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.

We missed all our chances for summer fun.
und wir hatten gar
keinen schönen Sommer!
Nos perdimos la diversión del verano.

Perdemos todas as nossas 
chances de diversão do verão.
