She has long, pale blue hair that is clipped at the left side of her head at the front, while on the right it hangs loose and is cut somewhat shorter. She wears a Furisode kimono: The top part of her clothing has long sleeves that reach the ground, and the bottom part is also long and covers her feet.
Her manner of speaking is soft and peaceful, but personality-wise, she is cold and somewhat apathetic, unlike Rukia, who is sometimes stern, but kind.
She appears in the second session of the Bleach Breathless Collection with Rukia Kuchiki. Their two songs on the album are "Moon" and "Whiteout".
