“Nonsense.” “This isn’t just about using surgical tools.
Medical ninjutsu requires precise chakra control and years of training.
There’s no way you could already manage it.” Aoyama Seiten knew how gifted Muzan was in medicine, but healing damaged cells with chakra wasn’t something a child should be capable of.
A surgery could last anywhere from several dozen minutes to several hours.
If Muzan collapsed midway through treating a patient, it would only cause further harm.
“Trust me.” “I can do it.” A soft green glow spread across Muzan’s hand.
Actions spoke louder than words.
He had already mastered the fundamentals of medical ninjutsu.
The blood pouring from the wound was immediately halted by his chakra.
Within moments, the damaged artery had recovered by more than seventy percent.
“What an unbelievable kid.” “Seiten really struck gold this time.” “He doesn’t seem satisfied.” “If you don’t want Muzan as your assistant, send him over to me.” “Incredible…” “Konoha’s youngest medical shinobi has finally appeared.” Under the astonished gazes of the other doctors, Seiten awkwardly climbed back to his feet.
His full attention remained fixed on the way Muzan treated the patient.
“Hands off, you old vultures.” “Muzan is my assistant!” Since Muzan was already capable of performing operations on his own, Seiten simply entrusted several patients to him.
For hours, the small figure remained tirelessly at the front lines.
Even Director Harano couldn’t hide his admiration.
“He’s a born medical shinobi.” “Konoha may one day produce a healer capable of standing beside Tsunade-sama herself.” “We absolutely must nurture his talent.” By evening, the frantic emergency operations finally came to an end.
Patients were gradually wheeled out of the operating rooms.
Only then did they learn…
The young shinobi who had saved so many lives was none other than the White Fang’s eldest son.
Dragging his exhausted body aside, Seiten quickly pulled Muzan into a quiet corner.
He kept glancing around nervously, afraid another doctor might steal his prized assistant.
“You’ve done something remarkable today.” “Konoha’s youngest medical shinobi.” “That’s a title far more dazzling than anything your little brother has earned.” Muzan wasn’t interested in titles.
What concerned him far more…
“Is war coming?” Seiten fell silent.
Without realizing it, he’d begun treating Muzan as an equal rather than a child.
After a moment, he nodded.
“Not yet.” “But the neighboring villages are watching us closely.” “No one knows when the next Shinobi World War will begin.” Ever since Tsunade-sama developed her fear of blood…
And Jiraiya-sama began wandering the world…
Konoha’s greatest military strength had diminished.
Enemy shinobi had begun appearing near the village with increasing frequency.
Large-scale war hadn’t broken out yet.
But smaller clashes and constant probing attacks never seemed to stop.
“You don’t need to worry too much.” Seiten gave Muzan’s shoulder a reassuring pat.
“There is one major advantage to being a medical shinobi.” “We’re rarely sent to the front lines.” “And even if we’re captured…” “The enemy usually won’t kill us.” Medical shinobi occupied an awkward position.
Yet their value was undeniable.
Since most lacked overwhelming combat ability, they posed little threat to enemy forces.
Their training focused almost entirely on healing and chakra control rather than offensive techniques.
“For now, just keep studying here at the hospital.” “After today, Director Harano has taken notice of you.” “He’ll even pay you a proper physician’s salary.” Money wasn’t something Muzan worried about.
His father already earned enough to support the family.
If he remembered correctly…
Hatake Sakumo’s death would occur around the time of the Third Shinobi World War.
“Please thank Director Harano for me.” “But I’m still a shinobi Academy student.” “My studies have to come first.” His reason for coming to the hospital had never been to spend all his time treating patients.
He wanted to master medical ninjutsu.
To understand how chakra affected living cells.
Besides…
He had an incredibly stubborn father waiting at home.
Unless absolutely necessary, he’d continue living a simple routine between home, school, and the hospital.
“…You’re right.” “I completely forgot.” Seiten rubbed his forehead with a twitching eye.
Looking at the tiny boy before him, he finally remembered the most important detail.
Muzan was still just a kid.
No…
The hospital had a Tokubetsu jonin (Special jonin).
Once this child graduated, he’d arrange for one of their elite shinobi to mentor him personally.
A genius like this couldn’t be allowed to fall into another faction’s hands.
Unaware of Seiten’s thoughts, Muzan finished his work at the hospital and returned to the Hatake residence after nightfall.
“Just as I expected.” Only Kakashi sat in the courtyard, eating instant ramen.
Sakumo was nowhere to be seen.
As one of Konoha’s Kage-level shinobi, it was only natural that, with war approaching, countless missions would fall to him.
“Nii-san.” “You’re back really late.” “I almost thought you’d disappeared.” Kakashi had prepared a rare steak for him.
The moment he saw Muzan’s unusually solemn expression, years of growing up together told him something was wrong.
“Did something happen?” “A group of injured shinobi arrived at the hospital.” “They were wounded during clashes with another village.” Beneath his crimson eyes, Muzan looked quietly toward the full moon hanging overhead before speaking.
“War is coming.” “The village won’t remain safe for much longer.” “Be careful.” Thinking back to Sakumo’s hurried departure that morning…
His father had privately warned him that he wouldn’t be returning to the village for some time.
The two brothers would have to look after themselves.
“So Father really left on a mission.” “No wonder he didn’t even have time to say goodbye properly.” “Too bad, Nii-san.” “You’re a little late saying that.” “Take a look at this.” Kakashi proudly held up an official notice.
It was an early graduation approval from the shinobi Academy.
The Hokage’s signature had already been stamped onto it.
As long as he passed tomorrow’s examination…
He would officially become a Genin.
For the first time in a long while, Muzan’s normally calm expression cracked.
His crimson eyes narrowed into a frightening shape.
He suddenly felt an overwhelming urge to beat some sense into his little brother.
“You brat.” “You can’t even beat me.” “And you think you’re ready to become a Genin?” “Go train some more!” Kakashi pointed proudly at the Hokage’s signature.
“Hmph!” “You can’t stop me.” “The Hokage-sama personally approved it.” “Even Father can’t cancel this examination.” After being repeatedly defeated by Muzan…
Especially after hearing that his brother had become Konoha’s youngest medical shinobi…
Kakashi had made up his mind.
He would prove himself.
He would graduate early and become a true Genin.
Hatake Kakashi would never lose to anyone.
Not even…
His own older brother.
