People are sailing and synthesize the devil fruit of phantom beast sp

"Oh my God, what's happening to me?!"

After An consumed all the crystals, she could feel an overwhelming surge of power erupting from within her body. She stared at her hands in utter disbelief, unable to comprehend what was unfolding.

"Move around a bit," Kairos Flint said casually, pulling out a finely crafted blade from his storage space—one left over from previous syntheses. "And here, take this knife."

An held the weapon with hesitation. She was a singer, not a warrior. She had never held a blade with the intent to harm someone. But the moment the knife rested in her hand, something changed.

Within seconds—less than seven—an intense familiarity washed over her. It was as though the blade wasn't just in her hand—it had become part of her.

"Attack me," Kairos said with a smile.

"W-What?" An stammered. "No, absolutely not! How could I possibly attack you, Lord Kairos?"

Startled, she dropped the knife.

Kairos gave a soft chuckle at her reaction. But his amusement vanished in an instant. A wave of Haki surged from him—dense, suffocating, laced with killing intent.

In a flash, the third-generation Ghost Tetsu sword appeared in his hand, and he lunged forward, stabbing out with speed and precision.

"Ah!"

An's instincts screamed. Every hair on her body stood on end. Her mind blanked under the crushing fear, but her body responded.

Just before the blade could strike, she instinctively activated Shave, one of the Navy's Six Powers. Her body blurred, and with a whoosh, she vanished.

"Ah! What just happened?!"

She reappeared on the bridge in the blink of an eye, stunned by the sudden relocation. The entire movement had happened so fast it felt unreal. She'd moved like a superhuman.

Meanwhile, Vivi sat at the side, already munching on snacks. Nami, Robin, and the others watched from a corner, eyes wide.

"What is Captain Kairos doing now? Why is he attacking her?" Nami frowned.

Robin, more composed, said calmly, "He's pushing An to adapt to her new strength. This is training. Nothing more."

"That makes sense," Nami and Uta nodded in agreement.

Having consumed so many ability crystals, An's strength had soared—now rivaling that of a Vice Admiral.

Kairos's first strike had forced her to react with Shave. But he didn't stop there. He charged again, slashing his blade with renewed force.

"W-Wait, Lord Kairos, please!" An shouted, overwhelmed. She barely had time to think, but she remembered the feeling from before.

Relying on it, she used Geppo—Sky Walk. In an instant, her form blurred again as she disappeared from her spot.

However, she hadn't accounted for her balance this time.

Splash!

She misstepped—and fell right into the sea.

"Ah! Help! I can't swim!"

An flailed mid-air before plummeting. But just before hitting the water, the muscle memory of the Moon Step technique kicked in, and she paused—suspended in the air.

"W-What… is going on?" she whispered, staring at her floating form in awe.

"Good," Kairos said, smiling. He picked up the previously dropped blade with a flick of his foot and kicked it into the air toward her.

An instinctively reached out and caught the spinning blade mid-air.

"Don't let me down," Kairos called out.

And then, he launched himself toward her, blade-first, his body flowing like a sword in motion.

Realizing this wasn't a joke, An's nerves settled. Her mind focused. She clenched her blade and met him in mid-air.

In a flurry of sparks and flashes, their blades collided. Sword against sword. She moved with grace, her style elegant and fluid—like a dancer among petals. Despite her lack of combat background, her perfect-level swordsmanship crystal made her strikes remarkably refined.

But then Kairos used 30% of his true power—one clean, ferocious slash.

The sheer force in his attack was undeniable.

Desperate, An remembered her Devil Fruit power.

With a slap of her palm, she called upon the Phantom Fruit.

And summoned none other than Gol D. Roger, the Pirate King.

Roger's hoarse voice echoed, "Well done. Witness the power of my sword."

A sword materialized in Roger's hand.

This time, even Kairos's eyes widened. Roger looked… real.

No longer a hazy illusion—his body now seemed tangible, nearly indistinguishable from a living person. Even the aura he exuded radiated power. He wasn't just a memory anymore.

This… this was the real deal.

Kairos was thrilled.

A perfect Roger—solid and deadly—meant something incredible. He could record it. Capture images. Use this illusion to his advantage.

But he underestimated what An had created.

As the third-generation Ghost Tetsu clashed with Roger's sword, Kairos felt it.

Contact. Real, electric feedback.

The blades didn't pass through each other. They collided with force, generating friction and a jolt of energy.

"No way… it's real?" Kairos muttered, stunned.

He stared at the sparks flying from their swords, dumbfounded.

Behind him, An gasped, covering her mouth. "I… I summoned him. But he's actually fighting back?"

"Oh my God… is this the true power of my Devil Fruit?"

She landed beside Vivi, dazed.

Everyone on the deck stared up at Roger, still hovering mid-air.

"This is amazing," Kairos grinned. "An, control him. Make him fight me."

His excitement couldn't be hidden. "Gol D. Roger… we're about to turn the world upside down."

His plan—his grand design—had just found its greatest weapon.

"Y-Yes, alright!" An replied, determined.

She too wanted to see just how far Roger could go.
