Karma was pissed.

He had come so close so many times, but now the octopus was getting used to his attacks.

"No matter what I do, I end up with this number," Korosensei announced, then turned his back and raised the chalk to the board, "you are plagued by such worries of invisibility!"

Now, he thought, pulling out a gun from under his desk.

Before he even realised what was happening, the gun was out of his hand and his nails had been painted with shiny love hearts.

Karma glared at the obnoxiously yellow teacher as he turned back to the board, chalk tapping rhythmically as he showed the class how to work out the problem.

Just you wait, Karma thought venomously, I will kill you.

4th period was Home Economics.

Home Economics was ok. He could work with that.

"The taste is kinda sharp.." Fuwa mused, taking a sip of the soup.

"Then how about remaking it?" Karma interjected, before grabbing the handle of the pan and tossing the boiling contents all over Korosensei.

Blade out, in position, find where he is and….

He was wearing an apron.

He could hear the class giggle around him as Karma immediately pulled the infernal rag off his hair.

Blushing slightly, his glaze landed on Nagisa, who smiled apologetically at him. Karma knew that his boyfriend was trying to think of a weakness that could help in this situation, but he had already realised that while the alien-like teacher might make many blunders and slip up easily…

The knife in my sleeve…. now!

… his surprise attacks wouldn't work anymore.

Eyes wide, Karma gaped at Korosensei as a tentacle combed his hair down while another sprayed something in it, one still remaining on his forehead.

Now he was really pissed.

Karma sat on an overhanging tree, biting his nails in frustration. How can I kill him…. he thought, what haven't I tried yet… how can I kill him…

There was a rustling behind him. "Karma-kun," Nagisa's voice sounded from behind him, "don't be impatient and we'll kill him together."

It was almost laughable, how easily those words flowed out of Nagisa's mouth. Karma remembered when the small, blue-haired boy would splutter incoherently that yes it's a bad idea! whenever he talked about anything related to violence.

He took his fingers out of his mouth and stood up, turning around so he could face Nagisa.

"If you target Korosensei alone, you won't be able to kill him," his boyfriend beseeched, stepping towards him and taking his hand, "no matter how many tricks you use."

Karma leant down and pressed their foreheads together, smirking slightly at Nagisa's blush. "You know how it was like with that teacher…. I want to kill him," he murmured, "that octopus surviving by some fluke would piss me off the most."

Nagisa sighed and drew the red-haired boy into an embrace. "Doesn't mean we can't work together, you know," he whispered into his neck, sending shivers down Karma's spine.

"Oh no, I seem to have interrupted a moment."

The pair jerked apart at the voice and Nagisa glanced at his boyfriend worriedly.

"Today sensei provided you with a lot of improvements," the teacher told him smugly, green lines appearing on his face, "you can still come and kill me you know?"

Karma scowled, then relaxed. He smiled.

Dread slipped down Nagisa's neck.

"I'd like to confirm it, but you're just a teacher, right?" the taller boy asked in faux curiosity, moving away from his boyfriend, who tried to cling onto his shirt and walked up to the overhanging tree.

"So would a teacher," he continued, glancing at Nagisa apologetically, "put his life on the line to protect his students?"

Karma stood up, balancing precariously on the overhanging tree.

"Of course," Korosensei replied easily, "a teacher's a teacher after all."

The red-haired boy smirked, and Nagisa felt a burning desire to get him away from the edge. "That's good," Karma sighed, leaning slowly over to one side, "I can definitively kill you now."

To Nagisa, everything went in slow motion. His boyfriend slowly sliding his weight off the wood, arm outstretched and gun in hand, Korosensei standing still - why aren't you saving him - and the scream that tore itself from Nagisa's throat as he got to his feet and ran to the edge.

He saw Karma, smiling as usual, falling slowly, slowly, slowly, towards the ground. It wasn't slow enough. Nagisa studied his boyfriend's form with wide eyes like it was the last he'd ever get to see him in one piece.

(He didn't want to think about how true that statement could be)

The seconds were years and all Nagisa could think was Karma was falling Karma was dying why isn't Korosensei doing anything.

"If I save him he'll shoot me but if I let him die my existence as a teacher will be destroyed, huh?" Korosensei muttered, "yes, that's definitely what he's thinking."

Suddenly, Nagisa's gaze sharpened. He knew what he had to do and how to do it. He was going to save Karma.

Without warning, he darted towards his immortal teacher, green knife in hand, and slashed out in front of him wildly.

Korosensei, of course, dodged.

"You'll have to do better than that Nagisa-kun," he taunted.

Then Nagisa pulled out a gun.

It was an unexpected move, and it worked. With speed and fluidity he didn't know he had, he took the gun out from his waistcoat and pulled the trigger. There was a squelch and one of Korosensei's tentacles flew off.

"Save him."

Somewhere in his rational mind, Nagisa knew that the last thing his teacher would do is let Karma fall, but the rest of him wasn't listening to the rational side of things.

Korosensei blanched, but tried to play it off. "Of course," he chuckled somewhat nervously, "a teacher would never let his students die."

All Nagisa could see was blue hair as the teacher took off at mach. 20 speed, racing down the cliff. The blue-haired boy ran to the edge and looked down, heartbeat roaring in his ears. He swallowed wetly and something in his chest lurched.

Please, please be okay.

Karma was caught in a web of yellow tentacles, and Nagisa sighed in relief. He could see they were talking but all he could think about was what did I just do? How did I do that?

Within seconds, both teacher and student were safely back on the high cliff. Nagisa stayed where he was, arms shaking slightly and fists clenched in the dirt.

"Karma-kun, you acted so recklessly without batting an eye," he managed to blurt out, only just managing to hide the tremor in his voice.

"Not really," Karma sighed, "I thought it over and just figured it would be the best way to kill him… Guess I'll have to rethink my plans."

"You're not giving up yet are you, Karma-kun?" Korosensei sneered, "I still have a lot of maintenance to do."

Karma scowled. Stupid octopus, you shouldn't get so cocky, he thought.

"I will kill you," he told the teacher, "tomorrow, that is."

Korosensei's grin widened. "Ah, what a healthy and refreshing killing intent that is," he sighed happily, before blasting off into the sky.

Karma's hand dropped to his side and he turned to look at Nagisa, who avoided his gaze. Guilt shot through him like a bullet and he moved to hug the smaller boy from behind.

"You're mad, aren't you?" he murmured.

Nagisa nodded. "Why did you do that without any warning? You could have died Karma!" he exclaimed, turning in the red-haired boy's grip to face him.

"You were falling to your death and there was nothing I could do about it!"

Karma winced. "I'm sorry," he said solemnly.

Sighing, Nagisa rested his head on Karma's shoulder. "I hate you," he mumbled, "always doing stupid things that scare me."

"I wouldn't be me if I didn't," he replied softly, tightening his grip, "and you know you love me."

"I do. That's why I don't want you to die."

Something akin to cotton balls bubbled up in Karma's chest at the immediate response. He put one finger under Nagisa's chin and tilted his head up.

"I love you too," he smiled, "that's why I won't die."

"Good."

Nagisa pecked him on the lips briefly and smiled.

"Hey Nagisa, wanna go out?" Karma asked, smirking and pulling away, "I nicked the octopus' purse from his office so it's on me."

Nagisa smiled and rolled his eyes. "Korosensei isn't going to be very happy when he finds out y'know," he giggled, joining their hands.

"Then he shouldn't make it so easy to steal!" Karma reasoned as they made their way down the mountain.

I know, the 'I love you' was fucking cheesy but I couldn't help myself.

Please tell me what you thought, any mistakes I made or what chapter I should do next!
