Sign-In System: One Piece, Demon Slayer & Beyond

"This is… the Tenseigan Eye."

Ron murmured to himself, his mind suddenly flooded with an influx of knowledge and information.

[Perfect-Grade Tenseigan Eyes: The ultimate evolutionary form of the Byakugan, having reached its absolute peak. A flawless supreme ocular ability, embodying the powers of destruction and creation.]

[Abilities:

1. Yin-Yang Release: The power to create and shape all things, capable of forging the legendary Truth-Seeking Orbs.

2. Mastery Over Gravity & Repulsion: The ability to manipulate attraction and repulsion at will.

3. Dimensional Control: Grants teleportation and influence over space itself.

4. Vitality Absorption & Mind Control: Can drain the vitality of others and impose absolute will upon others.

5. Life Bestowal: Infuses energy into constructs, granting them autonomous existence.]

[Truth-Seeking Orb: A small black sphere containing the combined essence of all elemental forces—capable of obliterating everything it touches.]

[Green Chakra: A unique power formed from the perfect fusion of spiritual energy and physical vitality. This is the core energy source that fuels the Tenseigan Eyes.]

With just a single thought—

A flicker of divine radiance flashed through Ron's pale blue eyes.

Before him, a small black sphere about the size of a fist materialized, floating quietly in midair—a Truth-Seeking Orb.

Ron shifted his gaze downward toward a massive mountain on the uninhabited island below.

With the flick of a finger, the orb shot forward like a streak of black lightning—

BOOM!

A thunderous explosion erupted as the Truth-Seeking Orb made contact.

In an instant, the towering several-hundred-meter-tall mountain was completely erased from existence.

Nothing remained.

No rubble, no debris—just an enormous, gaping crater.

Ron's eyes flickered as he observed the result.

"So it does consume some of my spiritual energy and vitality… I see now. This green chakra is the result of combining both forces into a singular power source."

At that moment, he finally understood why unlocking the sealed Tenseigan Eyes required such strict conditions.

Three years of constant energy accumulation and refinement—

It was all meant to provide a vast, nearly immeasurable amount of chakra to awaken these eyes.

He could feel it—the sheer power coursing through his Perfect-Grade Tenseigan had transcended its origins, reaching a level that rivaled, if not surpassed, the legendary Rinnegan itself. Techniques once thought exclusive to the Six Paths—Universal Pull, Almighty Push, and even Planetary Devastation—manifested effortlessly at his command.

Ron then proceeded to test these abilities.

1. Universal Pull (Banshō Ten'in)—worked effortlessly.

2. Almighty Push (Shinra Tensei)—devastating in its destructive power.

3. Planetary Devastation (Chibaku Tensei)—activated flawlessly.

And to his surprise—

The chakra consumption was far lower than he had anticipated.

By the time he had finished testing every single ability—

The island itself had completely vanished from the ocean's surface.

Not even a single trace of its existence remained.

Dressed in his flowing black robes, his long hair swaying with the wind, Ron now stood on the surface of the vast sea.

His eyes closed as he carefully sensed the immeasurable power flowing within him.

A faint smile formed at the corner of his lips.

"So this is the power beyond even the Four Emperors…"

He murmured softly.

Strength—

A level of strength he had never felt before.

For the first time, Ron could fully grasp the extent of his own power.

"These three years of intense cultivation… were not wasted."

His vision slowly returned—

His pale blue irises gleamed brilliantly under the sunlight.

The world… had never looked so clear.

Even the scenery thousands of miles away was now visible to him as if he stood right in front of it.

His vision was no longer bound by any limitations.

At this very moment, his vital energy surged like a mighty dragon, coursing through his body in an endless, unstoppable current.

His mind was sharper, his control over his body—absolute.

Peak condition.

Absolute dominance.

Before him, Admirals, Four Emperors—none of them were worth considering.

Even if two Emperors joined forces against him—

He wouldn't even flinch.

Lifting his gaze, Ron looked up at the vast blue sky.

His vision stretched beyond the atmosphere, allowing him to see the countless meteors suspended in the void of space—

And even further beyond—

He could clearly see the fragmented remains of the ancient moon.

"A certain blind man can pull meteors from the sky with his Gravity-Gravity Fruit."

Ron muttered to himself.

"Now, I wonder… If I push my powers to their limits… Could I pull the moon down as well?"

A playful smirk spread across his lips.

Of course—

That was nothing more than a passing thought.

With the power he wielded now, he had countless methods of destruction.

There was no need to waste effort dragging down the moon.

Ron slowly turned his gaze toward the Red Line.

Toward the legendary Holy Land—

Mary Geoise.

"Next… it's time to pay Mary Geoise a visit."

His smile deepened.

"Whether it's the Five Elders… or that so-called Imu…"

"I sincerely hope you can provide me with a decent challenge."

"Don't disappoint me."

With a simple thought, the space before him distorted—

And in the next moment—

Ron stepped forward, vanishing into the void.

…

When Ron reappeared before Hancock, Rayleigh, and Kuina, his presence alone caused an immediate shift in the atmosphere.

Everyone's eyes widened in shock as they gazed at the figure before them—

His once-dark eyes had transformed into a pair of mesmerizing blue irises that seemed to shimmer with an otherworldly light.

The sheer pressure radiating from his body was terrifying beyond words.

It wasn't just overwhelming—

It was suffocating.

Hancock, Rayleigh, Robin, Kuina—none of them had ever felt anything like it before.

"Ron…?"

"Is that really you, Captain?"

Robin, Conis, and Bonney stared at him in disbelief.

He had only been gone for one day, yet somehow, he felt like a completely different person.

How could someone change so much in such a short amount of time?!

"Master… your eyes—are they healed?", Enzo widened his eyes in astonishment.

Kuina, too, was completely captivated, her gaze locked onto Ron's piercing blue irises.

"This pressure…"

Hancock clenched her fists, her expression unusually serious.

Even she, the Empress of Amazon Lily, had never experienced such an immense aura before.

Beside her, Sandersonia and Marigold were already drenched in cold sweat.

The sheer dominance in Ron's presence weighed down on them so heavily that their knees threatened to buckle beneath them.

A terrifying instinct clawed at the back of their minds—

A primal urge to submit.

"Ron, kid… you are still Ron, right?", Rayleigh finally spoke, his tone carrying an uncharacteristic trace of hesitation. "What the hell happened to you?"

Ron let out a small sigh.

"I suppose you could call it a breakthrough in my strength," he said, shaking his head slightly. "The surge in power is so massive that I can't fully contain my aura yet."

Hearing this, everyone felt their hearts pound.

A breakthrough?

Again?!

"You're telling me… in just a single day… you got even stronger?!"

Rayleigh stared at him, utterly speechless.

"You… You freaking monster!"

"Exactly!" Bonney exclaimed. "What the hell kind of training did you even do?! This is just ridiculous!"

Robin took a deep breath, her sharp eyes fixated on him.

"And your eyes… they weren't like this before."

"Yeah, Master! Your eyes… they turned blue all of a sudden!"

"Captain…"

Everyone was completely rattled by his transformation.

But Ron—

Ron simply smiled, his blue eyes shimmering.

He didn't bother answering.

…

Meanwhile… In the Florian Triangle.

A dark and eerie fog loomed over the ocean, shrouding the ruins of Thriller Bark—

A once-massive floating island, now left in shambles, ever since Ron annihilated a third of it with a single kick years ago.

And yet—

Deep within the haunted ruins, sinister shadows lurked.

At this very moment, the Straw Hat Pirates—along with Brook—were locked in an intense battle.

"Straw Hat Pirates…!"

A sharp, piercing voice echoed through the fog, dripping with malice.

"Surrender your shadows to me!"

From within the gloomy castle, the warlord Gecko Moria cackled menacingly, his hulking frame shrouded in darkness.

At his command, an army of undead creatures surged forward—

The Ghost Princess, Perona, along with the Invisible Man, Absalom, led a horde of zombies, launching a relentless assault on the Straw Hat crew.

Steel clashed against bone.

Explosions lit up the darkness.

The battle erupted into chaos.

And yet, amidst the raging war—

A certain figure sat lazily on the Sunny's deck, completely unbothered by the carnage unfolding before him.

Lounging casually with one leg draped over the other, a can of cola in hand—

Enel—the self-proclaimed God of Skypiea—merely watched.

His expression?

Pure boredom.

"Man… this is so damn dull."

He sighed, taking another sip of cola.

"Are all the people in this ocean this weak?"

Lifting a finger, he lazily flicked his ear—his golden earrings jingling as he did so.

…

Moments later—

Moria's sinister grin widened as he stole Luffy's shadow, injecting it into the massive Oars, the legendary demon corpse.

With a deafening roar—

Oars came to life.

In a single move, the Straw Hat crew was completely overwhelmed.

One by one, they were sent flying, struggling to hold their ground.

The monstrous laughter of Gecko Moria filled the night.

Victory was within his grasp.

And yet—

Despite everything, Enel remained exactly where he was.

Unbothered.

Unmoved.

He watched Luffy and the others get torn apart by Oars and Moria…

And still, he did nothing.

As if he simply didn't care.

"…Yeah, no."

He exhaled, shaking his head.

"This is way too boring."

To him, whether Luffy and his crew lived or died was of no concern.

Sitting within the massive frame of Oars, Gecko Moria gazed down at the defeated Straw Hat crew, his voice filled with unrestrained arrogance as he let out a sharp, triumphant laugh.

"Hehihihihi! Do you see now? This is the invincible power of Oars the Demon! This is the strength I have pursued for so long!"

"As long as he continues to grow stronger, not only will I crush weaklings like you, but one day, I will take my revenge on that bastard Ron and Kaido! Just you wait! Hehihihihi…"

From a distance, Enel, who had been lounging idly on the Straw Hats' ship, lazily sipping on a bottle of cola, narrowed his eyes slightly at the mention of that name.

"Oh?"

A flash of lightning.

In the blink of an eye, Enel, wielding his golden staff, appeared right in front of Oars, his presence crackling with electricity.

"W-Who are you?!"

Moria, startled by the sudden appearance of the intruder, tensed up and glared at him with caution. "Are you one of the Straw Hats' allies?"

"Don't be ridiculous."

Enel tilted his head, stretching his neck as if shaking off boredom. "I'm just here to ask you something."

Moria frowned. "What is it?"

Enel's gaze turned icy as he stared at both Moria and the towering form of Oars.

"Between Ron and that oversized toy of yours… who's stronger?"

Moria was momentarily stunned.

The Straw Hat crew, battered and sprawled across the battlefield, were also taken aback.

"Of course… I am stronger! Gomu Gomu no…"

The mindless Oars, infused with Luffy's shadow, raised a massive fist and hurled it toward Enel in a devastating punch.

"Gatling!"

The enormous fists crashed into Enel's body—only for his form to shatter into countless streaks of lightning, dispersing into the air.

In the next instant, his figure reassembled on the other side, completely unharmed.

"This level of power… and you think you can compare to that guy?"

Enel's cold, indifferent gaze locked onto Oars and the startled Moria within.

"A Logia-type…!"

Moria's forehead glistened with cold sweat as an unsettling feeling crept over him.

"The price for mocking a god…"

Enel raised a hand, electric currents crackling wildly around him.

"…is annihilation."

"Sixty million volts…"

A massive surge of lightning converged, forming a draconic shape.

"Thunder Dragon!"
