Although his comrades are defeated, Jin puts his final plan in motion by using Gaara to revive Seimei. To do this, he traps Gaara in a metal sphere that starts draining his chakra. Gaara partially transforms into the One-Tailed Shukaku--which is what Jin wanted all along. Jin then performs a ritual and sacrifices his own body to Seimei's corpse, which allows Seimei to be reincarnated. Seimei then takes up the weapons of the Shitenshonin, therefore becoming the "ultimate weapon" of Takumi Village. Naruto does battle with him until Gaara bursts out of the metal sphere, partially transformed into the One-Tailed Shukaku.
