Sasuke is sitting under a tree eating a rice ball, and Kuron rushing towards his location after defeating Naruto as Kuron reached his location he jumped towards Sasuke with his Katana drawn. Sasuke grabbed his blade and clashed with Kuron's Katana, then clashed once more as Kuron's feet hit the ground then Kuron used kakashi's kamui to teleport Sasuke's sword and stabbed him. Kuron pulled his Katana out of Sasuke's stomach then he put his Katana back in it's holder with his back to Sasuke as he dropped to the ground.

As the boulder that killed Obito fell the black hole like portal appeared behind Obito and pushed him out of the way of the boulder with a kick before disappearing before the boulder hit the portal. Now that Obito didn't die, the nine tails attack never happened but Naruto still had the nine tails sealed inside of him when his mother Kushina died.
