"Have you ever danced with the Devil on a pale moonlit night?"

is an elusive, enigmatic Shinigami from one of the early five noble families of Seireitei, and thus, current leader and heir to her clan- she and her family were the ones responsible for creating Kikōō, the true form of Sōkyoku, and it is known that she served in the Kidō Corps. It was thought that her whole kin, her included, were massacred, but she is apparently the sole remaining survivor- having been thrown in Hueco Mundo and during that time, she managed to absorb her Zanpakutō in a bid to survive, which resulted in an enhanced proficiency in kidō. That makes her the only Shinigami to develop and procure such augmented powers through such means and the only Shinigami who acquired the ability to merge with and detach her Zanpakutō at will. Later it is revealed that she is also the keeper, guardian and by default, the owner of Sōkyoku’s true form and power- Kikōō, and the only one who can harness its potential.
