Chi is an android character from the Chobits manga/anime series. She is a persocom - a type of android computer created to serve their owner by performing simple to complex activities - ala Bicentennial Man.
Fortunately, Chi is not just any regular persocom, she has super advance A.I. that enables her to feel and learn new tasks without installing additional software - these types of unique persocoms are known as Chobits.
This Chi / Chobits papercraft is from designer Alclione, great work on the hair and dress btw.
