The cliff incident was an incident resulting in the death of an unnamed servant of the Ushiromiya family as well as the mutilation of Sayo Yasuda. The incident occurs in every fragment other than the miracle fragment.
Kinzo Ushiromiya, after the death of his lover, Beatrice Castiglioni, became infatuated with his daughter, Beatrice Ushiromiya. Beatrice Ushiromiya strongly resembled her mother and Kinzo, in a state of madness, believed her to be the reincarnation of his dead lover. He forced himself on her and impregnated her. Beatrice Ushiromiya gave birth to Sayo Yasuda. In order to hide Kinzo's sin from the world, Kinzo and Genji Ronoue offered the child to Natsuhi Ushiromiya, who had been having trouble conceiving a child of her own. Natsuhi, distressed and angry at the offer, pushed the servant carrying the child, resulting in both the servant and the infant Sayo falling off of a cliff. The servant died upon impact with the rocky bottom, however Sayo miraculously survived. Unfortunately, Sayo sustained heavy injury to the abdominal and genital regions, resulting in severe mutilation.
