Appearance
By the words of Ruby, Shiranui is the first person most people think of when they hear "pretty girl" with waist-length black hair that she wears loose where her bangs are parted on either side, yellow-green eyes with slit-like pupils resembling a cat and two beauty marks; one on the lower right side of her lips and one under her left eye.

Personality
Shiranui appears to be an aloof girl of few words and is attentive to the careers of others, quickly recognizing Minami Kotobuki and Aquamarine Hoshino and remembering their previous jobs when she first meets them.

Another facet of her personality is her sense of humor, which has been referred to as "actually pretty funny." When it comes to acting, her demeanor can dramatically shift based on whatever role is assigned to her. Such versatility in covering a wide range of emotions and personalities is what enabled her to build strong connections and make a name for herself.
