Is this your trump card?

After revealing Kozuki Sukiyaki's deepest secrets, Nicholas discarded him like trash, deeming him worthless. Neither Ashina Isshin nor the Kozuki retainers reacted much. For Ashina Isshin, Kozuki Sukiyaki had been irrelevant since their decision to exile the Kozuki family. Sukiyaki's survival after the coup only garnered disdain.

The retainers had mixed feelings. Although Sukiyaki was indirectly responsible for the coup and had hidden himself instead of confronting Orochi, he was still the father of Oden and the grandfather of Momonosuke. However, with Momonosuke as the new Shogun, Sukiyaki's sudden reappearance complicated matters.

"Cat Viper, Dogstorm, protect me! It's coming!" Momonosuke suddenly exclaimed, unable to hide his excitement.

"What's coming? Hey, old dog, did you hear that sound?" Cat Viper, initially puzzled, felt a sense of familiarity.

"Old cat!" Dogstorm, ever the loyal guard, immediately used his remaining arm to shield Momonosuke, sensing the moisture in the air.

"Keerii!" An eagle's cry echoed from above, filled with urgency. The strong fighters turned their gazes skyward to see a vast body of water appearing and descending towards the battlefield.

Faces turned pale as the realization set in. The falling "ocean" threatened everyone, even the Nicholas Pirates, as water is a Devil Fruit user's worst nightmare. The sheer volume of water meant certain doom for any ability user caught in it.

Moments earlier, Momonosuke had devised this plan, using Zunesha to unleash a massive water attack. His goal was to ensure Nicholas and his crew suffered, regardless of collateral damage.

"Hey, this must be a joke," Cat Viper muttered, his fur standing on end. As a cat, he despised water.

"Old cat!" Dogstorm yelled, understanding Momonosuke's intentions. Seeing the massive "ocean" above, he grabbed Cat Viper, both shielding Momonosuke.

Izou, Kiku, and Denjiro protected Toki, bracing for the imminent impact. Faced with the overwhelming force of the "ocean," they felt insignificantly small, awaiting their fate.

Meanwhile, the rebel army of Hakumai was in chaos. In the face of such a natural disaster, their strength was insignificant, and many would surely perish upon impact.

Nicholas, instead of fleeing with his Rumble-Rumble Fruit powers, spread his arms towards the descending "ocean," as if to embrace the entire sky.

Creak!

It was as if a tightly strung chord had suddenly snapped. Amidst the thunderous roar of the descending seawater, an invisible force field materialized, suspending the massive 'ocean' in mid-air. This surreal sight left everyone stunned—the deluge that seemed poised to engulf everything was now floating motionlessly above.

If not for the fact that the 'ocean' continued to sway, teeming with countless sea creatures, and the palpable increase in air moisture, the onlookers might have thought they were hallucinating. Nicholas, however, appeared flushed and strained, clearly exerting immense effort.

The Rumble-Rumble Fruit was inherently a powerful Devil Fruit, and after years of development, Nicholas had nearly fused with it, pushing its abilities to extraordinary levels. His unique understanding and application of its powers allowed him to achieve feats akin to other fruits' capabilities. The idea of moving mountains and filling seas was no mere dream for him.

With a sudden twist of his palm, Nicholas directed the massive body of water, weighing billions of tons, away from the battlefield. The redirected seawater cascaded towards another area, causing a significant flood in Kuri. The roaring floodwaters surged like a stampede, inundating the surroundings.

Rumbling...

Towns were submerged, and the beautiful, tall buildings crumbled under the force of the water. Ordinary people struggled to stay afloat amidst the torrent. However, the flood receded as swiftly as it had come, leaving behind devastation and debris.

"Everyone, be careful!"

The crew members stationed on the Moby Dick, moored at the harbor, were momentarily unsteady from the incoming waves but quickly regained their footing and issued commands. Although the turbulent waters weren't enough to capsize the ship, the debris carried by the water posed a risk to the hull.

Marco, in his phoenix form, flapped his wings, observing Nicholas's incredible feat with awe. "No matter when you see it, Nicholas always manages to be awe-inspiring," he remarked. Devil Fruit abilities, in the hands of certain individuals, could perform wonders and achieve miracles.

The question of whether someone who became a sea emperor through an already rare and powerful fruit was truly strong remained. Often, it was the fruit's power that elevated them beyond their natural capabilities. Conversely, those who harnessed less formidable fruits to their utmost potential were undeniably strong, their strength lying in their combat strategy and intelligence.

People like Doflamingo could turn any fruit's ability into something remarkable, excluding the inherently limited regular Zoan fruits.

Nicholas and Whitebeard were examples of immensely powerful individuals who, combined with potent fruits, stood at the world's pinnacle.

"Phew, that was quite strenuous. So, this is your trump card?" Nicholas remarked, looking towards the sea outside Wano. The silhouette of a colossal elephant was now visible—Zunesha had arrived!
