Wikipedia describes the series' plot as:
Beginning in April 5738 A.D., it's been over 3,700 years since a mysterious flash of light petrified nearly all human life. A 16-year-old genius named Senkū Ishigami is suddenly revived to find himself in a world where all traces of human civilization have been eroded by time. Senkū sets up a base-camp and begins to study the petrified humans in order to determine the cause of the event, as well as a cure.

Over the next 6 months, Senkū learns his revival was made possible with nitric acid. With this discovery, he develops a compound that will allow him to instantly revive others. He begins by reviving his friend Taiju Ōki, their classmate Yuzuriha Ogawa, and a famous martial artist named Tsukasa Shishiō, with the goal of rebuilding civilization with a focus on science.

Tsukasa ultimately reveals that he opposes Senkū's idea of forming a new scientific civilization, believing the old world was tainted and should not be restored. Instead, he desires to establish a new world order based on power and strength, going so far as to destroy any petrified adults he encounters in order to prevent them from interfering with his goals.

After extorting the formula for the revival compound from Senkū, Tsukasa attempts to murder him when he realized that Senkū knows how to create weapons that he cannot defend against. Believing he successfully killed Senkū, Tsukasa leaves to begin establishing his own faction in the Stone World.

After recovering from his near death experience, Senkū discovers a tribe of people already living on the planet and sees this as an opportunity to create his Kingdom of Science. These people are originally hesitant, but eventually learn the benefits that science can bring to their survival. Over time, Senkū becomes more trusted by the tribe, eventually being taught of their past - where he discovers that the village was started by his father figure, along with 5 other astronauts, whom were unaffected due to being in space at the time of the petrification event.

Together, with his new allies and friends, Senkū's Kingdom of Science engages in a war with Tsukasa's clan, ultimately emerging victorious and affirming themselves as a force to be reckoned with. After the victory they discover that Senkū's adopted father had left precious metals which can be used as catalysts to mass produce revival fluid in the nearby island which is now inhabited by a tribe known as the Petrification Kingdom, who possess the device used to petrify the world so long ago.
