The students are about to welcome their version of summer vacation! The Misfit Class is super excited but then, they're reminded that if they don't do well on the end of terminus exams, they'll have to stay for supplementary classes during their break. To avoid that from happening, they all want to avoid failing. But Iruma is a human and has very little knowledge concerning netherworld wisdom. To avoid failing, Iruma works with Asmodeus and Clara to study!
They cannot panic and wave around 
their swords during a battle!
!لا يمكنه أن يهلع ويلوّح بسيفه يمينًا ويسارًا أثناء القتال
Es kommt nicht infrage, vor einem Krieg
wild mit dem Schwert herumzufuchteln!
No se puede combatir si entras en pánico
justo antes de empezar.
No se puede combatir si entras en pánico
justo antes de empezar.
Ça ne sert à rien de paniquer
et de sortir son épée avant la bataille.
Non può andare nel panico
 e sbatacchiare la spada in battaglia!
É fora de questão estar apressado para tentar
balançar sua espada antes de uma guerra.
А вот махать кулаками перед битвой —
сиё есть недостойное поведение!
