Carla Vargas/Relationships

Castor Vargas
Castor is Carla's father. Castor is shown to be very loyal to him as she showed little remorse when fighting against Kazuya despite the fact that it would strain her bond with Liscia. Her loyalty was strong enough to the point that she immediately tried to kill Kazuya the moment she saw her father on the ground gravely injured and enslaved.

Excel Walter
Excel is Carla's grandmother. There isn't much known about their relationship, but Excel has shown that she cares for her granddaughter when she recommended to Castor to cut ties with his wife and children to ensure that they don't get tried for treason if he loses the battle.

Souma E. Friedonia
Carla didn't trust Kazuya at first but didn't say anything due to her friend's wishes. He eventually trusted her with ending his life should he become a tyrant.

Liscia Elfrieden
Carla is good friends with Liscia.
