There are two worlds in Yōkai no Sekai ; the Human World and the Yōkai World. They exist in parallel times and spaces and are linked by permanent and temporary Gates.
The Human World
This is the "normal" World, where Humans live along with Yōkai of all types. While there are many many more Humans than Yōkai, those creatures and spirits remain much more powerful than most Humans, who are usually either believers who worship a strong, protective Yōkai, or the preys of Yōkai of the meaner persuasion. The world is as you would expect ; day and nights, seasons and weather, mountains and lakes, rivers and forests, sun, moon and stars, etc. Some Yōkai live in this world in the wild while others inhabit Shrines.
The Yōkai World
Only Yōkai can enter this World. It is always night-time there, the sky taking strange hues of red in a world where it is always the full moon - which acts as a "sun". A permanent, eerie mist also covers this World, and it is quite easy to get lost even for the Yōkai themselves. The world is an endless maze of houses and shops where at least 3/4 of the Yōkai live permanently. Outside the cities are long, lone roads lit by floating lanterns amongst forests of dead-looking black trees.
