Nine-Tails vs. Naruto!! (九尾VSナルト!!, Kyūbi Bāsasu Naruto!!) is chapter 497 of the Naruto manga.
The Nine-Tails attacks Naruto with its Tailed Beast Ball, which B blocked using the last bit of the Eight-Tails' power he could manifest within Naruto. Naruto uses this as a distraction to enter Sage Mode and attacks the beast. After a combination of shadow clones and a Rasenshuriken attack on the fox, the Nine-Tails is left vulnerable and Naruto begins to pull out its chakra. The Nine-Tails' hatred begins to seep into the chakra, causing Naruto to become consumed by it. When Naruto is almost overwhelmed by the fox's hatred, Kushina Uzumaki appears.
