The Calamity Blade descended, a guillotine of white-hot magma and primordial shadow. Time itself seemed to curdle around the strike, the heavy air turning to glass under the sheer gravitational pressure of Zalthazar's might. Yuki, his energy reserves completely shattered, could do nothing but hold his breath and wait for the searing erasure of death. He closed his eyes, the image of Alya's tear-streaked face burned into his retinas.
But the end did not come.
Instead, the sky above them screamed. A high-frequency sonic boom shattered the heavy silence, instantly followed by a rain of metallic cylinders from the poisonous violet clouds. Thump. Thump. Thump. The moment the cylinders hit the molten asphalt, they detonated. There was no fire, only a massive, explosive release of hyper-dense, electromagnetic smoke. The thick, silvery fog erupted like a geyser, instantly blinding the infrared and thermal vision of the Void-Walkers and shrouding the entire battlefield in an impenetrable, static-filled veil.
From the depths of the smoke, a mechanical beast tore through the ruins. It was a massive, heavily armored recovery unit—Kinzuko's masterpiece. Before Yuki could even comprehend what was happening, the robot's articulated hydraulic arms scooped him and Alya up with terrifying precision. The machine didn't pause for a microsecond. Heavy-duty, all-terrain treads deployed from its legs, hitting the ground with a screech of burning rubber and sparking metal. Its thrusters flared, and the robot rocketed backward, tearing through the rubble of Agra at breakneck speed.
High above the retreating rescue unit, the drone that had dropped the smoke bombs began to shift. Gears ground together, metal plates reconfigured, and within seconds, the sleek flying machine transformed into a towering, humanoid combat mecha. It slammed into the ground between the fleeing recovery robot and the towering giant of magma.
Zalthazar simply stood there, his molten eyes narrowing as the smoke cleared. The combat mecha raised its plasma-cannons and unleashed a barrage of concentrated energy beams straight at the Primordial Devourer's chest.
Zalthazar didn't dodge. He didn't even raise his sword. The plasma beams struck his rocky exterior and fizzled out like water hitting a hot stove. With a slow, almost bored motion, Zalthazar raised his massive hand and snapped his fingers.
CRACK.
The combat mecha crumpled as if crushed by an invisible, planetary fist. Its metal screamed, wires sparked, and in the blink of an eye, Kinzuko's greatest defensive drone was reduced to a mangled, burning cube of scrap metal.
Zalthazar watched the recovery robot disappear over the horizon. He didn't pursue. Instead, a sinister, rumbling laugh vibrated from deep within his molten chest, shaking the loose debris around him.
"Run, little mice," Zalthazar sneered, his voice a tectonic grind that echoed through the dead city. "Let us see how far your frail legs can carry you. They slaughtered my treacherous children... but they will soon learn that I am not so easily broken. I am the father of the void. The strongest in the multiverse. The entire cosmos will be my throne, and I have all the time in the world to watch you despair." With a heavy turn, the giant melted back into the shadows of the ruined city, leaving nothing but burning earth behind.
Miles away, hidden deep beneath the treacherous mountains in a concealed, reinforced subterranean cavern, the atmosphere was suffocatingly bleak. The cavern was massive, lit only by flickering, low-power fluorescent tubes and the soft glow of Kinzuko's terminal screens. Huddled in the corners were the survivors—dozens of ordinary humans, their faces painted with dust, grime, and the unmistakable hollow stare of absolute terror.
The heavy steel blast doors hissed open, and the recovery robot skidded inside, its chassis smoking and wheels melted to the rims from the intense friction. The moment the mechanical arms lowered Yuki and Alya to the cold stone floor, a collective gasp rippled through the survivors.
They had seen Yuki fight before. They knew him as the untouchable Void-Monarch, the invincible boy who had carved a safe haven for them out of hell itself. But now, looking at him, their hope shattered. Yuki's armor was completely destroyed, his chest covered in horrific, jagged burns, and his breathing was shallow, a wet, rattling sound that echoed in the quiet cave. He was unconscious, clinging to life by a fragile thread.
"Move! Everyone, get back!" Kinzuko screamed, sprinting away from her command console with a medical kit slung over her shoulder.
From the shadows of the terrified crowd, an old man shuffled forward. He was a traditional healer, an ancient doctor whose knowledge predated the apocalyptic technology of the invaders. Without a word, he knelt beside Yuki, pulling out a satchel of dried herbs, pungent roots, and rudimentary bandages.
"His internal energy is entirely depleted," the old doctor muttered, his voice trembling as he began applying a thick, green paste to Yuki's burned chest. "He is human. Without his... special powers, his body is just flesh and bone. The trauma is too deep. He will not wake up for many days, perhaps longer. It is a miracle his heart still beats."
Kinzuko bit her lip so hard it bled, turning her attention to Alya. Alya's condition was equally gruesome, but as Kinzuko began to clean the wounds, she noticed something incredible. The deep lacerations on Alya's silver-blue skin were already knitting themselves back together.
"She has a body from Universe 12," Kinzuko whispered to herself, scanning Alya's vitals with a handheld device. "Her cellular regeneration is off the charts. Give her twelve hours, maybe less, and she'll be physically fully recovered."
But the realization brought no comfort to the genius hacker. If Alya can heal this fast, yet she was brought to the brink of death so easily... just what kind of monster are we facing? Kinzuko thought, a cold sweat breaking out on her forehead. Are we really going to be able to beat this guy?
The whispers among the survivors grew louder.
"If he can't beat that monster... we're dead."
"We should run. We have to hide deeper."
"It's over. The world is ending."
The panic was infectious, spreading like a virus through the cavern. Kinzuko's hands balled into tight fists. She stood up, her small frame vibrating with sudden, explosive rage. She turned to face the crowd, her eyes blazing with an intensity that silenced the room instantly.
"Shut up! All of you, just shut up!" Kinzuko's voice cracked like a whip, echoing off the cavern walls. "Are you really going to sit there and cry? If you want to die, fine! But if you keep living in fear like cowards, that monster will come here, and he won't hesitate to slaughter every single one of us! Have you forgotten who saved you? Have you forgotten who bled to bring you to this cave?"
She pointed a shaking finger at Yuki's unconscious body. "If we had thought 'we can't do this' back then, none of you would be breathing right now! So control your fear! If you can't fight, then don't make our burden heavier by whining! We will save you. We will find a way. You just need to have faith!"
Her words hung in the air, heavy and absolute. The survivors lowered their heads in shame, the panic subsiding into a grim, determined silence. Kinzuko took a deep breath, wiping the sweat from her brow, and marched straight back to her laptop. She didn't sleep. She didn't eat. For the entire night, the only sound in the cave was the furious, rhythmic clacking of her keyboard as she analyzed streams of encrypted data.
The next morning, the dim lights of the cavern simulated a bleak dawn. Alya's eyes fluttered open. She gasped, sitting up quickly. The wounds on her body were completely gone, leaving only smooth, flawless skin.
Before she could fully process her surroundings, a small body crashed into her. Kinzuko wrapped her arms around Alya's neck, burying her face in the princess's shoulder as violent sobs wracked her frame.
"You're awake... I thought... I thought I lost you guys," Kinzuko cried, her tough exterior finally crumbling.
Alya gently patted the hacker's back, a soft, sorrowful smile on her face. "I'm okay, Kinzuko. I'm right here. Don't worry anymore... I will fix everything. I promise."
Kinzuko pulled back, hastily wiping her tears with the back of her sleeve. She took a deep, shaky breath. "Alya... before my combat mecha was destroyed yesterday, I managed to do something. I embedded a micro-audio transmitter in its chassis. When the villain crushed it, the transmitter attached to his body. I spent the whole night listening to his monologues and cross-referencing the energy signatures."
Alya's expression turned serious. "And? What did you find out?"
"He's not a random monster, Alya. And he's definitely not a minion," Kinzuko said, her voice dropping to a terrified whisper. "He... he is the Father. The progenitor of the villains we fought in Universe 12."
Alya's eyes widened in sheer horror. "The Father? But... that's impossible. The legends say the First Calamity was sealed away eons ago because his power was too absolute, too dangerous even for his own kind."
"The legends were real," Kinzuko confirmed grimly. "His own children—the villains you and Yuki defeated—betrayed him. They couldn't kill him, so they sealed him away here, on Earth, on Planet 3 of Universe 3. They wanted to rule without living in his shadow. But when you and Yuki killed them... the biological seal tying him to his slumber was broken. We didn't just win a war, Alya. We accidentally woke up the strongest entity in the multiverse."
Alya looked over at Yuki. He was still lying motionless on a makeshift cot, his chest wrapped tightly in the doctor's bandages. The boy who had sacrificed his humanity, his sanity, and his blood for her was now broken, perhaps permanently. A heavy, suffocating guilt clamped down on her heart.
"I always thought the stories about the Multiverse Conqueror were myths," Alya murmured, her fists clenching so hard her knuckles turned white. "Now I know. It wasn't a story. It was history."
"He's too strong, Alya," Kinzuko said, her voice trembling. "Can we really beat him? Even Yuki's Void-powers were useless."
Alya's silver eyes hardened, a cold, absolute resolve replacing her fear. "We will defeat him. Or rather... I will."
Kinzuko blinked, confused. "What do you mean?"
Alya stood up, her posture rigid, her gaze fixed on the cavern wall. "There is one final path. A forbidden technique of the Royal Bloodline of Universe 12. My digital soul, combined with this biological body, acts as an infinite vessel. I have the power to absorb anyone, to lock their consciousness and power entirely within my own core."
Kinzuko's eyes widened. "You... you can absorb him? Why didn't we use this before?!"
"Because there is a price," Alya said, turning to look at her friend with a heartbreakingly calm expression. "The Law of Equivalent Exchange. To lock away an entity, my soul must use its own life-force to build the cage. If the target is weak, it takes a few days, maybe a year off my life. But Zalthazar... his power is primordial. If I absorb him..."
"Alya, no," Kinzuko stepped back, shaking her head violently. "No, you don't mean..."
"My life-force will be drained entirely. My core will shatter from the inside out. I will die, Kinzuko."
"NO!" Kinzuko yelled, grabbing Alya's shoulders. "Absolutely not! I won't allow it! We survived before, we can think of another way! We'll build a bomb, we'll hack the planet's core, anything! You are not throwing your life away!"
"The situation is completely different now!" Alya yelled back, tears finally spilling from her eyes. "He nearly killed Yuki and me with a fraction of his power! There is no bomb, there is no hack that can kill a god! Look at Yuki! Look at him! He gave up everything for me. Now, it's my turn to protect him. I am going tonight."
"I said no!" Kinzuko snarled, stepping between Alya and the cavern exit. "I'm not letting you walk out of here. If I have to tie you down, I will."
Alya looked at the fiercely loyal hacker, a sad, affectionate smile touching her lips. "I'm sorry, Kinzuko. Humans are brilliant, beautiful creatures. But you all share one very simple, fatal flaw."
Before Kinzuko could react, Alya's hand darted out. She pressed a cloth, soaked in the old doctor's potent herbal anesthetic, directly over Kinzuko's nose and mouth. Kinzuko's eyes went wide with shock. She struggled, her hands clawing desperately at Alya's wrist, but the Royal biology was too strong. Within seconds, the hacker's eyes rolled back, and she went limp in Alya's arms.
Alya gently laid her friend on the ground, brushing a strand of hair from Kinzuko's face. "Forgive me. Tell Yuki... tell him I loved him."
Without another backward glance, Alya walked out into the toxic night.
Hours later, Kinzuko woke up with a sharp gasp. Her head was pounding, the acrid smell of the herbs still lingering in her nose. She scrambled to her feet, her heart hammering against her ribs like a trapped bird.
"ALYA!" she screamed, tearing through the cavern to her terminal.
Her fingers flew across the keyboard, bypassing security protocols and instantly connecting to her satellite surveillance grid. She deployed every single drone, every combat robot, every scrap of technology she had left, sending them swarming toward the coordinates of Zalthazar's terrifying energy signature.
The main monitor flickered to life, displaying a chaotic, grainy feed from the lead drone.
It was too late.
The camera zoomed in on the ruined plaza of the city. Zalthazar stood towering in the center, his magma glowing fiercely in the dark. But standing right in front of him, looking no bigger than an insect against a mountain, was Alya.
"Foolish girl," Zalthazar's voice boomed over the audio feed. "Have you come to offer yourself as a tribute?"
Alya didn't speak. She raised her hands, her silver-blue hair whipping around her face as a blinding, ethereal light erupted from her chest. The Royal Core—the amalgamation of her digital soul and biological heart—began to spin violently. A massive, gravitational vortex of pure white energy tore open the space between them.
Zalthazar's smug expression vanished, replaced by sheer, unadulterated panic. "What is this?! What are you doing?!"
"I am locking you away," Alya's voice echoed, carrying the weight of a dying goddess. "Forever."
The vortex latched onto Zalthazar. The giant roared, digging his massive feet into the earth, trying to resist the pull. The two Void-Walkers beside him shrieked, instantly disintegrating into ash as the sheer pressure of Alya's technique ripped their existence apart.
Kinzuko watched through the screen, tears streaming down her face, as her swarm of robots finally arrived at the perimeter, completely unable to breach the hurricane of energy.
With a final, earth-shattering scream that shattered the camera lenses of half the drones, Zalthazar's massive body distorted, stretched, and was sucked entirely into the glowing core in Alya's chest.
The blinding light vanished as quickly as it had appeared. The oppressive, heavy atmosphere of the planet lifted instantly. The violet clouds began to part, revealing the pale light of the moon.
On the screen, Alya stood alone in the center of the crater for a single second. Then, like a puppet whose strings had been cut, her eyes rolled back, and she collapsed violently onto the cold, hard ground, unmoving.
"Alya..." Kinzuko choked out in the cavern, falling to her knees in front of the monitors.
At that exact, precise microsecond, a sharp gasp echoed from the back of the cave.
Yuki's eyes snapped open. The bandages around his chest tightened as he bolted upright, cold sweat pouring down his face. His gray eyes, wide with panic and a terrifying premonition, frantically scanned the dim room, ignoring the agonizing pain tearing through his body.
"What happened?" Yuki's voice was hoarse, desperate, and filled with a chilling dread. "Where is Alya?"
