Reaper Time, Part 1.The students of Class 3-E notice that Irina's birthday was a few days ago, so they go see a florist to arrange for Karasuma to give Irina a bouquet for the occasion. However, the mood is spoiled when Karasuma casts aside Irina's romantic interest for the good of the mission, leading her to storm off. After Irina stops showing up at school for a few days, the students are suddenly snuck up upon by the florist, revealing himself to be The Reaper, who tasks the students to rescue Irina from being bound and gagged inside a dungeon. The Reaper lures the students into his trap at a fortress, but they attempt to escape and find Irina. Some students are taken down by The Reaper one by one, and even Nagisa is thwarted by his clap stunner. Meanwhile, the remaining students manage to find Irina, but they discover that she has turned against them. As all of the students are recaptured, Koro-sensei and Karasuma begin their rescue attempt.
