"The Seal Destroyed!!" (封印破壊!!, Fūin hakai!!) is chapter 438 of the original Naruto manga.
Summary
Since Naruto has entered a six-tailed form, the First Hokage's necklace tries to restrain him. Naruto destroys it. Yamato, elsewhere on a mission, senses this and rushes back to Konoha to subdue the demon fox's influence. Ninja around the village sense the demon fox too and try to escape the area. Naruto and the Deva Path begin fighting, but the Deva Path realizes it lacks the raw power to be a match for him. It retreats to a location closer to the base Pain, Nagato, allowing it to use Chibaku Tensei.
