From beginning to end, Namikawa Yū had believed that Kaguya would never harm him.
That confidence had developed over their many years together.
Over those years, they had long since become the people closest to each other.
Anyone in the world might harm him, but Kaguya, standing before him, never would.
In the time that followed, Kaguya began preparing to implant Karma.
As an important means of reincarnation for the Otsutsuki Clan, Karma could not be implanted carelessly, and its host also had to be chosen with care.
Without sufficient tolerance for the Otsutsuki Clan's chakra, a person could not withstand the power of Karma at all. A single misstep could cause their body to collapse and kill them on the spot.
In this respect, Namikawa Yū's basic condition was not particularly good.
Fortunately, his body had been nourished by Otsutsuki Kaguya's chakra for years, giving him some degree of tolerance for her chakra.
Even so, implanting Karma did not go smoothly.
Only after considerable effort did Kaguya manage to implant an incomplete Karma within Namikawa Yū.
For Namikawa Yū, this was already his limit.
If they went any further, his body would collapse.
"So this is Karma?"
Standing where he was, Namikawa Yū raised his hand.
An incomplete diamond-shaped mark appeared on his palm. It possessed a distinctive beauty, looking quite unique and brimming with an air of mystery.
With Karma implanted, an aura similar to Otsutsuki Kaguya's began to emerge from him.
Kaguya's power was reshaping his body, bringing about changes within him.
He became younger, as though he had returned to his youth.
Even Kaguya, standing before him, was somewhat surprised by this change.
Fortunately, everything went relatively smoothly, without too many unexpected developments.
Once the entire process was over, she let out a long sigh of relief as well.
"I have a feeling..."
Standing where she was, she looked at Namikawa Yū before her and murmured, "Our child will be born soon..."
Perhaps it was due to the nature of the Otsutsuki Clan, or perhaps it was because Kaguya had swallowed the Chakra Fruit, but her pregnancy lasted far longer than expected.
Ten years had already passed since then, yet Kaguya still had not given birth.
Now, however, Kaguya finally had a premonition.
Her child was about to be born. It would not be much longer.
"The baby will be born soon?"
Hearing Kaguya's words, Namikawa Yū nodded, a smile appearing on his face.
Barring any unforeseen circumstances, the child in Kaguya's womb would be the future Sage of Six Paths.
It was remarkable to think about.
In the Ninja World where his original body resided, the Sage of Six Paths was an unquestionably towering figure to him.
Yet in this present world, the Sage of Six Paths was his future child.
Some things were simply that peculiar, leaving one with an indescribable feeling.
Namikawa Yū reflected inwardly as various thoughts flashed through his mind.
Time continued to pass, flowing slowly onward.
The following year, Kaguya went into labor.
After a night, she gave birth to two baby boys.
Following the Otsutsuki Clan's naming conventions, she named the two children Hagoromo and Hamura.
They were the future Sage of Six Paths and Hamura Otsutsuki.
When the two children were born, Namikawa Yū took some time to observe them closely.
Hagoromo, the future Sage of Six Paths, had only ordinary eyes, not the Rinnegan.
This differed from what was recorded in the canonical story, further supporting Namikawa Yū's conjecture about parallel worlds.
In the canonical storyline, Hagoromo Otsutsuki should have been born with the Rinnegan.
Perhaps this difference arose because, in the canonical storyline, Otsutsuki Kaguya had conceived the Sage of Six Paths alone, giving him a pure Otsutsuki bloodline.
In this world, however, Hagoromo Otsutsuki was born to him and Kaguya and possessed mortal blood, resulting in this change.
As for Hamura, he had inherited Kaguya's Byakugan.
Both children possessed tremendous potential within them.
Originally, having a mortal father like him should have diluted the two children's bloodlines to some extent.
However, because Kaguya had swallowed the Chakra Fruit while carrying them, they had also benefited, each gaining immense potential.
Although they looked unremarkable at present, the potential within them was tremendous. Once fully developed, they would be no weaker than the direct bloodline of the Otsutsuki Main Family.
"These two children have each inherited a portion of my abilities."
Before him, Kaguya gazed at the two children and spoke.
Both Hagoromo and Hamura had inherited Kaguya's pure Otsutsuki bloodline and were Otsutsuki by birth.
The abilities they had inherited from Kaguya were simply different.
As the elder brother, Hagoromo had inherited more of the power within Kaguya that came from the Chakra Fruit. Thus, his Byakugan remained hidden, and there was a strong possibility that he could awaken the Rinnegan in the future.
As the younger brother, Hamura had inherited the pure Otsutsuki bloodline within Otsutsuki Kaguya. Thus, he was born with the Byakugan, and in the future, he might advance beyond it and evolve the Tenseigan, which was extremely rare even within the Otsutsuki Clan.
"Thank you for everything."
Setting the two children down, Namikawa Yū walked up to Kaguya and drew her into his arms.
The two of them enjoyed those days together, quietly letting them settle within them.
In the days that followed, time passed slowly.
After the Hagoromo Brothers were born, the entire Land of Ancestors celebrated.
Celebrations were held throughout the land, rejoicing that the king now had heirs.
In the blink of an eye, more than a decade passed.
The Hamura Brothers gradually grew up.
As time passed, their bodies grew, and their strength increased at a rate far beyond that of ordinary people.
Because they possessed Otsutsuki blood, their power increased daily even without active training or study, and they were naturally far stronger than others.
Moreover, unlike their mother Kaguya, as Namikawa Yū's children, they were eager to learn and worked hard.
Their innate gifts surpassed those of ordinary people, and they were diligent enough themselves, allowing them to grow at an astonishing pace.
In just over a decade, they had become powerful by worldly standards.
Throughout the Land of Ancestors, no one was their match apart from a handful of people, including Kaguya.
One day, they came to the palace in the royal capital of the Land of Ancestors and sought out Namikawa Yū.
"You want to go out and train?"
Inside the palace, Namikawa Yū was still handling affairs of state. Hearing the news from Hamura and his brother, he looked up in surprise.
"Yes, Father."
Before Namikawa Yū, the Hagoromo Brothers were very respectful.
"You once said that things only have meaning when put into practice. We've studied in the palace for many years, and we feel it's time to go out and see the world."
Hagoromo spoke loudly, displaying great enthusiasm.
Compared with him, his younger brother Hamura at his side seemed much more composed, but he shared the same view.
