Synopsis
On the planet Amoi, a highly advanced society has developed the computerized city of Tanagura, which is ruled by the supercomputer Jupiter. The population is almost entirely male and organized by hair color: those with silver or blond hair are the elite, while those with dark or black hair are at the bottom, often referred to as "mongrels." Blondies keep "pets"—young boys kept for a few years and specially trained to perform sexual acts for the Blondies' voyeuristic entertainment. Blondies are not supposed to keep pets for long or engage sexually with them, but one blondie named Iason Mink has kept a pet named Riki for years, and it is rumored that he sleeps with him. Iason refuses to let go of Riki, even with Jupiter's disapproval. Riki struggles with his emotions and societal issues, unable to decide what to do about his old friend and lover Gai (Guy) and their gang. Iason is obsessed with keeping Riki, and Riki does not know whether to fight him or give in.
