Meanwhile, the Magic Academy is preparing for its school festival, and Ard is asked to perform in a play in lieu of their Sword King Battle Tournament while also dealing with a threat to cancel the festival. Ard and the others start discussing the play when they're interrupted by a huge commotion at the school.
