Hmmmm, in Devil's page it is said that If i am not mistaken, Ultimate Class only can be achieved only by great achievements, right ?? not bloodline like heir of a clan, because if it is about bloddline then Rias is supposed to be considered as Ultimate class not High class Devil.
 * Ultimate-Class Devils (最上級悪魔 Saijōkyū Akuma): Includes Satans, Great Kings, Kings, Archdukes, Dukes, Prince/Princess, and Devil clan heirs/heiresses.
