Hey guys :D so I recently watched this series and fell in love with it and I really liked the idea of writing a future story involving Nagisa and Karma because, let's face it, they're both totally in love with each other haha anyway hope you enjoy, for the smutty stuff turn to chapter 8 (you're welcome) and sorry if there are any mistakes I've missed in this one, it's like half 6 where I am. Enjoy 3

I knock cautiously on the door of Karasuma's office. It's been a while since I've seen or heard from him and I'm wondering what on earth was so urgent that he calls me up and tells me to come as soon as I'm finished at school. I wait. If he's not in I'm going to be pissed after all that urgency. After a minute or two I hear a gruff 'enter' and I push the door open.

Karasuma is sitting behind his desk looking the same as ever; his hair neatly cropped, his suit wrinkle free and his eyes as cold and focused as I've ever seen them. Whatever he has called me for it isn't to play catch up. I make my way over to his desk, after closing the door behind me, and giving him a quick bow.

"You wanted to see me Sir?" I ask. It feels like I'm back in Junior High again and have been sent to his office because I'm in trouble. He doesn't seem to notice this.

"Have a seat," he says nodding to the chair in front of his desk. I sit down but more perching on the edge than actually making myself comfortable. "I'm sure you're wondering why I called you here this evening."

"A little," I admit. "You sounded so insistent on the phone."

"I called you here this evening because I have a job for you," he says.

"What kind of job?" I ask after a pause. I know exactly what kind of job, I just want to hear him say it.

"An assassination job," he replies, "I have a target I need you to take care of." And there it is.

My name is Nagisa Shiota. By day I'm your usual under-paid, over-worked teacher but by night I am an assassin. I'm one of the best in the business, my first kill being at fifteen, and there is no one I can't take out. People call me The Viper because I'm silent, calculated, deadly and you won't know what's hit you until it's too late.

"It's been a while since you've asked me to take someone out," I say. "Your new recruits not up to scratch?"

"You'll see why it has to be you when you see the target," he tells me.

Now I'm intrigued. Someone who only I can kill... that hasn't happened in a while either. Karasuma tends to call me in only as a last resort these days as he knows that I'm a teacher, first and foremost, but this is new. This is different. This is a target that might not be such an easy kill, I may have to work for this one.

"I know you don't like to be away from your students for too long so we will do everything we can to help this assignment run as quickly and smoothly as possible," he says.

"So who's the target?" I asked. His building suspense techniques are starting to wear thin and I just want to know so I can get out of here and get planning if this target is going to be as difficult to kill as he says. I doubt it's going to be another Korosensei so I'm sure I'll be fine on that front. No more targets that can break the sound barrier and are impervious to everything, thank you very much.

Karasuma stands and hands me a blue folder. I take it from him. It feels oddly heavy for a such a thin folder. Without saying anything to him I open it out on my lap to see the face of my target and I stop, my entire body frozen in place for second.

Staring back at me, looking exactly how I remembered him the last time I saw him at the end of High School, was Karma Akabane.

My head starts to spin and I don't feel as if I can get enough air into my lungs. Karasuma can't seriously want me to take out Karma, can he? Judging by the fact that he hasn't told me he's made a mistake and given me another, identical folder I would say that he probably does. I don't think I can handle this.

"What?"

"Turns out Karma has been making quite the name for himself over the last few years," Karasuma said, "and the government has deemed him 'unsafe' and he needs to be taken out."

"But why though?" I ask, still trying to wrap my head around Karma being my target. What could he have done that would warrant the government needing to have him killed?

"We have reason to believe the company he works for has connections to organisations with weapons of mass destruction," Karasuma says, "along with a group of scientists who think they can remake the tentacle formula."

"So shut down the company," I say. I don't know how I'm supposed to feel about this but all I know if that I can't even begin to think about killing Karma right now.

"It's not that simple Nagisa," Karasuma says and that feeling, as if I'm just a kid in Junior High again begins creeping back.

"Why isn't it?" I ask.

"Karma is a very persuasive individual, you know this," Karasuma says. "If he is allowed to continue in the position he is currently in then we could end up with a full scale international disaster on our hands. It has to be done, my hands are tied on this one, sorry."

"Okay," I say calmly. I close the folder and place it on the edge of his desk. "Then find someone else to do it."

"What?"

"Find someone else to take out Karma," I say.

"Nagisa this has to be you," he says.

"I don't kill people I know," I say and there is a definite edge to my voice. He can't seriously have forgotten why that is my one and only rule. His expression remains neutral so I decide to enlighten him. "The first one was hard enough."

"And I'm sorry that I'm the one to be putting you through this again, Nagisa, but for this to have even the slightest chance of working then it has to be you who kills him," he says.

"But why though?" I ask after a pause.

"Karma was part of the Assassination Classroom," Karasuma says. "He knows the tricks of the trade, anyone else he'll see coming a mile away. He's too much for the rookies and he knows the profiles of anyone else I could send to do the job. You he won't suspect."

"Karma and I haven't seen or spoken to each other since High School," I say. "He's going to be suspicious if I suddenly turn up after fifteen years without warning."

"Oh..." Karasuma says and finally shows some emotion (seriously, how does Professor Bitch deal with this guy being so cold all the time?) as he seems surprised to hear that Karma and I became estranged. "I would have thought that you and Karma, of all people, would still be in regular contact with each other, given how close the two of you were. What happened?"

"We had our reasons," I say. I could hardly tell Karasuma the real reason why Karma and I lost touch with each other.

On the anniversary of Korosensei's death, before the both of us left for university, Karma and I went up to the mountains and our old Junior High classroom to drink. We both drank more than we intended to and, without thinking, I kissed him. I'd been waiting to do it for years and alcohol finally granted me the courage. He kissed me back, things got heated and I lost my virginity to him up against the old sports equipment shed. We had fallen asleep in each others arms and, when I awoke the next morning I was hung-over and couldn't face Karma telling me that the night before had been a mistake so I pulled on the rest of my clothes and ran. I ignored his phone calls and texts and eventually he stopped calling.

Seeing him again now, after all these years, is going to be weird...

"Well hopefully, if the set up we have goes to plan, then it won't look suspicious when you suddenly reappear again," Karasuma says. I say nothing, I don't agree but whatever. "We have it on good authority that Karma is going to be hiring a new personal assistant so we can use that as our window to get you in."

"Hang on wait, you want me to take time off work for this?" I ask. He can't be serious! I have classes and students and I can't just walk away from that for however long he predicts this will take.

"Yes," he says matter-of-factly. "I took the liberty of speaking to the principal of your school. I have requested cover for you while you take a leave of absence for personal matters that I did not disclose."

"I haven't agreed to this," I say, "please don't make these decisions for me."

"The reward for doing this is lucrative," Karasuma says, as if he can bribe me with money. He should know me better than that by now. "It should more that cover the weeks you miss teaching."

"You're still asking me to kill one of my old friends," I say. "It is not going to be as easy to win me round to the idea as you seem to think."

"Nagisa I'm sorry that I have to do this to you again but we need you," he says, imploring me.

I stop and think for a moment. Could I do it? When it actually comes to the moment where I have a gun in my hand or a knife at his throat can I actually bring myself to do it? I did it once before, I suppose, but when I killed Korosensei I had the rest of my class rallying around me (including Korosensei). This time I'm going to have to be the one to pick up my own broken pieces when all is said and done. On the other hand Karasuma is relentless in his persuasion; he will stop at nothing until I agree.

I sigh. I really am backed into a corner on this one and I guess he has already covered my class for me... and I guess it would be nice to see Karma again (hopefully he will have forgotten about my hitting it and quitting it).

"Fine," I say. "I'll do my best."

"That's all I ask for," Karasuma replies and I just give him a tight lipped smile.

My name is Nagisa Shiota. By day I'm your usual under-paid, over-worked teacher but by night I am an assassin. I'm one of the best in the business and there is no one I can't take out. My new target, my old best friend; Karma Akabane...
