The top firefighter of Edo, known as the "Fire-Eating Bird," Matsunaga Gengo retired from firefighting due to a certain incident and lived in poverty as a ronin with his wife, Miyuki. Suddenly, an offer for an official position arrives from the Dewa Shinjo Domain. They plead, "As the chief firefighter, please save Edo once again." To protect lives from the numerous "suspicious fires" plaguing Edo, Gengo resolves to become a firefighter again. He takes on the daunting task of reviving a nearly-defunct fire brigade, mockingly called the "Ragged Fire Hawk Group," and confronts the raging flames to protect Edo and its people!!
