[Machine Translation] I received a suspicious e-mail offering me "the right to reincarnate in an ideal world. If I could go to the game world where I used to play, I thought I would be reborn in... A game world that I knew nothing about! I made a mistake in typing a single letter, and ended up as a character in a game that I know not a single millimeter about. As I frantically search for clues, I realize that if I fail to conquer the game, the world will be destroyed by the Demon King... I have no choice but to predict the original story and complete all the events perfectly! The hero, who has turned into a "man who will definitely protect the original story", goes on a rampage in the miliary world...! A new kind of heroic tale is about to begin!
