Time Travel saving Rin

Naruto travels through time to the point where Rin gets the Bijuu put in her. He kills the people who did it and corrects the seal to a lesser version of his 8 trigrams.

"You'll thank me later. Make sure to marry Obito and have his kids." Naruto says before disappearing.

Rin tells Minato about the guy that looked really familiar to him only with whiskers on his face.

Fast forward to the birth of Naruto and the 9 tails getting out. Rin and Obito are in the village still so someone else was manipulated to cause it and Obito and Rin, who already have kids of their own take Naruto in.
