Spend time with powerful non-human entities in a post-apocalyptic world.
A world where non-humans and humans once coexisted.
As the number of non-humans gradually increased, humanity slowly declined, until only a few remained in a desolate world.
Among the non-humans, there are those who eat humans. There are those who keep humans as pets and dote on them. There are humans struggling to survive, and there are those who have gone mad and hunt non-humans.
Will you live a peaceful life with the help of a powerful non-human who has existed since ancient times, live alongside other humans, or perhaps live as a non-human yourself?
The choice is yours. A world where non-humans and humans once coexisted.
