When Tobi departed, the Kage and Mifune discussed their plans on dealing with Tobi and the tailed beasts and later Mifune suggested that the Fourth Raikage be the Supreme Leader ( 大権, Taiken) of the alliance to which the other Kage agreed. The coalition was formed after Tobi's declaration of war after the five Kage and the head of the Land of Iron, Mifune, unanimously refused to hand over Killer B and Naruto Uzumaki, the jinchūriki of the Eight-Tails and the Nine-Tailed Demon Fox respectively at the Kage Summit. After the summit, the five daimyō agreed to give power to their Hidden Villages, making the Shinobi Allied Forces official. However, before Kakashi was made Hokage, Tsunade woke up from her coma, and resumed her post.

Because of the deceitful actions of the Sixth Hokage Candidate Danzō Shimura, the other Kage asked Kakashi Hatake about Konohagakure's entrance into the alliance as they deemed him the most suitable candidate to assume the office. The purpose of this alliance is to stand up together against the threat of the Akatsuki organisation and the tailed beasts in the Fourth Shinobi World War. The Allied Shinobi Forces ( 忍連合軍, Shinobi Rengōgun) was a coalition between the collective military might of the shinobi nations of the Lands of Lightning, Water, Earth, Wind, and Fire, and the lone samurai nation of the Land of Iron.
