Karma Akabane

Summary

A student called Karma Akabane is shown all of the information of Koro-Sensei, because he will also be a student in class 3-E, just that he was suspended for a while. He shows up to his first day to school late, giving him a bad way to see him, but he shows he is a very good student and is very smart. When he goes and meets Koro-Sensei, he is the first human to actually damage him, only by giving him his hand (he sticks in his hand pieces of the knives that can kill Koro-Sensei). He proves other students he is the best in the class, an possibly the one responsible for Koro-Sensei's death in a distant future. Like I said before, he was a very good student, he was an A student actually, but the problem is that he is very very agressive, to the point he had to be suspended, so even though he had good grades they had no other choice that to put him in Class 3-E. After Koro-Sensei realizes he made a huge mistake by letting his guard down while meeting Karma, he shows him he is not easy to kill, and embarasses Karma in front of all of his classmates.
