Carboniferous Science
In the depths of a Tokyo laboratory, seventeen-year-old genius Sekitanki Hankō suru hito has everything—awards, recognition, respect—yet feels utterly hollow. His groundbreaking discovery of stable temporal distortions promises to revolutionize physics, but for him, it's just another achievement that fails to fill the void consuming him from within.
When the world's first time machine activates, Sekitanki volunteers as its pilot, seeking not glory but meaning—something, anything to make him feel alive. His destination: the Carboniferous Period, 359 million years before humanity's existence.
Within minutes of arrival, disaster strikes. A centipede the size of a train car destroys his only way home, leaving him stranded in an alien world where dragonflies have six-meter wingspans, millipedes move like living tanks, and scorpions hunt in coordinated swarms. Armed with nothing but his intellect and desperation, Sekitanki must transform from isolated prodigy into savage survivor.
As weeks blur into nightmares of blood and chitin, he crafts weapons from the bones of his kills, cauterizes his own infected flesh, and battles prehistoric apex predators with improvised technology that shouldn't exist. Each fight strips away another layer of civilization, revealing something harder beneath—the stubborn human will to survive at any cost.
But survival alone isn't enough. Haunted by memories of the family he abandoned and the emptiness that drove him to this desperate escape, Sekitanki begins rebuilding his time machine from impossible materials. His goal: return home and finally understand what matters.
Yet when his improvised device finally activates, corrupted temporal coordinates throw him not to modern Tokyo, but to feudal Japan's Kamakura Period—an era of samurai, honor, and human violence more terrifying than any prehistoric monster.
CARBONIFEROUS SCIENCE is a dark shōnen epic blending emotional devastation with brutal survival action, exploring genius, depression, and what it truly means to fight for something beyond yourself.
