Before Rin entered the world of Ridebacks, Tamayo was the Rideback princess. She is a skilled ridebacker and looks out for the good of her team. Tamayo and Rin are good friends as well as competitors. As well as Rin, Tamayo never gives up even if there is a little chance to win. Tamayo is the daughter of a highly respected political leader in Japan, who wants nothing to do with Ridebacks. However, she is interested in racing much more than in politics. That is why she ran away from home and does not maintain contact with her family anymore.
