Kabuki's origins are revealed as the story progresses, her mother was an Ainu comfort woman named "Tsukiko" taken by Japanese soldiers during WWII. Rather than be used as sex slaves, the General instead had the women act out Kabuki plays to entertain the soldiers, something that was met with scorn by his son, who fast made "Kabuki" a derogatory term among the ranks. Tsukiko in particular captivated the General, a widower, who took her to be his wife. This decision infuriated Kai, who saw it as an affront to his deceased mother. On the eve of their wedding, he assaulted, raped, blinded and savagely scarred Tsukiko with the words "Kabuki" into her back. Tsukiko survived the encounter, and she was pregnant with Kai's child, something the General kept hidden. Tsukiko dies while her daughter Ukiko is being born. The General in turn raises her as his own daughter. Nine years later, Kai, still demented and vicious, learns of the child's existence and savagely attacks Ukiko at her mother's grave, once again carving "Kabuki" into her skin, this time along the girl's face. Ukiko dies for nine minutes but is successfully resuscitated. From then on, the General grooms her into a perfect soldier, having her trained in martial arts, combat and weaponry so that she may never fall victim to another assault. When the Noh is created, she is given a mask reminiscent of her mother's face and the codename "Kabuki" – claiming the term as her own.
