Rukia and Byakuya Kuchiki may not be blood related but they have something more than that, they’re powerful and amazing as one which puts them on another level. Rukia thinks of Byakuya as a bigger brother while Byakuya to Rukia as her little sister that he never had. It has been a really sad past for both of them, especially when Hisana had left her when she was young.
