Transmigrated as Uchiha, Starting as 'Cannon Fodder'
Konoha, Year 50.
Land of Fire.
Ninja Academy, Fifth Year, Class B.
"First of all, congratulations to everyone."
"From today onward, you have officially become Genin of Konohagakure."
"Where the leaves dance, the fire will burn. As long as there are leaves to dance, the fire's light will guide the village and help new leaves to sprout."
…
On the podium stood Sarutobi Takeo, wearing a Chunin's standard flak jacket, shouting loudly to inspire the graduates.
Below the stage, dozens of excited Academy students adjusted their new Konoha headbands, their faces brimming with pride. For civilian-born students, becoming a ninja was a dream come true.
But the heirs of the major clans didn't look nearly as excited. Most wore frowns, their eyes calm or calculating.
In the back row, seated near the window, a pale-faced boy with a frail build let out a quiet sigh.
His clothes bore the Uchiha crest — the red-and-white fan that made his identity clear.
Yes.
His name was Uchiha Jin — a member of the Uchiha clan.
And, more importantly, he was a transmigrator.
"Ah… what a headache."
"I was hoping to delay graduation until next year. But no — Hiruzen just had to conscript even the fifth-years. Guess the front lines must be running out of warm bodies…"
Jin was twelve years old this year — the same age as Hatake Kakashi.
As for Uchiha Itachi, Konoha's so-called prodigy and eventual clan-slayer, he was only four years old right now — still running around the compound under Fugaku's stern eye.
Jin had been living in this world for nearly eight years now. No cheat system. No golden finger. Just his own wits, and a family that… no longer existed.
His parents had once been loyal followers of Uchiha Kagami — the brilliant Uchiha who was also a close friend of Sarutobi Hiruzen. When Kagami died during the Second Great Ninja War, his loyalists, including Jin's parents, lost favor with the main clan and were politically isolated. A few years later, they both died in an "accident" during a mission.
Jin knew better — it had been a quiet purge by the radical Uchiha faction.
So now, he was in a miserable position:
Distrusted by the Uchiha clan.
Unable to approach the Hokage faction.
And, effectively, an orphan.
If not for the inheritance his parents left behind, he would have been starving.
At least his talent wasn't weak.
Thanks to the scrolls his parents left him, Jin had mastered more than the Academy basics. In addition to the Clone, Transformation, and Substitution Techniques, he had learned five Fire Release jutsu:
C-rank: Great Fireball Technique, Phoenix Sage Fire, and Flame Bullet
B-rank: Great Fire Destruction and Fire Release: Violent Wave
And that was just what he dared to practice in private.
His greatest trump card?
His Sharingan — already fully matured to Three Tomoe.
With that, Jin was confident that even against Hatake Kakashi — who had just been promoted to Jonin — he could at least hold his ground.
But showing that much talent would only drag him deeper into clan politics, and Jin had zero interest in that.
The Uchiha were doomed.
Sooner or later, they would be wiped out by Itachi under orders from Hiruzen and Danzō.
And Jin had no intention of dying with them.
Trying to "save the clan" sounded noble, but in reality? Impossible. The Uchiha were too proud, too divided, and too blind to the fact that they were already surrounded by enemies.
Uchiha Fugaku, their leader, was nothing more than a passive compromiser. He had awakened the Mangekyō Sharingan, yet never used it decisively. He couldn't stop Danzō's surveillance, couldn't control the radicals in his own clan, and couldn't even raise his own son in a way that would prevent him from becoming the Hokage's executioner.
In short: the Uchiha were a sinking ship.
And Jin had no emotional reason to try to fix it.
So he made up his mind — stay quiet, grow stronger, and when the night of the clan massacre came… leave the village.
Until then? Just lay low.
Even though he had the strength of a Jonin, he had deliberately stayed in the Academy to avoid attention.
But fate wasn't going to give him a chance to hide any longer.
The Third Great Shinobi War had broken out.
The Third Kazekage had vanished, and Sunagakure, blaming Konoha, launched a full-scale invasion.
Iwagakure and Kumogakure quickly followed, seizing the opportunity to attack the Land of Fire from other fronts.
Even Kirigakure was reportedly preparing to strike while Konoha was weakened.
And so, with manpower stretched to the breaking point, even twelve-year-old students were being pushed to the front lines.
