Assassination Classroom Episode 10 English Dubbed Episode Title:L and R Time.Episode Description:Irina is caught off guard by retired Russian assassin Lovro Brovski, her former master, who advises her to give up trying to kill Koro-sensei. Instead, Koro-sensei proposes a match between Irina and Lovro to see who will be the first to "kill" Karasuma with a rubber knife, offering Karasuma his own incentive should neither of them win. Despite Lovro's doubts after he fails to "kill" Karasuma himself, Irina manages to use what she has learned targeting Koro-sensei to get close, with Karasuma accepting defeat at her hands and Lovro acknowledging her efforts. Nagisa, Karma and Ritsu later agree to accompany Koro-sensei at Mach 20 speed on a trip to Hawaii to watch the premiere of a new movie, getting a lecture along the way and learning a lot more about Koro-sensei's point of view. On their way back, a man in a white cloak observes alongside a boy, the second transfer student who claims to be Koro-sensei's younger brother.
