Hisana bore a very strong resemblance to her younger sister, Rukia. Like Rukia, Hisana was petite with pale skin and short black hair, though the strand of hair which fell across Hisana's face was slightly longer and more frayed at the end. Her eyes were colored purple with a hint of blue within them. She was often seen smiling, thus having a very gentle and delicate appearance.
Hisana was a kind, caring, and loving woman. She was soft-spoken and always polite. Hisana felt very guilty for leaving Rukia behind to save herself, feeling she did not deserve to be called her sister. She loved Rukia greatly, but could not care for the both of them.
Approximately 150 years ago,Hisana, along with Rukia, died in the Human World and was sent to Inuzuri, the 78th district of Rukongai. Unable to survive there while caring for a child, she deserted Rukia while she was still a baby. Later, Hisana married Byakuya Kuchiki. Hisana spent every remaining day of her life searching for Rukia, deeply regretting her decision to abandon her.
Five years after marrying Byakuya, Hisana died of illness one morning during the spring. On her deathbed, she asked Byakuya to find Rukia and protect her with his strength. She asked him not to tell Rukia she was related to her, as she considered herself unworthy to be Rukia's sister. For that reason, she wanted Rukia to be able to call Byakuya her older brother. Hisana, apologizing for being so dependent on Byakuya and being unable to return his love, told him the five years she spent with Byakuya were like a dream before dying.
Appearances in Other Media
Hisana's portrait appeared in the movie Bleach: Fade to Black. Byakuya, staring at her portrait, tells Ichigo Kurosaki the district Hisana had once lived in so he could find Rukia. It should be noted Byakuya did not know who Rukia was during this time, only learning from Ichigo Hisana was her sister.
Later, Hisana appears in a flashback in which she is walking with Byakuya in the grounds of the manor. Promising he will not stop her going into Rukongai to search for Rukia, he says he is concerned for her health. Moments later, she falls to her knees, coughing.
- (To Byakuya Kuchiki) "Byakuya-sama, please find my sister. Then after you find her, please do not tell her that I am her sister. Without telling her anything, please Byakuya-sama, please protect my sister no matter what. I abandoned her, so I don't deserve to be her sister, so I hope that she can be Byakuya-sama's sister."
- (To Byakuya Kuchiki) "Even at the end, I am still asking more of you. I am very sorry I couldn't return Byakuya-sama's love. I am sorry. Being with Byakuya-sama for the past five years was like a dream come true for me, Byakuya-sama."
