****************

Sasuke had been observing Fujitora for some time. Ever since he gathered intelligence about the enigmatic Admiral, an intense desire had stirred within him. Testing his abilities against Fujitora promised more than just a thrilling challenge—it was an opportunity to explore the uncharted depths of his own power.

Sasuke's Six Tomoe Rinnegan granted him unparalleled control over force fields, a skill that seemed to harmonize intriguingly with Fujitora's gravity-based techniques.

Beyond that, the blind swordsman was reputed to be one of the world's finest blade masters. The thought of matching his Rinnegan-enhanced swordsmanship against Fujitora's gravity-wielding expertise was irresistible to Sasuke. Perhaps through this battle, he could discover a way to merge the Rinnegan's might seamlessly with the art of the sword.

Fujitora, sensing Sasuke's intent, lifted his head slightly. Despite the tense atmosphere, his expression remained calm, even amiable. "Uchiha Sasuke," he began, his tone even and measured, "don't be hasty. There is no—"

Sasuke didn't wait for him to finish. His crimson eyes narrowed with focused intent. "Shinra Tensei!"

The surge of repulsive force rippled outward, sending Fujitora hurtling backward like a leaf caught in a hurricane. Dust and debris scattered in every direction as the ground quaked under the impact. Sasuke wasted no time, leaping into the air with his Kusanagi sword gleaming ominously. His blade descended in a deadly arc toward the Admiral.

For a moment, Fujitora appeared caught off guard, but his composure returned in an instant. With deliberate movements, he unsheathed his sword from its scabbard, raising it to meet Sasuke's strike. Their blades collided, and the clash produced a resounding shockwave that tore through the battlefield, forcing everyone nearby to brace themselves.

The Straw Hat crew, watching from a safe distance, stood frozen in shock.

Zoro's eyes widened as he watched the intensity of the duel. He instinctively placed a hand on his own swords, itching to jump in but aware of the gulf between their power levels.

Sanji's cigarette slipped from his lips, falling to the ground unnoticed.

"That blind guy… He's a Marine Admiral candidate? Seriously?" he muttered, unable to mask his disbelief.

An Admiral candidate may not carry the same weight as a full Admiral, but his strength was undoubtedly extraordinary.

"But he's blind… How?" Sanji muttered in disbelief.

The two combatants moved their battle further and further away, their figures becoming distant blurs amidst the continuous sound of colliding blades and bursts of power.

Fujitora, sensing Sasuke's intent to draw the battle away from Sabaody Archipelago, cooperated, silently guiding the fight elsewhere.

Sasuke wasn't worried about Ace.

Kizaru, being an ally, knew who was untouchable and who wasn't.

Meanwhile, Kizaru, who had been lazily observing, felt a spark of mischief after Sasuke's departure.

With Ace standing defiantly before him, Kizaru's cynical grin widened.

"You're not my boss's kid, and I'm certainly not your Uncle Kizaru," he murmured, his tone dripping with mockery.

In a burst of golden light, Kizaru moved faster than Ace could react.

"Yasakani no Magatama!"

Beams of light spread out in multiple directions, refracting off surfaces before converging on Ace.

Kizaru followed this with his signature Light Speed Kick, slamming Ace to the ground in a fiery explosion of smoke and debris.

Ace retaliated with a flurry of Hiken (Fire Fists), but Kizaru's agility and elemental prowess made it impossible to land a hit.

Kizaru countered with precise and relentless strikes using his light sword.

In contrast to Ace, who held back to avoid harming his allies, Kizaru had no such reservations.

His attacks were unyielding, forcing Ace onto the defensive.

As Ace dodged another strike, he was blindsided by Kizaru's Yata no Kagami, sending him sprawling.

Kizaru stood over him, preparing to finish the fight.

"Ace!" Luffy cried out, launching his Gomu Gomu no Gatling, but Kizaru effortlessly dodged each punch, his body shimmering as light.

Just as Kizaru's blade was about to strike, a third figure intervened.

The clash of swords rang out as Kizaru's blade was stopped.

Standing before him was none other than Silvers Rayleigh, the Dark King himself.

"Rayleigh-san!" Ace exclaimed in shock.

Rayleigh smiled warmly.

"Ace, it's been a while."

The Straw Hat crew collectively exhaled in relief.

Even Luffy's older brother couldn't handle Kizaru, but with this newest arrival, their hope was rekindled.

Kizaru, however, seemed more annoyed than intimidated.

"Why can't you old relics of the past just stay retired?"

Rayleigh chuckled.

"These kids are the future. It would be a shame to let you ruin that."

"True, it would be," Kizaru admitted, though his playful tone disappeared.

Raising his light sword high, he warned, "But if you insist on interfering, you'll be taken down with them."

Despite his words, Rayleigh remained steadfast, taking Ace's place and clashing with Kizaru in an intense duel.

While they battled, Bartholomew Kuma, who had been silently observing, finally moved.

In a sudden assault, Kuma incapacitated Ace and used his Nikyu Nikyu no Mi powers to launch the Straw Hats to different locations.

Luffy watched helplessly as his crew and his brother disappeared before his eyes.

Kizaru and Rayleigh, now without a reason to fight, disengaged.

Rayleigh withdrew, taking the injured Ace with him.

Kizaru turned to Sentomaru, who asked, "Should we pursue them?"

Kizaru shook his head. "Our objective isn't the Whitebeard Pirates. Let's not make things more complicated."

He then cast a sidelong glance at Kuma.

"You'll have to explain yourself to Sengoku for this."

Kuma remained calm, clutching his Bible tightly, his gaze lingering in the direction Luffy had flown.

"I will handle it myself."

Back in Marineford, Sengoku's office was in chaos.

The Marine Fleet Admiral roared in frustration; his desk now reduced to splinters.

"Damn that Uchiha Sasuke! Damn Ace!" he bellowed.

"How did they even end up at Sabaody without us knowing?!"

Slamming his fists onto the wreckage of his desk, Sengoku turned his fury toward Garp.

"Garp! You and your whole family are nothing but trouble!"

Gritting his teeth, Sengoku growled, "Tell Kizaru to bring Kuma back immediately!"
