A long time ago, the demonic realm was a peaceful place. Demons worked together to achieve common goals, creating a utopian society where everyone was treated equally, regardless of their strength or power. For centuries, this system flourished. Leadership was not about might but character—the title of king was awarded to the kindest and most respected demon in the land, someone revered by all. This harmony made the demonic realm a unique and prosperous place.

But that all changed.

A thousand years ago, a demon named Satan appeared. Unlike others, Satan rejected the ideals of equality and cooperation. He believed the world should belong to the strong, and power should determine one's status within society. To Satan, those without strength were meant to serve those who had power. His radical ideals shocked every demon to their core, and thought many fought against him, many also followed him.

Satan's strength attracted followers—demons who called themselves the Spawn of Satan. They believed in his vision of a society built on power and domination. As Satan's abilities grew, so did the number of his followers.

Years of conflict followed as Satan waged a relentless war to conquer the realm. His forces crushed anyone who opposed him, and his influence became inescapable. Over time, the Spawn of Satan overthrew the rulers of every city and nation, spreading Satan's ideology across the entire realm. Finally, after a long and bloody campaign, Satan declared himself the first Demon King. On the day of his coronation, he announced the end of a peaceful society.

Satan proclaimed the beginning of a new era—one built on strength and ruled by fear. Power, not kindness or fairness, would decide everything. Weakness would no longer be tolerated, and those who could not prove their worth would be left behind. What was once a society of unity and equality was now one of hierarchy and oppression.

Satan's rise marked a turning point in the demonic realm's history. The peace of the past was gone, replaced by a brutal system where only the strongest survived. For the demons of this new age, power wasn't just important—it was everything.

Those who stood by Satan during the war were greatly rewarded. Satan granted them incredible powers and abilities, elevating them above ordinary demons. He appointed his loyal followers, the Spawn of Satan, as the new nobles of the realm, creating a powerful hierarchy. At the top of this new order were Satan's ten closest allies, who were given the prestigious title of commanders. These commanders were second only to Satan himself in strength and authority, making them some of the most feared beings in the realm.

Though Satan was a ruthless ruler, he believed in merit through strength. He introduced a brutal but fair system: anyone could rise in society by defeating someone of higher status. A common demon who dared to challenge a noble—and won—could claim their place among the elite. This rule created a world where ambition and power determined everything, and only the strong thrived.

Centuries have passed, but Satan's ideals still shape the demonic realm. The titles of king and commander have been claimed and lost countless times, but the foundation Satan built remains unshaken. His legacy of power and violence continues to define the realm, where survival and success depend on a demon's strength and determination.

To ensure Satan's ideals endured through generations, the nobles of the realm worked together with the current Demon King, Ravana, to create a prestigious academy. This institution would train young demons to embrace the values of strength and ambition that defined their society. The academy became a symbol of power, attracting demons from all over the realm who dreamed of rising in the hierarchy.

Admission to the academy was no easy feat. Only those who passed its grueling entrance exam were allowed to enroll. The test was designed to push candidates to their limits, ensuring that only the most capable and determined demons could attend. For those who succeeded, the academy offered a chance to hone their skills, develop their powers, and prepare for the battles that awaited them in the real world.

Here, students weren't just taught magic and combat—they were molded into warriors, leaders, and potential rulers. The academy became the ultimate proving ground for demons seeking to claim their place in a society built on power.
