Going back in time!?

Naruto Uzumaki Namikaze Senju goes back in time with Sasuke Uchiha, and their head strategist Shikamaru Nara. Why they went back? Well Madara Uchiha had made himself the jinchūriki of the ten tailed beast, and had used the ten tails power to destroy all of the ninjas and their nations. The only people that have survived are those three Naruto Uzumaki Namikaze Senju the hokage, Sasuke Uchiha the ANBU chief, and Shikamaru Nara the head strategist. All beyond the power of SSS class rated ninjas.

When they go back in time what will they change and what will happen once they change something, will cause a different future from the one they knew or will it be the same and have failed those they protect? The only way to find out is to read it yourself. But the true question is will they save the future and the ones they hold dear or will they fail them and no longer have anyone on the face of the ninja world?
