In 2019, a mysterious flash suddenly petrifies ostensibly all humans. The human race is frozen in stone for 3,700 years until in April 5738, when 16-year-old prodigy Senku Ishigami is suddenly revived to find himself in a world where all traces of human civilization have been eroded by time. Senku 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 six months, Senku’s friend Taiju Oki wakes up and Senku learns their revival was made possible with nitric acid. With this discovery, they develop a compound that will allow them to instantly revive others. They begin by reviving a famous high school martial artist named Tsukasa Shishio and their classmate Yuzuriha Ogawa with the goal of rebuilding civilization with a focus on science.
Tsukasa ultimately reveals that he opposes Senku’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 Senku, Tsukasa attempts to murder him when he realized that Senku knows how to create weapons that he cannot defend against. Believing he successfully killed Senku, Tsukasa leaves to begin establishing his own faction in the Stone World.
After recovering from his near death experience, Senku 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, Senku becomes more trusted by the tribe, eventually being taught of their past where he discovers that the village was started by his adoptive father Byakuya, along with five other astronauts, who were unaffected due to being in the International Space Station at the time of the petrification event. Together with his new allies and friends, Senku’s Kingdom of Science engages in a war with the Tsukasa Empire, ultimately emerging victorious and affirming themselves as a force to be reckoned with. After the victory, they discover that Senku’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.
Episode description:
Taiju begins freediving to retrieve the statues. Kaseki is revived and with his help Senku makes the drone propeller by coating feathers in plastic attached to a fidget spinner. Taiju collects all the statues, including an extra statue that has been petrified for years. In the citadel Ginro is chosen to marry the Master. Moz deduces Kohaku is the infiltrator. Terrified of the Masters impending molestation Ginro decides to use a gas bomb Senku made from vinegar, alcohol and sulphuric acid to cause the Master intense mental confusion. Entering the Master’s room Ginro encounters Ibara who insists all girls traditionally must satisfy him first before marrying the Master. Exposed, Kohaku begins fighting Moz. Ginro neutralises Ibara with the gas and discovers the Master was petrified years ago so Ibara could secretly take over. Moz is attracted to Kohaku for her beauty and strength and is irritated she rejects him for lacking honour. Ginro is fatally stabbed by Ibara but manages to tell Kohaku the Master was almost certainly Soyuz’ father. To save his life Kohaku provokes Kirisame into petrifying them both, trusting Senku to find and revive them. As the weapon activates Kohaku sees it clearly for the first time, a complex scientific device she dubs the Medusa, from a story Senku told her of the mythical greek monster.
