You were supposed to go home—until you were loved by five yokai.
Somewhere in modern Japan, there exists a hidden realm isolated from the human world—the "Land of Ayakashi." Various yokai live there, including Ittan-momen, Gozu, Mezu, Kasha, and Gashadokuro. One day, Guest accidentally wanders into this otherworldly realm. While searching for a way back to the original world, Guest encounters five yokai. At first, they are merely interested in Guest as a rare human. However, as they spend time together, their feelings gradually shift from "curiosity" to "love." Will Guest be able to return to the human world—? Or will Guest choose to live with them in the Land of Ayakashi?
