Isaac Newton in One Piece

Kieran's vision blurred, his body swaying unsteadily. His knees buckled, and he collapsed to the ground, unconscious. His last thoughts were fragmented—fear, confusion, and regret swirling in his mind as darkness overtook him.

"Kieran!" Nolan shouted, dropping to his knees beside him. His hands trembled as he checked for a pulse, relief washing over him when he felt it—weak but steady. However, the danger wasn't over. He glanced up at Miss Monday and Mr. 9, who were slowly advancing, their expressions cold and determined.

Nolan's heart pounded in his chest. He gripped his bow tightly, but his hands were shaking too much to even nock an arrow. "S-stay back!" he stammered, his voice cracking.

Miss Monday cracked her knuckles, her towering frame casting a shadow over him. "You're brave, kid, I'll give you that. But this isn't your fight. Hand him over, and maybe we'll let you walk away."

"I'm not leaving him!" Nolan yelled, though his voice wavered. He felt hopeless. Kieran was down, and he was no match for these bounty hunters. His mind raced for a solution, but nothing came.

Suddenly, a gust of wind rushed past them, and a faint green glow illuminated the area. Before Nolan could process what was happening, Isaac appeared, moving so fast that his figure was almost a blur. His body was surrounded by a faint green aura, his eyes sharp and focused.

"What the—?!" Mr. 9 shouted, startled by the sudden appearance.

Isaac didn't say a word at first. In one swift motion, he scooped up both Nolan and Kieran as if they weighed nothing. Nolan gasped, gripping Isaac tightly as he felt the wind rush past him. Isaac turned his head slightly, a cocky grin spreading across his face as he winked at the bounty hunters.

"Sorry to cut this short," he said, his tone light yet confident, "but we've got places to be."

Before they could react, Isaac pushed off the ground with incredible force, the green aura flaring brighter as he vanished from sight, leaving only a trail of wind and dust in his wake. Miss Monday and Mr. 9 stood frozen, their mouths agape.

"Did you see that?" Mr. 9 muttered, his voice shaking. "That speed... What was that?"

Miss Monday clenched her fists, frustration evident on her face. "Whatever it was, they're gone now."

Back at the ship, Mira had already started preparations to leave, sensing the urgency of the situation. She paced the deck, muttering curses under her breath. When Isaac appeared out of thin air, landing lightly on the deck with Kieran and Nolan in his arms, she stopped in her tracks.

"About time!" she snapped, though her tone softened when she saw Kieran's unconscious state. "What the hell happened?"

Isaac carefully laid Kieran down, his green aura flickering out as he exhaled heavily. "Long story short? Trouble. But we're out of it for now."

Nolan slid off Isaac's back, still shaking. "Isaac… how did you get here so fast?"

Isaac smirked faintly, though his face was pale from exertion. "The laws of motion aren't just for fighting. Let's just say I bent the rules a bit to get here in time."

Mira didn't waste a moment. She grabbed the ship's wheel and began steering them away from the island. The sails unfurled, and the ship caught the wind, speeding toward open waters.

"Whatever went down in that village, we're not sticking around to find out," Mira said firmly. "This is the Grand Line. Trouble's everywhere, and we can't afford to be caught off guard again."

Isaac nodded, sitting down heavily against the ship's railing. He glanced at Kieran, his brow furrowed with concern. "We'll figure out what's going on with him. But first, we need to put some distance between us and that place."

Nolan sat beside Kieran, his hands gripping his knees tightly. "He's gonna be okay, right?"

Isaac rested a reassuring hand on Nolan's shoulder. "He's tougher than he looks. He'll pull through. And so will we."

Isaac stared at the sea, his thoughts drifting back to the moment he had arrived to save Nolan and Kieran. 'How did I pull that off?' It wasn't the first time he had pushed his abilities to their limits, but this felt different—far more dangerous than anything he had attempted before.

Isaac leaned his head back against the wooden railing, his eyes narrowing as he replayed the moment in his mind. 'I removed the forces that would naturally resist my movement, including drag, friction, and gravity. Without those forces, there was nothing to stop me from accelerating to theoretically infinite speeds.' He frowned, his hands clenching slightly. "But…"

The problem became immediately apparent. Moving at such extreme speeds came with its own set of risks, risks that could easily spell his end. His body wasn't designed to handle the forces involved, even if he could temporarily negate them. 'At those speeds, even a single miscalculation could destroy me. If I hadn't reapplied the forces to slow myself down when I stopped… I could have been atomized.'

The very thought made his stomach churn. His abilities were incredible, yes, but they weren't without their limits. Every technique he developed had a price, and this one seemed to demand the highest cost yet. The green aura—the faint glow of his energy—was proof of how much strain it had placed on his body. Blood crusted around his nose, a stark reminder of how close he had come to overexertion.

"It's not sustainable," he muttered to himself, his voice barely audible over the sound of the waves. "Not yet. If I use that recklessly, I won't survive the next time."

Still, the technique had potential. If he could refine it, control it better, maybe even reinforce his body to handle the strain, it could become a powerful tool. The ability to move faster than anyone could react was an advantage few could counter.

But for now, it was more of a risk than a reward.

Isaac exhaled deeply, wiping his face with the back of his hand. He turned his gaze toward Kieran, who lay unconscious nearby, and then to Nolan, who sat vigilantly beside him. A faint smile tugged at his lips. "At least it worked," he said softly.

Even so, he knew he'd have to be smarter moving forward. The Grand Line wasn't going to get any easier, and neither were the enemies they'd face. He'd have to push himself harder—train not just his strength and speed, but his control, his precision. Because if he couldn't master his abilities, they might end up being the very thing that destroyed him.

His eyes suddenly fixed on Nolan, who was carefully tending to Kieran's unconscious form. Mira stood at the helm, focused on steering them away from Whiskey Peak, her expression grim after everything they'd just escaped.

Isaac broke the silence. "Hey, Nolan. What the hell happened back there? The village—half of it is just… gone. Was it those bounty hunters?"

Nolan sighed, setting down the damp cloth he'd been using to cool Kieran's forehead. "Not exactly," he said, his tone hesitant. He glanced at Kieran's motionless form. "It was Kieran."

Isaac's brow furrowed in confusion. "What do you mean it was Kieran? He was fighting, sure, but that kind of destruction? That doesn't make sense."

Nolan sat back, rubbing the back of his neck. "I didn't see everything, but when he was fighting those two—Miss Monday and Mr. 9—something happened. He grew extra arms, like… two more out of his shoulders. And then…" He hesitated, clearly struggling to explain what he'd witnessed. "A third eye opened on his forehead. It wasn't normal. It glowed, and then this beam just… shot out of it."

Isaac blinked, stunned. "A beam?"

Nolan nodded. "Yeah, and he didn't seem to know what he was doing. It just… happened. He turned his head, and the beam swept across the village. That's what destroyed everything. It was like he couldn't control it."

Isaac leaned back, processing what he'd just heard. "That doesn't sound like anything I've ever heard of. Did he say anything about his fruit before all this?"

Nolan shook his head. "Nothing."

Isaac looked at Kieran, still unconscious, his breathing steady but labored. "We need to figure out what he ate. A fruit like that—extra arms, a third eye, beams of destruction—it's not normal."

Nolan nodded in agreement. "I've been trying to think about it, but nothing fits. It's not one of the standard Zoans or Logias we've read about, and it doesn't seem like any Paramecia I've heard of. It might not even be documented."

Isaac frowned. "That's not good. If it's undocumented, then we're flying blind. And if Kieran can't control it…"

Nolan finished the thought grimly. "It could be dangerous for all of us."

They sat in silence for a moment, the weight of the situation pressing down on them.

"We'll have to figure it out as we go," Isaac said finally. "But for now, we keep him safe. When he wakes up, we'll ask him if he felt anything—or if the sword has something to do with it."

Nolan glanced at Chandrahas, still lying beside Kieran. Its polished blade gleamed faintly, almost as if it had a life of its own. "That sword… it's not normal either."

Isaac nodded. "Nothing about this situation is normal."

As the ship rocked gently on the waves, they both exchanged a determined glance. The Grand Line was already proving to be far more chaotic than they'd anticipated, but they weren't about to let it overwhelm them. Together, they would figure it out—even if it meant diving into the unknown.
