The cause is that another timeline on Earth has collapsed and become frozen, and as a result, the souls that lived in that timeline are flowing into the continuing timeline.

If that is the case, the direct solution would be to increase the number of continuing timelines, but that is not so easy. In many cases, greedy people in the West have used nuclear bombs, destroying continents or Europe at best, and in the worst case, causing a shock strong enough to split the Earth. And then, the sky would darken, the Earth's rotation would gradually stop, gravity would become lighter, people would be thrown into the air, and eventually, they would lose consciousness due to suffocation (as the air becomes thinner), and that world would disappear. This has happened many times.

Normally, the population would not increase this much. Even if people have children, not that many would be born. Now, there are too many births. It seems that if there is no preparation and inflow of souls that want to be born, even if the body is fertilized, it will not grow beyond a certain point and will simply disappear.

Recently, there have been many attempts to control the world's population, and as part of that, there are attempts to reduce the number of Japanese people. If that is carried out, a world without Japanese people would lose its value, so this timeline would freeze, and a certain timeline would begin to move. In that world, a society would be restarted where Europe was destroyed in a world called the "Co-prosperity sphere" (Sphere of Co-prosperity).

There are opinions that the population should be controlled in various places, and some say that it is not necessary to control the population because the Bible says so. However, it seems that the reality is that some timelines are experiencing difficulties, and that is causing problems for other timelines.

Some people are born with the souls of animals because they cannot be born into the animal world, and the fact that the natural world is decreasing and it is difficult for animals and plants to live has also been a factor in including strange people in the human world. However, even so, people cannot be born unless their souls have reached a certain level of maturity, so this factor does not seem to be the main cause. Some people say that this is the cause of population growth, and while that is not entirely impossible, it seems that it has been happening to some extent for a long time. It is normal for animal souls to be born into humans when they have matured to a certain extent, but recently, it seems that it has increased somewhat because the animal world has become smaller. There are cases where animals cannot be born into the animal world, so they choose the human world, but even though there are a few more special cases, it is not a reason to explain the current population explosion in the world.

Basically, I am repeatedly reincarnating on this Earth, and although I am born on Earth, I have no other options, and this timeline is the only one available. As a result, the population of this timeline is increasing.

Choosing a timeline requires a certain level of spiritual maturity. However, if a timeline disappears, most people move together, so it's not something to worry too much about. But, if a timeline continues and you choose another one, a certain level of spiritual maturity is required.

In the future, the revival of timelines is foreseen or planned. I have mentioned this several times, but one is the revival of a world with a "Co-prosperity sphere" (a utopian society). It involves going back about 100 years, to a time before the modern era, and starting over. With the help of the Sirius forces, we will prevent wars in Europe. Another is a timeline that goes back about 500 years and restarts from the Sengoku period (Warring States period). If these two timelines are revived, the population problem of this timeline will likely be resolved. Suddenly, children will stop being born, and various speculations will arise about why. Some will say it's due to a virus or a conspiracy theory. Ultimately, if the number of souls choosing this era decreases, children will stop being born. It's a simple story.

The 100-year "Co-prosperity sphere" exists along the Pacific coast and offers free food. On the other hand, Europe and Africa, where slavery continues until the modern era, are in a hellish situation. It is foreseen that the Sirius forces will infiltrate Europe and improve the situation.

The other pattern, restarting 500 years, is a timeline where a certain kind of dictator carries out reforms for one generation, and then a democratic system is established to build a modern society.

These two timelines do not yet exist, but they are things that will happen in the future. However, since these types of timelines transcend time and space, for us who live in time and space, time is needed. But, after a certain period of time, someone will actually take the time to build these timelines in another timeline, and then we can transcend time and space and be reborn in those timelines.

Before reaching that point, if Japanese people are in a situation where they are exterminated like the Nazis in the past, we will quickly abandon this current timeline and revive a timeline that was once a relatively early attempt at the "Co-prosperity sphere" where Europe was destroyed. However, that is the worst-case scenario, and it is unlikely to happen.

In this vast universe where time and space intersect, construction and understanding are bound by time and space, but once created, they can transcend time and space.

Therefore, although it certainly takes time, the fact that these two timelines are planned and foreseen means that when they are realized, each individual will be able to move to the era after their realization, even if they do not wait the same amount of time.

Therefore, in terms of actual time progression, there is a certain possibility that you will be able to choose these timelines after this life ends. Even if not immediately after this life ends, you may see such a world being created and move to it in the process.

If that happens, what will happen to the current society? This world may also be saved. And, even if this world fails to be saved, it will simply be frozen and cease to exist. However, given the current trend, it seems to be heading towards being saved, so there is no need to worry too much about the destruction of this world.

If the entity governing this world desires the continuation of global war and chaos, then this world will be frozen, while the timeline where Europe was destroyed in the early stages of the Greater East Asia Co-Prosperity Sphere (which is frozen) will begin to move. If this world is ethnically cleansed and becomes a hell, then even if Europe was destroyed, that world would be better, and in the worst case, it would switch to that world. If overly greedy Europeans continue selfish wars and domination for their own benefit, then as a result, this world will be abandoned and switch to a world where Europe does not exist. If they are warned about this and still continue to be selfish, that will happen.

However, it is likely that such ruling classes will repent and reform, their souls will be saved, and this world will also be saved. If that happens, this world will continue to exist, and from there, two more timelines will appear.

Therefore, there will be three main worlds.

- The current world, which is likely to be saved.
- A world that goes back 100 years to the Greater East Asia Co-Prosperity Sphere and is saved (was saved) with the help of Sirius.
- A world that goes back 500 years and aims for a better Greater East Asia Co-Prosperity Sphere society.

There are also other smaller timelines, where the world has been destroyed since around the year 2000, and a small number of people have been rescued by spaceships and are living in colonies. In this timeline, there are quite a few greedy and hysterical people, with a strong sense of superiority, and a terrible situation has emerged, with spiritual and cult-like tendencies and a strong sense of superiority, resulting in a community similar to what you see in rural areas, with unintelligent people. Therefore, the god does not like this timeline either, but there are still a few people who want to create a new world in that timeline. However, this is not a choice that many people will make, so you don't need to worry about it too much.

There are three main timelines, and the creation or continuation of these timelines leads to a decrease in the world's population in this timeline.

The Kyōei-ken (a society based on cooperation and mutual benefit) has no food shortages, is peaceful, and while there are various problems, it is basically a society where the ideals are realized and people can live happily. If that is rescued by the Sirius forces, it would be good for many people to move there. Alternatively, creating an ideal Kyōei-ken would also be a good choice.

It seems that many people have tried to reduce the population, and the government has agreed to it to some extent, but in reality, even if the population is reduced in that way, if the number of choices of timelines is small, the population of this world will eventually increase.

Since the original cause is the lack of timelines, increasing the choices of timelines will lead to a solution to the problem.
