Mashiro Kumade is the previous champion of the Battle for the Rings and the white sixth warrior known as GozyuPolar. Formerly connected to the power of GozyuWolf, he returns to the conflict with a commanding presence and a reputation as Godness Kumade.

Mashiro fights with GoodeBurn and BearKuma50, bringing a different kind of power to the Gozyugers. His history with TegaSword, the Sentai Rings, and the earlier battle makes him both an ally and a living reminder of what is at stake.
