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!
Not to mention, Iruma-sama is very earnest.

Тем более что юный господин —
человек серьёзный.
