"It was Obito Uchiha" (うちはオビトだ, Uchiha Obito Da) is chapter 654 of the original Naruto manga.
Naruto reaches out his hand to Obito. However, instead of holding his hand, Obito tried to strangle Naruto, saying he has no regrets for anything he has done so far. Naruto punches Obito aside claiming he's not worthy to be a Hokage. Obito begins to see more of his old self in Naruto. Naruto then tells him that Rin wanted to look forward to "Obito Uchiha", not what Obito has become now. Obito remembers his past with Team Minato as he struggles with his inner turmoils, meanwhile Naruto forcefully grabs Obito's hand warning the Uchiha to not underestimate the power of everyone. In the real world, the shinobi's attempts to pull out the tailed beasts were successful. Naruto and Sasuke, losing their armour-cladchakra shroud after winning the struggle, had finally defeated and stopped Obito. Obito looks up to moon and grieves that he could not fill the hole in his heart.
