Diana, the second daughter of the prestigious noble Ashleigh family—renowned for producing exceptional knights for generations—was raised in comfort and protected as a proper sheltered young lady. However, after her elder sister, the female knight Luna Ashleigh, suddenly ran away and went missing, their family was scorned as a “disgraced bloodline with a runaway,” and their influence within the Imperial Army declined day by day, leading to their fall from grace. Watching her father, Robert Ashleigh—commander of the Imperial Army’s knight order—suffer in silence and grow thinner each day, Diana, deeply loving her father, began wondering if there was anything she could do for her family, and for him most of all. While struggling with these thoughts, she learned of “adventurers” and the “Adventurer’s Guild,” and resolved to become one herself, without telling her father. Thus begins Diana’s journey, where many encounters, partings, and a harsh destiny await her―――
