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

A tsunami is a natural disaster that commands awe and fear.

Water, often perceived as one of the gentlest substances in the world, can turn devastating when amassed in sufficient quantity and driven with force.

At its peak, water's destructive power can even bring about the destruction of the world.

Whitebeard, renowned as the man who can destroy the world, embodies a similar force.

His mastery over the [Gura-Gura no Mi] allows him to wield vibrations capable of shattering islands and summoning tsunamis.

However, even he was taken aback by the peculiar skills of his current adversary.

"Gurarara! Impressive!"

As Whitebeard observed the three consecutive tsunamis rising in the distance, each one towering higher than the last, he couldn't help but appreciate Hoshigaki Kisame's capabilities.

"This kind of strength... being a mere Shichibukai feels like an insult, much like that Hawkeye brat."

Sasuke stood nearby, his body encased in the blue skeleton of his [Susanoo], which swiftly expanded into a half-body form, wielding a colossal blade.

"I'll handle it."

Though Sasuke's cold demeanor remained intact, he couldn't hide his shock at Kisame's immense strength.

A tsunami of this magnitude posed little threat to him, but Kisame's rapid progress was unnerving.

In this turbulent sea, it wasn't just Sasuke and his companions growing stronger.

Their rivals were evolving, too—a reality Sasuke now refused to ignore.

Just as Sasuke prepared to cleave the enormous waves with his blade, Whitebeard stepped forward, halting him.

"Stand down, Sasuke! This is my battlefield!"

With a mighty punch, Whitebeard unleashed the power of his [Gura-Gura no Mi], striking the air and fracturing it like glass.

CRACK!

The sound of shattering filled the air as fissures spread rapidly through the atmosphere.

"Retreat to the ships!" Marco shouted, urging the crew to fall back.

The confrontation was too grand for ordinary sailors to survive.

A massive tsunami, equal in scale to Kisame's, surged forward to meet its counterpart.

When the two forces collided, the sea turned into chaos, storms raging, and torrential rain pouring down.

"Gurarara! If you had faced anyone but me, even if it was one of the other Four Emperors, they might have struggled against you!" Whitebeard laughed heartily.

"Hoshigaki Kisame, when it comes to sea combat, I can tell that you are the strongest among the Shichibukai!"

Sasuke couldn't suppress the slight twitch at the corner of his mouth.

Amid the stormy chaos, Kisame emerged, his bloodthirsty grin betraying his excitement.

"This is just the appetizer, Whitebeard. The real surprise comes now."

And he didn't explain anything after that and attacked straight away.

"Water Style: Ten Thousand Sharks Attack!"

Kisame used his palms and pressed them against the water, summoning a swarm of enormous sharks, each over fifteen meters long.

The ocean boiled as the ravenous predators leaped forth, creating pandemonium.

The pirates on Whitebeard's side scrambled to respond, but their disarray left them vulnerable.

Several fell victim to the sharks' ferocious jaws and sustained injuries.

"Damn it! Fight back! Don't just stand there!" Marco roared as he dove from the skies, knocking one of the sharks into the air.

"Fire Fist!"

Ace unleashed a massive flaming punch, incinerating dozens of sharks in an instant.

He shouted to Marco, "Let me and Sasuke handle this—go back to help Pops!"

Whitebeard, seeing one of his sons fall to the sharks, erupted in fury.

Leaping into the fray with his mighty naginata, he charged toward Kisame.

"Boy, for daring to hurt my dear children, you'll pay!"

Unleashing his [Conqueror's Haki], Whitebeard's gaze glowed with a menacing red light as he struck down with electrifying force.

"That's terrifying!" Kisame thought, frozen under the oppressive aura.

At that moment, he instantly knew that he would be hurt badly if he didn't do anything.

'I couldn't deal with this on my own…' he lamented, but it was no time to sulk.

Realizing he couldn't match this blow head-on, Kisame quickly unfurled a scroll given to him by Colt and infused it with chakra.

BOOM!

An immense surge of blue energy erupted from the scroll, forming a colossal, ethereal phantom behind Kisame.

From the distance, Sasuke, who had been dispatching sharks, stopped in his tracks, his eyes wide with disbelief.

"Colt?!"

Sasuke recognized the chakra's signature instantly—it was unmistakably Colt's.

"Didn't expect me so soon, did you, Sasuke?" Colt's voice echoed into the minds of Kisame and Sasuke.

"Colt-sama," Kisame responded inwardly, "I didn't expect to need your aid. Whitebeard's vibration powers completely counter my abilities."

Kisame's frustration was evident, but Colt's tone remained nonchalant.

"You've done well. Leave the rest to me."

The scroll contained a portion of Colt's chakra and consciousness, enough to tip the scales of the battle temporarily.

"Colt, you're not planning to kill Whitebeard, are you?" Sasuke asked, panic creeping into his usually calm voice as he flew toward them.

The conversation was not heard by the others.

"Well, I don't want to kill him particularly" Colt replied lazily.

"But whether he survives or not depends entirely on him."

Colt's voice grew serious.

"One sword Attack. That's all I'll use. Whether he lives or dies is up to fate."

Sasuke paused midair, his grip tightening on his blade.

"Then I'll join his side temporarily. I want to see the results of your power in this world firsthand."
