Unison Sign

is episode 277 of the Naruto: Shippūden anime.

Summary
While moving to the battlefield through the night with Naruto's Nine-Tails Chakra Mode lighting the way, B and the Eight-Tails discuss the fact that while the young man could use that form, the Nine-Tails continued to consume his chakra because the two were not on friendly terms. Not wanting to dampen Naruto's determination, the Eight-Tails resigns to have B keep a close eye on the young man. At the same time, the Nine-Tails speaks with Naruto about always being so careless with its chakra, but Naruto simply retorts that the beast had regain shape since it had been consuming his own chakra and that though he guessed that it was lonely and wanted some company, they would have to talk later. Disregarding this, Kurama asks him whether he truly naive enough to believe that he alone could stop a war of this magnitude, with Madara at its helm. The beast then told the young man that he was welcome to use its power, but Naruto states that he wouldn't fall for that one again and begins to leave. Kurama takes this opportunity to tell Naruto about the hatred that would spread because of this war and questions whether or not he was ready to bear such hatred. The beast then reminds him of Sasuke and the hatred the young Uchiha bore and how Naruto had never been able to help him since they were children and had refused to make the Seal of Reconciliation during their Traditional Shinobi Sparring match. This causes Naruto to re-enter the beast's cage and send of of the torii to pin Kurama down. Climbing on the beast's face to look it directly in the eye, Naruto states that once someone started to question their own convictions, it was all over and declared that he would save Sasuke somehow and put an end to the war. He then goes on to state as he left that, if possible, he would like to eventually do something about the beast's hatred as well which greatly angers Kurama who tells him that it was hatred embodied. Lost in thought, B tells Naruto to lighten up as they continue on their path with renewed vigour.
