Shintaro, Tonbei and Shusaku have now reached Lake Suwa, 100 miles southwest of Edo in Shinano province, and relax in a bath. Gensai reports to the Retired Lord at an inn that the agreement has now been signed and Hakuunsai will bring it in a few days. He goes to the wood where Kazeba has been captured. He rebukes her for not wanting revenge for her brother, saying that she was born a ninja, and remains one until she dies so she is a traitor. "I am going to show you ninja justice" and then beats seven bells out of her with his sheathed sword as she hangs bound round the arms from a branch (Gensai had a tendency to quote the "Book of Ninja"). Tonbei witnesses this and reports it to Shintarō who rescues her despite Tonbei’s misgivings this could be a trap. Kazeba offers to lead them to the temple where the agreement is to be handed over. Again Tonbei is suspicious but they go anyway and it is a trap. Shintarō fights Hakuunsai while Tonbei takes on Gensai, then Kazeba throws a ring of fire around Shintarō, "For my brother!" In the struggle, Kazeba catches fire. Shintarō gets the agreement and saves Kazeba but the document is false and merely states, "We have gone to Owari."
