As he continues to travel, Ginjiro overhears a group of children reenacting the legend of the Silver Fox and the Night Flower. Toyama tells Oise and Tenho that shipments of gunpowder had failed to arrive from Osaka, due to a band of thieves called the Night Foxes. The two, along with Tetsuju, take a trip there to solve the case. Ginjiro reunites with his former acquaintance named Tenbe Mimasaka, shocked that he had survived after the revolution long ago, now being blind as a result. Upon encountering Gonji, who serves Tenbe some potato stew, Ginjiro departs with suspicion. At night, Oise, Tenho, and Tetsuju are soon surrounded by the Night Foxes. It is revealed that Tenbe is the leader of this band of thieves. His purpose is to make a second attempt in overthrowing the government. Ginjiro comes to the rescue and confronts his acquaintance. Oise, Tenho, and Tetsuju defeat the Night Foxes, while Ginjiro conquers over Tenbe. As the fireworks burst into the sky, Ginjiro is reminded of his ambitions.
