Welcome to Demon-School, Iruma-kun

Three giant magical beasts appear in Walter Park. Iruma, Asmodeus, and the others band together to face off with these creatures that ruined their fun day! Opera and Ameri fight against the giant rat while Jazz and his group are having some trouble dealing with the giant bull. He as well as other members in his group such as Lead and Camui don't have abilities suited for fighting, but Jazz comes up with a plan to turn things around!

The Balam team is trying to get to safety after saving some kids who weren't able to escape on their own in time. But then Asmodeus and Sabnock decide to fight the carmine dragon without telling anyone else. The two end up competing each other and fight the beast with their familiars. While they're fighting, Asmodeus ends up putting himself in great danger. What will come of the fight against Asmodeus, Sabnock, and the carmine dragon?

Ali-san forces Iruma to go through his evil cycle. His classmates are both in shock and admiration in how much more confident Iruma seems. Meanwhile, Iruma realizes how terrible of an environment the Misfit Class's classroom is, so he proposes something to Kalego. His proposal was to move the Misfit Class to the classroom with the utmost importance at Babyls, the Royal One! Despite the rather sudden and ridiculous request, Kalego agrees if Iruma is able to fulfill certain terms.
