"Give me more power."
During her flight, Karin suddenly started talking as if to herself.
Though the air around her spontaneously formed a barrier blocking sound, there was no one in mid-air who could hear her words.
Except...
"Don't go too far, human!"
The same voice emerged from Karin's mouth once more.
However, Karin herself paid no attention to these words at all. She simply silently increased the overdrawing of her life force.
"Damn it!"
Momoshiki, the Otsutsuki Clan's member who had unfortunately died by Karin's hand in another timeline, was now roaring in frustration.
But he had no choice. He had to use the Chakra he had painstakingly 'intercepted' and converted to replenish the life force Karin was overdrawing.
Because his life was now completely bound to Karin's.
Unlike Naruto, who chose to use Kaguya as a source for extracting power, the relationship between Karin and Momoshiki was closer to that of Boruto in another timeline.
The deficiency from her first awakening had been compensated for by Naruto from another timeline using Yang Release… along with part of Momoshiki's Chakra.
It was precisely because Momoshiki's Chakra combined with the Mythical Zoan power within Karin's body during this process, even altering the Garuda transformation itself, that her hair had remained white. Even after her life force recovered later, her hair could not revert to red.
To put it simply, it was as if her DNA had been influenced by Momoshiki's DNA, causing a physiological mutation.
Of course, this was just an analogy. The actual fusion process might be even more abstract.
Originally, following his plan, Momoshiki had prepared to lie dormant within Karin's body, waiting until he absorbed enough Chakra to complete his reincarnation within her.
Given the Otsutsuki Clan's absolute control over Chakra, this possibility was quite high.
But perhaps due to Garuda's influence, he couldn't easily separate his portion of Chakra from Karin's body.
So much so that whenever Karin chose to enter her Awakened state again, his Chakra would naturally flow to her, actively replenishing her.
This was somewhat different from Kurama's situation back then.
After all, Kurama had been proactive. If he had been ruthless enough to go for mutual destruction, Naruto would probably have long since ended up in a coffin from overtraining.
For Momoshiki, however, it was passive.
It's like you can control your hand to wave freely, but you can't control your organs to secrete specific hormones.
His Chakra was in a similar situation.
Though he could still use it as if commanding his own limbs, when this body was truly in crisis, the Chakra would 'spontaneously' attempt a remedy.
Even Momoshiki himself couldn't control this.
For example, just now, when Karin was blasted away by Kaguya, Momoshiki could only watch helplessly as his own Chakra began very 'foolishly' repairing the body of his enemy.
Using health as mana was, of course, very inefficient. To avoid being directly overdrawn to death by this foolish woman, Momoshiki chose to temporarily yield.
He allowed Karin to directly use a portion of his Otsutsuki Chakra for combat.
This way, at least the Chakra wouldn't have to go through the conversion from Chakra to life force, and more Chakra could be preserved.
So, though unwilling, sensing Karin's unwavering resolve, Momoshiki obediently increased the supply of Chakra.
In an instant, Karin's flying speed increased again, instantly leaving Sasuke far behind.
By the time Karin flew up high, the battle between Naruto and Kaguya was already in full swing.
It was nothing like the relaxed ease when fighting the Five Elders.
Senjutsu, Haki, Genjutsu, Taijutsu, Swordsmanship.
It could be said Naruto was using almost every technique he had learned over the years.
Yet Kaguya on the other side seemed to be copying him. Whatever Naruto used, she could also mimic something similar.
Not only had she mastered Haki, but even the combat skills Naruto had painstakingly acquired over the years were completely learned by her.
Boom!!
"Divine Departure!"
Even Roger's famous technique was blocked.
A white substance, like a Truth-Seeking Ball, formed a long sword, which also slashed out a strike entwined with Conqueror's Haki.
No... it might not even be Conqueror's Haki, but some other, more peculiar spiritual power.
"You can even learn this? You've really 'grown' quite a bit, Kaguya."
Though Divine Departure was blocked, Naruto still has a smile on his face.
"Foolish one. I am now stronger than before. This time, it is you who should die!"
Kaguya's response was full of hostility.
This hostility wasn't solely due to Naruto defeating her before and thwarting her plans.
Even Naruto himself wasn't fully aware.
When he used the Baku Baku no Mi to digest the Otsutsuki Clan's power, the Otsutsuki Clan's 'self-preservation mechanism' was also struggling frantically.
The Kama and the Baku Baku no Mi, two powers from different worlds, competed against each other. This was a great torment for Kaguya.
From Kaguya's perspective:
After being defeated by Naruto, before her body could even heal, she was swallowed whole by him.
Then, the nightmare began.
Kaguya 'watched' as she was gradually 'digested' by Naruto bit by bit.
Her body, energy, and even consciousness were gradually erased in this process.
Unlike Momoshiki, who could maintain self-awareness and occasionally actively appear in the form of illusions, Kaguya suffered far more.
She was forced to fuse with Naruto, her self gradually disappearing as her consciousness faded.
If not for the Otsutsuki Clan's final 'self-preservation mechanism' keeping her barely present, Kaguya might not even have this last remnant of consciousness.
However, precisely because of this experience, after absorbing Imu's pure spiritual energy to reshape herself, she, who 'reborn' from within Naruto, benefited from misfortune and nearly 'shared' everything about Naruto.
Naruto's decades of memories were also shared with her.
Thanks to her own long lifespan and vast life memories, Naruto's few decades of memory fragments didn't cause Kaguya to 'doubt her self'.
On the contrary, she thus mastered various skills and experiences Naruto had acquired.
With this, Kaguya's final shortcoming was filled.
Now, she could almost be considered a copy of Naruto.
Not only that, but due to Imu's influence, she also indirectly mastered some abilities related to 'demons'.
Hum-
A vibrating black sphere appeared in Naruto's hand, beginning to wildly distort the surrounding gravity.
But Kaguya also mimicked him, creating a Black Hole Rasengan of her own.
"Although I wish to kill you..."
"I must admit, Uzumaki Naruto, you truly have talent."
"With power capable of destroying a planet, even if the Otsutsuki main family comes again, it will not be a concern."
For Kaguya, who had once traveled across the cosmos, she was well aware of just how absurdly powerful a celestial body like a 'black hole' could be.
"Ha, so after all that, you're still afraid of those so-called main family's members?"
Naruto let out a scornful laugh.
But this didn't anger Kaguya.
She merely looked at Naruto with a disdainful gaze.
"Narrow-minded mortal."
"Do you think Momoshiki and Kinshiki represent the true power of the Otsutsuki Clan?"
"Your vision, confined to this single planet, is utterly insufficient to comprehend the true terror of the Otsutsuki."
Having said that, she no longer hesitated, forcefully launching the black sphere in her hand.
Seeing this, Naruto could only respond in kind.
Two black holes collided in mid-air, and immediately after, a fissure-like crack appeared in the air.
A tremendous attractive force emanated from within, to the point where even Naruto and Kaguya struggled to control their movements.
In that moment, both sides sensed a lethal threat from that fissure.
If Yomotsu Hirasaka was like 'cutting' a safe passage through the world-
Then the opening torn by the black holes just now seemed to have completely pierced through the world's barrier.
It was something more terrifying than beyond the universe.
Even without Observation Haki, both Naruto and Kaguya could sense that irresistible spatial turbulence.
Going in would mean certain death.
Both sides silently came to that conclusion.
Fortunately, this world itself seemed to possess some self-repair ability. The spatial fissure only lasted a few seconds before sealing shut again-
As if nothing had happened.
But whether it was Naruto or Kaguya, in the subsequent battle, they both very tacitly refrained from using the Black Hole Rasengan again.
