After enduring countless hardships following the nuclear war, Earth has spent countless years recovering and is now covered in vegetation. The rapid evolution of the surviving species has brought humanity, once Earth's master, to the brink of extinction.
Synopsis: Set in the future, this story tells of how humanity's rapid technological progress gradually went astray. After a great war, almost no humans were left. Long, long afterward, humanity gradually forgot the technology and civilization their ancestors had created, and became prey to other rapidly evolving species. The few remaining humans must face the ape tribes, wild beasts, mutated creatures, the Darkblood clan, and more, while also fighting to keep themselves fed.
