After pulling the plug on the space reality TV show "Can I Destroy the Earth? 2," the Defense Club and the Conquest Club return to their peaceful high school lives. Time has passed since that fearsome battle, and it's now autumn. The five Defense Club members have stopped serving as the Battle Lovers, and are enjoying a soak in the Kurotama Bath like always, when the Conquest Club broaches a subject that will change a great deal about events to come...
Hey, quit getting sand 
all over the club room!
Mann! Hört auf,
den Raum einzusanden!
¡Oigan, no tiren arena 
en el salón del club!
¡Jolines, no tiréis arena 
en la habitación del club!
Arrête de mettre du sable
partout dans la salle de club !
Ehi! Smettila di buttare sabbia in giro 
nella stanza del club!
Ei, pare de jogar areia  pela sala do clube!
