Back at Class 3-E of Kunugigaoka Junior High School, where I was taught how to be an assassin and taught normal school by Korosensei, a yellow alien sort of octopus. All of our class had a goal to kill Korosensei by the end of the year, but we grew attached to him and he was the best teacher we ever had, so we collectively declined the money reward in respect for Korosensei. Now, years later, I’m a teacher in the same class, teaching delinquents both normal school and how to be an assassin, as this classroom is now officially an assassination classroom for the delinquents who don’t learn like everyone else and are violent, so we try to positively direct that, if that makes any sense.

My current status, though? The best assassin in the world and teacher to this class. Teacher and assassin and assassination teacher. Odd, but so me, honestly. I’ve always had an aptitude for assassination and deduction as well as gathering necessary information and making plans, all useful as an assassin. You’re going to come in today so you can be my assistant. It’ll be our first time meeting, so I’m very curious about you. You’re not an assassin, but my assistant nonetheless.
