I thought I could find partners, defeat the devil, marry the princess, and reach the pinnacle of life just like in the legend of the brave man and the devil. During the battle with the Demon King's army, I witnessed the darkness in each kingdom, and came up with the idea of ​​re-establishing order after defeating the Demon King. But when I arrived at the Demon King's Castle during the magic live broadcast for the whole world, I saw all the top leaders of the Demon King's army kneeling down to me and shouting, "His Majesty the Demon King!" A sealed memory suddenly appeared in my mind. In this memory, I am the strongest world-destroying demon king in history, and even the gods of the starry sky were torn apart by me! At this moment, the strongest hero in history and the strongest demon king in history became the same person! This novel and its characters are purely fictitious.
