Shiizaki has long black hair that reaches beyond her shoulders. Her frontal bangs also cover the majority of her forehead and eyes. While onboard <Fraxinus>, Shiizaki dresses in formal attire. She usually keeps a straw voodoo doll on her person at all times. Despite her seemingly rather creepy appearance, Shiizaki is actually quite nice. Often politely greeting people and she even told Shido to stay healthy after he had to undergo various medical checkups after the events in Volume 12. Despite being a member of <Fraxinus> crew, even she has her limits towards the perverted antics of the male members of the crew. She tells Minowa that they should examine all male crew members after their commentary during the Yamai sisters’ date with Shido.
