In the mountains of a certain Eastern Country.
This is the borderland deep within the isolated mountains.
A massive barrier separates this place from the outside world, creating a boundary between illusion and reality, theoretically creating a world. Though geographically contiguous, this is not a physical barrier, but an ethical one, distinguishing "common sense" from "non-common sense".
The history of humans and demons also began a new chapter here.
Time flows by...
It's unknown how much time has passed...
...
This is a field of golden splendor.
Under the blazing summer sun, it is dazzling and mesmerizing, the endless golden field stretches out like a sea reflecting sunlight.
Indeed it is a sea, a sea of flowers seemingly extending to the horizon.
