After completing his plan to deal a devastating blow to the Iwagakure Shinobi Army, Nawaki handed the fighting on the eastern battlefield of the Land of Earth over to the Allied Forces under Yahiko's command. He himself remained on the western battlefield to oversee the overall situation.
Thanks to the earlier surprise attack, Konoha and the surrendered shinobi forces of the Land of Demons and Land of Birds had occupied nearly the entire western region of the Land of Earth.

Now, hundreds of thousands of shinobi forces had gathered in the western region. Of them, two hundred thousand had originally belonged to the branch ninja villages.
