Noah is an antisocial high school student, but behind his unassuming appearance lies an extraordinary secret. Online, he is an enormously popular strategy-game streamer, and in the real world he operates anonymously as “ARK,” a masked military strategist whose remote commands can determine the outcome of actual wars. His strategic genius becomes so influential that a major world power decides he is simply too dangerous to remain alive. Noah is assassinated, but instead of dying for good, he awakens in another world teetering on the brink of extinction. Humanity is being overwhelmed by relentless attacks from monsters, and the few remaining survivors possess nowhere near enough strength to fight them head-on. But raw power isn't what Noah specializes in. Taking command of a Queen, magical warriors, and a desperately small fighting force, Noah begins turning hopeless battles around through strategy, coordination, and his unparalleled ability to predict the battlefield. The greatest commander in human history has been given an entirely new battlefield, and this time, the survival of another world rests on his tactics.
