In a world where humanity is turned to stone by a mysterious green light, Hanako Kanroji finds herself trapped in darkness for thousands of years. Her consciousness flickers between despair, fragmented memories, and an unyielding desire to survive. When she finally awakens, she is met with an unfamiliar, untamed world-a stone forest where humanity has long vanished.
Struggling to adapt, Hanako discovers that she is not alone. Among the scattered petrified remains of people, one person stands out: Senku Ishigami, a genius with a scientific mind and an unshakable determination to rebuild civilization. As fate intertwines their paths, Hanako must confront her own fears and insecurities while striving to become a part of this "new world."
Together, they face countless challenges: reviving others, navigating the dangers of the wild, and unraveling the mystery behind humanity's petrification. Amid the struggle, Hanako is torn between the remnants of her past feelings for Senku and her newfound resolve to contribute to the rebirth of humanity.
With science as their weapon and hope as their beacon, can Hanako and Senku bring humanity back from the brink of extinction? And in this stone world, will they find their place in a future they must forge together?
