Synopsis

In a peculiar world, all things revolve around Cards, from daily necessities to fierce warfare. Those who manipulate Cards for battle are known as Card Cultivators, while Card Crafters are responsible for creating them. However, for Cards to achieve their ultimate power, suitable Card Ink is required—a type of ink difficult to concoct and fraught with danger. It is precisely for this reason that a special profession emerged: the Ink Alchemist—one who specializes in mixing Card Ink. Card Cultivators, Card Crafters, Ink Alchemists, Cards, and Card Ink are all divided into Nine Stars, from the lowest First Star to the highest Ninth Star, defining the hierarchy and power within this world.
