Misa Kurobane (黒羽 美砂, Kurobane Misa) is Yusa Nishimori's elder sister who died in a motorcycle accident six months prior to the show's beginning. She was able to possess Yusa's body via her younger sister's Spiritism ability, but this is no longer the case after she and Yusa willingly gave up their abilities to Yū Otosaka.
