Chapter 1 - Civil War

Two boys stood on other sides of a small clearing on their mountain, surrounded by their classmates and teachers, all watching the unfolding match with either excited or anxious faces.

A soft wind breezed across the clearing, tousling their hair and cooling their heated skins. The pervious fights had left excitement pumping in their veins and now was begging them to continue and move. Fight and win.

Kill or Save.

Continue with the status-quo or start a new route.

The air crackled with tension and two pairs of eyes widened in nervousness and excitement.

The one they had been tasked with assassinating almost a year ago was standing between them, the usual grin on his face. Yet they ignored him, staring at each other, gauging each other's strengths and weaknessess, the adrenaline beating in their ears.

Although that should be a sad thing. They had known each other for so long they know most of the other's quirks, laughed and joked, enjoyed the other's company. They know a lot about the other and this year taught them even more. Much more than they had ever imagined.

But now... they don't know the other. Why won't the other understand their point?

How sad that the fight is something they felt was long due?

Two ideas. Two wishes. Two futures.

They can save their teacher, the one who gave them so much. They can perhaps remove the danger of the destruction, they have to save Koro-sensei. Give back even a little of what they recieved from the funny, ridiculous, perverted, gulliable yet warm, understanding, outstanding, amazing teacher.

They must assassinate their teacher. This is what their relationship was built on this entire year and just cutting it off by ridiculous claims of salvation? This is trampling over what they had with their teacher. Koro-sensei deserves an assassination worthy of its name.

It appears that they'll have to beat their reasons into the other. They'll have to make their point of view clear...

"I'll save him!" "I'll kill him!"

Shiota Nagisa, a boy with long blue hair pulled up to pigtails and wide blue eyes - the leader of blue team calling to save Koro-sensei and Akabane Karma, a redhead with piercing gold eyes - the leader of red team calling to continue the assassination locked knives.

They locked eyes, each seeing the determination and anger reflected in the other's gaze.

The first attacker will be—

Karma kicked Nagisa in the stomach, sending him to the floor and scattering leaves everywhere. The blunet coughed some leaves out, jumped and landed on his legs, arms in the defensive.

Karma noticed the extra knife Nagisa strapped to his leg and charged straight ahead, slashing at Nagisa. Nagisa evaded twice and thrust his knife at Karma's head, who ducked.

They jumped back, creating a small distance which Nagisa crossed over immediately and they locked knives once again, the blue paint flying over from the blunet's knife, nearly touching Karma's alerted face.

"Tch." I need to be more careful of the knife.

The redhead kicked immediately. The smaller boy held his crossed arms up in front of his face, but the leg didn't reach him so Karma span on one leg and thrust his foot into Nagisa's chest, this time successfully sending him crashing to the floor.

Nagisa sprawled on the floor, the air knocked out of him, but he didn't have a second to gain back his senses since he glanced up and had to roll right away from a stab attack. He looked back and saw Karma's knife stuck in the earth.

A chance.

NOW! He planted his hand on the ground and swirled around, knocking the knife out of Karma's hand, throwing it away. The taller teen looked at the flying knife and clicked his tongue in alarm.

An opening.

Here is my chance! Nagisa charged at the redhead, knife slashing only for a forehead to crash into his, causing the knife to fly away from his palm and for his hands to go up for his bruised forehead as pain flared up there.

The redhead smirked, Naive.

They stood up, sweat dripping from their chins; blue eyes wide with surprise and alarm, and gold eyes cautious. Their heartbeats were loud in their ears and in the bruised foreheads.

While still holding his forehead, Nagisa's free hand went for his second knife, slightly clammy from nerves.

He had to win this.

He had to use this.

Karma knew what the blunet was trying to do, though and he won't let that happen. Not so easily. In a flash, he was in front of Nagisa, elbowing him in the face. Nagisa staggered back, yelping in pain and blood bursting from his nose, but Karma wasn't finished.

"You won't be drawing that knife," Karma stated, arm going from bent to straight and hand from flexed to grabbing. Nagisa won't be allowed one moment of rest. One hand gripped and yanked at the blue hair while the other grabbed a bony shoulder, his knee going up to the blunet's stomach.

Nagisa gasped and gagged, going limp. Soft face looked up in pain, causing him to smile in victory, but then blue eyes, one half-closed by a bruise, narrowed and a punch hit Karma square in the face. Gold eyes widened as he felt a white-hot pain blossom from what could possibly be cracked nose-bridge and his eyes burned from the possible forming bruise.

He then forced himself to chuckle, ignoring the pain and the dripping crimson. Nagisa was much stronger than before. "Is that all?" He taunted.

He saw blue eyes flash with anger but Karma simply slapped his face firmly. Nagisa fell, but then used Karma's hold on his shoulder to hoist himself in the air and gave Karma a blow to his nape with both of his feet. Karma grunted as blood trickled from his mouth and his head pounded along with the ringing in his ears.

He could have avoided the attacks, but the only way to make Nagisa admit defeat is to let him beat him but to still win in the end. To defeat him when he thinks he gained an upper hand.

Perfect victory

So he braved through the now stronger punches, blocking some and then it's time. He upper cut Nagisa and the blunet finally fell onto his knees.

That's the end! Karma raised his leg and used an axe kick, hitting the blunet straight in the head.

Nagisa was down on the ground, unmoving, face contorted with pain. Karma stood over him, waiting for a movement to hint of a pending attack. When none came, he wiped his sweaty and bloody face and calmly walked over to his fallen knife and picked it up, turning back to his former closest friend, now farthest enemy.

I don't think a place where I can lay my thoughts on the open like this will ever come again, he thought back to all those moments with Nagisa and the class. The fun and the embarrassing. The angry and the calm. The happy and the worry. He looked over to the humanoid octopus who stared at them in silence and smiled.

But I will kill you Koro-sensei. I believe that to be correct.

Then he snapped around and raised his knife for a final stab.

Any moment now...

CLAP!

He knew it!

Karma bit his tongue, feeling how the paralyzing effect of the Nekodamashi take effect on his body, making it feel numb yet buzz with adrenaline.

It's about time! The last of your strength!

He looked up to see Nagisa picking himself up, hand already taking out the knife and pupils narrowing to slits. He could even see the illusion of blue-green scales cover around the lit blue eyes.

Excitement surged in him at the sight of the bloodlust, further motivating his stunned body, more electrifying prickles prickling his skin.

Just try to kill me, Nagisa. Use that talent of yours that I lack— a snake slithered around Nagisa's arm and knife that approached him in a high speed — I'll smash it to pieces and win!

Nagisa yelled in frustration as the snake and bloodlust fused with the knife and Karma, despite the fear now clutching his heart, knew that if he will flick the knife away from the blunet's hand, it will be his win. His complete and utter victory.

I win—

His arm was already moving when he saw it. The hand holding the knife releasing it and the deadly blade flying toward him.

He discarded it?! Then it clicked as he saw the bloodlust-less blue eyes look at him in determination, arms spreading as if to hug him. He was unable to avoid it, but then the unexpected happened.

His heel dug into a soft spot and his knee bent, getting him out of Nagisa's arms. Blue eyes widened in shock and Karma rolled away, letting Nagisa fall onto his face.

The blunet sluggishly rose to his feet, face a mess of leaves and mud and streaked with red, defenseless now that both his knives were gone. Karma struggled as well to rise to his feet, face throbbing and lined with cuts and mud as well, hair sticking to his forehead and cheeks from the sweat. He was exhausted, body straining to keep moving, but when he straightened himself, he poured all of his remaining strength, he swirled around and kneed the blunet in the chest, sending the other crashing for the third time to the ground.

A sickening crack resounded in the clearing.

Blue eyes widened as the blunet coughed out a yell of pain from the impact, blood spraying all over the earth and curled into a ball, holding his probably broken left arm protectively.

Karma took a deep breath and approached the blunet, body on edge even when giddiness took hold on his thoughts. This is truly the end, Nagisa. You have nothing to use now.

He felt his body momentarily go numb and stumble again over another soft spot and cursed. If he hadn't bit on his tongue that time then he would have certainly lost and even then his body was greatly affected. Only his momentarily clumsiness saved him. How cliche. Pathetic.

Subconsciously an inhumanly wide smirk stretched his lips. Nagisa is truly scarily strong and he felt rare exhilaration from fighting him. But he must win this fight. He must get his point across even if it would cost him the blunet's trust. He is going to kill Koro-sensei and he won't let Nagisa take it away from him.

"Nngh…" Nagisa grunted as he pushed himself to his knee, scale-framed eyes looked up once again with snake-like pupils, staring at him intensely. An unbidden shiver went up Karma's spine.

Nagisa managed to rekindle his bloodlust in an effort of keeping his adrenaline and body going.

Truly remarkable, but surely you ca—

The blunet froze and turned his head to look at something behind him.

Karma stopped on his tracks, wondering if something is the matter. He couldn't feel anyone other than their classmates and teachers so he chalked it up to a last ditch plan.

But when Nagisa simply turned his back to Karma, anger pushed aside the excitement.

How dare that pipsqueak turn his back to him!? Is he giving up or underestimating him? Well, no matter, this is his chance. He'll just have to be prepared for anything.

He noticed his knife by his feet and picked it up again, lunging on the shorter boy.

He saw the blunet tense and felt a dark sensation of disappointment; he knew the other had something up his sleeve. But he gave it away too easily... unless—

"Karma-kun, watch out!" Nagisa stood, successfully stunning again said redhead, and unclasped a hidden holster under his vest just as a loud shot rang throughout the clearing.

BOOM!
