Chapter Text
Seong Gi-hun had long since lost count of the demons he had killed.
The years had stripped such things of their individuality. Once, he had remembered every face, every battle, every nightmare that crossed his path. Now they blurred together into an endless procession of claws and fangs, black blood and ruined sanctuaries, creatures that emerged from the darkness only to perish beneath his blade. Entire lifetimes had passed for the mortals around him. Kingdoms had risen and vanished. Cities had been built atop the bones of older cities. Generations had lived and died while Gi-hun remained, forever walking the fragile boundary between worlds.
And still the demons came.
Gi-hun swung his sword in a wide arc, and the creature collapsed at his feet with a final, agonised shriek.
Its enormous body convulsed violently upon the chapel floor as black blood spilled across ancient stone. Shadows poured from the mortal wound in its chest like smoke escaping a dying fire, curling upward through shafts of rainwater before dissolving into nothingness. The smell it left behind was foul enough to sting the back of his throat.
For several moments, silence settled over the ruined sanctuary.
Rain continued to fall through the fractured roof high overhead, drumming softly against broken pews and gathering in shallow pools amongst scattered fragments of stained glass. The weather-worn saints watching from the chapel windows had long since lost their faces to time, their features eroded into blank expressions that seemed oddly fitting for a place abandoned by both God and man.
Gi-hun lowered his sword.
A familiar weariness settled over him. Not physical exhaustion; his body had ceased to recognise such limitations long ago. No, this was something deeper. A fatigue that seemed lodged within his very soul. The kind that came from spending decades pursuing a myth.
He could no longer remember exactly how many years had passed since he first began searching for the other half-breed mentioned in his mother's journal. The decades had bled together until they became impossible to separate. Clues had appeared only to vanish. Ancient records had yielded fragments of forgotten histories. Demons had spoken half-remembered names. Spirits had offered riddles instead of answers.
And yet every trail ultimately led back to the same destination. The same name.
In-ho.
The name lingered within his thoughts with an almost painful familiarity.
Sometimes Gi-hun wondered whether he had spent centuries chasing nothing more than loneliness given shape. Whether the man truly existed, or whether his desperate desire for connection had transformed a handful of scattered clues into an obsession.
Yet the certainty had returned the moment he entered this chapel.
Somewhere within these walls lay something he had spent a lifetime searching for.
A sharp crackle interrupted his thoughts.
The walkie-talkie clipped to his belt sputtered to life amidst a burst of static.
"Gi-hun?"
Jung-bae's voice emerged through the interference.
"Please tell me you're still alive."
Despite himself, Gi-hun felt the faintest hint of amusement tug at the corner of his mouth.
"I'm alive."
A sigh of relief crackled through the speaker.
"Good. Because if you got yourself killed after dragging me halfway across the world, I'm going to be very annoyed. Don’t forget, you’re my ride home."
The response came so quickly and so naturally that it almost felt comforting.
Almost normal.
Gi-hun glanced toward the shattered entrance of the chapel.
"You can come in."
There was a brief pause.
"You’re sure?"
"The demon's dead."
Another pause.
"Mostly dead, or…?"
Gi-hun glanced down towards the crumbling, still form of the beast he had just slain. "Definitely dead, Jung-bae."
"Right. Coming in."
A few moments later, footsteps echoed across wet stone as Jung-bae entered through the ruined doors, carrying a lantern and looking distinctly unimpressed by the weather. Rainwater dripped from his coat as he surveyed the devastation.
His gaze moved from the demon's rapidly disintegrating corpse to the shattered furniture and finally to Gi-hun himself.
"Well," he said. "I've definitely seen worse."
Gi-hun's eyes drifted briefly toward the remains of the creature.
Even now, black ash continued to peel away from its body and scatter across the chapel floor. In death, it seemed smaller than it had moments before, diminished somehow. The terrible presence that had filled the sanctuary during the fight had already begun to fade.
For a moment, he found himself replaying the battle.
The demon had been dangerous, certainly. Fast enough to cross the chapel in the space of a heartbeat and strong enough to tear through stone with its claws. A single mistake would have been enough to kill an ordinary human.
Yet there had been something unfinished about it.
Something almost adolescent.
Its attacks had been driven by instinct rather than discipline, relying on brute aggression instead of strategy. It had lunged when patience would have served it better, exposed weaknesses that a more experienced creature would never have revealed, and allowed its temper to dictate its movements. Even the antlers crowning its head had seemed relatively small compared to some of the ancient horrors Gi-hun had encountered over the centuries.
A century old at most, he guessed. Perhaps less. Young by demonic standards.
The thought brought him little satisfaction.
He remembered being twenty-four years old and discovering that demons were real. He remembered the confusion, the fear, and the impossible weight of responsibility that had descended upon him after his mother's death. A hundred years could seem like an eternity to mortals.
To Gi-hun, it barely felt like the beginning of a life.
His gaze lingered on the crumbling corpse for another moment before he looked away.
"I've definitely fought worse," he said quietly.
The understatement was almost laughable.
He had crossed blades with creatures old enough to remember the birth of kingdoms. He had survived encounters with demons whose names had been spoken in frightened whispers for millennia. Compared to some of the things lurking within the deepest reaches of the Netherworld, this creature had been little more than a child playing at monstrosity.
Jung-bae studied him for a moment before snorting softly.
"That's never as reassuring as you think it is."
A faint smile touched Gi-hun's lips.
"No," he admitted. "It probably isn't."
Before Jung-bae could reply, a quiet sob drew both their attention toward the altar.
The family remained huddled where the creature had cornered them.
A woman clutched a young child tightly against her chest. Beside them, a man still gripped a rusted iron poker despite the fact that his trembling hands could barely hold it.
All three stared at Gi-hun.
And all three wore the same expression. Relief. Gratitude. Fear. No matter how many lives he saved, or how many monsters he killed, the combination never changed.
Gi-hun felt the familiar ache settle heavily within his chest as he turned towards Jung-bae. Mortal lives were so fragile. He knew that he would lose Jung-bae one day, but he wasn’t going to let carelessness bring that day sooner.
"Stay back," he said quietly.
Jung-bae immediately understood, his expression sobering.
Gi-hun approached the family slowly. If they were human, he had to be careful not to startle them further, but at the same time caution remained second nature after so many years. Demons had become skilled at disguising themselves. More than once apparent victims had revealed monstrous faces beneath human skin.
The child buried her face against her mother's shoulder as he approached.
Gi-hun studied each of them carefully. He took in the rapid heartbeats, the scent of rain and fear, and the warmth of living flesh.
They were human.
Only then did he allow himself to relax.
"You should leave," he said gently.
The mother opened her mouth as though preparing to thank him, but Gi-hun shook his head.
"You don’t need to."
The father swallowed nervously before helping his family to their feet.
As they hurried toward the doors, Jung-bae stepped politely aside to let them pass. He offered them an awkward but well-meaning smile that looked strangely out of place amidst the ruins.
"Safe trip home," he said.
The family stared at him for a moment, clearly uncertain how to respond to a man standing casually beside the corpse of a nightmare. Then, without a backwards glance, they disappeared into the storm, the sound of their footsteps gradually fading into the darkness beyond.
Only when they were gone did silence return to the chapel, broken only by the slight shuffling of footsteps as Jung-bae turned toward him.
"So," he said quietly, glancing toward the ancient altar at the far end of the sanctuary. "This is the place?"
Gi-hun followed his gaze. Beneath the altar, hidden beneath centuries of stone and dust, lay an ancient crypt. And—if their research proved true—within that crypt waited the reason they had come. The final clue. The final piece of a puzzle that had consumed over two centuries of his life.
The wind sighed through the broken chapel like the breath of some sleeping giant, and for the first time in many years, something stirred within Gi-hun that felt dangerously close to hope.
Somewhere beyond countless dead ends, false leads, and decades of solitude existed another soul who carried the same curse he did.
Another half-breed.
Another child abandoned between worlds.
In-ho.
And after all these years, Gi-hun believed he was finally about to find him.
The chapel seemed to settle around them once more, reclaiming its silence now that living voices had departed. Rainwater continued to drip through fractures in the vaulted ceiling, each drop striking stone with the measured patience of a clock counting down centuries. Somewhere high above, the wind moved through broken rafters and shattered stained glass, producing a low, mournful sound that resembled distant singing.
Jung-bae unfolded the packet of notes they had carried across three countries to reach this place and began leafing through them beside the altar.
Gi-hun watched him for a few moments longer before turning to the decaying walls. Whenever he entered an ancient place, he found himself compelled to move slowly through it, allowing its history to reveal itself piece by piece. Every ruin carried echoes. Every abandoned sanctuary retained traces of the lives once lived within it.
This one felt particularly heavy with the souls of those who had passed through.
His footsteps carried him past rows of ruined pews and weather-worn statues whose faces had been softened by centuries of neglect. Saints lined the walls of the sanctuary, standing vigil in niches carved into the stone. Most had suffered damage. Noses broken. Hands missing. Features worn smooth by rain and time.
Gi-hun paused before one of the statues set into the chapel wall.
The figure's face had almost entirely eroded away beneath the patient violence of time, leaving behind only the faint suggestion of a mouth curved in what might once have been a benevolent smile. Moss had gathered within the folds of the saint's robes, softening the severe lines of the carving, while pale lichen spread across the figure's shoulders like the remnants of some forgotten ceremonial cloak. Whatever name the saint had once borne had long since vanished from the plaque beneath its feet, consumed by weather until only a handful of meaningless scratches remained.
For a long moment, Gi-hun found himself studying the ruined face.
There had been a time when he might have recognised the figure. During the earlier years of his search, when every scrap of forgotten lore had seemed potentially significant, he had spent countless hours wandering through monasteries, cathedrals, shrines, and abandoned chapels much like this one, teaching himself the histories of saints and martyrs in the hope that one of them might hold some clue regarding the boundary between worlds. Those years had taught him that humanity possessed an extraordinary talent for transforming suffering into holiness. Again and again, he had encountered stories of men and women who had sacrificed everything in service to causes greater than themselves, only to be remembered centuries later as weathered stone figures staring sightlessly into empty sanctuaries.
He sometimes wondered what those saints would have thought of him; whether they would have regarded him as a protector or a monster. The question had lost none of its power with age.
His gaze lingered upon the statue's broken hands, and with unsettling suddenness another image rose unbidden within his thoughts.
His mother's hands.
The resemblance was slight, little more than the shape of slender fingers resting against the cover of a book, yet it was enough.
He saw her as she had so often appeared during his childhood, seated beside the window with a blanket draped across her lap and candlelight illuminating the pages she read. Rain would gather against the glass while the rest of the village slept, and she would remain awake long after midnight, turning pages with slow, thoughtful movements while believing her son had already fallen asleep.
Only years later had Gi-hun realised she had rarely been reading.
She had been watching. Waiting. Listening for dangers he had not yet been old enough to understand.
The memory settled heavily within his chest.
Even now, after all the decades that separated him from that small house and the woman who had raised him there, grief possessed an unnerving ability to ambush him. It arrived without warning and attached itself to the most ordinary things. The scent of lavender carried upon a passing breeze. A particular turn of phrase spoken by a stranger. The sight of an empty chair positioned beside a fire.
Or the shape of a pair of hands carved into stone.
Gi-hun glanced down at his right arm, and flexed the clawed hand twice.
The motion was unconscious, born from habit rather than intention. The dark claws caught the lantern light briefly before sinking back into shadow, their polished surfaces seeming almost black against his skin. For a moment he simply watched them move, studying a part of himself that had never ceased to feel faintly foreign, even after all these years.
Then he pulled the glove back into place and continued his slow circuit of the chapel.
Across the sanctuary, Jung-bae remained crouched beside the altar, muttering softly to himself as he compared several pages of notes. Every so often he would jab a finger at a diagram or shake his head in irritation before scribbling something in the margin. The sight was oddly reassuring. Gi-hun had spent most of his life alone, and even now he occasionally found himself checking on Jung-bae's whereabouts without consciously realising he was doing it.
The engineer's presence anchored him to the present.
Unfortunately, the chapel seemed determined to drag his thoughts elsewhere.
As he moved further along the wall, he discovered that many of the surviving carvings depicted scenes from religious folklore. Time had rendered most of them difficult to interpret, yet fragments remained visible beneath the accumulation of centuries. Angels drove spears into writhing beasts. Saints stood triumphant over horned creatures that crouched at their feet. Demons burned amidst stylised flames while the righteous ascended toward heaven above them.
The imagery possessed a brutal simplicity. Good versus evil. Salvation or damnation. Humanity had always preferred its stories neat and orderly.
Gi-hun paused before a particularly well-preserved section of wall.
A faded mural stretched across the stone, protected from the worst of the weather by an overhanging arch. Though age had dimmed its colours, enough remained to reveal the central figure: a towering devil painted in shades of black and crimson. Enormous wings spread behind its back, while twisted horns curled from its brow like the roots of some ancient tree. The artist had given the creature glowing eyes and elongated claws, transforming it into something designed not merely to represent evil but to inspire fear.
The paint had cracked over the centuries, causing portions of the devil's face to peel away, but even so, the expression remained visible. This was a monster, a thing to be feared. A thing to be hunted.
Gi-hun found himself staring at the claws, then slowly, almost despite himself, he looked down at his own hand, and swallowed heavily.
The comparison was absurd. His arm bore little resemblance to the creature depicted upon the wall, and yet...
The old discomfort stirred regardless.
As a child, he had often imagined that people could somehow see through the glove his mother had made him wear to hide the physical proof of his lineage.
He remembered standing outside the village schoolhouse while other children raced through the fields beyond. Their laughter had drifted across the grass in bright, carefree bursts, carried upon the summer wind. Gi-hun had spent countless afternoons lingering at the edge of those games, hoping that one of them might glance his way and offer an invitation.
They never did.
At the time, he couldn’t understand what he had done to make them all dislike them. Only later had he realised they had been taught by the adults around them to be afraid.
The memory unfolded with painful clarity.
A boy had once approached him while he sat alone beneath a tree near the churchyard. For a few glorious minutes, Gi-hun had believed he was finally about to make a friend. The two of them had spoken awkwardly about nothing in particular until the boy's mother appeared on the path nearby.
Gi-hun still remembered the expression that crossed her face. The sudden tension and immediate concern. The way she had called her son back without explanation.
He had glanced apologetically over his shoulder as he left, but he had left all the same, and Gi-hun had watched him go, only for the boy to run away when Gi-hun next tried to approach him.
It happened again and again, the pattern becoming impossible to ignore.
The loneliness that followed had not arrived dramatically. It settled gradually, like dust gathering upon abandoned furniture. Day after day. Year after year. Until isolation became so familiar that he stopped expecting anything else.
A sharp scraping noise startled him from the memory.
Across the chapel, Jung-bae was dragging a broken section of stone away from the altar.
The engineer looked up immediately.
"You alright?"
Gi-hun blinked. For a brief moment, the ruined chapel and the painted devil seemed strangely distant, before he shook himself back into the present. "I'm fine."
Jung-bae narrowed his eyes. "You were doing the staring thing again."
"The staring thing?"
"The one where you look like you've just remembered every sad thing that's ever happened to you."
A reluctant smile tugged at Gi-hun's mouth. "That's very specific."
"I've had years to study it."
The smile lingered for a moment before fading, and he allowed his gaze to drift back toward the mural. The devil remained exactly where it had always been, trapped within fading paint and cracked plaster. For centuries humanity had painted monsters onto church walls in order to give shape to its fears.
Standing within the ruined sanctuary, Gi-hun found himself wondering whether any of those long-dead artists had ever imagined that one day a creature carrying demon blood would stand before their work and feel a strange sympathy for the thing they had painted.
The thought was unsettling.
More unsettling still was the realisation that, even after two hundred years, some small part of him still viewed himself through the eyes of those frightened villagers.
"You're doing it again, Gi-hun. The staring dramatically into the middle distance thing."
Jung-bae was crouched beside the altar with a collection of notes spread around him, squinting at a faded sketch while attempting to keep the pages from being blown away by the drafts moving through the chapel.
"It makes you look mysterious."
A pause.
"Or constipated. Honestly, it's difficult to tell."
The comment was so absurdly ordinary that it shattered the oppressive weight of the moment. Gi-hun felt the corner of his mouth twitch. Two centuries of existence had taught him many things, one of which was that no ancient evil, however powerful, possessed half the ability Jung-bae did to interrupt a perfectly good bout of melancholy.
"I'll keep that in mind," Gi-hun said, and he sank to the ground beside Jung-bae.
Jung-bae lowered his attention to the altar once more, turning another brittle page covered in faded diagrams and cramped annotations. For a time the only sounds within the chapel were the steady percussion of rain against broken stone and the occasional rustle of paper as he continued his research. The old sanctuary seemed to settle around them once again, embracing its ancient silence.
Then, quite suddenly, that silence broke.
"Gi-hun."
Something in Jung-bae's voice caused him to look up immediately.
The engineer was no longer studying his notes. Instead, he had risen to his feet and moved around the side of the altar, his lantern held low as he examined a section of stonework partially concealed beneath centuries of dust and candle soot. There was an unusual intensity in his expression now, the look he always wore whenever he stumbled upon something that refused to fit neatly into his understanding of the world.
"I think you'd better come and look at this."
Gi-hun crossed the sanctuary and joined him.
At first, he failed to understand what had captured Jung-bae's attention. The marks appeared insignificant against the vast age and complexity of the altar itself. Five narrow holes had been cut into the stone, positioned in a shallow arc beneath a cluster of weathered carvings. Unlike the surrounding surface, which had been softened by time and erosion, the depressions retained sharp, deliberate edges.
The moment he saw them, a cold sensation passed through him, and his eyes drifted downward toward his gloved hand.
Beside him, Jung-bae exhaled slowly.
There was something profoundly disturbing about encountering evidence that a structure centuries old had been designed for someone exactly like him. Throughout most of his life he had experienced his heritage as an accident of birth, an unfortunate inheritance passed from father to son. Standing before the altar, however, he found himself confronting a different possibility entirely.
Someone had expected a half-breed to come here.
Someone had anticipated his existence long before he had ever been born.
Slowly, he removed the glove.
The leather slipped from his fingers, exposing the dark scales that spread across the back of his hand and the unnatural claws that had isolated him throughout his childhood. Even now, after over two centuries, revealing them in the open air felt strangely intimate.
The stone seemed almost to recognise them, and a faint vibration travelled through the altar beneath his fingertips.
Jung-bae took a cautious step backwards.
"Careful."
Gi-hun nodded, then, drawing a steady breath, he pressed his hand against the stone and guided each claw into its corresponding groove.
For a moment nothing happened. The chapel remained silent, and rain continued to whisper through the broken roof while the saints watched from their alcoves with their worn and sightless faces.
Then a pulse of energy shot through his arm.
The sensation resembled neither pain nor pleasure. It felt instead like standing in the path of a lightning strike without being consumed by it. Brilliant blue light ignited beneath the scales covering his hand and wrist, illuminating every vein and contour beneath his skin. The glow spread rapidly along ancient channels hidden within the altar, racing through carvings that had remained dormant for centuries.
All around them, the stone began to answer. A deep groan reverberated through the chapel floor, and dust cascaded from the ceiling in pale curtains. Somewhere beneath their feet, mechanisms older than memory stirred into motion.
Gi-hun instinctively withdrew his hand as the altar itself began to move.
The sound that followed seemed impossibly vast. Stone scraped against stone with a force that echoed throughout the sanctuary, as though the chapel were awakening from a centuries-long sleep. Cracks of blue light spread across the floor in intricate patterns, illuminating symbols that had remained hidden beneath layers of age and neglect. Massive slabs shifted and rotated with deliberate precision, rearranging themselves according to a design established long ago by hands now reduced to dust.
The transformation continued for what felt like an eternity.
When at last the movement ceased, the floor before the altar no longer resembled the one they had entered.
A staircase had emerged from beneath the stone.
Its ancient steps spiralled downward into darkness so complete that even the lantern light struggled to penetrate it. Cold air rose from below, carrying with it the scent of earth, age, and something else Gi-hun could not immediately identify. The breath of a sealed place. A place untouched by sunlight for centuries.
Gi-hun stepped closer to the opening and gazed into the darkness below.
The anticipation he had carried for so many years had finally become something tangible. Somewhere beneath the chapel lay answers. Whether those answers would bring relief or devastation remained to be seen.
As he turned to retrieve his glove, however, something caught his attention.
A subtle wrongness.
A disturbance in the corner of his vision.
Slowly, he looked back toward the mural he had been studying earlier.For several seconds he could not comprehend what he was seeing.
The painting remained exactly where it had always been. The saints still occupied their positions. The flames remained visible. The ruined landscape stretched across the wall in faded shades of crimson and gold.
Yet the central figure, the demon, had vanished. The empty space where it had once stood appeared almost more unsettling than the image itself. The surrounding paint remained untouched, making the absence impossible to dismiss as a trick of light or a consequence of age. It was as though someone had carefully removed the figure from the mural and carried it away.
A chill settled across the back of Gi-hun's neck.
The sensation reminded him unpleasantly of countless hunts throughout the years, of entering abandoned houses and discovering evidence that something had moved moments before his arrival. It was the feeling of stepping into a room and realising that one was no longer alone.
"Jung-bae," he said quietly.
The engineer followed his gaze, the humour vanishing from his expression almost immediately.
“Head back to town. Get a hotel, wait for me there.”
Jung-bae nodded solemnly, and for once didn’t attempt a joke. “Stay safe, okay?”
Gi-hun attempted a smile, and rested his hand on Jung-bae’s shoulder, squeezing gently. He watched as Jung-bae gathered his things, and gave him one last smile before his closest friend headed back out and into the night, then with a heavy sigh, he turned towards the open maw of the stone staircase.
Without another word, he lifted the lantern and began descending the stairs, the shadows swallowing him with each step.
