Naruto: The Legendary Medic From Ancient Times

(See if you like it)

Synopsis:

Konoha Year 5.

The battle at the Valley of the End between Hashirama Senju and Madara Uchiha had concluded.

To save his elder brother from suffering long-term effects from his injuries, Tobirama Senju resurrected an ancient-era medical ninja, hoping this individual could ensure that his brother's wounds wouldn’t shorten his lifespan.

This medical ninja’s name was Shirou Emiya.

Chapter 1: Shirou Emiya

Konohagakure.

In the dimly lit underground chamber, the air was heavy and still.

At the center of the room rested a sealed crystal coffin, an artifact of intricate design. Beautiful engravings adorned its surface, but its contents were chilling—inside lay half a corpse.

Through the translucent crystal, one could see the internal organs of the body clearly, as though it were a medical specimen. The eerie sight rendered the chamber especially unsettling.

The silver-haired man standing there seemed unbothered by the grim atmosphere. His cold, determined crimson eyes fixated on the coffin before him.

“Tobirama-sama.”

An ANBU ninja wearing a mask entered the chamber, dragging a bound prisoner behind him. In a hushed tone, he reported, “In the past few days, a number of enemy ninjas from foreign nations have infiltrated the village to gather intelligence. After a thorough sweep of the cells, this Sunagakure ninja, who snuck into the village last night, was identified as the one with the strongest chakra in the entire prison...”

“What about my broth—”

Halfway through speaking, Tobirama caught himself. Changing his phrasing, he asked, “What’s the status of the Hokage?”

“He’s still undergoing treatment,” the ANBU replied with concern. “We’ve never seen the Hokage suffer injuries this severe. Lady Mito says it might even shorten his lifespan…”

Tobirama’s expression darkened instantly. After a brief silence, he asked, “And the Uchiha clan? Any unusual movements?”

“None so far.”

The ANBU shook his head lightly. “Ever since the news broke yesterday that Uchiha Madara was killed by the Hokage, the Uchiha clan seems more fearful than anything else. No other anomalies have been detected...”

“Continue monitoring them closely,” Tobirama instructed. He then shifted his gaze to the bound Sunagakure ninja and ordered coldly, “Have the other ANBU squads tighten patrols around the village. Assign one squad to guard this forbidden chamber. No one is to approach without permission.”

“Yes, Tobirama-sama!”

The ANBU ninja promptly exited, leaving behind the captive Sunagakure ninja, who looked up at Tobirama with muffled groans, desperation evident in his eyes.

“I know what you want to say,” Tobirama remarked dismissively, barely glancing at the man. “But I have no interest in hearing your excuses.”

His tone turned icy. “You infiltrated the village to gather information on my brother, or perhaps to confirm that he and that bastard Madara perished together... Dream on.”

Tobirama’s gaze returned to the crystal coffin before him. His voice, steady yet resolute, carried an air of defiance.

“This crystal coffin stands as the proof to the origins of medical ninjutsu.”

“Shirou Emiya.”

“You must have heard of that name.”

The Sunagakure ninja’s eyes widened in astonishment as he looked at the coffin.

Shirou Emiya.

That name was legendary.

Everyone in the ninja world knew of this saint from a millennium ago—a man who pioneered the concept of medical ninjutsu and established the system of medical ninja.

Legends spoke of his compassion: healing anyone in need, regardless of their status; curing the most severe ailments; saving more lives than the population of a small nation.

Even his death was an act of selflessness.

In his final moments, Shirou Emiya sought to eliminate prejudice against surgical anatomy and healing practices. To ensure the continuation of medical ninjutsu, he ordered his body to be preserved in two crystal coffins, leaving them as gifts to the ninja world.

For a thousand years, through the chaos of the Warring States Period, these coffins remained untouched—revered and respected even in times of war.

Staring at the half-corpse within the coffin, the Sunagakure ninja felt a mix of awe and unease.

What could a long-dead healer have to do with the present? No matter how skilled Shirou Emiya had been, he couldn’t possibly rise from the dead to treat the First Hokage, right? Was there some secret medical technique hidden within the coffin?

“Our Senju clan has always been known for our chakra control, making us naturally suited for medical ninjutsu,” Tobirama began, his voice low.

“It’s said that Shirou Emiya personally entrusted this crystal coffin to our ancestor…”

“Even though most of us focus on combat rather than healing, this coffin has always been a symbol of pride for our clan.”

Tobirama’s gaze softened as his fingers traced the intricate carvings on the coffin. His voice dropped further, carrying a note of sorrow.

“I never thought I’d one day have to destroy it with my own hands…”

The Sunagakure ninja’s face contorted in horror.

“But for my brother…”

“Anything can be sacrificed!”

With that declaration, chakra glowed faintly in Tobirama’s palm as he slammed his hand down on the coffin.

CRACK!

The crystal shattered.

The half-corpse within tumbled to the ground.

The bound Sunagakure ninja, now frozen in terror, watched the scene unfold.

“Only my brother can guarantee the peace of Konohagakure…”

Tobirama began forming hand seals with remarkable speed, his voice calm yet resolute.

“Even if there’s only a one-in-a-million chance, even if it means desecrating the soul of the dead…”

As his hand struck the ground, his voice turned cold as ice.

“Edo Tensei no Jutsu!”

Dark seals spread beneath his hand, snaking across the floor. The patterns formed two separate barriers—one surrounding the half-corpse, the other encasing the Sunagakure ninja.

Under the horrified gaze of the prisoner, the ash and dust from Shirou Emiya’s body began to rise, attaching themselves to the living ninja’s form.

A suffocating despair engulfed the prisoner as the dust covered his eyes and body until his form was entirely consumed.

Tobirama’s eyes locked onto the emerging figure. The jutsu had succeeded.

The Edo Tensei’s host began to transform, taking on the appearance of the legendary healer.

Finally, the resurrection was complete.

Standing before Tobirama was a young man with an air of compassion belying his age—perfectly matching the world’s image of Shirou Emiya.

The revived soul slowly opened his eyes, glancing at his form in confusion, as though uncertain why he was alive or why he was here.

Tobirama exhaled in relief. The technique had worked, and the resurrected Shirou Emiya retained his mind.

“Shirou Emiya-dono,” Tobirama addressed him formally, his voice heavy with respect. “I am Senju Tobirama, the one who summoned you back to this world…”

“My apologies for disturbing your peace.”

“But we require your help to save someone vital to the ninja world. I had no choice but to violate your soul. I hope you can forgive this offense.”

“You’re from the Senju clan?” Shirou's demeanor eased.

“If it’s to save lives, such actions can be forgiven.”

His calm response matched his saintly reputation. Without hesitation, he shifted his focus to the matter at hand.

“Where is the patient?”

Tobirama was momentarily stunned but relieved. This legendary figure seemed just as altruistic as the stories described.

However, Tobirama failed to notice the subtle change in Shirou's demeanor. His eyes, tinged with a deadened Edo Tensei glow, betrayed an undercurrent of something far darker.

[Reconnecting to Ninja System...]

[Welcome back, Ninja Shirou Emiya.]

[Unfinished missions detected. Unable to exit this world.]

[Pending SSSSS-Rank Missions (2/3):]

• Defeat the ultimate antagonist of this world—Ōtsutsuki Kaguya.

• Defeat the world’s final protagonists—Naruto Uzumaki (Sage of Six Paths Mode) and Sasuke Uchiha (Rinnegan).

The system was still intact.

And his power... remained.

A faint red gleam flickered in Shirou's eyes as he smirked inwardly.

His centuries-long plan had finally reached this era.

...

Chapter 2: The Origins of the Senju and Uzumaki Clans

The Hidden Leaf Village was far from prosperous.

At least, in this era, the village hadn't yet achieved true prosperity.

Many of its buildings had a rough, makeshift appearance, likely due to the villagers being too preoccupied with daily affairs to focus on elaborate construction.

Shirou didn’t mind the village’s simplicity; instead, he curiously observed the surroundings, intrigued by the sights he encountered after his resurrection.

“This is the village we live in,” said Tobirama Senju.

While directing the Anbu to maintain vigilance, Tobirama began sharing the stories of this era with Shirou. “It has been over a thousand years since your time…”

“A thousand years, huh?”

Shirou sighed softly, a hint of melancholy in his tone. “No wonder the architecture looks so different from what I remember…”

After remarking on the village’s structures, Shirou suddenly seemed to realize something, and a flicker of excitement crossed his face. “Speaking of which, if a millennium has passed, the medical ninjutsu of today must be incredibly advanced. Back in my time, we didn’t even have techniques to resurrect the dead! The brilliance of future generations is truly remarkable.”

“…”

Tobirama’s expression grew complicated.

“It’s… a bit embarrassing,” he admitted with a long sigh, hoping Shirou wouldn’t be too disappointed by the current state of medical ninjutsu. “The forbidden jutsu that revived you wasn’t created for healing—it was developed for combat purposes. In fact, it was a stroke of luck that I managed to restore your consciousness at all. Medical techniques today are still largely the same as they were during the era you established…”

“Is that so?”

Shirou's face visibly darkened, as though his ideals had been shattered. “So humanity has continued to use chakra as a tool of war after all?”

For a medical ninja, war was undoubtedly the most detestable thing.

The Senju Clan had preserved Shirou's crystal coffin for generations, and Tobirama had grown up hearing countless tales about this legendary figure. He could guess at Shirou’s aspirations but felt compelled to help this revered elder face reality.

“All of it was for survival.”

“In the harsh Warring States Period, we had no choice but to use chakra to enhance our combat capabilities in order to survive.”

Tobirama didn’t shy away from the truth. He recounted the chaotic Warring States era and took the opportunity to praise his older brother, hoping Shirou could grasp the significance of his brother’s role in this time period.

“Fortunately… the wars eventually came to an end.”

“My elder brother, Hashirama Senju, used his unparalleled strength to bring the Warring States chaos to a close and established a system of peace through nations and shinobi villages.”

“We invited other clans to join us in founding the Hidden Leaf Village, encouraging former enemies to set aside their hatred and become comrades who rely on one another.”

“In the future…”

Tobirama paused briefly, using the moment to paint an optimistic picture for the legendary medical ninja. “As long as my brother’s injuries heal without shortening his life, his influence will undoubtedly ensure lasting peace in the shinobi world. And with peace, medical ninjutsu will surely see even greater advancements.”

“…”

Shirou's expression turned subtly ambiguous.

However, Shirou chose not to directly puncture the hopeful narrative Tobirama had crafted. With a soft sigh, he replied, “Don’t worry. I never fail my patients—especially those who bear the name Senju…”

“…”

Tobirama showed no signs of awkwardness.

As someone who prioritized results over appearances, the assistant to the Hokage had no qualms about sacrificing his own dignity to achieve his goals.

However…

Was there a story behind this revered figure from a millennium ago, who had been deified by history?

Tobirama recalled Shirou's relaxed demeanor when mentioning the Senju Clan. Unable to suppress his curiosity, he probed further. “It seems, Lord Emiya, that you share some connection with our Senju Clan. After all, our children have grown up hearing stories about you.”

“There’s a bit of a connection,” Shirou admitted.

“If your clan is descended from Asura, then…”

“Asura?”

“Yes.”

Shirou walked alongside Tobirama, nonchalantly recounting the history he had witnessed. “I once had a friend named Asura. Since he couldn’t use his father’s surname, I helped him come up with two surnames for his descendants to use…”

“One was Senju.”

“The other was Uzumaki.”

Shirou’s gaze rested on Tobirama as he let out a wistful sigh. “It seems Asura’s descendants ultimately chose the name Senju…”

“…”

Tobirama’s pupils dilated in shock. He hadn’t anticipated learning the origin of his clan’s name in this way.

It wasn’t a lie.

Both surnames—Senju and Uzumaki—existed and had persisted through time.

The clans that arose from these names shared a common ancestor and had survived to the present day, with the Senju and Uzumaki Clans maintaining distant familial ties.

“In truth…”

“Both names were used.”

“The Uzumaki Clan, which bears the other name, is our distant relative,” Tobirama said, taking a deep breath. “It’s astonishing to think that the surnames of the Senju and Uzumaki Clans both originated from you, Lord Emiya…”

He could already imagine his brother lecturing him once he awoke.

Using the forbidden Edo Tensei to resurrect a respected historical figure was one thing, but discovering this elder’s close ties to their ancestors added another layer of complexity.

“Time flies, and the world changes,” Shirou said, his tone heavy with nostalgia. It was clear he missed his old friend. “I never imagined that after so much time, Asura’s descendants would still be here…”

“…”

Tobirama remained silent.

But inwardly, he could tell that Shirou and their ancestor, Asura, had been close friends.

This was good news.

At the very least, Shirou seemed to be friendly.

Even so, Tobirama couldn’t completely trust a power he couldn’t control. His cautious nature wouldn’t allow it—just as he remained wary of the Uchiha Clan.

Although the Uchiha were part of the Hidden Leaf Village, Tobirama couldn’t fully trust a clan with such unpredictable abilities…

Especially after the recent attack.

Madara Uchiha, the former leader of the clan who had left the village years ago, had returned to unleash the Nine-Tails on the Hidden Leaf. The attack left Hashirama gravely injured.

This incident prompted Tobirama to tighten the village’s surveillance on the Uchiha Clan.

Even though Madara had been defeated and killed, Tobirama couldn’t dismiss the possibility that another threat as dangerous as Madara might arise from the Uchiha in the future.

After all…

While Hashirama’s existence was an exception for the Senju, Madara was no anomaly for the Uchiha.

Their Kekkei Genkai, the Sharingan, could awaken and evolve unpredictably, potentially giving rise to another Madara-like figure.

It was a risk Tobirama couldn’t ignore.

“I wonder…”

“If Indra’s descendants still exist…”

At that moment, Shirou mentioned a name unfamiliar to Tobirama. To clarify, he began explaining Indra’s story.

“Indra and Asura were brothers.”

“Back then, Indra and I had differing ideals.”

“Asura and I believed chakra should be used to bring understanding and healing to the world. Indra, on the other hand, saw chakra as a means to dominate.”

“In the end…”

“We went our separate ways.”

“I don’t know what surname Indra’s descendants adopted,” Shirou admitted, before detailing some characteristics of Indra’s bloodline.

“However, they likely inherited a unique and powerful Kekkei Genkai. This Kekkei Genkai manifests as distinctive chakra within their eyes, and as it evolves, it grants them access to extraordinary and mysterious ocular techniques…”

“That would be the Sharingan,” Tobirama interjected.

His eyes darkened as he connected the dots. To think that Indra and Asura were brothers—and that the Uchiha Clan shared roots with the Senju Clan’s ancestor…

It confirmed Tobirama’s suspicions: the Uchiha were inherently dangerous.

Even a virtuous figure like Shirou, known for his noble ideals, had distanced himself from Indra’s descendants.

As far as Tobirama was concerned, this revelation only reinforced his belief that the Uchiha’s power was inherently malevolent.

...

Chapter 3: The Power of Shirou Emiya

"Now..."

"Their surname is Uchiha."

"The Uchiha Clan and the Senju Clan have been bitter enemies for generations."

Tobirama Senju, as if finding a kindred spirit, began voicing his grievances about the Uchiha. "My elder brother defeated the Uchiha and persuaded them to join Konoha. But even within their clan, there are still those as wicked as their ancestors..."

However, Tobirama overlooked a key issue.

This assistant to the Hokage of Konoha was gradually gaining trust in Shirou due to the stories the latter shared, which were exactly the type Tobirama enjoyed hearing.

That said, Tobirama couldn't have suspected someone claiming to be from over a thousand years ago. Instead, he extracted from Shirou's words a strong justification for monitoring the Uchiha Clan!

"My brother..."

Tobirama's expression darkened as he mentioned a man he deeply despised: "He was gravely wounded by an inherently evil Uchiha..."

"That man... his name was Madara Uchiha."

When Tobirama uttered the name, his voice brimmed with undisguised hatred and contempt. "Back then, my brother invited him to end the Warring States era together. But that man betrayed my brother's trust. Leaving Konoha was bad enough, but when he returned, he sought to destroy the village, kill my brother, and plunge the Shinobi World back into the fires of war from the Warring States era."

Fortunately, Madara was finally dead. My brother was no longer bound by him.

Shirou sighed as if lamenting something tragic. "It sounds like this Uchiha Madara was as battle-hungry as his ancestor..."

"Long ago..."

"Asura desired understanding among people."

"But Indra sought to dominate the Shinobi World."

"Although they were brothers by blood, they began a feud over their conflicting ideals, which persisted even beyond their deaths..."

"Hmph!"

"This is what we call inherited wickedness!"

Tobirama's face twisted with disdain as he sharply criticized the Uchiha Clan. "Just like the cursed Kekkei Genkai they inherited—the Sharingan..."

"The power of the Sharingan, indeed..."

Shirou spoke about the Sharingan's history: "Back then, I observed how the Sharingan’s power gradually drove Indra to extremism..."

"Precisely."

"I have also studied the Sharingan extensively."

"The evolution of this Kekkei Genkai is undeniably influenced by emotion."

Tobirama earnestly shared his insights, as if finding a confidant. "The Sharingan’s progression is fueled by the chakra born from intense emotions..."

"This means..."

"The stronger an Uchiha becomes, the more prone they are to extremism."

"And the more extreme they are, the stronger they often become..."

This was an unsolvable dilemma.

If the emotions of an Uchiha couldn’t be properly guided and their life remained turbulent, they would eventually become extremely dangerous.

They must be monitored!

Strictly monitored!

Monitored with utmost rigor!

Tobirama silently resolved to implement his plan. Since Konoha lacked the manpower to monitor every single Uchiha, they would need to be centralized.

For now, the Uchiha were still allies.

He needed to establish a new department for them.

This department would be managed by the Uchiha themselves, and their residences would be consolidated. Meanwhile, the Anbu would covertly dispatch personnel to monitor them.

Konoha Hospital

The hospital was heavily guarded.

The recent battle between the First Hokage, Hashirama Senju, and Uchiha Madara had been so intense that its aftershocks reshaped the geography, creating a valley where they fought.

Such a battle couldn’t escape the notice of other hidden villages.

Shinobi from other nations infiltrated Konoha to gather information about the First Hokage because his safety was crucial to the peace of the Shinobi World. Konoha had no choice but to tightly seal all intelligence regarding Hashirama.

"Sarutobi."

Tobirama suddenly called out loudly.

"..."

Shirou’s eyelid twitched.

Wait a minute...

Something was off.

Why was Sarutobi suddenly mentioned?

Wasn’t this supposed to be shortly after Konoha’s founding?

According to his memories from his past life, this timeline should be right after the Battle of the Valley of the End. Why was there already a Sarutobi here?

"Lord Tobirama!"

A young ninja strode forward briskly.

The young man glanced at Shirou beside Tobirama, his eyes filled with a hint of confusion and a trace of wariness.

"Lord Tobirama, this is..."

"This is Lord Shirou Emiya."

Tobirama, who clearly trusted this young ninja greatly, spoke in a serious tone: "Sarutobi, you can now rest easy. There’s no need to worry about the village’s situation anymore."

"I used a forbidden technique to resurrect Lord Emiya and requested his assistance in healing my brother’s injuries. You’ve probably heard of his name. My brother’s injuries are no longer an issue."

"Is this the legendary medical ninja, Lord Emiya?"

The young ninja’s face lit up with astonishment as he looked at Emiya Shirou in disbelief. "I grew up hearing tales of Lord Emiya. I never imagined I’d get to see him in person one day..."

"This is Sasuke Sarutobi, the captain of Konoha’s Jonin squad."

Tobirama introduced the young man to Emiya Shirou and then instructed Sasuke: "Sarutobi, keep everything about Lord Emiya strictly confidential within the village..."

Although Tobirama held considerable authority as the Hokage’s assistant, he didn’t govern with absolute dictatorship.

With Hashirama injured, the other clans in the village were restless, and Tobirama believed they had a right to know about the situation.

If the worst happened...

Konoha could become vulnerable to hostile actions from other villages.

At this critical juncture, Tobirama needed to unite the clans to prevent Konoha, still in its infancy, from collapsing due to his brother’s condition.

...

Chapter 4: Bullying Me Because I’m an Old Relic?

In front of the ward at Konoha Hospital.

Senju Tobirama sincerely hoped that Shirou would keep the secrets of the ancient era to himself, especially not revealing them to his older brother, Senju Hashirama.

He knew exactly what kind of person his older brother was.

If Hashirama found out that the Senju and Uchiha ancestors were brothers, both descendants of the Sage of Six Paths, he would treat the Uchiha clan with even more kindness and tolerance.

This would interfere with Tobirama’s future plans to suppress the Uchiha clan.

In fact, Tobirama would have preferred it if Shirou only disclosed the malevolent nature of the Uchiha ancestor, Indra, to the public. That would make it easier to justify his actions against the Uchiha clan.

However, Tobirama knew that Shirou was a principled man. Surely, he’d realize that such selective disclosure was just a ploy to marginalize the Uchiha clan, and he probably wouldn’t agree to it.

So…

Tobirama chose his words with extreme caution.

"Lord Emiya," he began.

"Konoha’s current situation is unstable," Tobirama said gravely, without hesitation, weaving an elaborate lie. "If these ancient secrets were to be exposed, they’d undoubtedly provoke much debate..."

"Even though Madara tried to destroy Konoha, we still view the Uchiha who joined Konoha as comrades..."

"If people in the village learned the story of Indra, they’d inevitably begin to suspect the Uchiha as inherently evil and alienate them further."

"..."

Shirou’s expression became peculiar.

Really?

Do you think I’m an old relic who’s easy to fool?

I’m dead, sure, but that doesn’t make me ancient.

The Second Hokage of Konoha, Tobirama, worrying about people ostracizing the Uchiha? It sounded like a bad joke.

Besides...

Weren’t you the one who started the trend of alienating the Uchiha in the first place?

However…

Tobirama was remarkably skilled at presenting himself persuasively.

"My brother has always been overly kind to the Uchiha, trying to integrate them into Konoha. If he learns that the ancestors of the Senju and Uchiha were brothers—and knowing that he already feels guilty for having to kill his former friend, Madara, to protect the village—he would likely become even more partial to the Uchiha clan."

"In such a scenario..."

"The other clans in the village might perceive this as unfair."

"If news spreads that our ancestors, Asura and Indra, were brothers, people will inevitably question my brother’s impartiality."

"My brother is the First Hokage of Konoha."

"Currently, the relationships among the various clans in Konoha are fragile. Any doubts about the Hokage’s fairness could cause the hard-earned peace to crumble."

Tobirama’s reasoning circled back to his initial plea: "Lord Emiya, for the sake of peace in Konoha and the shinobi world, I must implore you to keep these ancient secrets buried."

"..."

Shirou couldn’t find a valid reason to refuse.

After all, Tobirama’s words were tactful, laced with moral undertones, almost as if questioning Shirou outright: As a virtuous person from ancient times, would you really want to see the shinobi world descend into chaos again?

In these times...

Being a good person was just too hard.

If you wanted to be virtuous, you had to be ready to be morally cornered.

Luckily, Shirou was better at cornering others with morality.

"I can only try not to say anything inappropriate," Shirou said, shaking his head and hesitantly explaining. "In our era, people often communicated their thoughts openly using chakra during spiritual training. Everyone was straightforward, rarely hiding their true thoughts or lying to their comrades."

"My apologies."

"I can only do my best," he added with a hint of regret, hoping Tobirama could understand his upright nature. "I’m not very skilled at concealing my true intentions."

"The one who should apologize is me," Tobirama sighed deeply, his mind briefly drifting to the ancient stories. There was a wistful longing in his tone as he spoke.

"I’ve heard legends about the Sage of Six Paths. It’s said that in his era, when he founded ninshū, people respected and understood each other..."

"I never imagined..."

"That those legends were actually true..."

"Well, not entirely," Shirou said, somewhat embarrassed, rubbing his brow as if casually explaining. "For instance, no one in ninshū could understand the ideas of Indra, the Uchiha ancestor. Eventually, he left ninshū and tried to destroy the village using the power of the Sharingan. Ultimately, Asura united everyone’s chakra to defeat him."

"What!"

Tobirama was startled by the all-too-familiar narrative and instinctively disparaged Indra. "That inherently evil Uchiha ancestor!"

The behavior described was identical to Madara’s.

Madara had left Konoha, attempted to destroy it, and was ultimately killed by Hashirama, foiling his malicious plans.

Madara and his ancestor were both despicable!

"Speaking of which..."

Shirou changed the subject, casually praising Tobirama, "You and your brother seem to have a great relationship. It’s rare to see such harmony between siblings."

"That’s only natural," Tobirama said, his heart tinged with nostalgia as he recalled his brother’s protective care during their childhood. "My brother has always looked out for me..."

Shirou...

He really is a good person.

At least, Tobirama thought so.

Based on what Shirou said, the ancient ninjas seemed to be good people, and their era must have been a true utopia.

Well...

Except for that inherently evil Uchiha ancestor.

"Let’s go in."

Tobirama pushed open the ward’s door, his attitude toward Shirou becoming more respectful. "There’s nothing we can do for my brother’s injuries. We can only rely on you, Lord Emiya."

"There’s no need for such formalities."

Shirou waved his hand and turned to enter the ward, his demeanor suddenly serious. "Rest assured, as a medical ninja, I won’t fail my patient."

The ward carried a faint scent of flowers.

Shirou’s gaze fell on the figure lying in the hospital bed.

The man had long black hair, his body tightly wrapped in bandages. Though motionless, his breathing was steady.

The First Hokage, Hashirama Senju.

Undoubtedly the strongest ninja of this era.

"My brother has never been this weak," Tobirama said, his face grim. "The battle with Uchiha Madara a few days ago nearly drained all his chakra."

"Let me take a look..."

Shirou placed his fingers on the patient’s wrist.

"A Wood Release user?" Shirou seemed intrigued, lost in thought.

"Theoretically, Wood Release originates from the power of the God Tree. Back in the day, Asura only awakened it because the Sage of Six Paths granted him chakra. It shouldn’t be something inheritable by later generations."

"My brother awakened Wood Release as an adult," Tobirama immediately noted the revelation and reminded Shirou of the matter at hand. "Lord Emiya, how is his condition?"

"Don’t worry," Shirou reassured Tobirama. "The patient has strong regenerative abilities. The only issue is that his chakra depletion has slowed his recovery. Once his chakra is restored, he’ll be fine."

"..."

Tobirama thought this was stating the obvious—he’d already deduced as much.

"However..."

Shirou paused, raising a more concerning issue. "The patient’s excessive use of regenerative abilities has caused accelerated cellular division and regeneration, which has damaged his lifespan. On top of that, he’s overused his life energy to enhance his Wood Release. That’s the real issue here."

"Is it manageable?"

Tobirama’s tone was unexpectedly calm, even relaxed. "In other words, can you fix it, Lord Emiya?"

"In ancient times, this would’ve been a minor issue," Emiya Shirou said, his eyes narrowing slightly with regret. "With Yang Release, I could easily heal him. However, in my current state—practically no different from a dead man—I can’t use Yang Release."

If only...

He could achieve a perfect resurrection.
