Within the Uchiha clan district, beneath a cherry tree in full bloom, stood a handsome young man who appeared to be around seventeen or eighteen years old.
At this moment, the young man gently rested one hand against the tree's trunk, his expression calm and contemplative.
Ding!
"Congratulations to the host. Nine-Tomoe Rinnegan progress increased by 0.3%."
A cold, mechanical voice echoed inside Uchiha Ryu's mind.
"Hm?"
Ryu looked at the cherry tree in front of him with a hint of surprise after hearing the notification.
Uchiha Ryu was a transmigrator.
He had arrived in the world of Naruto more than ten years ago.
His identity in this world was special—He was the younger cousin of Uchiha Fugaku, the current head of the Uchiha clan, and also the uncle of Uchiha Itachi and Uchiha Sasuke.
When Ryu was seven years old, a mysterious ability awakened within him—the Ultimate Sign-In System.
Once per day, he could sign in at any location and receive rewards from the system.
The more special the location, the greater the reward.
The day Ryu awakened the system happened to coincide with the Uchiha clan's ancestral memorial ceremony.
By chance, his very first sign-in took place inside the Uchiha ancestral shrine.
That single sign-in granted him an unbelievable reward—
A pair of Nine-Tomoe Rinnegan.
Even Kaguya Ōtsutsuki, the progenitor of chakra, possessed only one such eye.
Aside from her…
No one else had ever possessed it.
Yet Ryu obtained both eyes at once.
Despite gaining such power, Ryu did not become arrogant.
After carefully examining his Rinnegan, he confirmed that it had only just awakened and was far from complete.
And in Konoha, during this extremely sensitive period, that was dangerous.
The Third Great Ninja War had just ended.
All major clans were bound to be suppressed.
And the Uchiha clan…
Would undoubtedly be the first target.
Not long from now, a chain of events would unfold—
Orochimaru's defection.The Fourth Hokage taking office.The Nine-Tails Incident.And finally, the isolation and extermination of the Uchiha clan.
All of it was approaching rapidly.
Because of this, before the clan's destruction ever occurred—
Uchiha Ryu had to grow stronger.
To strengthen his Nine-Tomoe Rinnegan, he needed to continuously rely on the system's sign-ins.
Of course, the system's rewards were not limited to his eyes alone.
Over the years, he gained many additional abilities.
Thus, Ryu began signing in throughout Konoha.
Aside from a few extremely secret forbidden areas, there was hardly any notable location in the village he had not visited.
More than ten years had passed since his first sign-in.
"Open the system panel."
Ryu spoke silently in his heart.
A light-blue interface appeared before him, visible only to his eyes.

And more…
Ryu glanced over the dazzling panel, then nodded in satisfaction and closed it.
"Still… my brother."
Ryu shook his head and let out a quiet sigh.
The sharp determination in his eyes faded slightly.
Although the Third Great Ninja War was nearing its end, when it had first begun, Ryu had personally requested to go to the battlefield alongside the clan.
He had been flatly rejected by Uchiha Fugaku.
According to wartime standards, children over the age of ten were often sent into combat.
During the Warring States Period, even six-year-olds were forced onto the battlefield.
By all logic, Ryu should have participated.
Yet Fugaku refused.
He even allowed his own sons to go to war, but would not permit Ryu to step onto the battlefield.
The reason was simple.
Fugaku's parents had died during missions when he was young.
Ryu's father—who had no children of his own at the time—raised Fugaku as if he were his biological son and supported him in becoming clan head.
But fate was cruel.
Ryu's father died when Ryu was only two years old.
Soon after, Ryu's mother also passed away due to complications during childbirth.
Fugaku felt deeply indebted.
Because of this guilt, he gave Ryu everything he possibly could.
When Ryu requested to join the war, Fugaku refused without hesitation.
Instead, he appointed Ryu as Captain of the Uchiha Military Police Force, ordering him to patrol Konoha daily.
At first, Ryu wanted to argue.
But Fugaku would not yield.
After observing the state of the Uchiha Police Force, Ryu realized something troubling—
Their combat strength was dangerously insufficient.
If Sarutobi Hiruzen chose to apply pressure from above, the Uchiha would be powerless to resist.
Once the Police Force lost authority, it would only be a matter of time before their power was stripped away entirely.
That resentment would inevitably lead to conflict.
Ryu did not want bloodshed between the Uchiha and Konoha.
Not because he was afraid.
His strength already stood at the peak of the ninja world.
Even if he could not suppress all of Konoha, protecting the clan through force would not be difficult.
But the Uchiha clan was deeply rooted in the village.
Even Uchiha Madara, who once possessed godlike power, failed to convince the clan to abandon Konoha.
Ryu's influence was far less than Madara's.
If Sarutobi Hiruzen revealed true power, most of the clan would immediately turn against Ryu.
Their bond with Konoha ran too deep.
Only absolute despair would ever force them to leave.
In the end, Ryu accepted Fugaku's appointment.
"Captain Ryu!"
A voice interrupted his thoughts.
Ryu turned and saw a young man in Uchiha uniform wearing a Konoha forehead protector rushing toward him.
"What is it?" Ryu asked.
"Reporting, Captain! The war has ended! Konoha has achieved a great victory, and our forces will return soon!"
Ryu raised his eyebrows slightly.
"So it's finally over…"
As expected, the Third Great Ninja War had reached its conclusion.
"Good. Come with me. Let's welcome them back."
"Yes, Captain Ryu!"
Ryu turned and headed toward the gates of Konoha, the future already stirring beneath the calm surface.
