Stories Humans Cannot Write

I will first present a story written by an AI, and then introduce the prompts used.

Those who vanish possess their most accurate shadow only just before they disappear.

The first thing to vanish was not the flower shop woman, but the trace of rain that had been touching her left wrist.

At 6:14 AM, as the coastal elevated train crossed Tingzhou Bridge, the onboard camera captured the woman, who had a rain-dampened paper package on her lap, resting her forehead against the window. The train swayed slightly, the line of the woman's shoulder brushed against the glass, and in the very next frame, only a bouquet of flowers and a left shoe remained in the seat. The crew testified that the tips of the white lilies still held the warmth of human skin. One passenger said that no one screamed immediately. It was because, just a moment before they could scream, everyone had remembered how a person's name feels cold inside their own mouth.

That was the first officially recognized disappearance. The newspapers wrote it as a 'vacancy,' the administration called it a 'phase-separation incident,' and the hospital vaguely diagnosed it as 'retention of accompanying matter due to acute memory delay.' The citizens put it more simply: they said that person had 'slipped out.' The way they said 'slipped out' had a filthy intimacy, like a single fingernail disappearing from a drawer.

At that time, I was a record keeper at the city's Bureau of Reverberations. My job was to collect the voices left behind by those who vanished, surveillance footage, testimonies, the humidity of their clothing, and even the oxidation rate of half-eaten fruit, then arrange them chronologically to measure the shape of the void. No one truly believed it, but a void has a contour. My boss said that as long as there is a contour, one can reach a hand into it. He wore four-fingered gloves. His wife had vanished three years ago, and the following month, his own ring finger had gone missing, delayed.

Up until the seventh case, it still wore the face of coincidence.

The second case was a water tower cleaner. He vanished while leaning his body against the railing at the top of the tower, still holding the mark he had made on the morning inspection sheet. On the inspection sheet, only the last line had been crossed out with a double line.

The third case was a Japanese language teacher. She vanished in the middle of class, in front of the blackboard where she had written 'What is a metaphor?', with the chalk dust still on her fingers. In the classroom, only her cough echoed a moment late.

The fourth case was a father in the neonatal intensive care unit. He had been pressing his forehead against the glass of the incubator, counting his daughter's heart rate. What remained was a round smudge of sebum from his forehead and an untouched peach.

The fifth case was a city bus driver. He arrived at a stop, and his voice announcing the next destination cut off midway. Only the 'gi' from 'Next is, Mi-gi' remained in the bus for a long time. One of the passengers looked at the empty driver's seat and, for some reason, assumed a posture of prayer.

The sixth case was an elderly priest. He was chanting morning prayers in the rooftop chapel. Grains of salt were scattered on the altar. Even before he died, he had been preaching that the sea was made not of salt, but of memory.

The seventh case was a boy at the aquarium, who had been pressing his hand against the tank of a giant moonfish. The fish on the other side of the glass swam avoiding only the shape of his hand.

Every scene had several things in common: moisture, belongings left on the left side, white objects, and a slight discrepancy in time. The physical reaction that visited the witnesses before understanding—the realization in the back of their throats of the position of a prayer they shouldn't have known.

And that it took exactly forty-seven seconds before they could no longer remember the name.

I read the records, repeated the footage, triggered audio noise, and went to work sleep-deprived. The reason for my lack of sleep was not just work. Fuyuki had vanished eleven days ago.

Fuyuki was a linguistic engineer involved in the maintenance of the prayer basement—commonly known as the 'Well of Prayer'—deep beneath the city. The official name was longer and more shamelessly rational, but no one called it that. After a series of disasters and plagues, this city built another foundation during a period when it became impossible to count the number of the dead. It was not a power grid, nor was it water or sewage. It was a nomenclature network. A device to calculate the frequency and intensity with which someone calls another, and to smooth out the time delays of the entire city. By pouring the final voices of the deceased, the conversations left behind, station announcements, hospital room calls, lovers' voicemails, and even the temperature of the breath of a parent scolding a child into a massive prayer machine, it prevented the lost from 'ending completely,' thereby mitigating the mental collapse of the survivors and the disruption of social functions. It was a technology that was terribly arrogant and terribly kind.

Fuyuki knew better than anyone the failure of that technology.

The failure was that the device did not hold only the dead. Those who had been loved for a long time, those who were called strongly, those who had peculiar ways of being called, or parts of those who could not fully die, got caught in the linguistic grid and lingered at the bottom of the city. Legally dead, erased on paper, and with their bones cremated, only the afterimages of their names remained in public spaces. The breathing of an old lover would mix into the announcements on a rainy day. A night vending machine would prompt for change using the phrasing of a deceased mother. Everyone had experienced it at least once, and that was why, in this city, a complete mourning was somehow forbidden.

Fuyuki once said: 'Corpses rot, but calls rot differently. It's not that they don't rot. It's just slow.' I hated that way of putting it. Because within the word 'rot' was contained the scent of a future we had not yet received.

Eleven nights ago, Fuyuo came home, placed his hands on the kitchen sink, drank a glass of water, and hugged me without saying a word. There was always an order to his embraces. Left shoulder, spine, back of the head. But that night, his right hand searched the back of my neck, and his fingertips hesitated once, like a doctor who had lost track of someone's carotid artery.

"The city is starting to pray back," he said.

He vanished before I could ask him what he meant. A wet hair clip lay on the floor. The windows were closed. There was no wind. Yet, the air in the room pulsed as if someone had just spoken from the bottom of the sea.

Bureau regulations state that one must not be involved in cases concerning family. I was removed from Fuyuo's case and instead meticulously handled the disappearances of others. It was the only way I could give shape to Fuyuo's absence. The way the florist's lilies opened, the half-syllable left on a teacher's blackboard, the crescent-shaped dent a finger pressed into the surface of a peach a father held. Each disappearance was different. Yet, I realized there was the same touch behind the differences. The city wasn't stealing people; it was stroking them until they unraveled. It wasn't violent. That was what scared me even more.

From the eighth case onward, the records could no longer keep up with the speed of the disappearances.

At the scene of the tenth case, I saw a record of the future for the first time.

In the evidence storage room under the viaduct, I found an unnumbered audio cylinder. It wasn't in the Bureau's format. It still bore the seal of an old research institute. When I played it, there was static at first, followed by a pressure like a train passing deep underground, and then Fuyuo's voice.

"Don't answer. You are still on the side of the mouth."

The sound cut off there. After a short pause, another voice overlapped. It was my own voice. But I had no memory of recording it.

"It's not just those who died first who have disappeared."

The fluorescent light in the storage room flickered once. In that moment of darkness, I lost track of my own hands resting on the desk. I learned then that darkness doesn't just steal your vision; it momentarily shifts the ownership of your contours to somewhere else.

It was from the next day that reports of future timestamps began to surface within the Bureau. Security footage timecodes displayed dates three days ahead. Reports of disappearances that hadn't occurred yet were printed out. The telephone switchboard began accumulating call records that shouldn't have happened yet. An inspector of the underground power lines said that a new door for Line Zero appeared every night. Line Zero isn't on any map. Or perhaps it existed in the past but was closed after a disaster. Both explanations sounded equally suspicious.

The city had begun to lose its future, little by little.

The number of missing persons grew. An insurance agent, a woman walking with a guide dog, a hospital incinerator operator, a twelfth-floor window washer, a man who had just finished writing his divorce papers, an old man washing fish gills at the evening market, only the older sister of a pair of middle-school twins. There seemed to be a meaning to the order in which they vanished, and yet there wasn't, but it was still a sickening chain that seemed to connect somewhere through someone's silence and someone's trembling hands.

One night, in the Bureau's server room, I found a connection map of the missing. It wasn't based on family relationships, workplaces, or call logs. It was a more ambiguous, yet inescapable line that the naming network had once recorded. The florist had delivered flowers to the Japanese teacher. The teacher had taught tanka poetry to the father, who was his middle-school student. The father had donated blood to the bus driver's wife. The driver passed in front of the old priest's church every morning, and the priest had attended the final moments of the aquarium boy's grandmother. The lines branched out infinitely, and in the end, the entire city looked like a single lung. It wasn't the lonely who disappeared first. On the contrary, it was those who were deeply embedded within others who were pulled out one by one. A hole remained where they had been. The calls of someone else would flow into that hole, wearing away yet another contour.

I found my own name near the center of that diagram.

And right next to it, Fuyuo.

When I left the Bureau, it wasn't raining, but all the leaves on the street trees were wet. The only things not wet were the shadows of the pedestrians. I hadn't known that shadows could lag behind the weather more than the physical bodies themselves. Someone in the crowd waiting for the traffic light sneezed softly, and I thought it sounded exactly like the way Fuyuo's sneezes ended. The moment I thought that, three pigeons on the white line of the crosswalk began to peck at something. The white line didn't look like paint; it looked like bone.

Line Zero actually existed.

It was located in the basement of the old city hall ruins, beyond a decommissioned fire door, at the end of a long downward slope where the smell of seawater and metal mingled. The station sign had no letters, just a white board hanging there. No trains come to the platform. Instead, an announcement plays periodically from deep within the dark tunnel.

"Soon—soon—"

A broadcast that never announces a destination. A voice that only perfects the act of waiting. I walked to the edge of the platform and stood in front of the black line. My face was not reflected in the glass of the fall-prevention fence. Instead, a little late, Fuyuo was reflected. He stood there at an age before he had received a promissory note from time, neither younger nor older than when he was alive. Perhaps because it was through the glass, his lip movements preceded his voice.

"You're getting quite thin yourself."

The way he said it sounded like a medical diagnosis, and I almost laughed. If I had, I felt like my throat would have crumbled.

"Where did everyone go?"

"Nowhere. That's why it's dangerous."

Toui looked toward the darkness of the tunnel. "This city left too many of the dead behind. To protect those who remained. But the calls pile up. What piles up becomes heavy. Time is drawn to weight. The future began to sink first."

"Were the people who disappeared dead?"

"Only half. Or perhaps death was just delayed. As much as they were loved. Because they kept being called, their bodies were still pretending they hadn't ended."

"Then, is this a collection?"

"It's not such a pretty word. The city is balancing the books."

I pressed my hand against the glass. It wasn't cold. It was the temperature at which skin momentarily forgets the distinction between itself and another.

"Are you..."

Before I could finish the question, Toui shook his head.

"You too..." He cut his words off there. Not because they were interrupted, but because he chose to. To let me decide.

I noticed that many small monitors were embedded in the walls of the platform. A florist, a teacher, a father, a driver, a priest, a boy, a twin sister, a man with divorce papers, an old man washing fish. The vanished people were watching me from fragments of their daily lives. They didn't speak. There was only the movement of their lips. Little by little, I read them. Everyone was saying the same thing.

"I haven't arrived yet."

The city had been running for years on the voices of those who had not arrived. Trains were delayed, hospital wards held on, government offices functioned, lovers postponed their breakups, parents didn't have to bury their children, and incinerators survived the night. For that purpose, the calls of people who had already ended were used repeatedly underground. Death had become a public utility.

"Is that why they disappear?"

"No," Toui said.

"They aren't disappearing. They are being returned. Finally, to a single tense."

In that moment, I understood. The florist, the teacher, the father—they hadn't been taken before anyone else. Rather, they had been kept in this city longer than anyone else. By the residual heat of the time they were loved. They had failed to cross to the other side of death, their ankles still gripped by someone's call. This 'vacancy' was a cruel seizure of the city, but also a long-overdue ordering.

The terror didn't diminish in the slightest. If anything, it grew. Knowing that something resembling salvation only arrives in such an irreversible form is deeper than most despair.

"So, when did I die?"

Toui closed his eyes. There was a beat of hesitation before he blinked them shut.

"Eleven days ago. The same night as me. That night, you were the one with your hands on the sink. When I returned, your heart was already stopping. I used the device. I moored you to the side of words for a little while. Because I needed a witness."

Toui fell silent there. The way he was silent was that of someone who hadn't finished speaking. But he continued anyway.

"You can blame me."

"It's hard to blame someone who isn't flesh and blood anymore."

When I said that, Toui smiled just a little. That way of smiling was the same as when I used to burn dinner. Even in a place like this, the repetition was vulgarly precise, and that is why people are saved.

Deep in the tunnel, a sound that was neither wind nor waves swelled. It was the sign that the broadcast was beginning. Toui's outline grew thin. I said hurriedly,

"What should I do?"

"Read the names."

"Can I bring them back?"

"To ensure they don't return."

He handed me a thin terminal. When I took it, a long list of names appeared on the screen. It wasn't a list of the vanished. It was a register of the reserved dead that this city had borrowed underground. There were far more than I had imagined. More than the government figures, more than the obituary columns in the newspapers, more than the inscriptions on disaster monuments. The rows of names were as long as the distance by which prayer betrays statistics.

"Someone has to lose it correctly at least once," Toui said.

"You?"

"Me?"

"You were the record keeper. The one who measures the shape of the void. That is why you can possess a style that brings things to an end."

Style. If it were the old me, I would have laughed at the idea that such a thing could be involved in death. But now, I know. The contours of what is lost change depending on how you name them. Words do not touch the corpse, but they touch the time surrounding it.

I sat on the platform bench and began to read the names. One by one, without haste, without adding meaning, without beautification, without inserting oaths or metaphors, I simply returned the names to body temperature in my mouth, and then passed them into the air. Each time I read one, a monitor on the platform went dark. The florist's lilies closed. The teacher's chalk fell from their fingers. The father's peach slowly turned brown. The priest's salt grew damp. The traces of the boy's hands vanished from the glass. Every delay returned to its original speed.

Many times during the process, I started to look for where my own name was. I did not look. If I were to find it, it would still be my future. Until it is read, it continues to erode someone else's present.

I do not know how much time passed. On Track Zero, the hands of the clock did not move; instead, breathing was divided like chapters. By the time I finished reading, the name of the station had faintly emerged on the white board of the platform. Even though it was a string of characters I had never seen before, for some reason, it felt nostalgic. Perhaps it is a place name that can only be read after death.

I read Toui's name second to last.

He nodded from beyond the glass. That movement alone lingered longer than his body.

"With this, I will finally stop being late," he said.

"Is not being late such a good thing?"

"It is terribly lonely. But, as a way of rotting, it is correct."

I read the one name that remained at the end.

The moment I pronounced it, the air on the platform became slightly lighter. It was as if ears that had been blocked for a long time had finally popped, and I heard the sound of the sea in the distance. Only the wind from which no train would come blew from deep within the tunnel. As I tried to stand up, I noticed that the sensation in my left foot had vanished first. Looking down, one shoe remained on the floor. It had a luster as if it had been dampened by rain.

It would be a lie to say I was not afraid. Fear belonged to the body until the very end. That is why, as I faded, I understood. When people die, they do not become free from their spirit. Rather, until the very last moment, they are bound by the tiny habits of the body—the hangnail on a fingertip, the heaviness of the stomach, the roughness behind the teeth. The delicacy of that restraint is what is closest to love.

The platform announcement chimed. This time, there was a destination.

"All trains will soon return to normal operation."

The voice was not Toui's. It was not the florist's, the teacher's, or the priest's. It was a mixture of many vanished voices, the voice of the city itself, which no longer belonged to anyone. Tomorrow's first train will pass over the dead who have become a public voice. No one will notice, and by not noticing, they will be saved. The hospital will greet the morning, fish will be lined up at the market, and in a classroom without a language teacher, another teacher will teach "metaphor." Words will delay someone again, and send someone else off again. Even so, at least tonight, the death that had been borrowed underground was returned.

Finally, I thought about the meaning of the word prayer. It is not a wish. It is not salvation. It is giving a time to that which does not arrive. It is calling the name of the one who is late, while knowing they are late. Only within that inaccuracy can people touch one another.

When my vision began to turn white, I felt strangely relieved. Only that which is irreversible is truly completed. There are moments when only what is completed looks beautiful. It is dangerous to believe in that beauty. But if it were not dangerous, prayer would just be a habit.

On the surface, it is probably already starting to rain. What gets wet is the pavement, the street trees, the roof of the bus stop, people's shoulders, and the shadows that have finally regained their original time. Without seeing it, I decided that I had seen it. We have, indeed, loved a city enough to be able to pretend we saw it.
