Ai no Kusabi

In the future on the planet Amoi, a supercomputer called Jupiter rules over a society dominated by men. The privileged light-haired elite are permitted to keep dark-haired outcasts-known as "mongrels"-as temporary pets. Iason, a member of the elite, finds a mongrel named Riki in the slums and brings him into his home. But when Iason keeps Riki longer than convention allows, whispers begin to spread about the true nature of their bond.
