The Caerula Adamas plot a way to destroy the mysterious Battle Lovers. They also want to destroy the Defense Club, so as to cut down on club expenses. Thus, they declare that if the club members' scores on their final exams do not meet the average, the club will be dissolved. The Defense Club reluctantly gets to studying. Meanwhile, the student council also tries to scout the financially savvy Naruko to be their treasurer. When Gero offers him a salary during negotiations, Naruko casually agrees to leave the Defense Club. Soon, a monster appears, and the four remaining Battle Lovers must struggle to defeat it themselves.
And so, I think the student council 
requires a head accountant
Und deshalb glaube ich, dass der Schülerrat
einen Buchhalter benötigt,
Por eso, creo que el Consejo 
Estudiantil requiere un contador
Por eso, creo que el Consejo 
de Estudiantes requiere un contable
Et donc,
le bureau des élèves aurait besoin
E così, ritengo che il consiglio studentesco 
abbia bisogno di un contabile
Então, eu acho que o Conselho 
Estudantil precisa de um contador
