Beneath the Hellish sky, shrouded in sulfurous fog and adorned with comets of fire, the vast Abyssal Kingdom stretched out. Here, millions of demons and creatures of darkness roamed the land and soared through the air, forming countless legions. This palace of power was ruled by King Satan, the Dark Sovereign, the Supreme Demon whose power could manipulate dimensions. And at the heart of his dominion, was the heir.
His name was Rein Elmys.
At the tender age of seven, Rein was a highly unusual figure. He possessed the fiery red eyes inherited from his father and perpetual messy, jet-black hair. However, it wasn't his demonic blood that made him unique, but the chronic boredom he suffered from.
To Rein, Hell was just a tedious playground. The power that flowed within him—the power to summon abyssal storms, convert matter into pure energy, or simply make things explode—was only ever used for the most trivial of purposes: mischief.
Rein once transformed the formidable Ancient General of the highest rank in Hell into a sparkling toad for three hours, simply because the General defeated him in chess. He also sabotaged the Grand Sacrifice Ritual by replacing the offerings with sweet jelly beans.
The culmination of his antics occurred that day, when he attempted to "redecorate" his father's throne.
With the void magic he had just learned, Rein tried to cloak the King's Throne in a cheerful purple color. Instead, he accidentally created a Temporal Void Hole. A small but terrifying rip in reality, which emitted an aura of nothingness and began sucking in light, matter, and even time around it.
King Satan's roar shook the very continents of Hell. "Rein Elmys! You almost destroyed the foundation of my existence! You do not grasp how precious the power you possess truly is!"
As punishment, King Satan decreed that his son must be banished.
In the Hellish Arena of Judgment, King Satan stood over Rein. Pure Hellish energy, the unmatched Black Chaos Magic, swirled around King Satan, hissing and igniting an energy storm. King Satan did not merely open a door; he demonstrated his absolute power by tearing reality itself.
With a cosmic scream, a giant dimensional rift split open in the air. It was a wound that radiated the cold light of a foreign world—the Human World.
"You will leave, without protection, without servants," King Satan's voice trembled with the power he wielded. "Your strength is sealed to its most basic level. You must survive, Rein. When you turn eight, the gate will open. If you fail to prove your worth, you will forfeit your status."
Accompanied by a faint sob and the worried gaze of demons, Rein Elmys, the seven-year-old Prince of Hell, was shoved into the swirling dimension, toward a world that did not value magic, a world he considered beneath him, the world where humans reside, namely Earth, where he must survive only with his cunning wit and the little residual demonic power he possessed.
The struggle of the mischievous little prince, punished to finally grow up, has just begun.
