Shintarō and Tonbei follow the Fūma, using a trail of shuriken left by Oboro as markers. Aware of his sister's treachery, Kotarō uses a false trail of shuriken to drop Tonbei into some rapids, and then lures Shintarō, using Oboro as bait, to a small hut where he shuts him in and sets light to it. Then he heads for Hell Valley (Jigoku-dani). Searching for the Fire Tower, he encounters Shintarō and Tonbei whom he thought dead. Even though badly wounded by Shintarō, Kotarō finds the cave of the Fire Tower. By sheer force of will, he blows up the cave and himself and is buried together with the gold.
