Naomi is a shy fortune teller who operates her business in the Natsuki Building, the same apartment complex where the main character Masane Amaha and her daughter Rihoko live. Her extreme shyness around strangers and her sensitive nature often deter potential customers, harming her fortune-telling trade. She is frequently the target of good-natured teasing from a resident known as Mr. Cho. Naomi has long black hair and brown eyes, and her appearance is commonly described as gothic, often wearing a dress with a cross motif. As a supporting character, her role in the story is largely that of a neighbor and a minor figure within the building's community. She does not become directly involved in the central conflict surrounding the Witchblade or the organizations fighting over it. Her primary motivation appears to be a desire for a quiet, peaceful life and to manage her small business despite her social difficulties. No notable character development or special abilities beyond her fortune-telling are prominent in her portrayal; she remains a secondary presence who contributes to the slice-of-life atmosphere surrounding Masane and Rihoko's daily life.
