As Ryo was approaching the strange house in the absolute darkness of the mountains, that flickering orange glow felt like a miracle.
In the void of the night, light was more than a guide. It was hope.
But as he drew closer, his ears began to pick up a sound that made that hope curdle.
Cling... Cling... Cling...
It was rhythmic. Cold. Precise.
To anyone else, it was just a blacksmith at work.
To Ryo, whose hearing could peel back the layers of reality, each strike felt like a hammer hitting his own teeth.
The vibration wasn't "hollow" like normal iron. It sounded... dense. Heavy. Like a heartbeat made of frozen metal.
Ryo stumbled out of the treeline.
His modern sneakers were caked in freezing mud. His oversized hoodie was soaked, clinging to his shivering frame.
Before him sat a small, open-fronted shack.
Inside, a man was hunched over an anvil. He wore a heavy, indigo-dyed robe, his sleeves tied back with white cords.
He didn't look up.
Cling.
A shower of sparks danced into the freezing air.
Cling.
Ryo stopped ten meters away, his breath coming out in ragged white clouds.
"Help..." his voice was a dry croak. "Please... I need a phone. I'm lost."
The man stopped mid-swing.
The silence that followed was suffocating.
Ryo could hear the man's breathing. It was slow. Deep. Controlled.
It sounded like the bellows of a forge—mechanical and powerful.
"A phone?" the man asked.
His voice was gravelly, aged, but carried a strange resonance that made Ryo's inner ear ache.
He spoke a dialect of Japanese that Ryo barely understood. It was archaic. Sharp. Every syllable felt like it was being carved out of wood.
The man turned his head slightly. He wasn't looking at Ryo's face.
He was looking at Ryo's clothes.
"What manner of beggar are you?" the man asked.
"Those garments... that fabric. It looks like the skin of a dead beast, yet it shines like silk."
Ryo looked down at his polyester hoodie. To him, it was a twenty-dollar garment.
To a man in 1912, it was an alien artifact.
"I... I'm from Tokyo," Ryo stammered, stepping closer to the warmth of the fire. "I was in Shibuya. There was a sound, and then everything changed."
"Shibuya?"
The man finally turned fully. His face was weathered, like a mountain path.
"There is no city called Shibuya that produces people like you. You smell of strange oils... and fake air."
The man stepped toward him, holding a glowing rod of steel with long tongs.
"And your ears," the man narrowed his eyes. "They are bleeding."
Ryo touched his earlobes. His fingers came away red.
The transition—the sound that had ripped him out of his world—had burst the capillaries in his ears.
"Listen to me," Ryo grabbed the man's arm, desperate. "I heard something back there. In the woods. It was... eating. I think someone is hurt."
The blacksmith's expression shifted instantly.
The curiosity vanished. It was replaced by a cold, sharpened stillness.
"What did it sound like?" the man whispered.
Ryo closed his eyes. The memory of the sound vibrated in his skull.
"Like gristle," Ryo said, his voice trembling. "Like someone was grinding wet stones together. But it had a rhythm. A heavy, slow pulse."
The blacksmith dropped the glowing steel.
It hissed as it hit the snow, sending a cloud of steam into the night.
"Get inside," the man ordered, grabbing Ryo by the collar. "Now!"
"Wait, what's happening? Is it a bear?"
"A bear doesn't grind bones to hear the music," the blacksmith spat.
He reached behind a wooden pillar and pulled out something wrapped in tattered cloth.
He unwrapped it with a single, fluid motion.
It was a sword.
But not like the ones Ryo had seen in museums. This blade was dark, almost charcoal grey. It didn't reflect the firelight.
It seemed to absorb it.
"Don't speak," the man commanded. "Don't even breathe loudly."
Ryo huddled in the corner of the forge, his heart hammering against his ribs.
He tried to tune it out, but his hearing wouldn't let him.
He focused on the forest outside.
The wind had died down.
The snow had stopped falling.
And then, he heard it.
Thump.
Something heavy had landed on the roof of the shack.
Thump.
It was moving. Slowly. Not like an animal, but like something trying to mimic the weight of a human.
Then came the sound that broke Ryo's mind.
It was a voice. But the vocal cords sounded like they were made of wet leather.
"I can hear your heart, little bird," the voice rasped from above the ceiling. "It sounds so... delicious."
Ryo looked up.
A hand—grey, long-clawed, and pulsating with black veins—reached through the gap
