A New Seal!! (新たなる封印!!, Aratanaru Fūin!!) is chapter 499 of the original Naruto manga.
Kushina's words cause Naruto to feel at peace, which makes the Nine-Tails' hatred recede. Naruto makes several shadow clones, and uses several variants of the Rasengan to push the fox back, allowing him to pull out all of its chakra. After obtaining the Nine-Tails' chakra, Naruto's seal takes a new shape, the chakra takes the form of the Sage of Six Paths. Naruto uses the key to close the seal, re-caging the fox. Kushina reveals that she is the previous jinchūriki of the Nine-Tails.
