…of the Sharingan!!

Summary
As Obito prepares to leave with Rin, he asks for her to wait just a little bit longer, when she responds as to why, he says he wants to help Kakashi save the world, in his own, indirect way. Promising Rin to come back, Obito teleport back into the core dimension as a mass of chakra, which quickly latches itself onto Kakashi. Inside his mind, Obito explains that he came back to give Kakashi a "present" to make up having the Sharingan he gave to him being stolen by Madara and also expressing him becoming the next Hokage, before Naruto. Kakashi opens his eyes, revealing that he now has Obito's Mangekyō Sharingan in both eyes. Meanwhile, Black Zetsu is pinned down by two rods when Sasuke is knocked back by Kaguya's chakra arms. Naruto quickly uses a new Rasenshuriken technique against Kaguya, resulting in a massive misshaped mass of the combined tailed beasts chakra pouring out of her body. Soon, the mass begins pirouetting numerous arms, one of them quickly absorbs a Naruto clone. Seeing one of the arms go after Sakura, Naruto tells Sasuke to use his eye power to save her, but instead sees Sakura being carried by a Susanoo. Being surprised that Sasuke wasn't the one inside, it is revealed that it was Kakashi that was inside the Susanoo, declaring in his mind that he and Obito will protect their comrades and the world.
