Marta tends to think along a fully defined line of right and wrong. As a bit of a tomboy, Marta is passionate about getting her way. On the left side of her forehead lies Ratatosk's core, in which Ratatosk is imprisoned in a dormant state. Emil became her guardian knight, a Knight of Ratatosk, in order to protect her and Ratatosk's core. Marta falls in love with both Emil and "Ratatosk Mode" Emil. As the game progresses, she begins to love Emil for who he actually is, instead of the fantasy she created in his image. Marta also gets very jealous when Emil tries to get along with other girls, stating that she shall not give up on getting Emil's heart. Being the romantic that she is, Marta will fully support anyone's attempts at a relationship as long as it is not directed toward her or Emil.
