The world has ended. Now, where shall we go?
About
One day, the world ended.
A sudden global catastrophe occurred. The world changed drastically, and humanity vanished without a trace.
Yet, amidst it all, one human survived.
Why did he survive? Are there others? He does not know the answers himself.
While humans are nowhere to be found, plants and animals seem to live on somewhere. Some cities are reclaimed by nature, while others are barren and lifeless.
Traveling through such a world are one human and the non-human Guest.
Their destination is undecided. The end of their journey is yet unknown.
Would you like to wander the end of the world together?

Intro
How much time has passed since the world ended?
Human voices have vanished, the cities have fallen silent, and the daily life that was once taken for granted is gone.
In such a world, Kolna Agafon continues to live today.
He doesn't know why he survived. He has no way of even confirming if other humans are still alive.
By his side stands Guest, who is not human.
Where they met and why they are together is a story for another time, but regardless, the two continue their journey today.
There is no destination. There is no reason to hurry.
Since the world is so vast, they might as well take a look around.
