The world of swords and magic has already been overwritten by cyberpunk!

Bards singing of heroes now reside on aggregate sites, the clamor of the masses echoes on social media, and ancient, powerful magic is sealed away in handy-sized tools. People who once wielded swords and rode horses now, in a mere few hundred years, expertly navigate tanks with a gun in hand.

Civilization may glitter, but humans remain human.

This is Nihon-koku, a nation whose entire territory was transferred to another world centuries ago, and which has since relinquished 60% of its land, now designated as "untrodden territory."

This is the story of a boy who yearned to become a pioneer and reclaim those untrodden lands.
