Kuchiki, Hisana

朽木緋真

She is the late wife of Kuchiki Byakuya and the older sister of Kuchiki Rukia. Hisana left Rukia as an infant because she could not support them both, a decision she regretted for the rest of her life. Byakuya Kuchiki married Hisana against his family's wishes due to their policy against marrying commoners. Shortly after their marriage, Hisana fell seriously ill and eventually died from her condition. On her deathbed, she begged Byakuya to find her sister Rukia and protect her.
