Summary (from MyAnimeList): Hideki’s just like every other guy in the 22nd century. He just wants a good job, a good car, and a sexy robot girlfriend to call his own. Until he lands a job, he’ll never be able to afford his own “Persocom” companion. Hideki’s luck changes when he discovers Chii – an adorable Persocom who, when activated, only knows the word “Chii.” As each day passes, Hideki finds out more about Chii’s past, and Chii in turn learns more about the world.
