"Orochimaru's Return" (復活!! 大蛇丸, Fukkatsu!! Orochimaru) is episode 341 of the Naruto: Shippūden anime.
Suigetsu proceeds to show Sasuke the scroll that he found at Orochimaru's hideout earlier. After examining its contents, Sasuke's next motive is to meet with Orochimaru and explained to a confused Suigetsu that he is not one to die so easily as well as declaring that he is going to meet the "ones who know everything". With Jūgo's assistance, Sasuke revives Orochimaru via the Evil Releasing Method. Expressing shock that Sasuke would be the one to resurrect him, Orochimaru asserts that he has no interest in the war. Instead, his sight is still set on Sasuke's body but notes that such a task cannot be completed in his current state. Sasuke then shows Orochimaru the scroll he was given earlier and states he wants to get answers from those who know everything. With that, after absorbing his chakra from the incapacitated Kabuto, Orochimaru agreed to his disciple's request as they prepare to depart. Elsewhere, Naruto and the others watch on as Tobi moves forward with the revival of the Ten-Tails. Kakashi wonders why Tobi would bluff because the Eight and Nine-Tails' chakra are still intact, to which Gyūki notes that Akatsuki may have its chakra from its clone. Kurama further notes that its chakra might be present in the treasuredtools that the Demonic Statue swallowed earlier. With the situation analysed, Kakashi is determined to stop the Ten-Tails' revival from being completed, which Kurama agrees. However, the masked man declares that even if the beast's revival is incomplete, the Infinite Tsukuyomi can still be achieved either way. As the group is rallied to fight, Naruto enters his Nine-Tails Chakra Mode and attacks the statue.
