Katie is a young woman, being 18 years of age, with chin-length purple hair with a few bangs nearly covering her right eye and spiking up on the left and Periwinkle eyes. Her body is slender but hiding small muscle underneath, as well as being a person of average height.
She wears the standard Rose Knight armor consisting of black under chainmail clothing with silver and gold armor, and a mini white cape behind her back.
When she’s not wearing armor, she usually wears a black tank top, brown pants and black boots and brown gloves.
Afterwards, she changes her armor of a purple and red armor stylized like her old one. She soon wears a black waist cape as well as a purple cape over her left shoulder.
As a child, Kaie was an energetic child who would easily get bored unless something exciting happened.
As an adult, she became a woman with great respect towards her superiors. She is also very kind and accepts orders from higher-ups without hesitation. She had a strong dislike for goblin and hobgoblins, but her views change when it was Rouhan that helped her and the other captives from being turned into mindless playthings.
When Katie was first introduced, she was shown to have a calm, quiet, and serious demeanor, putting her mission first and only speaking when necessary. She was also very cold, bordering on heartless, as she called Kalua an abomination from being the spawn of a Holy Priestess and even went so far as to try and kill her. She later threatened to do the same to Rouhan when he was technically the same thing. After Rouhan defended not just getting their new home as well as saving her from being raped by Tazaar, however, she gains a very close relationship with Kalua, being touched by her kindness and apologizes for calling her an abomination when they first met.
While a faithful member of the Knights, her beliefs are flexible enough to accept help from a Hobgoblin such as receiving a free lunch, and wanting to not only accomplish their mission, but survive afterwards as well.
In battle, Katie appears to be a bit arrogant, stubborn, and rarely using her head and attempting to overwhelm her opponents with pure power and strength instead of being subtle or using skill. According to Rouhan, her fighting style is comparable to that of a Rook despite being a Knight. As Katie was raised in the Church, she lacks common knowledge on the life of a normal person, evident when she began to strip in front of Rouhan, as well as wanting to give birth to strong children, and has chosen Rouhan as her mate. As the series progresses, it is shown that Katie has developed genuine romantic feelings towards Rouhan due to him protecting his comrades even if he gets injured by doing so.
