Fire Daimyō (Part I-II)

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

Personality
The Fire Daimyo'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 Daimyo 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.

Invasion of Pain arc
Following the destruction of Konoha by Pain, the daimyo 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 Leaf village'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 daimyo's advisors agrees with. The daimyo, persuaded by Danzō's words and reasoning, appoints him as acting Hokage instead.

Trivia

 * It is quite possible that the Daimyo was under the influence of Danzō's Mind-controlling Dōjutsu when he nominated him as acting Hokage
