She gave up her aristocratic title in order to survive, and through her natural blacksmithing skills and hard work, Liliana became a court blacksmith at the young age of 15. One day, however, she is scoffed at as a ‘woman who stinks of iron’ by a hero whom she admires, and is banished from the court for a baseless crime. At a loss for what to do, she is picked up by a young swordsman, Glaive, who allows her to stay at his guild, the Sword of the Blue Sky. The court that banished her, on the other hand, is unable to repair the hero’s holy sword… This is the story of a lone girl who finds happiness.
