Heyo!

So I have no idea where this idea came from but I felt like it needed to be written.

Summary: What if Nagisa and Karma got together before the manga started? Bamf! Karma because why not and (probably) some mind-numbing fluff later. (Really slow updates. Just warning you now).

Pairings: KarmaxNagisa

Warnings: unedited, unbeta'd but I'm pretty sure I didn't swear. For once.

Disclaimer: No, I don't own Assassination Classroom, but name your price.

Enjoy!

"Yo, Nagisa"

"Karma-kun! You're back!"

Karma smirked and hopped down the steps before kissing Nagisa on the cheek. "Still adding 'kun' onto my name, Nagisa? And here I though we had moved past all that."

Nagisa blushed and buried his face in Karma's chest.

"That's the infamous Koro-sensei, huh? I thought he was supposed to be yellow," Karma remarked curiously, snaking an arm around Nagisa's middle.

Nagisa turned around to look at Koro-sensei in confusion. "He is yell…" he trailed off.

Koro-sensei was pink.

"Koro-sensei's face changes colour depending on his emotions," Nagisa sighed, "it's usually yellow."

Karma nodded and let go of Nagisa. He walked up to Koro-sensei and held out his hand with a smile.

"Nice to meet you, Octopus-sensei," He greeted, but as soon as Koro-sensei placed a tentacle in his hand, it exploded.

"Heeh, so these things really do work," Karma mused, turning his palm up to face Koro-sensei.

Taped to his hand was several strips of green anti-sensei matierial.

"What's the matter? Too be fooled by such a simple trick, and jump all the way over there… are you a scaredy-cat?" he mocked.

If the class wasn't shocked before, they were now.

"I heard you're called 'Korosensei' because you're unkillable," he continued, advancing slowly, "but what's this? Sensei, could it be that you're actually an easy mark?"

Veins popped in Korosensei's head and he twitched with agitation. His eyes narrowed and his permanent smile grew thinner. He was really pissed off.

Smirking, Karma walked back to Nagisa, who was staring at him in awe.

"You're the first one to hurt Koro-sensei!" he congratulated.

"I am? Wow you guys must be worse than I thought."

"K-Karma-kun," Nagisa stuttered.

"Hey, Nagisa came pretty close once!" Okuda piped up.

Karma turned to look at her, raising an eyebrow. "He did?"

"Yeah!" she nodded, "He had a grenade full of anti-sensei bbs tied around his neck and he went up to… sensei and… why are you shaking your head Nagisa-kun?"

"E-eh? I just don't think it's a very interesting story to tell i-is all," the blue-haired boy stammered, trying to end the conversation.

"No, please continue," Karma instructed, a sickly sweet smile painted across his lips.

"W-well Terasaka exploded the grenade when Nagisa was close enough… and… yeah.." Okuda finished lamely.

Why wasn't I told about this?! Karma fumed silently, he could have gotten hurt - goddamnit Nagisa, do you have no sense of self-preservation?

"Which one is Terasaka?" he inquired all too innocently.

Kurahashi and Nagisa shared a nervous look.

"I'm Terasaka, are you the new kid?" A gruff voice sounded behind them.

Karma whirled around and pressed his hand against the taller boy's throat. "If you ever lay a hand on Nagisa again, I will kill you," he promised, glaring at him.

Terasaka gulped. "B-but the prize money would have covered the cost of the medical bill," he nervously tried to justify.

"That's not the point," Karma growled dangerously, tightening his grip, "it's the fact that you would have put him in the hospital that I'm talking about."

Nagisa sighed and walked up the them, placing a hand of his boyfriend's shoulder. "Karma, it's fine," he urged, turning the red-haired boy around to face him, "I'm completely fine."

Karma let go of Terasaka's throat and wrapped his arms around Nagisa, resting his head warily on his shoulder.

"Why can't you give my heart a rest for a change?" he sighed, "first it was the bullies, then it was her… and we still haven't solved that one!"

"I-I'm sorry," Nagisa apologised.

Karma drew in a deep breath and raised his head. "Don't worry about it, tiny person," he remarked cheekily, "I'll just have to kill that octopus before you can endanger yourself further."

A blush crept up Nagisa's neck as the rest of the class looked on curiously.

"Hey Nagisa," Kayano started, "It hasn't been that long since I joined class E, so I don't know him."

"He's a total dork," he deadpanned.

"Hey!" Karma protested, playfully pulling his boyfriend into a headlock, "I got suspended for violence and stuff. I am the biggest badass you've ever seen."

"You're a dork," Nagisa sang, twisting out of the hold and poking his tongue out, "and you like annoying people, that's why you're here."

"Keep telling yourself that."

"If you two keep going at it like that I'm gonna be sick," Yoshida scowled, "who cares if we got some new hot-shot in this class?"

Nagisa put his hand up.

Kayano giggled.

"Well you asked," nagisa reasoned.

Karasuma-sensei clapped his hands to get the class' attention. "Just because we have a new student, doesn't mean we get off-track," he announced, "Karma-kun, you were late. It's your first day, so I'll let it slide this once, but don't expect the same every time."

"Dually noted," Karma promised, smirking.

"Get in a line and try to hit me, you can attack with more than one person if you like," Karasuma-sensei instructed, getting into a defensive position.

Sugino went first, haphazardly swinging the dagger in the general direction of their teacher. He was flipped over and had a green blade to his throat within seconds. He shrugged and somewhat dejectedly joined the end of the line.

Korosensei sipped his tea next to an impressive sand sculpture he had constructed within seconds.

Suddenly, a grenade flew through the air and buried itself at the foot of the sand-temple and detonated, hundreds of anti-sensei bb's rocketing out from the small explosion.

Korosensei appeared on the other side of the line of students, wailing about his magnificent work of art.

"Eeh? what would you know?" Karma smirked, throwing a second grenade up in the air and catching it, "these things really are useful."

Terasaka's eyes widened as he realised who it belonged to. "How did you-" he gasped furiously, hands flying to his pockets where the grenade was previously kept.

"You really should pay more attention to you surroundings," Karma mocked gleefully.

Nagisa rolled his eyes. "That fell out of his pocket and we both know it," he remarked cheekily.

"Shush you," the taller boy murmured, pecking him on the cheek.

"Karma-kun…" Korosensei fumed, "I worked hard on that!"

Karma turned towards him and smirked. "I know," he admitted simply, "but it doesn't matter, because this is only the beginning. I will teach you what it means to be killed."
