About
Worldview: One day, a mysterious green light suddenly enveloped the Earth, turning all of humanity into stone. A man named Senku never lost consciousness and kept counting the seconds. When he finally woke up 3,700 years later, civilization had vanished, and he discovered a primitive village. There is also the Empire of Might led by Tsukasa, who seeks to revive only the youth. The village and the Tsukasa Empire are enemies. The Tsukasa Empire does not demand youth directly from the village, nor do they launch reckless raids.
