While normally calm and serious, Crusch is honest, sincere, righteous, being the type of person who is destined to stand above others, though she has talent, and has worked hard to reach where she is now. She is already the head of her family, finishing her work better than her father. She prefers to act herself and has the pride of a warrior. Crusch is also gentle, often believing the false knowledge jokingly told to her by Ferris, and sometimes displays an air-headed side. Like her mother Helena Karsten, she is shown to be ruthless and reckless. Crusch is also dense toward any feelings of love above kindness, often not understanding why certain people behave a certain way, such as when she sometimes didn't understand Fourier's behaviour. However, this only applies to feelings of love directed towards herself, as she has been shown to comment on the feelings of others. Crusch is described as a beautiful woman with almond-shaped amber eyes and long dark verdant-green hair that reaches down to her lower back. Even though she is a woman, she generally tends to dress as a man (or at least very formally). Unsurprisingly, her impression changes if she wears a dress and smiles. Crusch Karsten is the current head of the Karsten House as well as a candidate for the 42nd King of Lugnica. She has been described as beautiful with amber eyes and long dark green hair that reaches to the middle of her back. In his time under her care over a few days Subaru only saw Crusch in a dress once. She is in fact much more likely to be seen in clothes traditionally considered more masculine. Her attire when working is that of a long coat over a dress shrit and pants reminiscent of a commanding officer in an army. Daughter of the former Duke Karsten, she was raised in high society, where she grew to love the sword. Befriending both Fourier Lugunica and Ferris, she became incredibly popular among her people, eventually coming to be known for her skill on the battlefield as the Valkyrie and in office as the next Duchess. Following the demise of the royal family, which included Fourier, she was discovered to be a candidate in the Royal Selection. Crusch already asked her father for a crested dagger. As she grew older, Crusch would develop a preference for men's clothing, and take on more masculine pursuits like learning swordplay which earned rumors about her from other nobles. Felix is also her second in command
