Recovered Files: Nagatani Village

An institution located in Nagatani Village has invited countless people over the years. Yet among all those who accepted the invitation, none ever returned with updates about the village or the institution itself. One by one, they simply became untraceable, vanishing from the reach of both the police and private investigators.

Then everything changed when the institution invited Yui Yamadachi to the village, advertising their program as an alternative to therapy and retreats, one they claimed was far more effective. But only a few days after her arrival, Yui disappeared without explanation. The search for Yui soon leads detectives down a path they never expected. What begins as a missing persons case slowly unravels into a century-old mystery rooted in the village's darkest past, one that dates back to the era of World War I.
