Caste: Mongrel Occupation: Gang member Riki has been called the 'Charisma' of the slums. He was the leader of Bison, a gang in Ceres, before he fell in with Iason and became his pet. Riki is proud, fierce and defiant, though his experiences change him and some in the slums feel he has lost his spark. He is torn between his pride and the feelings he has for Iason that he is unwilling to acknowledge. (Source: Tanagura An Ai No Kusabi Fanlisting)
