Iruma is trying keep a low profile in front of the demons, but Sullivan shows a poster of Iruma, boasting about his grandson. He even calls Iruma to give a speech instead of the freshman representative.

Iruma finds a letter on the podium and reads it aloud, it is revealed that what he just read was a forbidden spell and if he had mispronounced even a single word, his body would have blown to bits.
