Synopsis: From Trash Job to World’s Strongest Swordsman

In a world ravaged by monsters, humanity fights back using special abilities gained through “Job Change” rituals—but this system creates a brutal hierarchy. Those who wield magic become rulers, while those who only swing swords are treated as commoners and looked down upon. In this age of division, a boy named Tatsuma Emori receives a single sword and a command from his adoptive father: “Become the strongest.” Yet at his fated Job Change ceremony, he’s branded a mere D‑rank Swordsman, earning only ridicule from those around him. Even so, the unyielding fire in Tatsuma’s eyes does not go out. With this sword, he vows to cut down the very “system” that governs the world.
