Starting as a Ninja in the Naruto World

"Now..."

"Their surname is Uchiha."

"The Uchiha clan and the Senju clan have been at odds for generations."

Senju Tobirama, as if finding a kindred spirit, eagerly began to vent his grievances about the Uchiha.

"My brother defeated the Uchiha clan and convinced them to join Konoha. But even now, there are those among them who carry the same evil inclinations as their ancestor."

Tobirama failed to notice one crucial thing.

His trust in Emiya Shigen had grown significantly. He felt a natural affinity for the ancient medical ninja, enjoying the stories Shigen shared, stories that validated many of his suspicions.

And now Tobirama believed he had found a historical justification to keep a close eye on the Uchiha clan.

"My brother..."

A dark look clouded Tobirama's eyes as he spoke of someone he loathed.

"...was gravely injured by one such Uchiha."

"That man's name was Uchiha Madara."

Tobirama didn't hide his hatred and disdain as he mentioned Madara.

"My brother invited him to end the chaos of the Warring States era together. But that man betrayed him. Leaving Konoha wasn't enough—he came back and tried to destroy the village and kill my brother. He wanted to plunge the ninja world back into war!"

Luckily...

Madara Uchiha was dead.

Finally, his brother no longer had to suffer because of him.

Emiya Shigen sighed softly, his expression tinged with regret.

"It sounds like this Uchiha Madara was just as warlike as his ancestor..."

"Back then..."

"Asura wanted people to understand each other."

"But Indra sought to dominate the ninja world."

"Though they were brothers, their differing ideals drove them to conflict—a conflict that continued even after their deaths."

"Hmph!"

"This is the evil passed down through bloodlines!"

Tobirama's face twisted in anger. "Just like the cursed Sharingan they inherit, a bloodline limit steeped in emotion and destruction."

"Ah, the Sharingan..."

Emiya Shigen's gaze darkened as he recalled its history.

"I noticed long ago that Indra's Sharingan made him more extreme."

"Exactly."

Tobirama nodded firmly, feeling he had found a kindred soul. "The Sharingan evolves based on strong emotions. The more intense their feelings, the more their eyes change."

"And this means..."

"The more powerful an Uchiha becomes, the more extreme they become."

"And the more extreme they become, the more powerful they grow."

This was an unsolvable problem.

If an Uchiha's emotions weren't properly guided, they would inevitably become dangerous.

They needed to be watched.

Strictly monitored.

Closely controlled.

In Tobirama's mind, the decision was made.

He would establish a new department to manage the Uchiha clan.

A department run by the Uchiha themselves, with their residence isolated for better surveillance.

Konoha Hospital

The hospital was heavily guarded.

The battle between Hashirama and Madara at the Valley of the End had been so intense that it reshaped the land itself, leaving behind a massive canyon.

This wasn't something that could be hidden from the other ninja villages.

Spies from various nations had been infiltrating Konoha, hoping to gather information about the First Hokage's condition. His survival was directly tied to the peace of the ninja world.

"Sasuke."

Tobirama suddenly called out.

"…"

Emiya Shigen's eye twitched.

Wait… what?

Sasuke?

That's not right!

This is the early days of Konoha's founding!

Based on his knowledge from his past life, this should be shortly after the Valley of the End battle between Hashirama and Madara. How could there already be a Sasuke?

"Lord Tobirama!"

A young ninja approached swiftly.

The youth glanced at Emiya Shigen with a hint of confusion and wariness.

"Who is this?"

"This is Lord Emiya Shigen."

Tobirama spoke with great respect. "Sasuke, you can relax now. There's no need to worry about the village."

"I used a forbidden technique to resurrect Lord Emiya. He has agreed to treat my brother. You've heard of him—the greatest medical ninja in history. My brother's condition will be fine."

"The Emiya Shigen?"

The young ninja's eyes widened in astonishment.

"I grew up hearing stories about him! I never imagined I'd see him in person…"

"This is Sarutobi Sasuke," Tobirama introduced.

"The head of Konoha's Jonin Corps and leader of the Sarutobi clan. Sasuke, you must keep Lord Emiya's resurrection a secret from the village."

Tobirama wasn't a dictator.

Even though he held significant power in Konoha while Hashirama was incapacitated, he understood that other clans within the village had the right to know about the situation.

Should Hashirama's condition worsen, Konoha would be vulnerable to external threats.

Sarutobi Sasuke was key to maintaining stability within Konoha.

The Sarutobi clan, along with the Nara, Akimichi, and Yamanaka clans, had formed an alliance known as the Ino-Shika-Cho trio during the Warring States period, with the Sarutobi clan at its core.

"Let me take Lord Emiya to the patient's room," Tobirama said, patting Sasuke on the shoulder before turning to guide Shigen.

As they walked, Tobirama continued to praise Sarutobi Sasuke.

"Sasuke is a strong-willed ninja and a great leader. Even I can't compare to him in some ways."

"And his son, Hiruzen, is a talented student. He has already mastered the Sarutobi clan's summoning technique at a young age…"

Tobirama's gaze grew subtle. He clearly hoped Shigen might share some historical anecdotes about the Sarutobi clan.

"…"

Emiya Shigen glanced at Tobirama with amusement.

Does he expect me to know the Sarutobi clan's history?

Unfortunately, Shigen knew nothing about their past—only their future.

He shook his head gently.

"In my time, there was no Sarutobi clan."

"Back then…"

"There was only the Rikudou Sennin."

"Rikudou Sennin?" Tobirama's footsteps halted. He stared intently at Shigen.

"Did you… meet the legendary Sage of Six Paths?"

"Sage of Six Paths?"

Shigen chuckled softly.

"You mean to say the Senju clan doesn't know they're descended from him?"

"…"

Tobirama froze in place.

The truth struck him like a lightning bolt.

The Senju and Uzumaki clans were descendants of the Sage of Six Paths.

Emiya Shigen, however, wasn't finished.

"The Sage was a great man."

He continued, his voice wistful.

"He was the first to donate his body to medical research after death."

Of course, Shigen left out the real story.

The Sage's body hadn't exactly been willingly donated.

Shigen had accepted a mission from his system to retrieve the Sage of Six Paths' body for research.

It was thanks to that mission that Shigen had obtained true power in this world, including the Rinnegan and Wood Release.

Emiya Shigen's Stats Name: Emiya Shigen (Emiya Gen) Gender: Male Occupation: Ninja Chakra Attributes: Fire, Wind, Lightning, Earth, Water, Yin, Yang Chakra Level: Unlimited (Edo Tensei)

Emiya Shigen possessed Wood Release, Eternal Mangekyou Sharingan, Rinnegan, and Sage Mode, among many other powerful techniques.

But…

His current Edo Tensei state limited his full potential.

Emiya Shigen's gaze lingered on Tobirama.

Tobirama was a hard man to deceive.

Unfortunately for Shigen, he hadn't been resurrected by a reckless, power-hungry individual.

If only the one who resurrected me had been more foolish…

Then Shigen could've tricked them and fully resurrected himself using his Rinnegan abilities.

But it wasn't too late.

The game was just beginning.
