The God of Death, also known as The Reaper, is a major and the final antagonist in the Assassination Classroom series. He was a protégé of Korosensei.
Once Kaede fails as well, he reveals himself as Kōtarō Yanagisawa, the lead scientist who performed the experiments that transformed the God of Death into Koro-sensei and destroyed the moon, thus making him the primary antagonist of the series.
In general, Korosensei has a good relationship with all his students, helping by doing anything he can. As a result, he is highly respected by them. His positive relationship with the class stems from his promise to their former teacher Aguri Yukimura to give them courage and not let any of the students fall behind.
Koro-sensei takes one final roll call, as he reminisces his great experience as a teacher. Although Nagisa shakes with his knife in hand, Koro-sensei calms him down, allowing Nagisa to deal the killing blow to the heart as Koro-sensei's body turns into light and the students then mourn.
Due to the human experiments of producing antimatter in a living body by Shiro, Korosensei's entire appearance is of an octopus-like creature with multiple tendrils that are his tentacles.
The government saw him as a secret that had to be silenced and nothing else. The ending itself presents the death of Koro-Sensei by the hand of his students, after they lost all their will to assassinate him. They put his life to an end the way he wanted, but they lost the best teacher they ever had.
In Assassination Classroom, Korosensei was aware of his eventual death and called it a cursed death. Being a former assassin who possessed Reaper attributes, he wanted to test his limits by turning against humanity and doing what pleases him.
Despite his somewhat sadistic nature, Karma actually has good values behind his motives, and can be quite empathetic. The reason he was placed in Class E was that he had rescued a senior from Class E being bullied by students from the main building. He is, unlike his former classmates, unprejudiced against Class E.
He was one of the most lovable characters in the series. The former assassin was a funny and loving character, which made everyone wonder why he would want to destroy the earth. Until one day, he told everyone about his past. The students decided to save their beloved sensei, however, it wasn't possible.
Aguri Yukimura is the deceased love interest of Koro-sensei in the anime and manga series Assassination Classroom. Aguri was the teacher of Class 3-E and the older sister of Akari Yukimura, better known as Kaede Kayano.
Goku's access to Instant Transmission means that no matter how fast Koro-sensei moves, Goku can keep up and eventually win.
Korosensei (real name Ryushi Korogane) is the homeroom teacher for Class 3-E of Kunugigaoka Junior High School, and the central character and main antihero of Assassination Classroom.
Summary. After the emotional assassination of Korosensei, Class 3-E attends the Kunugigaoka Junior High graduation ceremony to start their return to normal life. Seven years later most of the class reunite at the place where they hold treasured memories of their former teacher.
Kazunari Ninomiya: Koro-Sensei, The 'God of Death'
Karma is unquestionably the ace of the class. From his introduction, he's shown to be on a different level than everyone else, displayed to be a better fighter and stronger than everyone in the class. He's the third best marksman in the class, and the smartest of them all.
The melee duel starts and it becomes immediately clear that Nagisa lacks the strength to match Karma's. However he is able to hold his own. Both boys soon lose their knives, though Karma goes on the offensive as Nagisa tries to unsheathe his second blade.
Kaworu Nagisa is an anti-villainous antagonist in the Neon Genesis Evangelion franchise.
Karma never cried for anything or anyone before, the first time he cried was for Koro sensei. Kayano shut her eyes and silently cried as a tear or two slid down her cheeks. "The hardest thing is the last goodbye... especially if you didn't know it was the last one" Karma said with tears in his eyes.
One of Koro-sensei's major weaknesses happens to be water, but his body accounts for this by producing mucus that can lessen, or even negate, the swelling to his tentacles after they've made contact with even minuscule amounts of water.
He underwent a grotesque transformation because he felt that he was giving up his humanity and becoming a monster. Finally, his transformation to yellow occurred after he escaped in 140, underground. This lovable yellow form was because of his emotional change.
8 He Never Got The Chance To Become Human Again
Although Itona and Kaede were freed from the tentacles, others like Koro-Sensei and The Reaper who had undergone dramatic physical changes as a result of being injected with tentacle cells never got the chance to revert back to their human forms.
Koro-sensei's last words to him are those of pride and regret that he hadn't been more attentive, and promising that if they meet again, he'll treat him better.
The series includes images of students holding guns and trying to shoot their teacher, which has led to complaints from parents and teachers, as well as disputes over sexually explicit content involving underage characters.
After a total of seven years after Korosensei's assassination he became a student teacher at Paradise High School as the Homeroom Teacher of Class 3-5, a class that was disorderly and full of male delinquents.
