The New World was not merely an ocean; it was a graveyard of ambition. To navigate its treacherous waters required an unyielding will. For the Marines of the G-5 branch, stationed at the very vanguard of this chaotic sea, dealing with the impossible was simply part of the daily routine.

Cutting through the dark, churning waves miles away from the erupting inferno of Punk Hazard, a Marine battleship plowed forward.

Smoker stood at the bow, staring out toward the horizon with two cigars permanently clamped between his teeth, his expression carved from stone.

Behind him, Captain Tashigi approached, adjusting her glasses and clutching her katana. "Vice Admiral Smoker. The men have secured the perimeter, but the navigational data is... troubling. We are officially in the dead zone."

Smoker didn't look back, his eyes narrowed as he stared at the faint, fiery glow illuminating the distant clouds. "Troubling isn't the word for it, Tashigi. It's madness. Tell me the readings on the Log Pose again."

Tashigi lifted her wrist, looking at the New World Log Pose. "All three needles have stabilized. They point toward Raijin Island, Risky Red Island, and Mystoria Island. Standard protocol for any pirate crew entering the New World from Fish-Man Island would be to follow one of those three routes."

"Standard protocol," Smoker scoffed, exhaling a thick plume of gray smoke. "When has 'Straw Hat' Luffy ever cared about standard protocol? Or rules? Or basic logic?"

Tashigi hesitated, recalling the trail of destruction the Straw Hat Pirates left in their wake. "Never, sir."

"Exactly," Smoker growled, gripping his jutte. "There are three islands he could have gone to. Three logical, charted paths. But I know that idiot. If there's an invisible path, a path that screams danger, a path that isn't even supposed to exist... that's the one he takes. He hasn't gone to Raijin, Risky Red, or Mystoria."

Smoker pointed his jutte toward the distant, glowing horizon. "He's gone to Punk Hazard."

The G-5 Marines standing nearby muttered among themselves, unease rippling through their ranks.

"Punk Hazard?" Tashigi repeated in alarm. "But Vice Admiral, that's impossible. Punk Hazard has been strictly cordoned off by the World Government. It doesn't even emit a magnetic field anymore. After the catastrophic incident 2 years ago... the island is a dead wasteland. It's strictly off-limits."

"To a normal pirate, maybe," Smoker replied gruffly. "But Straw Hat isn't normal. And wherever he goes, the balance of the world tips. Set a direct course for Punk Hazard. If he's there, I'm bringing him in."

Meanwhile, anchored in the turbulent, boiling waters just off the coast of the blazing island, the Thousand Sunny was a hive of energy.

The ship sat comfortably in the water. Protective runic wards kept the intense heat radiating from the flaming ocean at bay. The deck was cool despite the literal sea of fire surrounding them.

On the deck, the crew had gathered in a circle. In the center, Franky held out a fistful of identical wooden straws.

"Alright!" Franky announced. "The rules are simple! We've got a distress signal from a burning hellscape. The captain wants to go, which means a scouting party needs to be established. Whoever draws the short straws... goes with Luffy!"

"I don't want to go! I have 'Can't-Go-To-Burning-Islands' disease!" Usopp cried, shaking his head.

"Don't be a baby!" Jewelry Bonney laughed, casually tossing an apple into the air and catching it. "It's the New World! If we're not running into burning islands and deadly traps, we're not doing it right. I'm in!"

"Bonney is already volunteering, so that leaves a few more spots," Nami sighed, leaning against her Clima-Tact. "I'm staying right here. Somebody has to monitor the weather patterns, and that island looks like a navigational nightmare."

"I shall remain and defend our lovely ladies!" Sanji declared.

Luffy marched right up to Franky and ripped a straw from his grip. "I'm going no matter what!"

One by one, the crew stepped up to draw their fate.

Zoro casually pulled a straw. It was short. He smirked, resting his hand on his sword. "Good. I need to stretch my legs anyway. And I want to meet this samurai the snail mentioned."

Robin stepped forward, plucking a straw from Franky's hand. Short. "It seems I will be joining you, Captain. An abandoned island with a hidden history... it sounds quite intriguing."

Caroo waddled forward with determination. He grabbed a straw with his beak and pulled. Short.

Vivi smiled, petting her companion. "Be careful out there, Caroo. Look after everyone."

Finally, only one spot remained. Usopp reached out and pulled the straw.

He stared at it. It was barely two inches long.

"NOOOOOOO!" Usopp screamed, falling to his knees. "Why?! The universe hates me! I'm going to roast!"

"Stop crying, Usopp," Zoro grunted.

"I don't want to gooooo!" Usopp sobbed.

Sanji walked out of the galley, holding a bento box. "Here you go. I made a special deep-sea fish lunchbox. I used the remaining meat from the sea king Zoro didn't completely ruin, packed with cooling herbs from the Momoiro garden. It'll keep your internal body temperature stable even if you walk into a furnace."

He handed the box to Luffy, who immediately tried to open it, only for Sanji to kick his hand away. "Eat it on the island, rubber-brain!"

"Alright, scouting party, let's go!" Luffy cheered.

Luffy placed two fingers in his mouth and let out a sharp, piercing whistle that echoed across the deck.

The Flying Nimbus plummeted from the sky, coming to a floating halt right next to Luffy. Luffy hopped onto the cloud with a wide grin.

"Hop on, Bonney!" Luffy offered.

Bonney didn't hesitate, vaulting over the railing and landing smoothly on the Nimbus, wrapping her arms around Luffy's waist. "This thing is awesome!"

Beside them, Robin crossed her arms. "Cien Fleur: Wing."

Instantly, arms sprouted from her back, interlocking to form a pair of wings. With a gentle flap, she lifted off the deck, hovering in the air.

"I suppose I'll take the scenic route," Robin smiled.

Zoro cracked his neck. Zoro kicked off the deck, using Geppo to step across the air.

Caroo waddled forward. The duck tapped the metallic bracelet on his leg. Nanotech rippled over his feathers, hardening into red-and-gold armor. An arc reactor flared on his chest. With a mechanical hum, the thrusters on his feet ignited, and he shot into the sky, letting out a synthesized, metallic "QUACK" of triumph.

Usopp sighed, adjusting his goggles. "Fine. If you can't beat 'em, join 'em."

Usopp flexed his back, sprouting two falcon wings from his shoulder blades. With a powerful flap, he soared after the others.

The six of them flew over the boiling, fiery sea, leaving the safety of the Sunny behind.

Ahead of them, the island loomed—a spectacle of geological violence. Half of the landmass was consumed by an unending inferno, while the other half, separated by a circular crater lake, was buried under an apocalyptic blizzard.

They approached the burning half, the shoreline obscured by thick, black smoke.

As they touched down on the rocky, ash-covered shore, the heat hit them like a physical wall. The ground beneath their boots was scorched and cracked.

Before them stood a colossal metal barricade with the World Government and Marine logos. A warning sign hung across the front: RESTRICTED AREA. NO ENTRY. EXTREME HAZARD.

"Whoa," Bonney muttered, stepping off the Nimbus. "They really don't want anyone coming in here. Those gates look like they could withstand a Buster Call."

Usopp landed behind her, his falcon wings retracting seamlessly into his back. He took one look at the logos and panicked. "World Government?! Marines?! Oh, no! We can't go in there! That's restricted!"

Luffy picked his nose, staring blankly at the sniper. "Usopp, what are you talking about?"

Zoro walked past Usopp, not even breaking his stride. "He's right, Usopp. We definitely shouldn't make the World Government mad."

In a flash of motion, Zoro drew his blade, slashed, and sheathed it again.

The gates groaned. A perfect, diagonal line appeared across the structure. With a screech, the top half of the gates slowly slid off, crashing into the ground behind them, kicking up a cloud of ash and embers.

"Too late," Zoro smirked, stepping right over the molten, freshly cut steel.

Usopp fell to his knees. "Zoro, you maniac! They're gonna send an Admiral after us! They're gonna—" Usopp suddenly stopped. He blinked, looking up at the sky, the realization slowly dawning on him. "Wait... we burned down their flag at Enies Lobby. We broke into Impel Down. We literally fought in the Thriller Bark. And Zoro stepped on a Celestial Dragon face, well kind of."

Usopp stood up, brushing the ash off his knees,his panic instantly evaporating. "Oh, right. We're already the most wanted criminals in the world. Never mind! Let's go!"

The group walked through the ruined gates, entering the restricted zone of Punk Hazard.

The landscape was a vision of desolation. What had once been a highly advanced, fortified facility was now a graveyard of melted steel and scorched concrete. Puddles of molten rock bubbled across the pathway.

Robin walked through the ruins, her eyes scanning the destroyed architecture. "Fascinating. Looking at the structural foundations and the remaining insignia on these melted towers... this was undeniably a former government base. Most likely a high-level research facility, given the isolation and the security measures."

"A research facility?" Bonney asked, looking around the wasteland. "What kind of research causes half an island to catch fire and the other half to freeze?"

"That is the question, isn't it?" Robin mused.

"Hey, wait a second," Usopp said, looking around as he activated the targeting sensors in his goggles. "Something doesn't make sense. The guy on the Den Den Mushi... remember what he said? He said it was freezing. He was shivering."

Usopp wiped sweat from his brow. "Look around! We're walking through an actual oven! How could he possibly be cold?"

Luffy tilted his head. "Maybe he was just stupid. Or he had a really bad fever."

"People with fevers don't usually call random pirates for help while getting sliced up by a samurai," Zoro pointed out.

Robin touched her chin, looking up toward the sky. "The island is divided. The climate here is entirely artificial. It stands to reason that if this half is a blazing inferno, there must be a freezing sector somewhere else on this island. The distress signal likely originated from the cold zone."

Back on the Thousand Sunny, Nami was standing with Vivi, peering through a set of binoculars. She frowned, adjusting the lenses.

"Robin is right," Nami murmured, speaking into a wrist-communicator connected to the scouting party. "I can see the atmospheric divide from here. The thermals are completely insane. The heat from your side is rising and violently clashing with an artificial cold front on the far side of the island. There are dense, heavy snow clouds completely blanketing the northern hemisphere of Punk Hazard."

"Got it, Nami!" Luffy's voice crackled through the communicator. "We'll just keep exploring this side for now! Bye!"

Nami sighed, lowering the binoculars. "He's going to find something terrible to fight, isn't he?"

"Undoubtedly," Vivi smiled.

Back in the burning ruins, Luffy's group continued their trek deeper into the melted city.

They stumbled into a courtyard. It was now a blackened crater. But it wasn't the crater that stopped them in their tracks. It was the object sitting in the center of it.

"By the gods," Robin whispered.

Laying in the ash was a skull. But the scale of it was massive—bigger than the Sunny, bigger than Dorry and Brogy, bigger than a marine battleship. It was a skull with two massive, curved horns.

"Is that... a giant?" Usopp stammered, his knees beginning to knock together.

"No," Zoro said, looking at the size of the structure. "This thing makes a giant look like a toy. What the hell was that?"

The ground beneath them shook. A shadow fell over them. The temperature in the courtyard, already sweltering, rose.

"Uh, guys?" Bonney said, slowly looking up. "I don't think we're alone."

The crew looked up. Standing atop the giant skull was a dragon, covered in thick red scales. The beast lowered its reptilian head, its golden eyes locking directly onto them.

"A... A... A DRAGON?!" Usopp screamed.

Caroo took one look at the beast, let out a synthesized squeak, and immediately engaged his thrusters to hover behind Zoro.

"Awesome!" Luffy yelled, his eyes shining. "It's a real dragon! I want it!"

The dragon shifted its weight, its talons carving deep gouges into the skull. Then, the beast opened its mouth, and a deep, rumbling voice echoed across the courtyard.

"Who are you?" the voice demanded. "Have you come to challenge me?"

Usopp grabbed Luffy by the collar, shaking him. "Luffy! The dragon! The dragon is talking! We need to run! We need to leave this island right now!"

"Are you guys with that Warlord of the Sea?" the voice echoed again, sounding oddly distorted.

"Warlord?" Robin repeated, her mind racing.

Before anyone could answer, the dragon's golden eyes narrowed. It reared its head back, a blinding light building in its throat. It unleashed a torrential river of roaring flames, hurtling directly toward them.

"I got this!" Luffy laughed.

Luffy didn't dodge. Stepping forward, he pulled his right arm back. His arm turned glossy black, coated in Armament Haki with red and black lightning crackling around his fist. Luffy threw his punch into the incoming inferno.

BOOM

The force of the punch tore the flames apart, splitting them down the middle. The shockwave traveled forward and slammed directly into the dragon's snout.

The beast's eyes rolled back as its head snapped backward. With a gurgling groan, the dragon collapsed onto the skull.

The courtyard fell silent, save for the crackling of the distant fires.

"Got 'em!" Luffy grinned, proudly raising his fist.

Zoro clicked his tongue in annoyance, sheathing his swords. "Oi, you idiot captain! Why the hell did you punch it right in the head?! I was right behind you — I could've sliced it!"

Luffy blinked, then turned to him with a frustrated look. "What are you talking about, Zoro?! If I let you cut it, the meat would've been all over the place! This way it stayed in one piece!"

Zoro scowled. "One piece? You smashed its skull in! Now the best parts are probably ruined. I was gonna cut it properly so Sanji could barbecue the tail and wings. Dragon meat is super rare, you moron!"

Luffy crossed his arms, looking genuinely annoyed. "Shishishi, you're wrong! Punching it was way better! If you sliced it, half the good meat would've fallen off the cliff or something. My way is cleaner for barbecue!"

"Cleaner?! You call that clean?!" Zoro growled, pointing at the collapsed dragon. "Now Sanji's gonna complain that the head's all busted up. I wanted proper dragon steak!"

"You guys are crazy," Bonney muttered, staring at them in disbelief. "You just one-shot a dragon and you're arguing about barbecue techniques?"

From the top of the skull, the voice echoed once more, muffled but conscious.

"Curse you! You dare strike me? I am a proud samurai of Wano!"

"Wait," Usopp said. "If the dragon is knocked out... why is it still talking?"

The crew froze.

"It... It really is talking," Zoro said, his brow furrowing. "But it's knocked out cold."

"The voice isn't coming from the mouth. It's coming from the top of its head!" Luffy said.

Luffy stretched his arms, grabbing the edge of the skull, and slingshotting himself to the top of the pile. He landed on the dragon's snout.

"Hey! Where are you?!" Luffy yelled.

"Get off me, you brute!" the voice yelled back.

Luffy looked down. Lodged tightly between the dragon's brow ridges were a pair of human legs.

They were wearing traditional striped hakama pants and geta sandals, kicking the air.

"Whoa!" Luffy laughed, squatting down. "It's a pair of legs! And they're talking!"

"Release me!" the legs commanded, kicking wildly.

"Okay!" Luffy agreed. He grabbed the legs by the ankles and pulled.

With a pop, the legs came flying out.

Luffy tumbled backward, holding them, and presented them to the crew.

The crew stared in silence.

Luffy was holding a pair of human legs. But that was all he was holding. From the waist up, there was nothing. It was just a lower torso, cut perfectly clean at the waist, with no blood, no organs, just an empty void.

"Luffy! You ripped him in half! You killed him!" Usopp screamed.

"I killed him?! Oh no! I didn't mean to! I just pulled!" Luffy cried.

The legs twisted out of Luffy's grip, landing upright. "You dare attempt to manhandle me?! Taste my blade! Swordless Style!"

The legs leaped, delivering a kick at Luffy's face. Luffy ducked. The kick shattered a piece of the dragon's horn.

"Whoa! You're alive!" Luffy cheered.

The legs turned and sprinted away, darting through the ruins.

"Cowards! I shall regroup!" the legs yelled.

Luffy ran to the edge of the skull, cupping his hands. "HEY! LEGS! JOIN MY CREW!"

"Luffy... you can't invite a pair of disembodied legs to join the crew! Please stop doing that!" Usopp groaned.

"But they're so cool!" Luffy argued, jumping down to rejoin them. "We have a skeleton, a cyborg, a magic guy, a reindeer, Gaints and a duck! A pair of fighting legs fits perfectly!"

Robin smiled elegantly, covering her mouth with her hand. "Fufufu... How fascinating. It seems the poor man misplaced his upper body. At least the legs are still running around. The torso is probably somewhere decomposing nicely by now."

Usopp jumped back, pale. "Robin! Stop! That's terrifying!"

Carue flapped his wings wildly beside him. "Quack! Quack! Quack!" 'Yeah, stop scaring us like that!'

Zoro smirked. "He said he was a samurai of Wano. That means the other half of him is somewhere on this island. If he's the one who made the call... we need to find the rest of him."

Robin nodded. "It seems we have a mystery to solve. The dragon, the base, the Warlord, and the bisected samurai. Shall we proceed, Captain?"

Luffy adjusted his straw hat. "Yeah! Let's go catch those legs!"
