The heavy, reinforced security doors of Building C hissed open with a sharp, pressurized release of steam. Stepping through the threshold was Caesar Clown, his gaseous, indigo-tinted form billowing out aggressively as he filled the sterile corridor. His face was twisted into a mask of fury, his sharp teeth bared as his yellow eyes locked onto the intruders.

"Who gave you permission to touch my equipment?!" Caesar shrieked, his voice echoing shrilly off the metallic walls of the laboratory. "You filthy, ignorant pirates! Do you have any idea what those machines are?! That is the pinnacle of scientific achievement! My life's work!"

Ben did not even look up from the primary research console. He casually clicked the cap back onto his red marker, tossed it into the air, and caught it with a practiced flick of his wrist.

"Your life's work is a complete mess," Ben said, his tone dripping with casual indifference. "I've seen amateur alchemists with better structural logic. There were dozens of mathematical errors in your gas compression formulas. I had to go through and correct them so your data wouldn't look completely pathetic. Frankly, you are not much of a genius, are you?"

Caesar's face turned an explicit shade of purple. His gaseous body expanded violently, filling the upper half of the room with a swirling vortex of toxic purple gas. "You think you can mock me?! I am Caesar Clown! The greatest scientist of the New World! I will turn your lungs to ash, you arrogant—"

Before the villain could even finish his sentence, the space around Ben warped.

With a silent flash, Ben completely vanished from the console. In a millisecond, he reappared directly above Caesar's floating form. His right fist was already drawn back, coated in a dense, suffocating layer of black Armament Haki that bled dark, crackling streaks of Conqueror's Haki into the surrounding air.

"Ruler's Descent."

Ben dropped like a meteor, slamming his fist straight into the crown of Caesar's head.

The impact was instantaneous and devastating. The sheer force of the Conqueror's Haki completely bypassed Caesar's Logia intangibility, shattering his concentration and sending a shockwave rippling through the floorboards. The entire room rattled as Caesar's eyes rolled back into his head, his jaw unhinging as a single, muffled choke escaped his throat. The toxic gas instantly evaporated as the scientist dropped straight to the floor, completely knocked out in a single blow.

Ben landed gracefully on his feet, not even breaking a sweat. He extended his hand, throwing open a swirling, dark tear in the fabric of reality—his personal spatial dimension. With a casual nudge of his boot, he rolled Caesar's limp, unconscious body into the void, closing the rift behind him.

"Well, that takes care of the landlord," Ben said, brushing a speck of dust off his shoulder. He looked back at his group. "Let's keep moving. Let's see what more is hidden away in this facility."

Franky grinned, punching his massive palms together. "Super! That guy was all talk and no iron anyway!"

As the group resumed their search, tearing through drawers and cataloging blueprints, Oimo suddenly paused near the center of the room. He closed his eyes, tilting his head toward the floor as his Observation Haki spread outward, permeating through the thick layers of steel and concrete beneath their boots.

"Hey, Ben," Oimo called out, his voice entirely calm despite the discovery. "I feel a life signature. It's faint, but there's definitely something breathing directly below us."

Ben closed his eyes, activating his own Observation Haki. A sharp, distinct pulse of energy flared in his mind, confirming the giant's words. "You're right. It's from the lower sub-levels. Let's check it out."

The group descended a rusted spiral staircase, entering a dark, cavernous vault that smelled heavily of stagnant chemicals and decay. This was the garbage disposal area—a massive, forgotten chute where all of Caesar's failed experiments, toxic runoff, and discarded scrap metal were dumped to rot.

Franky stepped forward, activating a small light from his wrist console to illuminate the darkness. The beam swept across mountains of twisted metal and shattered glass until it caught a flash of bright, unusual color amidst the gray trash.

"Hey, look over there," Franky said, squinting. "Is that... a pink eel?"

Nestled within a pile of iron scraps was a small, serpentine creature with pale pink scales, a white underbelly, and tiny, delicate antlers jutting from its head. The moment the light hit its face, the creature flinched violently, its tiny claws digging into the garbage as it let out a sharp, frightened hiss.

"Who goes there?!" the pink eel suddenly shouted, its voice high-pitched but filled with an incredibly haughty, authoritative tone. "Identify yourselves at once! I am not a creature to be trifled with by mere commoners!"

"Whoa, it speaks!" Franky laughed, lowering his light slightly so as not to blind the little creature.

Sunny bounced forward, his face lighting up with curiosity as he crouched down in front of the scrap pile. "Wow! A talking pink dragon! Don't worry, little guy. We're not going to hurt you. I'm Sunny, and this is my papa Ben, and the rest of our crew!"

The little dragon blinked, his fierce golden eyes shifting from Sunny to Ben, who was standing quietly with his arms crossed. The mention of "papa" seemed to ease some of the creature's immediate hostility, though he still drew himself up with immense, trembling pride.

"I am not an eel, nor am I a mere lizard!" the creature declared, puffing out his tiny chest. "I am a samurai of Wano Country! My name is Momonosuke!"

"A samurai, you say?" Brook mused, floating over with interest. "My, what an incredibly elegant name for such a small young master."

Once Momonosuke realized the group wasn't affiliated with the hazmat-suited guards, his defensive walls began to crumble under the weight of exhaustion. Sitting amidst the garbage, the little pink dragon began to recount the harrowing tale of how he had ended up in the depths of Punk Hazard.

Unlike the rest of the children held captive in the upper levels, Momonosuke explained that he had not been kidnapped from his bed. Instead, he had accidentally stowed away aboard the strange, unmarked ship that was transferring the abducted children across the seas. When the ship docked at Punk Hazard, he had been dragged along with the rest of them into the facility.

"The other children... they were kind to me," Momonosuke murmured, his head dropping as his small claws clutched his tail. "They offered me sweets and food. But due to my strict samurai upbringing, I could not bring myself to accept handouts from strangers or potential enemies. I refused to eat. I starved myself for ten whole days."

"Ten days?!" Sunny gasped, his eyes wide. "That's super long! I'd die without snacks for ten days!"

"Eventually, I reached my limit," Momonosuke admitted, a flush of shame crossing his pink scales. "The hunger was entirely too much to bear. When the guards were distracted, I snuck out of the living quarters to search for sustenance. I wandered deep into the restricted corridors until I stumbled upon the Master's forbidden control room."

He described finding a highly secured, sterile laboratory inside, where a single, bizarrely patterned fruit rested beneath a thick glass display case. Delirious from starvation, Momonosuke hadn't thought twice. He smashed the glass open and wolfed the entire fruit down in a matter of seconds, despite its utterly repulsive taste.

"Shortly after, a young girl—the same one who had checked on me earlier—found me in the room," Momonosuke continued. "We spoke briefly. She wept, telling me how deeply she wished to return home to her mother and father. But before we could slip away, Caesar's men discovered the breached security locks. They burst into the room with weapons drawn."

Momonosuke's breath hitched as he recalled the panic. "We ran. But as the terror gripped me, a strange, burning sensation erupted within my chest. Before I knew what was happening, my body twisted and stretched, transforming me into this serpentine form! I managed to scamper through a small ventilation shaft before the guards could grasp me, but in my haste, I lost my footing and plummeted straight down the garbage disposal chute."

Brook tapped his chin thoughtfully, his skeletal fingers rattling softly. "Yohohoho! A swirling pattern on the fruit, an instantaneous transformation... it seems you have inadvertently consumed a Devil Fruit. A Zoan type, to be precise. You should technically be able to revert back to your human form, though it requires a certain level of mental focus that you likely haven't learned yet."

"A dragon fruit? How fascinating," Franky muttered, rubbing his jaw.

Momonosuke looked up at them, his eyes suddenly filling with a heavy dread. "There is something else... something far worse that you must know. While I was hiding in the upper rafters before my transformation, I overheard Caesar speaking to his underling, the bird-woman named Monet."

The little dragon's voice began to tremble violently. "He was laughing. Monet warned him that the gigantification experiments he was performing on the children were fundamentally unstable. She said that if the treatments continued at this rate, every single one of those children would perish within five years."

The room grew instantly cold. Franky's jaw tightened, and Oimo gripped his club with a sudden, silent fury.

"And what did Caesar say?" Ben asked, his voice low and dangerous.

"He did not care," Momonosuke wept, hot tears spilling over his pink scales. "He snapped at her, saying their deaths were merely an 'unavoidable sacrifice' for the sake of his grand weapons research. He said that once this batch died out, he would simply abduct a fresh group of children from the surrounding islands to continue his work. I tried... I tried so hard to sneak back to the Biscuit Room to warn the others, but that is when the guards found me, and I fell down here..." 𝙛𝓻𝒆𝒆𝒘𝙚𝓫𝙣𝙤𝒗𝙚𝓵.𝙘𝙤𝙢

Before Momonosuke could finish his sentence, a loud, violent rumble echoed from his tiny stomach. The psychological weight of his ordeal, combined with ten days of starvation, finally caught up to him. The little pink dragon's eyes flickered, and his body went entirely limp as he collapsed onto the scrap metal, completely unconscious from hunger.

Ben let out a soft, heavy sigh. He reached into his coat, his hand passing into his spatial dimension for a brief moment before pulling out a small crystal vial filled with a shimmering, deep crimson recovery elixir.

He walked over, gently prying open the little dragon's jaw, and poured the rich potion down his throat. The magical fluid instantly dissolved, sending a warm, nourishing wave of energy through Momonosuke's depleted system. His breathing leveled out, and the frantic trembling in his scales finally ceased as he drifted into a peaceful, deeply needed sleep.

"Oimo," Ben commanded quietly, stepping back. "Pick up the little guy and carry him carefully. We'll let him rest and recover for now. Our business in this sector is finished anyway."

"Understood, Ben," Oimo nodded, gently scooping the sleeping pink dragon into his large hands.

Meanwhile, across the facility, the massive, brightly colored playroom known as the Biscuit Room was currently hosting a massive, chaotic gathering.

Luffy's group along with Trafalgar Law and the captive Brownbeard, had finally navigated the corridors to reunite with Nami's group. The room was filled with the echoing chatter of the giant children, who were currently crowding around Chopper, completely fascinated by his small, fluffy appearance.

Luffy, completely ignoring the tension in the room, was sitting cross-legged on the floor directly in front of the massive alligator-centaur, Brownbeard.

"So you hate us?" Luffy asked, tilting his head with a wide, toothy grin. "Why?"

Brownbeard, heavily bound by ropes but still maintaining a fiercely defiant glare, snorted a cloud of hot air from his nostrils. "I don't just hate you, Straw Hat! I utterly loathe everyone associated with the 'Worst Generation'! You, Marshall D. Teach, and the rest of those eleven arrogant Supernovas have brought nothing but chaos and ruin to the New World!"

He shifted his massive weight, his animalistic lower half twitching in frustration. "Two years ago, I was a feared pirate captain! But the moment I entered these waters, my entire crew was slaughtered, and my original legs were utterly severed from my body by that sadistic bastard, Basil Hawkins! I was left for dead, crawling through the dirt until I miraculously washed ashore on Punk Hazard."

Usopp shivered, wrapping his arms around himself. "Man, that Hawkins guy gives me the creeps."

"You think this island is just a wasteland?!" Brownbeard barked, his voice booming across the playroom. "Four years ago, Punk Hazard was a magnificent paradise full of lush greenery and beautiful forests! It was the primary research headquarters for the world's greatest mind, Dr. Vegapunk! He developed state-of-the-art medical technology, military defense drugs, and advanced weaponry for the World Government. They even brought highly dangerous criminals here from Impel Down to use as test subjects, rather than letting them rot in cells."

Robin narrowed her eyes slightly, her arms crossed beneath her stolen coat. "A paradise... until the disaster."

"Exactly!" Brownbeard nodded fervently. "Four years ago, a massive, catastrophic chemical experiment failed entirely. A horrific explosion tore through two of the three primary laboratories on the island, unleashing a catastrophic wave of highly lethal, paralyzing nerve gas. The blast killed every single piece of plant and animal life across the territory within minutes."

The giant centaur grimaced, the memory clearly burning in his mind. "The government personnel and researchers fled the island in a complete panic, completely abandoning the prisoners and test subjects to save their own skins. Those who were lucky enough to be inside the third, heavily sealed facility survived without injury. But those of us who were left outside on the wasteland were permanently paralyzed from the waist down by the residual nerve toxins."

"That's horrible..." Nami muttered from the side, her hand resting against her chin as she listened closely.

"We were completely helpless," Brownbeard said, his tone softening into a note of profound reverence. "We were doomed to rot in the snow. But then, exactly one year later, a savior appeared! Our magnificent Master, Caesar Clown, returned to the island! Using his gas abilities, he completely cleansed the atmosphere of the remaining poison. He built incredible mechanical floating devices and tailored custom suits so that the paralyzed survivors could finally move and live again!"

He glared directly at Trafalgar Law, who was leaning silently against a massive candy pillar, his face completely expressionless.

"I arrived on this island a year after that, completely broken and ready to give up on life," Brownbeard continued. "But the Master found me. He took me in, fed me, and gave me a purpose. And not too long after that, Trafalgar Law arrived. Using his Room abilities, he performed a grand surgical miracle, replacing our useless, paralyzed lower halves with the powerful limbs of the island's native beasts, forming our proud Centaur Patrol!"

Luffy blinked, pointing a finger toward the ceiling. "Oh! So that's why you're an alligator! What about that big dragon we fought out front? Was that one of Caesar's pets too?"

Brownbeard let out a booming, arrogant laugh. "Ha! You think the Master created that magnificent beast?! How ignorant! That dragon was a legendary genetic masterpiece created by Dr. Vegapunk himself! It was engineered to possess an entirely flawless biological defense system, capable of adapting to any extreme environment on the planet. It was so magnificent that one of the World Nobles from Mariejois eventually claimed official ownership of it as a personal guardian!"

Brownbeard puffed out his chest, completely oblivious to the fact that Luffy and Zoro had casually sliced the beast apart and roasted its hindquarters for breakfast less than an hour ago.

"The Master is a saint!" Brownbeard shouted proudly. "He is conducting grand, top-secret research within this facility entirely for the betterment and advancement of all humanity! You Straw Hats have walked straight into a trap! It is only a matter of time before the Master's forces surround this room, capture every single one of you, and turn your bodies into pickled laboratory specimens for future study!"

Before anyone could respond to Brownbeard's grand speech, the heavy doors of the Biscuit Room suddenly flew inward with a loud, ringing crash.

Everyone spun around, weapons drawing instinctively, only to freeze in utter bewilderment. Sprinting through the doorway at maximum speed was a familiar pair of isolated, disembodied human legs, clad in traditional Wano samurai hakama.

Sitting on a bench near Nami's group, the severed head of Kin'emon suddenly let out a loud, dramatic gasp. His eyes bulged out of his skull as he stared at the doorway.

"MY LOWER HALF!" Kin'emon's head shrieked at the top of his lungs. "THEY HAVE RETURNED TO ME!"

The running legs didn't hesitate. They sprinted across the playroom, launched themselves into the air with a massive leap, and came down directly over the floating head. With a wet, highly distinct shluck sound, the pelvis perfectly fused itself to the base of Kin'emon's neck.

The entire room stared in silence.

Kin'emon stood in the center of the room, completely lacking a torso, chest, or stomach. His bearded head was attached directly to the top of his hips, making him look like a bizarre, heavily compressed biological accordion. He stomped his feet a few times, testing his balance, before drawing himself up with immense, traditional gravity.

"Aha!" Kin'emon declared, his voice echoing loudly despite his lack of lungs. "The heavens have smiled upon me this day! I have regained my mobility! I shall now depart immediately to locate the remaining components of my body, and furthermore, rescue my beloved son, Momonosuke!"

He turned toward the exit, his tiny, compressed body walking with an incredibly stiff, pompous stride. Halfway to the door, he suddenly stopped, his head pivoting around a full 180 degrees to look back at the Straw Hats.

"Make no mistake, pirates!" Kin'emon shouted, pointing a dramatic finger at them. "I am a proud and honorable samurai of Wano! I would rather perish a thousand times over than bend my knee to request assistance from mere outlaws such as yourselves! I shall never ask for your help!"

He paused, clearing his throat loudly. "However... if you were to follow me entirely of your own volition, and perhaps offer your blades to my cause without me explicitly prompting you to do so, I would find it deeply discourteous to refuse your companionship."

A massive, throbbing red cross-mark instantly popped up on the foreheads of Nami, Chopper, Kashi, and Sanji simultaneously. Their patience with the samurai's absurdly dense pride had officially reached its breaking point.

Sanji stepped forward, his eyes burning with comedic fury as a literal aura of flames erupted around his shoulders.

"JUST ASK FOR THE HELP, YOU STUBBORN IDIOT!" Sanji roared.

With a swift, blinding blur of motion, Sanji swung his leg around, delivering a massive, ringing BONK straight to the side of Kin'emon's compressed head. The force of the kick sent the samurai spinning through the air like a top before he crashed face-first into the metal floor.

Without missing a beat, Sanji stormed over, grabbed Kin'emon firmly by both ankles, and flipped him completely upside down.

"We don't have time for your stupid samurai ego drama!" Sanji growled, dragging the upside-down, yelling samurai across the floorboards like a sack of laundry. "Come on! We're going to find your stupid torso right now, whether you like it or not!"

"Unhand me at once, you brute!" Kin'emon yelled, his head scraping lightly against the steel. "This is highly undignified!"

Kashi let out a booming, deep chuckle, lifting his massive iron axe onto his shoulder as he fell into step right behind the cook. "I'll come along to make sure nobody tries to jump you in the dark corridors!"

"Thanks, Kashi!" Sanji called back, completely ignoring the samurai's muffled protests as they marched out into the facility.
