Fire Daimyō (Part I-II)

The current daimyō of the Land of Fire is the leader of the country, and husband of Madam Shijimi.

Personality
The Fire Daimyō's character is still to be discovered. When in need of fast, important decisions, he makes his advisors do the whole work: the one, who convinces him most, is the "winner". He seemingly had a liking for Jiraiya, wanting to choose him as the next Hokage, but was also impressed by Kakashi Hatake's reputation. However, the daimyō is shown to be a conformist, as, during the emergency Hokage election, he is easily swayed by Shikaku Nara's recommendations and, finally, persuaded by Danzō's ideologies.

Search For Tsunade Arc
The Fire Daimyō was briefly mentioned to having been at an emergency meeting after the Third Hokage's death to chose a new Hokage; their choice from this meeting was Jiraiya.

Invasion of Pain Arc
Following the destruction of Konoha by Pain, the daimyō assembles a meeting to discuss how to proceed. Although he is reluctant to replace the comatose Hokage, Tsunade, he likes Shikaku Nara's idea of Kakashi Hatake becoming Hokage, especially when learning that Kakashi's teacher was the student of Jiraiya who was the student of the Third Hokage.

However, Danzō points out that the teachings that were passed down to Kakashi were the cause of Konoha's problems and current crisis. The invasion of Konoha, the frequent confrontations with Akatsuki, the desertion of Sasuke Uchiha, and the destruction of the Konoha's infrastructure, all stemmed from the ideology that kindness and unity would lead to peace. Danzō believed the ideology simply made Konoha appear weak and left them exposed to attacks. He then nominates himself and states that he will take Konoha in a new direction, something one of the daimyō's advisers agrees with. The daimyō, persuaded by Danzō's words and reasoning, appoints him as acting Hokage instead.

Five Kage Summit Arc
After Danzō's demise at Sasuke Uchiha's hands, the daimyō were informed of the formation of the Allied Shinobi Forces, and along with the other daimyō of the Five Great Shinobi Countries, they approved of the alliance's existence. The Fire daimyō then had a meeting with the council members and was prepared to elect Kakashi Hatake as the next Hokage, but Tsunade was reported to have awakened.

Shinobi World War Arc
During the war, the Fire daimyō, and along with the other country daimyō, have relocated to a guarded safe house. The Fire daimyō doesn't appear to be too worried about being cramped up in the safe house and instead wonders what they should name the medals that will be presented to the shinobi after the war.

Naruto Shippūden 3: Inheritors of the Will of Fire
He appeared (as a silhouette) when he summoned Tsunade to explain her attempted actions of forming a shinobi alliance against the threat of a Fourth Shinobi World War declared by the missing-nin Hiruko. Apprehensive that Konohagakure might be planning a coup d'etat against the Land of Fire, he charged her of clearing the conflict immediately, lest Konohagakure be threatened with destruction.
