I, Liz, was a holy maiden. One day, due to my half-sister Aria, who was supposed to have eloped to a neighboring country, returning as a beloved holy maiden, I was exiled and nearly killed. I used the devil king's secret medicine to turn into a child and escaped to the neighboring country, pretending to be someone else. However, I was picked up by Lord Dearsch, known as the Ruthless Duke. Fearing that I would be killed if my true identity was discovered, the people around me were kind to me. I learned that something terrible was happening in this neighboring country. It turned out that Aria's words, 'I wish the spirits would leave this country,' had made magic difficult to use. To repay the kindness, I decided to return to being an alchemist and help the duke and his people.
