20X1 year

　July 15.
　All humanity receives an email from the [World Salvation Project].
　The above email was thought to be a massive junk mail, but at 17:00, things changed rapidly. A threatening email arrives to the heads of state with the following message: 'Please issue a recommendation to the heads of states to have their citizens undergo a suitability study; if the promise is not fulfilled by 18:00, the defense minister's life will be lost; if it is not fulfilled by 21:00, the prime minister's life will be lost.' The defense ministers of countries (including our country) who ignored the instructions in the email died one after another at 18:00. Countries advised their citizens to undergo a suitability investigation. This day was later called 'The Great Change'.

　16 July.
　Impenetrable zones appear in many parts of the world.
　The more densely populated an area is, the more inviolable it is. In the capital city of Tokyo, more than 90% of its land has been invaded by inviolable zones.

　July 17.
　He decides that it is impossible to conduct politics in Tokyo. The functions of the capital are moved to the "Mega-Float," a self-sustaining city of one million people built on reclaimed land in Tokyo Bay. A total of 800,000 people, including government officials, academics, and celebrities, move to the city. The remaining residents of Tokyo migrate to neighboring prefectures such as Chiba, Ibaraki, Saitama, and Gunma, partly because the transportation system has been destroyed.

　July 25.
　A country drops a nuclear bomb on an impenetrable zone. The result is that the inviolable zone is unharmed. The only thing that happened was that more land became uninhabitable for human beings.

　August 16.
　10:00 a.m. A revelation comes to all of humanity from the tentative goddess. It turns out that the inviolable zone is called the dominant area. The revelation was so one-sided that we couldn't ask any questions.
　After receiving an aptitude survey, human beings (called Lowe from now on) installed the application of "World Salvation Project", a gift from the goddess, on their smart phones. From then on, it was possible to invade the territory they controlled.
　Some humans are now able to induce magical paranormal phenomena called special abilities.
　An investigation by the SDF reveals that only 12 people can enter the controlled territory.
　At 6:00 p.m., the hawkish SDF officials run amok and dispatch a total of 12,000 SDF personnel to their controlled territory across the country. The results are disastrous, with 3,876 deaths, and several high-ranking hawkish SDF officials take responsibility and resign.
　It was discovered that a strange creature - a demon - inhabited the territory under their control. The demons are found to have "science as the fruit of wisdom" - that is, modern weapons, including guns, are found to be ineffective.

　August 19.
　The first Japanese person to level up is born. It's hard to believe, but defeating a demon raises its level and allocates BP to its body, which increases its physical abilities. We have also confirmed the existence of a treasure chest inside the dominion area. Some of them contained weapons and armor that were effective in fighting demons.
　From this day on, more and more humans begin to invade the Dominion Realm in search of riches and honor.

　August 23.
　A week has passed since the "Revelation of the Goddess".
　Fortunately, our country's people did not die of starvation due to the processing of food by biotechnology, but in some backward countries, people died of starvation one after another, and there were countries that ate the demons that lived in the territory they controlled. However, some food and drink that was common before The Great Transformation has become a luxury item.

　August 27.
　Sightings of demons forming a party outside of the controlled territories arrive in Yokohama. Many humans who thought they were safe outside of the controlled territories die.
　After this incident, the number of humans who invade (level up) into the Realm of Control increases. According to statistics, nearly 70% of humans (Lowe) now travel to the controlled realm.
　In addition, local governments and influential companies began to support (enclose) the talented humans (Rowe). Naturally, the Japanese government, to which I belong, also supported the excellent human beings (Rowe) active in Tokyo.

　September 14.
　The United States becomes the first country in the world to successfully liberate its territory of control. Two hours later, Germany also succeeded in liberating its territory. From this day on, the good news of the liberation of the controlled territories began to circulate around the world.

　September 15.
　He succeeded in liberating the territory he controlled in Japan. The first success was achieved by SDF personnel in Hokkaido. After that, the good news of the liberation of the dominion territory came one after another in Kanagawa, Fukuoka, Osaka, Kobe, Aichi and Miyagi.
　By this time, a lot of information about the inside of the dominion territory had been accumulated, including the types of monsters living in the area, the types of traps set, and the existence of rest stops.

　September 18.
　A human being (Lowe), supported by the government that has liberated the territory it controls, tells him the surprising information that the Demon King may be a former human. The Demon King is a former human...?　The number of Demon Lords in Japan is about 16,000, and if 16,000 Demon Lords are ex-humans..........doesn't anyone in their family notice?　It seems to me that at least one of them could be reported. But I've never heard of such a report. Then it's a foreigner?　However, there are reports that the Demon King looks very similar to the Japanese. From the future?　Are you from the parallel universe?　Extraterrestrial...?　If it was the Kowaleta world like it is now.......it's not an impossible theory. The mystery of the Demon King's ecology has only deepened. Is it possible for a supporting human being (Rowe) to negotiate with the Demon King?　I asked him if he would be able to do it, but the answer was "not possible".

　Nov. 1.
　A government-led project that will determine the future of humanity - "Operation Demon King Capture" has begun.

　November 7th.
　The fact that the Demon King cannot be taken out of the controlled realm is discovered. The project is reviewed and changed to neutralizing the Demon King inside the dominion realm.

　November 19.
　He fails to neutralize the Demon King, but gains important information.
　It seems that the Demon King is using his smartphone to create demons. In other words, taking the smartphone away from the Demon King is the key to the future success of the project.
　Creating a demon with a smartphone?　Is the Demon King's ex-human theory correct?

　December 3.
　He succeeded in neutralizing the Demon King.
　Since we're not allowed to write the name of the disabling demon king, we'll call him A.
　We were able to get various information from the neutralized Demon King A.
　(1) The Demon King is a former human being. The reason why we don't have personal information about the Demon King when we were human beings is because all of his existence (memories) have been erased.
　(2) The concept of level exists for the Demon King as well as human beings (Rowe). The depth of the hierarchy corresponds to the level of the Demon King. The level of the Demon King A was 2.
　Although he was level 2, the ability of Demon King A was comparable to that of the human beings (Rowe) who were level 15 or above.
　(4) The demons created by Demon King A could not go outside of his dominion area.
　(5) The Demon King tried to analyze the smartphone in his possession, but he was unable to unlock it by any means.
　(6) The Demon King has access to the Internet.

　The last case (6) was controversial. There were frequent posts on the Internet from people who claimed to be the Demon King. Although not all of the posts were said to be written by the Demon King, some of them were thought to be really written by the Demon King.
　In response to this fact, some of them chanted that the communication lines should be cut off. However, it's impossible to pinpoint and shut down only the Demon King. There are currently seven base stations in Japan, and the range covered by a single base station is so vast that if they were to be closed, the people living in the area would not be able to connect to the Internet.　In the modern era, the Internet has become an integral part of our lives. It was impossible to live a life without the Internet.
　Even if we tried to identify the IP address of the Demon King, the existence of the Demon King had been erased from our memories and records. Although the logic was unclear, we could not find the IP of Demon King A's smartphone even if we contacted the relevant carrier or provider. However, it is available. Do traces of the Demon King exist just because we can't recognize them?　It was a specification that seemed in bad taste to be an act of God.
　There was a proposal to shut down some of the widely publicized sites, but there was an outcry from the public... Above all, human beings (Lowe) who are working hard every day to liberate their domain of dominance have a habit of exchanging information on the Internet.

　In the end, the outcome of the discussion - the opinions of the humans (Rowe) who are working hard to liberate their territory day in and day out - are respected and the status quo is maintained.
