"The Sharingan Revived" (写輪眼、再び, Sharingan, Futatabi) is episode 473 of the Naruto: Shippūden anime.
Naruto severs Black Zetsu from Kaguya for insulting Obito, and immobilises him. Kakashi laments his powerlessness and thinks back to his failures. Elsewhere, Obito asks Rin to wait a bit longer, as he wishes to aid Kakashi. Obito's chakra rises from his ashes and envelops Kakashi. Reunited, Obito reminds Kakashi to not follow him to the afterlife anytime soon, and tells him to become the Sixth Hokage, in which he gives him a "promotion". Kaguya knocks Sasuke back, and Naruto attacks her with his enhanced Rasenshuriken, resulting in Kaguya undertaking an unstable Tailed Beast transformation. The beast's hands begin attacking, and when they aim for Sakura, she is saved by Kakashi's Susanoo. As he joins the fight, Kaguya creates a gigantic Truth-Seeking Ball and reemerges. While Team 7 confronts her, Kakashi uses his newfound techniques against Kaguya. Naruto and his disguised clone faces her, and when Kakashi warps away Black Zetsu's attack, Sasuke swaps with the clone as Sakura punches her. Kakashi remembers meeting his students, before Naruto and Sasuke make physical contact with Kaguya in order to seal her.
In the manga, Sakura breaks Kaguya's left horn when punching her down while in this episode, it remains intact.
