Naruto: Shippuuden

Synopsis

Though freed from Tobi's control, the masked ninja considering it a minor setback, the vengeful Nine Tails continues wreaking havoc as Hiruzen and the ninja work to force the tailed beast out of the village. But Minato returns to the city and employs Gamabunta to restrain the Nine Tails long enough for him to teleport it along with his family to the village outskirts. After Kushina binds the Nine Tails in her chakra chains, intending to absorb the tailed beast back into her body with the process killing her. But Minato points out the flaw as the Nine Tails would eventually reconstitute itself and cause a power vacuum, revealing his intention of sacrificing himself to stop the chaos Tobi intends to create. Minato uses the Reaper Death Seal to take the yin half of the Nine Tails into himself so the weakened Tailed Beast can be sealed within Naruto. When the Nine Tails makes a last ditch attempt to break free, Minato and Kushina sacrifice themselves to take a death blow meant for their son. After imprinting chakra-based manifestations of themselves to aid Naruto in taming the Nine Tails, Minato and Kushina bid their son farewell.
