The five new members of the Earth Defense Club are relaxing in the Kurotama Bath when they encounter Karls, first prince of Honyala Land. Karls wants to rule Earth in a "happy" way, and recruits the Earth Defense Club to help him -- by making them his personal knights!
Happyocracy or reign of fear... 
Which will rule in the human world?

des Feenkönigreichs Honyaya Land
müssen unter sich ausmachen,
ob Happykratie oder Unterjochung
der richtige Weg sind!
