On a mystical continent of the ancient world, there exists the human realm... and the demon realm.
Both realms sought to plunder resources and territories, igniting a war between the two that lasted for hundreds of years.

The demon's troops from the barren zone passed through the border and initiated an attack against the wealthy human world, while the humans formed an army comprised of diverse warriors to defend against the demon troops. Even though the humans, elves, and dwarves have nothing in common, they chose to work together to protect their land. They attacked the demon troops over and over again, without knowing how long the resistance could last...

The demons from different regions worship their own leaders──Caesar, Baal, Satan, and Iblis. Because of this, the demon realm is divided into 4 factions. They've never united in the war, lack discipline, and are completely without strategy. The only reason they have not been annihilated is due to the speed at which they breed.
Since ancient times, neither side dominated the war, causing it to continue for centuries. The war grew more intense as the years dragged on.
The Archdemon Caesar, is the only male among the leaders of the demon realm. However, he never cared about the territory or his family's property. He immersed himself in debauchery and wasted his life. Although he possesses powerful strength, he never wanted to use it in battle, let alone some ridiculous desire to conquer the world. His degenerate and ridiculous behavior caused his troops to revolt against him. All the insurgents were crushed by Caesar's unstoppable force. Then, one day, the unruly Caesar came to a realization.
"If I conquer the world, that would mean... all the women would be mine."
Humans, elves, dwarves, princesses, knights, generals, or even angels and other Archdemons...
So, the king of demons, Caesar, left his throne.
Three other Archdemons exist in this realm... while in the human realm there's the leader of the templar who knows no fear, the chief priest that holds strong to faith; a herculean dwarf king, the princess of the largest empire known to man, an exorcist with the blood of a fox demon, the undefeatable swordsman from the ghost tribe, and the secluded elf queen...
As for the women... there's Caesar's sworn enemy, a woman that fluid bonds with him, his friendly acquaintance, and... the woman who recovered her future only after their fateful encounter.
The story of Caesar's ambition... starts here.
