Sara is the focal character of this arc and the Princess of Mysidia, although some don't think she acts enough like a Princess. When the group first meets her they think she's just some random townsperson that can be a bit opinionated. They are quite surprised to find out she's the Princess of the entire Kingdom. 

Sara has a huge heart and cares for everyone, even those who she doesn't know or those who have wronged her. In her eyes no life is dispensable. She would even give her own life if it meant protecting those around her. She wants to take over the kingdom to make her dads dream of a Kingdom with no social ranks a reality. 

She is in her early 20s I'd say but I picture her having a very strong and youthful voice. She can be a bit outspoken and does not always act very Princess like. I picture her voice being a bit of a medium tone, nothing too deep or too high. She needs to be able to emote though as the most important thing. She has parts where she screams in anger, parts she cries and parts she's very desperate. So whoever plays her needs to be able to fully capture those moments.
