The slashing attack erupted from the swirling smoke with zero warning. It was blindingly fast, carrying the heavy, lethal momentum of a strike meant to end the fight in a single motion.
Finn didn't even try to reach for his hip. The crushing gravity of his Devil Fruit violently yanked the Shindokuto from its scabbard, snapping the dark blade directly into his palm just as his fingers closed around the grip. With a sharp twist of his wrist, Finn pressed the steel downward, forcing the incoming slash off its fatal trajectory. The deflected blade sparked violently against his own, burying itself into the bedrock. The sheer kinetic force of the parry split the solid stone cleanly along the path of the strike, carving a smooth, smoking fissure several inches deep.
Around him, the rest of the surviving Five Elders launched their coordinated ambush at the exact same moment.
Saint Saturn wielding the walking stick slammed into Kuzan before the Admiral could even finish processing the frozen Pacifistas. One second Kuzan was standing casually. The next, the solid ice he had reflexively shifted into was shattered into a thousand glittering fragments, and the elder was already repositioning for another strike.
Saint Peter lunged at Gion. His hand snapped forward in a vicious claw grip, the skin turning pitch black as dense Armament Haki flooded his fingers. Gion read the attack in a fraction of a second and chose a brutal defense over evasion. Searing, high-voltage lightning flashed across her arm the instant before he grabbed her. The current surged through her skin, making the elder's hold physically possible to maintain, but excruciatingly painful. His grip held, but his jaw locked tight against the voltage.
Saint Mars materialized from the smoke and drove a brutal, open-handed strike directly into Sengoku's stomach. The blinding golden glow of the Buddha form flared to life a microsecond before impact, triggered entirely by decades of ingrained combat reflex rather than conscious thought. Sengoku absorbed the crushing blow. His expression tightened into a grimace, visibly working through the kinetic shock, but he remained firmly planted.
Sakazuki and Borsalino were entirely ignored.
The math was brutally simple. There were five elders and six Marine targets. The two most overwhelmingly destructive members of the vanguard had been deliberately left unengaged. The Elders had made a very specific, calculated decision about which fights they could survive, and which ones they absolutely couldn't.
Kuzan's shattered ice slowly reassembled itself. Cold, dense mist rolled off his shoulders, and his usually lazy expression had hardened into something that suggested he had taken the ambush deeply personally.
"So, everyone else just gets a little scrape, and I'm the one who actually gets knocked into pieces?" Kuzan exhaled a long, heavy breath that instantly froze the moisture in the air. "I would like to formally register a complaint."
"Save it," Finn said, his eyes locked dead ahead on the elder standing in front of him.
Saint Nusjuro stood at a measured distance. In his hand, he held the Shodai Kitetsu, the legendary First Generation cursed blade. The sword carried a dark, oppressive presence that even Finn—who possessed absolutely no spiritual sensitivity to cursed weapons—could feel humming in the air between them. The blade had vanished from public record over three hundred years ago. It had apparently been sitting in the vault of the Five Elders that entire time. Which meant whoever had originally claimed it had passed it down through generations of men who knew exactly what kind of monster they were holding.
"You old men really don't have to do this," Finn said, his tone conversational. "Your knees have already put in enough work for one day."
"The world has reached this catastrophic point because your Marine forces betrayed the sacred compact that has held civilization together for eight centuries," Saint Nusjuro replied. His voice was entirely level, carrying the flat, echoing certainty of a man who had made his final decision and had zero interest in debating it.
"Betrayed the compact," Finn repeated dryly. "Right. The compact where you all kneel on the floor to a woman sitting on a throne that is specifically, legally required to be empty. I must have missed that particular footnote in the World Government brochure."
"You are far too young to comprehend the delicate balance Lady Im has maintained."
"I'm forty," Finn sighed, a trace of genuine, exhausted fatigue bleeding into his voice. It was annoying how often he had to clarify this. "I just moisturize."
The elder didn't take the bait. He was carefully studying Finn, his eyes narrowing with the cold, calculating assessment of a master swordsman cataloging his opponent's stance and reach.
"That sword at your hip," the elder murmured, his eyes locking on the dark steel. "A demon blade, by the look of it."
"It's called the Shindokuto."
A flicker of genuine surprise crossed the elder's weathered face. "Donquixote's Shindokuto?"
"The very same."
"You think tossing out a dead man's name will shake my resolve." The elder sank into a lower, wider stance. He shifted his weight seamlessly, bringing the cursed Kitetsu up into a ready guard. "I have held this blade longer than your bloodline has existed. Empty words do not move me."
Finn opened his mouth to clarify that he wasn't trying to execute some grand psychological strategy; he was just making polite conversation. He closed his mouth a second later, deciding it wasn't worth the breath.
The elder moved.
His footwork was jarring. It was not the clumsy, predictable advance Finn had expected from a man who had spent the last three centuries sitting behind a desk stamping paperwork. The elder's steps were incredibly economical and deeply strange, creating overlapping, ghost-like afterimages that made it impossible to predict exactly where he would strike from. He had literally built shadows into his movement. The Kitetsu lashed out with the crushing weight of three hundred years of accumulated history behind it. The edge carried a terrifying sharpness that went far beyond what physical steel could achieve.
Finn was not a master swordsman. He had never once pretended to be. The masters who had trained him were generous with their praise, and the official Marine records were kinder still, but Finn knew the truth. His bladework was brutally functional, not elegant.
But what Finn was a master of was reading force.
The Press-Press Fruit had granted him an innate, microscopic sensitivity to vectors, gravity, and momentum. That awareness extended outward, allowing him to read the physical intent behind a blade before it even moved. He met every one of the elder's blistering attacks with complete, unshakeable reliability. The exchange of blows was rapid and deafening. Finn's parries were technically unremarkable but perfectly placed; the elder's strikes were technically flawless but ultimately useless.
"That blade," Finn noted calmly, speaking between the screaming clashes of steel. "The specific form you're using. That's Shimotsuki Isshin-ryu."
The elder's flawless rhythm broke for a fraction of a microsecond. "You recognize the style."
"A man named Koshiro runs a small dojo out in the East Blue. He's the current headmaster of that particular school." Finn deflected a lethal thrust aimed at his heart. "You're executing the forms correctly, for what it's worth. Your fundamentals are rock solid. It's just a damn shame about how you're choosing to apply them."
"Die," the elder hissed. It wasn't an insult. It was a physical shift in his killing intent.
The elder suddenly dropped low into an Iai stance. His weight shifted entirely forward, the Kitetsu sliding back into its scabbard with a sharp click. His entire body coiled like a massive spring around the single, devastating motion that was about to follow. His aura, which had been humming in the background like static, violently contracted into something dense, heavy, and needle-sharp.
Finn felt it instantly.
The concept of 'sword force' was real. Not every swordsman could manifest it, and those who could used it in vastly different ways, but the core principle was identical: it was the physical manifestation of pure willpower. It was an intent to kill so absolute and concentrated that it physically crossed the distance between fighters before the blade even cleared the scabbard, cutting the opponent's mind before the steel touched their flesh. Years from now, a young swordsman named Zoro would use this exact same principle to manifest the illusion of Asura. The demon trapped inside the Shindokuto had understood this truth for a very long time.
The sword cuts the flesh. The heart cuts the soul.
Finn didn't try to fight the oppressive force. He simply held it in his awareness, letting the heavy pressure wash over him without pushing back. He was genuinely curious. He had spent years fighting alongside the greatest swordsmen in the world without ever truly understanding the spiritual mechanics that separated the good from the legendary. The sensation was fascinating. He wanted to study it for just another second.
The elder misread Finn's absolute stillness. He thought the sword force had paralyzed him.
"Die!" The shout exploded from the elder's lungs as the Kitetsu vanished from its sheath.
The cursed blade tore upward in a blinding diagonal arc. The angle was flawlessly calculated to cleave Finn cleanly from his left shoulder straight through his neck. It was a perfect decapitation strike, refined by three centuries of obsessive practice.
It landed.
The elder felt the jarring vibration travel up his arms as the blade connected. It was real, physical contact. But the sensation was immediately wrong. There was no sickening give of parting flesh or shattering bone. The blade had bitten into something impossibly dense—something that had simply decided it was not going to be cut.
Conqueror's Haki wasn't meant to be visible. It was currently flowing through Finn's skin like a secondary skeleton, creating an absolute boundary between the surface of his body and the organs underneath. The legendary Kitetsu, backed by three hundred years of mastery and cursed sharpness, slammed into that invisible wall and stopped dead.
Just to be absolutely certain, Finn had also layered the Six Powers 'Iron Body' technique underneath the Haki. He hadn't actually needed it. But the elder had demonstrated terrifying power when he ambushed the Pacifistas earlier, and Finn preferred to over-prepare.
"Is that it?" Finn asked quietly.
He calmly reached up with his free hand and clamped his fingers around the razor-sharp edge of the Kitetsu.
The elder snarled and violently yanked the hilt. The blade didn't move a single millimeter.
"You've been sitting in an office chair for way too long," Finn said, his voice dropping into a cold register. "And this technique deserves vastly better than what you're using it for. The Shimotsuki school wasn't built to protect tyrants."
The elder stared in absolute horror at the bare hand gripping his cursed sword.
Slowly, his eyes tracked upward to meet Finn's face.
The whites of Finn's eyes were entirely gone. The pure, suffocating void of the Dark-Dark Fruit had risen up from within him, flooding his eyes until they were completely black from edge to edge. It wasn't just a dark color; it was the absolute, terrifying absence of light. A crushing, physical weight expanded outward from that hollow gaze, carrying no sound and generating no wind, but flattening the air around them.
The elder's body simply stopped cooperating.
It wasn't a physical bind. It wasn't gravity pinning him down. It was something far more fundamental. The absolute willpower that had driven the elder for three centuries—the exact same unshakeable resolve that had manifested his sword force just moments ago—slammed headfirst into Finn's will. And the elder's will broke. Whitebeard had called that overwhelming presence 'invincibility.' Gol D. Roger had called it 'freedom.' They were just different words for the exact same terrifying truth about what a human being could become if they lived long enough and believed hard enough in their own absolute power.
Finn looked at the paralyzed elder.
"Die," Finn said quietly.
The darkness violently erupted from the ground beneath the elder's feet.
The thousands of tons of shattered rubble and broken Pacifista parts that Finn had swallowed into his void earlier came screaming back out into reality. The debris didn't scatter. It materialized in a perfect, tightening sphere around the elder, driven by the exact same gravity-enhanced compression strike that had effortlessly erased the God's Abode's defensive wall.
Then, Finn clenched his fist. The sphere violently contracted inward.
The sound that followed wasn't a loud explosion. It was the sickening, wet crunch of something being subjected to unimaginable pressure from every conceivable angle at the exact same time. The sound didn't last very long, because the man making it ceased to exist almost instantly.
A thick pool of dark blood slowly seeped out from beneath the compressed sphere of rubble, pooling onto the cleared red bedrock.
Saint Nusjuro was gone.
Finn stood in the silence, looking down at the Shodai Kitetsu still resting in his hand. He slowly turned the hilt, feeling the heavy, unnatural balance of the weapon. He could feel three hundred years of accumulated malice and ill intent humming through the steel like a live electrical current.
He carefully set the cursed sword aside on a flat rock. It was a magnificent weapon, and it deserved far better handling than the current situation allowed.
