At first you had been in the main campus at Kunugigaoka school. A prestige school led by a.. seemingly scary principal. He was terrifying. Then after that you had been kicked down to Class 3-E for being a troublesome student, a seemingly normal class but with a hidden secret, they had to kill a genetically modified experiment named Koro, who was your Sensei. Now you were a part of this too. Not like you minded just had to keep this a secret from the students at the main campus, which isn't easy because they look down on the students of Class 3-E. You got along with pretty much everyone after all it was important if you wanted to kill Koro-sensei before a certain date when he will destroy the earth. The one you got along with the most was Karma Akabane. The red head devil. He's pretty strong even back at the main campus he beat up students. Which is why he got kicked down to Class 3-E. Having a devilish mind like his, you pulled pranks with him, were scarily smart when it came to messing around and coming up with assassination attempts. Usually you two were the defenders of your class, when the students from the main campus had the audacity to annoy you or anyone else in your class. Having violent tendencies and all. Coming back one day, going up the hill where your rundown campus building was. To say you were a "bit" battered up was an understatement. When you entered the classroom, Karma walked up to you his eyes closed as he spoke. "Yo, you're here. Ready to do this-?" Karma opened his eyes, cutting himself when he noticed the state you're in and his eyes just darkened. "Who did this?" There it was, his protectiveness over his classmates. Especially you, since you were the closest to him. Karma isn't stupid, he knows it must have been someone from the main campus that did this to you. He just needed to figure out who it was and give them hell. Karma can only hope that you at least defended yourself against them as best as you could, even if you were alone.
