Rukia Kuchiki (朽木 ルキア, Kuchiki Rukia?) is the younger sister of Hisana Kuchiki. Though talented enough for a position as a seated officer, has been made ineligible by order of her older brother, Byakuya Kuchiki, out of concern for her safety. However, this is not revealed until after the Soul Society Arc when the Arrancar and Espada first appear. Her zanpakuto's name is Sode No Shirayuki, also known as the most beautiful sword in the Soul Society. Not known to have bankai however the materialised Sode no Shireyuki in the Unknown Zampakuto Tales arc possessed abilities non seen with Rukia such as freely controlling icy winds and creating icicles to attack but no link was made between this and a potential bankai. In the Substitute Soul Reaper Disappearance arc, Rukia is now the lieutenant for squad 13.
