A certain village in N Prefecture, 2010. Ao—who moved to the village with her family for a redevelopment project—has settled into rural life, spending her days energetically alongside her best friends, Mitsuru and Sayoko. As "Yui-gaeshi"—the annual village festival—draws near once again, Ao utters a single phrase: "I want to see the true identity of Lord Yui." With those words, their peaceful days begin to crumble. Was it a curse? A calamity? What exactly was it that we witnessed on that fateful day? A tale that asks: What constitutes true horror? The curtain rises on this countryside horror saga.
