The sword of my closest friend and trusted lieutenant stabbed my body. When I opened my eyes again, I had become a Lady, an aristocrat of the enemy country. In this unfamiliar and fragile body of a stranger I had already lost 3 years, during which my country turned into ruins. At first, I was unable to regain my sense due to the pain of betrayal and the confusion of identity. However, I decided to live, as Lucifella Aidin, as a Lady Aristocrat with a sword.
