This sensual Yaoi anime release follows the science fiction story of a world called Amoi, in which society is striated by hair color, and rules are enforced by an overlord computer. Though blonde people are at the top of Amoi's caste system, they are forbidden from participating in sexually indulgent activities, so when in the pleasure city of Midas, they keep "pet" adolescent boys for voyeuristic purposes. Usually, the boys are discarded after a year, but soon it becomes apparent that such rigid rules can't contain human nature forever.
