The Royal Emperors is a group of basketball geniuses who are thought to be the only equal of the Successors of the Miracles. Despite being their equals, this group was overshadowed by the members of the SoM. If these players had been born at another time, they would have been hailed as miracles. They're individual skills were overshadowed by the collective efforts of Teiko Junior High. The Royal Emperors are also known as the Divine Kings.
The Royal Emperors were very different than the SoM because they played at different middle schools. Their identities were revealed in the prologue of the new series.
