To avoid failing, Iruma works with Asmodeus and Clara to study!

Clara isn’t amused at the fact that Ameri keeps summoning Iruma. To try to get Iruma to pay attention to her again, Clara starts to take succubus charming lessons with the succubus teacher Raim.

Asmodeus is sent to the New Magic Battler, Clara to the Game Battler, and Iruma joins the student council. Iruma now has to face the grueling training and schedule of the student council. Meanwhile, something sinister is after Ameri...

The Misfit Class is in the middle of a flying race in order to determine their ranks. Since Iruma is human, he can’t fly, so he’s riding on the back of the giant baby demon bird, but it seems to be flying off course. Meanwhile, Sabnock decides to go through the treacherous Cutthroat Valley and ends up having to battle it out with the Guardian there. Sabnock is obsessed with becoming the next Demon King, but why is he so obsessed? Are Iruma and Sabnock going to be able to make it out of Cutthroat Valley alive?
