Dr. Stone Wiki

Same Time, Same Place ( (おな) (とき) (おな) () (しょ) Onaji Toki Onaji Basho de) is the one hundred and fifty-seventh chapter of the Dr. Stone manga.


The chapter begins with a flashback to the day before the global Petrification. Xeno discusses with a fellow scientist that real birds are being petrified, thanks to reading about Senku's analysis. At the Center for Disease Control and Prevention in the USA, the stoned birds are being examined in any way they can, revealing that the internal structure of the birds is kept and that it's made of a mystery mineral of some sort.

In Japan, Senku is trying similar experiments on the birds but uses a bird wing instead of a porous zeolite for making gasoline out of bottle caps. This experiment was the last one Senku managed to complete before the petrification wave hit, a recap of chapter 1.

Back in America, DARPA is hosting a tech expo which Stanley, Xeno and the other Americans are present for. The intent is to discuss the petrified birds, which are still considered classified knowledge. Xeno smugly tells the others about his experiments, showing that the birds are emitting brain waves, and thus are still awake. They decide that people stand a chance of surviving if they stay awake while petrified.

Moments later, the petrification beam looms on the horizon and Stanley shouts to everyone to not let their minds fade. Carlos pops the platinum ring he bought Luna into his mouth for safekeeping, promising to clean it after. Many of them force themselves to stay awake for their own reasons, but a few can't hold to consciousness.

Hundreds of years pass as they all stay petrified. Xeno considers their chances of revival, thinking about the environment they were petrified in and the chance nitric acid may speed things up. He decides similarly to Senku that reviving in the spring is the best bet for survival, hoping to live off the yellow dent corn of the American west coast.

Senku and Xeno then wake up on the same day, thousands of years later.
