Yuuta slept peacefully, curled against Sophia's side, his small body finally relaxed after weeks of healing.
The wounds that had covered him were gone—not completely, not entirely, but enough. The healing potions that had been forced into him during the experiments had done their work, slowly, painfully, but surely. His skin, once a map of cruelty, was now smooth in places, scarred in others. His bones, once cracked and broken, had knitted together. His organs, once crushed and ruptured, had mended.
He was not whole. He would never be whole. But he was alive.
Sophia ran her fingers through his black hair, watching him sleep. His face, even in rest, held a softness that made her heart ache. His lips were slightly parted, his breath slow and steady, his small hand curled against his chest. He looked like any other child—ordinary, innocent, untouched by the horrors of the world.
But she knew better. She had seen his scars. She had counted his wounds. She had held him while he cried and listened to him whisper about doctors and needles and tanks.
She had decided, in that first moment, to save him. She had decided to protect him, to care for him, to give him the life that had been stolen from him. She had not known, then, that he would become her hope. Her reason for waking up each day. Her reason for continuing to survive in this dark, hopeless place.
She could not imagine a day without him now. She could not imagine going back to the silence, the loneliness, the endless, crushing emptiness of being alone. If anything happened to him, she would not be able to withstand it. She would break. She would shatter. She would become the thing she had been before—a creature of survival, not a person.
And then the siren began to wail.
Above them, in the laboratory, chaos had erupted.
The chief scientist stood in the center of the control room, his face pale, his hands trembling. Around him, his subordinates bowed low, their heads pressed against the cold metal floor, their bodies shaking with fear.
"What do you mean, it is gone?" the chief scientist demanded, his voice sharp enough to cut glass.
The senior scientist, a gaunt creature with too many eyes and too few teeth, stammered his response. "We... we checked the disposal records. The body was not in the Time Capscule. It was not in any of the disposal sites. We do not know where it went."
The chief scientist smashed his wine glass against the wall. The red liquid dripped down the metal like blood.
"Do you know what this means?" he shouted. "We accidentally used a real body. A real, living body of Death. And now we have lost it. For many years. many years, and no one noticed."
The scientists bowed lower, their foreheads touching the floor.
"It was Lala," one of them whispered. "She was in charge of Body. She did not tell us. She said she disposed of the body, but she did not."
The chief scientist's face twisted with rage. "I cannot let my project be ruined by this. Search every lab. Every disposal site. Every corner of this facility. Find me that child Corpse. If he is alive, he cannot be allowed to escape."
He paused, his eyes narrowing.
"Send out the siren."
The siren echoed through the laboratory, through the tunnels, through the well itself. It was a sound unlike any other—a low, pulsing frequency that vibrated through the stone and bone and metal, that seeped into the darkness and the shadows and the hidden places where things tried to hide.
It was designed to find something. To locate something. To wake something.
And when the frequency hit Yuuta, his eyes shot open.
He screamed.
His body jerked, arching off the furs, his small hands clawing at his chest. His mouth opened wide, and a sound emerged that was not human—not entirely. It was a scream of pain, of fear, of something waking up inside him that had been sleeping for a very long time.
A black shadow exploded from his body.
It was thick like smoke, viscous like oil, writhing like something alive. It filled the bone hut, pressing against the walls, pushing against the ceiling. It hissed—a sound that was not quite sound, not quite language, not quite anything that should exist in this world.
It was wrong. Heavy. Ancient.
Sophia clapped her hands over her ears, trying to block out the scream, trying to block out the pressure that was crushing her from all sides. She tried to reach for Yuuta, tried to cover his mouth, tried to stop the noise before it alerted the scientists above.
But she could not reach him. The pressure was too great. The shadow was too thick. She was pushed back, her body slamming against the bone wall, her head cracking against the stone.
She fell to the ground, gasping for air, and looked up at Yuuta.
"What... what is that?" she whispered.
The pressure was immense. It was like standing before a divine being—something ancient, something powerful, something that had no business existing in a child's body. She felt small, insignificant, helpless.
She was not afraid of him. She was afraid for him.
She finally understood.
This was why they had called him the Dragon Killer. This was why they had poured so much into him, sacrificed so many, committed so many atrocities. This was why they had named him Zero Karma.
He writhed on the stone floor, clutching his head, screaming like something inside was tearing him apart from the inside out. His body convulsed, arching off the cold ground, his back bending at an angle that should have been impossible for a child his age.
His fingers dug into his scalp, nails drawing blood, as if he could claw the thing out of his skull. His mouth was open wide, too wide, and the sound that came out was not human. It was deeper, older, more terrible—a roar that shook the walls of the well and sent cracks spiderwebbing across the stone, a sound that vibrated in the chest and made the very air tremble.
Above, in the laboratory, the guards heard it.
"Someone is alive in the well!" one of them shouted, his voice sharp with alarm, cutting through the hum of the machines. "Someone is alive down there!"
"Move, move! Take the tranquilizer guns! We need to secure the subject before it—"
"MAKE IT STOP!" Yuuta screamed, his voice raw, torn, barely recognizable as human. "MY HEAD! SOMETHING IS INSIDE ME!......AHHHHHHHHH!"
His voice rose, became something else—something that was not a scream, not a roar, but a vibration that resonated through the stone, through the darkness, through the very bones of the earth. The well trembled.
The walls shook. Cracks spread across the floor, and dust rained from above, filtering down through the darkness like gray snow.
Erza watched in horror. Her hands were pressed against her mouth, her eyes wide, her heart pounding. She had not known. She had never known that Yuuta had power, that something was sleeping inside him, waiting to wake.
He had never shown any sign of it in the weeks they had spent together. He had never glowed, never screamed, never released anything except his warmth, his kindness, his stubborn refusal to give up.
But now she saw it—the shadow aura that had exploded from him, thick and black and wrong. It was not magic. It was not mana. It was something else. Something ancient.
Something that should not exist in a human body. It writhed around him like living smoke, hissing and snapping, pressing against the walls of the well as if searching for an escape.
And he was in pain. Terrible, unbearable, soul-shattering pain. His small body was wracked with convulsions, his teeth clenched so hard that she could hear them grinding, his eyes rolled back in his head until only the whites showed.
Then he went silent. His body collapsed, limp and still, and he lay motionless on the cold stone floor. The shadow aura faded, sinking back into his skin, back into his blood, back into whatever dark place it had come from.
Above, the guards shouted with triumph. "We found him! We found him! There is a survivor hiding inside the death well!"
Sophia rushed forward. She fell to her knees beside him, her hands trembling as she wrapped her arms around his small, limp body. She pulled him against her chest, holding him tight, pressing her cheek against his hair. His skin was cold, too cold, and she could feel his heart racing beneath his ribs.
"Yuuta! Yuuta, I am here!" Her voice was shaking, but she did not let go. She could not let go. "Your big sister is here, okay? I am with you. Breathe. Just breathe."
His body was limp, heavy, but she held him. She rocked him back and forth, the way she imagined her mother had rocked her, before the war, before the well, before everything.
"Do not be scared. I have got you. I will not let anything happen to you."
Her warmth reached him. Slowly, like a dying stone cooling in the darkness, his trembling began to ease. The tension in his muscles relaxed. His breathing steadied.
His body relaxed in her arms, like a child waking from a nightmare.
He opened his eyes. They were red, swollen, terrified. The pupils were dilated, still adjusting to the darkness after whatever vision had consumed him.
"S... So... Sophia..." His voice was weak, barely a whisper, cracked and fragile. "It hurts... my head... I saw... a woman... it was dark... she was crying..."
Sophia held him closer, her hand gently stroking his hair, her fingers running through the black strands that had grown soft and clean.
"It is over," she whispered. "I promise. You are okay now."
But above, the guards were opening the death well. She could hear them—the creak of the metal grate, the clank of chains, the shouted orders. They were preparing to descend, to search every corner, to find the survivor who had been hiding in the darkness for so long.
Sophia's mind raced. She did not know how to save him. She did not know how to save herself. The guards would find them. They would take Yuuta back to the lab, back to the doctors, back to the torture. And she would be thrown back into the well, or killed, or worse.
She held Yuuta tighter, her eyes scanning the darkness for an escape that did not exist.
Then she heard it.
A growl. Not the growl of the hydra dogs, not the growl of any creature she had encountered in the well. It was deeper, older, more terrible. It echoed through the mountain, shaking the stone, rattling the bones that littered the floor.
Erza's eyes widened. She knew that sound. She had heard it before, on battlefields, in the dark places between worlds. It was the sound of nightmare creatures waking from their slumber.
Isvarn looked up, his ancient eyes sharp. "They are coming," he said.
Erza felt a chill in her spine. Her arms itched to kill, because what was coming was not a normal creature. It was nightmare creatures. And the sound echoing through the whole mountain was proof—almost a hundred of them.
That number could end an entire nation.
They came crawling from the shadows, devouring every living thing in their path. The guards at the well did not have time to scream. They were crushed by death crawlers—nightmare creatures that loved to crush their victims, to cripple them, to roll their massive bodies over them again and again, breaking their bones one by one, savoring the sound of cracking ribs and snapping spines.
The facility erupted into chaos. Screams of pain, roars of monsters, the clash of weapons against claws and teeth. The nightmare creatures had come, and they were hungry.
Sophia's expression twisted with horror. She did not know what was happening above, but she knew it was her only chance.
She lifted Yuuta into her arms, ignoring the pain in her muscles, the weakness in her limbs. He was light—too light, lighter than he should have been—and she held him against her chest as she ran to the back of her bone hut.
She had been digging for years.
Day after day, hour after hour, chipping away at the stone with a sharpened bone, widening the crack that had been there since before she arrived.
She had believed, against all reason, that she could escape. That she could dig her way out of the well and find freedom. That there was something worth surviving for.
And now, she was going to use it.
She pushed aside the giant leaves that covered the hole, revealing the dark tunnel beyond. It was narrow, barely wide enough for her to squeeze through, but it sloped upward, toward the surface. She could feel the cold air seeping down from above, carrying the scent of pine and earth and something else—something that might have been freedom.
Sophia looked down at Yuuta, still cradled in her arms, still weak, still terrified. His small body trembled against hers, and his red eyes—those crimson, blood-colored eyes that had seen too much pain—were fixed on her face, searching for reassurance, searching for hope, searching for someone to tell him that everything would be okay.
"Are they here to punish me?" he asked, his voice small and fragile, like a bird with a broken wing. "Did they come to take Yuuta back? Will they hurt me again?"
He was afraid. Not of the monsters above, not of the chaos, not of the screams echoing through the mountain. He was afraid of the doctors. Of the white coats. Of the needles and the knives and the cold, sterile smell of the lab.
Sophia's expression twisted with rage. Her green eyes, which had been hollow for so long, burned with a fire that had not been there before. Her hands, which had been gentle, tightened around him.
"No one is taking you from me," she whispered. Her voice was low, fierce, absolute. "I will not let them hurt you again. I swear."
She pulled away from him gently, just enough to look into his eyes. She placed a kiss on his forehead—soft, tender, the kind of kiss a mother might give a child before a storm.
"Yuuta, listen to me. I am going to save you. But you need to be brave."
"Brave?" he whispered.
"Yes. We are leaving this place. We are going outside. To the world."
"World?" His voice was uncertain, afraid. He had heard her speak of the world—the trees, the mountains, the rivers, the sun. But he had never seen any of it. He did not know if it was real.
She cupped his face in her hands, forcing him to look at her.
"My Yuuta, whatever you see up there—do not be afraid. Monsters, scientists, anyone who comes—do not be afraid. Be brave, okay?"
He nodded slowly, his red eyes still wide, still scared, but filled with something that might have been trust.
She stepped into the tunnel, and the darkness swallowed them both.
To the journey of freedom.
To be continued...
