Work Text:
Nagisa was never very emotional, always calm and quiet. Especially around his mom, it stayed like that his whole life until he met his future boss when he was 8 years old.
His boss trained him to be the best assassin in Japan by the age of 9, by 10 he could take out a dozen men by himself and not ever flinch.
That all changed when he met Karma. Karma was the first person to ever talk to him, after all no one wanted to be friends with the emotionless weird kid. Nagisa really liked Karma as a friend but Karma wanted more. He knew Nagisa didn’t know what that felt like so he made it his mission to make him fall in love with him.
It worked that whole year Karma made it his mission to make Nagisa his boyfriend. He did succeed. It only took about two weeks. Karma thought it was going to take way longer than that but it didn’t. Eventually Karma got suspended and Nagisa got moved down to class E.
His second year Nagisa didn’t make any friends. The only time he felt anything was when the wind was on his face while waiting for a target. The only moment he truly cared about anything was when there was a target to be dealt with.
Nagisa did get his wish right before that year ended and agent of the ministry of defense came in to there classroom. He explained that he needed their help to assassinate this creature that wanted to teach there class. No one really knew why though, It is safe to say they were stunned.
The start of that year didn’t change much besides, no one talked to Nagisa much. That is until they all started training to be assassins, which Nagisa already did. After all he was the youngest and best assassin in Japan. It first started when Korosensei noticed how during training never partnered up with anyone unless forced to, Always kept to himself and never raised his hand in class. From that point forward Korosensei would randomly call on him and try to include him in class discussions. Soon he realized Nagisa was very intelligent he just didn’t show it. He was also very skilled in assassination techniques from what he saw during class 3- E ‘s training. Korosensei still didn’t really make any progress with Nagisa he still didn’t raise his hand or talk to any of his classmates voluntarily.
That was until Karma Akabane came into class. That first day Karma came late and the first time he saw Nagisa acknowledge anyone was when he saw him and Karma nod to each other. Nagisa still didn’t show any emotion in class or out. Eventually he had an idea, he was going to have the whole class do introductions.
The class didn’t mind they did it any way until they got to Nagisa witch of course he had a problem with it but couldn’t standout by not doing it, so he stood up and walked to the front of the class and said in the most monotone voice ever “ Hi you already know my name so why am I doing this?” He looked over at korosensei. He explained “ Well I thought this would be a good way for me to get to know you.” “ Unless you forgot you don’t talk much.” Nagisa sighed “ Fine Nagisa Shiota” “Happy?” He looked at korosensei “ That was good now say one fun fact about yourself that most people don’t know.” Nagisa rolled his eyes at that “ Whatever I guess….oh yeah I am the worlds youngest and best assassin in Japan Halo.” With that he went back to his seat. It was safe to say the class was shocked, the only person who wasn’t was Karma. He just started laughing the class looked over confused all he said was “ What don’t give me that look your faces are hilarious, and you Nagisa you can’t just go around telling people that it is not safe.” Nagisa turned around and said “ when was the last time you saw me give a damn?” The class was shocked one they never hear Nagisa talk unless absolutely necessary and even then it’s only one or two words. Nonetheless class continued and ended.
It was now lunch but only Nagisa left the whole class stayed to ask questions and talk. “ Soooooo any idea what that was about?” Kayano asked Karma was the only one that knew, they still didn’t even know how he knew but he did. Karma explained “ Yeah Nagisa is an assassin and a good one at that, he is very talented.” “ There is also a reason he doesn’t talk much, I will tell you if you give me 20 bucks.” The class was too curious, not too, so they gave him 20 bucks. “ Nagisa doesn’t have a great home relationship with his mom she puts a lot of pressure on him so he doesn’t get close to people so they don’t except anything from him.” The class now knew why he didn’t talk to anyone and didn’t like being around people. They felt bad but there was one question tugging at the back of their minds. Isogai finally asked “ How do you know this?” Karma simply answered “ He’s my boyfriend.”
Now the class wad really confused if they weren’t already. Everyone asked “ HOW?” Karma said “ I asked and he said yes.” It is at that moment the bell rang and according to Karasuma the new PE teacher was here. No one liked him they wanted Mr Karasuma back. Nagisa didn’t really care he just did what he was told that is until Takaoka came up to him and told him “ You know that is not the right way to hold a knife. Nagisa ignored him. He knew he wasn’t but obviously didn’t voice it. Takaoka tried to grabbed his arm to teach him how to act around authority figures, he was not prepared for what happened next. In .3 seconds Nagisa was behind him and holding the plastic knife to the man’s neck. All he said was “ Are you sure I am doing it wrong, maybe you just don’t know how and assassin hold their knife.” With that he walked away, Takaoka desperate to try and get back his dignity chased after him and tried to grab him. The whole class was watching at this point and they didn’t know what was going to happen. They watched as Nagisa seemed to vanish and appear right behind Takaoka this time with a real knife to his throat. He didn’t use it though he just ended up knocking him out. The class immediately surrounded him “ That was so cool “ “ did you learn how to do that in assassin training?” “ Can you teach us?” Nagisa was surprised he never got this much attention before, Mr Karasuma walked up and said I hope he didn’t cause you any trouble. Nagisa just shook his head. Karma translated “ That is Nagisa speak for no in fact he was easy to take down.” Nagisa nodded, everyone was shocked even Mr Karasuma.
They continued training, well not really after Karma explaining the fact that Nagisa is an assassin to Mr Karasuma he let Nagisa do what ever he wanted as long as it was productive. He ended up using that time in practice his sniper skills which he was very good at already but still wanted to work on. He ended up hitting all the targets while his classmates watched him do many different positions, from upside down to mid flip and even from 5 miles away he still hit it perfectly. Close to the end of class Mr Karasuma had a competition whoever could hit Nagisa in paint ball would get to leave early from class for the week, they were motivated but a little nervous after all he is a professional, they are just kids.
You can imagine how that went. With Nagisa taking about half of them out with his long distance sniper move and about 7 with a close range gun. That left 6 and he was going to get them. It was less then a minute when the 6 came out and tried to attack Nagisa gracefully dodged their attacks with a series of flips and rolls, while mid flip he hit 3 people and only 3 remained. They really tried but they were no match for Nagisa he beat them in close combat as well with a knife. The class sat defeated by one person. Some none of them knew very well, except Karma who sat out knowing how it would go. Nagisa nonchalantly walked up to them, and for the first time “ That was pretty good for your guises first time.” They were shocked he voluntarily talk to them for the first time ever. They started cheering and jumping, Nagisa looked at them confused. Karma explained “ They are cheering because you talked to them you dork.” Nagisa just shrugged and walked away. The class want to know where he was going but didn’t want to pry so they turned to Karma, who obviously knew where he was going. He signed and gave a signal for them to follow him. He brought them to this beautiful area where there was a small house built in the center. They knocked and Nagisa opened the door, he let them come in and they were amazed at the detail of the house. Karma explained again “ As I said before him and his mom don’t get along so he comes here when he doesn’t want to go home.” Nagisa nodded, Isogai asked Nagisa “ Does he always talk for you?” Nagisa nodded again and said “ I don’t really enjoy talking so he does.” That made a lot of sense now. They hung out in the little house for a while just trying to get to know each other better, with Karma doing most of the talking for Nagisa. Nagisa didn’t know how to describe this feeling it was like he was happy to have people in his life. He wasn’t sure if he was being completely honest with himself but that is what it felt like. Was he happy to have friends?! That was one answer he didn’t have the answer to.
