A dragon manifested in a World—a world where humans, monsters, demons, and angels exist.
A chaotic World.
This World is divided into four dimensions.
The Dimension of Mortals, also called the Mortal World, contains only one composition: physicality.
The Dimension of Abominations has nothing physical. It is a realm of pure energy, where even time and space exist only as energy.
The Dimension of Devils, also known as Hell, contains only nothingness. Not even space-time exists there—only a Void.
The Dimension of Celestials, also called Heaven, is made of pure light. It is a conceptual world where both time and space are formed from light itself.
These four dimensions operate under completely different laws. The largest among them are the Dimensions of Devils and Celestials, both infinite in size, while the other two are each seven times larger than the universe.
Hell and Heaven are places where the duality between reality and fiction does not exist, transcended by the nature of these dimensions.
The dragon who manifested here is named Hikaru, the Chaotic Dragon. He manifested in the Small World, a world contained within the chaotic World and positioned at the center of the four dimensions.
This Small World is a place where demons, monsters, angels, and humans coexist.
Demons, monsters, and angels create avatars to interact with this Small World.
The Small World is a place where non-physical components can exist, making it a unique phenomenon.
Hikaru manifested here in human form—his hair shimmering like a night sky filled with countless stars. His clothes were pitch-black, and his skin carried an ethereal quality.
And thus began the Dragon's journey in this World.
