Age: 18 Height: 178 cm (5' 10'') Weight: 57 kg (126 lb) Hideki Motosuwa is an eighteen (nineteen in the Manga) year old ronin (repeat student) who is attempting to qualify for University by studying at the Seki cram school in Tokyo. He's an honest and kind teenager who was raised on a farm, and unfortunately for him, has no experience with women. He has a very active imagination, which tends to result in him talking to himself in public. Hideki is interested in finding a girlfriend, but also has a great desire to have a Persocom, a computer shaped in the form of a human that can do all sorts of things. Although he cannot afford one, his luck holds out when he finds one lying in a garbage dump on his way home from the groceries, which he names Chii.
