History does tend to repeat itself. The second world had equivalents of the characters represented there fighting Imu.
People kid themselves into thinking JB was the underdog when VP himself stated that the Ancient Kingdom was extremely mighty and likely way more technologically advanced than the other Kingdomgs, that and the allies he had.
Imu however tipped the scale likely with his Domi reversi ability turning some allies into enemies.
I fully think the 20 kingdoms werent aywhere close to advanced as the Ancient Kingdom (who likely inherited technology from the first world).
And Imu entity was sealed after the first world war as it lost then in the second world tempted the Nerona King into freeing him promising glory and riches. And once that happened he possessed the Nerona King and then went on to convince the other kingdoms to go fight the Ancient Kingdom with him.
Thus the second world war happened.
This third one however is the reverse, the WG is leading and the countries are subservient. We will see how that plays out.
