Marina is Beatrice's mother. She also the headmistress of the school. She often leaves for a while, leaving her daughter to take care of the school while she's gone. But despite that, she loves her daughter more than anything in this world and is very protective of her and the school itself. Her late husband (Beatrice's father), created the school and now she is countinuing oh his behalf. 

Her voice should be mature, grown up, strong. Caring and motherly, but also the voice of a leader.
