First Period: Summer Festival Time

After the failed assassination and the Takaoka ordeal, Class 3-E enjoys a final night on the island. Korosensei stages a courage test that pairs the students by gender, secretly hoping to stir up romance. Nagisa and Kayano go first and get spooked by a local ghost tale, though the effect wears thin once they overhear him repeating it to the next couple. Farther in, Karma confesses to Okuda that Nagisa's calm after beating Takaoka unsettled him, since a fighter craves victory while an assassin finds it hollow.

The plan backfires when the second half of the class frightens Korosensei instead. The students then reveal they saw through his scheme from the start and scold him for engineering fake romance. Just then Irina and Karasuma emerge from the cave visibly annoyed with each other, and the class senses an opening.

Back at the hotel, Irina admits that while trying to seduce the oblivious Karasuma she genuinely fell for him, leaving her flustered. The students and their teacher rally to help. Nakamura suggests she dress modestly like Kanzaki, but the borrowed outfit only makes her look more provocative, and Okano notes that compatibility matters more than skin. Reading Karasuma as plain and military-minded, they arrange a private dinner with Irina in clothes made by Hara. Despite her complaints about the venue and the spying crowd, she enjoys herself, until she raises the subject of killing and, unnerved by her past, walks off cursing herself as Karasuma stays utterly dense.

On the final vacation day, Nagisa lunches with his father before Korosensei drags him to a last-minute summer festival. Elsewhere, Lovro, pleased that Nagisa mastered his technique, is ambushed and shot in the chest by a stranger reciting a poem. At the festival the students have fun, Chiba and Hayami are barred from the shooting stalls for winning too often, and Nagisa realizes the class is quietly funding Korosensei, who runs several food stands at once. With the group nearly cornering their teacher earlier, officials raise the group-kill bounty to thirty million yen.

The episode launches the second season and adapts chapters 74 through 76. It also debuts the third opening theme, QUESTION. In one manga difference, the discussion about pushing Irina toward Karasuma happens on a terrace rather than in the lobby. It premiered in Japan on January 7, 2016, with the dub on February 11, 2016.
