Two years had passed since the end of the Chikyu war and the six kings face another threat with the arrival of a new enemy force from outer space whom Kamejim is now working with. The leader of the new enemy force introduces himself as Spacebug King Dagdead Doujaldan, a self-proclaimed "King of the Universe", who determines to invade and destroy Chikyu. A new battle between the six monarchs and the new enemy force is about to begin.

Although the monarchs were able to return to their respective bodies, they are too late to learn that the Galactinsect's body switching plan was just a distraction for one of its jesters, Hilbil to brainwash not only the monarchs' respective retainers, but also their people to cause riots.
