That night, Akemi sat on the rooftop, staring at the moon as he sipped from a bottle of sake.
"Sixteen years already…"
He had once been an ordinary student on Earth—until an accident sent him into the Naruto world, reborn as a baby of the Uchiha clan.
Excitement quickly turned to despair when war took his parents, leaving him an orphan. To survive, he trained relentlessly, awakening his Sharingan at just one year old—and by age four, his Mangekyō Sharingan.
His Mangekyō's ability mirrored Shisui's Kotoamatsukami in uniqueness: dimensional travel.
Each eye could lock onto a world as an anchor, allowing him to traverse between dimensions safely.
His first jump had taken him to the world of Demon Slayer, where he joined the Demon Slayer Corps, mastered every breathing style—including the Sun Breathing—and helped defeat Muzan Kibutsuji.
From that world, he brought back mastery of swordsmanship and the power of breath—making him one of the strongest in the Shinobi world.
He earned the title Sword God—Uchiha Akemi, rivaling even the Yellow Flash in fame.
But when Obito attacked Konoha with the Nine-Tails, Akemi was forbidden by the Hokage to intervene—watched day and night by ANBU. The elders feared his power more than they feared the beast.
When the village was destroyed and Minato died, the people—stirred by propaganda—blamed Akemi, claiming he had controlled the Nine-Tails.
He didn't bother to explain. The truth was obvious to those in power, yet no one stepped up to clear his name.
So he stopped caring. If the village wanted a villain, he would give them none of his loyalty.
After the Nine-Tails incident, he became a recluse—spending his time traveling to other worlds to hone his skills.
The One Piece world was the most recent one he'd discovered. He hadn't even explored it fully before the Uchiha coup forced his hand. Now, bringing his clan here had been the best move possible.
Here, they were free—no longer under the heel of Konoha's hypocrisy.
As he smirked to himself, a sudden chime rang in his mind.
[Ding! Host detected as adult! System activation commencing!]
[Clan Revival System successfully initialized!]
[Main Quest: Find a new homeland for the Uchiha Clan.]
[Reward: Single-Tomoe Sharingan.]
"…"
Akemi blinked, then chuckled. "Well, it's about time."
When Akemi heard the voice of the system echoing in his mind, he was completely stunned.
What the hell?!
He actually had a system?!
When he was just born, he had wondered if he might have one. After all, for transmigrators, a system was practically standard equipment in web novels.
But no matter how much he shouted or acted out back then, there had never been any response. Eventually, he gave up on the idea entirely.
Reaching his current level, everything he achieved was through his own strength.
In the entire shinobi world, there were only a handful of people he couldn't kill.
And now he finds out—he actually does have a cheat system?!
And what's with this "one-tomoe Sharingan" reward?
He'd already awakened his Mangekyō Sharingan ages ago. Giving him a one-tomoe version now was something even a dog wouldn't want.
"System, do you even know what level my Sharingan is?"
[Sharingan: Mangekyō.]
"Then why would you give me a one-tomoe Sharingan? Can't you change the reward?"
[This is a main quest reward. It cannot be modified or declined.]
[Failure penalty: Unable to unlock new system functions.]
Akemi's mouth twitched.
What a waste! Absolutely useless!
Normally, any transmigrator with a system—the so-called ultimate golden finger—should be thrilled. But this system? It just felt pathetic.
It was like he was already at endgame level, fully equipped, and the system wanted him to start from Level 1 all over again—grateful for scraps of pity.
Forget it!
He'd been through all kinds of storms over the years. Since he needed to find a base for his clan anyway, he might as well finish this quest along the way.
In the end, everything still came down to his own strength. The system might be impressive, but relying on it to grow to this point? That took him nearly ten years.
He had planned to spend his sixteenth birthday drinking sake and watching the moon in peace.
Instead, he got this as a birthday present.
If he had to describe his feelings in one word—
Damn!
Akemi raised his middle finger at the full moon and went to sleep.
---
The next morning, the Uchiha clan was awakened by a commotion.
"The Snake Princess has returned!!"
"The Snake Princess is back!!"
The shouting echoed across the settlement, and everyone looked out toward the harbor.
"What's going on?"
Akemi smiled faintly. "Looks like the main figure's back. Shisui, Itachi, let's go greet her."
"Open the gates—!!"
The massive iron gate slowly swung open, revealing a pirate ship drawn by two giant pythons, gliding into the harbor.
"Snake Princess, welcome back!"
"Welcome home!!"
"Great work, Kuja Pirates!!"
Villagers lined the streets, cheering loudly.
"A huge haul again—gah hahahaha!!"
"Lady Aland! Lady Kiku!"
"So cool… I want to join the pirate crew when I grow up!"
Excited young girls stared in awe at the crew on deck.
Then an even louder cheer erupted as a woman descended from the ship.
She had long jet-black hair, deep blue eyes, a flawless face, and golden snake-shaped earrings.
Her beauty was so breathtaking that anyone who looked at her couldn't help but fall under her spell.
She was none other than the "World's Most Beautiful Woman," Pirate Empress—Boa Hancock.
"The Gorgon Sisters!"
"Lady Marigold!"
"Lady Sandersonia!"
"Lady Snake Princess!"
"She's so beautiful I think I just forgot who I am!"
A woman stepped forward respectfully. "You've worked hard, my lady. Your palanquin is ready."
"Has anything happened recently?"
Several warriors' faces stiffened. Amazon Lily strictly forbade men from entering, and the Empress detested men more than anyone. If she found out there were men here, she'd fly into a rage.
Hancock instantly sensed something was wrong. "It seems something has happened. Speak! What is it?!"
Just then, three figures appeared on the street, drawing everyone's attention.
"Who are they?!"
"Greetings, honored Snake Princess. We are—"
Before Akemi could finish, Hancock's expression darkened. "Men?!"
"Men?!"
"There are men here?!"
"How could there be men on Amazon Lily?!"
Everyone was in an uproar.
"Men have set foot on sacred Amazon Lily—and entered Amazon City itself! Guards! Capture them, Kuja Pirates!!"
As soon as her order fell, several warriors rushed forward.
Shisui and Itachi instantly stepped up.
Bang! Bang!
Within moments, the attacking women were knocked out cold.
"What?!"
Everyone was shocked. Those were members of the Kuja Pirates—the most elite warriors of Amazon Lily! And yet they were defeated instantly.
The rest raised their weapons, brimming with killing intent, waiting for the Empress's command to turn Akemi and the others into pincushions.
"Whoa, whoa, ladies—no need to be so passionate. That's not how you welcome guests!"
Akemi raised his hands in surrender.
"Man, speak honestly. Who are you? Why are you here? How did you enter our island?"
Seeing his gesture, Hancock held off for the moment.
"My name is Uchiha Akemi. These are my brothers, Uchiha Shisui and Uchiha Itachi. We're from the Uchiha clan. Due to certain events, we had to migrate. Coming here was purely an accident."
