In a universe where new life is harvested for mana, Earth's unique scientific prowess is its only advantage against a magic-dominated galaxy. The ancient Tellask Empire, which mastered magic millennia before humanity even discovered fire, has Earth in its crosshairs. Aliens, upon discovering magic, halted technological progress. Earth's advanced technology is powerful, but its true hope lies in integrating alien magic into its weaponry, using the enemy’s own tools against them.
Daniel Thrush, the sole human capable of learning magic, is Earth's crucial asset. As the government relentlessly pursues transforming monster-harvested mana into standard-issue weapons, Daniel must embark on a perilous journey. Despite his profound reservations and the weight of an entire world on his shoulders, he leaves Earth to bring back the magic necessary for humanity's future.
