Summary
The Kazuha brothers stood at the apex of modern Japan: Takuya, a visionary architect and politician; Inori, an obsessive chemical engineering prodigy; and Kaguya, a cold, calculating surgeon.
But when a targeted assassination forces their car to crash into a mysterious, glowing machine, they awaken beneath the colossal canopy of an alien, prehistoric jungle. Transported to a brutal world filled with towering predators, active-camouflage wolves, and hostile primates, they quickly realize a chilling truth: humans are the weakest link on the food chain.
There is no magic to save them. There are no game-like stats or divine blessings. But the brothers don’t need magic—they have science.
Armed with nothing but a titanium pen, a Zippo lighter, a scalpel, and the combined sum of Earth’s greatest technological advancements, the brothers declare a silent war on this primitive world. Takuya will engineer their societal rise, Inori will trigger an industrial age of steam and steel, and Kaguya will dissect the alien biology to conquer death itself.
They won’t just survive the wilderness; they will forge a modern utopia from the dirt up. The primitive world is about to meet the crushing weight of modern science.
