Yukina Kawahiru (河昼 雪菜, Kawahiru Yukina) is a female Sōzōshin, which despite having distinct Kitsune lineage on her mother's side, was not passed on to her and instead she was born as a pure-blood. She is an offspring of the King of Souls, by way of Mimihagi, as the daughter of Tsuyuri Kawahiru. Yukina is the younger sister of both Kamui Kawahiru and Seireitou Kawahiru. As the only daughter of the Royal Family as well as the sole heir loyal to the King, Yukina is regarded as the Soul Princess (精神姫, Reihime; Viz "Soul Princess") of Soul Society. She is also the current head of the Kawahiru Clan.
