Previously on Assassination Classroom: 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 improbable means, and his mission is called off when Nagisa's group gets into trouble with the high school male delinquents. Later that evening, Red Eye is approached by Koro-sensei himself, who treats Red Eye to a meal, thanking him for making the field trip a valuable learning experience for his students due to his assassination efforts. Red Eye, understanding Koro-sensei's morals as a teacher, decides to quit his job in order to explore the world. Back at their hotel, private time among the boys and girls eventually turns into a hunt for Koro-sensei when he eavesdrops on their gossips. Koro-sensei hides from the students, telling Karasuma that the students wanted him to talk about his past love life. As the field trip comes to a close, the world government prepares two special assassins to transfer into Class 3-E.
Tonight: A new student joins the E Class with a singleminded focus on assassination that drives her classmates to distraction. Koro Sensei to the rescue!
