Demon Kings

The most powerful individual in the Demon World. The Demon King is not the ruler of the Demon World, rather he is the protector.

History
Around 500 years ago, the Demon King Palace ended the Era of Struggle and unified the kingdom.

In the Human World, 500 years was a long time, and they spanned dozens of generations. However, it was different in the Demon world. Like the other species of the Demon World, the demon kings had longevity, so there had only been six demon kings who ruled during the 500 years of history.

The invincible king, who ended the Era of Struggle, had ruled for the shortest period of time. He had established the Demon King’s Palace and left his position in the 12th year of his reign. The first demon king was an old man by the time he set up the palace. It had taken him over 100 years to end the Era of Struggle, so he had led his army for over 100 years. The demon king was obviously old, but the decisive reason for his retirement wasn’t age. When considering the lifespan of the Sura, the demon king was only middle-aged when he retired and still far from death. There was only one reason for the first demon king to step down. He had become weaker. The demon king of the second generation had surpassed his strength.

The second demon king had been the first demon king’s nephew. The first demon king had no children, so it seemed natural for his nephew to rise to his throne. For several species in the Demon World, it was natural for family members to succeed the throne. However, the real reason why the second demon king inherited the throne wasn’t because he was the flesh and blood of the first demon king. It was for a much simpler and clearer reason. By the time the first demon king stepped down, the second demon king had become the strongest person in the Demon World.

The second demon king had reigned over the Demon World for over 100 years. The third demon king after him had been the strongest among his children. The third king had also ruled for a long time. In the fourth generation, the one who had inherited the title of demon king was his much beloved third daughter. However, she hadn’t been the strongest person in the Demon World, as all her predecessors had been. She hadn’t even been the strongest among the children of the demon king. She had been able to rise to the throne because the third demon king loved her very much. However, her siblings had then fought and killed each other.

The one who had ended up becoming the fourth demon king had been the strongest of the remaining siblings, both individually and with the forces behind him.

The fifth demon king had been the eldest son of the fourth king. He had been the strongest among the children of the demon king but not the strongest person in the Demon World. He then became obsessed with the bloodline of the ancient king and made a law that only the children of the queens could inherit the throne among the children of the demon king. The fifth demon king had many concubines, but his queen had been a Sura who was his cousin and had been with him since childhood. In the fifth generation, the king and queen only had one child. Therefore, the sixth demon king had been able to rise to the position without any competition.

However, ironically, the sixth demon king was the strongest person in the Demon World, unlike some of his predecessors. He was the Sura King, Mitra.
