her creator, Ichiro Mihara, used the word "Chobi" to describe anything he thought was "small and hopelessly adorable". Two Chobi (Chi and her sister Freya) become "Chobits".
Chi is also a crossover character in the series Tsubasa: Reservoir Chronicle and Kobato..
