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...
They never change.
Immer das Gleiche mit euch.
El Club de Defensa de la
 Tierra nunca cambiará.
El Club de Defensa de la Tierra
Ça ne m’étonne vraiment plus,
venant du club de défense de la Terre.
Non cambierà mai...
Eles não mudam nunca.
