When the Promising Generation was formed, it was to train the children of the CIA's best agents... the agents going after the Circle of Fifths. After attacking the Promising Generation, the Circle of Fifths disappeared.

Until the events of Royal Beginnings.

Now the members of the Promising Generation have grown up and can fight back. They will protect their own, and they will do their best to eliminate the Circle of Fifths once and for all.
