Chapter 1, Rebirth of the Analyzer
Darkness.
That was the first thing he remembered. Not pain. Not fear. Just a thick, suffocating blackness. Then awareness came, sudden and jarring. Something clicked into place.
Kazuki Kurogane's eyes opened.
The world around him was blurry. Colors faded from morning fog and dirt-covered windows. He blinked a few times, his heart thumping quietly in his chest, as scattered thoughts swirled through his mind like dust in the light.
The ceiling above him was cracked and peeling. The smell of old wood and damp fabric filled the air. Nearby, a child coughed. A door creaked. Birds chirped outside these walls.
He sat up.
The bed beneath him was small and uncomfortable. A worn blanket barely clung to his legs. The room was cramped, shared with several other children, all curled up on old mattresses and secondhand sheets. The floor felt cold on his bare feet.
He knew this place.
No, Kazuki didn't. But the boy whose memories now filled his mind did.
"This isn't Earth."
The words escaped his lips in a whisper, shaky and uncertain. He didn't recognize his own voice—it was soft and higher-pitched. A child's voice.
His hands shook as he raised them to his face. Small. Pale. Fingers made thin by mild malnutrition. He scrambled off the bed and rushed to the cracked mirror near the bathroom sink, ignoring the curious glance from a half-asleep boy in the next bed.
The reflection didn't lie.
A five-year-old boy stared back. Dark hair, cut unevenly. Hollow cheeks. Eyes too tired for someone so young. There were traces of his old self in those eyes, but they were buried beneath the weight of this new reality.
"No. No, no, no."
He stumbled back, hitting the edge of a wooden dresser. His breathing quickened. The memories—the truck, the voice, the void—all came rushing back like a wave.
The voice of the man in the void.
"Call me R.O.B. Random Omnipotent Being. You've read enough fanfics to know what comes next."
"You're going to the Naruto world."
"One cheat. One gift."
"AI Chip, just like Warlock of the Magus World? Interesting choice."
Kazuki froze. The room spun. His knees buckled, and he collapsed onto the floor.
This wasn't a dream. It wasn't a hallucination.
This was real.
He had died.
He had been reborn.
And now he was in the Naruto universe. In the body of a nameless orphan without a clan.
His heart pounded in his chest like a war drum. A thousand possibilities flooded his mind. Jinchūriki. Akatsuki. Wars. Genocide. Moon-blasting gods. This world was beautiful but also cruel and merciless.
And he was five years old. Alone and powerless.
[A.I. Chip, Core Systems Initializing...]
[Synchronization: 73%... 89%... 100%]
[Core Functionality: Level 1, Active]
Kazuki flinched. The words appeared not in front of his eyes but in his mind—clear, mechanical, and artificial. An interface he couldn't touch but could feel. The first digital voice he'd heard in this new life.
The cheat.
[Welcome, Host. AI Chip synchronization complete.]
[Sensory Feed Stable, Beginning Passive Data Recording.]
A moment of silence followed.
Kazuki slowly lifted his head. His shaking stopped. His breathing steadied. The voice, though synthetic, was grounding and familiar. It felt like a lifeline back to his old self.
He was not just a child anymore. He had a purpose. A chance.
Still sitting on the floor, Kazuki looked around.
The room was quiet again. A couple of children stirred in their beds, stretching and yawning. Outside, an old bell rang twice—it was breakfast time. The routine in the orphanage was simple: wake, eat, clean, and wait. Wait for someone to adopt you or for the village to send you to the Academy when you turned six.
No one in this room knew they were living in a world ready to explode. No one else knew that ten years from now, monsters would walk the earth.
But Kazuki did.
And that knowledge settled heavily in his stomach.

The days passed slowly.
Kazuki kept to himself. He was quiet—too quiet for a child. But the caretakers didn't mind; he caused no trouble, and they found quiet ones easier to manage.
He spent most of his time watching.
Watching how people moved. How the staff acted. How the other children fought, cried, stole, and comforted each other.
The AI Chip didn't speak much. It ran in the background, recording everything he saw and heard. Occasionally, a flicker of data would scroll through his mind:
[Subject: Yui, 8 years old, Height: 118.6cm, Chakra flow: minimal, Signs of cold onset]
[Konoha Standard Language fully absorbed, Variants: Civilian Dialect, Early Shinobi Terminology (24%)]
It was eerie, silent, and helpful.
He hadn't started chakra training. Not yet. Something in him felt rushing would be a mistake.
He needed to understand his place here first. His surroundings. His limits. And most of all… himself.
Each night, he lay in bed, staring at the ceiling as the other kids fell asleep.
And each night, the same thought came:
"This isn't a game."
"This is the real Naruto world. With real people and real death."
"If I'm going to survive this, I need to be more than smart. I need to be patient."

By the seventh night, something in him shifted.
Not a dramatic revelation. Not a sudden flash of genius.
Just a quiet moment, sitting on the edge of his bed, feeling the wind blow through a cracked window.
He whispered to himself.
"I was reborn into one of the most dangerous worlds ever imagined."
He looked down at his tiny hands—flesh and bone, weak and soft.
"But I'm not starting from zero."
A faint, almost imperceptible ping echoed in the back of his mind as the chip responded.
Kazuki smiled faintly.
"Let's take our time. Build the foundation. One piece at a time."
He wasn't a prodigy.
He wasn't a chosen one.
But he was something else now.
Something this world had never seen before.
