A lot of people were aware of the powers possessed by the Nine Tails, and the chaos that would erupt as soon as The Nine Tails hovered out of control was pretty predictable.
Madara fails to exercise enough control over The Nine Tails, as he is eventually forced to release it. As a result, it starts wrecking havoc of an unimaginable scale.
Though the Third Hokage tries his levels best to push the creature out bounds of the village, the Nine Tails proves out to be more powerful and a creature, beyond his control.
As a download of the last installment of Naruto Shippuden depicts, lucky for the village, Minato arrives and pledges to take down the seemingly invincible Nine Tails. With the help of the Gamabunta toad, Minato is able to restrain the creature for a time period long enough for his family to carry it outside the village.
But, The Nine Tails was no ordinary creature that could be gotten rid of by sheer transportation. Kushina arrives at the scene to offer Minato assistance by using her chakra to bind the creature.
Minato gets ready for the ultimate sacrifice as he feels only by using both, the Death Reaper seal, and the Eight Trigrams seal can he seal away half of the Nine Tails chakra and contain the rest in Naruto.
The sacrifice is made, and only now is Naruto able to tame the Nine Tails. Naruto knows that without Minato and Kushina, it would have been difficult for him to save his life this time.
The installment ends with Minato and Kushina blurring out their last words closing their eyes forever, and thereby, securing their friend’s life from all the danger brought forth by the Nine Tails.
So yeah, Naruto has been lucky with friends, who have been there no matter what.
