Synopsis:
Reborn as an ordinary genin of the Uchiha clan, Ryuu had resigned himself to living out a quiet, unremarkable life — until he found himself bound to a Check‑in System.
– Check‑in at Kannabi Bridge: Reward received — Rinnegan
– Check‑in at the Hokage Building: Reward received — Flying Raijin Jutsu
– Check‑in at the Valley of the End: Reward received — Sage Body
…
With the resolve that he would not step into the wider world until he reached the Six Paths level, Ryuu kept checking in quietly within Konoha.
Ten years later, the village made the decision to wipe out the entire Uchiha clan — and Ryuu was forced to act.
Chapter 1:
Year 47 of Konoha.
Kannabi Bridge.
As far as the eye could see, the area was filled with crumbling walls and scattered rubble.
The ground was pocked with deep craters left by powerful ninjutsu, some still wisping with faint smoke.
A cold mountain wind swept through every now and then, making the sharp, metallic stench of blood hang even heavier in the air.
It was clear at a glance: a brutal battle had only just ended here.
Amidst the desolate battlefield, seven or eight figures stood before a massive pile of boulders and debris.
Every single one of them was a Konoha ninja.
Most wore emblems stitched clearly to their clothes — the mark of the Konoha Military Police Force.
Yes, these were almost all members of the Police Force.
More precisely, they hailed from the Uchiha clan of Konoha.
Normally, the Police Force was tasked with maintaining order within the village — but the Third Great Ninja War was raging at full force, and Konoha was drastically short on manpower.
Even fresh graduates from the Ninja Academy had been sent to the front lines.
Naturally, the Military Police Force had been deployed as well.
“Kakashi… is this the place?”
Uchiha Shisui, leading the team, glanced over the scene and turned to ask the boy standing at the very front — the only one not of Uchiha blood.
The boy’s left eye was shut tight.
A jagged scar sliced right across the eyelid, clear proof that a blade had already blinded it.
This was none other than Kakashi Hatake — student of Minato Namikaze.
At his side stood another member of Team Minato: Rin Nohara.
The third member, Uchiha Obito, was nowhere to be seen — buried beneath the rubble before them.
Kakashi nodded.
“This is it.
Hurry — we need to dig him out quickly!”
“Move out!”
With a sharp wave of Shisui’s hand, the Police Force wasted no more words.
They stepped forward at once, hefting stones aside and digging with all their strength.
“Damn it — Obito just died, and the Battle of Kannabi Bridge just ended… Why the hell did I wake up in such a messed‑up time?!”
No one knew that one of the Uchiha clansmen hauling stones was inwardly seething.
His name was Uchiha Ryuu — twelve years old, fresh out of the Academy, still a genin, and not yet awakened his Sharingan.
Just another unremarkable face in the Uchiha clan.
Outwardly, he looked no different — but ten minutes ago, the soul inside this body had been replaced.
Uchiha Ryuu was now a genuine otherworlder.
In his past life, he’d loved anime — and Naruto, one of the most popular shonen series of all time, was something he knew inside and out.
So even though he’d only just arrived, he’d already pinpointed exactly where he stood in the timeline.
A time of endless war.
As a lowly genin, he was nothing in a world this dangerous.
Ding!
Divine Check‑in System bound successfully!
You may check in at special locations.
The more extraordinary the place, the greater the reward.
Some locations allow repeated check‑ins; others may only be used once.
Proceed at your own discretion.
As Ryuu lifted another stone, a string of flat, mechanical voices echoed clearly in his mind.
He froze — then burst with sudden excitement.
My goddamned cheat code… finally arrived!
A valid check‑in location detected.
Would you like to check in now?
“Check in!”
What was there to hesitate about?
Ryuu’s mind rang out with a sharp, eager reply.
Ding!
Check‑in successful!
Reward granted — the Rinnegan!
The Rin… the Rinnegan?!
CRASH!
The heavy boulder in Ryuu’s hands slipped and slammed straight onto his foot — but he felt nothing.
Shock had numbed every nerve in his body.
He was completely stunned.
“The Rinnegan?!
The system is insane — first check‑in and I get the Rinnegan?!
That’s the ultimate evolution of the Sharingan!
The ultimate cheat!”
He roared inwardly, barely stopping himself from leaping for joy.
He knew exactly what the Rinnegan meant in this world — just look at Nagato Uzumaki, the powerful antagonist of the series.
Every Six Paths ability was utterly broken.
Chibaku Tensei could seal away even tailed beasts; without a god‑tier warrior like Hashirama or Madara around, it made you effectively invincible.
He’d gone from a nobody genin to a monster on the level of the Six Paths — all in a single instant.
The jump was so huge he could barely process it.
“Ryuu?
You alright?”
A voice cut through his daze.
Uchiha Shisui tilted his head, looking at him with concern.
The others had paused too, all watching him with grave expressions.
