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 with a smile on her face.
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.
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.
Soul Society arc
During the aftermath of the battle, Rukia is restrained by a member of the 4th Division when she tries to go to Byakuya's side while he is being healed. Captain Retsu Unohana, taking over the treatment of Byakuya, tells Rukia Byakuya is calling for her. Byakuya tells her about his deceased wife, Hisana, revealing Rukia is actually Hisana's younger sister. He recounts to Rukia about how Hisana had regretted abandoning her, and had kept searching for her while they were married. He reveals she asked him to find and protect her, as well as why he had sworn to always abide by the rules, thus leaving him torn between two promises when the execution was announced. He apologizes to Rukia for his actions.
Bleach movie 3
Walking into his chambers, Byakuya stops, prompting his attendant to ask if something is bothering him. Saying it is nothing, Byakuya goes through several rooms in his quarters. Seeing a desk with papers on it, he sees one of Rukia's drawings on the wood. Standing in front of a shrine, he looks at a portrait of Hisana Kuchiki. As he looks behind him, Kon states this picture is of Rukia. Turning around, Byakuya tells him to keep his voice down.
Apologizing for bothering him, Ichigo says he is trying to not cause a commotion here. Stating this is a picture of Hisana, Ichigo says she looks a lot like Rukia. As Ichigo asks if Byakuya has noticed something strange is going on, Byakuya's attendant sees him and moves away. When Byakuya asks what Ichigo is talking about, Ichigo tells him to not play ignorant and states Rukia is Hisana's sister, which Byakuya should know very well.
When Byakuya says her name, Ichigo states she is his younger sister-in-law, who he tried to protect even if it meant breaking the rules. Walking up to Byakuya, Ichigo says he does not remember her either. Turning to the shrine, Byakuya asks how Ichigo knew his wife's name was Hisana. As Ichigo begins to answer, the other doors in the room open, revealing Shinigami standing behind them. As they move in, Ichigo moves outside with Shunpo.
As Byakuya tells the Shinigami to stand down, Renji calls out to him and asks why Ichigo is here. Striking at Ichigo, Renji is blown away by Ichigo's attack, which creates a large dust cloud. Unsheathing his Zanpakutō, Byakuya utters the release command. After a tense moment, he reveals Hisana was born in the 78th district of Rukongai, Inuzuri. Thanking him, Ichigo vanishes. Elsewhere, at a park, Byakuya sits and recalls his past with Hisana.
In the past, Byakuya and Hisana walk over a bridge. When Byakuya asks if Hisana went to Rukongai again today, Hisana confirms this and apologizes. Stating it is alright, Byakuya says he knows why she keeps going, but he is concerned about her health. Apologizing, Hisana states it is something she feels she has to do. When she breaks into a coughing fit and falls to her knees, Byakuya expresses concern, prompting her to say she is alright.
Stating she is not, Byakuya says she needs to get some rest. Smiling at him, Hisana states she must continue her search, no matter how far she pushes herself. In the present, Byakuya notes she was searching everywhere, but he does not remember what she was searching for.
- (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."
