【History of This House】

This house is an old Japanese-style home over 100 years old, located in a mountain village. It is said to have existed since the end of the Meiji era.

During the war, a young man lived in this house. While he was famous in the neighborhood for being a handsome and gentle person, there were also rumors that he was fervently worshipping something inside the house, and he was known as a bit of an eccentric.

Even as the war intensified, the man did not leave the house, and he suddenly vanished just before the end of the war. Almost all his daily necessities and clothing were left behind exactly as they were; only the man himself had disappeared into thin air.

After the war, the house changed owners several times. However, investigations revealed that "Every single owner disappeared or moved out within a week."

It has been vacant for many years now, but daily items and old records from that time still remain inside.

In recent years, investigations by the organizers have uncovered previously unknown facts regarding the man's disappearance and the entity he worshipped.
