One night Hideki passes by a female persocom tied up naked in bandages and just laying there, seemingly thrown out. Once he realizes just how awesome his discovery is, he picks her up and carries her home. Unfortunately, Hideki is horrible with computers, so handling a persocom is even more difficult. After he finally finds the switch and activates her, Hideki finds himself in the presence of a persocom who can only say "chi". He names her Chi, and the rest is too spoiler-tastic to reveal.
