Class 3-E talks about Class 3-A's Big Five (Gakushū Asano, Teppei Araki, Ren Sakakibara, Natsuhiko Koyama and Tomoya Seo), an elite group of paladins. Irina joins the class as the magic teacher just to get the latest gossip. The students of Class 3-E disguises Koro-sensei as a scholar before Gakushū, who rides on horseback, and the rest of the Big Five show up at the classroom. After Gakushū fails to attack Koro-sensei with a Light Orb, Koro-sensei realizes that the Big Five was not sent by Gakuhō in the first place. This causes the Big Five to retreat.
