Darkness within [karmagisa]

Assassination

(A.N. this chapter contains hints of child abuse just a warning)

Karma [POV]

I don't think that Nagisa had ever used crutches before as he was very wobbly with them.  I didn't expect him to forgive me for kicking him but I didn't hear anything else from him though and simply sat down at my desk him doing the same.  He put his head on his desk laying on his arms.  He watched Korosensei listening to his lesson for a while.  I think he fell asleep by now and it was starting to get concerning how easily he's been falling asleep.  The thing is no one bothered him not even Korosensei.  By the time the bell had rung Nagisa was still sleeping.  He shifted in his desk knocking over his bag the contents spilling out as I walked by.  Nakamura and I were standing there.  Inside his bag were the normal things for school like notebooks and pencils though he also had a gun and two knives.  What really confused me though was that Nagisa had a bottle of some sort of pills, the label was scratched out.  Nagisa stirred and woke up seeing the bottle of pills in my hand

"Nagisa what are-" I didn't even get to finish my question before he snatched the bottle from my hands

"It's for fever I had them in there when I was sick once and never got around to taking them out" He laughed nervously gathering his things and stuffing them back into his bag.  Checking his phone he realized class had ended

"Oh see you tomorrow" he called swinging his bag over his shoulder using his crutches to hurry out of the room.  When he was gone and the door was shut behind him Nakamura spoke up

"Korosensei....., those pills..., they weren't for fever were they?" she asked

"If I could smell right they appeared to be a type of pain killer" He answered

"Nagisa really is weird" I muttered to myself shaking my head

*Time skip: Next morning at school*

Nagisa didn't seem like himself when he came in for school this morning.  He only had one crutch that he used to walk and he only tired his hair back in a ponytail just like he did in second year.  After class started I could see him looking at Korosensei periodically.  He picked at his bandages from under his desk.  After getting our work Nagisa worked on it for a while picking at his bandages until they came undone.  I saw his smile from behind his bangs looking at the bandages.  That psychotic smile.  He went up to Korosensei still only using one crutch.  From the back of the room I could barely hear his conversation

"Korosensei the bandages came undone could you help me?" He asked innocently

"Of course Nagisa" Korosensei pulled up a chair sitting him down looking at his ankle again

"Nagisa you need to be more careful now" He scolded re-wrapping the bandages.

"I know I know" Nagisa agreed, I saw something that Korosensei didn't though.  Nagisa pulled a knife from out of his pocket carefully while Korosensei was distracted.  In a quick movement Nagisa managed to cut off one of Korosensei's tentacles and slash his face before Korosensei jumped away all the way to the back of the room next to me.  By now everyone was looking at Nagisa.  There was that crazy look in his eyes and this psychotic smile.  The bloodlust radiating through the room  didn't feel like Nagisa, it felt like something more sinister.  Right then the bell rung for lunch.  Nagisa picked up the crutch that had fallen over using it to walk out of the room smiling at Korosensei before disappearing down the hallway.

"Karma what did you do to Nagisa" Terasaka accused

"What makes you think I did anything?" I argued

"You saw that and you know it yourself that wasn't something Nagisa would do" He shouted

"Karma that's something that you would do" Nakamura agreed and now everyone was looking at me
