The ocular technique in Hagoromo's Rinnegan was special.
It was a seal he had prepared well in advance.
Six Paths-Planetary Devastation.
Even ordinary Planetary Devastation was an extremely powerful sealing technique, but the technique Hagoromo had prepared now took it to the extreme, requiring him to expend all the chakra in his body at once to cast it.
With such an enormous cost, its effects were naturally astonishing. In theory, this technique was powerful enough to create another miniature celestial body and seal everything within it.
Hagoromo had developed this technique specifically to seal his mother, Otsutsuki Kaguya.
As someone who had consumed the Chakra Fruit, Otsutsuki Kaguya could, in a sense, be considered immortal.
There might have been limits to this immortality, but with Hagoromo and Hamura's current strength, killing her completely was absolutely impossible.
Thus, sealing her was the only way to eliminate this threat.
Six Paths-Planetary Devastation was the cage Hagoromo had prepared for Kaguya. As long as they sealed her away, everything could end.
No matter how powerful Kaguya was, she could not possibly break free of this technique's restraints while being suppressed by the Hagoromo Brothers.
And now, the opportunity had appeared...
As long as I cast this technique, everything will be over... The thought flashed through Hagoromo's mind. A faint light flickered in his purple Rinnegan as he was about to activate the technique within them.
At that moment, however, something unexpected happened again.
In the sky ahead, Namikawa Yū suddenly appeared beside Kaguya.
Standing beside Kaguya, he gently reached out and drew her into his arms, smiling at the two children before him.
"Father!"
At the sight before them, Hagoromo and Hamura's expressions changed drastically in an instant.
Deep hesitation appeared on Hagoromo's face. He remained where he was for a moment, frozen.
At that moment, his emotions were complicated, and many, many thoughts passed through his mind.
"Father, did you even anticipate this?"
Finally, he let out a long sigh and ultimately did not strike.
Attacking Kaguya was different from attacking Namikawa Yū.
To the Hagoromo Brothers, although Kaguya was their mother, she had always been aloof and distant. They felt little burden in attacking her to save the world.
But Namikawa Yū was different.
He was their father, who had approved of the path they followed from beginning to end, and the person they admired and revered most.
Attacking their own father was utterly impossible for them.
Father, would you rather resort to this than let us attack Mother?
Beside him, this thought flashed through Hamura's mind. He too let out a long sigh and abandoned his intention to attack.
The two left Sage Mode and returned to their normal states, then came before Namikawa Yū and Kaguya.
Beside him, Kaguya watched the approaching Hagoromo Brothers. A fierce gleam flashed through her Byakugan, and she still wanted to continue fighting.
Namikawa Yū caught her hand in time and shook his head at her, stopping her from taking any further action.
"Now that things have come to this, let's leave it here."
He looked at Kaguya before him and said softly, "Have you forgotten our earlier agreement?"
Namikawa Yū's words reminded Kaguya.
Before this, she had made an agreement with Namikawa Yū: if she proved no match for Hagoromo and Hamura, she would obediently listen afterward and not interfere with anything else on her own.
And now, clearly, it was time to honor that agreement.
However proud she had been before, faced with the present situation, she could not deny that she truly was no match for the Hagoromo Brothers.
In terms of strength, neither of them was weaker than her. They were merely somewhat inferior in the quality and quantity of their chakra.
But their mastery of natural energy made up for this well, allowing them to wield power no less than Kaguya's and reach their current level.
She looked at Hagoromo and Hamura before her, then at Namikawa Yū beside her, who was watching her with a smile. In the end, she gave up on letting go and did nothing more.
Only then did Namikawa Yū breathe a sigh of relief.
It's good that she can face reality. At least she knows when to back down.
The real concern is being weaker than someone else yet refusing to back down, insisting on fighting to the bitter end.
In that case, even Namikawa Yū would have been helpless.
After all, he could not simply watch Kaguya drain this world dry.
In his eyes, this world's value was greater than that of a single Chakra Fruit, no matter what.
As long as the world remained, natural energy could continue to arise endlessly and nurture many Chakra Fruits. There was no need to rush.
Of course, aside from dealing with future enemies from the Otsutsuki, Kaguya was in such a hurry mainly because of Namikawa Yū.
As the power of Karma continued to merge with him, his physical condition grew worse and worse. If this went on, something bad would happen sooner or later.
It was precisely because Kaguya had noticed this that she had begun to grow anxious.
But Namikawa Yū knew that her anxiety was meaningless.
The time for his reincarnation had come. Even if that Chakra Fruit ripened now, it would not be able to keep him here.
Moreover, judging by the current situation, that Chakra Fruit clearly still needed a long time to ripen.
For precisely this reason, he had deliberately arranged this meeting, bringing the conflict between Hagoromo and Hamura and Kaguya to a head ahead of time.
With him here, there would at least be some room to maneuver.
"Let's stop."
He beckoned to Hagoromo and Hamura, his manner as gentle as ever.
Hagoromo and Hamura hesitated for a moment, but ultimately chose to step forward and follow Namikawa Yū away.
They returned to the palace, where Indra and Asura came to greet them.
"Father!"
Asura was the first to come forward, looking quite excited. "Were you fighting Grandmother just now? That was amazing!"
His face was filled with excitement and admiration. He simply thought Kaguya and the Hagoromo Brothers had been sparring and envied their power.
Indra beside him was much more perceptive and had already vaguely realized that something was wrong.
But he said nothing more, merely standing silently to one side and watching them with a somewhat nervous expression.
"Yes."
Namikawa Yū stepped forward with a smile, patted Indra and Asura on the head, and said softly, "Your father and uncle were fighting your grandmother just now. It seems they caused a bit too much of a commotion."
"But fortunately, no one came to harm. You can rest easy."
He sent the two children off, then led Hagoromo and the others deeper into the palace.
"I'm leaving."
Looking at Hagoromo and the others before him, Namikawa Yū suddenly spoke.
At these words, Hagoromo and the others before him were immediately stunned, already realizing the meaning behind Namikawa Yū's words.
"Father, where are you going?"
Hamura was the first to speak, looking somewhat anxious. "Did we do something wrong?"
"Father, don't abandon us."
Hagoromo spoke as well, his expression tense. "The Land of Ancestors cannot lose your leadership."
Kaguya beside them said nothing, but she too turned her gaze toward him, her eyes filled with tension.
"The Land of Ancestors has already matured. Whether I'm here or not makes no difference to most people in this country now."
Namikawa Yū smiled as he spoke. "Besides, you've grown up now too."
"For new trees to grow strong, they always need enough space. If I kept standing in your way, it would be rather unfair to you after all your hard work."
"Your abilities now are also enough to put my mind at ease."
He looked at Hagoromo and Hamura before him, his eyes filled with profound expectations.
"Father..."
Meeting Namikawa Yū's gaze, both Hagoromo and Hamura were moved, unsure what to say.
"The same goes for you, Kaguya."
Namikawa Yū turned to look at the wife who had been by his side for so many years, the smile on his face unchanged. "I've been very happy all these years with you, and I'm very glad I was able to meet you in this life."
"So, while I'm away, I hope you'll live well and get along well with the children too."
Holding Kaguya's hand, he murmured softly, "They are your children, after all. They may sometimes fall short of your expectations, but that is all an inevitable part of growing up."
"There's no need to be sad about it. Just wait for me to return."
"Yū..."
Meeting Namikawa Yū's gaze, Kaguya opened her mouth as though she wanted to say something, but in the end, she said nothing.
