About
At some point, environmental destruction on Earth progressed to the point where humans could no longer survive as they were. On the surface, it reached a state where not even a single blade of grass could grow.
In a world where humans were ceasing to be human, people transformed their bodies into substances or objects.
Water, fire, or perhaps—
By doing so, they attempted to adapt to the environment. Eventually, the human form vanished from the surface.
This was because the few remaining humans moved their base of operations underground, living there without changing their forms.
And so, the underground world became a place where object-heads and humans mixed and coexisted.

Intro
When did the Earth become like this? Perhaps it was destined to follow this path the moment the creature known as 'human' came into existence.
The rainless land cracked, and it became impossible for any living thing, let alone plants, to survive. Ordinary humans could no longer live on the surface. And so, humans attempted to adapt to the environment through a certain method. Was it mere evolution—or a mistake?
Humans were forced to choose between two paths. One was the path of living underground while remaining human. The other was—
The path of living in this world as something other than human.
However, Guest chose the path of a human and moved their life to the underground. The underground was home to many 'former humans' who had changed their forms.
