A/N: My first try for Assassination Classroom. Contains Spoiler, as I am starting after Chapter 147, so you have been warned. To clear all irritaions befor, I have placed the fight between Karma and Nagisa before Karma's birthday on purpose. And from here everything is mostly my on idea, so sorry if Koro-Seinsei or other Class members become too redundant. Most of the focus is on Karma/Nagisa and their feelings and Famaly matters(especially Karma's) and my OC that supports my Ship^^

So have fun reading and please tell me your honest thoughts about it (I do apologize for typing errors and grammar)

The school bell rang. Everyone in class E stopped their conversations to get to their seats. Ready to start the lesson as Koro-Sensei entered the room.

They were in the middle of the second semester, which flew by so fast, Nagisa couldn't actually believe it. Time sure passes fast, he thought, to think that Christmas wasn't far away anymore. However a lot has happened in the past months. All the attempts to kill their teacher, all the lessons they had, all the people they had met. Just a lot happened. To think about Kayano's real intentions to be in the class and the past of Koro-Sensei. By now everything was fine, Kayano being here, as her usual self.

It was nice for Nagisa as the blue haired let his sight go around, realizing how much the students grew up. Learning from their mistakes, seeing a good future in front of them. All of them have also changed, character wise and have matured. As his sight stopped by the redhead he thought, maybe not really.

But now he remembered their last fight. Back then when they argued, whether to kill Koro-Sensei or not, where the whole class was parted into two groups, no one accepting the opinion of the other. Especially Karma and Nagisa argued badly, turning this event into an elimination game. Two groups, blue as the save team and red as the assassination team. Being the last ones on the ground Karma turned the game into a one-on-one fight.

This one fight actually changed something in between them. Trying to make the other listen, they finally came to understand each other. By that time, they were friends, but didn't really feel like that. Considering the honorifics they used to call each other, even the class wondered if they were actually close. Also they learned to respect each other's opinion. And now the blue head is sitting here still not able to believe that he actually defeated that Karma.

Back then they did realize it. They were close friends. Best friends. It was nice to know that Karma finally felt like that too. After their fight, he said that he'd listen to Nagisa. It made him happy. After all Nagisa admired Karma for a long time, so obviously he was glad. Which brought a smile on Nagisa's lips. As he snapped out of his thought, he found Karma smiling back. Oh no thought the blue head and quickly turned around. Slightly blushing. Have I been staring the whole time?

But it was nice to have spent a lot of time with him. Planning assassination, going on trips, it was somehow strange seeing Karma so often. Since he came back from suspension, somehow there was that strange feeling inside of Nagisa, for a long while. What was that, Nagisa had no idea.

The class went by. Surprisingly without assassination attempts, not even from Karma. Nagisa packed his stuff in his beg and left. Just when he was about to leave the building a strong hand gripped from behind. He turned around to see the redhead. "Karma" "Jo" the boy replied. "Something against me accompany you?"

The blue haired boy shock his head, after all they always walk to the station together. Well, the time they were together, both of them were silent, maybe both felt unsure, because their fight wasn't even a week ago. Until Karma finally broke the silence "How're the wounds doing?" he asked not even looking at his friend in his usual calm voice. He remembered quit well, that he beat him up pretty badly. (With the intent to beat Nagisa up until he would be unconscious not to mention). But Nagisa could clearly hear the guilt out of his words. He smiled, "everything is fine, wasn't bad in first place." "Is that so?"

The blue head hesitated before asking Karma: "What about you?" Karma laughed at this, much to Nagisa's annoyance. "As if your fists even made a bruise." Feeling a bit offended the shorter boy sped up a little to let the other one slightly behind. "Not everyone is strong as you are."

"And not everyone is as weak as you are", Karma smirked back. By the time they had reached the train station, making Nagisa ready to say goodbye when Karma, this time seriously, asked him again: "Would you like to come to my house."

Nagisa didn't answer out of surprise, but thinking it over it had been a while since he met him at home. It was still surprising that the redhead asked him so suddenly. When the shorter one remained silent Karma continued: "It's been a long while since I had someone visit me." Karma's voice was lower than usual and the feeling of sadness could be heard. "Um… well… why not."

So instead of taking the train home, Nagisa found himself on the way to Karma's, of course after he informed his mother. As far as the blue haired remembered Karma lived in a huge mansion, somewhere a little outside the city, because of the job of his parents he was pretty rich. The last time Nagisa was there, he only saw some maids and one personal butler of Karma. His parents, however, made an excuse to tell that they wouldn't come in two or three month. So he ended up, being targeted by Karma's pranks, and believe it or not, this were times Nagisa had only nightmares of. Maybe that was the actual reason not to visit him again. The short boy thought.

"Yo, guys", a feminine voice took their attention. As the boys rose up their heads they looked at a young girl, black hair tied up in a ponytail, in designer cloths, who was looking back rather bored. "Hi Rin" Nagisa replied, while Karma just glared at her.

Rin happened to become a new student some time ago. She was introduced by Karasuma-Sensei as a pro assassin, (in that young age), who was also sent to kill Koro-Sensei. She seemed to be rather darker natured, judging from the glare she always gave everybody around her, but turned out to be somewhat nice, if not in the mood to mock others. She is the kind of person, who Nagisa would describe as direct and logic, saying what she thinks without even bothering about others feelings. But she is nice and very beautiful.

"What are you doing here, nasty woman", greeted the redhead, "none of your business wasabi bastard" she replied (obviously knowing Karma's obsession with wasabi…). That situation reminded the blue haired of how much these two actually disliked each other. Maybe it was because of the first comment Karma gave when Karasuma-Sensei told them, that she was a pro.

"Eh, so nowadays even stupid little girleys are called pros?" commented the red haired, mockingly while the girl in front was obviously pissed (not to mention the other ones) "Well then, what about showing me how a real pro is supposed to be", Rin replied, managing to stay calm. Karma knew her intension but jokingly pointed towards Nagisa. Rin, confused as she was, rose one eyebrow, making a face with a -Are-you-serious-expression.

"Who, that girl over there?" at this point everyone forced themselves to not laugh, while Karma broke into laughter. "I am a boy", said Nagisa ashamed of the situation. "How am I supposed to know", the black haired girl replied, again in a bored impression. Karma then stood up and led the way outside, waving with one hand to make a sign, to follow. As the two left, the rest of Class E followed quickly.

The two students stood in front of each other (Karma's a little bit bigger) while the boy was smirking the girl shot him a deadly sight. "Man the new girl is just awesome", Okajima commented, "even hotter when angry" "That's what you care about?", Nagisa asked little stunned.

Karasuma-Sensei sighed, not believing that this happened now, but then explained the rules, they must follow while fighting. "No real weapons are allowed, you will fight with the anti-Sensei knives. The first one managing to 'cut' the others neck, however wins." He gave the signal for them to start and as soon as the teacher stepped away Rin ran straight towards the redhead, pretty fast. Karma, however, hold the knife in front of him, near his chest, ready to block any attack. It was then, when the girl struck with her knife, obviously getting blocked. In the same moment Karma realized that she indeed was quite powerful for a girl, not as much as he was, but still making the alarm bells inside of him ring.

Rin backed up, not really going back but making flic-flops. While increasing the distance between them, there suddenly flew a little ball at Karma making him dodge, being panicked, when a knife just barely missed his open neck. "She indeed is good" he thought while grinning nervously, 'that one ball flew out of one leg of her jeans. She is prepared'. He caught back his balance now making his move. He just swung around his knife, which was easily dodged by the girl, but in return showed her reflexes and how flexible Rin was.

Karma decided to change to material arts going first with a kick, which was blocked with Rin's own leg, despite the difference in power. Their next steps reminded everyone else of the training with Karasuma-Sensei when he blocked all the attacks. Just in this case Rin's movements seemed gentler and smoother, but still being forced back. Even though that, it was clearly visible that material arts was her elementary though.

Well the rest of their fight was pretty impressive. Blocking each attack, making surprising moves. Nagisa had never seen Karma to have such a hard time in a fight. Which ended with both of them holding knives at their necks, totally exhausted, coming to a draw. Impressive. She indeed was good, after all who would have been able to fight equally to Kama, none of the class members though.

"So you two on a date or so?" she asked, still in her bored tone. "O-of course not", said Nagisa a little embarrassed, "Karma invited me to his home." The girl sat down next to Nagisa changing to a mocking smirk, and narrowing a little her greenish eyes, "for a romantic dinner?" "No!" Rin sighed and decided to be just quiet, whatever, she thought, I would love to help with the date. She started to smirk coming up with an idea. It happened that she, even though hating the redhead, liked the idea of them being a couple. Not to mention, that she was actually the first to realize how close their friendship was, even if these two didn't seem though, but after their fight, the boys had been best friends.

The only problem was how to get to Karma's house. If she asked to come along, obviously Karma would be suspicious. While thinking of something Nagisa pulled her out of thoughts. "Um… you know…" he began nervously, turning to Karma, "why not inviting her too?"

Both Karma and Rin widened their eyes, one disgusted while the other totally happy. You just made my day Nagisa!
