Crusch Karsten (クルシュ・カルステン) is the head of the Karsten House and a candidate to become the 42nd King of Lugnica. She is the Matriarch of House Karsten.
Crusch is a beautiful woman with amber eyes and long dark green hair that reaches to the middle of her back. Even though she is a woman, she generally tends to dress as a man, and is described to be someone whose impression changes if she wears a dress and smiles.
Currently Crusch is infected by Capella's Authority, covering her body with black veins.
While normally calm and serious, Crusch is honest, sincere, right, being a 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 airheaded 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 behavior. However, this only applies to feelings of love directed towards herself, as she has been shown to comment on the feelings of others.
Because of the time she spent with Fourier, she has strong feelings concerning the Lion King (獅子王 Shishiō), a title formerly owned by the first king who made the pledge with Volcanica.
Currently Crusch has had her memories eaten, making her become amnesic. Despite this, she shows a strong minded side, vowing to become much more of a person than she previously was. In addition to this, she is infected by Capella's dragon blood.
When Crusch was a child, she encountered Fourier at the castle, almost attacking him with the knife her father gifted to her until he revealed who he was. Since then, he became one of her few friends, though he died when he was 20 from an unknown cause. His death influenced her to compete in the royal election to become the next king.
Divine Protection (加護 Kago): Crusch has the Divine Protection of Wind Indication (風見の加護 Kazemi no Kago). It enables her to read the wind and to see invisible things just like the wind. Crusch can also use it to read the situation of others' emotions, making her able to tell if someone has lied.
Wind Magic: Crusch is highly skilled at Wind Magic, allowing her to combine it with her sword skills for devastating results.
- One Blow, A Hundred Felled (百人一太刀 Hyakunin Hitotachi): Crusch combines her sword skills and Wind Magic to unleash a sword strike that enables her to cut anything within her range of vision with an invisible blade.
Skilled Swordsman: Crusch is considerably skilled at using a sword in combat, or using her Wind Magic to act as one.
- According to the author, Crusch's birthday is April 4.
- She remarkably sheltered when comes to romance or at least when it is directed at her.
