You Better…

Summary
Kakashi asks the crumbling Obito why he would sacrifice himself when he was still necessary in battle, but he tells Kakashi to focus on the enemy, before musing that Kakashi needed to survive in order to support the next generation of shinobi, and notes that Naruto, Sakura and Sasuke are a crucial part for the future. Kaguya decides to return to her first dimension while she replenishes her chakra. Naruto tries to use his abilities to save Obito, as Black Zetsu mocks not only about Naruto's futile efforts, but Obito's wasted life; and though Obito agrees to this, Zetsu's words do nothing but infuriate Naruto. Wasting no time when he realised that his dōjutsu's ability was useable once more, Sasuke launches an attack on Kaguya, forcing her to shift dimensions once more to narrowly escape the attack. Noting that this time he would be the distraction, Sasuke engages Kaguya giving her no time to relent as he dons his Complete Body — Susanoo and flies towards her. Obito uses this time to impart his final words to Kakashi and Naruto, thanking them for allowing him to remember who he used to be. After telling Naruto to become Hokage, Obito finally disintegrates into a pile of ash, leading Black Zetsu to comment that Obito was a cockroach for having last so long rather than a regular insect. Enraged at this point, Naruto declares that because he wanted to become Hokage at one point, Obito was an awesome person in his eyes, and proceeded to fly up to Kaguya at an extreme speed, severing her left arm with his own chakra arm. Meanwhile, in the afterlife, Obito finds Rin, who revealed she had been watching Obito all these years, and the two reconcile.
