While the other groups are accompanying Koro-sensei on a tour of Kyoto, a sniper known as Red Eye is tasked with assassinating him at various spots. However, each of his attempts to shoot him are thwarted by improbably means, and his mission is called off when Nagisa's group gets into trouble. Later that evening, Red Eye is approached by Koro-sensei himself, who treats him to a meal and gives his thanks, stating his assassination efforts made the trip a valuable learning experience for his students. Understanding Koro-sensei's value as a teacher, Red Eye decides to quit sniping in order to see the world. Back at their hotel, private time amongst the boys and girls respectively turns into an octopus-hunt when the gossip-loving Koro-sensei eavesdrops on their conversations. While hiding from the students, Koro-sensei and Karasuma talk about romance, briefly hinting about Koro-sensei's past. As the school trip comes to a close, the world government prepares two special assassins to transfer into E Class.
