Onward the domain of mankind, the sky overshone by the sparkles brighter than the constellations and stars. Those sparkles, were no mere stars, they are scattered fragments emanated from the eidolon of the lost, ruined realms beyond human's comprehension...
Nobody knows nor understands it, but it happened.
The world trembled violently to the unknown collision that is taking place all over the cosmic sky.
As the remnants the phantom worlds faded, the very globe seemed to quiver greately, and, the fabrics of reality began to shatter like pieces of glass.
On the other side of these heavenly craters, thousand of foreign lands unknown to mankind deliberately emerged. They were just like us, the confusion and fear were etched on their faces. They clearly weren't the culprit of this multiversal occurence, but the victims of it.
At first, many misunderstoods occurred, and many bloodshed wars had happened almost everywhere. However, after 127 years of endless meaningless wars, many factors from each worlds had decided to form a unity and gained temporal peace. As the size of globe had extended to the approximate size of a galaxy, lack of accomodation wasn't a problem. However, there were still many wars arising in several distant lands that had yet to form alliance. With a view to solve the current situation, various organisations were founded to protect the innocent as well as put an end to the meaningless wars. One of these organisations is the Magia Unison Cooporation (MUC), a foundation that consists of special magical girl forces that not only save the lives of innocence but also ending meaningless wars by either propose an alliance or to defeat the tyranny.
There are different theories around the strange collision that took place over 200 years prior. Many scientists theorizes that the collision happened as a result of an unknown disruption on quantuum scales that eliminated the boundaries between different alternate dimensions. It is generally believed that in quantuum physics, all possible outcomes had already been happening or will be happening in a seperated world. It is an well-known hypothesis regarding the Many-World Interpretation. These worlds were beyond reach, as there's a boundaries that prevent us from reaching other universes, for a reason.
However, many also give credence to a higher-dimensional being and their greater scheme. People believed that the Merger happened because of a decision, a plan of a powerful, ethereal deity beyond mankind comprehension, the apex of all existence.
Nonetheless, it is all a matter of opinion and perspective, since none of the theories have any actual reliable evidence nor sufficient proof. The Merger, remained an unsolved mystery.
But, that doesn't stop mankind, and perhaps other humanoid creatures from other worlds from exploring and trying to understand the truth behind the Merger. For that reason, Year 130 AM (After-Merger), the Society of Wisdom was founded by Albert Einstein II[1], the genius among geniuses and the inventor of Relativity Theory, as well as other quantum-related theories.
Somewhere beyond—
There lies a realm, beyond mankind's reach, beyond the hands of divinity.
A woman in the white robe, who observed everything that happened and is happening in the story.
The suffering of these unawared characters weightened her heart, as she realized mankind was destined to lose against the corrupted divinity. It is a fixed rule, a fundamental law to every existence, that they cannot defy the Divinity. The gazes of the divine run life down, giving an impression that they treated it as a comedy show.
It irritated her.
As she who dwells externally, cannot directly intervene the Realms. Just like an author cannot get inside their own stories. Nonetheless, she can create a "character", a Deus ex machina that could solve the equations, an unexpected factor that breaks the chains of fate and narrative.
That factor was known by the name—
[1] Albert Einstein from another universe, I assume. You can also say this is Baddie Einstein considering she's a genderbent version of Einstein.
