Before beginning the next serious story she had planned, Tsukiko decided to write something more relaxed and fun. This story would not be tied to any heavy plot or complicated structure. It would simply be a lighthearted adventure in the ninja world, free and unpredictable.
And yes… this story would also contain a Yuri element.
That was something Tsukiko had never hidden from herself.
---
Uchiha Tsukiko was not originally from this world.
In her previous life, she had been an ordinary woman living in a completely different universe. Her life had been simple. She worked, ate, slept, and occasionally enjoyed reading novels and watching videos online.
Well… there was one small detail.
She preferred girls.
Other than that, she had lived a fairly normal life.
That normal life ended rather suddenly.
One day, while working near heavy mining equipment, a terrible accident occurred. Electricity surged through the machinery, and before she even understood what was happening, her vision turned white.
Then everything went dark.
When she opened her eyes again, she was no longer in the same world.
She had been reborn.
---
At first, Tsukiko didn't even realize what had happened.
Her memories from her previous life remained, but the body she now controlled belonged to a small child.
An orphan.
The world she found herself in was harsh. Wars between villages had left many children without families, and she was one of them.
For several years, she lived quietly in the Hidden Leaf Village, trying to understand where she was.
Her knowledge about the world came from scattered memories.
Naruto.
She had only seen short clips and videos of the series before in her previous life, so her understanding of the story was extremely incomplete.
Because of this, she couldn't immediately recognize the situation she was in.
Everything remained confusing.
Until one day.
When she was about five years old, her adoptive mother in this world, Uchiha Kaede, brought her to meet the family next door.
A small boy was sitting in the yard.
He looked around three or four years old, with dark hair and calm eyes.
When Kaede gently introduced them, the boy bowed politely.
"My name is Itachi."
The moment Tsukiko heard that name, something inside her froze.
Itachi.
Uchiha Itachi.
That single name shattered her confusion.
Suddenly, the world made sense.
She had been reborn into the Naruto world.
And worse…
She had been reborn into the Uchiha Clan.
---
At first glance, that sounded like incredible luck.
The Uchiha were famous for their powerful Sharingan and incredible combat abilities.
But Tsukiko knew the truth.
If things followed the original story, then one night in the future, Uchiha Itachi would slaughter the entire clan.
A tragedy known as the Uchiha Massacre.
And she…
would simply be one more corpse.
Realizing this made Tsukiko extremely depressed.
She wasn't Naruto.
She wasn't Sasuke.
She wasn't some legendary ninja.
She was just a random background character.
A passerby in someone else's story.
Without power.
Without plot armor.
Without any cheat ability.
Her future seemed completely hopeless.
---
However…
Fate was not entirely cruel.
When Tsukiko turned six years old, something incredible finally happened.
A system appeared.
A cold mechanical voice echoed inside her mind.
And the first mission it gave her made Tsukiko suspect the system was a huge fan of Naruto and Sasuke.
---
[S-Rank Core Mission]
Raise Naruto Uzumaki and Sasuke Uchiha until they reach the age of twelve.
Give them a different and happier childhood.
Reward: Become the richest person in the entire Ninja World.
---
Tsukiko stared at the mission for several seconds.
Then she clicked her tongue in annoyance.
"What kind of ridiculous mission is this?"
She scrolled through the mission list inside her mind.
"Are there any easier ones?"
Soon, two other missions appeared.
And these two were much more interesting.
---
[B-Rank Mission]
Defeat Uchiha Itachi once.
Reward: Activate Three-Tomoe Sharingan.
---
[A-Rank Mission]
Beat Uchiha Itachi once every week for one year.
Reward: Random Mangekyō Sharingan ability.
---
Tsukiko slowly turned her head.
Her gaze landed on a small figure nearby.
A four-year-old boy was sitting peacefully on the wooden veranda, eating a skewer of three-color dumplings.
The boy looked innocent and completely harmless.
Uchiha Itachi.
Tsukiko stared at him quietly.
Then she whispered softly.
"Forgive me, Itachi…"
"Sister Tsukiko promises this won't be the last time."
---
Tsukiko took a deep breath.
Her small hands slowly clenched into fists.
Even though she felt guilty, she couldn't ignore this opportunity.
Because in the ninja world, strength meant survival.
Without power, she would simply die during the massacre.
But if she awakened the Three-Tomoe Sharingan…
Her chances of survival would rise dramatically.
Even if the method was slightly unethical.
---
Itachi sat peacefully, chewing dumplings like a tiny hamster.
When he heard footsteps approaching, he looked up.
His big eyes reflected Tsukiko's figure.
At this moment, Itachi was only four years old.
His face still had baby fat, and a small drop of syrup remained at the corner of his mouth.
He looked extremely soft and harmless.
Nothing like the future ninja who would one day destroy the entire Uchiha clan.
"Sister Tsukiko?" Itachi asked innocently.
He lifted the dumpling skewer.
"Would you like one?"
Tsukiko suddenly shouted.
"Eat what?!"
Then she launched forward like a small leopard.
---
BAM!
The peaceful afternoon instantly turned chaotic.
Tsukiko rushed forward and tackled Itachi without hesitation.
Because of her size advantage and the element of surprise, the four-year-old genius was caught completely off guard.
Before Itachi could react, Tsukiko had already grabbed his collar.
She slammed him onto the wooden veranda.
The wooden boards creaked loudly.
The dumplings flew out of Itachi's hand and rolled into the bushes.
Covered in dirt.
"Sorry, Itachi!" Tsukiko shouted dramatically.
"This is for the peace of the ninja world!"
"And for my future!"
Then she started punching.
Of course, it wasn't a serious fight.
It was simply a chaotic children's brawl.
Still…
Tsukiko was six years old.
Itachi was only four.
The difference was overwhelming.
Itachi struggled helplessly beneath her.
His face turned red.
His eyes filled with confusion.
"S-Sister Tsukiko…"
"It hurts…"
His tiny voice struck Tsukiko's conscience like a knife.
For a moment, she almost stopped.
But then—
A mechanical voice sounded in her mind.
---
[Mission Condition Completed]
Host has successfully defeated Uchiha Itachi.
B-Rank Mission Cleared.
Reward Issued: Three-Tomoe Sharingan Activated.
---
A burning sensation suddenly spread through Tsukiko's eyes.
Her vision sharpened instantly.
She could see every detail around her.
Even the tiny tears forming in the corner of Itachi's eyes.
A powerful feeling surged through her body.
Tsukiko released Itachi and sat beside him.
Her heart was beating rapidly.
She had done it.
She had awakened the Three-Tomoe Sharingan.
---
Meanwhile, Itachi slowly sat up.
He brushed the dust off his clothes and looked sadly at the ruined dumplings in the bushes.
Then he looked at Tsukiko.
"Sister Tsukiko…"
"Were you doing ninja training just now?"
Tsukiko coughed awkwardly.
"Of course!"
"This was practical ninja training!"
"The enemy won't wait for you to finish eating dumplings!"
She even patted his shoulder like a wise teacher.
But inside her mind, she was already planning the next step.
After all…
There was still that A-Rank mission.
---
And so…
One year passed.
---
On the final day of that year, Tsukiko stepped into the training field.
Her eyes immediately locked onto a familiar figure.
Five-year-old Itachi was sitting quietly on a stone bench.
He was carefully opening a box of natto.
Tsukiko smiled.
Today was the final battle.
As long as she defeated him one more time…
She would obtain the Mangekyō Sharingan.
---
Before Itachi could take his first bite, he suddenly froze.
His instincts screamed danger.
Over the past year, this feeling had become very familiar.
He slowly turned his head.
And saw Tsukiko walking toward him.
His face instantly turned pale.
"S-Sister Tsukiko…"
"Isn't the training supposed to be on Saturday?"
"Why is it today?"
His voice trembled.
Tsukiko cracked her knuckles.
"Schedule change."
"Special training starts now."
---
Moments later—
BOOM!
Itachi was once again pinned face-down in the sand.
"Sister Tsukiko…"
"The place you hit last time is still swollen…"
Itachi whispered helplessly.
Tsukiko raised her fist.
Then gently tapped his shoulder.
"Last time, Itachi."
"I promise this is the final training."
---
Suddenly, the system voice appeared again.
---
[A-Rank Mission Completed]
Perfect Attendance: 52 Weeks of Beating Itachi Achieved.
Reward Granted: Mangekyō Sharingan Awakening.
---
A terrifying burning sensation erupted in Tsukiko's eyes.
She squeezed them shut as pain surged through her body.
When she opened them again…
The world changed.
Her pupils transformed.
The three tomoe twisted together into a mysterious scarlet pattern.
Her Mangekyō Sharingan had awakened.
---
Itachi stared at her in shock.
"Sister Tsukiko…"
"Your eyes…"
"Why do they look like that?"
Tsukiko panicked.
If the Uchiha clan discovered she awakened the Mangekyō at six years old, her peaceful life would be over.
So she immediately turned off her Sharingan.
Then she laughed awkwardly.
"That was just a new Genjutsu I invented!"
"The Ultimate Red-Eye Staring Technique!"
Itachi looked at her silently.
Clearly unconvinced.
But he didn't argue.
Instead he sighed and asked one final question.
"Sister Tsukiko…"
"Does this mean the special training is finally over?"
Tsukiko waved her hand while walking away happily.
"Relax."
"I won't beat you up anymore."
---
Behind her, Itachi looked down at the natto box covered in sand.
He hesitated.
Then he tried to stand up.
But his legs had gone numb.
THUD.
He fell flat on the ground.
---
And somewhere in the distance…
Tsukiko laughed happily.
Because she had just taken the first step toward her ultimate goal.
Becoming the richest person in the entire ninja world.
