The Iron Will glided smoothly into Shells Town's harbor, its sleek design catching the eyes of onlookers. Luffy, standing at the helm, felt a surge of excitement. This was where his journey would truly begin, where he would recruit his first crewmate—Roronoa Zoro.

As Luffy disembarked, he moved with purpose through the bustling town, his straw hat casting a shadow over his determined eyes. The Marine base loomed large at the center of the town, and he knew Zoro was there, tied up and awaiting execution. But Luffy had no intention of letting that happen.

Koby, who had stayed behind initially, couldn't shake the unease gnawing at him. His admiration for the Marines had brought him this far, but Shells Town didn't feel right. Determined to learn more, he ventured into the town, listening to the conversations of the townsfolk. What he heard disturbed him deeply—Captain Morgan was a tyrant, ruling through fear and brutality.

As Koby explored further, he saw the truth for himself. Marines were extorting the townspeople, threatening them with violence if they didn't comply. Koby's heart sank as he watched a shopkeeper hand over his hard-earned money, trembling in fear. This wasn't the justice Koby had believed in. The realization hit him like a punch to the gut—the Marines here were no better than the pirates they were supposed to fight.

Luffy arrived at the Marine base's courtyard, where Zoro was tied to a wooden post. Even in his battered state, Zoro's presence was formidable, his eyes burning with defiance. Luffy approached with a calm confidence, meeting Zoro's gaze.

"You're Roronoa Zoro, right?" Luffy called out.

Zoro looked up, his gaze sharp and unyielding. "And who the hell are you?"

"I'm Luffy," he replied with a grin. "I came here to see if the stories about you were true."

Zoro's expression hardened. "You've seen me. Now get lost."

Luffy's grin didn't falter. "I heard you're waiting for someone to keep a promise. But Helmeppo doesn't plan on keeping it. He's going to let you rot here and then execute you."

Zoro's eyes darkened, a flicker of doubt crossing his face. "Why should I believe you?"

"You don't have to," Luffy replied seriously. "But staying here isn't going to make you stronger. You want to be the greatest swordsman, right? You can't do that if you're dead. And you can't do it by staying in the weakest Blue of all."

Zoro stared at Luffy, surprised that this stranger knew so much about him. "How do you know about my dream?"

Luffy chuckled. "I only accept people with great dreams in my crew. And I make it a point to know who they are."

Zoro's mind raced. There was something about Luffy—his confidence, his determination—that made Zoro consider the offer. Finally, he spoke. "What are you suggesting?"

"I'll get your swords from the Marine base," Luffy said, his tone firm. "If you can cut me down with them, you're free to go and do whatever you want. But if you can't, you join my crew and help me become the Pirate King."

Zoro's eyes narrowed. "You're serious?"

"As serious as I can be," Luffy replied.

Zoro considered the proposition. He had nothing to lose and everything to gain. After a moment, he nodded. "Alright, you've got a deal."

Luffy turned to leave but paused to look back at Zoro. "Hang in there. I'll be back soon."

As Luffy made his way to the Marine base, he noticed someone moving stealthily through the shadows. It was the same girl he had seen during his encounter with the Alvida Pirates—Nami. She was clearly up to something.

Nami was so focused on her task that she didn't notice Luffy until he was almost upon her. She spun around, dagger in hand, ready to defend herself. "You again? What are you doing here?"

Luffy tilted his head, giving her an amused look. "I could ask you the same thing. What's a thief like you doing sneaking around a Marine base?"

Nami narrowed her eyes, sizing him up. "None of your business. But since you're here, how about we make a deal? You help me get what I need, and I'll help you with whatever you're after."

Luffy's curiosity was piqued. "What are you after?"

Nami hesitated before answering. "There's a map of the Grand Line in the base. I need it."

Luffy's eyes gleamed with interest. "A map of the Grand Line? That's useful. Alright, I'll help you, but you help me get Zoro's swords."

Nami blinked in surprise. "Zoro? You mean that swordsman they've got tied up in the courtyard?"

Luffy nodded. "Yep. He's going to join my crew, but he'll need his swords first."

Nami considered the offer. She needed that map, and Luffy seemed capable. "Fine. But this is just a temporary alliance."

"Works for me," Luffy said with a shrug.

As they approached the entrance to the base, Luffy and Nami were stopped by a group of Marines. "Halt! What's your business here?" one of them demanded.

Luffy didn't bother with an explanation. "Get out of my way," he said, his voice calm but commanding.

The Marines sneered, clearly not taking him seriously. "You've got a lot of nerve, kid. Let's teach you a lesson."

Luffy's expression didn't change. As the Marines advanced, he moved with lightning speed, delivering powerful punches that sent them sprawling. The Marines barely had time to react before they were incapacitated, groaning in pain on the ground.

Nami watched in awe as Luffy took down the group with ease. She had seen skilled fighters before, but this was different. "Who are you?" she whispered, more to herself than to Luffy.

Luffy glanced at her, his grin returning. "Just a guy with a dream."

They continued deeper into the base, encountering more resistance, but Luffy handled each encounter with the same calm efficiency. It wasn't long before they reached the armory where Zoro's swords were being kept.

Luffy retrieved the swords, admiring their craftsmanship. As he held them, he couldn't help but feel a sense of respect for the swordsman who wielded them. He turned to Nami. "Got what you need?"

Nami nodded, holding up a rolled-up map. "Got it. Let's get out of here."

Just as they turned to leave, the doors to the armory were kicked open, and Captain Morgan strode in, his iron jaw gleaming under the dim light. His massive axe was slung over his shoulder, and his eyes were full of contempt. "Who dares defy me in my own base?"

Luffy stepped forward, eyes narrowing. "You're Morgan? I've heard about you—how you've been terrorizing this town."

Morgan sneered. "You're just a piece of pirate trash! You think you can walk in here and challenge me?"

Luffy's gaze hardened. "I'm not here to challenge you. I'm here to take you down."

With a roar, Morgan charged at Luffy, swinging his massive axe in a wide arc. Luffy dodged the strike with ease, moving fluidly as he avoided Morgan's follow-up attacks. Each time Morgan's axe missed its mark, it tore into the walls and floor, leaving deep gashes and sending debris flying.

Luffy closed the distance, moving faster than Morgan could track. He delivered a powerful punch to Morgan's midsection, sending the Marine captain staggering backward. Morgan growled in frustration, swinging his axe again, but Luffy was already behind him. With a series of rapid strikes, Luffy targeted Morgan's joints, his blows precise and unrelenting.

Morgan's movements grew sluggish as the pain and exhaustion took their toll. Luffy didn't let up, his fists moving with incredible speed and power. The final punch sent Morgan crashing into his own statue, which toppled over and shattered into pieces as Morgan slumped to the ground, defeated.

Nami watched in stunned silence as Luffy dismantled the tyrant with ease. She had never seen anyone take down a Marine captain like that. It was clear that Luffy was more than just a pirate—he was someone to be reckoned with.

With Morgan defeated, Luffy turned to Nami. "Let's go."

As they left the base, Koby, who had been watching from a distance, finally caught up with them. He had seen the entire fight, and the realization of the Marines' corruption had shaken him to his core. "Luffy… what I saw… the Marines… they're not what I thought they were."

Luffy placed a hand on Koby's shoulder. "You've seen the truth now. It's up to you to decide what to do with it."

Koby nodded, his resolve hardening. "I want to join the Marines, but I want to change them from the inside. I want to bring real justice."

Luffy smiled. "Then you'll do great, Koby."

Back in the courtyard, Zoro was surprised to see Luffy return with his swords. "You actually did it," Zoro said, his voice tinged with disbelief.

Luffy grinned, tossing the swords to Zoro. "A deal's a deal. Now, let's see if you can cut me down."

Zoro took his swords, feeling their familiar weight in his hands. He drew them with a practiced ease, the blades gleaming in the sunlight. "You're crazy, you know that?" Zoro said, though there was a hint of respect in his tone.

Luffy just laughed. "Maybe. But I'm not going to die here."

Zoro charged at Luffy, his swords moving in a blur. But no matter how fast or precise his strikes were, Luffy dodged them all, his movements fluid and effortless. Zoro pushed himself harder, determined to land a hit, but Luffy's agility and Haki were too much.

As Zoro's frustration grew, Luffy decided it was time to show him the difference in their abilities. With one swift motion, Luffy activated his Armament Haki, his arm turning jet black as he caught Zoro's sword with his bare hand. The blade didn't even make a scratch.

Zoro's eyes widened in shock. "What… what is this?"

Luffy's expression turned serious. "This is Armament Haki. It's something you'll need to master if you want to survive in the Grand Line. Staying in the weakest Blue isn't going to make you stronger."

Zoro gritted his teeth, the realization hitting him hard. Luffy was on a completely different level. But instead of feeling defeated, Zoro felt a spark of determination. This was the kind of challenge he had been looking for.

Luffy released the sword and stepped back. "So, what's it going to be?"

Zoro sheathed his swords, his respect for Luffy evident in his eyes. "Alright. I'll join your crew. But don't think I'm going to go easy on you."

Luffy laughed, clapping Zoro on the back. "Wouldn't have it any other way."

Nami, who had been watching the entire exchange, couldn't help but feel drawn to the camaraderie between the two. Luffy's confidence, Zoro's strength—it was something she had never seen before. She knew she had her own mission, but for the first time, she wondered if maybe, just maybe, she could find a place with these two.

As they prepared to leave Shells Town, Nami spoke up. "I know I said this was a temporary alliance, but… maybe I could stick around for a bit. Just until I find what I'm looking for."

Luffy smiled, his expression welcoming. "Sure. The more, the merrier."

Before they could depart, the townspeople, having heard of Morgan's defeat, began to gather around the Marine base. Their expressions were a mix of relief and gratitude. The Marines, who had been under Morgan's oppressive rule, also approached Luffy, their previous hostility replaced by a grudging respect.

"Thank you," one of the townspeople said, stepping forward. "Morgan's tyranny has been a nightmare for us all. We… we don't know how to repay you."

Luffy waved off their thanks with a grin. "No need to repay me. Just live your lives freely from now on."

The Marines who remained behind saluted Luffy, acknowledging that he had rid them of a corrupt leader. "We'll make sure the town is protected," one of the Marines said, his voice filled with resolve. "We'll do our best to uphold real justice from now on."

Luffy nodded, satisfied. As they returned to the Iron Will, Luffy, Zoro, Nami, and Koby knew that this was just the beginning. They had each taken a step toward their own dreams, but they had also found something more—friends, allies, and a cause worth fighting for.

As the ship sailed out of the harbor, the wind at their backs and the open sea before them, Luffy knew that the journey to become the Pirate King had truly begun.
