In order to protect the school grounds from the ever present threat of the bugs, today it's Arsnotoria's turn to be on extermination duty.
Mell, Little Alberta, Picatrix, and Abramelin all rush to her side to help her with this activity.
But then, one word from their shadow cat teacher Perdura puts the entire school into a frenzy!?
Abra, is the sword on your back 
just for decoration?
أبرا، هل السيف على ظهرك للاستعراض فقط؟
Abra! Ist das Schwert an deinem
Rücken etwa nur Dekoration?
Abra, ¿acaso la espada es de adorno?
Abra, ¿la espada es de pega o qué?
Abra… L’épée dans ton dos
ne sert qu’à décorer ?
Abra, questo spadone sulla schiena
ce l'hai per bellezza?
Abra, essa espada aí nas
suas costas é só enfeite?
Абра, этот меч у тебя за спиной
только для красоты?
