Juliet is considered to be a very beautiful teenage girl by the members of the White Cats with straight hip-length blonde hair that has a black ribbon on the top left with square bangs hanging over her forehead while there are chest-length hair strands hanging on either side and azure blue eyes. She wears the uniform that represents the White Cats House with its white shirt and blazer. Juliet also wears white stockings and black shoes, just like any other uniform as seen in western schools. For her disguise as Julio, she wears a brown wig, brown eye contact lenses and the attire of Black Dog's middle school student. Because of her upbringing, Juliet is a very serious girl, but she has comical moments at times. She is a very confident person as she believes strongly in her abilities and doesn't like to be taken lightly or be looked down on by opponents. Despite being enemies of the Black Doggy House, Juliet showed genuine kindness to the children of the house and didn't retaliate when head-butted by one child for insulting them, though this was to motivate them to be stronger.
