Kaioh causes Kenshiro to fall into and underground chamber full of toxic gases designed to sap Kenshiro's ability to fight and attacks him. Meanwhile Hyoh rescues Lin from Samot, but covers her eyes so that she sees no-one. Kenshiro neutralizes Kaioh's ability to resist the toxic gases and they both leap from the chamber and their battle continues in earnest above ground. Kenshiro reveals to Kaioh that he is in fact descended from a branch of the Hokuto Söke bloodline based on what Kenshiro learned about its tragic history from the pillar in the Taiseiden temple.
