Overview
It's finally time for the long-awaited school trip to Kyoto. Class E has planned an assassination for this trip. But, amid preparation and inspections, Kayano and Kanzaki are kidnapped by high school students from another school. Will they be able to save them!?

Summary
The students of Class 3-E prepare for a field trip to Kyoto, which is also being used as a venue to assassinate Korosensei. The students are arranged into groups, in which Nagisa, Kaede, Karma, Sugino, Manami and class idol Yukiko Kanzaki agree to be in a group. On the train ride to Kyoto, high school male delinquents steal Yukiko's itinerary noting the group activities. On the next day, the group visits all the assassination landmarks, but they are ambushed by the male delinquents, who kidnap Kaede and Yukiko. Whilst in captivity, Yukiko laments to Kaede about her rebellious acts due to being raised in a strict family. Nagisa, Karma, Sugino and Manami manage to use an extensive guidebook written by Korosensei, which provides a thorough procedure for hostage situations, to deduce where Kaede and Yukiko are being held. Korosensei arrives to deal with the delinquents, while Nagisa and the others knock out the delinquents with their guidebooks. Following the incident, Yukiko is encouraged by Korosensei's words of wisdom, in which those with the will to drive forward will come out strong regardless of situation or status.

Episode Notes

 * Instead of the usual 3-E Song Unit members singing the opening, Ryota Ohsaka (Isogai) and Shintarō Asanuma (Maehara) are replaced with Yoshitaka Yamaya (Sugino), Satomi Satō (Kanzaki), and Sayuri Yahagi (Okuda) for the episode.
 * The singers for the episode also happen to reflect Nagisa's group for the Kyoto trip.

Differences between the Manga

 * In the anime, Korosensei dressed up as a maiko (apprentice geisha) to note his excitement whereas in the manga he simply had his massive luggage to show. This is a call forward to one of the later manga chapters which showed Korosensei dressed as a Maiko on the front color page.
 * In the manga, while boarding the train, only Nagisa's old classmates comment on Class E riding the regular cars, whereas in the anime their teacher is included in that scene.
 * When Class E arrives at their hotel, in the manga it's only Okano who tries to stab Korosensei, whereas in the anime it's her along with Isogai and Kataoka.
 * In the anime, Karma knocks one of the high school delinquents to the ground and then fends off another one who had a knife before being knocked unconscious and beaten whereas in the manga, he knocks one of them into a pole before being simply knocked unconscious.
 * Also, the scene following after that shows Kayano and Kanzaki in the car with the thugs is removed in the anime.
