The “Great War of Heroes,“ in which the hero and the demon king vie for survival and power in each incarnation. The fourth great war was also a war where the heroes defeated the Demon King… it’s an undisclosed fact. Twoeight, the ace of the “Agency” in the dark side of kingdom, undertakes all the dirty work for country and supports the Hero to subjugation the Demon Lord from shadows. As the unsung hero, Twoeight hopes to live a peaceful life after the war. However, defeating the Demon Lord is not enough to bring peace to the world.
