Naruto mastering the "Nine-Tails Chakra Mode" was like Sasuke awakening the Mangekyō Sharingan—it was a threshold for a leap in strength. Once he crossed it smoothly, his power would soar severalfold.
Whether in speed or strength, Naruto's "Nine-Tails Chakra Mode" was no weaker than Kumogakure's closely guarded "Lightning Release Chakra Mode."
Moreover, Naruto's "Nine-Tails Chakra Mode" possessed many abilities, including Tailed Beast-level endurance, freely extendable chakra arms, an incredibly keen sense for malice, and the ability to transfer chakra at will.
In terms of overall capability, Naruto's "Nine-Tails Chakra Mode" completely surpassed the "Lightning Release Chakra Mode" that generations of Raikage had relied upon to dominate the Ninja World.
In the entire Ninja World, only Hyuga Kagami's "Tenseigan Chakra Mode," which could condense Truth-Seeking Orbs, could reliably surpass Naruto's "Nine-Tails Chakra Mode" in overall ability.
However, as long as Naruto crossed that threshold and gained the upper hand in his confrontation with the Nine-Tails, then with Naruto's personality, completely reconciling with the Nine-Tails would not be difficult at all.
In other words, after mastering the "Nine-Tails Chakra Mode," it would only be a matter of time before Naruto mastered the even stronger "Kurama Mode."
In "Kurama Mode," Naruto could draw upon all of the Nine-Tails' chakra, easily unleash Tailed Beast Balls, and even perform all kinds of ninjutsu, including Shadow Clones, while fully transformed into a Tailed Beast.
Furthermore, the Nine-Tails within him would continuously refine chakra and even absorb natural energy from the outside world, providing Naruto with an endless supply.
