Riku

Riku is Shizu's loyal talking dog and only vassal, a white Samoyed who first appears beside him in the Land of Colosseum. Although his face naturally looks cheerful, he insists that appearance does not always match his feelings. Riku cares deeply about Shizu's welfare, remains beside him even when disagreeing with his plans, and often watches over children they encounter. He also appears to have a rivalry with Hermes.
