With scarlet hair and eyes, Kiefer is described to be a young pretty lady and stands slightly shorter than Ferris. She debuted in the story with short crop hair, but later in “The Legend of the Great Heroes of Legend”, three years after meeting Sion and Ryner in the Roland Royal Special Military Academy, she now sprouts shoulder-length hair. While appearing to be soft-spoken, she is bold in her feelings and has a caring heart. She is also portrayed as intelligent and relatively more skilled in magic than the average mage.
