Shūsaku reveals the circumstances which have brought him to Edo (we learn he is 8 years old). Shintarō takes him to Keiko, Gorōta’s sister, for safe-keeping. The Black Ninja poison the well intending to kill Shintarō. One of the Black Ninja, Mosuke the Tiger, is caught by the police and secured in Denmacho Gaol from which no one has escaped. His companion, Gondayū the Shooting Star, and Gensai break him out but at the temple which is the Black Ninja’s hideout, Gondayū is suspicious that Mosuke would have been caught in the first place as he is too good. Sure enough, "Mosuke" turns out to be Tonbei in disguise. Gondayū uses a disappearing trick to escape and attack Shintarō who is coming to the temple. They fight and Gondayū is killed and Tonbei, who is tied to a tree outside is rescued.
