Carla Vargas is the daughter of Castor Vargas, granddaughter of Excel Walter, and friend to Liscia Elfrieden. She was formally the second-in-command to the Air Force of the Vargas Duchy and is currently a slave/maid to Kazuya Souma and Liscia. Like her father, Carla is headstrong and stubborn, with extreme pride. Though considered as very attractive, she has steadfastly refused all suitors, stating that she would never take a husband who was weaker than herself. She also shares her father's trait of leaping into battle without considering the consequences. (Source: How a Realist Hero Rebuilt the Kingdom Wiki)
