Chapter 645 has Naruto and Minato blend Sage Mode with Tailed Beast Mode to press their assault on Obito, the Ten-Tails' jinchuriki. Their combined senjutsu attacks force Obito to escalate into his own beast transformation.
Following his talk with his father, Naruto wraps himself in the Tailed Beast Mode shroud and readies a renewed charge at Obito. Tobirama reminds him that only senjutsu can wound the Ten-Tails' host, a warning that briefly throws Naruto into a panic after he had already let it slip his mind.
Within his mind, Yang-Kurama tells him their bond now lets him sustain Sage Mode while drawing on the fox's power, much as he did during his meeting with Nagato, while Yin-Kurama offers Minato a complete transformation to back his son. Heeding the beasts, both fighters enter full Tailed Beast Mode, with Naruto layering it over his Sage Mode.
Minato, aided by Naruto, shapes a large senjutsu-charged Rasengan and, using Tobirama's Flying Thunder God Technique, drives it into Obito. Obito repels the blow with chakra arms and a fluid barrier, so the pair pool their strength into a senjutsu-infused Tailed Beast Ball meant to break through his defenses. Obito answers by beginning his own tailed beast transformation to keep advancing the Eye of the Moon Plan.

Sasuke and the surviving shinobi observe the battle, and Sasuke reflects on just how far Naruto has come. Obito's transformation stuns Madara, who is still locked in combat with Hashirama.
