A young woman who talks with her mouth in murmurs and with few words. Fundamentally, she has a quaint and ladylike character, but because she was raised as a man, she is forced to be tough and strongly masculine and hides her “core” that is feminine. She is a little rebellious against authority, and fights with a dauntless courage on the battlefield regardless of her relationship to either gender. Mary is initially hard to approach while eventually "becoming more emotionally attached than anybody else upon opening her heart."
