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, and was promptely knocked out. 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 implants its hatred into the chakra, causing Naruto to exit Sage Mode and he began to be consumed by it. When Naruto is almost overwhelmed by the fox's hatred, Kushina Uzumaki appears.
