3. 呼号重演

The fog rolled down from the ridge like a living thing, thick and gray and heavy with the smell of rotten eggs. Sakuma tied a wet cloth over his nose and mouth, pulled on his gloves, and stepped out of the schoolhouse at the stroke of midnight. He carried a small flashlight, a compass, Tanaka's map, and the silk fragment in his inner pocket. His boots crunched on the frozen snow, but the fog muffled every sound, wrapping the village in a cocoon of silence.

He followed the map toward the second shaft, the one Tanaka had marked with a faint cross. The path climbed steeply through the pines, and the sulfur smell grew stronger with each step. He passed the shrine, where the rope hung motionless in the still air, and continued upward. After twenty minutes, the trees thinned, and he stood before a concrete slab cracked open like a broken tooth. The opening was narrow, barely two feet wide, but enough for a man to squeeze through.

He shone his light into the darkness. The beam revealed a steep slope of rubble, leading down into a black void. He dropped a stone and counted—five seconds before it struck something. Deep, but not bottomless. He secured a rope to a nearby pine, tied it around his waist, and lowered himself into the shaft.

The air grew warmer as he descended, the sulfur smell sharpening into a chemical burn that stung his eyes. He kept the cloth pressed to his face and moved slowly, testing each foothold. The walls were rough, streaked with yellow crystals that glittered in the flashlight beam. Old timbers supported the roof, some of them cracked, some of them fresh—newly replaced, he noticed, with clean cuts and modern nails.

At the bottom, a horizontal tunnel stretched into the mountain. He followed it for a hundred meters, his footsteps echoing off the walls. The tunnel branched twice; he chose the left fork, guided by a faint draft of air that carried not just sulfur but something else—a trace of woodsmoke, and beneath it, the metallic tang of cooking oil.

He rounded a bend and stopped. A small chamber opened before him, carved out of the rock, furnished with a cot, a kerosene stove, a stack of canned goods, and a shelf of books. A single candle flickered on a crate, casting dancing shadows across the walls. And on the cot, wrapped in a thick blanket, sat a figure.

The figure was small and thin, with a face that had been ravaged by time and acid. The skin on his cheeks was mottled, scarred into a patchwork of pink and grey, and his left eye was a cloudy white. His hair was sparse and white, and his hands, resting on his knees, were gnarled with arthritis. But his right eye was clear and sharp, and it fixed on Sakuma with an intensity that had not dimmed in forty years.

"You found me," the old man said. His voice was a rasp, as if his throat had been scoured with sandpaper. "I wondered who would come first—him or someone like you."

Sakuma lowered the cloth. "Are you Tanaka Haruki?"

The old man smiled, revealing a row of yellowed teeth. "That name died in the fog. But yes, that was me. The boy who killed his father. The boy who walked into the poison and refused to die." He coughed, a wet, rattling sound, and wiped his mouth with a rag. "I survived because my sister—little Satsuki—she followed me that night. She was only eight, but she had watched me tie the rope, and she knew where I was going. She dragged me into a side tunnel where the air was cleaner, and she brought me water and rice for three days until I could stand. Then she went back to the village and pretended I was dead."

Sakuma sat on a crate, his legs suddenly weak. "Your sister—Satsuki—she later left the village?"

"Two years later. She was ten, and she walked out on a summer morning, barefoot, with nothing but a bundle of clothes. No one stopped her. They were glad to see the shame leave." The old man's eye glistened. "She went to Nagano, changed her name, married a schoolteacher, and had a son. She named him Haruki—after me. And when he was grown, she told him the whole story. She sent him back here to find the truth."

"He found it," Sakuma said. "He found the shrine, the platform, the village's rule. But he didn't expose it. He stayed."

The old man nodded slowly. "He stayed because he saw what I had become. A ghost. A creature of the dark. He saw me hiding in this hole, breathing poison, waiting for death. And he decided that he would not let my suffering be meaningless. He would become the village's doctor, and he would watch. He would guard the secret, because if the secret came out, then my mother's name—Satsuki—would be dragged through the mud. She had already endured so much. He could not bear to add to her shame."

"But by guarding the secret, he became part of the system. He killed Oba. He killed Miki. He would have killed me."

The old man's face twisted. "Yes. He killed them. But not because he hated them. Because he feared that the truth would destroy the only thing he had left—his mother's memory. He told me once: 'I will keep this village alive, even if it is rotten, because my mother believed that one day it would heal.' But it never healed. It only grew more rotten."

Sakuma pulled out the silk fragment and unfolded it. "I found this. Your sister sewed your name into it, buried it under a persimmon tree. She never forgot you."

The old man reached out with trembling fingers and touched the cloth. His face crumbled, and a low moan escaped his throat. "Satsuki. My little Satsuki. She was the only good thing in that place." He clutched the silk to his chest, and for a long moment, the only sound was his ragged breathing.

Then a noise came from the tunnel—a scrape of boots on rock, and voices, low and urgent. The old man's eye snapped open. "They are here. He knows. He always knows." He pushed Sakuma toward a narrow crevice at the back of the chamber. "Go. There is a passage that leads to the third shaft. It will take you out of the mountain. I will hold them here."

Sakuma hesitated. "Come with me. You can testify. You are the living proof."

The old man shook his head. "I am not proof. I am the wound that never closed. If I leave, the village will fall apart, and that will destroy Satsuki's memory. She loved this place, even after everything. She wanted it to survive." He placed a hand on Sakuma's chest. "Go. Tell the world what you have seen. But do not let them find me. I am already dead."

Sakuma squeezed through the crevice, scraping his shoulders against the rough stone. He crawled for what felt like an hour, the tunnel narrowing until he was on his belly, dragging himself forward by his elbows. The air grew colder, and the sulfur smell faded. He emerged into a small cave, where a shaft of moonlight fell through a crack in the ceiling. He climbed the rubble, squeezed through the crack, and found himself outside, halfway up the ridge, with the village glittering far below.

He had barely taken three steps when a hand grabbed his collar and yanked him back. He spun, raising his flashlight like a weapon, and found himself facing Tanaka Kohei, flanked by two other villagers—the fisherman and a wiry man with a mining lamp on his helmet.

Tanaka's face was calm, almost serene. "You went into the mountain. You spoke to him. I told you to stay out of the fog."

Sakuma held his ground. "I know everything. I have the silk fragment, the letter from Oba, the photographs. I have already transmitted copies to my office. If anything happens to me, the entire village will be investigated."

Tanaka's smile did not waver. "You transmitted nothing. There is no signal here, and the telephone line to the prefecture was cut three years ago. I made sure of that." He stepped closer. "You are a resourceful man, Sakuma-san. But you are alone."

The two villagers advanced, their boots crunching on the snow. Sakuma backed toward the edge of a drop-off, his heart pounding. He reached into his pocket and pulled out his last card—the silk fragment, which he had kept in his hand. "This is proof. Your mother's name is sewn into it. If you destroy me, you destroy her legacy."

For the first time, Tanaka's composure cracked. His eyes darted to the cloth, and his mouth tightened. "My mother—she suffered enough. She did not need to see her son become a jailer."

"You did not become a jailer. You became a killer."

The words hung in the air. Tanaka's hand trembled, and for a moment, Sakuma saw the boy who had been sent into the fog—not the original Haruki, but the nephew, the son of Satsuki, who had come with hope and had been swallowed by despair.

Then the mountain roared.

A low rumble, building into a thunderous crack, echoed from the peak. Sakuma looked up and saw a cascade of snow and rock plunging down the slope, straight toward the village. The fog had hidden the unstable cornice above the third shaft, and the explosion of the old dynamite—the old man had set it off, Sakuma realized, to bury the evidence—had triggered an avalanche.

The two villagers screamed and ran. Tanaka stood frozen, staring at the wall of white that descended with terrifying speed. Sakuma grabbed his arm and dragged him sideways, toward a cluster of boulders that offered some shelter. They dove behind the rocks just as the avalanche roared past, burying the path, the shrine, and half the village under a torrent of snow and debris.

Silence fell, thick and suffocating. Sakuma coughed, spat out snow, and looked at Tanaka, who lay beside him, his face pale and streaked with blood from a gash on his forehead.

"He did it," Tanaka whispered. "Haruki-san. He blew the mine. He knew I would not let you leave."

Sakuma stared at the buried valley. The village was gone—not destroyed, but entombed, its roofs, its wells, its secrets all hidden under a fresh layer of white. The clinic, the general store, the shrine—all gone. And with them, the old man, the proof, and the last living witness to the original crime.

Tanaka struggled to sit up. "I have to find him. He is my mother's brother. He is my blood."

"No," Sakuma said, his voice hollow. "He wanted to end it. He ended it."

They stood together on the edge of the frozen wreckage, two strangers bound by a story they could not fully tell. Sakuma pulled out his phone—still no signal—and looked at the sky. A faint drone, growing louder, buzzed from the east. A helicopter, perhaps. Or perhaps just the wind, playing tricks.

But Tanaka heard it too. He turned to Sakuma, and for the first time, his eyes held no calculation, no malice—only exhaustion. "They will come. They will dig. And they will ask what happened here. What will you tell them?"

Sakuma looked at the silk fragment in his hand, then at the white expanse that had swallowed a village and a century of suffering. "I will tell them the truth. All of it."

Tanaka laughed, a bitter, broken sound. "The truth? No one will believe the truth. They will say it is a tale, a legend, a mountain madness. They will bury it deeper than the snow."

Sakuma folded the silk and placed it back in his pocket. "Then I will dig it up again. Over and over, until someone listens."

The helicopter grew louder, its rotors carving the fog into shreds. Sakuma raised his arm and waved, a slow, deliberate motion. Beside him, Tanaka did not move. He simply stood, staring at the buried village, his face a mask of loss and release.

And in the distance, muffled by the snow, Sakuma heard it again—the lullaby, rising and falling, wordless and eternal. But this time, it was not coming from the mountain. It was coming from within his own memory, a ghost that had taken root in his mind, a seed that would never stop growing.

He knew, with a certainty that chilled him more than the cold, that he had not escaped the village. He had carried it with him, in his lungs, in his heart, in the silk that pressed against his chest. And wherever he went, the fog would follow.
