One Piece: With Sign-in System

It was almost impossible to believe that the devastation before their eyes was the result of a battle between just two people.

The sheer terror of the scene!

Hundreds of marines floating on the sea's surface were paralyzed with fear.

On the distant Heart Pirates ship, Bepo and Shachi collapsed weak-kneed onto the deck, their legs trembling uncontrollably. Even Law couldn't help but let a few drops of cold sweat trickle down his face.

"That guy... is he really fighting a Marine Admiral?"

High in the sky, Traveler floated several kilometers above the ocean. Ron's right hand, clutching the black blade Shusui, trembled slightly, his mouth bleeding. Suspended in mid-air a hundred meters above the sea, he looked down at Akainu, who stood atop a thick slab of solidified magma. A faint smile tugged at Ron's lips.

"Looks like you won't be killing me today. Let's meet again, somewhere on the Grand Line or the New World."

With that, he casually swung his sword, sending several slashes slicing through the air toward the ocean below.

Before the eyes of the marines floating on the sea, and even the distant Heart Pirates, a massive rectangular block of water, thousands of meters long, a hundred meters wide, and equally tall, rose from the ocean like an enormous brick of liquid. It was as if the sea itself had been carved out.

"!!"

The marines on the water stared in shock, their gazes fixed on the towering block of water overhead. They were stunned, speechless, their expressions frozen in disbelief.

It was as if the heavens and the sea had been inverted.

"Separated from the ocean, seawater is nothing but ordinary water. Do you think something like this can harm me?" Akainu's cold gaze swept over the massive block of water suspended above him. His right half had completely transformed into molten magma.

"Who knows?"

Ron, his face slightly pale, smirked faintly. He lowered his finger with a casual gesture.

The colossal water block seemed to lose some invisible force that had been holding it together. With a deafening crash, it collapsed, millions of tons of seawater cascading downward with unstoppable momentum, engulfing the marines below in utter panic.

"Great Eruption!"

Akainu unleashed a magma fist, even more powerful than his previous attack, aiming to counter the massive onslaught of water.

Meanwhile, Garp delivered a thunderous punch, and Gion unsheathed her blade, slashing upward with a sword strike that extended for a kilometer.

Akainu struck back in defiance, while Garp and Gion worked to shield the weaker marines from the overwhelming attack's impact.

Even as the seawater was shattered and fragmented by their combined attacks, the sheer force of it crashing down onto the sea still sent towering waves surging outward.

The Heart Pirates, though far away, weren't spared. Their ship rocked violently amidst the colossal waves.

"This... this is my parting gift."

Ron's voice carried over the chaos, calm yet filled with a sharp edge. Floating a hundred meters above the sea, he cradled the young female swordsman who had attacked the warship earlier. His tone was mocking as he addressed Akainu, Garp, and the others below.

"Do me a favor. Tell the World Government and the Marines this: If they insist on branding this free traveler as a criminal, I'll gladly live up to the title."

He glanced at the sea below, his eyes briefly meeting Garp and Gion's, as well as Hina, who was leaning weakly against Gion for support. His smile deepened.

"Let's meet again on the Grand Line."

With those parting words, Ron ascended rapidly into the sky. Within moments, he disappeared from everyone's sight, leaving behind a ravaged battlefield and a fleet of marines grappling with the devastation.

Garp and Gion stood in silence, their expressions complicated.

Hina, her strength sapped after being exposed to seawater, could only lean against Gion. Despite her weakened state, she had heard and seen everything. A faint smile graced her lips.

"This... this is fine..."

Meanwhile, Akainu stood atop his magma, his face ashen. His fists clenched tightly within his gloves, his killing intent palpable, eyes dark as night. A seething anger boiled within him as he spat two words through gritted teeth:

"That Bastard!"

…

High above the clouds, The Traveler glided through the sky like a celestial ship, surrounded by endless seas of mist.

Conis, Robin, and Bonney sat aboard, their expressions still tinged with disbelief. Although Ron had explained his intentions earlier, escaping from both Garp and Akainu alive and now sailing freely through the skies felt almost surreal.

"Does this mean," Bonney asked excitedly, "that with Captain's Float-Float Fruit powers, we can now go anywhere we want across the entire ocean? No more worrying about Marine blockades?"

"As long as we don't encounter any Devil Fruit users with flight abilities, that's correct," Robin said softly, nodding.

Overwhelmed with joy, Bonney hugged the little cloud fox Su in excitement. "Captain is incredible! I knew joining this ship was the best decision ever!"

Robin chuckled lightly, but Conis noticed her hands trembling as she raised her teacup.

So even Robin wasn't as calm as she appeared...

Of course, Robin couldn't remain calm. After all, Ron had deliberately sought out both Garp and Akainu—two of the most powerful figures on the seas—and not only survived but escaped unscathed.

Who in their right mind would attempt such a thing? Even the most insane pirates wouldn't dare challenge such odds.

But Ron not only dared—he succeeded.

And in the process, he destroyed six Marine warships.

It was as if he had slapped both the Marines and the World Government across the face.

"This incident is going to increase the Captain's bounty again for sure! That's great news… I wonder if I'll finally get a bounty too after this," said Bonney, her face lighting up with anticipation. She snuggled against the soft, fluffy fur of Su, as if seeking comfort from her own excitement.

"A bounty?!" Enzo's eyes sparkled with enthusiasm, his small tail wagging rapidly. "I've heard about that from Sister Robin before! It's the thing that represents how strong someone is, right?"

"Will I get one too?!"

"Probably not," Conis replied from where she leaned on the railing, gazing out at the vast sea of clouds before them. Her golden hair swayed gently in the breeze, framing her innocent, angelic face like she belonged in the heavens themselves. "After all, we're not as famous as the Captain or Robin."

"That's true," Bonney admitted with a sigh, her excitement deflating. Enzo's hopeful eyes dimmed slightly, and his tail slowed its wagging.

While they were chatting away on the ship…

In the sky, Ron flew steadily toward the floating Traveler Ship. He held Kuina securely in his arms in a classic bridal carry.

"Hold still, we're almost there," Ron said, his tone reassuring.

Kuina blushed faintly, her proud and composed demeanor shaken. Her delicate face showed traces of embarrassment, and she shrank slightly in his arms.

"Why... why are you carrying me like this?!"

"Haha, don't overthink it," Ron laughed, clearly enjoying her reaction.

"How could I not think about it! You're doing this on purpose, aren't you?!" Kuina puffed out her cheeks, her voice rising indignantly as she reached up to pinch his cheeks.

Ron let her tug at his face without resistance, his bright smile never fading. "It's been so long, Kuina. I didn't expect to see you here today. Did you come because you heard the news?"

Her hands paused. Looking into his earnest eyes, Kuina released his cheeks and nodded lightly. "Yes, I followed the trail of the Marines' ships."

"Thank you," Ron said, his voice filled with genuine gratitude.

"It's been six years," he continued with a gentle smile. "You've grown from that tomboyish kid into a beautiful girl."

Kuina's face turned crimson. She quickly crossed her arms and glared at him. "Your focus is entirely misplaced!"

"Uh… I didn't mean it like that—"

"Idiot!" Kuina's hand shot to her sword, its hilt thumping against Ron's head.

"Ow!" Ron cried out dramatically, making Kuina roll her eyes despite her lingering blush.

When they finally landed aboard the Traveler, the three women on deck—Robin, Conis, and Bonney—stared in surprise.

"Who's this?" Conis asked curiously.

"This," Ron said proudly, "is the first mate of this ship, Kuina."

Standing beside him, Kuina glanced at the three women with an air of calm authority. She then turned her sharp gaze to Ron, her voice tinged with subtle sarcasm. "I didn't expect all your crewmates to be such beauties, Ron..."

Ron scratched the back of his head awkwardly, offering a sheepish grin.

Once they introduced themselves, Robin, Conis, Bonney, and Enzo quickly warmed up to Kuina. They learned about her daring attack on the Marines ships to protect Ron, despite the overwhelming odds.

Their admiration for her grew immensely. The initial wariness they had toward this new companion melted away, replaced by respect and genuine camaraderie.

"To confront the Marines head-on in that situation… to fight them for Ron's sake... Just how much courage and determination does that take?"

Robin, Conis, and Bonney exchanged meaningful glances. In Kuina, they saw the kind of loyalty and strength that justified Ron's constant mentions of her. She wasn't just the first mate—she was the one he trusted wholeheartedly, the one who had stood by him in the face of impossible odds.

This was Kuina, the legendary first mate of the Traveler.

At this moment, the three women silently acknowledged Kuina's role as the first mate in their hearts.

…

By dusk, the Traveler drifted aimlessly through the cloud sea, its silhouette like a small boat amidst the vibrant hues of the setting sun.

"When I left Foosha Village, I spent some time traveling across the East Blue before eventually joining a pirate crew heading for the Grand Line…"

Ron and Kuina sat across from each other at a small table on the deck, recounting the events of their lives over the six years they had been apart.

Before them, the glasses held a special fruit wine—a gift from Makino when Ron left Foosha Village. He had been saving it all these years, waiting for the perfect occasion. Today, with Kuina here, seemed like the right moment to finally open it.

In the kitchen, Conis busied herself preparing dinner, with Robin and Bonney lending her a hand. Tonight, they were hosting a grand feast to welcome Kuina aboard properly. The aroma of delicious dishes wafted across the ship, creating a warm and inviting atmosphere.

Meanwhile, Enzo had retreated to the gravity training room. Witnessing the clash between Ron and Garp earlier had only deepened his awareness of his own weakness.

In truth, Enzo wasn't weak by any means. Having mastered the Hasshoken, several other martial arts styles, as well as the techniques: Shave and Tempest Kick, and even wielding Armament Haki, he was already a formidable force on the seas. But compared to the monsters around him—Ron and the other extraordinary figures he encountered—his strength felt insufficient.

Elsewhere on the ship, Su lounged contentedly beneath the tree on the grassy deck, its fluffy tail curled around itself as it dozed peacefully.

The entire ship exuded an air of harmony and warmth, a haven in the vast sky.

Yet, while tranquility reigned aboard the Traveler, the oceans below were anything but calm.

Somewhere far away, the waves surged violently, roaring with unstoppable ferocity as though heralding the arrival of another storm. The sea's fury was a stark contrast to the serene floating ship, a silent reminder that the world beyond their sanctuary was always teetering on chaos.
