Hisana Kuchiki

was Rukia Kuchiki's sister and Byakuya Kuchiki's wife. She was forced to abandon her baby sister, Rukia, in the 78th district of Rukongai, in order to survive. She sometime thereafter married Byakuya. The people of the Kuchiki clan were against their marriage, as marrying someone of Rukongai seen as the wrong thing to do in the Kuchiki family. Hisana spent every remaining day of her life searching for Rukia. Hisana later died of illness on the Spring of the fifth year, but on her death bed, she asked Byakuya to find Rukia and adopt her into the clan, but not to tell her she was related to her, as she considered herself unworthy to be her sister.
