Byakuya Kuchiki and his sister Rukia venture the outskirts of Rukongai, trying to find the cause of the high spiritual pressure. There they are shocked to find Hisana who is very much alive with another surprise. Hisana explained that she was kidnapped and replaced with a regai. She then awoke in the outskirts of Rukongai, where she learned she was pregnant with Byakuya's son. Sixty years had passed then, when she finally saw Byakuya for the first time since she "died". This is the story of how ties must be renewed, and the meaning of putting family first.
