As the Supreme Commander who successfully united the continent after a grueling Great War, he thought his greatest battles were over. However, humanity’s hard-earned peace is shattered instantly by a sudden, devastating demonic invasion. Betrayed, cornered, and facing the total destruction of civilization by the very forces he failed to anticipate, he breathes his last—only to wake up with a second chance at life. Armed with the memories of his past failure and the impending apocalypse, he must now rewrite history. This time, instead of eliminating those destined to be heroes, he has to forge a path to survival and protect humanity from complete annihilation.
