What If The Seventh Hokage Appeared In The Fourth Great Ninja War?

Three weeks after Kurama died in Baryon Mode, the Seventh Hokage falls asleep over a fence dispute in his office and wakes up falling out of a black tear in the sky, straight into the Fourth Great Ninja War. The Ten-Tails is about to erase the Allied headquarters with Shikaku and Inoichi inside it. He has thirty seconds, no Kurama, no Six Paths power, and one Rasenshuriken. Then his seventeen-year-old self looks down at him in a crater and asks why he's so old. This is Naruto's own account of the day he fought beside himself: two Gama-chan wallets, one wooden arm that Madara recognizes as Hashirama's, a fist bump that lets him see Kurama alive again, and the one death he came back to stop. Neji Hyuga. But saving Neji might erase the moment Hinata first took the kid's hand, and with it his own children. Kakashi refuses to learn who the Sixth Hokage is. Minato meets a son older than he ever got to be. And the only advantage the Seventh brought from the future, knowing how this war ends, is about to fall into the wrong hands.
