Satoru's Nerves Were No Joke
The sun dipped below the horizon, painting Konoha in hues of crimson and gold.
Satoru walked home, muttering to himself, one hand rubbing his forehead like a man burdened with the weight of the world.
What the hell am I supposed to teach these three prodigies?
Despite being an ultimate weeb, he had zero real-life teaching experience—let alone training child assassins.
Just thinking about Kakashi, who was already called a genius before he could even walk, made Satoru break out in cold sweat.
"Damn it, I was planning to teach them tree walking and water walking… but Kakashi probably mastered that when he was three years old!"
Collapsing onto his bed, he stared at the ceiling, contemplating the cruel twist of fate that had thrown him into this absurd world.
This world was insane.
Kids barely five or six years old were wielding kunai like seasoned warriors.
By ten, they became Chunin.
By thirteen, they were leading assassination squads.
By fifteen, they were already war veterans.
And him?
At five, he was watching Doraemon.
At ten, he was grinding in online games.
At fifteen, he was binging anime and reading manga.
And at twenty-something, he was somehow isekai'd into a murder simulator and forced to train the next generation of killing machines!?
Burying his face in his pillow, he deeply regretted all his life choices.
But still—
No matter how much he panicked, he had to do something.
Emergency Purchase – A Lifeline for a Rookie Teacher
Satoru opened his system interface, checking his remaining points.
[Current Points: 270]
He frowned.
"Not much left…"
Scrolling through the shop, he searched for anything that could help him not look like a total fool.
Then—
His eyes widened.
A new category had appeared:
🔹 Collected Wisdom and Martial Philosophy of Legendary Masters.
Scanning through the list, he found:
Bruce Lee – Combat Philosophy & Tactical Thinking (100 points).Miyamoto Musashi – The Book of Five Rings, The Way of the Sword (130 points).Mas Oyama – The True Spirit of Karate (150 points).Helio Gracie – The Theory of Real Combat (120 points).
Satoru bit his lip, debating.
Then, he made his choice.
✔ Miyamoto Musashi – The Book of Five Rings.
Why Musashi?
Because Musashi wasn't just a legendary swordsman.
He was a survivor, a warrior who had endured over sixty life-or-death duels and emerged undefeated.
His strategies weren't just theoretical martial arts nonsense—they were built on real combat experience.
And in a world like Naruto, where death lurked around every corner, learning from a man who mastered battle itself was the best choice.
Praying to Musashi for Guidance
The moment he confirmed the purchase, a torrent of knowledge flooded his mind.
Battle rhythms, strategic foresight, adaptability in duels, sword techniques, and—
Most importantly—
The mental fortitude to face overwhelming odds.
Satoru's body tensed, his eyes snapping open.
Miyamoto Musashi, the unrivaled swordsman, the master of combat…
Please help me survive teaching these absurdly overpowered kids.
…No response.
Of course not.
But at the very least, he wouldn't be completely clueless anymore.
Taking a deep breath, he straightened his posture and stepped outside.
Under the fading twilight, his silhouette stood firm, like a warrior walking toward an uncertain fate.
If he didn't return tomorrow, at least they would know where to find him.
Beneath the nearest training post.
Kakashi's Perspective – A Child of Solitude
Meanwhile, in another part of Konoha, Hatake Kakashi sat alone in his quiet home.
It was a decent-sized house.
But it felt unbearably empty.
On the table was a simple meal.
No one to share it with.
Ever since his father, Hatake Sakumo – The White Fang of Konoha, had passed away…
He had eaten alone.
To the rest of the village, his father was a traitor.
Kakashi never spoke about it.
But the pain never left.
He picked up his chopsticks, silently eating his meal, staring into the steaming bowl of soup before him.
At such a young age—
He had already learned what loneliness truly was.
Obito & Gai – Opposite Spirits
Unlike Kakashi, Obito and Gai still had their families.
Before leaving home, Obito bowed to his grandmother, declaring with conviction:
"Grandma, I'm heading out to train and become Hokage!"
His grandmother simply smiled, patting his shoulder.
"Then don't let that Kakashi boy beat you."
Obito clenched his fists.
"I won't!"
He ran off, excitement burning in his chest.
"I'll surpass Kakashi for sure!"
Meanwhile, Gai was saying goodbye to his father, Might Dai—
A humble-looking man, but one overflowing with passion.
Dai grinned, slamming his fist against his chest.
"YOSH! Show your sensei the full power of youth!!!"
Gai's eyes blazed with determination.
"YES, FATHER!!!"
And with that, he sprinted off at full speed, not hesitating for even a second.
Three Kids, Three Fates – And One Extremely Nervous Teacher
By the time night fell—
The training ground at the edge of Konoha had fallen silent.
The towering trees stretched toward the moonlit sky, their gnarled roots twisting across the forest floor.
Shadows danced under the soft glow of the moon, casting an eerie, almost mystical atmosphere.
Satoru stood there, arms crossed, staring into the distance like a lost swordsman.
Then—
His three students arrived.
Obito brimming with energy, Gai radiating excitement, and Kakashi calm as ever.
Satoru took a deep breath, straightening his back, trying his best to appear like a wise master.
"Today… I will teach you your first lesson."
He met their eyes, his expression firm.
"Prepare yourselves. This will be the first step on your path to becoming true shinobi."
The three students held their breath, anticipating the unknown challenge ahead.
