Summary: A paintball fight lead to Karma feeling very indifferent about Nagisa.
But since Karma is unable to express his emotions normally, Karma's feelings are able to come across in action. And Nagisa wants to find the source.

Author's note: Since watching the anime a week ago I found I love this ship and I would love to start writing fanfiction again.
I do not own the characters or anything. Only the plot and action.
Please bare me with how I see the characters as I'm only basing it off how I see them i.e their emotions and how they act.

If you would like for me to add certain things or you don't like a certain thing, I will happily take this advice on board. :) This is going to be a few chapters to show all the story.
Please enjoy reading, and if you do please review!

Rated M for smut for later, possibly violence and emotions.


After this battle ended, Karasuma knew Nagisa was the best assassin of the group. The snake image didn't shake during the battle and it wasn't his imagination that he once thought. In parts, he felt himself quiver in fear, though, during the fight the man disguised it with a furrow.

It was about time to exploit and explore the blondes brutally and if he could master it. Without the rest of the class around, of course. They could focus on searching for a cure whilst he took Nagisa for time out occasionally.


And in a few weeks time, Karasuma had made a routine like his own training to improve Nagisa's strengths. It wasn't a push in the park, though, Karasuma easily became the father Nagisa never knew and their bloodthirsty instincts made their bond closer.

"Alright, came at me again but this time aim in between my shin and knee to get me over. It's not about strength, it's about precision." Once again Nagisa replied with a "Yes sir". Before the bluenette took the stance, all his kind nature went to the back of his mind and he meditated on his killer instinct.

"Too slow" The taller bellowed as he came after Nagisa, his speed made them face to face a hand going for his gut. But the snake was going for his nape for a taste, Nagisa saw the man move in slow motion and he stopped the force by ducking and turning to be behind the taller man.

Suddenly his legs were kicked where sensei said but he was caught and flipped onto his back. "Tch-" Nagisa winched to himself, I mean he had felt worse than this before, but they had been continuously switching between this move and another to master. Karasuma realised months ago that Nagisa worked better with a few new moves before he found ones in-between he liked.

The elder was distracted though as he had noticed this presence every session. It couldn't have been Koro-sensei or someone unskilled. Without hesitation, he threw a Koro-sensei knife toward the other student and with a guess he named the other figure.
Nagisa glanced in the general direction the knife was thrown and noticed red hair in the wind.

"Karma, come down here if you would" 'Karma' … But why.. the brunette pondered.

Karma in one of the highest trees looked downwards at the figures, he didn't return the gesture yet or call back in response. The redhead was actually trying to calm his thoughts and reassure himself 'nothing had changed'. 'Everything will be the same' but flutters in the pool of his stomach decided to tell him otherwise. It was unknown feeling Karma had never felt toward anyone before. It was possibly the admiration, the desire, the passion, the calmness and jealousy that powered him when watching and being around Nagisa. If that battle never happened, he would have never noticed these emotions. He felt the fight off defeat was taken to heart in many ways.

But without a thought in his face, a replacement smug look was back for the other boy. He used his core muscles to hang and jump tree to tree until he reached the bottom. "Yo!" He said beaming landing a few steps away from the two. Karma wasn't going to tell why he was watching, instead, he came across like nothing was happening.
"So how can I assist the greatest warrior?" He sarcastically said, bowing his head in 'respect' and the smaller rolled his eyes in response.
'Oh Karma' Nagisa thought but had to have a laugh, forgetting what the fuss was actually about.

Karasuma ignored it and instead made a proposal to the red head, but gingerly didn't make it obvious he knew about what Karma was doing every lesson. "Take my place, and perhaps Nagisa could learn more. I saw how you two thought and Nagisa was able to pick up other ways to use his body in one-hit kills."

"Don't have to ask me so nicely, without a doubt I will~" The resting Karma look came back which those two knew so well of 'oh I know how this is going to go.' His feelings weren't sure about this, his heart didn't have a rush of adrenaline like it did when they fought weeks ago.

"And bring it all, Nagisa" he chirped. Karma took a grounding position so he was unable to be moved. His arms came up and in front of him though to catch the small boy.

"Do you have to be so unserious about it?" The smaller huffed in a joking way, but his own slowly drifted back to no emotion so he could concentrate. He was expecting Karma to come like Karasuma would, but instead, Karma took no step and breathed without making a sound.

And 'without a doubt this was probably the best to make this work' Karasuma thought to himself, Nagisa was already making adaptations to his foot pattern around the boy. The bluenette was almost becoming a snake that was protecting her eggs from protection, his attention to how Karma focuses were very obvious in how sporadic he became. And with a leap, Karma nearly felt he lost Nagisa but with his feet grounded further into the ground, his arms were about to take on any move.

The smaller came from above with his legs trying to grip around Karma's body and his fingers acting like a dagger for the jugular veins in Karma's neck. But the redneck was getting quicker as he was strong, he grabbed the hips of Nagisa and raised him above his neck so he couldn't touch where he wished to kill.

But the entire thing was.. not harsh. It wasn't strong, it was soft compared to the usual Karma…

'Soft…?' The bluenette had to not let that feeling rush throughout him, like Karma it was an unusual feeling. And before he knew it, he was softly back on the ground.
As they continued the rough and tumbles, Nagisa tried his hardest to get past those defences as if they were like a wall, but what was returned was a slight smile, a hand up from the ground or pat on the head.

'Interesting' Karasuma thought as he smiled and continued to watch in silence. He didn't want to interrupt their exchanges this lesson.

Whenever these smiles were exchanged or touches happened, Nagisa could sense Karmas heart beats. 'This never could happen… before.. Why can I sense him? Why are they so fast.. Why is he so emotional?' Each time he was dodged or maybe close, the bluenette wanted to mention something. His own heart was becoming in sync with how irrational Karma's felt.


He was so exhausted by the time they were done, the only last shot he had for the man before he collapsed unable to move was a "Karma, come here".
Karma didn't expect anything from it, the scuffs all over the boy told him that. He had sweat dripping, his ponytails were about to fall out, he was covered in dirt and he couldn't sense anything that could kill him. The red head walked closer and before he knew, the boy was already close to him. Close enough, he felt fingers go to his neck, and suddenly the rational thoughts/heart beats had come to an end. He felt relaxed?! What was this part of Nagisa?

"You're dead!" Nagisa stood back about to give a smile in a very happy way but his eyes slowly rolled back to his head, his legs were about to give way and Karma caught him acknowledging this all was probably too much. He picked the boy up to put on his shoulder.

"I knew you cared," Karasuma mentioned, giving a smile. He didn't bluff it too much as he knew the boy had emotional distort at home currently.
"Same time next week? You seem to be getting as much out of this, thank you for your help". Karma was the best for Nagisa to acknowledge what he had was special, even the part where Nagisa could stop to sense how the other was feeling.

Karma had already begun to walk away, he didn't really want anyone to notice his predicament. Or Karasuma to say anything more than he could say.
"Yes, sir".
