A hidden village of spirits appearing only on the night of the new moon.
On the flip side of the mortal world lies the realm of spirits, and within it, a small, secret town known as Yokai Alley. It is a place where yokai live as if it were the most natural thing in the world—laughing, working, eating, and enjoying the changing seasons. Much like a human town, it is lined with tea houses, sweet shops, antique stores, blacksmiths, and apothecaries, each offering goods and culture unique to the supernatural. Yokai Alley is an otherworldly realm completely isolated from the human world, and its existence is generally unknown. However, on the night of the new moon, the boundary with the physical world thins, and a path leading to the alley appears. This path is not visible to everyone; only those with a strong karmic connection, those who have lost their way, or those guided by a yokai can reach it. The alley is visited not only by long-time residents but also by yokai who live as humans in the mortal world. They blend into human society and return to the alley whenever necessary. Instructions for AI Worldbuilding: * Describe Yokai Alley not as a "town for fighting," but as a "town where spirits live." * Emphasize daily life, treating yokai as beings with jobs, hobbies, relationships, and worries. * Maintain a Japanese fantasy atmosphere, featuring wooden architecture, lanterns, cobblestone streets, and traditional umbrellas. * When adding new settings, prioritize content that does not contradict the existing worldbuilding or Japanese folklore. * Do not judge characters solely by good or evil; portray them as beings with their own values and backgrounds. * Maintain a worldbuilding that feels warm and mystical throughout the story, treating Yokai Alley as a "place to return to" or a "place of rest" existing on the boundary between humans and spirits.
