Chapter 2: Calculated Entry
Konoha, Year 37 (15 Years Before the Nine-Tails Rebellion)
Uchiha Clan Territory
In a spacious, traditional Japanese-style house located in the inner circle of the Uchiha clan compound, a woman was busy doing household chores. Her name was Ren Uchiha.
Just then, a man approached her from behind, gently placing his hand on her stomach. He softly stopped her movements and said,
"You shouldn't be working in your condition. The house helpers will take care of everything."
Ren turned toward him with a warm, loving smile and replied,
"I'm fine. You know I enjoy doing little things around the house."
The man's name was Kaito Uchiha—an elite jonin of the Uchiha clan with fully matured three-tomoe Sharingan. He was the son of Setsuna Uchiha, the clan's First Elder, and a strong candidate for the future clan head. Ren, his wife, was also a jonin with three-tomoe Sharingan and had recently become pregnant. According to the due date, she was expected to give birth about a month after the New Year.
As the couple exchanged words with affection, a faint consciousness began to awaken within Ren's womb.

Inside the Womb
The soul of our main character stirred.
There was darkness—not the endless void he remembered from before, but the muted kind that came from undeveloped senses. The surrounding womb was warm and quiet, the world a dull hum of vibrations and muffled sound.
After a month of this embryonic existence, his recently awakened [ All of Existence ] sub-skill, now refined by the void's endless pressure, began to yield results. He could sense faint, muffled vibrations that coalesced into rudimentary auditory and visual data, much like an advanced form of echolocation. It allowed him to map his immediate surroundings within a ten-meter radius. He processed the fragments of muffled conversations, the faint scent of traditional wood and paper, the rhythmic beat of Ren's heart, and the nuanced chakra signatures of those around her.
His internal calculations, honed over unknowable eons of self-optimization, rapidly sifted through the data. He deduced, with stark clarity, that he had been reincarnated into the Uchiha clan. More precisely, as the grandson of the First Elder, Setsuna Uchiha. And Kaito, the man whose robust chakra signature he frequently sensed, was to be his father—the designated heir to the clan's leadership.
A flicker of a cold, analytical doubt surfaced. Kaito Uchiha was never the clan head in the original timeline, he mused, accessing the vast, almost infinite data stream of his past life's knowledge. This is clearly an alternate universe. The thought was not one of surprise or alarm, but rather a prompt for intensified observation. He mentally flagged this discrepancy, recognizing it as a critical variable in his future calculations. From then on, every scrap of information gathered from the muffled outside world was processed with heightened scrutiny, particularly concerning the clan's hierarchy and political landscape. His own developing body, thanks to the constant, adaptive optimization of [ Evolution Singularity ], was growing healthy and strong, already subtly reconfiguring itself to the new environment.

Back in the Outer World
As time passed, Ren's belly grew. Occasionally, she would gently talk to her unborn child, caressing her stomach with a bittersweet smile.
One day, a sense of unease crept into her heart without explanation. That evening, Kaito returned home with a serious expression.
"I have to go on a scouting mission near the border," he said. "There's been movement from Sunagakure. The Second Ninja War might break out any day now."
Ren's face paled.
"Can't you stay? Please..." she pleaded softly.
"I wish I could," he replied. "But this mission is important. Once I become the clan leader, I won't have to go on missions like this. But until then…"
Despite her worries, she knew she couldn't stop him. He was too dedicated—both to the clan and the village.
Before departing, Kaito tried to reassure her, perhaps more for himself than for her. "And you know how powerful I am, Ren. I'm not alone. It's a full team: one from the Uchiha, one from the Sarutobi clan, and one from the Shimura clan. Four of us. We will be able to escape if anything goes awry."
He smiled, a confident, if strained, smile.
After a long, silent moment, Ren offered a reluctant nod, her eyes downcast. She said nothing further, the knot of unease tightening in her gut.

One Week Later
Setsuna Uchiha arrived at Ren's home, his face clouded with grief. The moment she saw him, her heart sank.
"Kaito… is gone," Setsuna said with a heavy voice.
Ren froze.
"It was a trap," he explained. "The movement at the border was staged by Sunagakure… But we believe the real trap was set by the Third Hokage and Danzo. They had intel long before the mission, yet they sent Kaito anyway—most likely to eliminate him, and with him, the radicals' growing influence."
Ren felt her knees give out as the world crumbled around her.
Setsuna clenched his fists. "I cannot prove anything, not now. And with war looming, we cannot retaliate. I… I'm sorry, Ren."

Within the Womb
The main character received the news through his spiritual perception.
He understood now.
This was the reason Kaito had never become a clan head. This was why the Uchiha radical faction had been so enraged with the village leadership. Setsuna, the First Elder and now the head of the radicals, had lost his only son—their great hope for change. The betrayal had planted the seeds of rebellion deep within the Uchiha.

Uchiha clan funeral
Ren, Kaito's wife, attended the grim funeral in a daze. She saw his body, the obvious sword wounds and shrapnel from kunai on his chest and front. But then, a chilling detail: the poisoned senbon embedded in his back, subtly concealed. And the clear signs of friendly fire among the debris. He hadn't died because he was weak, or solely because of the enemy. He had died because he was betrayed by his own teammates, caught between their treachery and the enemy's onslaught. The truth, cold and sharp, lacerated her soul.
His mother changed after that day.
She stopped leaving the house. She avoided everyone—even Setsuna. She sat in silence, speaking only occasionally to the child within her, voice strained by grief.
She had loved Kaito with her entire being. And now he was gone.
She blamed herself.
Her depression was deep, paralyzing, suffocating. But she still clung to her unborn child.
From the quiet, dark sanctuary of her womb, our character observed his mother's emotional breakdown. It was a phenomenon to be cataloged, its progression noted. He felt no empathy, no grief. Only a stark, almost clinical understanding of the new, treacherous landscape into which he was to be born. His lineage was one of betrayal, political machinations, and simmering resentment. A perfect environment for a being who understood only cold calculation and self-preservation.
