One Piece: sign-in to Ryujin Jakka

With Big Mom's Might Nation (Ikoku)and Roman's Day Tiger (Hirudora) colliding—

A thunderous explosion roared into everyone's ears!

BOOM!!!

The entire land trembled and quaked as if the heavens were collapsing.

RUMBLE!!!

The ground cracked and wailed under the impact, shrieking skyward in agony!

A wild storm swept across the skies, darkening the clouds even more. Everyone watching the scene had sheer terror written across their faces.

As the ground continued to quake and roots rampaged, Katakuri fell into despair.

"This guy... he's just..."

"Too strong!!!"

"But, weirdly enough... kind of cool!!!"

Brûlée couldn't help but blurt out her thoughts aloud.

Instantly, all the Charlotte Family members around her turned to stare.

Brûlée quickly switched to her darker personality, snarling, "Only by destroying that face with my own hands will Mama feel at peace!"

"Enough talking! Get over here and help! We must protect all the VIP guests—understood?!"

"Yes, understood, Brother!"

But before any of them could act, Roman had already closed the distance to Big Mom. With a voice like a demon's whisper, he leaned in and murmured into her ear.

"BIG MOM… out of pity, I'll tell you where the nun is."

A wicked grin curled beneath the hood of Roman's cloak.

Before Big Mom could react, Roman spoke again, his voice low and cold, heard only by her:

"The nun has always been with you... She's inside your belly. You ate her."

"WHAT!!!?"

Big Mom's mind was thrown into utter chaos!

But that wasn't all.

Roman continued: "And not just the nun. Even your former companions—you devoured them too." His words were like the sharpest blade—Mercilessly stabbing into Big Mom's greatest weakness!

"No! No! You're lying! You're lying!!!"

Big Mom's eyes filled with confusion and madness.

She refused to believe it, yet her subconscious told her Roman was telling the truth.

In an instant, she was mentally pulled back to the day she had been separated from the nun and her friends...In that daze, she exposed her fatal weakness!

The so-called Iron Balloon, known as BIG MOM… when thrown into a berserk rage, her defense drastically dropped.

To Roman, this was the perfect moment for a one-hit kill!

That's exactly what Roman wanted. He had no intention of dragging this fight out for three days and nights! It would waste too much energy—And more importantly, the longer it dragged on, the more unpredictable things could become.

Roman couldn't guarantee whether her old flame, Kaido, would rush over after hearing the news... Or if Shanks, in his desire to maintain balance across the seas and uphold the Four Emperors' structure, might intervene.

Either way, Roman wanted no part in it.

So, as Big Mom exposed her fatal weakness…

Roman softly whispered:

"All Things in the Universe, Turn to Ashes—Ryūjin Jakka!

At that moment, an inferno rose into the heavens!

A raging blaze, like a flowing river, surged skyward. In the blink of an eye, flames flashed like lightning, spreading across the entire sky!

No more dark clouds. No more thunder. No more wind or rain.

Only an overwhelming sea of fire blanketed the sky.

Ace stood stunned at the sight.

He also wielded fire—But this fire… sent an unprecedented chill down his spine.

This wasn't the Heavenly Fire that Big Mom had used before. It felt more like a superior flame suppressing a lesser one, just like the natural dominance between Devil Fruits.

"Amazing... this is just too amazing!!"

Stars practically twinkled in Ace's eyes. His gaze toward Roman brimmed with a hard-to-describe awe.

It was the reverence only a fellow flame-wielder could feel. To manipulate fire to such a transcendent degree, Ace was overwhelmed with respect!

The flames swirled back into Roman's blade, Ryūjin Jakka.

The fire engulfing the sword emitted a chilling aura—So cold it was as if they were thrown into an ice cellar. It pierced into their bones. Breeding a new kind of fear in their hearts…

The fear of "Zero."

Stussy turned to Morgans with a sly smile.

"Looks like I win this time."

Just like Ace, her eyes sparkled with a light only they could understand.

As if to validate her words, Roman suddenly moved in midair.

Opening the Eight Inner Gates, gripping Ryūjin Jakka, he dove like lightning from the sky.

A line of fire etched itself in the air. It was like a scar across the heavens. When they looked again, Roman was already behind Big Mom, and he slowly began to sheath his blade.

In a voice only he could hear, he murmured:

"Now… we can proceed to the next phase of the plan."

Far away, Phantom Illusion, Howard East, took out a golden Den Den Mushi.

Without hesitation, he pressed the button.

"Buster Call—initiated!!!"

At the same time, Roman's slash burst forth with all its might! A brilliant arc of flame exploded. The blinding brilliance consumed everyone's vision.

Big Mom's arm, her abdomen, her waist—all severed along a clean diagonal line.

Blood burst forth like a geyser!

The sight left many of Charlotte's children collapsing to their knees.

"No way! That's impossible!"

"Mama... can't be defeated like this!"

"This can't be real—I don't believe it!!!"

"That slash… it's beyond terrifying. It's monstrous!"

"From this day forward, the name BIG MOM will fade—And the legend of 'Zero' will rise!"

Everyone attending this tea party…Felt the terror of that strike.

Unmatched power. Unmatched speed. Unmatched control.

All at the highest level!

And just as the entire venue was frozen in shock, a massive barrage of cannon fire rang out in their ears!

"What's going on?"

"What's that cannon fire?!"

"Report to Lord Katakuri! I-It's the Marines! The Marines are here!!!"

Katakuri froze at the report, but quickly snapped back.

"Brûlée!!!"

"I'm here, Brother!"

"Open the Mirro-World—We're retreating now!!!"
