BYAKUYA: Rukia, are you there?
RUKIA: Yes, brother.
BYAKUYA: There is something that I need to tell you. It’s a 15-year old story. That year, I lost my wife before the first plums blossomed.
Rukia: I know. Lady Hisana. I was told that you took an interest in me because I greatly resembled your wife. That’s why I was accepted into the Kuchiki family as your sister.
Byakuya: That’s right. I instructed them to tell you that lie…Hisana was your sister.
