Thousands of years ago, the world was a storm of endless war. Humans slaughtered humans, villages burned, and no peace seemed possible. It was dark. Brutal. Hopeless.
Until one man changed everything. The Sage of Six Paths. With power that could shake the heavens, he ended the wars and wove a thread connecting people's hearts — chakra.
Through this invisible energy, people began to understand each other. Peace took root, and those who could manipulate chakra called themselves the first shinobi. Ninja. Their name would echo through history.
But peace never lasts. Ashura and Indra, sons of the Sage, clashed, severing the threads of chakra and sending the world spiraling back into chaos. From that chaos, the ninja were born — masters of chakra, survival, and war.
During the Warring States Period, a shout cut through the hills in the southeast corner of the Land of Fire, near the Lake of the Sea.
Raizen's eyes flicked toward a cluster of wooden buildings tucked between the hills — a small settlement, simple, but alive. On a flat training ground, a handful of children, five to ten years old, were throwing punches, fists raised to the sky, sweat gleaming on their young faces.
This was the Amamiya Clan — a minor ninja family in the southeast. Small, with barely a hundred members, they survived in a brutal era by keeping their heads down and their chakra sharp.
Despite their size, the clan was legitimate. A handful of jōnin-level ninjas trained these children, ensuring the family stayed strong. Every child of five or older was put through the basics: physical conditioning and chakra refinement. The shouts came from that rigorous training.
"Eh!"
Raizen noticed a soft sigh from the corner. A small boy — black hair, sorrowful eyes — sat watching the others. Mutters escaped his lips, barely audible:
"Unlucky… cursed… why me, of all people?"
If one listened closely, they could catch him rambling about fate, dragons, and some ridiculous family he'd never heard of — clearly a modern soul trapped in a five-year-old body.
A middle-aged man in a training uniform frowned and approached, concern etched into his features.
"Raizen-kun, are you feeling ill? Should you rest?"
Raizen forced a smile. "I'm fine, Uncle Yamamoto. Just a little dizzy."
"Good… your father, Kiyomasa, sacrificed much for the clan. Once you recover, you'll train as a ninja and inherit his legacy!"
Yamamoto gave him a firm glance, patted his head, and walked back to the training field.
Raizen exhaled, relief washing over him. Uncle Yamamoto was the clan's chūnin and Raizen's instructor, and his father, Amamiya Kiyomasa, had been a respected ninja who doted on his only son.
But everything had changed. Just days ago, Kiyomasa was killed on a mission by a hostile family. The original body of Raizen — a young man from the modern world — had died of grief. And now, Raizen woke up in the body of this boy, in a chaotic ninja world he only vaguely recognized: Naruto's world.
Raizen groaned inwardly. Great. I wake up as a five-year-old in a "soy sauce" ninja family, centuries before Konoha even exists.
The only silver lining? His chakra was enormous, and he possessed all five elemental affinities — a cheat even in this era. Maybe I still have a chance to touch something legendary… if I don't die first.
Even without bloodlines or secret arts, the Amamiya Clan was said to be the most chakra-rich family of the Warring States Period — surpassing even the legendary Uzumaki and Senju. Raizen had barely started chakra refinement, and already he felt like a full chūnin-level ninja.
No wonder they've survived this long without fancy jutsus. In battle, raw chakra and determination can stack victories like bricks.
A distant voice shattered his thoughts.
"The distinguished guests from the Uchiha Clan have arrived!"
Raizen looked up. The patriarch, Amamiya Gen, led a procession toward the gates. His heart sank slightly — alliances with powerful families always came with strings attached. But one thought gave him a spark of pride: With my chakra, even a small family like Amamiya can punch above its weight… eventually.
