Welcome to Demon-School, Iruma-kun S02E09 - Studying in the Netherworld
Summary:
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!
