Naruto heard the Fourth Hokage’s announcement that he was his son. He was beyond excited and followed his father to the part of his subconscious where the Nine-Tail would not threaten to kill them both. There the Fourth tells him that he has designed Naruto’s seal so that his imprint will show up even if the seal is on the verge of being broken. Naruto asks why Fourth sealed the Nine-Tail inside his son. The Fourth replied that he only trusted his son to subdue the Nine-tail in order to defeat the masked man responsible for the attack on the Leaf sixteen years ago. They discussed Paine’s view of the world, and Fourth suggested that Paine was a product of the period of war in which he had grown up. This was probably taken advantage of by the masked man. Fourth urged Naruto to find his own solution for peace and for Paine. After restoring the seal, the Fourth disappeared.
