Prior to their trip, biologist Hinano Kurahashi helps Nagisa and the others hunt for bugs while pervert Taiga Okajima lays out his own trap for Koro-sensei using a pile of porn magazines. Later, Lovro is called in to train the students for their island assassination, taking interest in the class' two top marksmen, Ryonosuke Chiba and Rinka Hayami. During the training, Lovro tells Nagisa about the world's most infamous assassin, known only as "The Reaper", and decides to teach him a surefire assassination technique. The class soon arrives at their island resort, making all the necessary preparations for their assassination. After having dinner, during which Koro-sensei inadvertently uses up his emergency shedding technique to get rid of sunburn, the class begin their assassination aboard an on-sea chapel.
