At first, it was nothing — a whisper beneath the endless lull of the tide. A faint quiver that rippled through the flagstones of Marineford Bay, so subtle it might have gone unnoticed by every man stationed there. Every marine, except Sengoku.
The Fleet Admiral stopped mid-step. His brow furrowed. His boots pressed lightly into the stone as he tilted his head, feeling the world breathe beneath him. It was faint — impossibly faint — yet unmistakable. The kind of vibration that doesn't simply move through the ground, but inside it.
His eyes narrowed behind his glasses. Years of battle, decades of mastering Kenbunshoku Haki, and a lifetime of experience manipulating shockwaves had sharpened his senses beyond human. Where others felt calm, Sengoku felt the sea itself twitch.
Then, it hit him.
The realization clawed its way up his spine — cold, absolute, inevitable. His heartbeat quickened. His pupils constricted. The faint tremor pulsing beneath his boots wasn't a fluke of tide or wind. It was resonance — a low, distant echo of the power that could only belong to one man.
"Impossible…" he muttered, barely above a whisper. But even saying it made his chest tighten.
His mind raced through scenarios faster than breath. The direction… the rhythm of the vibration… the sheer magnitude hidden beneath that deceptive calm. He turned sharply toward the horizon, his gaze slicing across the bay.
Northwest. That was where it came from. That was the direction where the gates of justice lay. His face paled slightly — not from fear, but from grim understanding. He knew what that direction meant. What it had to mean. His breath steadied as he took one decisive step forward.
"Drop the anchors!" his voice erupted across the pier like a thunderclap, laced with urgency. "Cut them down if you have to — before the wave hits! Deploy all ships away from the coast…!"
Every Marine within earshot froze. Officers looked up from their posts, bewildered. Sailors paused mid-task, ropes slack in their hands. Even the dockmasters blinked in confusion.
"W-wave…?" one ensign stammered. "But, sir— the sea's calm!"
And it was — deceptively so. The waters of Marineford Bay shimmered like glass, the midday sun painting them gold. There wasn't a hint of wind. The world looked peaceful. But Sengoku knew better. He'd seen calm seas hide death before.
He tore his Fleet Admiral's coat from his shoulders and threw it aside, the fabric fluttering in the breeze like a discarded flag. In a single, powerful motion, he leapt down the steps toward the edge of the bay. The stone beneath his feet thrummed faintly — a pulse now growing stronger, deeper.
The officers exchanged anxious glances. Some hesitated. Others, trusting instinct, began shouting orders. Chains rattled, metal screamed as anchors ground against their winches, and the sails fluttered, pushing the massive battleships away from the bay. And then the first sound came.
A groan — low and distant, like the cry of the earth itself. It built upon itself, swelling, deepening, rolling through the sea until the calm surface began to shudder. The wind died entirely. The gulls vanished. Then Sengoku saw it. The entirety of Marineford saw it.
Far beyond the horizon, where sky and sea should have kissed in gentle stillness, the line of the world rose. Slowly, impossibly, the ocean began to climb — a dark, shifting wall that stretched across the entire horizon. And behind it came another. And another.
Each wave towered higher than the last — hundreds of meters tall, surging with unstoppable force. The sunlight bent against them, turning the crests into glimmering blades of silver that swallowed the sky. For a brief moment, time stood still.
The Marines at the bay stared, wide-eyed, disbelieving. Their minds refused to process what they saw. Then, reality hit.
A shrill WAAAAAAH! tore through the air — the tsunami alarm, screaming across every inch of Marineford. Sirens blared from the watchtowers; red lights began to flash across the harbor.
"Tsunami detected!" a voice shouted over the loudspeakers, cracking with static. "Incoming wave! All ships secure—!"
The rest of the message drowned beneath the roar of the ocean. The bay erupted into chaos. Sailors ran across gangplanks, shouting orders and hauling lines. Chains clanged as anchors dropped. Some ships had already begun cutting their moorings, blades flashing as they sliced through ropes to let the vessels drift freely.
Others weren't as lucky. Several warships still struggled mid-process — half-anchored, half-loose — when the tide began to heave. The water tilted, dragging the colossal vessels sideways, metal hulls groaning in protest. One frigate snapped its chain too late, the anchor wrenching through the deck and taking a dozen sailors with it as it plunged into the deep.
The sea was no longer flat — it was breathing, tilting, heaving in unnatural rhythm. The ocean itself had turned into a living weapon. From his place at the bay's edge, Sengoku watched in grim silence, the wind whipping his hair as the first of the monstrous waves came fully into view. His jaw tightened, his hands curling into fists.
"NEWGATE…" he screamed under his breath. "You insane old BASTARD…"
The air pressure changed — a rushing vacuum preceding the tsunami's rise. It was not merely water anymore; it was the weight of the world, a force capable of swallowing islands whole. Behind him, the Marines shouted — orders, prayers, screams — all lost beneath the rumble that devoured sound itself. The sky darkened, the sun blotted out by the sheer scale of the wall bearing down on them.
And still Sengoku stood firm, his eyes hard as gold beneath his cap. His instincts screamed to prepare for battle, yet his mind whispered of futility. This was not a fight of men and weapons. This was the wrath of a god. The waves crashed closer — enormous, relentless, divine.
"Brace for impact!" someone yelled.
The horizon was gone — replaced by a churning wall of death that blotted out the sky. The first of the waves rose like a mountain of liquid glass, its shadow stretching over Marineford Bay. The sunlight fractured across its crest, splitting into ribbons of gold and blue before collapsing inward under its own impossible weight. The tsunami had arrived.
Sengoku's gaze locked onto it — steady, unflinching. His golden epaulets fluttered wildly against the storm winds. Around him, the Marines scrambled in terror, their formations breaking apart, their shouts lost to the monstrous rumble. Ships capsized. The docks splintered. The sea itself was rebelling against the world.
The entire marineford could sense it clearly now — the resonance deep within the tremor. That unnatural rhythm. There was no doubt. Only one man could be responsible for this chaos.
Whitebeard.
A god had struck the ocean, and now the ocean had answered in kind. Sengoku closed his eyes briefly, drawing a long breath through his nose. He could smell the salt, the iron, the fear. He could feel the weight of tens of thousands of Marines — men and women who looked to him for salvation — pressing down on his shoulders. There was no room for hesitation, not if he wanted to protect Marineford and its inhabitants.
"All hands, fall back to the inner docks!" he roared, his voice carrying like thunder. "Now! Leave the sea to me!"
The command cut through the panic. Marines obeyed on instinct — retreating, stumbling over themselves as they scrambled for cover. The last of the ships pulled hard on their rudders, pushing desperately toward the far edges of the harbor.
And Sengoku… He stepped forward. His boots touched the trembling edge of the pier, and the air around him began to hum. A low, resonant vibration rolled through the bay — not from the sea, but from within him.
Golden light bloomed along his arms, crawling up his veins like molten fire. His skin shimmered, his body expanding, his frame stretching and widening until the air itself bent around his form. The ground beneath his feet cracked and cratered under the sudden surge of energy.
In the next instant, the world exploded in light. A pillar of radiant gold erupted from the bay, piercing through the storm clouds. The blinding brilliance forced every Marine to shield their eyes as the Fleet Admiral ascended, transformed — his body becoming a colossal, divine figure of pure golden might.
Where Sengoku had stood now towered a Guanyin Bodhisattva, vast as the mountains, luminous and terrible. His thousand arms unfolded like the petals of a cosmic lotus, each hand shimmering with inscriptions of ancient justice. A vast halo of golden sashes spiraled behind him, rippling through the rain and wind like banners of divine judgment.
Sengoku opened his eyes — twin suns burning through the haze — and spoke with a voice that seemed to echo across heaven and sea alike:
"Kōsei: Senju Kannon..!"
The storm froze for a heartbeat. Then, with a single motion, the Buddha moved. A thousand golden palms surged outward, spreading across the bay like a luminous wall. The air shook with the vibration of pure force — not from impact, but from intent and the raw power of armament haki emission. Each hand struck the sea, the very air rippling around them as they met the oncoming wave head-on.
BOOOOOOOM!!!
The collision was apocalyptic. The first tsunami met the golden wall and split apart, bursting into a storm of white mist and thunderous spray. The shockwave flattened entire ships, shattered docks, and sent a ring of vapor racing across Marineford. But before the water could settle, the second wave was already rising behind it — taller, darker, more furious.
Sengoku's expression hardened. The seawater was suppressing his Devil Fruit's spiritual field; the dense salinity gnawed at his strength. The radiant glow of his golden skin began to flicker faintly, his massive frame steaming as the cold ocean assaulted his very essence. But he didn't yield.
He crossed his hands, his thousand arms mirroring the motion, forming a grand mudra — the seal of divine guardianship. A colossal golden mandala manifested across the horizon, spinning like a wheel of heaven itself. Its patterns glowed with symbols of truth and law as Sengoku thrust his hands forward again.
The mandala expanded — a radiant barrier crashing against the second wave. The ocean screamed. The world itself seemed to bend as divine light and natural fury collided. The second wave shattered.
But the third — the largest of them all — was already upon him. It blotted out the sun completely, a moving mountain of water carrying the remnants of Whitebeard's unleashed wrath. Its shadow fell over Marineford, darkening everything beneath it.
Sengoku staggered, his massive heel sinking into the breaking pier, his immense form trembling under the strain. His golden aura sputtered — but he didn't stop.
"I am Sengoku… the Golden Buddha!" he roared, his voice booming through the storm. "And while I yet breathe, Marineford will not fall!"
His thousand arms spread once more — but this time they merged, converging into one singular, massive golden palm that dwarfed the fortress itself. It rose high, veins of lightning dancing across its surface, the very air vibrating from the force. The palm descended.
"Supreme Technique — Daihōrin: The Wheel of Ten Thousand Truths!"
The golden hand struck the sea. The impact split the world. A dome of golden light erupted outward, meeting the tsunami in full. The colossal wall of water disintegrated upon contact, breaking into trillions of droplets that caught the sunlight like falling stars. The shockwave carved deep trenches into the sea floor, sending waves racing in every direction — away from Marineford.
For a long moment, there was silence. Then, slowly, the light began to fade. The sea, though still wild, began to calm. The sky broke open, revealing shards of blue through the clouds. Sengoku knelt at the edge of the shattered pier, his immense golden body steaming, cracks running through the armor of light. His breathing was heavy, but his eyes burned with resolve.
Behind him, the Marines — those who had survived the onslaught — stood frozen in awe. Some fell to their knees. Others stared wordlessly at the divine figure that had just held back the wrath of nature itself. To them, Sengoku wasn't merely a man. He was Kannon, the thousand-armed protector. The guardian god of Marineford.
The Fleet Admiral slowly rose again, his gaze turning toward the far horizon — where, beyond the mist, he knew the architect of this destruction waited.
"Whitebeard…" he whispered, voice cold as steel and heavy as judgment. "You've declared war upon the world again. Then come — and face its guardian."
****
The sky split with thunder. Three figures streaked across the open sea like bolts of divine lightning, their white Marine coats whipping behind them, glinting with sunlight as they tore through the air. Each step cracked the very sky.
Two of them—veterans, disciplined shadows — used Geppo, the Moonwalk, propelling themselves forward in a relentless rhythm that shattered the sound barrier again and again. Their boots struck the air, leaving faint ripples that dissipated into mist, their pace unbroken even as miles vanished beneath them.
But the third — the man following close behind — didn't use air alone. Wherever his foot fell, the sea itself froze. Columns of ice bloomed into existence, one after another, forming fleeting footholds that exploded into shards under the pressure of his next step. That was Admiral Kuzan, the Blue Pheasant, and he was barely keeping up.
The three Marines cut through the skies above the New World with such speed that passing storm clouds were left spinning in their wake. The sun dipped and rose again before they even slowed. Hours blurred into a day, and still they ran — unceasing, unstoppable, their bodies screaming under the strain of momentum itself.
And at last — after a full day of movement so fast that even light seemed to lag behind them — it appeared. The Red Line.
A colossal wall of living stone that split the world itself — rising from the depths of the ocean and piercing the heavens like a divine blade. The ancient scar of the planet, crimson and black, its surface glowed faintly in the evening light. From horizon to horizon, it stretched endlessly — a monument to the gods that shaped the world.
As they approached, the three Marines finally began to slow, their silhouettes streaking through the clouds before landing upon a narrow stone ridge overlooking the sea. The air shimmered with heat and exhaustion.
Kuzan exhaled heavily, a faint frost escaping his breath as he landed, knees bending slightly to absorb the impact. He was calm, but his chest rose and fell in sharp rhythm — a rare sight from the normally lazy admiral. The salt wind stung against his sweat-slicked skin, the ache of relentless motion pulsing through his limbs.
He'd fought wars nonstop for days , frozen seas, and battled Yonko — but this? This was different. It wasn't battle fatigue. It was the exhaustion of trying to chase legends. Kuzan's eyes flicked sideways toward the man standing a few meters ahead of him.
Bogard.
The silent shadow of the Hero. His uniform was torn at the shoulders, his breath heavy but measured — far steadier than Kuzan's. A sheen of sweat clung to his brow, but his posture remained perfect, his hand resting easily on the hilt of his blade. Even now, there was no sign of collapse, no hint of weakness.
It was infuriating — and inspiring. Bogard was no Devil Fruit user. No Admiral. No monster of natural ability. He was human — disciplined, hardened, molded into perfection through decades of battle and iron will. But even then, compared to the man at the front…
Compared to Monkey D. Garp… He was mortal.
Garp stood at the very edge of the cliff, arms crossed, his back straight, his chest broad. His cape rippled like a battle flag, catching the light of the noon sun. He wasn't panting. Not even breathing hard. His muscles were carved like granite, his fists still clenched tight, ready for war. He looked as though he had just begun warming up.
The sea breeze howled, carrying the scent of salt and iron. Garp's gaze was fixed on the Red Line ahead — and the invisible path that would take them to Marineford, to the heart of the storm. For a moment, the only sound was the distant rumble of waves crashing against the Red Line's roots.
Then, with a deep, booming laugh that echoed like a cannon, Garp spoke.
"Bwahahahaha! What's the matter, you two? Don't tell me you're winded already!"
Kuzan blinked, speechless for a heartbeat. "Winded…? Garp-san, we've been running nonstop for twenty-four hours through open sky. Even I'm starting to—"
"Bah!" Garp barked, waving a hand dismissively. "You kids these days are soft. Back in my time, we used to run three days straight just to get breakfast!"
The Red Line loomed before them like an unconquerable titan, an impossible wall of red stone that divided the very world. Bogard's voice broke through the roar of the wind.
"Garp-san... Kuzan is right; if we continue like this, we may not be in shape to fight once we reach Water 7..."
He wasn't wrong. His voice was steady but edged with concern — not for Kuzan, not even for himself, but for Garp and for what he knew was coming.
Bogard had been by Garp's side longer than anyone alive. He had seen the Marine hero in his youth — laughing amidst cannonfire, crushing pirate fleets with his bare hands, and standing tall on battlefields littered with legends. But he had also seen the other side — the man behind the laughter, the one who still carried the ghosts of God Valley deep in his eyes.
And now, as the winds howled around them, Bogard could sense that same storm brewing again.
The entire world's shadow loomed over Water 7. The world teetered on the edge of catastrophe, a repeat of what happened decades ago. And though Garp's laughter still boomed through the skies, Bogard could feel the rage simmering beneath it — hot and quiet, like magma beneath stone.
Garp slowed for a heartbeat, the air cracking around him as his boots struck the small patch on the base of red line where it met the sea. His weathered face turned toward Bogard, and for once, his grin faded — replaced by something softer.
A silent nod. He understood. Garp could run for days, fight for nights, shatter mountains, and still stand tall. But his men — needed their strength for what awaited them. And as reckless as he was, the Hero of the Marines would never burn out his own before the real battle began.
"Fine then..." he muttered, the wind tugging at his words. Then, with that same booming certainty that could shake fleets apart, he grinned again — wide, wild, and terrifying.
"You both better hang on."
Bogard blinked. Kuzan frowned. "Wait, hang—?"
Before either could react, Garp moved. In a blur faster than thought, his massive hands shot out — one clamping around Bogard's collar, the other snagging Kuzan by the back of his coat like they were a pair of misbehaving recruits.
"OI—GA—GA—GA—GAR—P-SAAAN!!" Kuzan barely managed to shout before the world inverted.
With a single flex of his legs, Garp launched himself straight upward, the air beneath them detonating like a bomb. A sonic boom shattered the clouds as they rocketed skyward, the ocean below shrinking into a distant blur.
Kuzan's eyes went wide behind his sunglasses, his limbs flailing uselessly. "WHAT THE—! This isn't even—!! WE'RE SUPPOSED TO CLIMB—!!"
Bogard, on the other hand, didn't struggle. His coat whipped violently in the gale as they soared past the lower cliffs, but he merely sighed — resigned, composed, and utterly unsurprised. He'd known this was coming. He'd always known.
When Garp said "hang on," there was never a metaphor involved.
"You'll get used to it, Kuzan," Bogard said dryly, hair snapping in the wind as they ascended.
"First time's always the worst."
"THE WHAT—?!" Kuzan shouted as Garp's laughter roared through the heavens.
"BWAHAHAHAHAHAHA! THIS'LL SAVE US SOME TIME, WON'T IT?!"
The air screamed around them. With every kick, Garp leapt hundreds of meters, each impact shaking the Red Line itself. Chunks of red rock tumbled away as if the very world was making way for him.
Ten meters. A hundred. A thousand. He didn't slow. Each stride was like a cannon shot, the atmosphere bursting into rings of white vapor around him. The ocean below churned violently in their wake, waves collapsing from the sheer force of his ascent.
"Old man—! The altitude—! I can't—!" Kuzan sputtered, his words tearing away in the wind.
"Stop whining!" Garp bellowed, his grin splitting his face. "If you can't breathe up here, you're not ready for the monsters below!"
Bogard chuckled quietly, his hand gripping Garp's arm with practiced ease. "It's useless, Kuzan. You can't argue with him when he's in this mood."
The Admiral looked at Bogard incredulously. "How are you this calm?!"
"Decades of experience," Bogard said flatly. "And acceptance."
With that, the world turned blinding white. The trio broke through the clouds, bursting into the open heavens above the Red Line. The sun hit them full on — a golden blaze painting the sky in crimson and fire. Far below, the oceans glittered like glass; far ahead, the faint outline of the first half of the Grand Line shimmered in the distance — and beyond that, Water 7, where chaos was already brewing.
Garp finally slowed, his boots finding purchase on the sheer vertical wall of stone at the very top of the desolate redline. He landed with a thunderous boom, standing upright as though gravity itself dared not challenge him. Kuzan dangled limply from one hand, pale and disheveled.
"Next time," Kuzan muttered weakly, "I'm scaling on my own..."
"Bwahahahaha!" Garp's laughter rolled like thunder. "What's the matter, Admiral? Don't tell me a little climb like that's too much for you?"
Kuzan groaned, rubbing his temple. "Little climb? You scaled the entire Red Line like a staircase!"
"Exactly!" Garp beamed proudly, dropping both men to their feet. "See? This way you'd conserve your strength. Now you'll be fresh for the fight once we reach water 7!"
