On planet Amoi, a great society has developed, creating a computerized city called Tanagura, ruled by supercomputer Jupiter. The populace is almost entirely male and is based on hair color; silver and/or blonds are the elitist, ending with dark/black haired as the bottom of society, often known as �mongrels�. Blondies keep �pets�, young boys kept for a few years, especially made for performing sexual actions for the Blondie�s voyeurism entertainment . Blondies aren�t suppose to keep pets for long or interact sexually with pets, but one blondie named Iason Mink has kept a pet named Rikki, for years and is rumored to sleep with him. Iason refuses to let go of Rikki, even with Jupiter�s disapproval. Rikki fights with his emotions and society problems, unable to decide what to do about his old friend/lover Gai (Guy) and their gang. Iason is obsessed with keeping Rikki, and Rikki doesn�t know what to do; fight against him or surrender to him.
