Kaya features a highly distinct, slightly disheveled design that matches her opportunistic nature. She has long purple hair that completely covers one of her green eyes, giving her a perpetually suspicious and calculating aesthetic. She wears the standard Fūrin High School uniform but accessorizes it with a white lab coat, instantly separating her visual silhouette from the rest of the student body. She is almost never seen without her professional-grade DSLR camera suspended around her neck.
