The Misfit of Demon King Academy Episode 10

Inter-Academy Exams (学院別対抗試験) is the tenth episode of The Misfit of Demon King Academy anime series.

Synopsis
Anos and the students from Demon King Academy participate in their first day of inter-academy exchange with the Hero Academy. However, the students from Demon King Academy soon find out that the inter-academy exchange is in name only, and they are met with outright hostility. Revest, a third-year student at the top of his class from Demon King Academy is ridiculed by the students from the Hero Academy when he unsuccessfully tries to activate a magic spell. The students from Demon King Academy are visibly offended by this treatment, but Anos’s words turn the tables. “As usual, humans sure like to set traps for us, don’t they?” The inter-academy exchange is off to an ominous start.

Anime Differences

 * It is said in the web novel that those wearing scarlet uniforms are from the Selection Class "Jerga Kanon", thus there weren't many when Anos looked around the auditorium. But in the anime, there's about the same amount of students wearing scarlet uniforms as there is wearing blue.
 * In the web novel, the competition was in the form of a trivia game, not a magic demonstration.
