Bloodline reversion.
As mentioned before, the Uzumaki clan’s ancestor was Ashura , the younger son of the Sage of Six Paths, Ōtsutsuki Hagoromo.
And the Sage of Six Paths was the elder son of Ōtsutsuki Kaguya.
As for Kaguya, there was no need for further explanation.
She was a member of the Ōtsutsuki Clan who had arrived in the ninja world carrying a Ten-Tails to cultivate.
However, after the Chakra Fruit had matured she consumed it herself.
At this moment, after Naruto unexpectedly revealed so many earth-shattering secrets, the Sage of Six Paths made a bold decision.
He finally granted Naruto the Six Paths power he had long desired.
Not only that because Naruto had somewhat resentfully complained that all of the Sage’s descendants should have inherited the Sage’s Eyes instead of only the Uchiha.
The Sage simply awakened Naruto’s ancestral bloodline.
Since Asura had inherited only the Sage’s Body and not the Sage’s Eyes, his descendants naturally could not awaken ocular powers.
But now Naruto suddenly began to change.
His blond hair rapidly turned white.
Then, from within that snow-white hair, a pair of sharp, wood-like horns slowly emerged.
The bloodline the Sage bestowed upon him was none other than the Ōtsutsuki bloodline he himself had inherited from his mother, Kaguya.
This ancestral awakening brought Naruto’s lineage astonishingly close to that of a true Ōtsutsuki.
Naruto suddenly felt an intense heat burning in his eyes.
He hadn’t noticed it himself.
His originally azure eyes were gradually dyed crimson.
A single tomoe appeared.
Then two.
Then three.
But it wasn’t over.
Buzz.
An invisible sound seemed to echo through the space.
Naruto’s three-tomoe Sharingan spun rapidly.
Finally, the tomoe merged into two black intersecting patterns, forming an X-shaped design.
The Mangekyō Sharingan.
Yet even that wasn’t the end.
His eyes suddenly turned blue again.
Not their original blue.
The Mangekyō pattern expanded outward as black concentric rings spread across his irises.
Nine tomoe appeared upon those rings.
The Rinnegan.
No…
A Tomoe Rinnegan.
Finally…
A white robe identical to the Sage of Six Paths’ own appeared over Naruto’s body.
Black magatama patterns decorated the garment.
At the same time a single black sphere slowly floated into existence behind him.
The symbol of Six Paths power.
It hadn’t been created through Naruto’s own efforts.
Rather, it naturally formed after receiving the Sage’s gift.
Because his chakra reserves were still insufficient, only a single Truth-Seeking Ball manifested.
Even so.
it was still a Truth-Seeking Ball.
Used properly even one possessed world-shattering destructive power.
Kurama had long since been stunned speechless.
He simply stared blankly, completely at a loss.
After finishing everything, the Sage of Six Paths visibly aged.
Even for him bestowing so much power at once had clearly taken a heavy toll.
Naruto finally regained his senses.
Still dazed, he reached up to touch the horns on his head.
Without a mirror, he couldn’t see what his eyes looked like.
But he could feel it.
He knew he had gained ocular powers.
His vision had become extraordinary.
His perception had increased dramatically.
He could even see the flow of chakra itself.
Naruto stood there in complete shock.
The overwhelming surprise left him unsure how to react.
“Um…”
He hesitated before asking with a helpless smile,
“…Weren’t you worried I might have been lying to you?”
The Sage let out a long breath.
Even speaking seemed difficult after everything he had done.
Hearing Naruto’s question, he smiled bitterly and shook his head.
“Do you think I don’t know where we are?”
“And have you forgotten that I once saw your true soul?”
“After you finished speaking earlier I looked into your memories.”
“I’m sorry I didn’t ask your permission but now I know where you came from and I’ve confirmed that everything you’ve said is true.”
“It’s difficult to believe so this world is actually a story created by someone else.”
Naruto froze.
His expression changed instantly.
This was Naruto’s mental world.
In other words it existed entirely within his own consciousness.
Yet somehow, the Sage had managed to peer directly into his memories.
Furthermore, three years ago, when they first met, the Sage had already seen Naruto’s original soul.
At that time, Naruto had still appeared exactly as he had before transmigrating. This story is hosted at g.com.
Through those memories the Sage had also learned the truth behind this world’s existence.
So this really was a fictional world.
Fortunately the revelation hadn’t driven the Sage insane.
Most people probably wouldn’t have been able to accept such a truth.
That also explained why the Sage had suddenly bestowed such tremendous gifts upon Naruto.
Because he now knew everything Naruto had said was true.
He had seen the dangers awaiting the future.
That was why, in one stroke he not only granted Naruto Six Paths power.
He also awakened Naruto’s bloodline, allowing it to surpass Asura and reach the Sage’s own level.
As a result Naruto awakened the Rinnegan.
Since the transformation had begun from the Sharingan during his bloodline reversion it ultimately evolved into the Tomoe Rinnegan.
Unfortunately the Eternal Mangekyō Sharingan required an entirely different method of awakening.
So Naruto hadn’t obtained it.
However.
Since he already possessed Asura’s Sage Body, along with the complete bloodline of Ōtsutsuki Hagoromo himself.
He likely wouldn’t suffer from the blindness that plagued ordinary Mangekyō users.
“…Did you really have to awaken every ocular ability all at once?”
Naruto still hadn’t quite recovered from the shock.
Even the Uchiha clan found these powers nearly impossible to obtain.
Yet he’d reached the pinnacle in one leap.
The Sage shrugged.
“It couldn’t be helped that I was born with the Rinnegan since I restored your bloodline to match mine…”
“It was only natural that you’d also possess the Rinnegan from birth as for the Sharingan it’s merely a weaker form of the Rinnegan.”
“Once someone awakens the Eternal Mangekyō Sharingan and then acquires the bloodline of Asura’s descendants combining Indra’s and Asura’s powers the Rinnegan naturally awakens.”
That explained why Naruto possessed the Sharingan first…
Before it eventually evolved into the Rinnegan.
Suddenly Naruto grinned foolishly.
“So that means I have the Rinnegan now?”
“If I use Outer Path: Samsara of Heavenly Life wouldn’t I be able to revive my parents?”
He had suddenly remembered the Rinnegan’s forbidden technique.
The Outer Path: Samsara of Heavenly Life.
The jutsu capable of resurrecting the dead.
Of course…
It supposedly required the user’s own life as payment.
“…Though I suppose there are other ways.”
“For example I could transplant my eyes into someone else and let them pay the price instead.”
The Sage stared at Naruto in astonishment.
At that moment he felt the faintest trace of regret.
Because this child seemed to have a rather…
questionable personality.
Did I just empower a problem child?
