One Piece: Scientist Simulator

Prelude to Battle

February 27, 1520

Six years had passed in the blink of an eye since the lunar adventure. Those years were marked by relentless progress, quiet planning, and a cautious peace—yet a faint shadow lingered over Edie's thoughts. This was the year the plot of One Piece would begin, but more pressingly, it was the day foretold in Edie's simulation: the return of Imu, the ancient sovereign of the world.

As the dawn broke over Mariejois, the Holy Land stood on edge. At the heart of this tension lay a solitary, impenetrable structure—a dark, doorless house prepared specifically for Imu's arrival. Its purpose was both to contain the returned entity and serve as a battlefield for the unimaginable clash to come.

Edie stood at the forefront of this storm, silent and calculating as always.

The Gathering of Forces

The coalition government had mobilized its entire might, a testament to the gravity of the situation.

Surrounding the structure, twelve figures stood resolute—the Twelve Earthly Branches, alongside the three space hybrid clones born of the moon's elemental aliens. Positioned in groups of three, they guarded the four cardinal directions, a living fortress of power.

Above, the sky roared with elemental energy. Kaido, in his Azure Dragon form, circled ominously alongside Big Mom, who rode the electrifying Zeus, her soul-imbued thundercloud.

The Marines, too, had assembled in full force. Fleet Admiral Momousagi led the charge, flanked by the three Logia Admirals and former legends—Sengoku, Garp, Zephyr, and Tsuru. This was a united front of unprecedented scale, their combined strength enough to shift the tides of history.

Despite this, Edie remained unimpressed.

"It's not necessary. I'm enough on my own," he said with quiet confidence, shaking his head.

"Edie, don't underestimate Imu," Momousagi replied firmly. Her tone was stern, but beneath it was a glimmer of worry for the man who had become a cornerstone of the New Era.

Edie raised his hand dismissively. "You'll remain outside. This battle is mine to fight."

Without another word, he approached the structure. With a gentle push, a door seamlessly materialized in the wall and swung open. As he stepped inside, the door closed silently behind him, blending back into the featureless surface.

Within the Void

The room was a void darker than the deepest abyss. It was an oppressive blackness that devoured even the faintest trace of light, an environment designed to strip away all distractions and concealments. Here, no tricks, illusions, or external forces could interfere.

Edie stood alone in the suffocating silence, the sound of his steady footsteps echoing faintly.

"Eight minutes left..." he murmured, his voice cutting through the void.

For this moment, he had prepared for six years, his mind and body pushed to the pinnacle of what could be achieved. Through the Soul Tower, he had condensed six pure soul crystals, absorbing them to bolster his very essence.

600 billion energy level.

That was his current state—a level far surpassing even the most powerful Admirals and Emperors of the seas.

Yet, even this immense power had reached its natural limits. The sixth crystal had only elevated his energy marginally, from 598 billion to 600 billion. It was a humbling reminder that there were boundaries to even the most extraordinary forms of enhancement.

Still, Edie was undeterred. "There are always other ways to surpass limits," he thought, clenching his fists in the darkness.

Memories and Reflections

As the seconds ticked by, Edie's mind wandered to the events that had shaped these years of preparation.

Four years ago, the Sea Train Project connecting islands in the East Blue and New World had been completed by Tom and his Studio, a marvel of engineering that revolutionized trade and travel.

Three years ago, a conversation with Dragon had yielded an unexpected alliance. By proposing an anti-corruption role for the Revolutionary Army within the coalition government, Edie had paved the way for a tenuous yet functional collaboration.

Two years ago, Judge's Germa Kingdom had rejoined the coalition government. Under Edie's guidance, it reclaimed the core of its former empire, with Judge's daughter joining Edie's institute to further scientific innovation.

And only a year ago, Uta's concert in Water 7 had brought together allies and rivals alike. Even Shanks, a certified adventurer now, had reconciled with Uta, reigniting familial bonds that once seemed irreparable.

The Final Countdown

"One minute left..."

Edie's thoughts turned to his companions—those who had undergone the Immortality Surgery and remained pillars of his journey: Hancock, Momousagi, Yamato, Robin, Kaido, Ginny, Vegapunk, Whitebeard, and Uta. Each had played a role in his adventure.

As he stood in the endless void, the weight of their trust and expectations pressed upon him. He closed his eyes briefly, his mind steadying.

The Final Confrontation

The room was a suffocating void, darker than the deepest abyss, as Edie stood motionless, his hand resting lightly on the hilt of Yoshi. The blade hummed faintly, alive with the essence of the Soul-Soul Fruit, its edge imbued with fragments of countless defeated demons.

"Three seconds…"

His voice was a whisper, lost in the oppressive silence.

"One second."

As the countdown reached its end, the void was split by a flash of blinding white light. From the epicenter of that radiance, a figure emerged—a being torn from time itself.

Imu.

The former sovereign of the world appeared as if plucked from the moment of her obliteration by [White]. Her body was charred and bloody, yet already knitting itself back together, her eternal essence defying mortality. Her gaze was sharp, her memory frozen at the instant of her disappearance.

Her lips moved, the single word that escaped them laced with venom:

"Time Fruit."

Her Observation Haki flared, sweeping the surroundings. Yet in this dark expanse, it was as though she were blind—her senses muted, her awareness blocked. Confusion flashed in her eyes.

Suddenly, her body jolted. A sharp, searing pain tore through her chest.

She looked down in disbelief to see a blade—a blackened, cursed blade—protruding from her heart.

"What…?" Blood spilled from her lips as a foreign energy began invading her very essence. It wasn't just her body that was pierced; her soul itself was being corrupted. She staggered, coughing violently.

From the shadows behind her, a voice echoed, calm yet resolute.

"I have been preparing for this day for a long time."

Edie's grip on Yoshi tightened as he pushed the blade deeper. "This room," he began, his tone eerily steady, "is a product of years of research. It absorbs ghost particles and drains Haki. The more you use, the weaker you become. There is no recovery here, no reprieve."

Imu gasped, her mind racing. "You… How could you have known the precise moment of my return?"

Her voice trembled with disbelief. She had defied the natural flow of time, her return veiled in an impenetrable shroud of temporal chaos.

Edie's expression didn't change. "I didn't. I simply never left."

(Not really, Edie just thought it would sound cooler 😂)

Realization dawned on her like a blow. He waited. For years, he had waited, unmoving, unyielding, for this exact moment.

Imu's body shook as she tried to summon her power, but a wave of despair washed over her. "The Five…" she muttered weakly.

"Dead," Edie interrupted coldly. "And now, so are you."

Imu's eyes burned with fury, glowing an unnatural red. Her body convulsed as she began to transform, the boundaries of her human form dissolving.

"Your time is over, Imu," Edie said, his voice unwavering. "The world has moved on. The Celestial Dragons are no more. The era of the Coalition Government has begun."

He pulled Yoshi free with a sharp motion.

Imu screamed—a sound that wasn't human but a guttural roar of a demon. Her true form revealed itself in her final moments: a towering, four-clawed black dragon, its wings spreading wide enough to blot out the sun.

The room, already straining against her immense presence, collapsed under the force of her transformation.

Outside the Void

As the structure crumbled, the gathered forces outside froze, their eyes locked on the rising chaos.

"Prepare for battle!" Hancock shouted, her voice cutting through the tension.

But before anyone could move, Edie emerged from the ruins, his steps steady, his face emotionless.

Behind him, the massive dragon—a symbol of Imu's once-unmatched power—was collapsing into wisps of black smoke. Her form disintegrated into nothingness, her voice echoing one final curse:

"Edie! Curse you! Even in death, your soul will perish forever!"

It was not her voice that spoke, but the roar of the Sea Devil itself—a primal force tied to her existence. Yet even that faded as her body turned to dust and scattered into the wind.

Edie stopped, turning to glance at the fading remnants. "Dead," he said simply, as if to reaffirm the finality of it. "It's all over."

The tension broke as the gathered forces began to lower their weapons. Momousagi let out a long breath, her shoulders relaxing.

"She's really dead…" she murmured, disbelief coloring her tone.

Kaido landed with a thunderous crash, shifting back into his human form. His grin was wide, his eyes gleaming with disappointment. "What a waste. I came all this way for a fight."

Edie glanced at him, his tone dry. "You'd only get in the way."

Kaido laughed, loud and booming, but there was no malice in it.

Momousagi stepped forward, giving Edie a small nod. "We'll return to headquarters and ensure everything is secure. Thank you, Edie."

Edie inclined his head slightly. As she turned to leave, he looked back at the empty space where Imu had fallen.

"Farewell, Ruler of the Celestial Dragons."

The words hung in the air as he sheathed Yoshi, the soft click of the blade marking the end of an era. The world, once gripped by Imu's shadow, now belonged to the Coalition Government—and to Edie, the man who had waited patiently in the dark for the dawn to break.
