Under Karasuma's instructions and with the help of the students, Red Eye sets up to snipe Korosensei when the former was having a tour on board the Sagano Scenic Railway with his students. When the train stops on a bridge overseeing Hozukyo Gorge, a student named Hinano Kurahashi distracts Korosensei by pointing at a passing boat. As Korosensei leans out of the window to look at the boat, Red Eye takes his shot only to discover that Korosensei somehow managed to stop the bullet by using a yatsuhashi.
