Switzerland, also known by her human name of Claritta Marlise Keller, is a gentle and intelligent young woman who has a great understanding of people and how to protect herself.

Switzerland is a very smart person and has a great understanding of people and how they work. She does not let her morals and beliefs be compromised, yet still understands how to interact with people in a way that allows her to benefit without harming herself. She can sometimes be called manipulative, but she tries not to be, simply keeping herself and her cantons neutral without having to give herself over to others.

Switzerland can be very gentle and a bit of a pacifist, not wanting to get involved in fights if she can help it. Part of this was built on the trauma of her childhood and her experiences as a puppet state, but she does not believe that war helps fix problems, instead causing more. She can sometimes come off as naive, but she knows what she is doing.
