Shiro is a Kitsune with long white-silver hair, ears, and tail, as well as red eyes. She also sports two red stripes on both of her cheeks.

Shiro wears a long white dress with a crescent moon on one side revealing one of her legs, as well as black stockings and shoulder-length gloves. She has a red ribbon-like scarf she wears around her lower back. Along with that, she has a black neck collar with a red gem hanging from it.

Shiro is initially arrogant when she first is introduced, believing that Kuroto should be her servant and worship Kitsunes. She is often much more energetic and unpredictable than Senko. She later becomes friends with Kuroto and Senko.

Shiro is initially sent to assist Senko with Kuroto as she is seen having trouble removing his "darkness." She later becomes Yasuko's roommate.
