Senku and Taiju emerge from their petrification several thousand years after everyone in the world had turned to stone. It’s up to them to rescue everyone else and restore civilization.
It's the miracle liquid made from bat guano...
...إنّه السائل المعجزة الذي يُصنع من سماد الخفافيش
Ein wahres Wunderwasser,
geboren aus Fledermauskot.
El agua milagrosa
hecha de heces de murciélago.
El agua milagrosa
hecha de heces de murciélago.
C’est de l’eau miraculeuse,
merci à la fiente de chauve-souris.
È un'acqua miracolosa nata 
dagli escrementi dei pipistrelli.
É um líquido milagroso feito
de guano de morcego...
Чудотворная вода из помёта летучих мышей.
