The Fourth Hokage

Minato appears within Naruto's psyche, revealing himself to a chakra imprint of the actual Fourth Hokage as he takes Naruto to another part of his mind to discuss things away from the furious Nine Tails. It was there that Minato revealed himself as Naruto's father, making Naruto further conflicted on why his own father made him a jinchuriki. But Minato reveals he only sealed half of the Nine Tails into Naruto, revealing that the Nine-Tails' attack on the Hidden Leaf Village 16 years ago was Tobi's doing, theorizing that Pain may be a pawn of the masked ninja to Naruto's shock. Placing his faith that Naruto will find the answer to Pain's question, Minato restores the Nine Tails seal before fading away. Back to normal, and no means to renew his Sage Mode, Naruto confronts Pain and demands to meet Nagato himself. Pain refuses, resulting in a fight with Naruto stabbing himself with a Chakra Receiver to pinpoint Nagato's location. After using up his last Rasen Shuriken followed by a mass clone attack to force his opponent to exhaust his gravity manipulation, Naruto uses the 5-second window to land a Rasengan on Pain.
