Kiefer Knolles

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.

Kiefer is of Estabul origins, and at the age of fourteen, after Estabul had already become a vassal country of Roland, she witnessed the death of her elder sister under the hands of Roland's mage knights during the rule of the former tyrannical King of Roland, while her elder sister tried to protect Kiefer and her younger sister. In order to save her younger sister, the last of her remaining family, she agreed to become a spy for Roland while her younger sister was taken hostage. While pretending to work as a spy for Estabul and infiltrating the Roland Royal Special Military Academy, she is in fact a double agent working for Roland, and as such is versed in both Estabul and Roland magic.
