Saint King (聖王 Seiō), officially Heiliger Kaiser in Belkan language, also translated as Sankt Kaiser, was the title of certain hereditary rulers of Ancient Belka. Vivio Takamachi is a clone of Saint King Olivie Sägebrecht, created from the DNA of her shroud stored in the Saint Church. Olivie's surname is revealed in ViVid and she was the last generation of the Sägebrecht family. As the Sägebrecht family was just one member of the military Saint King Alliance, it is presumed that the former Saint Kings also had other family names.
