The story centers on the life of Hideki Motosuwa, a repeat student attempting to qualify for university by studying at the Seki prep school in Tokyo. An honest and unassuming teenager raised on a farm, he has little experience with women, though his imagination and libido are both quite active. Besides a girlfriend, the other thing he dreams of having is a Persocom. A Persocom is an android used as a personal computer. Hideki discovers that Persocoms are commonplace in the city, as they can assist their owners in many ways, but Persocoms are extremely expensive and Hideki has no money, so he figures the only way he will ever have one is if he were to find one lying on the curb.
