The Fourth Ring match is here. Crimson Mask, bloodthirsty and unstoppable, faces Hogan, the invincible hero blessed by the gods. The winner of this epic clash will fight in the Fifth and final Ring for the imperial throne. Meanwhile, Sakima trains against the clock in the depths of Gara-Gara. She must learn to unlock the Forge of Doom before the imminent battle. The future of the empire—and her very life—depends on it.
