The advanced society that relied on electricity collapsed in an instant when meteorites crashed into Earth's surface, shutting down all power grids around Tokyo. In the ensuing chaos, Kenshi Ori, a reclusive inventor living in the mountains of Okutama, finds his carefully isolated life upended. A mechanical genius who prefers machines to people, Kenshi once made a quiet living crafting intricate devices from his workshop. When a meteorite lands in his garden, he carves it into a wand out of idle curiosity. To his astonishment, the meteorite has imbued his creation with magical energy. Humanity has lost electricity but gained magic in return.

Now Kenshi must step beyond the safety of his workshop. His handmade wand could be the key to a new kind of power in a world where technology is gone and magic has taken its place. As civilization collapses and chaos spreads, this reluctant loner must use his unusual talents to survive. The story follows his journey from a shut-in inventor to someone who must navigate a post-apocalyptic landscape where magical technology and elemental magic reign supreme. Along the way, he discovers that the meteorites that destroyed the old world have sparked an entirely different evolutionary path for humanity, blending fantasy with a fresh take on the post-apocalyptic genre. Notable narrative arcs include Kenshi's initial isolation, his first experiments with magic, his gradual emergence into a broken society, and his growing role as an unlikely hero wielding the power of both science and sorcery.
