The first thing that returned was breath.

  It tore into him without warning, sharp and desperate, as though his lungs had been dragged up from deep water and forced to remember their purpose. Air scraped down his throat. His chest convulsed. Somewhere in the dark, a pair of eyes fluttered open, faint blue light trembling through unfocused pupils before fading back into shadow.

  Cold ground pressed against his back.

  Not stone alone. Something brittle. Dry. The thin crackle of dead grass shifting beneath his weight.

  Sight came slowly, like a curtain reluctant to rise. Darkness clung to everything, blurring shapes into uncertain ghosts. He pushed himself upright with shaking arms, each movement heavy, unfamiliar, as if his body no longer fully belonged to him.

  Only then did he notice the glow resting in his arms.

  A small, rounded mass of light.

  Soft. Warm. Quietly radiant in hues that blended blue and magenta into something almost alive. Its surface quivered with the gentlest motion, not quite solid, not quite liquid. It held together like clear jelly yet seemed woven from light itself. When his fingers tightened around it, it yielded slightly, smooth and dry despite its fluid form, as though warmth had been given shape.

  “What the…”

  The whisper left him hoarse, stolen by the cavern before it could become a real question.

  For a moment, he simply stared. Drawn in. Lost in the fragile glow.

  Then he forced himself to look away.

  “Where… am I?”

  His voice sounded small, swallowed by the darkness as he scanned his surroundings.

  A dark room?

  No.

  A cave.

  Shattered fragments like broken glass lay scattered across the ground, each piece leaking faint light that barely pushed back the dark. Moss crept along the earth. Thin patches of brittle grass spread in uneven clusters, color long since drained.

  He tilted his head upward, wincing at the stiffness in his neck.

  “Did I fall into an underground cave…? A sinkhole or something…?”

  His hands moved over his body, checking for wounds, for blood, for anything that would explain why he was still breathing.

  Nothing that made sense.

  “How am I even alive…? Didn’t that bomb destroy the whole—argh!”

  Pain answered.

  A sudden spike behind his eyes.

  Memories shattered across his mind in jagged flashes.

  Fire swallowing everything.

  Walls trembling, collapsing like fragile toys.

  His body moving on instinct, shielding Hana.

  That single, desperate hope that he could at least save her.

  A lie.

  It had never been meant for him.

  He was weak.

  Just someone who wrote stories for strangers to read when they were bored.

  He was meant to entertain. Not to protect.

  And yet…

  Hope lingered.

  Stubborn. Refusing to die.

  If he was alive, then maybe…

  Maybe she was too.

  All he had to do was find her.

  He tried to move.

  Nothing happened.

  His legs refused him, numb and distant, as if they belonged to someone else entirely.

  A pulse of instinct surged through him.

  His head lifted sharply. Blue light flickered through his eyes once more as his gaze snapped forward.

  Red.

  That was the first thing he saw.

  A cluster of blood-colored crystal, glowing faintly in the dark.

  Then the shape formed around it.

  A claw.

  Jagged. Heavy. Slowly advancing toward him.

  Time stretched thin.

  His body would not obey. Only his neck shifted, straining with painful effort. The crystal mass swept past his face by the smallest margin and slammed into the wall behind him.

  This novel's true home is a different platform. Support the author by finding it there.

  Stone cracked.

  A dent larger than his body caved inward.

  His throat tightened as he swallowed air that refused to reach his lungs.

  Then, suddenly, control returned.

  He moved without thinking, scrambling backward, forcing distance between himself and the thing that hunted him. When he finally looked up—

  It revealed itself.

  A sleek, rocky figure hovering above the ground, fragments barely connected yet held together by some unseen force. From where a face should have been, a black orb rotated slowly, leaking a pressure so heavy the air itself seemed to thicken.

  It turned.

  Locked onto him.

  Fear settled deep in his bones.

  He had survived an explosion…

  Only to be killed by a monster in a cave?

  “Could this day get any wors—”

  The world slowed.

  Blue light pulsed through his vision again.

  His body froze with it.

  To the side, death waited inches away.

  The massive crab-like claw poised to crush his arm.

  He tried to move.

  Too slow.

  The claw came down.

  Pain exploded through him as the world snapped back to full speed.

  His scream tore across the cavern, raw and endless. Blood burst outward as crushing force severed his arm completely.

  ---

  ---

  He collapsed to his knees, the taste of iron flooding his mouth.

  Warm liquid spilled down his side.

  The glowing sphere slipped from his grasp and rolled to the ground near his feet.

  “W-what’s… happening…? Why…? WHY?!”

  The stone guardian stepped closer, tossing aside what remained of his arm as it raised its crimson claw for the final strike.

  He understood only one thing.

  He was going to die.

  And the worst part—

  He almost didn’t care.

  He had already failed.

  Failed to protect his sister.

  Failed the girl who trusted him with her life.

  Death felt deserved.

  He would accept it.

  He would—

  No.

  That wasn’t right.

  It never was.

  “Haruto…”

  A whisper.

  Soft and Familiar.

  His eyes widened.

  Pain vanished.

  Light surged through his pupils as time slowed once more.

  This time, he moved.

  Not from strength.

  From something deeper.

  He forced himself upright as the claw descended toward his skull, barely slipping past the crushing blow. His gaze locked onto the black orb embedded in the creature’s head.

  His hand shot forward.

  Grabbed it.

  Resistance fought back, an unseen force anchoring the core in place. He pulled anyway, teeth clenched, vision trembling. The body lashed out on instinct, claws closing toward him again.

  He raised his arm, positioning the core between the converging blades—

  The claws crushed together.

  At the final instant, he tore his hand free.

  The core shattered.

  Light died.

  The guardian collapsed into lifeless stone, debris scattering across the cavern floor.

  Silence followed.

  Haruto dropped to his knees.

  Every borrowed movement demanded payment.

  Bones screamed. Flesh tore. His body felt like it was breaking apart from the inside.

  Pain returned all at once.

  Darkness crept in at the edges of his vision as he fell forward, the ground rising gently to meet him.

  His final breath slipped out in a fragile whisper.

  “Hana…”

  ...

  The cavern fell into stillness.

  Dust settled slowly through the dim air, drifting across shattered crystal and broken stone. Nothing moved. Nothing breathed.

  For a moment, even time seemed unsure whether it should continue.

  Then—

  The small sphere of blue-magenta light trembled.

  It remained motionless at first, as if listening to a world it did not yet understand. A faint pulse rippled across its soft, translucent surface. Slow. Uncertain.

  Carefully… awkwardly…

  It moved.

  Not a step.

  A gentle roll, like liquid learning the shape of gravity.

  The tiny slime shifted across the rough ground in uneven motions, pausing between each effort as though the act of moving itself demanded too much strength. Still, it continued forward, drawn by something quiet and instinctive.

  Toward him.

  Haruto lay where he had fallen, unmoving beneath the dim glow of dying crystal fragments. His breathing was shallow, fragile enough to disappear if the silence pressed any harder.

  The slime reached his side… hesitated…

  Then slowly climbed.

  Its body softened as it rose onto his chest, spreading just enough to rest there without weight, without pressure. Warm. Faintly luminous. Exhausted in a way only something newly born could be.

  And there, against the quiet rhythm of his heartbeat—

  It stilled.

  Not far away, something else waited.

  A severed arm lay abandoned among scattered debris, dark blood drying across the stone.

  Seconds passed.

  Then—

  A twitch.

  So small it could have been imagined.

  Another.

  At the same moment, the torn shoulder at Haruto’s side shuddered in answer, muscle tightening beneath ruined flesh as if called by a distant command.

  The air grew heavy.

  Without warning, the severed limb collapsed inward—

  bursting apart into a dense mass of blood and muscle that should not have been able to move… yet it did.

  The writhing crimson gathered itself, drawn across the ground by an unseen pull. Bone fragments twisted. Threads of flesh stretched like living roots searching for soil.

  In a single violent instant—

  It surged back.

  The mass slammed into the torn shoulder and fused seamlessly with his body. Bone snapped into place. Muscle rewove. Skin closed as though time itself had reversed its cruelty.

  Even torn fabric mended, threads pulling together until no wound remained.

  The slime flinched.

  A small ripple passed through its soft body as scattered blood across the cavern floor began to stir. Droplets trembled… lifted… gathered together in slow, unnatural motion.

  They merged into something larger.

  Darker.

  Alive.

  The growing mass swelled into a shifting crimson shape, its surface folding and unfolding like a silent tide. No eyes. No mouth. Yet its presence carried a quiet, suffocating hunger.

  The tiny slime trembled harder and pressed itself closer against Haruto’s chest, hiding behind him as if instinct alone understood danger.

  The blood-formed creature expanded once more—

  Then struck.

  It collapsed downward in a sudden, violent pounce upon the crumbled remains of the stone guardian. Rock and crystal vanished beneath the consuming red, devoured without sound, without resistance.

  Seconds passed.

  Nothing remained.

  The creature stilled…

  shrank…

  spiraled inward like a draining whirlpool—

  And slipped silently back into the healed flesh of Haruto’s arm, disappearing through unbroken skin as though it had never left.

  No blood remained on the ground.

  No wound.

  No trace.

  Only silence.

  Time drifted.

  The cavern, emptied of violence, felt strangely peaceful now—like a storm that had been forgotten.

  Slowly, the small slime stirred again.

  It lifted itself just enough to look around, its faint glow brushing across quiet stone and shattered crystal. No enemies. No movement. Only the steady rise and fall beneath it.

  Safe.

  At last, it settled back down against his chest, soft body relaxing as it melted gently into a resting shape—still, yet quietly alive.

  And in the darkness of the ruined cavern,

  the two of them slept.

  ...
