"A Shinobi's Dream…!!" (忍の夢…!!, Shinobi no Yume…!!) is chapter 648 of the original Naruto manga.
With renewed determination and a chakra boost from Yin-Kurama, Naruto heads back into battle alongside Sasuke — who, not to be outdone, has Jūgo use the Sage Transformation on his Susanoo to imbue it with natural energy, creating the Cursed Seal of Heaven markings on Sasuke's Susanoo. Ready for action, the two young men plunge back into battle against Obito, who took note of how time and time again Naruto would pick himself up from the rut of despair. With this, Orochimaru reflects on how Sasuke seemingly had the potential to surpass even Madara Uchiha himself, while Tobirama notes that Naruto was in a lot of ways like his brother Hashirama: faults and all. With the shinobi still somewhat doubting themselves and contemplating waiting for directives from the current Kage, Hashirama shares with them all his memories of the first summit of the five Kage. How the meeting unfolded is revealed to all; what rings home for them all, is Hashirama's wish for all shinobi to be united. With this, Hashirama rallies the troops to amass their worries, their resolve, their sorrows and strength in order to fight. Ultimately, Hashirama's wish for the future is answered by the appearance of the five current Kage to the battlefield, all standing as a united front.
