The story begins in the capital, the demon kingdom Asgard, the castle of demons Delsgido. Sitting on the throne was the demon king Arnos Salvador, who achieved peace with humans after a long war that lasted thousands of years. The demon king achieved his goal, which was peace. The goal of the demon king Arnos Salvador was not war, but he was a lover of peace. Anos was a strong, brave and kind king who mastered all types of magic, from demonic magic to divine magic. Arnos was strong and did not know the meaning of fear, regret or even surrender. He did not lose even once in his life for a million years. He fought wars that he did not want to fight, but humans had a firm belief that with the death of the demon king, peace would prevail. So Arnos decided to make a deal with the hero of humans. The deal was to establish a barrier between the world of demons and humans, heaven, gods and spirits, separating all creatures and keeping them in their own world, the land of demons in the land of demons and humans in the land of humans. On that day, Arnos was very happy, so after celebrating with his soldiers for a while, he returned to his room. He opened the door of his room and headed towards his bed and He threw it at him and opened the drawer next to his bed and took out a novel he had been reading for a while. He found it in his office and liked its title. The title of the novel was The World of Destruction. Arnos reached the end of the book. Luckily, he found a complete series of this novel in the Satanic Library. Today, he would read the end of the novel. He was happy and sad at the same time because the novel was the only thing that separated him from the outside world. So, he started reading, listening to the events of the story. Then, while he wanted to read the book, Anos felt sleepy and decided to sleep because he was probably tired from the celebration and took it as an excuse to postpone reading the novel. He closed his eyes and fell into a deep sleep.
