A Shinobi's Dream

is episode 382 of the Naruto: Shippūden anime.

Summary
The five Kage are en route to the battlefield atop Gaara's sand. From the distance, they see the tree form of the Ten-Tails and Katsuyu proceeds to explain the current situation. Meanwhile at the battle ground, Shikamaru is struggling to survive after having his chakra absorbed by the holy tree. Sakura then tries to have Katsuyu heal him but her clones also died from the attack. Naruto cries after the witnessing the deaths of his comrades and Obito attempts to break his will once again. Hashirama tells the Alliance not to give up because the fate Obito wanted for them is worse than death. Orochimaru then arrives at the battlefield alongside Suigetsu and Karin. As Hashirama continue battling Madara, the Uchiha notes that the tree will bloom in approximately fifteen minutes, and that he will switch places with Obito via Hashirama's senjutsu abilities. Hashirama then relays the information to everyone via Ino's technique. A Susanoo-clad Sasuke cuts one of the Ten-Tails' tree form's branches and asks Naruto if he had reached his limit. Naruto enters Tailed Beast Mode and Sage Mode and his thoughts are conveyed to everyone through Ino's technique. Sasuke has Jūgo activate his Sage Transformation on his Susanoo and the two plunge back into battle against Obito. With the shinobi remaining somewhat unmotivated, Hashirama shares with them his memory of the first ever Kage Summit. Hashirama's dream is revealed – to unite the shinobi world. With renewed determination, the troops prepare themselves for battle as the five Kage arrive to the battlefield, all standing as a united front.
