One Piece: With Sign-in System

Ron tailored the breathing techniques to suit the unique traits of each member of his crew.

For Kuina, who pursued explosive strength and peak performance, he chose the Thunder Breathing Technique.

Conis, with her gentle and tranquil demeanor, was taught the Water Breathing Technique.

Bonney, whose Devil Fruit abilities required close contact with her opponents, benefited most from agility and speed. Thus, the Insect Breathing Technique was perfect for her. Robin, sharing similar needs for speed and precision, also began training in the same technique.

Lastly, Enzo, with its fiery personality and natural enthusiasm for battle, was taught the Flame Breathing Technique.

Ron didn't stop there. For Kuina, a fellow swordswoman, he imparted a companion sword style that harmonized with the Thunder Breathing Technique.

This sword technique comprised only a single move, but when mastered to its pinnacle, it was the most powerful strike in the Thunder Breathing arsenal. Focused and unparalleled, it culminated in the move known as Lightning Flash!

In the days following Kuina's mastery of the Thunder Breathing Technique, the Traveler often resonated with the sharp, tearing sound of air being split. A golden bolt of lightning would streak from the ship's bow to its stern, leaving behind a lingering arc of sword energy that shimmered like an electric afterimage in the sky.

While the crew immersed themselves in honing their breathing techniques to enhance their abilities, Ron was far from idle.

Through daily experimentation, his understanding of the Float-Float Fruit grew sharper, and his control over it steadily approached the legendary prowess of the Golden Lion himself.

His abilities now encompassed feats like pulling small islands into the sky, lifting large sections of earth, condensing seawater, and manipulating cloud formations with ease. The potential for large-scale attacks using this power was staggering.

As he continued to refine his control, Ron's thoughts wandered to Fujitora and the powers of the Gravity-Gravity Fruit.

"If Fujitora can generate gravitational waves to create a force of repulsion capable of pushing everything away, then can the Float-Float Fruit, which manipulates gravity to make objects float, achieve something similar?"

With this question in mind, Ron conducted numerous experiments, only to discover a crucial limitation: the Float-Float Fruit couldn't manipulate gravity itself.

Its power was confined to freeing inanimate objects from the pull of gravity, allowing them to float under the user's control. Its strength lay in precise manipulation, not in altering gravity's magnitude or direction.

The Gravity-Gravity Fruit, on the other hand, excelled at adjusting the intensity and direction of gravity but lacked the Float-Float Fruit's finesse in direct control.

The two fruits shared similarities but differed significantly in their applications.

In terms of raw ability, the Gravity-Gravity Fruit appeared superior. Its capabilities included horizontal gravity, zero gravity, anti-gravity, pressure, pull, repulsion, and even gravitational waves.

However, the outcome of a confrontation between the two fruits would likely depend on the strength and ingenuity of the users.

Ron couldn't help but anticipate the day he would cross paths with Fujitora.

"Will his gravity pull me down, or will my Float-Float abilities render his gravity meaningless?"

With the knowledge that his powers couldn't directly manipulate gravity, Ron shifted the development of his Float-Float Fruit abilities in a new direction.

He began exploring ways to unleash devastating techniques by stripping objects of gravity.

Beyond simple attacks like hurling massive mountains or torrents of seawater from above, Ron pondered new and more creative applications for his powers.

As he delved into these possibilities, Ron didn't neglect his training in physical strength, swordsmanship, and Haki.

Akainu's Great Eruption attack, though ultimately blocked, had left him struggling. If faced with another strike of similar magnitude, he wasn't confident he could withstand it.

While Aokiji could battle Akainu for ten days, and Kizaru likely stood on equal footing with them, Ron realized he had yet to reach the level of a Marine Admiral or the combatants who clashed at Marineford.

And beyond the Admirals loomed even greater threats: the Five Elders, whose strength was shrouded in mystery, and Imu, the enigmatic figure at the pinnacle of power.

Having positioned himself as their adversary, Ron didn't entertain the hope of a protagonist's halo or last-minute rescue. He understood that his survival and success depended solely on one thing—his own strength.

True strength is the ultimate safeguard!

With this realization, Ron set his sights firmly on the future. In six months, he would venture into the Grand Line and New World, hoping to utilize the system's rewards to rapidly grow stronger. His goal was clear: to achieve the might of an Admiral—or even a Yonko—as quickly as possible.

Because if the Marines decided to send someone as tricky as Kizaru after him, things would get...complicated. Staying perpetually airborne was not a viable solution.

As Ron pondered his next move, elsewhere in the North Blue, the Marines Admiral, wielder of the Glint-Glint Fruit, Kizaru had already been dispatched by Fleet Admiral Sengoku.

Now stationed at a North Blue Marine branch, Kizaru was awaiting any news of the elusive floating ship.

The moment he received word of the vessel's whereabouts, he would take action immediately.

The World Government and the Marines had tolerated the Golden Lion in his decline, a shadow of his former self. But they could not afford to let someone as young and talented as Ron rise unchecked.

Who knew how far this youth could ascend?

The thought of another Whitebeard, in his prime and only in his twenties, was enough to rob the Five Elders of sleep.

Thus, Kizaru had been urgently recalled from the New World, where he'd been managing affairs, and sent directly to the North Blue. With his ability to move at light speed and use photon manipulation for short bursts of flight, Kizaru was the ideal candidate for this mission.

Ron, the Traveler, had to be dealt with—before he became an unstoppable force.

For five days, Kizaru had waited in the North Blue, yet there had been no sign of the floating ship.

"Are we sure he's still in the North Blue?"

Sentomaru, hefting his massive battle axe, glanced at Kizaru and asked gruffly, "Old man, are we just going to sit here twiddling our thumbs until he decides to show up?"

"Who knows, really?"

Wearing his signature yellow-striped suit, the Justice cape draped over his shoulders, Kizaru lounged in a chair, legs crossed, lazily picking at his fingernails.

"Maybe he's already left the North Blue. Didn't he mention heading to the Grand Line? Couldn't he be there by now?" Sentomaru frowned.

"The headquarters hasn't heard anything yet either," Kizaru replied nonchalantly, still fiddling with his nails. "That kid's pretty clever, you know. Maybe he guessed I'd be coming and decided to lie low…"

"That's…a possibility," Sentomaru admitted with a grim nod. "But if that's the case, this is going to be tricky."

"Very tricky indeed," Kizaru said, nodding sagely. "The World Government and the Marines have really stirred up a hornet's nest this time, haven't they? That young man, the Traveler Ron…"

Sentomaru's curiosity got the better of him. "You talk like you know this Ron guy pretty well. Are you familiar with him?"

"Not really," Kizaru said with a wave of his hand. "We've only met a few times. But…"

He tilted his head back, sunlight glinting off his sunglasses, and recalled the dark-haired youth he'd seen aboard that ship.

That boy had looked at him with unwavering confidence, an unshakable belief that one day, he would surpass Kizaru's strength.

And in those eyes, Kizaru had seen something rare—a resolute certainty in his own future that Kizaru had never encountered before.

"Not too familiar," Kizaru murmured, standing up and gazing at the sky, hands buried in his pockets. "But I know one thing for sure."

Sentomaru's expression grew serious. "What's that?"

Kizaru's next words sent a chill down Sentomaru's spine, his eyes widening in shock.

"That kid… is a terrifying monster through and through. If I had a choice, I'd rather not face him as an enemy."
