The planet that is home to the powerful Juraian family.
Jurai is the home world of the Juraian empire, and the birthplace of Ayeka and Sasami. The empire was formed many thousands of years ago, and its royal family's members are descended from a pirate guild formed by the families of several deposed noblemen. Over time, four separate houses or families formed; Amaki, Kamiki, Tatsuki and Masaki. Ayeka and Sasami's parents come from two of these houses; their father from the Masaki house, and their mother Misaki from the Kamiki. The Juraian empire is the most influential in the galaxy, and Earth is one of its many colonial planets. The leaders of the various Earth governments are in contact with the Juraian monarchy, but Jurai itself does not directly interfere with Earth politics. Members of the Juraian royal family own royal trees that possess special powers and act as control units for Juraian spaceships. Marriage between close relatives is common amongst the Juraian royal family (for example, Ayeka was betrothed to her half-brother Yosho).
