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.
I can't tell by looking at it
whether it's strong or weak.
Nur vom Sehen kann ich nicht sagen,
ob es stark oder schwach ist.
Al verlo, no sé si será fuerte o débil.
Lo veo y no sé si será fuerte o débil.
Impossible de savoir
s’il est fort ou faible.
Guardandolo non capisco se sia forte o debole.
Não dá pra saber se ele
 é forte ou fraco só de olhar.
