The moment Akira spoke, the system responded.
[Retrieving One Piece Simulation Memories…]
The instant those words appeared, only Akira felt it.
A strange anxiety rose in his chest—like something long forgotten was suddenly clawing its way back into his mind.
Akira closed his eyes.
For the next ten minutes, time felt distorted.
Memories flooded in relentlessly—vast oceans, endless islands, strange flags fluttering in the wind, laughter, freedom, ambition, and dreams that burned brighter than chakra itself. Kingdoms rose and fell. Pirates chased impossible ideals. Men challenged the sea, the sky, and even fate.
When the memories finally settled, Akira slowly opened his eyes and looked up at the moon hanging quietly in the sky.
"…I still don't really know what One Piece is," Akira muttered to himself.
But then a faint smile appeared.
"Still… that life wasn't bad at all. I got to see things I never would have otherwise. Different worlds, different dreams."
He exhaled softly and turned his attention back to the system.
"Alright," Akira said. "Give me the rewards."
This time, there was no list. No selection panel.
Instead, a single message appeared.
[Enhanced World Simulation – One Piece]
[Reward Acquired: Blank Devil Fruit]
Akira blinked.
"…A blank Devil Fruit?"
Confused, he immediately questioned the system.
"What is a blank Devil Fruit?"
The system responded without delay.
[A Blank Devil Fruit grants one Devil Fruit slot.]
[After consumption, the user will awaken the Devil Fruit ability that aligns most strongly with their deepest desire.]
Akira's expression turned thoughtful.
"So that's how it works…"
He recalled something he had once heard a theory in his previous world—that Devil Fruits were born from human desire, from wishes strong enough to distort reality itself. Fire, ice, dragons, gods… every absurd power traced back to a single yearning.
His fingers slowly curled.
"Then this is no different," he concluded quietly.
"Just a crystallized desire… waiting to take form."
Just then, Akira frowned slightly as the thought surfaced.
"Hey System, you once told me that rewards require proximity to a massive energy source…
So why now?
Is there some condition I'm missing?"
As if responding to his doubt, the system replied calmly.
[ Formation and consumption of the Blank Devil Fruit does not require an external energy source.
However, transforming the Blank Devil Fruit into a specific Devil Fruit ability requires energy.
The greater the energy provided, the higher the quality and authority of the resulting ability.]
Akira's eyes narrowed slightly as he processed the information.
"So it works like this…" he murmured.
If someone simply desired fire, they would obtain fire.
But fire itself had levels.
Just like how ordinary fire-style chakra and Six Paths–level fire were fundamentally different despite sharing the same nature.
A low-level fire ability could burn forests.
A higher-level one could burn countries.
A god-tier one could burn a world itself.
It wasn't just about possessing the power—but about authority, depth, and understanding.
Akira exhaled slowly.
"That makes sense."
He nodded to himself.
"System, retrieve the Blank Devil Fruit."
The space before him rippled lightly, and a moment later, a fruit appeared in midair.
It looked like a simple apple—pure white, smooth, flawless.
No spirals.
No strange patterns.
No ominous aura.
Almost… ordinary.
Akira examined it carefully.
"So this is it," he said quietly.
Perhaps because it wasn't yet bound to any desire, it hadn't taken any strange form.
He closed his eyes, raised the fruit, and took a bite.
There was no terrible taste.
No backlash.
No violent surge of power.
Nothing dramatic happened at all.
The fruit dissolved into light the moment it touched his lips.
Akira opened his eyes slowly.
"…That's it?"
Just then, a system message echoed in Akira's mind.
[Confirm Ten-Tails as the source of power?]
Akira did not hesitate.
"Yes," he answered calmly.
The moment he nodded, both Akira and the Ten-Tails were enveloped by strange, invisible fluctuations. The air itself twisted, space bending as if reality had momentarily lost its structure.
From a distance, Madara, Nagato, Sasuke, Kakashi and the others all turned sharply toward where Akira had been.
A second ago, they could clearly sense Akira's presence—his chakra, his existence, unmistakable.
Now… there was nothing.
No chakra. No life force. No spatial anchor.
Only a distorted region of space remained, warping faintly like heat above molten lava.
Madara narrowed his eyes.
"So it's begun…"
Without another word, each of them left this world and returned to Akira's world, carrying with them the weight of what they had just witnessed.
Akira, meanwhile, felt nothing.
The instant he confirmed the Ten-Tails as the power source, his consciousness was torn away—not violently, but completely. Thought, sensation, even time itself faded into darkness.
There was no pain.
No dream.
No sense of self.
Only silence.

VIVIENNE World
Ryōkai City – City of Twin Realms
Three months had passed—and in that short span of time, profound changes swept across not just one world, but multiple worlds.
The first and most symbolic change was that both worlds finally received their official names.
Akira's world came to be known as Chronarch World, named after Chronarch, the God of Space-Time.
The other world was named Vivienne World, after Vivienne, the Goddess of Life who gave life to people.
The second major change was the birth of a city unlike any other.
Ryōkai City — the City of Twin Realms.
Built around the permanent space-time gate, Ryōkai City existed in two phases simultaneously.
One half of the city lay within Chronarch World, while the other half manifested in Vivienne World.
Though separated by worlds, the two halves were perfectly synchronized, mirroring one another in structure and function.
Ryōkai City served multiple purposes.
It was a fortress, guarding the space-time gate and ensuring that only authorized individuals could pass between worlds.
It was a checkpoint, a vast transitional domain where travelers could prepare themselves before stepping into another reality.
And most importantly, it was a bridge—a living symbol of connection between worlds that were once completely isolated.
In just three months, Ryōkai City had already risen to prominence.
In Vivienne World, it became the most popular and influential city almost overnight.
In Chronarch World, it stood second only to the main headquarters of the Imperial Council of Shinobi.
Merchants, scholars, shinobi, diplomats, and explorers from countless regions gathered there, drawn by curiosity, opportunity, and the promise of something greater.
A new era had quietly begun—
one built not on war, but on convergence.

Today, Akira finally gained consciousness and opened his eyes.
After opening his eyes, Akira noticed that his surroundings had changed. Or rather, a city had been built a few kilometers away from his location.
Although it was still a desert, tens of thousands of trees had been planted both inside and outside the city. Just by looking at it, Akira could feel its grandness and mightiness. It looked many times bigger than the original Konoha and was only slightly smaller than the current Konoha—the capital of the Imperial Council of Shinobi.
After checking the surroundings and everything around him, Akira then looked inward and checked what had changed.
This was because the Ten-Tails had disappeared at some point, and Akira could not feel the presence of the Ten-Tails anywhere within the range of his senses.
The first thing Akira noticed was that his chakra had expanded. Although it had already been almost infinite before, now it had grown even more. Along with that, his strength and overall capabilities had also increased further.
After confirming all of this, Akira finally focused his attention on the Devil Fruit power that he had gained.

Devil Fruit Name : Karma Karma no Mi
Type: Paramecia (Conceptual)
Description
The Karma Karma no Mi grants its user authority over souls, reincarnation, and the law of cause and effect.
Upon awakening, the user can perceive the complete karmic record of any soul—every action, sin, virtue, and consequence accumulated across a lifetime.
The fruit allows the user to judge souls and determine the conditions of their next reincarnation, ensuring that every action is repaid in kind.
Good deeds yield favorable rebirths; cruelty and murder result in suffering across future lives.
Through this power, karma becomes absolute law—inescapable, impartial, and eternal.
In the hands of a godlike being, this fruit can govern the reincarnation cycle of an entire world.
