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!
And the moment he took his place 
upon the Demon King's throne...
...ولحظة اعتلّ عرش ملك الشّياطين
Und als du plötzlich auf dem
Thron des Dämonenkönigs saßt,
Y en aquel momento…
Y en aquel momento…
Mais à cet instant…
E nel momento in cui si è seduto 
sul trono del Re dei Demoni...
E naquele momento...
А потом вы сели в кресло Князя…
и едва это случилось — я познал правду!
