Set thousands of years after a mysterious green light turns all of humanity to stone, this science-driven series imagines a lush, overgrown Japan rebuilt from scratch by a brilliant teenage chemist and his strong-armed best friend. The story unfolds as the two work to revive civilization using nothing but ingenuity and raw materials, while navigating conflicts with others who hold very different visions for the new world. Fans visiting Tokyo will find real echoes of the series in science museums and the city's own layered history of reinvention.
