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!?
U-Um, I'm the only one 
on extermination duty today.
.عـ-عذرًا، أنا الوحيدة في واجب الإبادة اليوم
Ä-Ähm, eigentlich habe heute
nur ich Kammerjägerdienst.
Yo soy la única
que tiene que exterminar bichos hoy.
Yo soy la única
que tiene que exterminar bichos hoy.
Je suis pourtant la seule
de corvée de nuisibles, aujourd’hui.
E-Ehm...
E-Ei, eu sou a única encarregada
da exterminação de hoje.
С-сегодня на дезинсекцию отправили 
только меня.
