"The Burden of Being a Kage" (影を背負う, Kage o Seou, Viz: Burden of a Kage) is chapter 588 of the original Naruto manga.
As Kabuto remains incapacitated by Izanami, Sasuke questions whether undoing the Impure World Reincarnation would not mean Itachi would disappear as well. Declaring that he no longer had any attachment to the world of the living, Itachi notes that he was proud to be able to protect Konohagakure once more. Enraged to hear Itachi's motives, Sasuke states that while he could forgive his brother, he could never forgive the village for what they had done. This leads Itachi to tell his little brother that he won't be the one to change him and that he was doing this to aid Naruto Uzumaki — whom he had entrusted that task to. Itachi then proceeds to raise the brille over Kabuto's eyes and uses genjutsu to order Kabuto to teach him the hand seals needed to stop the Impure World Reincarnation. Meanwhile, the five Kage struggle to hold their own against Madara's twenty-five Susanoo-clad wood clones. Amidst all the struggles, Ōnoki rallies them to fight on having been entrusted with a great task at which they could not fail. Madara notes that he needed to break Ōnoki's will as it was the most troublesome of all. Rallying to each other's side, Tsunade transfers chakra to Ōnoki who uses a large-scale Dust Release: Detachment of the Primitive World Technique which succeeds in obliterating the twenty-five clones and part of the real Madara, in one fell swoop. Splitting the cube down the middle, Mei unleashes a Water Release: Water Dragon Bullet Technique which A charges with lightning. This makes contact with Madara effectively slowing down his response time. As Madara prepares to counter, it is revealed that sand was also concealed in the dragon which Gaara uses to bind Madara's movements further in order to create an opening for Ōnoki to use another Dust Release thus giving time to seal him during the regeneration process. After they declared that this was the power of the five Kage, Madara compliments them stating that he would respond with his full power as well. He then unleashes the complete version of his Susanoo stating that it would help them realise just how futile their efforts have been, regardless of being Kage.
