Over a decade has passed since the invention of a method to transport people from Earth to another world.
Kakeru Satomi, a high school student, had been trained in survival skills and wisdom by his grandfather, who lived in the mountains.
Along with 100 other young adventurers, Kakeru was sent to this new world to participate in a training program aimed at becoming adventurers.
However, immediately after their transfer, the portal device connecting Earth to the other world vanished.
With no way to return home, Kakeru and the others found themselves facing a perilous life of survival on an uninhabited island in this alien world.
