While the legendary trinity of Luffy, Goku, and Naruto lay anchored in a deep, restorative coma, the winds of anxiety over "Aquatic Konoha" grew into a tempest. The golden fractures in the sky had begun to "bleed"—shedding a fine, crystalline dust known as Ethereal Fallout. This dust acted as a universal suppressant, short-circuiting electronic Saiyan tech and destabilizing standard Ninjutsu. The need to repair the shattered Dragon Balls had moved from a strategic goal to an absolute necessity for survival.
"The material we need is known as Molten Chrome-Saiyan," Piccolo stated, his voice gravelly as he unrolled an ancient, scorched parchment before Zoro, Sasuke, and Vegeta. "It is a substance that only exists in the pressurized womb of Mount Subaru—a peak birthed from the violent collision of the floating island Onigashima and a secret Saiyan research facility. Without this metal, the Dragon Balls will simply vaporize under the heat of Six Paths Chakra."
Vegeta stared at the distant, jagged peak that loomed on the horizon, shrouded in plumes of violet volcanic smoke. "I know of that place," the Prince muttered, his eyes narrowing. "The scent of death lingered there even before the merger. I will go—not for the sake of your 'peace,' but because I refuse to live in a universe as fragile as cheap glass."
Zoro, who had been methodically whetting the edge of Enma, stood in silence. He sheathed his blade with a resonant click. "A volcanic fortress? Sounds like a suitable whetstone for my new blades. Let's see if Saiyan stone can withstand the breath of a demon."
Sasuke adjusted his tattered cloak, his lone Rinnegan shimmering with cold calculation. "Then move. Time is a luxury we no longer possess, and the shadow I felt in the depths... it's no longer stationary."
The Path to Subaru: Hybrid Abominations
The trio moved through the "Mutant Wastes"—forests where the trees had developed metallic bark and leaves as sharp as kunai. The wildlife had suffered an even grimmer transformation. They were soon intercepted by a pack of Ninja-Wolves, creatures with reptilian scales that emitted low-frequency "Ki-growls" from their throats.
"Don't break your stride!" Sasuke commanded. He didn't even look at the beasts, simply weaving a sign that ignited a wall of Amaterasu. The black flames consumed the vanguard of the pack, but the creatures were relentless, leaping through the fire with reinforced Saiyan-hide.
Zoro pivoted in a blur of motion. "One-Sword Style: Song of the Lion!" (Shishi Sonson). His draw was so fast the air itself seemed to scream. The blade left a wake of black Armament Haki that didn't just cut—it severed the creatures' ability to regenerate, leaving five of them halved in the dust.
Above them, Vegeta was a streak of violet light. He didn't bother with fancy techniques, instead firing pinpoint Ki blasts that detonated the wolves' heads before they could leap. "How pathetic! Are we going to spend the entire afternoon playing with dogs? Move faster, you snails!"
The Core: The Forsaken Saiyan Foundry
They finally reached the yawning caldera of Mount Subaru. Inside, they found no ordinary magma. The crater housed a gargantuan Thermal Reactor fueled by a mixture of terrestrial lava and the concentrated energy of a "Star-Meteor" that had once struck Planet Vegeta.
In the center of the reactor, glowing with a pulsating sapphire light, sat the ingots of Chrome-Saiyan. But the treasure was not unguarded.
"Halt, intruders," a cold, mechanical voice echoed from the depths of the foundry.
Out of the steam stepped dozens of Pacifistas, but these were models unlike any the world had seen. They were encased in heavy Saiyan combat-armor, their eyes fitted with synthetic, glowing Sharingan lenses, and in their hands, they ignited humming energy-blades.
"The Metal-Guardians..." Sasuke whispered, manifesting a skeletal Susanoo arm to deflect a volley of incoming laser fire. "Orochimaru and Teach left behind a filthier legacy than we imagined."
Triple Threat: Pride in its Purest Form
The battle ignited instantly. Zoro lunged into the fray, his three swords clashing against the energy-blades of the automatons. "Armament Haki... coat my soul!" His blades turned a lustrous, pitch black, and he began to carve through the Saiyan-mesh armor as if it were parchment. "I don't just cut metal! I cut the will of the one who forged you!"
On the opposite flank, Vegeta was a whirlwind of destruction. "You think you can copy the strength of a Prince with mere gears and wires?" He gathered a mass of energy between his palms, his Ultra Ego flickering at the edges of his aura. "BIG BANG ATTACK!" The explosion leveled half of the guardians in a single, blinding flash of yellow light.
Sasuke moved like a ghost between the survivors. He utilized Amenotejikara to swap places with the automatons, causing them to fire their laser-beams into one another. With a surgical strike of his Chidori, he plunged his hand into the central control hub, short-circuiting the foundry's hive-mind.
Epilogue: The Shadow Emerges
As the three began to gather the heavy metal ingots, the entire mountain groaned. From the heart of the molten reactor, a figure emerged that should have been long dead.
It was Kabuto Yakushi, but he had transcended his snake-sage form. His body was a grotesque fusion of pale serpents, cybernetic Saiyan implants, and lidless Sharingan eyes embedded into the palms of his hands.
"What heavy-handed guests you are," Kabuto hissed, his voice a chilling blend of organic and digital tones. "The metal you seek... it is the very fuel required for the new 'Black Moon.' Thank you for saving me the trouble of extracting it."
Vegeta looked at him with pure, unadulterated disgust. "More filth from Orochimaru's lab. Zoro, Sasuke... take the metal and go. I'll deal with this scrap-metal snake myself."
But Kabuto only smiled, a thin, jagged line across his face, and pointed toward the opening of the volcano. "You're already too late... look at the sky."
Looking up through the caldera, the trio saw a gargantuan, dark object beginning to eclipse the golden fractures. It was a vessel of impossible size, humming with an energy that felt like a "Death Star"—a harbinger of the end.
