Meanwhile, Sahei and Sayo come across the limbless torso of Iemon who still wants to pursue his dream of conquest as a genma. He offers Sahei a place at his side, but Sahei poisons him instead. Sayo finds Musashi and convinces him to fight as a human, and as she leaves, the entire mine site collapses from the force of the battle. Later, the head monk at the temple finds the Oni gauntlet returned, but appears to be heavier than before.
