"A Will of Stone" (石の意志, Ishi no Ishi) is episode 332 of the Naruto: Shippūden anime.
The intense battle between Madara and the five Kage continues as Ōnoki attacks Madara with a gigantic rock golem. However, Madara counters with his Wood Release: Advent of a World of Flowering Trees technique, shattering the golem into pieces. Tsunade remembers the technique being her grandfather's and as the technique released its pollen, she instructs the Kage not to inhale. Gaarasuspends the Kage and Ōnoki levitatesA. Kabuto muses on how people thought no other shinobi is as powerful as Hashirama Senju, just like how people consider the powers of the Sage of the Six Paths a myth. Elsewhere, the Hokage Guard Platoon along with Dodai and Sagan continue to pursue Mū. While the Kage are distracted, Madara unleashes his Susanoo, causing them to fall through the trees. Madara proceeds to set the forest ablaze and not long after, the five Kage are knocked unconscious. Ōnoki, continuously losing his consciousness, remembers of his talk with the First Tsuchikage about the strong will of the Iwa shinobi. Refusing to give up, Ōnoki destroys the forest created by Madara with his Dust Release and as a result, the Kage regained their consciousness. As Madara's body is reforming from the Tsuchikage's attack, to the Kage's horror, the face formed from the DNA of Hashirama Senju appeared on Madara's chest. Meanwhile, Itachi continues his search for Kabuto, as Sasuke detects the former. Sasuke follows him but his brother refused to talk to him. With no choice, Sasuke attempts to catch Itachi with his Susanoo, only for Itachi to counter with his own. The two begin to have a conversation. Meanwhile at the battlefield, Madara decides to take out Tsunade first after realising she was a Senju and also deemed her a weak woman, pathetic compared to the likes of her grandfather. Tsunade stated that she inherited something more than power from her grandfather — the Will of Fire — something that Madara should not take so lightly.
When Itachi talked with Sasuke, Itachi's left sclerae mistakenly appeared normal in one scene instead of black sclerae.
