Rimuru and Ultima Goes To One Piece (Rimuru and Ultima x One Piece)

Chapter 21: The March Toward Whitebeard

The roar of battle echoed through Marineford as the clash between Whitebeard's forces and the Marines raged on. The sky seemed to crack under the immense power radiating from the combatants below. Whitebeard's fleet had made their entrance, and chaos erupted as both sides engaged in a deadly struggle for dominance.

Rimuru and Ultima sat in their positions, watching the mayhem unfold around them. Marines and pirates clashed fiercely, but neither of the two seemed in any hurry to move. Their focus was on one thing—Whitebeard.

"Looks like it's starting," Rimuru said, his eyes narrowing as he spotted Whitebeard on the battlefield. The legendary pirate towered over his surroundings, every step shaking the ground beneath him.

Ultima leaned forward in her seat, her grin widening. "Finally. I was getting bored just sitting here. He's a big one, huh? You think he'll put up a good fight?"

Rimuru smirked. "He didn't earn the title of the 'Strongest Man in the World' for nothing. But we're not here to admire him. We're here to take him down."

The clash between Whitebeard's forces and the Marines intensified. Explosions lit up the sky, and the earth trembled with the force of the attacks. Pirates charged forward, trying to break through the Marine defenses, while the Marines retaliated with all their might. But amidst the chaos, Whitebeard stood calm, observing the battlefield as if calculating every move.

Ultima stretched lazily and stood up. "Alright, I'm done waiting. Let's have some fun."

Rimuru nodded in agreement. "Yeah, it's time to make our move."

Without another word, the two Shichibukai descended from their perch and stepped onto the battlefield. The moment their feet touched the ground, it was as if a wave of pressure rolled over the nearby combatants. Pirates and Marines alike froze for a brief moment, their attention drawn to Rimuru and Ultima. The sheer aura they exuded was enough to make weaker fighters tremble.

"Is that... Rimuru Tempest and Ultima?" a Marine whispered, his face pale with fear.

"They're Shichibukai, aren't they? What are they doing here?" another pirate muttered, stepping back cautiously.

Ultima cracked her knuckles, her eyes gleaming with excitement. "Let's see how many we can crush before we get to Whitebeard."

With that, she vanished from her spot, moving at a speed that left only a blur in her wake. In the blink of an eye, she appeared in front of a group of pirates, her fist already swinging. The moment her fist connected with the nearest pirate, there was a loud crack, and his body was sent flying across the battlefield, smashing through several others in the process.

"One down," Ultima said, chuckling.

Rimuru followed suit, his movements equally swift. He didn't even bother drawing his sword; his fists were more than enough to deal with the enemies in his path. As pirates charged at him, he weaved through their attacks with ease, landing devastating blows that knocked them unconscious or worse. Each strike was calculated, each movement precise. Rimuru wasn't just fighting—he was dismantling his opponents.

"They're like insects," Rimuru commented, sidestepping a clumsy attack from a pirate before delivering a powerful punch to the man's stomach. The pirate crumpled to the ground, gasping for breath.

"Insects against lions," Ultima added, her voice full of amusement. She twisted mid-air, delivering a devastating kick to another pirate's head, sending him crashing into the ground.

As they continued cutting down anyone in their path, they kept their eyes on the true prize—Whitebeard. He was still at the center of the battlefield, and though the pirates around him were trying to push forward, Rimuru and Ultima were making their way toward him, leaving a trail of bodies in their wake.
