The air of the battlefield was heavy, reeking of smoke, steel, and blood. Every step sank into mud darkened not only by rain but by the countless shinobi who had fallen over the months of endless war. The land itself felt broken, its veins carved by kunai, scorched by katon, frozen by hyōton. A world that had screamed for peace was drowning in violence.
Ryuzen stood at the center of it. His chest heaved as he pulled his blade from the final Iwagakure jōnin who had dared to charge. His system window flickered at the corner of his vision, glowing ominously.

A silence fell for the briefest of moments. The battlefield felt paused, as if the world itself recognized that history was on the edge of breaking.
Behind him, Might Duy staggered, his muscles trembling from sustaining the Seventh Gate far longer than humanly possible. His sweat and blood painted the ground beneath him, but his eyes blazed. "Ryuzen… finish it. End this war. Protect Konoha."
Minato landed beside them, his golden hair spattered with blood, his cloak torn at the edges. Even the Yellow Flash looked heavier than usual, burdened by the weight of hundreds of lives entrusted to his speed. His sharp eyes scanned the field, then settled on Ryuzen. "This is it. One push. Kannabi Bridge must fall tonight, or Konoha will never recover."
The Mission That Would Shatter Legends
Kakashi adjusted the forehead protector over his newly gained Sharingan, Obito's gift still burning his nerves. His breaths came ragged, grief weighing heavier than his wounds. Rin lingered behind him, her hands shaking with the blood she could not wash from her gloves.
The team was fractured, scarred, yet they stood at the precipice of legend.
The Kannabi Bridge loomed ahead—its massive supports groaning under the strain of the river's current. Destroying it would sever Iwagakure's supply lines, strangling their offensive once and for all. But between them and the bridge stood an army—battle-hardened stone shinobi, refusing to yield their foothold.
Minato's kunai gleamed as he marked the air, his formula spreading across the battlefield like threads of destiny. "Ryuzen. You take the center. Leave the rest to me."
The Collapse Begins
The first explosion shook the ground as Minato vanished, reappearing in flashes of gold, striking down squads of Iwa-nin before they even registered his presence. His movements weren't just fast—they were divine. The Yellow Flash was no longer a man but the embodiment of inevitability.
But it was Ryuzen who turned inevitability into terror.
His chakra surged, violent and unrestrained, his blade glowing crimson under the moonlight. He moved like a storm given form, each swing cleaving through multiple shinobi. His system pulsed with every kill, numbers climbing, the interface trembling as if struggling to contain his power.

And then it happened.
The ground erupted near Kakashi, stones splitting apart as Obito's crushed form struggled beneath the rubble. His voice, broken but unyielding, called out to them. "Take care of Rin… Kakashi. My eyes… will see the future with you."
Kakashi's hands trembled as he covered his left eye, tears mingling with blood. Rin screamed, her voice ripping through the chaos.
And then silence. Obito's chakra flickered out, buried beneath the collapse.
Ryuzen's Thousandth Kill
The rage that followed wasn't human.
Ryuzen's eyes burned with fury, his body shaking as the system recognized the shattering of his control. The Iwa-nin who had triggered the collapse tried to flee, but Ryuzen was upon him in less than a heartbeat. His blade sank deep, carving through armor, flesh, and bone.
The system's voice roared in his mind.

[Warning: Host synchronization with Obsidian Path initiated…]
His chakra burst outward, black flames laced with violet sparks tearing through the battlefield. Shinobi stumbled back in horror as Ryuzen's presence expanded, eclipsing even Minato's brilliance. The air grew heavy, suffocating, as if shadows themselves bent to his will.
Minato's eyes narrowed. "Ryuzen…" He could feel it—the shift, the dangerous thread of power not born of chakra alone. Something older, darker, watching through Ryuzen's soul.
The Bridge Falls
The final charge began. Ryuzen cut through Iwa's elite like parchment, his every strike a blur of black flame and steel. Kakashi, fueled by grief, followed at his side, the Sharingan guiding his strikes with deadly precision.
Together, they carved a path straight to the bridge's support beams. Explosive tags were placed, chakra surged, and the ground shook with each detonation.
The Kannabi Bridge groaned like a dying beast before collapsing into the roaring river, its remains swallowed by the current. Iwa's forces, cut off, scattered in desperation.
Minato's kunai flashed one last time, his presence sealing Konoha's victory. The Third Shinobi War ended not with treaties or words—but with blood, sacrifice, and legends etched into eternity.
Aftermath
Smoke curled into the sky, carrying with it the whispers of the fallen.
Kakashi sat in silence, his new Sharingan spinning faintly, his heart hollow. Rin wept softly beside him, the weight of Obito's death carving scars deeper than any wound.
Duy collapsed to one knee, finally releasing the Seventh Gate. His body screamed in agony, but his smile was serene. He had lived. He had protected. His promise to Guy remained intact.
And Ryuzen…
He stood at the edge of the ruined bridge, his blade dripping with the thousand lives he had claimed. The system's glow lingered faintly in his eyes, the shadow of the Obsidian Path whispering promises of power yet to come.

[Warning: Host has drawn the gaze of forces beyond the shinobi world]
Minato approached slowly, his expression unreadable. "You've done what no one else could, Ryuzen. But remember—sometimes victory demands a heavier price than defeat."
Ryuzen said nothing. The blood on his hands was heavier than any medal, any recognition. And deep within his system, something ancient stirred.
The war was over.
But Ryuzen's true battle had just begun.
🔥 Author's Note:
And that, readers, is the end of the Third Shinobi War Arc! 🎉
Kannabi Bridge has collapsed.
Obito's "death" has happened.
Kakashi's legend is born.
Minato shines as the Yellow Flash.
And Ryuzen? He's crossed 1000 kills and awakened the Obsidian Reaper title — a dangerous evolution of his system that will echo through the story.
From here, the tone shifts: no longer survival in war, but the shadows creeping behind Ryuzen's system… and what "Obsidian" truly is.
