"What do you... want to do?"
Naruto opened his mouth wide under Black Zetsu's incredulous gaze.
Yet no one present answered Black Zetsu's question.
-Even though they all understood Naruto's intention.
Karin and Jiraiya looked at Naruto with concern. After all, last time he just ate a Zero-Tails and ended up in that state.
This time, what Naruto was about to consume was the legendary [Progenitor of Chakra]!
Sasuke, who had already exited his combat form, however, didn't seem the slightest bit worried.
The reason was simple: he didn't 'see' any 'calamity' on Naruto at this moment.
This meant Naruto's upcoming action wouldn't produce such terrible consequences.
Crackle crackle crackle...
Countless tiny Chakra Chains quickly wrapped around Kaguya, who had already begun to transform into a grayish-white mass of flesh.
The moment those chains touched Kaguya, she instinctively tried to absorb the Chakra from them.
But the outer layer of this Chakra was coated with a layer of Haki sufficient to block contact. This formless, immaterial force significantly slowed down Kaguya's absorption speed.
By the time she barely managed to deplete over a dozen chains, even more newly formed chains wrapped around her.
Amidst this back-and-forth struggle, the already swollen flesh mass, nearly ten meters in diameter, was pulled towards Naruto's mouth.
At this moment, Naruto's body, enhanced by various buffs, had 'grown' to over four meters tall, yet he still appeared much smaller than the mass.
But that didn't matter.
His mouth now broke through the limits of what a 'human' creature could achieve.
As the flesh mass approached Naruto's mouth, it was immediately compressed and drawn in, unable to break free even if it wanted to.
"Mon... ster..."
Black Zetsu's eyes were completely hopeless. He watched as his mother, while in her regenerating state, was devoured alive by this man before him like food.
It seemed even his spirit had developed some issues. This small lump of black mud, now with only half an eye and a mouth left, just kept muttering a few words.
"Mother... Mother..."
Unfortunately, his mother could no longer respond to him now.
Perhaps… Kaguya never truly considered Black Zetsu, this accidental product, as her child in the first place.
In Kaguya's heart, her own true sons, Hagoromo and Hamura, could betray her. So who else in the world was worthy of her trust?
After Naruto completely swallowed Kaguya, his body began to swell left and right, just like Kaguya's form earlier.
It looked like it was about to turn into a mutated flesh mass similar to Kaguya's.
Karin didn't know how to help Naruto at this moment. Her eyes were filled with worry.
Not just her… including Sasuke and Jiraiya, no one present could help Naruto now.
He could only rely on himself.
In Naruto's perception, Kaguya, swallowed by the Baku Baku no Mi, was still struggling.
She tried to regain her human form, but the unreasonable power of the Baku Baku Factory kept decomposing Kaguya's body.
Or rather, it wasn't the Baku Baku no Mi that was powerful, but Naruto, who had eaten it.
The Baku Baku no Mi could indeed grant the user the power to digest anything. But if the user themself couldn't control that power, the final result would merely be a power rampage.
Just like its previous host, Wapol. Even if he got lucky with a sneak attack and swallowed the World's Strongest Man, Whitebeard, would he have the ability to master the world-shattering Gura Gura no Mi?
Hadn't they seen Whitebeard himself, due to the side effects of the Gura Gura no Mi, end up full of internal injuries in his old age?
It was the same for Kaguya.
If someone else had eaten the fruit, the outcome awaiting them would only be one: being completely replaced by Kaguya from within, becoming Kaguya's new body, just like Madara.
But unfortunately, the one currently controlling this devouring power was Naruto.
The outlaw who left the World Government helpless!
The Great Hero who could shake the world's structure single-handedly!
The number one physical powerhouse in the current Ninja World!
Even if another Otsutsuki Clan's member were resurrected, they couldn't surpass Naruto in physical comparison.
Coupled with the hidden power of being Asura's reincarnation, sharing the same origin as Kaguya, Naruto's process of 'digesting' Kaguya could proceed so smoothly.
He could feel Kaguya's resistance and struggle growing weaker and weaker.
In its place, a Chakra of complexity far beyond his imagination was being extracted from within her.
It was the perfect Chakra belonging to the Otsutsuki Clan, possessing all elemental properties… or rather, [Primordial Chakra].
To outsiders, Naruto's body only briefly swelled for a while before he quickly suppressed it again himself.
Then, the Chakra of the Nine Tailed Beasts and Kaguya's own abilities were rapidly extracted and mastered by Naruto.
Under everyone's expression as if they'd seen a ghost, Naruto's skin also slowly turned pale. The cross-shaped pupils of his Sage Mode rapidly transformed towards other directions.
One turned into an eye with a yellow background and black frame, extending towards the center.
The other turned into the Byakugan familiar to everyone.
On Naruto's forehead, as expected, a third eye also opened… the blood-red Rinnegan originally belonging to Otsutsuki Kaguya, capable of casting the Infinite Tsukuyomi.
The golden robe created by his Nine Tails Sage Mode was also replaced by a white robe with tomoe patterns, belonging to the Otsutsuki power.
Naruto's appearance now was even more Otsutsuki-like than Kaguya had been moments before.
"Naruto-san? You..."
What Karin originally wanted to ask was 'Are you still you?', but she swallowed the words back.
She felt it would be strange to say that.
Sasuke wasn't so particular.
He directly entered his combat state and, without any reservation, asked Naruto.
"Naruto, prove your will hasn't been affected."
As he spoke, blue calamity flames and lightning mixed together, wrapping around his claws.
If Naruto's next words sounded the slightest bit strange, he would attack without hesitation.
Seeing this, Karin and Jiraiya also realized and immediately assumed combat stances.
They didn't want to fight Naruto either, but honestly, if Naruto's self-will was affected, they might not last an instant without entering combat mode.
Clearly, Naruto had become even stronger now.
Silently.
The moment Naruto completely transformed into an 'Otsutsuki Clan's member', he vanished from the spot.
This time, even Sasuke's Observation Haki couldn't detect him.
"Relax, don't be so tense."
Everyone's gaze then saw that Naruto was now standing behind them. The 'Otsutsuki' characteristics on his body were also being quickly suppressed.
The eye on his forehead gradually closed, and his pupils also returned to their original sky blue.
Of course, the robe also dissipated as this power vanished.
His entire upper body was exposed naked. The upper body so perfect it seemed sculpted by the god of muscles almost made Karin, this young maiden, bleed from the nose.
Without a doubt, Naruto's power had risen another significant level now.
-But exactly how much it had increased, neither Sasuke nor Karin could tell. Perhaps even Naruto himself didn't know.
But at least one thing could be confirmed: Naruto was still himself. With that speed earlier, if he had lost control and attacked them, they would probably be dead already.
"Hmm... Step back a bit."
Suddenly, Naruto covered his mouth with his hand, as if feeling seasick and wanting to vomit.
Everyone spread out in confusion.
"Urgh..."
In the next moment, accompanied by a very grating sound of vomiting, the Chakra of the Nine Tailed Beasts, including Kurama, were vomited out all at once from Naruto's mouth.
Their forms seemed to have been 'digested' considerably during the process of being first consumed by the Ten-Tails and then by Naruto, making the Tailed Beasts now appear somewhat 'small'.
Of course, this was compared to their original sizes.
After vomiting out these Tailed Beasts, Naruto looked at the center of his palm.
A strange pattern remained there.
The lower part of this pattern was a solid circle. In the middle were two wing-like things. At the very top was another circle within a circle, like the symbol of the Rinnegan.
After obtaining relevant intelligence from Sasuke, Naruto already knew this pattern was the mark belonging to Kaguya that would be found in the future Otsutsuki ruins.
If using professional terminology, this should be considered [Kaguya's Kama].
