This is a game played by the gods. With a casual roll of the dice, they decided the fate of the competition between the demon race and all the other races.
The Demon King and the Hero were destined by the gods to be eternal enemies. The Demon King would be granted absolute power, while the Hero would have to gather the strength and hopes of every race to challenge him. The winning side would then receive from the gods the chance to have any wish granted.
But after all the races had given everything they had to raise a Hero capable of defeating the Demon King, they discovered that the gods' game had no end.
The Demon King would keep appearing, and the races would have to spend their resources again and again to raise parties of Heroes, trapped in an endless cycle.
At last, the races grew weary of the gods' game. The once-revered position of Hero became an empty seat no one wanted, until a hundred years later, when a simple country boy inherited the title. He took his childhood sweetheart to the church to ask the gods for a divine companion, and received an abnormal angel.
"What's abnormal about me?!"
Hearing this, a certain white-haired angel, who was nursing a baby, complained indignantly to her husband.
