Characters
- Tatsugoro 
- Head of the Megumi fire brigade in charge of Hamamatsucho. He is masculine but sensitive to the ways of society. His nominal resistance to his wife’s demand for action stems from his desire to find the optimal timing for the revenge to minimize the inconvenience to his family and troupe. 
- Yotsuguruma Daihachi 
- Modeled after an actual sumo wrestler who lived at the end of the Edo Period. He was much admired by his fellow wrestlers and a key figure in the perennial conflict with firefighters. He had two samurai patrons. 
- Onaka 
- Tatsugoro’s wife. As competitive as a man, she threatens to break up with Tatsugoro if he does not take on the challenge by the sumo wrestlers. 
- Matahachi 
- The son of Tatsugoro and Onaka. 
- Takidashi Kisaburo 
- A local leader regarded by Tatsugoro as a personal boss. Having connections with officials both in the town (which has authority over the firefighters) and the shrine (which has authority over the sumo wrestlers), he intervenes in the fight to bring the two sides to peace. 
- Kuryuzan Namiemon 
- An up-and-coming sumo wrestler junior to Yotsuguruma. Modeled on an actual wrestler of the period. He starts a fight in the playhouse over a drunken spectator, sparking a large conflict. 
- Fujimatsu
