Dr Stone
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. (from Wikipedia)
