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!
It's fine! I need to get better at my 
netherworld history, like you said!
!لا بأس! أنا بحاجة للتحسّن في تاريخ الجحيم كما قلت
Keine Sorge! Du hast es selbst gesagt,
konzentrieren wir uns auf Dämonengeschichte!
Tranquillo! Devo migliorare 
in storia dell'Altro Mondo, come dicevi!
Да нет, зачем?
Ты же сам говорил, надо заняться историей!
