The Promise That Was Kept

is episode 387 of the Naruto: Shippūden anime.

Summary
Though Obito seemingly reaches his hand out, he instead strangles Naruto, claiming he has no regrets for the path he has chosen, much to Naruto's dismay. Frustrated, Naruto breaks free from Obito's grasp and punches him. As Naruto forcibly pulls Obito's hand to his side, the Uchiha is deprived of his powers after the Allied Shinobi Forces succeed in freeing the tailed beasts. Lying defeated, Obito looks up to the moon and grieves that he could not fill the hole in his heart. The tailed beasts then thank Naruto for freeing them. Meanwhile, Sasuke draws his blade and aims for Obito who lies defeated. Just then, Kakashi arrives from the other dimension and pins Obito while pointing his kunai. Kakashi insists Obito is his responsibility and attempts to kill him but is stopped by Minato's timely arrival. The Yellow Flash then convinces his pupil and says that Obito has had a change of heart, prompting Kakashi to withdraw his kunai. Elsewhere, Naruto and the Alliance aim to take down Madara, creating a Big Ball Rasenshuriken — large enough to illuminate the footprints of his comrades.
