The first half of the Grand Line lay beneath a vast, unbroken expanse of clear blue sky.
The massive black steel dreadnought, the Eclipse, glided steadily through the high-altitude cloud layers, maintaining a uniform, high-speed cruising velocity as it targeted the coordinate matrix of Asuka Island. Today, as was standard for the vessel's routine, the main deck was an arena of absolute, uninhibited chaos.
"Jeno! Is the structural temper on this weapon balanced yet?! My fingers are losing their patience!"
Enel sat cross-legged, suspended in mid-air through his own current control, blue-white arcs of volatile electricity skittering restlessly from his fingertips. Directly beneath his position, Jeno was working shirtless, his metallic torso emitting a heavy, rhythmic grinding sound like a hydraulic forge engine. The mechanic unhinged his jaw to swallow a massive chunk of rare moon alloy alongside a compiled pile of local volcanic ores.
"Cease the screaming! This layout utilizes my newly integrated memory alloy framework, and your weapon requires a completely different threshold for conductivity and thermal dissipation! Even if my internal furnace is automated, the molecular alignment demands absolute precision!"
Jeno slapped his rounded midsection before unhinging his jaw once more, cleanly ejecting several newly forged armaments that gleamed with a dark, silver-grey luster onto the deck plates.
"Behold! The custom armaments of the Eclipse vanguard have officially cleared their upgrades!" Jeno wiped a few metallic filings from his lip, pointing proudly at the array resting on the iron plating.
Sabo stepped forward first, his boot stepping past the line as he hoisted a dark red alloy staff, weighing the metal within his palm. "The density has jumped significantly compared to the old pipe. Jeno, can the core withstand the unmitigated heat of my discharge?"
"It's completely insulated! I applied a top-tier thermal dampening coat along the exterior grip, but inside the shaft, I mapped a network of microscopic vacuum air ducts," Jeno snapped his fingers, his eyes whirring with technical enthusiasm. "The Flame-Flame Fruit cannot artificially alter the base temperature of an existing flame, correct? Pour your current into the steel now and check the output!"
With a thought, Sabo directed a sudden, compressed pulse of fire through his palm into the grip.
Boom!
The dark red alloy staff instantly shifted color, turning as blindingly radiant as an industrial branding iron. A millisecond later, the microscopic exhaust vents at both terminals of the shaft spewed two violent plasma jet streams, their color shifted to a deep, compressed dark blue due to the extreme structural restriction.
"I mapped that internal physical compression matrix to forcibly multiply the kinetic exit temperature of your fire," Jeno shouted excitedly over the hiss of the air. "The microsecond the steel registers contact with an enemy, the blue flame—compressed to its absolute limits—will trigger a high-density concussive explosion! Furthermore, because the core is infused with memory elements, even if you warp the frame while clashing with a tier-one powerhouse, the shaft will automatically return to its baseline geometry within seconds!"
Sabo's eyes flared with appreciation. He swung his shoulder, unleashing a casual, backhand stroke toward the open water far below. A column of dark blue fire, tightly wound into a spinning spiral trajectory, punched through the air with a heavy roar, detonating a massive wall of white water hundreds of meters away from the hull.
"Absolute explosive weight. With this, my path has added wings," Sabo said, smoothly anchoring the staff into the harness along his spine.
"And what's the ledger on my steel, cyborg? What are the metrics on this rod?" Enel asked, his current reaching down to drag the highly ornate conductive weapon directly into his palm.
"That configuration was engineered exclusively to complement your fruit's voltage," Jeno said, pointing toward the shaft. "Its molecular hardness and electrical throughput completely lap standard gold properties. Most importantly, I deliberately engineered a lower, specific melting point relative to high-frequency voltage. You can use it as a rigid, blunt weapon to crack armor, but the moment you spike your output, the metal will dissolve and reshape into a trident or any tactical geometry your will dictates—exactly like your old gold staff!"
Hearing the parameters, Enel spiked his current. The rod instantly softened within a blinding flash of blue static, translating smoothly into a razor-sharp lightning spear according to his mental focus before snapping back into the rigid form of a heavy pestle.
"Yahahaha! This is a weapon fit to command the upper air! Clean work, mechanical child!" Enel laughed boisterously, spinning the iron through a series of blinding rotations above the deck.
"As for Urouge's armaments, aside from extreme weight and structural density, it carries zero intricate features," Jeno remarked, gesturing toward a ridiculously thick, hexagonal black iron pillar resting near the rail. "It's built strictly to smash through physical durability. Of course, it shares the memory alloy trait, so the frame won't remain warped after an impact."
Watching the primary vanguard test their custom gear, Buggy—who had been lurking near the shadow of the superstructures—could no longer contain his agitation.
"Hey! Jeno! What about my account?! Don't tell me your forge only runs for the freaks on this ship!" Buggy scrambled over, locking his fingers around Jeno's shoulder.
"How can I neglect the assassin profile of the Star Clown?" Jeno grinned, pulling a sleek, matte-black case from his tool harness and pressing it into Buggy's arms. "I've compiled two specific assets for your inventory. Open the latches."
Buggy cleared the seals. Nestled within the foam were several custom micro-capsules alongside two vials of perfectly transparent liquid.
"Those fluid components remain entirely stable and inert when isolated," Jeno explained, his voice dropping into a quiet murmur. "But the microsecond they register mutual contact, they will trigger a high-intensity chemical detonation in less than three seconds. Take them and utilize your separation arrays to map out a few invisible traps."
Jeno leaned closer. "As for those capsules—they're packed with a highly volatile, weaponized neurogas. You can utilize your separation to affix these capsules together, navigating through an enemy's blind spot before popping the seals. It is completely colorless and devoid of scent; a single inhalation will paralyze the neural pathways of an apex giant beast for half an hour. A thoroughly venomous asset."
Neurogas? Chemical detonations?
Buggy's eyes lit up with instant malice as he stared down at the specialized tools. A villainous, low chuckle escaped his throat. "Yahahaha! Magnificent! This aligns perfectly with my preferences! With these assets in my coat, I'll be the most dangerous shadow operating along the shipping lines!"
While the layout on the main deck proceeded, a rhythmic, mechanical sound broke through the chatter.
Click... click... click...
Emerging from the wide shadows of the mid-deck cargo ramp was a dark, two-meter-tall mechanical spider. The futuristic construct featured a completely sealed, reinforced spherical cockpit mounted over its chassis, surrounded by an array of high-resolution external lenses.
Inside the pod, the instrumentation panels were fully lit. Bonney sat comfortably within a custom leather pilot's chair, her small hands locking around a pair of dual joysticks as she excitedly directed the mechanical spider to scramble across the iron plates.
"Target sighted! Deploy the legs! Crush the red-nosed uncle standing near the rail!" Bonney's cheerful, uninhibited voice boomed through the mech's external audio arrays.
"Whoa! Keep that multi-ton insect away from my segments!" Buggy shrieked, his torso instantly splitting away from his trousers to float out of the spider's path.
"Hahaha! Chopper, check the velocity on these servos!"
Bonney pivoted the machine, directing the spider to track alongside the ship doctor. Because her affliction prevented any direct interaction with natural sunlight, Jeno had worked through successive night shifts to construct this fully insulated, life-support armored shell, allowing the child to navigate the open deck plates without risking cellular degradation.
"Bonney, that rig is exceptional!" Chopper's eyes shone with pure excitement, his body transitioning into a compact, bouncy form as he scampered alongside the mechanical legs.
Since integrating the Limit Breaker serum, Chopper's command over his Zoan wavelengths had achieved a flawless baseline; he could now navigate through his seven transformational frequencies at will, completely free of the requirement for his old chemical stimulants.
The giant Kuma sat silently near the lip of the deck, his massive leather Bible resting in his lap. Tracking his daughter's uninhibited laughter echoing from the armored cockpit, a gentle, thoroughly human smile softened the rigid lines of his usually stone-cold face.
Meanwhile, along the wide, open-air arena at the absolute prow of the vessel:
Clang!
A deafening, metallic detonation ripped through the air currents, accompanied by a visible, dark red shockwave that rippled across the deck plates.
Ace, working shirtless with the Supreme Grade blade Ace held in a single-handed grip, was meeting the joint assault of Leona and Brook head-on through a series of savage, high-velocity exchanges.
Clang!
Ace delivered a brutal, short-arc backhand stroke, accurately deflecting the silent thrust of Brook's Soul Solid. Without pausing his momentum, he drove his hips forward, his blade swinging through an exaggerated semi-circle in the empty air before slamming his weight directly into the descending edge of Leona's greatsword.
Boom!
Two immense physical weights collided in mid-air. Leona felt a sharp, localized numbness lock her wrist, the sheer concussive impact of the blow forcing her boots to slide back several meters across the iron wood.
"The transition is still sloppy, Leona," Ace grinned, his fighting reflexes mirroring the raw, predictive nature of an apex predator. "Your gravity toggle was exactly half a second behind the swing. The downward trajectory of that greatsword was far too broadcasted; I don't even require the future path to read that line—my baseline instincts can anchor the parry."
"The Captain's style remains completely unreasonable," Leona remarked, rolling her numb wrist to restore circulation, though her vertical pupils were burning with intense excitement.
She recognized that Ace didn't utilize any refined, orthodox sword disciplines or elegant schools of fencing. His command of the blade was identical to the movements of an ancient, awakened beast—completely stripped of redundant flourishes. He relied entirely on his terrifying dynamic vision, explosive muscular power, and raw combat reflexes, utilizing a brutal, direct style to systematically crush whatever entered his line of fire. And this was while his fruit powers and Haki remained completely unactivated.
"Your velocity is pulling your center too far forward, Brook!"
Ace snapped his torso around, his sword precisely capturing a fleeting, ethereal blue afterimage amid the wind.
"Your underworld ice isn't engineered for direct, head-on structural collisions; utilize your speed metrics to cut into my absolute blind spots!"
"Yo-ho-ho... the Captain's clinical metrics are brutal. My old bones are on the verge of splintering under this strange physical force."
Despite the rattling complaint, the pale blue fire within Brook's empty sockets flared with a deeper intensity. The velocity of his thrusts spiked, the freezing underworld current leaving his edge mapping a thin layer of white frost along the deck plates as he attempted to bypass Ace's relentless defensive perimeter.
Three outlaws, each commanding entirely distinct sword philosophies, maintained a high-intensity exchange across the bow. Leona's fast, heavy dual-wield matrix was lethal; Brook's lightning-fast, unpredictable soul strikes were untraceable; yet Ace, relying on pure violence and animal intuition, tore a bloody path directly through the center of their configurations.
