Kakashi vs. Obito

Summary
As the Ten-Tails burns, Sai questions Jūgo about Sasuke's true motives. Elsewhere, the rejuvenated Kage make preparations to join the battle. On the battlefield, Naruto instructs Sasuke to put out the flames once the beast is weakened so that he and Kurama can extract the tailed beasts but Sasuke refuses, as he intends to burn them all down and create a new system. Sai questions Sakura about her views on Sasuke's return, but believes that her smile over the situation is fake. The Ten-Tails then easily separates its burning flesh from its body. Meanwhile, in Kamui's dimension, Kakashi and Obito pierce each other with a Lightning Cutter and a Fūma Shuriken respectively. Deciding to quit using genjutsu, Kakashi and Obito begin their real battle while thinking back to the time they sparred as children. Kakashi reminisces about the young Obito's similarities to Naruto and decides that he must kill the current Obito. He impales Obito's heart with a lightning-infused kunai, but Obito declares that he will not concede the war and teleports to the Ten-Tails' head. Easily dispatching Hashirama's wood clone, Madara notices Obito's return and causes black rods to emerge from Obito's right half. Realising Madara is controlling Obito in order to revive himself, Hashirama tells Naruto and Sasuke to deal with Obito while he and Tobirama produce clones to attack Madara as a contingency plan. As Obito's hair turns white from overexertion, Sasuke attempts to attack him in vain, but Minato's shadow clone teleports to him and cuts him down. Shocked to learn that he was the masked man, Minato questions Obito, but he doesn't answer as the Ten-Tails is suddenly absorbed into his body. Naruto informs Sasuke and Minato that Obito had resisted Madara's control, and the three observe his transformation into the Ten-Tails' jinchūriki.
