In the 21st century, human civilization has almost been wiped out by genetic warfare.
Although the genetic engineering war did not cause any visible destruction or slaughter, it did inflict damage on humanity that was incomparable to World War II, and as a result, the world's population decreased to about 2%. Human civilization has returned to its primitive level.


However, in the 26th century, the global population began to recover. The recovery of the population reflects the desire of the Dragonewt to use humankind as a resource. It is known that the old mankind has been revived by the genetic manipulation technology left by mankind. In other words, in fact, most of the existing humans, not only the Daichi, are clones of ancient humans and their descendants. According to the Dragonewt, the history of the destruction and resurrection of humankind has been seen countless times since tens of millions of years ago.

Genetic warfare is different from conventional military and other wars that focus on physical destruction. Russia's genetic manipulation technology project that erodes, weakens, suppresses, and dominates other countries from the inside It is a global conflict between human beings that started with the "DINOSTONE Project".。

The whole picture of the DINOSTONE project is to first enter the industry and economy of the opposing country, Mainly through food, medical care, and welfare services, it begins by genetically manipulating the human race of hostile countries little by little and causing them to decline.


As a first step, first attenuate intelligence. And the desire to fight, the desire to work, the desire to leave descendants diminished, Furthermore, it spreads mental illness, lowers the national power of hostile countries, and causes the economy to decline. In the second stage, political intervention such as multinationalization from the acceptance of foreigners, The plan will be completed by putting the hostile country under effective control without destroying the hostile country or invading the country.

The DINOSTTONE project is all carried under the surface, and the invasion itself is carried out without the hostile country or other countries being aware of it. As long as the plan is not exposed, even after the invasion is seen as a natural economic outcome, Rather, it can take the position of a strong country that helped a declining country by prolonging its life. It was a project that should have been completed without receiving criticism from the United Nations for being unethical.

However, the defection of a certain scientist exposed this plan, With the outflow of genetic manipulation technology, conflicts began around the world between countries and between companies that blatantly used this technology instead of watering it down. After that, the credibility of all services such as food, medical care, welfare, etc. spread all over the world, even if they were domestic products. The notion of self-sufficiency, in which only one produces what one consumes, has become a social norm. The explosive development of human civilization brought about by the Industrial Revolution came to an end, and mankind returned to the age of hunting and farming.

A few generations after the "Dinostone Project", humans have already never used any machines such as cars, Many people shy away from it as an eerie foreign object left behind by old humans.

Japan was the first target of the "DINOSTONE Project". In addition to thinking that the Japanese national character was suitable for this plan, As a base for checking huge democratic countries such as the United States, and as a foothold for aggression against Asian countries, Japan was also considered important from a geographical point of view, and the "Dinostone Project" was implemented.

However, due to the global chaos caused by the outflow of genetic manipulation technology, the plan was abandoned halfway through. The revival of ancient creatures, which is the original use of genetic manipulation technology, begins.

The Japanese abandoned this land and scattered around the world, The Japanese archipelago has turned into a wasteland where giant ancient creatures roam. Although it is currently a restricted area, Daichi and the others have a facility where important secrets of genetic manipulation technology sleep. After hearing from a group of pirates that it was in this area, they decided to head for Japan.
