Realms

Parallel Worlds are countless other worlds beyond entire other dimensions, referred to as the "Realms" which a world that exists outside the world where Cid Kagenō and the others live.

Overview
All these Realms of the countless worlds that exist revolve around a single point like a star system or galaxy, and the world where Cid lives is one of them. There are worlds of ice, worlds of poison, worlds of flame, an empty world without light and color, worlds where monsters live, etc., and the worlds other than the world where Cid lives are collectively called the Realms.

Because each world rotates at a different speed as the years go by, until the worlds sometimes collide with each other as the impact sends rifts across the worlds, which can affect each other's worlds with two different worlds become linked and each exerts influence on the other.

The reason why there are monsters and magic in the world where Cid and his friends live is because they collided with one of the demon worlds 10 million years ago, and monsters and magic power flowed in from the demon world. The concept of spirited away was born from the people of the world drifting away.

Cid's previous life, the real world, was no exception, as monsters and magical power flowed in due to the clash with the demon world, causing the collapse of Japan and Akane Nishino and others living in Japan to gain magical power due to the invasion of monsters.

History
The Cult of Diablos was conducting a geological survey of the world and discovered that 10 million years ago when the Dragon was once the ruler of the world before the realms began to collide, there was no magic in their world. The world then collided with a realm that possessed Magic which poured into the former, which had become a drastic effects on the world ecosystem. It was then that the Dragon went into decline because their race are unable to adapt magic and succeeded by humans which they become prospered where the dragons once thrived.

The Cult’s are working on their theory is that their world and the Realms are interact with each other on a cyclical basis and still exerts influence over each other, because they notice that the inhabitants from another Realm like the Magical Beasts are simply an animals from another world that evolved in response to magic and the beasts are operate on a fundamentally different logic, which defy every rule of nature. Considering this deduction, which means that the magical beasts might not be the only thing alien to their world. Because of this, there are still a lot of mysteries about of all the species in the world, even the cult's theory confirm that the humanity itself might not the original native on the world because Human are probably from a Realm.

Background
When the Cult of Diablos notice that the "Black Rose" are accidently open and also poured magical beasts at Oriana Kingdom during the siege of Velgalta Empire, which was a stroke of misfortune for both nation. The Cult of Diablos notice that the Black Rose" is a portal gate that can connect their world to Realms and decided to intervened by closed the gate and saved the Oriana Kingdom. With the cult stewardship of the "Black Rose" to ensured that the kingdom would survive in perpetuity, they decide to make a pact with the kingdom to give the cult a fair compensation, which is the Royal Blood and the majority of the kingdom's tax revenue will be given to the cult, resulting in the kingdom to heavily invest on the arts was so it could entertain them. Also, the cult are manipulating the church to persecuted Dark Knights as a way for the Cult to prevent Oriana from gaining the strength and no manpower to rebel against the cult, which basically became a puppet kingdom.
