"It's even stronger than my fusion with the Eight-Tails! How the heck did he pull that off?"
Watching Naruto in his Kurama Mode, Killer Bee was secretly stunned.
Others might not grasp what Kurama Mode signified, but as a fellow Jinchūriki, Killer Bee knew it all too well.
This was the highest level of fusion between a Jinchūriki and their Tailed Beast.
It had taken him decades to achieve fusion with the Eight-Tails, Gyūki. Yet Naruto, after training with him for just half a day, had reached this level of fusion. How could Killer Bee not be shocked?
"By all accounts, Naruto's pretty dense, and the Nine-Tails has a nasty temper. They shouldn't have been able to fuse to this degree. But now they're perfectly in sync. Without some kind of mediator, this would've been impossible. Who helped Naruto and the Nine-Tails fuse so successfully?"
As Killer Bee pondered, his eyes fell on Kazama, who was smiling nearby. Suddenly, it clicked.
"Since Kazama was the first to know about Naruto's successful fusion with the Nine-Tails, it must've been him who made it happen. That kid's seriously impressive. But if he has this kind of ability, why'd he go out of his way to find me and ask me to help Naruto master the Nine-Tails' power? This guy's impossible to figure out!"
The more Killer Bee thought about it, the more his head hurt. In the end, he gave up trying to puzzle it out—he wouldn't get anywhere no matter how hard he tried.
"Awesome! So this is the power of fusing with the Nine-Tails!"
Now in Kurama Mode, Naruto leaped into the air and unleashed the Nine-Tails' chakra in its full form, leaving Yamato and the others in awe and sending the island's animals scrambling in panic.
"Nine-Tails, thanks for helping me!" Naruto said excitedly to the Nine-Tails within him.
"Don't get the wrong idea, kid. If it weren't for Kazama, I wouldn't have let you borrow my power," the Nine-Tails replied.
"What? Kazama?"
Hearing this, Naruto realized he'd been able to tap into the Nine-Tails' power so easily because of Kazama's help. And judging by the Nine-Tails' tone, it seemed to hold a deep respect—or even fear—for Kazama.
This only made Naruto feel even more grateful and impressed by Kazama.
"Kazama, thank you so much!"
Naruto dispelled the Nine-Tails' chakra and rushed over to Kazama, beaming. "The Nine-Tails told me everything. You're the one who got him to help me. I can't thank you enough!"
"What? Kazama can command the Nine-Tails?!"
Hearing Naruto's gratitude, Yamato, Kai, and Killer Bee were all shocked.
Killer Bee, in particular, had always thought he was the only one in the world who could perfectly control a Tailed Beast's power. But seeing Kazama, he realized there was always someone better.
Not only was Kazama more skilled at controlling Tailed Beasts, but he could even make them obey his every word—something Killer Bee could never do.
With Naruto mastering the Nine-Tails' power, Kazama had successfully absorbed the Nine-Tails' chakra, gaining the power of the Ten-Tails, along with the new Nihility Devouring Flame and the Six-Tomoe Rinnegan.
Next, Kazama was ready to start preparing to absorb the power of Ōtsutsuki Kaguya.
Only by absorbing Kaguya's power could Kazama unlock the Nine-Tomoe Rinne-Sharingan.
So, while the others were resting, Kazama quickly called for Obito.
