Just as Tsunade expected, after Uchiha Shin informed Kaguya Otsutsuki about the death of Isshiki Otsutsuki, she was beyond elated.
Princess Kaguya was so delighted that she obeyed Uchiha Shin in everything, like a pampered cat.
Uchiha Shin stayed in her palace for three full days and nights before finally managing to escape—barely.
But even after he returned, Kaguya still showed no signs of coming out.
On one hand, she had grown used to the luxurious lifestyle in the palace. With TVs, computers, and other Earthly entertainment, she was gradually turning into a shut-in princess.
Uchiha Shin genuinely felt she was slowly transforming into a NEET—an Otsutsuki NEET.
On the other hand, her body was weak. Despite her enhanced recovery abilities, Kaguya was significantly affected by Shin's... vigorous application of the Sage Seal.
The mental and physical shock left her unconscious more than once. Her chakra pathways were robust but not that robust.
Returning to Tsunade's side in high spirits, Uchiha Shin was immediately drawn into a massive "group brawl."
The only regret? Mikoto, Kanako, Kushina, Karura, and the rest were unable to join the battle. Their bodies were "busy" in other ways.
They contributed by... making special beverages and managing logistics.
After tasting the handmade drinks brewed by Mikoto and the others, Shin estimated—through experience—that it was about time.
Sure enough, less than two months later, the blessed news arrived. Mikoto and her friends gave birth to daughters.
Mikoto's daughter, named "Uchiha Yumi," was a joint decision between her and Shin.
Kanako's daughter was named "Uzumaki Karin," while Kushina named hers "Uzumaki Mina."
The names were a blend—Kushina and Mikoto shared a strong friendship, so the children's names took a kanji from each.
Karura, having conceived a bit later, gave birth after the others. Her daughter was named "Temari," echoing strength and elegance.
Seeing her new siblings, Sara felt a mix of emotions—mainly pride.
Sure, her love had been "shared," and that stung a bit.
But she was still the eldest, and that gave her a huge advantage.
She adored her younger sisters and relished in the chance to be their mentor—and occasionally brag.
Tsunade, who had overseen all the deliveries, had become increasingly envious.
Despite trying repeatedly, she hadn't gotten pregnant.
Why? Because Uchiha Shin's body had evolved too far beyond human biology.
His life force and chakra density were now in a realm similar to the Otsutsuki. Fertility became... problematic.
Later, they learned from Kaguya that this was a common issue in the Otsutsuki clan.
Due to their karma-bound existences and massive chakra stores, they rarely procreated naturally.
Most Otsutsuki were either ascetics or used Yin-Yang Release to create life, just as Kaguya had done.
Pregnancy? That could take thousands of years.
When Tsunade heard that, she nearly had a stroke. Thousands of years? That was like dying of boredom ten times over.
Kaguya, however, was baffled by Tsunade's reaction. To her, a thousand years was like a long nap.
Due to Shin's bloodline influence, Tsunade and the others had now achieved near-immortality. Their lifespans were essentially endless.
Even without consuming a Chakra Fruit, Shin's mutated genetics had extended their lives exponentially.
Kaguya mentioned she had never seen an Otsutsuki die of old age.
Tsunade eventually accepted it—but not without some serious drinking sessions.
She preferred natural pregnancy. Yin-Yang Release and clone births didn't appeal to her.
Most of the others agreed. Their values weren't fully aligned with Kaguya's, who treated reproduction like a science project.
Uchiha Shin didn't force his ideals. He let everyone choose freely.
But he had a growing concern. With so many daughters already, how was he supposed to support them all?
They were his little princesses, his cotton-padded jackets. Raising even one was a mission. Raising a horde? That was a saga.
Recently, Shin had focused more on world integration.
He had merged multiple dimensions into a pocket universe—large enough to host an entire galaxy.
He could even transplant Earth, the Moon, and the Sun into this small world.
This would save him from creating artificial celestial light sources, though he still had to calculate orbital balances.
Gravitational dynamics between celestial bodies needed careful handling to ensure ecological survival.
If he didn't have complete mastery over the space, this project would've taken millennia.
But now, he was gradually expanding his small world—engulfing nearby star systems.
"We're about to spring the trap. The higher-ups of the Otsutsuki clan have sent envoys," Shin muttered, staring into the cosmos.
If the Otsutsuki could sense chakra waves from Earth, then surely he could sense them from light-years away.
Over the years, he had evolved the clairvoyant dojutsu from Shibai's technique—enhancing it far beyond its original parameters.
Even from Earth, he could now witness events occurring dozens of light-years away.
With proper focus and enough chakra, the range expanded tenfold.
"I've more or less mastered the reactive kill zone now," he said.
"But Shibai's ultimate dojutsu—[Omnipotence]—still escapes me."
Murmuring to himself, Shin teleported into a hidden lab deep beneath the palace.
This was his personal sanctuary, dedicated to the most delicate of experiments.
Suspended in a nutrient-filled pod was a girl—a clone.
She was created using Otsutsuki Shibai's genes, enhanced with Orochimaru's cellular regeneration techniques and Amado's modified cloning tech.
The girl had long, ocean-blue hair that curled into rings, with streaks of pale pink. Her eyes were sapphire, and twin black beauty marks sat beneath them.
Her body was flawless—porcelain pale, sculpted like a divine statue.
"Ada…" Shin whispered. "She inherited the [Clairvoyance] and [Omnipotence] abilities."
From her, he hoped to better understand Shibai's most enigmatic technique.
He folded his arms and looked at the floating girl.
As if sensing his presence, Ada's eyes fluttered open. Her gaze, deep and captivating, locked onto Shin.
A gentle smile formed across her delicate lips as she reached out, her tiny hand pressing against the glass.
Moved, Shin stepped forward and mirrored her gesture, placing his palm where hers met the container wall.
"Just a little longer, Ada," he said softly.
"Your body still needs tuning. Stabilization of your genetic matrix is crucial."
Ada continued smiling, her aura gentle but eerie—like an ancient goddess waking from slumber.
"Don't worry, I'll visit you every day. I promise," Shin murmured.
Ada had been rapidly matured through chakra acceleration and medical jutsu. Without it, she wouldn't appear as an 18-year-old so quickly.
Still, Shin didn't cut corners. He worked meticulously, stabilizing her DNA, checking for irregularities, minimizing risks of mutation or sickness.
In this one girl, he saw the potential to unlock the final secrets of Shibai's legacy.
Ada wasn't just a clone. She was a key.
And soon… she'd be awake.
Fully awake.
