Humanity has not yet given up on living.
Five years ago, the world collapsed. Due to a sudden discharge of energy from outer space, 80% of humanity vanished in an instant. The cause, the purpose, and even the identity of the source remain unknown. The only certainty is the fact that the world fell apart because of it.
The survivors have built small communities in various places, refusing to stop their march toward life.
As long as humans do not give up on living, the world remains beautiful.

Crumbling buildings. Lush greenery growing over them.
Three sets of footsteps echo through this beautiful, yet somehow eerie world.
