There is scant information on the founding of Sorane other than the time period in which it was founded. It is presumed that a kunoichi by the name of Tsuzura Sayanaga defected from the village of Kirigakure, and subsequently entered into a partnership with the terrorist known as Shihakushi. This partnership engendered the organization of Sorane. The exact series of events which led to the formation of the syndicate, however, remain in the realm of speculation.
