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!
Iruma-sama, why don't we try to 
strengthen your netherworld history?
إيروما-ساما، ما رأيك أن نحاول تعزيز معرفتك في تاريخ الجحيم؟
Iruma-sama! Was hältst du davon, wenn du dich
mehr auf Dämonengeschichte konzentrierst?
Don Iruma, debería centrarse
en estudiar Historia del Inframundo.

Maître Iruma, que direz-vous d’affiner
vos connaissances en histoire ?
Grande Iruma, perché non rafforziamo
 le tue basi di storia dell'Altro Mondo?
Iruma-sama.
Господин, почему бы вам
не уйти с головой с историю Преисподней?
