Koro-Sensei taught students the ways of living and how to be satisfied on education and not to give up. He motivated students into working hard and caring for them. Every moment and memories spent with Korosenei was like being with a friend forever and losing them forever. He loved his students and will cherish them in his heart. He helped students get over revenge, saving a person from falling down, trying to kill himself, and trying to kill him even thought they were going to die by tentacles.
Koro sensei's deah is by far the most painful death I've watched in anime. I've seen all the anime on this list but I believe Koro deserves the top spot. The execution, scenes, the pacing and most importantly the music made it even more emotional to the viewers. The anime made the audience feel like part of this fictional sensei's class. As nagisa drew the blade in, I felt so painfully close to the scene as if I lost a real person that I trully loved. This show made you empathize with the characters so deeply that I try to watch the scene at least once a day for the last week to test myself but in the end it still makes me shed tears. Assassination Classroom is definitely well executed.
I re-watched the two seasons so many time but not the last two episodes. I soon got to watching the last few episodes and needless to say, I was crying, and my parents questioned why I was crying over a fictional character. Its not only the character that stays in our minds, but their personality that stays in our hearts. I was kind of glad Karasuma and Irina actually finally called him Koro-Sensei AND respected him for saving both the entire world, but mostly their students. I would never want to feel the same pain Nagisa felt.
I'm surprised his death isn't in the top ten, even now I'm still mourning his death. We all knew it was coming, it's heavily hinted in the opening and it was Class 3-E's objective this whole time, and even so, I cried so hard. We were like a student in that classroom, the 28th student. We went through a year with Koro-sensei, learned with him together, learned his weaknesses together, and we assassinated him together. On episode 24 (S2) in the opening, it even says "congratulations on your graduation! " He knew it was coming, but he didn't act all sad about, he died with a smile, it really shows how much he loves his class. Forever in our hearts, Koro-sensei.
I just can't, all those good memories, I mean the plot was obvious that he was gonna die in the end, but adding his back story, those memories as they were killing me, how even in the end, he didn't want Nagisa to kill him in such way, yet he was happy to be killed by them, was really heart-touching, and watching his death always brings me tears.
Saddest anime death. I have dreams about Koro Sensei. Koro Sensei is my favorite anime character. His personality, how he looks, it's just perfect. And this creature dies on us. My life is ruined. Why couldn't he just live. Because the anime wouldn't have been as remembered.
Saddest death according to me. He taught students how to live. He was a humorous character and always cared for his students. The death scene was extremely sorrowful. I started sobbing. He indeed was the best teacher
Damn if there wasn't a time I cried harder because after two seasons in getting to know this experiment gone wrong human assassin. It just hurts I a lot when you realize he's dead and he won't be coming back.
After finishing Assassination Classroom I actually started to miss him. He was just so... AMAZING. He was so sweet to the students and seeing his death and the students' reactions just made me want to cry.
The death took forever and every moment just built up to the inevitable heartbreak. Everyone was crying and it was impossible not to join in on the tears with the characters we'd grown to care for.
This one of the saddest deaths on anime, he paid for his sins and his love but after all it was all about killing him. The memories or maybe the storyline is the why it's a sick
I've watched the final episode for two times and cried twice. It was really heartbreaking when Koro sensei, the greatest teacher in the entire universe was killed.
This is the saddest death I have ever experienced in anime, it is the only one I genuinely cried at. Some have made me shed a tear, but I was pouring with him.
He gave us a knife filled with our emotions, we stabbed him with that knife, and now all of our emotions are spilling everywhere
I wan on the series expecting that they would save his life but they killed him. What made it worse was that he calmed down nagisa before he got killed
Koro-sensei was a great, loving teacher who really changed the lives of his students. Arguably the best teacher ever. Rest in Piece, Koro-sensei.
I'm so sad because he's dead. I mean, he may be the 'villain' in the story, but that doesn't stop fans from loving him. He's a great teacher. But if he was still alive, and if Nagisa DIDN'T kill him, he would have blown up the earth and humanity will be destroyed forever. However its still bad that he died.
Only 10th? COME ON! It is by far the saddest. Anyone who voted for the others above him clearly have never seen Assassination Classroom. - DragonHarrier
I already knew that he's going to die since the first episode, because it's the main goal of the class. But since I watched it until the end I felt like I'm part of his class, I also learned many things from him and this show. Knowing that he'll die at the end but then at the end when Nagisa stabbed him and everyone was crying, including the toughest characters, and then I don't know why, but my tears just fell too. Then a day passed I still don't know what to do with life, because of the extreme sadness this anime gave me.
Would watch again and try not to cry.
It was the one and only anime I have cried to the most from all the anime I've watched so far!
I've watched it both in mange and anime for five times. Every time it left me in tear.
He really touches your heart as he died as one of the greatest teachers in anime.
He died knowing his students would carry on his legacy just like he did for her.
Why is this not #1? How many ever times I watch this, I cry so much
Definitely the saddest death of any anime
