Although Kaguya's words were blunt and her demeanor somewhat erratic, she was not lying.
The techniques of the Ōtsutsuki Clan are fundamentally tied to Bloodline Limits. A Bloodline Limit that surpasses ordinary Bloodline Limits and Bloodline Expansions is created through the fusion of all seven chakra natures: Fire, Wind, Earth, Water, Lightning, Yin Release, and Yang Release.
At present, only Ōtsutsuki Kaguya and the Sage of Six Paths along with his brother, Hamura Ōtsutsuki, possessed such power. No other shinobi had ever achieved it.
Even someone as powerful as Uchiha Madara, despite awakening the Rinne Sharingan and casting the Infinite Tsukuyomi before using the God: Nativity of a World of Trees technique, still only wielded ordinary Bloodline Limits rather than the higher form.
Without that level of Bloodline Limit, learning Kaguya's techniques was impossible.
Yomotsu Hirasaka, Infinite Tsukuyomi, God: Nativity of a World of Trees, Rabbit Hair Needle, Eighty Gods Vacuum Attack, and Amenominaka were all techniques that belonged to that supreme Bloodline Limit.
Were they powerful?
Without question.
Had Kaguya not spent countless years sealed away until her mind dulled and her combat instincts deteriorated, Uzumaki Naruto and Uchiha Sasuke would never have defeated her.
After all, the Sage of Six Paths and Hamura had battled Kaguya for months before finally managing to seal her away.
Could Naruto and Sasuke at that time truly have surpassed the combined strength of those two legendary brothers?
Obviously not.
The current Kaguya was unquestionably weaker than the one who had once ruled the world.
Yet these were precisely the techniques Hayashi wanted to learn.
He might not possess that supreme Bloodline Limit now, but he had the System.
Its attribute fusion ability was not merely decorative. Since he already possessed all seven chakra natures, once they were completely fused, he would naturally awaken the required Bloodline Limit.
The principle was no different from how the Third Tsuchikage combined three chakra natures to create Dust Release.
Naturally, none of this could be revealed to Kaguya.
Hayashi still intended to learn the Eighty Gods Vacuum Attack from her.
Just imagining it made him grin.
That technique had shattered Sasuke's Perfect Susanoo in an instant and obliterated multiple Six Paths Shadow Clones created by Naruto.
One day, when Madara returned and activated his Perfect Susanoo, Hayashi could simply walk up and greet him with a barrage of Eighty Gods Vacuum Attack punches.
Madara would probably question his entire existence afterward.
The thought alone was deeply satisfying.
Kaguya herself remained hesitant.
To be honest, she had not spoken with another living being in thousands of years. Now that someone was finally communicating with her, she could not bear to lose even the smallest chance of escape.
She had no desire to remain sealed for another thousand years.
Even if Hayashi was deceiving her... so what?
Could her situation become any worse?
But if he truly meant what he said...
She was unwilling to abandon even a one in ten thousand chance.
People were often like that.
A drowning person would desperately cling to even a single blade of grass if it offered the slightest hope of survival.
As for the price of teaching a few techniques, Kaguya did not consider it significant.
Her techniques were incredibly powerful, but true mastery depended entirely on the user's own strength.
She did not believe Hayashi could actually learn them.
Eventually, after failing again and again, he would surely return seeking other rewards. With enough exchanges, there would eventually come a day when an agreement could be reached.
What Kaguya possessed more than anything else was time.
Having secured Kaguya's promise, Hayashi left in an excellent mood as his consciousness returned to the artificial sun.
He had expected a long and exhausting negotiation.
Instead, everything had gone surprisingly smoothly.
Thinking about it, though, it made sense.
For nearly two months, he had visited her every single day. Whether through strange conversations or simple appearances, they had gradually built a strange sort of familiarity.
Hayashi never mentioned this arrangement to the Sage of Six Paths.
There was no need.
The Sage undoubtedly already knew.
Both of them understood one thing.
Hayashi would never release Kaguya.
That was the Sage's absolute bottom line.
As for whether Hayashi was deceiving or manipulating her, the Sage simply did not care.
Twilight settled over the moon.
Golden clouds stretched across the horizon, resembling magnificent towers layered one upon another.
Feeling unusually relaxed, Hayashi casually raised a hand and gently rotated his wrist.
A swirling vortex of chakra appeared above his palm.
At that moment, someone slowly approached from the distance.
It was Ōtsutsuki Kawakui.
Every evening, she came to this pavilion to quietly watch the sunset.
Despite seeing each other regularly, they had never truly spoken.
Hayashi had little to say to her.
After all, Sōgi, the man he had killed, was Kawakui's father.
Originally, Hayashi had expected her to seek revenge.
Instead, nothing had happened.
The one who constantly stirred up trouble was Genjin.
After all, his Tenseigan's power was gradually being absorbed by Himeji, so resentment was only natural.
Still, Genjin never dared act on his anger.
He only complained.
From everything he had observed, Hayashi had already reached a conclusion.
Genjin and Kawakui were most likely Toneri's parents.
By Toneri's era, the older generation of the moon's Ōtsutsuki Clan would have gradually died out, leaving Toneri as the sole survivor.
Kawakui stepped gracefully through the air.
Each time she took a step, a cloud condensed beneath her feet into a solid staircase.
Once she moved forward, the cloud dissolved into mist.
Hayashi watched with genuine curiosity.
This seemed to be Kawakui's unique ability.
He had never seen another member of the Ōtsutsuki Clan perform such a feat.
It was clear her natural talent exceeded that of the others.
No wonder Toneri had inherited such exceptional potential.
This time, Kawakui broke the silence.
"When that Hyuga girl awakens the Tenseigan, can you take me to the shinobi world?"
Hayashi raised an eyebrow.
"You should already know," Kawakui continued calmly. "The passage connecting the moon and the shinobi world is sealed. Only someone with the Tenseigan can release it."
"You don't want to stay on the moon anymore?"
She quietly looked toward the endless horizon.
"I've spent every day looking at the same scenery. The moon is nothing more than a slightly larger prison. It's no different from where Kaguya is confined."
The moon's Ōtsutsuki Clan had been entrusted by Hamura with watching over Kaguya.
Naturally, Kawakui knew far more about Kaguya than most people.
After studying her expression for a moment, Hayashi nodded.
"I can take you to the shinobi world."
He paused.
"But a major conflict is about to unfold."
"A war?"
Kawakui sounded almost indifferent.
"How dull."
She looked back at him.
"Do you need me to participate?"
Hayashi shook his head.
"No."
Without the Tenseigan, her strength would not significantly affect the coming war.
Whether she joined or not made little difference.
"But during that time, you must remain in Konoha. You are not allowed to wander around the shinobi world."
"Konoha?"
"Yes. It's a wonderful village."
He smiled faintly.
"It's also where Himeji and I are from."
"Himeji... an Ōtsutsuki descendant who possesses the Byakugan?"
"In the shinobi world, descendants with the Byakugan are generally known as the Hyuga Clan."
Truthfully, Hayashi still did not fully trust Kawakui.
Fortunately, she was not especially powerful without the Tenseigan.
Her only unusual trait was that Black Zetsu could not detect her.
That was precisely why Hayashi intended to keep her inside Konoha.
After a brief silence, Hayashi suddenly asked,
"You don't seem to like Genjin very much."
Otherwise, why leave him behind and go alone?
Wasn't this practically running away from a marriage?
He glanced at her iconic white Ōtsutsuki hair before grinning.
"If you're going to leave, then leave completely. What's so special about Genjin?"
"When we reach Konoha, I'll introduce you to the current young head of the Hyuga Clan, Hiashi."
"I'm sure the two of you will get along."
"Hiashi?"
"Just like his younger brother, Hizashi, he's young, capable, and dependable."
Hayashi nodded to himself with great satisfaction.
He looked exactly like a successful matchmaker.
Naruto...
This old uncle can only help you this much.
If Toneri and Hinata become siblings in the future, then you'll have one rival less.
Now you can chase Sasuke with complete peace of mind.
As for Hinata...
She'll always remain your most reliable supporter.
