When does naruto gain power of the six path?

Naruto gains the power of the Sage of Six Paths during the Fourth Great Ninja War. Specifically, he receives this power from Hagoromo Otsutsuki, the Sage of Six Paths, after he and Sasuke Uchiha awaken their abilities to combat the threat of Kaguya Otsutsuki. This transformation enhances Naruto's abilities significantly, granting him new techniques and the ability to use Truth-Seeking Balls.
