The final war “Titanomachia”. After a deadly battle, humanity completely destroyed the demons and won. Twenty-five years later. Alan, one of the Seven Heroes who subjugated Demon King Beelzebub in the Great War, is already 43 years old. As a frontier knight commander, his superiors and subordinates said things like “Rotor” and “the heyday has passed”, but he lived a peaceful life. However, things take a turn for the worse. The demon army, which should have perished, suddenly revived and attacked. Subordinates who are defeated without resistance. Aristocrats who just push responsibility to each other. So Alan stood up again. This time, to cut off the root of evil and connect it to the next generation. In response, the former comrades-in-arms gather again. Now, seven legends return to the battlefield! !
