Having revealed the truth of Itachi and the Uchiha Massacre to Naruto, Kakashi, and Yamato, Tobi chides Kakashi's notion that Sasuke would simply return to the Hidden Leaf as he reminds them that Sasuke is a hate-filled avenger. Tobi tells of how the Sage of Six Paths had two sons and entrusted the younger brother who valued love and friendship with his legacy, causing the power-obsessed older brother to be consumed in enough hate to wage a war that continued through their descendants: The Uchiha and the Senju from which the First Hokage was born into. Tobi explains that Sasuke is the sole heir to the Uchiha's Curse of Hatred and that Naruto has inherited the Senju Clan's Will of Fire, explaining the two are bound to fight each other soon enough before vanishing while cryptically hinting his intent to become "complete". At the Kage Summit, with Suigetsu and Jugo removed from the fight, Sasuke battles Ay while Karin locates Danzo with his sensor ninja Fu Yamanaka and Ao sensing it. Sasuke displays his ability to manifest parts of his Susano'o while manipulating his Amaterasu flames to take out Ay's arm, the Raikage saved from being fully incinerated by Gaara's intervention as he attempted to reason with him. But Gaara is forced to launch a combined assault against Sasuke with Kankuro, Temari and Darui, only for their attacks to be blocked Sasuke's fully manifested Susano'o.
