If any of the other medical staff saw Yakushi Nono speaking to Kiyoshi in such a gentle, almost coaxing tone,
They would definitely be stunned.
On the surface, she appeared kind and easygoing—
But when it came to her work,
She was ruthless and precise,
No different from the cold-blooded ninjas of the Anbu.
Soon after,
Yakushi Nono led Kiyoshi to another room
To conduct a series of tests.
Kiyoshi readily agreed.
After going through multiple examinations,
She finally confirmed—
That he possessed the Yang attribute.
"From now on, you'll study medical ninjutsu under me."
Yakushi Nono said.
Since she had already made that promise to him,
She naturally intended to keep it.
Besides…
Before leaving Konoha one day,
Taking in a pure, untainted child as a student
Wasn't such a bad thing.
In her eyes,
Every child was like a blank sheet of paper—
Untouched by the filth of the world.
Having spent years working for Root,
Carrying out countless missions,
Yakushi Nono had seen far too much darkness.
She also knew very well
About the suppression and marginalization
Of the Uchiha clan within Konoha.
Especially her superior—
The leader of Root, Shimura Danzo.
His dislike for the Uchiha
Had long crossed into outright prejudice.
He constantly muttered criticisms
Once spoken by his teacher, Tobirama Senju.
Because of that—
Many children like Kiyoshi,
Simply for bearing the Uchiha name,
Seemed to carry an original sin.
But these were things
Yakushi Nono couldn't change.
Nor interfere with.
The only thing she could do
Was eventually leave Konoha
And open an orphanage somewhere far away,
Living out the rest of her life there.
"Alright, Nono-sensei."
Kiyoshi immediately called her "teacher."
Then looked at her eagerly.
At that moment,
Yakushi Nono was wearing a white coat,
Her figure subtly emphasized beneath it.
Compared to the black nun outfit from before,
She now looked more like
A compassionate healer saving lives.
Yakushi Nono shook her head with a soft laugh.
"Don't worry. I'll teach you medical ninjutsu. Let's start with a D-rank technique."
She brought Kiyoshi to her office
And began searching through some materials.
Soon,
She took out a pale white scroll
And handed it to him.
"This is the Healing Technique. It can restore minor external injuries."
Kiyoshi opened it,
Noticing the dense amount of text inside.
"When using medical ninjutsu, precise chakra control is essential. You must also be able to maintain chakra steadily over long periods. It's a skill that requires real dedication."
"Yes, Nono-sensei. I'll study hard and repay you in the future."
His words made her smile.
A newly graduated genin
Talking about repaying her—
It felt… oddly sincere.
Perhaps it was because he came from the Land of Lightning,
But there was a kind of simplicity and purity in him.
Of course,
If an adult had said the same thing,
She would've found it insincere.
"It's enough that you have the intention."
After that,
She picked up a transparent glass,
Pouring coffee and milk together,
Gently stirring them
Until they formed a muddy mixture.
"If you want to become a medical ninja, this is your first lesson."
She said calmly.
"Use chakra to separate these two liquids."
Children's interest
Came quickly—
And faded just as fast.
She wanted to test
Kiyoshi's interest in medical ninjutsu,
As well as his talent.
Hearing this,
Kiyoshi placed both hands on the glass,
Circulating chakra
Through the meridian system in his arms,
Trying to pass it through the glass
And control the liquid inside.
Watching his focused expression,
Yakushi Nono added:
"Although both are liquids, coffee and milk have different densities. That's why they can be separated. This is the foundation of medical ninjutsu—and the core principle behind the Poison Extraction Technique. If you can't master this, becoming a medical ninja won't be easy."
As she explained,
She carefully observed his reactions.
She was already prepared
To guide him for a long time.
After all,
This exercise was not simple.
Even genin
Usually needed several hours
Just to grasp the basics.
For those with poor talent,
It could take days—
Or even months.
The Poison Extraction Technique
Was also used to remove toxins from the body.
If poisoned during a mission,
Or if a teammate was bitten by a venomous creature,
This skill could save lives.
Without mastering it,
Becoming a medical ninja
Would be extremely difficult.
Possessing the Yang attribute
Only meant that learning medical ninjutsu
Would be easier compared to others.
But ultimately—
Success depended on
One's ability to precisely control chakra.
That was why medical ninjutsu
Was far more difficult than other types,
And why medical ninjas
Were so rare.
Kiyoshi listened carefully,
Fully focused on separating the mixture.
With the [Genius Scholar (Green)] trait,
His learning speed
Had increased significantly.
Combined with his solid foundation,
His chakra control
Was already exceptional.
After only a few dozen seconds—
Before Yakushi Nono had even finished explaining—
Kiyoshi's hands trembled slightly.
But inside the glass,
Something began to change.
The muddy mixture
Started to separate.
The coffee gradually rose to the top,
While the milk settled at the bottom.
The two distinct colors
Became clearly divided.
"…How is this possible?"
Yakushi Nono blinked,
Almost doubting her own eyes.
She unconsciously leaned forward,
Her white coat tightening slightly.
She had personally guided many students through this exercise.
Even those with talent
Usually failed on their first attempt—
Or at best created a vague separation.
Yet this boy,
Who had just become a genin—
Had nearly perfected it
In mere seconds.
Her lips moved slightly,
As if wanting to say something,
But no words came out.
Countless thoughts flashed through her mind.
For a brief moment,
She even wondered if he had secretly practiced something similar before.
But judging from his focused yet youthful expression,
It was clearly his first time.
And deception—
Would never escape her notice.
Kiyoshi looked up at her and said:
"Nono-sensei, I did it!"
"…Mm."
She nodded slowly.
A new thought
Formed in her mind—
Perhaps…
She should truly nurture him.
Before leaving Konoha,
Maybe she could leave something behind.
After all,
Every medical ninja
Was an extremely rare asset.
Training even one
Was no easy task.
Otherwise,
Every three-man squad
Would already include a medical ninja.
