Sengoku woke to the lingering image of a blinding white light. In his recurring dream, the flash always tore through the sky, reducing a vibrant blue planet to ash. The apocalyptic vision shattered as he opened his eyes, fading into the rough, uneven stone ceiling of his bedroom. A wave of dizziness washed over him as reality settled in.
It was late June, Year Ten of the Ninja World.
Pushing open the heavy stone door, he was greeted by a gust of dry, dust-laden air that immediately stung his cheeks. Squinting against the early morning glare, Sengoku watched figures dart across the distant rooftops. Some carried grotesque, articulated puppets on their backs, while the ubiquitous hourglass symbol marked the village's identity. He was in Sunagakure—the Hidden Sand Village.
For months, his knowledge of this world had existed in his mind like shattered glass. His past life—more than twenty years on Earth—had violently collided with his present reality as a six-year-old orphan. Only in the last few days had the agonizing mental fusion finally settled. He was a transmigrator.
Yet, as he processed this reality, Sengoku found his own reaction unsettling. There was no panic, no thrill of a second life, not even a trace of anxiety. His mind was terrifyingly still.
At first, he had blamed this detachment on the dissonance of an adult mind trapped in a child's body. But a month ago, he had misplaced a protective amulet left by his deceased mother. A normal child would have cried; an adult would have felt a pang of sentimental loss. Sengoku had felt nothing. When he finally found it under his bed, the flicker of relief was so faint it vanished before he could even register it. It was then he realized the harrowing truth: the transmigration process had somehow stripped away his capacity to feel deep emotion. He was missing a fundamental piece of his humanity.
He returned to the dim interior of his home. Breakfast was a bowl of watery rice porridge and a piece of dried sand-worm meat so tough it threatened to chip his teeth. The village's meager orphan pension was barely enough to keep starvation at bay. The only way out of this squalor was tomorrow: the entrance ceremony for the Ninja Academy. Enrollment meant an immediate bump in food stipends.
While straightening his thin bedsheets, Sengoku's movements hitched. A strange, resonant tremor echoed deep within his soul. It wasn't painful—just a mysterious vibration that had been occurring intermittently ever since his memories fully merged.
Shaking it off, he pulled out his parents' old ninja tool bag. He checked every clasp and seam with practiced, mechanical efficiency. The canvas was bleached white by the harsh desert sun, but the stitching held firm. Kunai pouches, shuriken slots, and scroll cases—everything was intact.
The existence of a Ninja Academy told him something crucial about the timeline. Since Sunagakure had copied the academy system established by Konoha, he knew he was at least past the era of the Second Hokage, though whether the First Shinobi World War had already ended remained unclear.
He wasn't particularly concerned about the village's grim future. He knew the lore well: Sunagakure was destined to be the weakest of the Five Great Villages. Its Third Kazekage would eventually be murdered and turned into a puppet, the Fourth would be assassinated by Orochimaru, and the Fifth would be abducted from his own office.
But Sengoku's ambitions stretched far beyond these sand dunes. His awakened memories held the locations of this world's greatest hidden powers. The Dragon Vein beneath Rouran that could bend time; the earth-shattering energy of the Gelel Stone; the world-ending demon Moryo sealed in the Land of Demons; and the autonomous puppet army and colossal Tenseigan waiting on the moon. The academy was merely his first stepping stone toward claiming those extraordinary forces.
"Look at this! Wind Release: Great Breakthrough!"
A childish shout drifted through the window. Outside, a red-haired boy puffed his cheeks and blew hard, trying to mimic a jutsu. Instead of summoning a gale, he only kicked up a cloud of dust, sending himself into a fit of coughing while his friends erupted in laughter.
Sengoku stood by the window, watching them with a quiet, unblinking gaze. The barrier of his past life made their innocent play feel utterly alien. The typical anxieties and excitements of starting the academy seemed profoundly naive to a mind that had already lived a lifetime.
He remained in his silent contemplation until the setting sun stretched the village's shadows long across the sand. The distant cheer of the children moved toward the central plaza, drawn by the traveling acrobats hired for the eve of the academy entrance. Sengoku didn't follow.
Returning to his bed, he unrolled the scroll case his parents had left behind. Inside lay their entire legacy: Chakra Thread Manipulation, Basic Puppet Crafting and Maintenance, Puppet Operation Technique, and two ninjutsu scrolls—Wind Release: Great Breakthrough and Wind Release: Wind Cutter.
He traced the kanji on the parchment. His six-year-old vocabulary was barely enough to decipher the titles; the intricate technical instructions inside were completely unreadable. He gripped the scrolls tightly, a pragmatic thought crossing his mind. He would learn to read properly at the academy. If his eventual chakra nature didn't turn out to be Wind, he could always use those two elemental scrolls as leverage to trade for jutsu that suited him.
Carefully stowing the legacy away, Sengoku watched night swallow the village. The haunting, melodic notes of a traditional Sunagakure flute drifted through the cooling air.
He checked the locks on his door and windows, blew out the flickering oil lamp, and lay back in the dark. Tomorrow, he would officially step into the shinobi world. He closed his eyes, commanding his mind to sleep.
