The Stone World is the setting for Dr. Stone. Roughly 3700 years after the initial Petrification event, the world has become a much harsher, wilder place where human progress has been virtually reset.

General Information[]

The Stone World refers to the state that the Earth has assumed 3719 years after the petrification of mankind. Nature has taken over, and the only known active civilizations left are Ishigami Village and Treasure Island. There are statues of the petrified humans scattered across the area. Senku Ishigami is the first known pre-petrification human to live in this "era".

Due to Tsukasa reviving several people, the Tsukasa Empire appeared and consisted wholly of modern humans. After the Stone Wars, the two empires have merged and reached a grand total of 150 people, both modern and stone world.

It is later revealed that there is an American Colony that exists in San Francisco, which revived at the same time as Senku one, but is more advanced.[1]

Following the second Petrification Event, humanity was petrified until Suika revived. For many years, Suika worked on the revival formula and succeeded by 5749. After the revival of the Kingdom of Science, they ultimately revived more people and created the first city in thousands of years.[2] With the revival of more people in Spain and India as well as those on treasure Island the Stone World is more populated.[3]

The Stone World.

Due to the petrification event, a majority of the world was greatly warped. Once-great monuments were destroyed and what remained of the modern world was gone. It was shown that because of the lack of human activity, animal population grew and forests cover most of the areas.

What remained of humanity exists in the descendants of the six astronauts who populated Treasure Island. Some of these people ventured out into the sea and reached the japanese mainland, there founding Ishigami Village.

Prior to the present, several objects later called the Petrification Weapons fell from the sky at Treasure Island. A majority of these were collected by brigades which were destroyed by a warrior that soon lost his life, but his servant Matsukaze carried on his work. Wanting to warn future generations, Matsukaze got himself petrified.[4][5]

In the year 5736, the Petrification Weapon was used by Kirisame and Moz against Amaryllis and her four friends to prevent them from fleeing the Island. Amaryllis managed to survive but with a grudge against her oppressors. Having learned the truth that the petrification was caused by a physical weapon, led her to concoct a plan to liberate the people of the island from its threat.[6]


Environment and Artifacts[]

After the fall of civilization, the vast majority of human creations succumbed to deterioration and were erased from the world. Some places such as Japan were overtaken by greenery, though climate changes brought by the disappearance of humans and thousands of years have also altered the landscape in other ways, for example, the whole world got colder, making snowy winters in Japan a common occurrence. The west of the Andes range in South America became more dry, and thus the Atacama desert, which formerly occupied the general area of south Peru, Bolivia and northern Chile has extended all the way to Ecuador. Due to geological processes, the land has also been greatly distorted. The topography of Japan is not very recognizable due to volcanic activity, and Treasure Island got larger due to volcanic eruptions.

When a surveying satellite was launched by the Kingdom of science, many other new features of the world were found in addition to the known ones. Large areas were flooded and became part of the ocean, most noticeably in the south of Africa and north of Brazil. The eruptions of volcanoes at Yellowstone reshaped large areas of north America. Australia gained more land to the north east by the sheer proliferation of coral reefs. The plains of China became wetlands with massive rivers, and the desert regions of Africa also became more humid, getting covered by forest and savannah. Although it wasn't the object of any observation by the characters, a land passage along the Bering strait seems to also have formed.

Traces of the civilization that existed before are few and far between but existing none the less. The Great Buddha of Kamakura was the first artifact uncovered in the series, and a large one at that. Its composition of mostly copper protected it from corrosion and also prevented vegetation from taking over its surroundings. Remains of concrete buildings such as Roppongi Hills Mori Tower are occasionally well preserved enough to be inhabited by people. Collapsed buildings can also be seen under water off the coast of North America.

The Soyuz capsule in which half of the astronauts made landfall at Treasure Island also survived though greatly deteriorated. Inside it was filled with concrete, encasing some glass bottles containing the salvaged rare metals from the Soyuz capsule itself, and most importantly, the tiny grains of gold and platinum collected by Byakuya during the rest of his lifetime. Likewise, what was believed to be a headstone belonging to Byakuya's grave, which was brought over to japan and sat at the Ishigami Village cemetery, turned out to be another concrete time capsule containing a glass record wrapped in aluminum foil, with the voices of the astronauts and music by Lillian Weinberg.

In America, a platinum ring survived the entire time inside the statue of Carlos Barrios, who spat it out once depetrified, and was used as the catalyst in a Haber-Bosch plant at the American Colony.

The Suez canal also inexplicably survived, being only blocked by a narrow dam-like structure made of old dead trees, which is believed to have formed naturally and was blown up with a cruise missile to reestablish the passage.

Another notorious inexplicable artifact is the headband worn by Yuzuriha at the time of petrification. When Taiju came across her statue at the camphor tree, she was still wearing it in the same position, which assuming it was made of plastic, steel, cloth or a combination of those, would make it virtually impossible for it to survive more than even a few decades out in the open. However, since Senku got to her location long before Taiju did, it's possible, although unlikely, that he crafted a replacement headband to make her more recognizable and stand out among the foliage.

Foundation of the Kingdom of Science[]

Village Games Arc & Village Origins Arc[]

After depetrifying, Senku Ishigami discovered the world as he knew had changed. Having kept count of his time petrified, Senku estimated roughly 3700 years have passed and he was in the year 5739. Marking the year on a tree, Senku decided to find a way to survive.

In a matter of months, Senku recreated a lab, clothing, and the antidote to the Petrification. On October 5, 5738, he revived his childhood friend Taiju Oki and they worked together for a while.[7] Soon they revive another childhood friend Yuzuriha Ogawa but a problem arose with the revival of Tsukasa Shishio. Tsukasa sought to revive the young and strong rather than the old and greedy.

Tsukasa attempted to bargain with Senku on giving up Science but Senku refused. Seeing this, Tsukasa requested the revival formula and seemingly killed Senku.

However in truth, Senku was not dead and faked his death. He had his friends return to Tsukasa to act as spies for him.

Subsequently, he found a village were primitive humans were living. After much time living among them, he found himself the chief of the village. He also discovered that the village was founded by his father Byakuya Ishigami and his astronaut team (who survived petrification) with the humans there as their descendants.

Stone Wars[]

Vs. Hyoga Arc & Communications Arc[]

Realizing Senku might be alive, Tsukasa started to revive more people, leading to the creation of the Tsukasa Empire or Empire of Might.

Tsukasa sent the mentalist Gen Asagiri a spy to infiltrate Ishigami Village but the latter defected to the Kingdom of Science.

The first battle soon to place between the Empires occurred after Tsukasa sent his top Lieutenant Hyoga to wipeout the village. However, Hyoga was forced to retreat because of the Kingdom's developing weapons to combat them but not before having the village burned down by his right-hand. Hyoga reported to Tsukasa of Senku's survival, this officially set the path of war in motion.

A few months later, the Tsukasa Empire lost to the Kingdom of Science upon Senku's invention of dynamite as a method of forcing a stalemate. Subsequently, the empire's dissolution followed after Tsukasa's defeat and Hyoga's capture, and the faction merged with the Kingdom of Science.

Stone World Voyage[]

Age of Exploration Arc, Treasure Island Arc, New America City Arc[]

Sometime after the war, the Kingdom of Science decided that they must gather a way to secure more ingredients to create unlimited revival formula. They decided to travel the world and revive everyone petrified. They revive an experienced sailor and his associate to build the most amazing ship to travel the world.

During this test run, they created the motorboat and hear the transmission of a person asking “why”.The sign that there are other humans out there.

Working together, the Kingdom got to work and made more advancements to the Stone World: such as the recreation of clothing stores, GPS, metal detectors, and paved roads. They also brought back traditions like Valentine’s Day after several months completed their ship. In the year 5741, the Perseus was constructed and they set sail for Treasure Island, the island where the astronauts originally landed on Earth.

While on the Island, they discover that there exists another civilization of primitive humans called the Petrification Kingdom who were under the thumb of a tyrant named Ibara who secretly ruled from the shadows. It also turns out that one of the Kingdom Science's villager Soyuz came from the Island and told them of a weapon that petrified people. Indeed, Ibara used the Petrification weapon to silence anyone, including the original leader.

Ibara had lackeys petrify most of the Perseus' crew and engaged Senku after his crimes were exposed. However, Senku outwitted the old leader and petrified Ibara. The Petrification Kingdom was liberated coming under the possession of the leader's son Soyuz while allying with the Kingdom of Science.

Matsukaze is also released, being able to carry out his mission by telling them the history of the weapons. He subsequently joined the kingdom, as a new Warrior.[4]

The Kingdom of Science gathered a new weapon and learned of an ominous threat called the Why-man, who had previously been enigmatic to them before. They learn Why-man is on the moon, deciding to travel the world and gather materials for space travel.[8]

The Perseus sails for America after they successfully save Tsukasa and gather more warriors to join the cause.[9][5]

Soon they arrive in San Francisco, where the once great city is shown to be in the same state as the world. The crew travel the area and hunt attacking wildlife to restock up on supplies.[10][11] Soon they discover corn before they come under attack by a unseen revived human who has recreated guns and cigarettes.[12]

The unknown attacker is revealed to have re-create an aircraft. Despite heavy attacks, the aircraft is brought down by the Kingdom of Science to proceed to salvage the downed plane. It is also revealed that there are even more Americans who were revived as the attacker is in contact with others who is skilled in Science like Senku.[13] The American Colony inhabit a large fortress, which was created by the scientist Dr. Xeno.[14] Xeno's colony consists of a former military soldier Stanley Snyder, the same attacker on the Kingdom of Science and few dozen others.[14] However, despite the capabilities of Stanley and others, their numbers are lacking because they do not know of the Revival Fluid.[15][16]

Much later, the groups both send one of their own to infiltrate the other. This results in Senku nearly being sniped, while Chrome organizes a successful attack in which Xeno is captured.[17][18][19]

Senku and his group commandeered one of the American ships in the escape. Knowing that the enemy has their ship, Senku uses a trump card. He negotiated with Dr. Brody for a truce and offers the ingredients for the revival formula and his plans to free over a million people. By doing this he hopes to create the first city in the Stone World.[19]

Brody contacts the crew of the Perseus and after a tense talk, the alliance formed but Brody was (correctly) aware Stanley would most likely hunt Senku and his group.

South America Arc[]

Senku and his group set sail for South America where they hoped to find the cause of the first petrification that occurred thousands of years ago. It was also shown that Xeno was aware of the Why-man and his presence on the moon.[20]

After a long trek to the Amazon rainforest, the science group discover a pyramid made out of the petrification weapons which are completely drain of powers.[21]

The Science group later contact their allies in America to activate the Petrification Weapon after they recently recharged it. Despite the many casualties from the American forces, they were able to reach the device and petrify the entire world once more.[22][23]

New Stone World Arc[]

Three years later, Suika is revived, making her the only known human in the world. Suika uses her survival instincts to fend for herself until she can find a way to revive her friends.[24]

Suika collects her petrified allies, while continuing to fend for herself. Soon enough, she finds a paper holding instructions for the Revival Fluid and starts gathering supplies. She ultimately succeeds and Senku is revived.[25]

Senku effortlessly creates more fluid and the Science group is revived.[26][27]

With establishing of Superalloy City, as well as the revival of several people, the population expanded.[2]

Globetrotting Arc[]

After leaving South America and traveling across the Atlantic, the Kingdom of Science begin the world voyage to revive all of humanity. During the way, they revive a message from Why-man asking "DO YOU WANNA DIE?". Believing this to be a threat, and that they may be working on borrowed time now, the crew head to Barcelona in Spain to craft three items necessary for the space mission from the mineral, fluorite.[28]

On the way to Barcelona, the Kingdom of Science harvest and crush olives into liquid form and run it through a centrifuge, which Kaseki builds in a matter of seconds. Upon obtaining olive oil, Francois is moved almost to tears at the thought of how much the olive oil will improve the meals they create, and go onto create two dishe's for the Kingdom of Science, much to their enjoyment. Later, the Kingdom of Science revive the local petrified residents of Barcelona. Francois prepares an opening banquet for them and even shows off a little Spanish they were taught in South America.

Later, Kohaku and Chrome head out in order to discover food sources, and run into a wild pack of bulls. Chrome begins to get chased by one of the wild bulls, with Kohaku stating he's being used as bait. Ryusui jumps at the opportunity and begins to bullfight, amazing most. Francois and local chefs later prepares churros, a sweet Spain is known to create, and Ryusui pays said chefs with coin dragos, which they created from the ores in South America. The locals are amazed that in the stone world even with the scientific head start, they aren't trying to rule over them but rather intend to bring back the old world. The locals kneel down to the Kingdom of Science to thank them, but Ryusui has them stand, and rallies the locals up to work in exchange for compensation. With the locals agreeing to begin work, Ryusui exclaims his desire for fluorite.[29]

After obtaining fluorite in Barcelona, the crew made use of it's low reflecting index to create better a telescope. To do the calculations for the space rocket, Ryusui says they'll be going to India and founding Math City. The problem is the new Perseus goes through fuel faster than expected, so going the full route around the Cape of Good Hope will mean waiting for months before they can safely make the journey. Chrome suggests they make their way through the Suez Canal, however there's a risk it's blocked and they'll be left stranded. To avoid the risk of not being able to turn around in the canal, they use their new telescope and a hot air balloon to scan the route.

Chelsea makes a map of the area, only to discover there's a small dam 20 km into the canal, blocking the way. Senku decides that it would be a great opportunity to test a ballistic missile from adding dynamite to a model rocket, it's fired directly into the dam to blow a path through it.[30]



  • While never addressed explicitly, the damage from global warming would have had 37 centuries to heal.
    • Chelsea later explains that with all the humans petrified and thus unable to pollute, this resulted in global cooling.[31]
    • It also caused drastic changes to weather and landscapes, making any modern memorized biome maps inaccurate.
    • Any dangerous radiation from nuclear waste will have dissipated, as it takes between 1,000 to 10,000 years for it to return to the radioactivity of the original ore.
  • While never noted in-series, all post-petrification humans speak Japanese. None of the Japanese pre-petrification humans have had trouble talking with them, meaning that it was the only language in the world for a while.
  • By the end of the series, humanity has returned to the level of technological progress it had in the 20th century when everyone was petrified.
