**Ansatsu Kyoushitsu**The arc of Hunters**

Chapter 4

Nagisa's pov:

How did such a bright day change to a dark one so quickly? All it needed was six demons, and my day was ruined. For good.

"All students, I want you to stay out of this", Koro-sensei said, sounding and looking serious. He had no smile on his face, and I could hear the disapproval in his voice. "Irina-sensei shall protect you while I and Karasuma-sensei take care of this, alright? Don't do anything reckless - I don't want anyone to get hurt today."

"Sensei…", Okuda-san muttered quietly, her voice shaking just like her frail body. "Will you be okay?"

The yellow octopus who stood in front of us as our shield, turned to look at Okuda-san, his smile back on his face. This time it wasn't a teasing smirk - it was a warm and reassuring smile. One of his tentacles patted Okuda on the head lightly. "Of course I'll be fine. I'm your teacher, and it's just part of my duty to take care of you. And don't forget that your teacher is a Hunter too", he said. "This isn't a first time I've fought with demons."

He couldn't say anything more, when suddenly the ground under us shook and we were split in two, a huge crack between us. The crack was at least four meters wide and Koro-sensei was only on the other side - while there was no one on the other. It was pretty close that few of us students didn't fall in and to the darkness. I looked over the edge to see broken water-tubes and I couldn't even tell how deep the crack was.

"Are you done talking, humans?" Leone growled to us and without even looking, I knew she was the one to split us apart. She knew what she was doing - splitting us apart so we would be easier to defeat. Leone was right, we were inexperienced. We still had no idea how to use our demons in fights. "Kill them!"

The six demons split in three, three of them attacking the ones who were on the other side, while three attacked my side. I heard Kayano scream in horror when one of the demons almost hit her - but luckily Koro-sensei was fast enough to go between and push the demon away. His hit still didn't have any effect on the demon - that looked like a leopard and man mixed together. The Earth Demon just lunged at Koro-sensei again, this time looking even more furious than before.

"Watch out!" Karma's voice yelled in my head and I looked away from Koro-sensei, just in time to see Leone's fist aimed at my face. Something red jumped on the way before I had the chance to move and took the hit for me. I watched in horror as Karma was send flying back, his small body hitting the ground with force.

Leone stood now right in front of me, seeming little disappointed. "Tch! Damn cat-demon", she mumbled. I luckily found my power to move again, and so, I turned around and ran to my demon, who was lying on the ground. I was lucky that Leone seemed to find Karasuma-sensei more interesting after that, since she lunged at him instead of running after me.

"Karma!" I yelled once I reached him, my hand touching his soft fur. "Please be okay."

"You dimwit", my demon hissed, raising his head from the ground. His golden eyes were burning with anger. "Don't let your guard down. I'm not going to jump and protect you anymore. That fucking hurt."

"Thank god", I sighed. "You're okay."

"Screw you and her. I'm going to kill it."

Yep. He was okay.

I could hear more of my fellow classmates screaming in panic and running around the backyard - if it wouldn't have been such a serious situation, I would've thought that it looked kinda hilarious. But now everyone was running because no one wanted to be killed by a demon. I could relate to that.

"C'mon now", Karma said as he got up, shaking the dust off of his red fur. "We can't just sit and watch. Let me kill them."

"As if you could", I said to that. "They're stronger than you are - and there are six of them. You can't possibly defeat all of them."

Karma was quiet for a moment, his eyes traveling around the yard, pausing to look at every demon for a moment. I had no idea what he had in his mind, but I swore I saw a smirk on the cat-demon's face when he turned to look at me.

"I'm stronger than I look", he said, eyes full of mischief. "And I know how to draw their attention to us."

"What?! We're not supposed to draw their attention!" I yelled. You're insane, was I wanted to say. "Didn't you hear me? They're stronger! Demon-king level!"

"I heard you, dimwit. But I have a plan, so don't worry", Karma meowed. "Get that asshole-friend of yours here. I'm giving him some use."

Asshole-friend? "Who's that?"

"The one who wants to kick Satan's ass."

Oh. Oh.

"You're talking about Terasaka-kun?" I mumbled, my eyes scanning my surroundings. I soon found Terasaka hiding behind a big rock, far away from the fight. He looked really scared, but I could also see a guilty-look in his wide eyes. "What do you want to do with him?"

Karma let out a sinister chuckle. "He obviously wants to do something, but doesn't find the courage to even stand up. The guilt is going to destroy him, and he's going to end up doing something reckless and stupid. I'm giving you a chance to stop him before it's too late."

"I don't get it", I bluntly said, making my demon sigh loudly. I even heard him mutter idiot.

"Humans do stupid things, let's put it that way", Karma said. "Your asshole-friend is going to do something reckless that is going to cost him his life and probably more. Do you want to stop him or not?"

"Of course!" I nodded. "So, you have a plan? And you're not trying to trick me right now?"

I knew Karma smirked even though I saw nothing on his face. "You tell me."

My answer to that was to stare at his golden eyes for a moment - and again, I got lost into the deep eyes, admiring the endless and breathtaking beauty. I swore that the colors changed from lighter gold to darker, and I could see burning fire in them. Karma was like a flame, his fur fiery and eyes golden and warm, despite the lack of warmness in his actions. He was always radiating warm air like a hearth. Just then I started to realize that he really reminded me of fire, no matter what way I looked him…

"Karma, about your element…", I gulped, earning the attention of my demon. "You haven't told me what it is."

"Ahahaha~, is this the right time to be thinking something like that", Karma chuckled. "But I have feeling that you'll find out today. It was never even a secret to begin with."

"Ri- right", I nodded. "Let's go and talk with Terasaka-kun now…" I stood up and started to run towards the still hiding brown haired student. I didn't know what Karma was going to do with him, but I hadn't seen any doubt in his eyes. He knew what he was doing. And I had to find the courage to trust him. "Terasaka-kun! Are you okay?" I yelled once we reached the brown haired boy and his hideout.

"Hu- huh? Oh, it's just you Nagisa…", Terasaka muttered, his voice shaking a bit. "Yeah, I'm fine."

I sighed in relief. "That's good to hear. So, you're not up to something stupid, are you?"

"What?!" Terasaka asked, sounding annoyed. "You're the one who has been running around the yard, demons after you. I've been doing my best to hide…" He looked guilty again. "Even though, I should be helping others… Y'know, it wasn't my fault… I was tricked…" Now his eyes were full of despair and he sounded plain desperate.

I didn't get to answer, when Karma went and bit his hand hard enough to make it bleed.

"Karma!" I yelled at the same time Terasaka yelled 'Ouch!'

"Control your fucking demon!" the brown haired student continued.

"Give him a taste of his own medicine", Karma told me. "He needs to hear you out. Make him see that a Hunter can't be scared to face a demon."

I bit my lower lip and then I actually smacked Terasaka on the head, quite hard too. "Get up you asshole! This is not the time to whine and blame someone else! You are to blame about this as much as your demon! She tricked you - sure! But that's what demons do!" I yelled, as I grabbed him by his collar. "You have to take the responsibility! A Hunter can't be scared to face a demon, Terasaka! Look at our classmates - even Okuda-san has found some courage to help our teachers! Don't you see?!" I looked at my classmates, who had finally calmed down and were now helping our teacher as much as they could. Even small spells helped and we knew it. Karasuma-sensei was having trouble, since he had two demons against himself and Koro-sensei was currently fighting with three others, while Leone was going head to head with Bitch-sensei.

But none of them showed any signs of fear - all of them fought just like Hunters were supposed to fight.

"Even we can do something", I said, calming my anger down. "Terasaka-kun… We need you to help us. Don't be a puppet in the hands of your demon. You have a free will, you have the strenght to go against her. Remember that you have a goal - a dream. Satan is far stronger than any of these demons." Terasaka stared at me in surprise when I brought up his future goal. I smiled kindly.

"I believe that you'll be able to fulfill your dream, but first, you need to learn what it really means to fight with demons." I stood up from the ground, turning to look at my fighting friends. "No matter what, make a tomorrow for yourself. And that means you have to fight. Find the courage for that."

"We need to stop Leone", Karma said to me, when I was finished with my talk. "You know binding spells, don't you? Use as many as you can. If the leader is cut off, the followers will lose their will to fight. Basic knowledge."

"Got it", I nodded. Then I glanced at the still hiding Terasaka, who now seemed to think about my words. "Terasaka-kun, I know you're good at using binding spells. Well, now would be the time put them into use. We need to slow Leone down so Bitch-sensei will be able to finish her off. I'll need your help. In or not?"

The brown haired boy gritted his teeth together loudly, his hands clenched to fists. I could see how his body was shaking, but there was something new to his scared aura. And when he looked to me, I knew that he had made the right decision. The determined look in his eyes told me more than enough - I saw no doubt in him.

"Hell yes I'm in", Terasaka growled. "I'm going to make that bitch pay for tricking me!" He stood up from the ground, eyes now on Leone, who seemed to be winning Bitch-sensei. "Let's go."

A small chuckle escaped my lips. "Glad to see you changed your mind."

"This wont be easy", Karma warned me. "You still can't be reckless. Don't let your guard down."

"Thanks for the advices, Karma. It really helps me to stay clam", I said. The cat-demon just shook his head, almost non-existing purring ringing in my ears. "I mean it."

"Sure you do. But remember, I've meant every word I've said too. I'll try to get free, just give me the chance. Despite the fact that I saved your ass, this contract wont hold me down for too long." His golden eyes were narrowed at me, which made me little nervous. It was obvious that he wasn't joking, it had always been.

"I get it. Now, let's go."

**Ansatsu Kyoushitsu**The arc of Hunters**

Karma's pov:

I get it?

The human-boy was joking. He obviously didn't get it at all. I was sure he didn't get it, no one ever did until it was too late. Wasn't that asshole-friend a good example? He was completely fooled by that Earth Demon. It was quite funny to me, but not to the humans. Usually, I would've laughed it off and killed them already. But because of the contract I made with Nagisa, I couldn't even take my human-form anymore, unless I got him to say certain words.

I couldn't kill any of the demons, unless Nagisa ordered me to.

Which I doubted he would do, since he was way too nice. I did admire his will to become a Hunter - and the fact that he wanted to change the world? That just proved that humans weren't all the same. Just like demons, I guessed. I was pretty sure that no other demon thought ill of themselves, but I wasn't just any other demon.

I was supposed to follow my father's footsteps, to become something far greater than any other demon. To become the next Satan - or that's what my father wanted me to become. But you know, screw him! I have older brothers too, so why couldn't one of them become the next Devil? My father knew very well that I didn't have the will to become like him.

No, not after what happened year ago…

"Only higher binging spells will work on her", my master's voice woke me up from my thoughts. We were now standing about ten meters away from the blonde teacher and Leone aka the-damn-annoying-bitch-demon. Nagisa had gathered up two other friends, the green haired girl, Kayano (or whatever her name was) and a dark brown haired boy - Isogai? "Each of us will pick a different spell, and I'll take the highest one, since this is my specialty."

"Got it", the asshole-friend nodded. "You start."

My master started to mumbled some stupid spell of his, and soon enough his friends joined him. They were all kneeling on the ground, eyes closed and wide open for any attacks. Stupid really, but I guessed that left me to take care of the protection. I didn't know had the blonde teacher or the-damn-annoying-bitch-demon noticed us, but I hoped not. Nagisa was partly right - I was too weak in this form. I could only be a punch-back for a moment.

Why the fuck didn't they get someone to protect them? I whined in my head, my tail flicking around. But I knew better than bother my master now, or the spell would be broken. It seemed to have effect on the-damn-annoying-bitch-demon, who started to slow down. But of course, fucking of course she just had to turn her eyes towards us. I heard myself hiss, when for a moment the animal's senses took over me. That was the side-effect of being too long in the form of a cat - I would slowly start to actually resemble it from inside too.

And at the moment, the cat inside of me wanted to make a run for it. The damn-annoying-bitch-demon was looking directly at us, her red eyes glowing dangerously. The blonde teacher tried to attack her, but obviously she was now outmatched. Funny how demons got stronger when they were angry - this bitch got ten times stronger, smacking the blonde teacher away with one punch.

"Nagisa, now would be the time to run away. She's angry, your spells are too weak!" I yelled to my master, smacking him lightly with my front pawns. His eyes opened, and without any hesitation, he told everyone of his friends to get up and run. Had to admit - for such a newbie to the cruel world, Nagisa was unusually calm and brave.

But should've guessed that we were too slow.

In a blink of an eye, I found myself in the hands of the damn-annoying-bitch-demon, her left hand pressing tightly my throat. Nagisa was lying on the ground close by, and his friends were scattered all around us, their bodies unmoving. I could still hear their heartbeats, so they were just fine. But fuck - if I wouldn't get the order to kill this bitch, I would be the one killed.

"Looks like the game of cat and mouse has ended", the damn-annoying-bitch-demon purred, a disgusting smile on her face. "Bluenette, watch closely as I'll kill your first demon on the second day. Can you believe it? It's been just one night and you'll already lose him." Cruel laughter left her mouth and the bloody-eyes turned to look at me.

"You have a familiar aura, little cat-demon. I realized it yesterday and I've wanted some answers ever since. Maybe eating you will give them to me, ne?"

"Stop!" my master yelled, his blue eyes suddenly full of pain. I could see that he was wounded, probably few ribs broken. Either way, he was hurting. It gave me a sickening feeling - and I blamed my master. "Don't kill him! I have still so many things I want him to learn! And I want to learn too!"

What the hell do you want to learn from a demon? Death? Pain? Loneliness? I thought, my breathing becoming harder when the damn-annoying-bitch-demon squeezed my throat even tighter.

"Please", Nagisa said, his right hand reaching out for us. "You don't understand… there are so many things I want to show him… don't kill him."

This seemed to shock both me and the damn-annoying-bitch-demon.

A human? Begging for a demon? To spare a life that has only brought sorrow? Was he joking?

"Order me…", I coughed, my eyes narrowed at the blue ones. "Give me the order… I'll end this."

"For what?" I heard him whisper.

"If you order me, I can defeat all of them", I explained. "…Just give me the order. It's your decision. It's not like I would fear death - I actually would deserve it -"

"Karma!" Nagisa suddenly yelled, cutting me off. "I hereby order you - kill her!"

It all happened so suddenly, but there was no hesitation or fear in his voice or eyes that were now full of rage. Had I said something that triggered him? But his rage gave me strength, and because he ordered me to kill the damn-annoying-bitch-demon - and he didn't tell me how - I could basically do anything.

"Now then", I said, my voice now heard by others as well. Steam started to leak out of my body, as I prepared to change my form. The damn-annoying-bitch-demon seemed to realize what was happening because she took a good jump back, dropping me down to the ground. "I think it's a checkmate."

**Ansatsu Kyoushitsu**The arc of Hunters**

Nagisa's pov:

Karma's whole body disappeared into the steam for a moment, but I already knew what was happening. All of this would explain the warmness he was always radiating… why he was so confident on his powers, why he was arrogant and why his were always burning with fire.

Leone seemed too shocked to move any further, her bloody-red eyes wide in surprise and horror. It seemed that the other fights had ended as well, since it was quite quiet now. But I was too fixated on Karma and the steam-cloud around him, waiting for his true form to be revealed.

I should've known… How didn't I realize sooner?

Finally the steam around Karma vanished, and instead of a cat, there was a young teenage-boy standing there, a katana in his right hand. He was wearing a long dark-grey coat with a hood on it, which shadowed his face, covering almost all of it. He had black jeans a blood-red shirt under the coat, which was open and flowing in the breeze. His katana was sheathed, and it seemed old and like the boy in front of Nagisa wouldn't use it much. He was also wearing black gloves - but despite his dark choice of clothing, he was radiating warm light and air like the cat-demon who he had been just seconds before.

"You are…", Leone gulped, her body finally starting to move. She took few hesitating steps back. "Satan's son… you're a Fi-"

She was cut off by a sea of flames that appeared out of nowhere, and devoured her. I could hear her screams, but it didn't take longer than thirty seconds for her to be completely gone - there wasn't even ash left. Seeing this, her companions decided to run for it, but unfortunately they faced the same fate as their leader.

And for the whole time, the teenage-boy didn't move an inch.

The backyard was quiet, as most of us were watching the teenage-boy, like waiting for him to attack.

"Ka- Karma…?" I asked since no one else seemed to want to speak.

The teenage-boy turned around, the hood falling off, revealing his face. He had pale, perfectly smooth looking skin and perfect light pink lips that were curved into a small smile. His hair was fiery red and silky, few strands falling on his face. And oh, even in this form, I still loved his eyes the most. So beautiful gold, still glimmering in the sunlight. It was like those eyes would've held the whole universe, colored every golden shade possible, in them. I could go on forever… *sigh*

God dammit - to put it shortly, Karma was the handsomest guy alive.

"At your service!" the red head answered cheerfully, but his smile suddenly turned sinister and he was standing right in front of me, leaning closer a little. "Or that's what you'd like me to say, ne?" He tilted his head a little, still smiling.

"You're really him, aren't you?" I still had some trouble trying to comprehend it. The cute little cat had transformed into a hot guy, in less than a minute. "The demon I summoned… Karma."

The red head facepalmed. "How stupid can a human be", I heard him mutter, and that made me blush. "Yes, I am the demon you summoned. My name is Karma. And do you still want me to tell you what my element is? Or did you finally figure it out by yourself?" He smirked coldly.

"You are a Fire Demon", I bluntly said. "One of Satan's sons."

"Correct~! Wonderful to see that my master isn't such an idiot after all!" Karma said, his smile turning strangely cheerful. He even clapped his hands together a little. "You humans surprise me time after time. It took you only a one day to realize who you summoned."

"Please stop that", I mumbled, my blush darkening. And he did, but there was a still a small smile on his lips. But all of a suddenly there was a gunshot and Karma took three steps back. The golden eyes found the shooter faster than I did - Bitch-sensei was pointing her gun at the red head.

"Stay back", the blonde teacher said, her voice threatening.

"Wa- wait", I said, sitting up from the ground. I had few broken ribs, but it wasn't really that bad. It did feel painful and uncomfortable, but I didn't want anyone to kill Karma. Though, now I was starting to doubt that was there someone capable of doing it. "Don't shoot him."

"Nagisa-kun", Koro-sensei said, and the yellow octopus was suddenly standing behind me. "You do know that Fire Demons are extremely dangerous. They should be eliminated on the second you see them. Usually they are just too strong for that - but this one is bound to you. You make it weaker. He couldn't even take his true form until you gave out orders. You can order him back to the cat-form he had before, and then, we'll easily kill him."

I didn't dare to look at Koro-sensei, instead, my eyes had wondered back to Karma, who was looking at me, his golden eyes waiting for my decision.

"You want to kill me?" he said and for a moment, there was no smile on his face. But it was back very quickly. "Go ahead. I do deserve it."

"Why?" I asked, my anger building up again. "Why do you say such things?"

Karma laughed like I would've said something funny. "Why I deserve to die? Nagisa-kun~, I am a demon no matter what way you look at it." His golden eyes started to glow and the air got hotter. I felt the now familiar bubbling inside of me - every time Karma used his powers, I would feel it. His power flowed through me as my blood through him. "How many humans do you think I've killed? How long do you think I've lived?" the red head asked. "Don't be stupid, Nagisa-kun. Isn't killing demons what Hunters do? Hesitating might cost you your life."

Koro-sensei was right. The two of us were bound together. And as long as the contract was there, I wasn't going to let him die.

"If you've lived so long, why are you so bitter? If you've killed so many, why do you continue?" It was my turn to ask the questions. "Those who have seen death… they don't want others to see it too, am I wrong?"

Karma raised his brow at me. "That may go for you humans, but not for demons. I'll kill as many as I want. No one says I can't. No one tells me to stop. And that's because I'm a demon. Because that's what demons do. Because that's what I'm supposed to do."

"So, you're saying that you're no different from the rest of the demons?" I asked, frowning at the red head, who smirked as an answer.

"Wishing that I'd be?" Karma chuckled. "Too bad, I'm really not any better."

"It seems Nagisa got tricked just like Terasaka-kun", Kayano said in between. "You didn't know, right?" She gave me a worried glance. I shook my head to that.

"I had no idea."

"Doesn't that just tell how good I'm at hiding?" Karma asked.

"Hiding? Why do you need to hide? Did you escape prison too?" Bitch-sensei asked. That made Karma chuckle again.

"And why the fuck would Satan put his own son in the prison? He has never done it, and no matter what kind of things I do, he'll never do it to me. But it's not like I would bad things."

Yeah right, as if someone would believe you when you have such a dark and smug smirk on your face, I thought.

"Ahahaha, I can see that you don't believe me", Karma said. "But oh - I'm the nicest out of all my siblings. Believe it or not."

"Have you always been the nicest one?" Kayano asked.

"No", was Karma's blunt answer. "But now that the one who used to be nicer than me is dead, does it matter?" Karma's gaze darkened for a moment. "You were the ones who killed her anyway." I couldn't really catch what he said, but for a second, I saw pain and sadness in the golden eyes - but the bright smile was back there faster than I thought possible.

"How many siblings do you have?" Karasuma-sensei asked, and Karma answered it with a cold smirk.

"You think I'll tell you? I'm not stupid, I know how you work", the red head said. "You wont get information out of me, I'm not a traitor. Kill or not, it doesn't matter."

"Nagisa-kun…", Koro-sensei muttered, still waiting for my answer, for me to take action. But seriously, I couldn't. I couldn't order Karma to take his cat-form and die.

Because I remembered and I knew. I remembered who he was and I knew he wasn't cruel like the other demons. I saw it in his golden eyes, even if it was there just for a second. I now, I had no longer the will to order him to die. Just by looking at the golden eyes, I could only feel guilt and need to keep him alive.

Why did things like this happen to such beautiful creatures? Karma was unique, I couldn't kill him. I couldn't destroy something as beautiful as he was. We were bound together, dammit! Even if it had only been a day, he had shown affection towards me, he had protected me. Even if it had only been a day… To me, it was a miracle that he was still there. And right now, he was waiting for me to decide. To kill him, or not. His golden eyes on me - his life in my hands. I knew he wouldn't stop me. I knew he wouldn't say no to me. But I also knew that he wanted to live.

"Koro-sensei… can I try?" I asked from the yellow octopus.

"Nurufufufu", my teacher chuckled, and without even seeing his face, I knew he had a warm smile there. "I get you. Nagisa-kun, you want to tame this demon, despite the fact that he is a Fire Demon and Satan's son?"

"Yes, I do", I nodded.

"You do know what you're doing, do you?" Karma's voice whispered in my head, and I turned my gaze back to him. "Despite how it seems to you know, simple orders don't do much. You have a long way to go. I wont let you tame me. I hate humans. I hate everyone and everything." Karma's voice was still sweet as honey, but this time the honey was poisoned. "I'm not going to be tamed by any human."

"I've said this last night, but Karma, I will tame you", I said, a smile forming on my lips. "I don't care what you are, you're already bound to me. Make it hard. Fight back. But no matter what I'll tame you in the end."

The red head snorted, his bangs covering his eyes for a moment. He had a cold smirk on his lips again, revealing the sharp white teeth. Karma shook his head lightly. "Ahahaha, I knew it~. You humans really are interesting, she was right after all", he muttered, as he removed the hair from his face. The golden eyes were looking at me, challenging as ever, an already familiar glint of mischief in them. "Just so you know, Nagisa-kun. I'll make this extra-hard for you - just because you've showed more will than any other human before. And in the end -" the red head was suddenly kneeling next to me, his face only few inches away from my own. "- I'll devour your soul."

His breath smelled like strawberries, just like he himself seemed to smell. The air was obviously warmer around him, and he seemed to glow red light. Resisting a demon was really hard, especially now that he was so close. But this was just the beginning.

"I have no intentions of letting you do that", I said as the red head stood up. "And I have feeling you wouldn't do it even if you'd have the chance."

Karma gave me a questioning glance. "Why's that?" he asked.

"Because you're the one who saved me five years ago."
