The night sky above Mount Kōzuki was fractured by scarlet lightning. Each bolt ripped open the darkness like a tearing wound, casting the jagged peaks in an otherworldly glow. Yuki stood at the cliff's edge, his silver hair whipped by the storm, golden eyes alight with quiet resolve.
From the pulsing rift in the sky descended a figure draped in ebony armor—Madara Uchiha, the Moon-Eyed God reborn. His Rinnegan eyes scanned the landscape, absorbing every detail. Cloaked in the echo of ancient chakra, he regarded Yuki with both curiosity and contempt.
"You," Madara's voice rolled like distant thunder, "are no ordinary spirit."
Yuki's hand hovered at his side, fingertips brushing the hilt of his blade—a weapon forged from his own void aura. "I'm not a spirit," he answered softly. "I am the void itself."
With that declaration, the air around Yuki quivered. Black tendrils of void seeped from his pores, intertwining with the storm's energy. Madara's lips curled into a faint smirk.
"Then let us see whether your nothingness can snuff out my everything."
...
First Clash...
Madara summoned a sphere of Truth-Seeking Orbs behind him, the orbs coalescing into a jagged blade of pure nothingness. Yuki braced himself, his aura flaring violet-white as he met the attack head-on. The impact shattered the ground beneath, sending shockwaves through the mountain.
Madara advanced through the crumbling earth, lead by his Perfect Susanoo's sword and shield. Every swing left craters, every step fractured reality. Yet when the Susanoo's blade struck Yuki's aura shield, a ripple passed through Madara's chakra, as if his blade had grazed a mirror.
He paused, narrowing his gaze. "You absorb chakra."
Yuki's wind-torn cloak hung limp. "Not just chakra—reality."
The Tide Turns...
Madara tapped into his Limbo: two invisible clones paralleled him, ready to strike from an unseen dimension. He lunged; the clones materialized, axes of shadow slicing toward Yuki's sides.
But Yuki didn't evade—instead, he swallowed them. His outstretched hand opened a black maw of void that devoured the clones mid-attack. Madara staggered at the sight, his Susanoo flickering.
"You can see Limbo," Yuki whispered, voice echoing with cosmic depth. "And you can end it."
Yuki hurled a torrent of void energy. Madara countered with a meteor of black chakra from his Rinnegan's Planetary Devastation. Sky met void in a collision that turned night into blinding light. When the flash subsided, both stood firm—Madara with his cloak singed, Yuki with hair singed white.
Heart of the Battle...
Madara's expression grew serious. He raised a hand, sealing the meteor's crater with a simple Rinnegan gesture. "You strike hard, but your void is unstable." He summoned Truth-Seeking Orbs into a ring around himself. "Let me show you balance."
Suddenly, the orbs lunged outward like a swarm of black lightning. Each orb carved the air with reality-erasing intent. Yuki's aura shield dissolved under the onslaught, forcing him to dive behind a stone spire.
Clutching his side, Yuki felt rage ignite his spirit. Memories of his fractured past, of the bonds he'd fought to protect, surged through him. His eyes flared—void bled into reality. The spire melted into inky mist as Yuki reclaimed the battlefield.
He roared, voice magnified by the void: "I will not be erased!"
From the center of his chest burst a massive void serpent, coiling around the orbs and grinding them into nothingness. Madara's Susanoo shattered under the serpent's crushing force, and he tumbled through the air.
The Final Gambit...
Madara landed on his feet, face streaked with sweat and blood. He wiped a drop from his cheek, offering a wry bow. "Impressive. But raw emotion makes you predictable." He activated the God Tree, roots bursting from the earth to ensnare Yuki.
As the colossal boughs writhed toward him, Yuki closed his eyes. The world stilled. When he opened them, he stood before Madara, unbound. "Prediction is just a pattern," Yuki said, "and patterns can be rewritten."
He reached out, fingertips glowing, and pressed them to Madara's chest. A pulse of void energy surged into the Uchiha, severing his connection to the God Tree. The roots withered; Madara fell to one knee.
Silence reigned. The storm had spent its fury, leaving only the clash of two destinies.
Madara looked up, eyes humbled. "You are not nothing."
Yuki withdrew his hand, voice calm as dawn. "I am everything you cannot control."
He turned and walked away, leaving Madara to contemplate the void that had conquered the Moon-Eyed God.
