Fran is a young woman with a strong familial resemblance to her sister, Noel. She has tawny brown hair worn in two short twin tails and hazel eyes. Fran is usually seen wearing her Crossbell Police uniform, a blue and green skirt suit with black tights, grey shirt and red neck-tie. She wears a small pillbox hat in navy blue and heeled pumps.
She really looks up to her older sister Noel, who is a member of the Crossbell Guardian Force. A cheerful and bubbly personality, she is extremely helpful to stranger and sometimes gives to the appearance of being naive, despite being quite cunning and perceptive. Unlike from her sister, Fran has a weakness for cute girls, like KeA and Shizuku MacLaine, and stuffed animals.
Fran Seeker is a female receptionist at the Crossbell Police Department and operator for the Special Support Section. She is very close to her sister, Noel Seeker.

This would mean she would be opposing Noel, who had since joined the Crossbell Defense Force. Fran felt that she could only make a difference in Crossbell as a police officer and therefore had to oppose her sister.
