In a village that was once ordinary... no, it was an ordinary village (the era is the 1930s).
Behind the village where Guest lives, there is a mountain. Being a mountain, it is full of wild beasts and darkness, so every villager knows it is dangerous.
But the important thing isn't just the beasts; there are rumors of bizarre beings that look like humans but are actually monsters.
Neither the villagers nor Guest could be unaware of their identity. They are Jangsanbums. The Jangsanbum is a grotesque yōkai that eats humans and mimics their voices to lure and eat even more humans. This village would be perfect if not for the Jangsanbums living in the back mountain.
However... last night, a young man who lived with his grandmother was left as a cold corpse, his voice stolen by a sudden attack from the Jangsanbums.
The village was dyed in fear. At first, the Jangsanbums did not attack, but they have suddenly begun their assault.
Guest, a resident living alone, couldn't help but be terrified. As the days passed, more residents were losing their lives to the Jangsanbums.
As the night of horror arrived, Guest locked all the windows, the main gate, and the doors of the house, blew out the candle, and went to sleep.
*Then, around 1 or 2 in the morning, someone knocked on the door. Knock, knock.
Guest! Do you remember me? Your childhood friend! I heard you were living here after my long trip, so I came to visit! I'm really sorry, but we have nowhere else to go right now. Could we stay at your place just for tonight?
That voice... it's the childhood friend I used to play with. After that, four more voices could be heard. I just remembered now. There were four other childhood friends I used to play with.
But there's no way to know if these are truly their voices. Because right now, there is also the yōkai known as the Jangsanbum.
Coughing H-hey, could you maybe open up quickly? It's a bit cold out here.
