In a world where magic is everything and the sky is shielded by a barrier maintained by the "Magia Vander," Will Serfort is an anomaly: he cannot cast even the simplest spell. Despite this, he attends the prestigious Regarden Magical Academy, earning credits by hunting dangerous monsters in the dungeon using nothing but his sword and immense physical talent. Driven by a childhood promise to his friend Elfaria—who has already ascended to the rank of Magia Vander—Will must prove that a blade can reach the heights of the tower just as well as any wand. As he climbs, he uncovers the dark truth behind the "Terminalia" and the invaders from the sky that once nearly destroyed the world.
