"The gods also have a hierarchy, but the lowest god isn't necessarily the weakest."
Shion Yorigami is the elder of the two lowly sisters, and the gods' ultimate weapon of last resort. The only way to stop a calamity is with another calamity.
You should come play with us in our garden sometime.
An unfavorable outcome is called unlucky. However, a single event can be lucky for some people while simultaneously being unlucky for others. Examples of this can be seen with bets or the rising and falling of stock prices. Your bad luck might be someone's good luck, and your good luck might be someone's bad luck. It's also the case that an unlucky incident one day can lead to a lucky break the next.
Deciding whether something is lucky or unlucky is purely subjective. It's the same as judging fate based on your own life. There might not even be a way to view the world objectively. Even if you used science, you could never be sure whether it's truly objective or not.
Shion has the most despicable bad luck and the most disastrous sorrow. If human luck and happiness are purely subjective, why does everyone tend to agree that when it rains, it pours, and that some people are less fortunate than others? It's because of the memory layer of the universe.
The physical results of good or bad luck occur in the physical layer, and they can be predicted with the laws of physics. Luck itself is of the mental layer, and each person thinks about it differently. Within these two layers, the same starting conditions will lead to the same results and the same thoughts. However, things can change in the memory layer due to the repetition of patterns. The universe's memory layer remembers what happened and when. If you're on a losing streak and are unable to pull off a remarkable comeback, you never will unless the universe remembers that you have made a comeback before.
Humans are inherently poor. That's why poverty gods are one of the most ancient types of gods. Even if there is a surplus of resources, someone will miss out due to how they are distributed. This gives rise to cheap labor forces that produce goods and provides services at low cost. However, the goods themselves are not necessarily cheap. Luxury items like gold, diamonds, chocolate, and coffee are distributed all over the world in crazy amounts, and despite their high market price, they are mined or harvested by poor, underpaid workers.
Felling forests for lumber and drilling for oil extract resources at an exponentially faster rate than they are produced, and they are used and consumed just as voraciously. While this does lead to immediate profit, it makes the environment poorer, leading to greater losses for the people of the future. Above-average wealth and happiness have to be taken from somewhere or someone. Human history has been built upon repeated instances of this, and as the years go by, it is happening on an ever-greater scale. What is humanity's end goal?
The worst calamity that could befall humanity is the extinction of the human race. For humans, this would essentially be the same as the end of the world. If you're wondering how humans will die out, the answer is through poverty.
Humans must escape to the stars before they use up all of Earth's resources. Already, there is not enough usable land for agriculture, which has led to increasingly dire food shortages. In terms of energy, fossil fuels are clearly not sustainable, yet an equally efficient alternative has yet to be found. There is also a limit to the amount of rare minerals that can be mined. Humans dream that these problems will be solved by expanding their domain to the Moon, asteroids, and other planets, until it eventually spans multiple star systems and galaxies. They have had this dream since they first started farming. But it is always shattered by the rampant poverty caused by unresolved global and economic issues that are always put on the back burner. As long as the next meal is deemed more important than launching rockets, there will be no future. This is the ultimate weapon of last resort, fashioned by the gods that the humans destroyed long ago.
