This is set in an au where Karma doesn't hold back against Nagisa in the red vs blue arc. Also, Nagisa pulls out a real knife instead of a fake one. About the backlash he receives after this. Did sprinkle in some Karasuma fatherly moments to Karma and Sugino-Nagisa friendship but whatever. I don't actually want to write the fic of the fight, because I do martial arts and fights are a lot faster than reading speed.
The E-class is quieter than usual. A once bustling atmosphere is filled only by whispers. Until it goes silence at the sight of the cause of disruption of peace.
Karma walks into class, eyes empty and unfocused. He plops down into his seat and sits, motionless, staring blankly at his desk.
Sugino approaches him, angry over Nagisa's injuries due to Karma. He snaps at him. "Why do you have to be such an asshole? You broke Nagisa's fucking arm and gave him a concussion!"
Karma continues staring at the table. "I had to." Sugino shouts "no you didn't!" Karma looks up at him with crazed eyes. "I did... I... had to, he gave me no choice. I didn't want to fight him, but if I didn't he'd kill me, so I had to. I couldn't risk it."
"You hurt him." Sugino states.
Karma snaps, shouting with shaky hands. "So what! You just hate that I hurt your precious Nagisa! But you would've let him hurt me... You all just hate me! You think I'm a monster." His eyes flash with anger and he snaps his head up.
"I didn't want this! But it doesn't matter, you guys hated me before, so of course you hate me now! You all exclude and fear me based off rumours you know nothing about. You hate me and critisise my every move, my every breath. And you still aren't happy. I hear the things you all say behind my back."
Karma pauses for a moment before continuing. "You all think you are different from the main building, but you are just like them, you're just as exclusive."
"And you didn't deserve a one day suspension, you need to be expelled." Sugino replies.
"You think I should be expelled for defending myself? Nagisa was just as bad as me; he tried to stunt clap me, he pulled out a real knife on me! Have you seen what he did to Takaoka-sensei? He killed him not once, but twice and drove him to insanity. All I ever hear you talk about is how 'evil' and 'sadistic' I am, but that isn't all I am! It's just all you hypocrites care about," Karma finishes.
He pauses to look down at his table then back up at Sugino. Karma stands up, grabs Sugino by the collar and says "I don't know what your fucking problem with me is, but I'm tired of it. Grow up and move on. I haven't done anything to you!"
He throws Sugino back and walks out of the classroom, past Karasuma standing in the doorway, into the staffroom and sits on the couch, delfated.
"Maybe they're right. Maybe I am a monster. The only thing I'm good at is hurting people." Karma puts his head in his hands.
Karasuma walks in. He sits down next to Karma and rubs at his back, consoling him. Karma lifts his head, disgusted and about to snap until he realizes who it is. His shoulders drop and he leans back against the couch, looking up at the ceiling.
"Why do they all hate me? Nagisa is distant, Sugino has some kind of grudge against me, I'm too 'inappropriate' for Okuda, too mean for Terasaka, too much of a buzz kill for Rio and a freak to everyone else."
Karma looks at Karasuma too softly for Karasuma's liking. Karasuma's brow furrows.
"They're afraid of you. You don't have a very good reputation and your fight with Grip scared them. They don't realize the impact on you because they don't understand you. You are very closed off, Karma. You didn't let Nagisa in and you've taken a while to let me in."
Karma looks down at his hands in his lap. "Who says I let you in."
Karasuma's hand moves to Karma's shoulder, bringing him closer. Although Karma stiffens, he doesn't lean away. "If I were anyone else, including Koro-sensei whom you also admire, you would've sent me away. But you've let me stay."
"Look, you don't want to be alone, you're afraid of what will happen if you're not. But closing yourself off won't get you many friends. I would say you should apologize to Nagisa, and ask to be his friend."
Karma opens his mouth to say something but stops when he sees Karasuma glare at him. "Ask to sit with him and his friends, and to hang out with them this weekend."
"But, what if they say no?" Karma asks. "Then I will talk to them or you could try talking to Terasaka, or Isogai even." Karasuma replies.
Karma sighs. "Do I have to-" "Yes." Karasuma states firmly. "Ugh, fine." Karma groans.
Karma gets up and stomps to the door. He rounds the corner to walk back to class but is stopped by Nagisa dragging around a defeated Sugino. Nagisa has a fake smile on his face that can only mean business.
Nagisa drops Sugino's collar. Sugino rubs at his neck and sighs. "I'm sorry I judged you. I didn't realize you were upset what we did." Sugino says.
Karma pushes Sugino to the side. "Nagisa, I'm sorry that I concussed you and broke your arm, I felt I had no other choice. I'm actually sorry about a lot now that I think about it. Like cutting you off and not telling you why, putting you in a skirt an-" Sugino cuts off Karma by putting a hand on his shoulder.
Nagisa thanks Sugino, then talks. "I'm sorry for attacking you with a real knife and scaring you. But why did you cut me off and never talk to me again?"
Karma looks at the floor. "You poked me in the back one time at a restaurant and I thought you were going to kill me." Karma laughs, trying (and failing) to lighten the mood. "I was... scared so I left. I didn't want you to hurt me. I'm sorry"
Nagisa pauses, then speaks. "It's fine. Just don't do it again. Also, you can come sit with us at lunch, you probably don't like sitting at that tree in the forest all by yourself."
Karma smiles. "I don't mind it, it's a nice spot. But I'll move if you want me to so bad. Besides, how else will I tease you and Kayano?" He walks off back to class, shoving his hands in his pockets and visibly relaxing, a lazy smirk coming to his face.
And so everything is set. Karma is introduced to friends, drama is solved, the class' resolve is strengthened, and although it's a hard thing to do, the class knows they will kill Koro-sensei, and save the world.
