Ren had seen death before. During his residency, he'd stood in quiet hospital rooms where monitors flatlined and families wept behind closed doors. He knew the stillness that came after, the way a body became just a body, emptied of whatever made it a person.

  But this wasn't that.

  This wasn't a sterile room with white sheets and the hum of machines. This was violence painted across concrete and rust. This was wrong in a way that made his stomach turn and his hands shake.

  He stared at the corpse sprawled in the alley.

  The body was twisted at angles that didn't make sense. One arm bent backward at the elbow, fingers splayed against the ground. The chest had been opened, ribs spread wide like gates. But there was no blood pooling beneath it. Instead, something darker seeped into the cracks of the pavement, thick and viscous, catching the dim light like oil.

  Ren's throat tightened. He pressed a hand against the wall to steady himself, feeling the grit of old brick under his palm.

  "What the hell is this?" he whispered.

  The panel in his vision pulsed again, the text flickering slightly.

  [System Binding Progress: 85%]

  A sound cut through the silence.

  It started low, almost like a groan, then climbed higher until it became a howl. Deep and guttural, it rattled the air itself. It wasn't the sound of an animal. Animals had purpose in their cries, territory or hunger or pain. This was different. This sounded like something that had learned what a predator should sound like and was doing its best impression.

  Ren turned toward the noise, his pulse hammering in his ears.

  The building across the alley exploded outward. Concrete chunks flew in all directions, crashing onto the ground with heavy thuds. Glass rained down in slow, glittering arcs. Through the wreckage came a creature that made Ren's legs lock in place.

  It was shaped like a wolf, but only in the loosest sense. It stood nearly three meters tall, its body covered in patches of exposed bone and rusted iron that looked welded onto flesh. Its face was torn open at the cheeks, revealing two full rows of teeth that didn't match, some sharp, some blunt, all stained dark. Its claws dug into the pavement with each step, leaving deep grooves behind.

  The creature didn't pause to sniff the air or scan its surroundings.

  It saw him immediately.

  Then it charged.

  Ren's body moved before his mind caught up. He spun and ran, his shoes skidding on the slick pavement. His shoulder clipped a trash bin, sending it crashing over with a metallic clang. The noise didn't matter. The creature wasn't slowing down.

  He heard the scrape of claws against brick behind him, a sound like nails dragged across stone. The footsteps were fast, each one impossibly close to the last.

  His lungs burned. His legs felt heavy, uncoordinated. He wasn't an athlete. He'd spent the last five years hunched over textbooks and surgical tables, not running for his life.

  The thought hit him like a punch to the chest.

  I'm going to die.

  Not in some distant, abstract way. Not someday when he was old and tired. Right now. In this alley. Before he even understood what was happening.

  The panic swallowed him whole. It wasn't the fear of pain, though that was there too. It was the fear of being erased, of dying without knowing why, without even getting the chance to figure out what the hell was going on.

  This tale has been unlawfully obtained from Royal Road. If you discover it on Amazon, kindly report it.

  His thoughts spiraled, frantic and disjointed.

  Then a voice cut through the chaos.

  It wasn't the system's mechanical tone.

  This voice was different. Clear. Resonant. Female.

  It sounded like it came from everywhere at once, like it was speaking directly into the space between his ribs.

  "O Great Hero, awaken."

  The world vanished.

  .

  .

  .

  Ren wasn't sure when he lost consciousness. One moment he was running, the next his lungs filled with air that felt too thick, too warm. The taste of copper clung to the back of his tongue, sharp and metallic.

  He opened his eyes.

  The alley was gone.

  He lay on something soft but uneven, like stitched leather that had been patched together too many times. The surface beneath him rose and fell in a slow, rhythmic pulse, as if he were lying on the chest of something massive and breathing.

  He pushed himself up on shaking arms, his palms pressing into the strange material. It was warm. Warmer than it should have been.

  The sky overhead stopped him cold.

  It was the color of raw muscle, deep red streaked with darker veins that branched out like a circulatory system. Where clouds should have been, there were floating masses that looked disturbingly organic. They pulsed in midair, tethered to nothing, their surfaces slick and glistening.

  In the distance, buildings rose against the horizon. They were Victorian in style, tall and elegant with ornate detailing, but their proportions were all wrong. Some leaned forward at impossible angles, their bases too narrow to support their weight. Others spiraled upward like corkscrews, twisting into the red sky. One building was slowly collapsing in on itself, folding and folding but never quite reaching the ground.

  Ren stood, his legs unsteady beneath him.

  The floor he'd been lying on wasn't a floor at all. It was an operating table. Massive. Easily the size of a basketball court. Rusted restraints lay open along its edges, and surgical hooks hung suspended in the air above it, rotating slowly like wind chimes made of metal and threat.

  His breath came in short, shallow bursts.

  "This isn't a dream," he said aloud, just to hear his own voice. It sounded small, swallowed by the open space around him.

  The voice returned.

  "O Great Hero, please save those who suffer in the hands of nightmare abominations."

  Ren spun in place, trying to locate the source. The voice didn't come from any one direction. It vibrated beneath his skin, resonating in his skull.

  "If thou pass the trial, thou shall become Awakened and return to thy own world."

  "Wait," Ren said, his voice cracking slightly. "What trial? Who are you?"

  No answer came.

  The air shimmered.

  A tear formed in the sky above him, long and jagged, like a wound splitting open. It stretched wider, revealing darkness beyond. From it descended shapes that made Ren's stomach lurch.

  Mouths.

  Dozens of them. Maybe hundreds. They fell toward him like rain, each one twisting and writhing in midair. They were shaped like screams given form, flesh and teeth and nothing else.

  Ren's legs locked. He couldn't move. Couldn't breathe.

  A panel appeared in his vision, but this time it stuttered. The text flickered, the words shifting and glitching before stabilizing.

  [Initializing... ERROR.]

  [Genre Mismatch Detected: World is not recognized as a standard Hunter realm.]

  [Analyzing the surrounding environment...]

  [Dimensional layer breach confirmed.]

  [The host has been transferred to an Eldritch Horror world by an unknown external force.]

  [Adjusting system parameters.]

  [Synchronizing with a corrupted narrative field...]

  [Fixing genre alignment... COMPLETE.]

  The text cleared, replaced by a new message.

  [You have been chosen as the Host of the Doctor of the Ruin Gospel System.]

  [Initializing.]

  Ren stared at the screen, his mouth slightly open.

  Above him, the sky pulsed like living tissue. The veins throbbed in slow, deliberate rhythm. The crimson clouds crawled across the expanse, dragging shadows with them. The ground beneath his feet felt slick, like old leather soaked in something he didn't want to name.

  He let out a long, shaky breath.

  The mouths were still falling. He could see them now, closer than before, their twisted forms descending in a slow spiral.

  He swallowed hard, his throat dry.

  "This..." He paused, the absurdity of it hitting him all at once. "I just got isekai'd twice?"

  The words hung in the air, ridiculous and true at the same time.

  His hands curled into fists at his sides. His heart was still racing, but beneath the panic, something else stirred. A faint, bitter thread of disbelief mixed with something that might have been anger.

  He'd spent his entire life working toward something normal. Medical school. Residency. A future that made sense. And now he was standing on a giant operating table in a world that looked like it had been pulled from the nightmares of a dying god, watching mouths fall from the sky while a corrupted system told him he was some kind of hero.

  He laughed once, short and sharp, more reflex than humor.

  "Great," he muttered, rubbing his face with both hands. "Just great."
