Chapter 2

Nagisa's pov:

Finally, it was Wednesday.

At the night, I had hardly slept at all, I was just too excited for that. And in the morning, I wasn't feeling tired at all, which was strange but great. I just hoped that the energy would last until the final lesson in school, when we would actually summon our first demons. Most of the day we'd prepare for it and rehearse everything just so Koro-sensei could feel little more safer. The yellow octopus had stressed about the summoning-night for the whole yesterday - and it had been a hell to us students, because Koro-sensei had been whining very, very loudly. And that also made us all nervous. Karasuma-sensei said that he believed into us, since summoning a weak demon wasn't hard, and neither was making contract with it.

The only problem was with the taming. None of us had never done it, and even if Koro-sensei would help us in school, the demon would be us at home - and if the master's mind would waver, the demon could go against him. Sure, we knew how to kill demons, and we had done it before. But never alone, there had always been at least one teacher with us. I didn't know could I defeat a demon without supervision, especially if it would threaten my family.

I sighed loudly as I continued walking towards the E-class building. The first class was starting within ten minutes, and we'd stay at school almost the whole night, since the night was the best time to summon demons. Sure, at night demons were at their strongest, but at night most of them were also in the move. It was easiest to summon a demon at night - we just had to hope that no one would accidentally summon a strong demon.

It wasn't forbidden or anything to summon a strong one, but everyone knew it would be stupid. The strongest demons were the most vicious, always finding a way to make their masters hesitate and then, it would be an easy kill for them. Like I told before, only the strongest Hunters could tame a strong demon. And even from them, it would take years.

But I would definitely become so strong, that I could tame any demon. I would find the demon-boy with golden eyes, and tame him. And possibly make friends with him. I just hoped that he hadn't already forgotten me -which was had probably already happened. Human live was like a blink of an eye to a demon, so weak, so fast.

"Nagisa!" I heard a familiar yell and turned around. Kayano, a green haired girl with golden eyes (had to admit, that the demons eyes had been prettier) and a very sweet nice, one of my closest friends was running after me. I stopped to wait for her and once she caught up, we continued our way together.

"Are you excited for tonight?" I asked.

"Yeah! I can't wait to see what kind of demon I'll be able to summon", Kayano answered cheerfully. Then she turned to look at me. "What about you? Ready to go?"

I sweat dropped and laughed nervously. "Well… I'm really excited, that's for sure. But I'm also nervous. What if I fail?"

"C'mon", Kayano chuckled. "We've been through this a hundred times already, Nagisa! You know what to do, and the teachers are there with us. It's simple - in class you've always nailed the summoning training. I think you're best at it, in our class. In the whole school, the best is of course Asano-kun…" Kayano stopped talking when her thoughts ran back to A-class and to the principal's only son, Asano Gakushuu, also the student-council president. Asano was a genius and best at everything he did. Of course, he was also very successful when it came to demon-summoning.

"True", I sighed. "I bet he'll summon a strong demon too. A demon who can actually take a human's form and possibly posses him. But I don't believe possessing Asano-kun is even possible. His mind is only set on studying and becoming better than the principal. No one, or rather, nothing can waver his mind." That was true as well, I had never seen the strawberry-blonde lose control of anything. He always had the strings in his hands - just like his monster of a father did.

Asano Gakuhou was a legendary Demon Hunter and a descendant of the first Hunter, which made him a big-shot. He had created the Kunugigaoka junior-high and high-school within ten years and made it the best in Japan. The principal was wise, well-organized, strong and determined to keep his school on the top. He had tamed many demons and earned the respect of the top Hunters in the world - of course, the principal was the fifth best Hunter in Japan. I of course looked up to him because of his great strenght, but I also disliked him. I had seen the way he tamed his demons, and it wasn't nice to watch. The principal was too cruel, even to demons. But of course, he didn't know that they had feelings too.

Every human or Hunter in this world was pretty fixated on the fact that demons were always bad. I believed other, because of the demon-boy who had saved me. I had yet to find out why. But if there was a one demon who cared, why not more?

"He's good, alright", Kayano nodded. "But we aren't that bad either. Believe in yourself, Nagisa! We can do it!"

"Yeah, you're right", I said, smiling kindly to her. We had already reached the classroom and we were now preparing for the first lesson. The class was slowly getting filled with our other classmates, who all seemed pretty excited. "So, what kind of demon would you like to tame?"

"An Earth Demon would be nice", Kayano answered. I knew very well that using magic was Kayano's biggest ace, since she was pretty good at concentrating. I was good at summoning and I had always succeeded on demon taming - but we had only trained it with demons who were somehow locked or chained up. I was pretty average when it came to fighting and magic. "You know that out of all demons, they are the weakest and probably "nicest". I'm not all that strong and we all know it."

I nodded to that, but at the same time I was smiling, so Kayano wouldn't feel so bad. There were many good fighters in our class - as well as magicians. But we weren't all that strong or that good, I believed that anyone from the main building could easily defeat me. But as a class, we were probably the only ones who knew what cooperation and teamwork meant.

"Good morning class!" Koro-sensei said happily as he arrived with Karasuma-sensei and Bitch-sensei. "Are you all excited for this night?"

"Yeah!" half of the class answered happily, while the other half didn't seem to know what to think of it.

"Nurufufufu", Koro-sensei chuckled. "I'm sure everyone of you will succeed. Don't worry, we teachers will be there with you and we'll guide you through it all. If you really don't feel like summoning a demon tonight, you can always say it to us. We all understand that this is exciting, but very scary for you as well. But let me tell you - succeeding in summoning your first demon does not only bring satisfaction, it brings joy and it helps you to understand the world of Hunters little more."

"But let us remind you", Karasuma-sensei said, his voice serious as ever. "A demon will also bring responsibility, you are the ones accountable of the demon. Do not let it break the contract - and just for your own safety, do not summon a demon too strong for you. I don't want to see any possessed students tonight, okay? You all know it takes time to get the demon out, if it goes inside your body and posses you. Don't make me go through anything like that."

That made me wonder - had Karasuma-sensei been through something like that? Did he know someone who had been possessed? Bitch-sensei had a concerned look in her sky-blue eyes, as she glance at her co-worker, but it was gone as fast as it had come, when she turned back to us. Unlike usually, I could know tell that her kind smile was a real one, and so was the confidence in her eyes.

"You kids are strong", she said. "You can do it. And like this damn octopus said, we'll help you all."

"Damn octopus…?" Koro-sensei asked, sounding hurt, but Bitch-sensei just ignored him. But it did make the atmosphere little more relaxed.

**Ansatsu Kyoushitsu**The arc of Demons**

The clock was ten in the evening, when we started. The whole day, we had been rehearsing everything once again, but this time, everyone had done it more seriously than ever before, memorizing everything. And now, we were standing outside the E-class building, each of us drawing our own magic circles. Everyone in the school was doing this today - or those, who were in the third grade. Even from the E-class building, you could see the glow made by the magic-circles from the main building. They had already started. Koro-sensei also told us, that there were now many Hunters all around the school-area, making sure that no demon would do harm to anyone.

I had just drawn my own magic circle, and I was quite happy with it. And it seemed that everyone else was done too.

"Okay, students!" Koro-sensei said, a big smile on his face. "Now, I'll ask you few essential questions. Why do we need to summon demons, if we hunt them?"

Isogai-kun, a dark brown haired boy, who was also the males class representative, gave the answer. "Hunters use magic and magical weapons against demons, but usually, against stronger ones - who go by the name demon-kings - these objects alone are useless. That's why, we Hunters summon other demons and use them to kill each other (which is quite cruel, if you ask from me). But first, the Hunter has to tame the demon."

"Correct, Isogai-kun! Splendid as usual", Koro-sensei nodded happily. "We do need demons to kill other demons. But it's risky as well - taming a demon-king level demon is not easy. It takes time and a strong will. But I believe, that all of you will someday be strong enough to do that."

"I want to kick Satan's ass", Terasaka-kun said bluntly.

"Nurufufufu, interesting life-goal you have there, Terasaka-kun", Koro-sensei chuckled. "I expect you to do that."

"Hah, that's impossible", Maehara-kun said, as he shook his head. "Satan is the strongest demon there is - a Fire Demon too. There's no way you could possibly defeat him. He doesn't even come out of Hell!"

"So what?" Terasaka growled angrily. "I'll go to Hell - but first I'll tame all of his children. Even he can't defeat all of them."

"I don't think this is the time for this talk", Bitch-sensei suddenly pointed out. "Just summon the demons already."

Well, someone is back to her usual self, I thought. Bitch-sensei had been nice all day, supporting everyone with kind words and smiles, and teaching us some new techniques that would help us to seduce a demon. But I didn't really think that those techniques would help us, but it was nice of her to even try to help us.

"Irina-sensei is right", Koro-sensei said. "We should now start the summoning. Only three at a time, okay class? Not that I'd suspect that any of you would fail… let's just follow the school rules."

"Yeah, right", Nakamura sweat dropped. We all doubted that Koro-sensei followed the school rules - he was a very free-minded teacher, who did what he wanted. I just guessed that he had been a lonely Hunter, who always did things he himself wanted and not what others did. Not that he really showed that side of him to us.

"Isogai-kun, Hayami-san and Kanzaki-san, we'll start with you three", Karasuma-sensei said. "You and Irina, take your places." Our most serious teacher always refused to call Koro-sensei by the name our class had given him. For some reason, our homeroom-teacher refused to tell us his real name - so because we couldn't keep calling him just teacher, Kayano came up with a great name. Since Koro-sensei was a strong Hunter and in his new form, he was almost invincible. I really wondered, did Fire Demons accidentally make humans stronger.

"Why can't you call me by my name?" Koro-sensei cried. But he moved behind Kanzaki, the prettiest girl in the class. The yellow octopus was making sure Kanzaki would succeed. Bitch-sensei went to Hayami and Karasuma-sensei stayed with Isogai.

"Now, we'll start. Take your time, hurrying is never good when it comes to summoning", Koro-sensei said. Then all of the three started mumbling spell - which was creepy, because it all looked like from a horror movie. Glowing magic circle, strange creepy spells… and especially Kanzaki seemed scary, because there was a madly grinning, shadows dancing on his face.

It really gave me the creeps. And made me also nervous.

The three were done within ten minutes and all of them had succeed. Isogai had been able to summon an Air Demon, that looked a lot like a pigeon, except it was three times bigger. Hayami summoned an Air Demon as well, but this one was a hawk, whit sharp green eyes - very much like Hayami's eyes. Kanzaki had summoned a Water Demon, that would be something called a mermaid, but very fishy-like-mermaid. But the main point was, that they all succeed on their first try. And I could see from their excited and relived faces that they were very happy and satisfied with themselves. Most of my classmates - including me - gave them little a applause, congratulating the three at the same time.

"Very good!" Koro-sensei said approvingly. "Now, make a contract with them." Making a contract was pretty simple. You needed to give the demon a taste of your blood and then simply, learn each others names. Easy. Except, demons didn't usually want to tell their real names. It could take few days to actually get the demon cooperate. But weaker demons were easier. Of course, we'd also make some rules to the relationship between the demon and ourselves. And the demon would have no other choice but to cooperate.

I kept watching the others, as the teachers moved on and the summoning continued. I was starting to feel little more relaxed when I saw that everyone was doing well. Those who had already summoned and made contracts with their demons, were now chatting with each other, their new demons right next to them. Finally it was my turn. Kayano and Terasaka were the last ones with me and Koro-sensei was standing right behind me, seeming now very relaxed. Guess he now trusted into our skills little more.

"Relax Nagisa-kun", he said to me. "No need to feel nervous. Just do as I have taught you."

"I know, sensei", I nodded, giving him a slightly irritated glance. "It'll be fine, I can do this."

Koro-sensei's grin changed into a warm smile. He let out a small chuckle and patted me on the head with one of his tentacles. "I'm happy to hear that. Now, let's start."

I nodded and then I started to mumbling the spell.

"The God will forgive… The light shall be cast over Hell…"

"To give me power…"

The rant went on for five minutes like that, and I was really lucky that I remembered every word. But when I was half-way through, I felt a strange pull in my stomach and I could see how a dark circle opened in the middle of the magic circle, and something started to slowly come out of it. I could feel somehow familiar warmness around me and power flowed through my veins. It was very strange, I had never thought that summoning a demon would make me feel so… powerful.

"…And here by, I will take command over you, demon. Heaven give me more strenght, I will resist the call of darkness. Demon - obey my command!"

And then it was over.

The glow disappeared and I finally saw the demon in the magic circle fully. And it was… a cat?!

"I summoned a cat?" I said aloud.

Koro-sensei let out a amused snort and he patted me on the head again. "A cat-demon is one of the oldest demons there are. It might not look much, but you did well Nagisa-kun", he said. But then his voice turned more serious. "This cat though… I can't tell what kind of a demon it is. Maybe an Earth Demon? It can't be a Water or Air… and definitely not a Fire Demon."

I didn't really listen to Koro-sensei, I was too captivated by the cat-demon who sat on the middle of the magic circle, its eyes looking directly at me. The cat had a fiery red fur and it looked so soft that I wanted to touch it, but I resisted. Touching could make the demon angry. It had cute pointy ears and a slight pink nose. The cat-demon had it's tale around its cute little pawns. But I definitely loved its eyes the most. They were golden and sharp - just like the demon-boy's eyes had been. And so deep as well!

"Nagisa-kun, you can admire its beauty once you've signed the contract. Remember to be strict with it. A demon does not follow -"

" - a weak master, I know, sensei", I sighed. Then I turned my attention back to the cat-demon. It was still sitting there waiting for me to do something. I swallowed nervously, but as I started to talk, the fear left me. I still had the warm feeling inside of me and so, I didn't fear. I took out a little knife and made a cut to my thumb, and then I offered it to the demon. It took a good moment until it started to lick the dripping blood from my thumb. It tickled a little and I couldn't help but smile. The cat-demon tasted only few drops, but it was enough.

I retreated my hand. "My name is Shiota Nagisa", I said. "And I want to make a contract with you. Will you tell me your name?" The whole time, my voice sounded lot more confident than I felt.

"My name…?" The demon's voice asked inside my head and it startled me a little. It had a honey-sweet voice, but that was common with demons. But there was also something familiar in it… I just couldn't tell what. "You don't seem to be strong." The cat let out a angry hiss and Koro-sensei moved slightly towards me. But I was able to stop my teacher.

"I wont follow you. You're weak", the demon continued.

"No."

It was a straightforward answer. And the whole time, I looked straight into the demon's eyes, like I would've been challenging it (which in reality wasn't really wise). "Tell me your name, demon. We'll make a contract and I will tame you", I said, using more force in my voice than usually. I wasn't used to it either, but it really seemed to surprise the demon, because all the anger disappeared from it.

"Tell me your name", I said again, calmly and a small smile on my lips.

And that made the demon let out a laugh. The cat started to purr slightly, its tail moving smoothly around it. "You sure change quickly, Shiota."

"Call me Nagisa."

The cat-demon closed its eyes for a moment. When it opened them, I could swear that I saw fire in them. "My name is Karma."

The change of mind surprised me. "So easily…? But seriously, your name is Karma? Who gives their child a name like that?" I couldn't help but ask. And right away I regretted it, but apparently the demon only found it amusing. It started to purr even louder, and I could hear the chuckles in my mind.

"Obviously the ones who created me", Karma answered. "Now, will you let me free? This circle is annoying me."

Now it was my turn to chuckle. "Don't even think that I'll fall for something like that. We have to set some rules first. So let's start." It didn't take long - I made Karma promise few things like: "Don't kill anyone from my family" and "Devouring souls while I'm taming you is not allowed". There wasn't really much more I could make him promise. I would need to tame him to make him submit to me. With training, we could possibly learn to fight together - and that was my goal at the moment.

"Koro-sensei, I'm done", I said to the yellow octopus who was still right behind me. "Can I wipe the circle off now?"

Koro-sensei nodded slowly, suspicious look on his face. "I still wonder what kind of demon he is… Did you ask him?"

"He can hear you", I pointed out. "And no, I didn't. Don't worry, I'll ask him later."

"His name?"

"Karma."

"Karma huh…", Koro-sensei mumbled, eyeing the still sitting cat-demon. "Be careful with that demon, Nagisa-kun. There's something wrong with it."

I gave the teacher a questioning look, but Koro-sensei dodged it, and went on to check on Kayano and Terasaka, while I wiped the magic circle away and Karma started to move around. I noticed how he refused to go any closer to the other demons summoned - he actually stayed very close to me. Karma didn't come closer than half a meter, but neither did he go any futher than two meters. I kinda liked it.

"Hey, Nagisa!" Kayano came to me, a squirrel-like demon following her. "I got an Earth Demon! Just like I wished, its name is Rei." She stopped three meters away from me, eyeing the cat-demon worriedly. Rei was right on her shoulder, but now it seemed to want to run away. "You got a cat - and wow, it's cute! And look at the golden eyes! What's its name?"

"Don't", Karma said to me in my mind again, giving a warning glare. "Don't tell her my name. I don't like that demon knowing it."

I sweat dropped, but I still decided to listen to Karma. "I'm sorry, Kayano. I'll tell his name to you when there's no other demons around. He doesn't trust anyone."

"Ah, I see", Kayano chuckled. "I can feel that Rei is very uneasy around your demon. Maybe it's a superior one?"

"Yeah, maybe", I nodded. "I don't know what kind of demon it is, but Koro-sensei guessed that he is an Earth Demon too."

"You don't know?" Kayano asked, surprised look in her eyes. "Then, why don't you ask?"

I turned to look at the cat-demon, who was sitting again, his golden eyes wandering around the yard and the other demons. "Yeah… I should."

"Well then", Kayano said, smiling kindly. "We are all going home now. Koro-sensei will keep a little prep-talk, and after that, you have all the time you need."

I nodded once again. But just by looking at the golden-eyed cat-demon, I could tell that this wasn't going to be easy.

**Ansatsu Kyoushitsu**The arc of Demons**

Karma's pov:

I found humans really interesting. Seriously, they summon demons and make us kill each other - quiet amusing really. I didn't really care that I would need to kill someone who was the same with me, it was nothing new to me. But more amusing was how stupid they really were.

Prep-talks about how to tame a demon? Bullshit, if you asked from me. But it was interesting to listen to, at least - the whole time I just really wanted to burst out laughing and take my real form.

It had been surprising that a weakling like "my master", had been able to call someone like me. And without realizing it too! But it was partly my fault as well - leaving Hell made me little weaker and so summoning me possible. If my father would find out… he would get really pissed, let's just say that. But luckily he didn't know yet.

"What kind of demon are you, Karma?" Nagisa, my new master asked me when we were walking towards his place. I was still in my cat-form, as I liked to put it, and I walked right next to the blue haired boy.

"Do you really want to know?" I asked from him. Since I was in my cat-form, I couldn't talk like normal people. But hey - at least I could say more than my name and yes and no, unlike many other demons.

"I need to know", Nagisa said. "I'm going to tame you, like I said. It's easier for me to do that if you tell me what your element is."

"You know that there are demons without any particular elements", I said. It was better for me to dodge the questions for now. It was still quite surprising that he hadn't realized already - I gave a good hint when he summoned me. I thought that it would be enough for him to stop, but guess I was wrong. He did show some amazing determination when ordered me to tell my name.

I liked that, it gave me a strange feeling, that I couldn't explain. "Don't worry, Nagisa. You'll find out soon enough", I said to him before he managed to say anything. Nagisa gave me an annoyed glance, but it disappeared soon when suddenly there we were attacked by a big monster. It came out of nowhere, and it looked like a huge bear mixed with a lion. So, basically, it was just very weird. I could tell that it wasn't strong enough to be considered a demon, but its element had to be earth. Both me and my new master jumped back, the bluenette having a surprised and little nervous look in his eyes.

The monster let out an angry growl, its bizarre red eyes looking straight at me for some reason.

I don't think that I've angered any monsters lately, I thought. But of course, soon I found out why exactly was the monster looking at me with so angry eyes. When it charged towards me, I could hear its voice ringing in my head.

"Young master… your father has ordered me to get you back…"

Yeah right, like I had any intension of going back. And now I was chained to Middle World, since I had a master. Of course, I had more reasons behind my decision to leave Hell and yep, one of the biggest reasons was my asshole-of-a-father.

"Karma! You can stay back", my master said to me suddenly. I had dodged the monsters attack easily and I was now sitting on a tree that grew by the road. Nagisa was right under the tree, his eyes wandering from me to the monster. "I can take care of it myself - monsters aren't nothing unusual around here."

"Are you sure?" I asked, my tail flicking around my body. (I really liked my cat-form, it was cute.) My new master gave me a confident smile and nodded. I felt that strange feeling pulse through me again and for a moment, it also felt like my power would've drained a little. I had never been summoned before and neither had I made any contracts with humans - my father strictly forbid it from me. Maybe this was part of the contract, me giving part of my powers to my master. It sure felt little annoying, and I had no intension of staying under Nagisa's control for too long. I despised humans… or that's what I wanted to do, but for some reason, for my whole life, I had never been able to feel complete hate towards human.

More than anything, I despised myself.

My father always said to me, that I had no reason to care about humans - they were weak creatures, who used us to kill our owns. Like I told before, I was fine with it - but I still didn't enjoy it too much. He also said that I had no reason to hate myself so much, but I really couldn't help it. Of course, it hadn't always been like this but…

"I'm done here", Nagisa's voice rang through my head and I looked at him in surprise. While I had been in deep thought, he had defeated the monster and he was now watching me worriedly. "Is there something wrong, Karma?"

That made me let out a bitter chuckle. No one ever asked if I was okay - or not anymore. "Nothing is wrong. Except that I have to follow a human now."

My master frowned at me. "That was mean to say, Karma. Humans aren't so bad and I know that neither are demons. We of course have our flaws but so do you." He was quiet for a moment, blue eyes looking sad. "I know for sure that demons too have feelings. And my life goal is to prove that to everyone. So, maybe we could learn to cooperate." Nagisa turned his eyes back to me, a hopeful look in them And that made me snort.

"You think that I'll just agree on that? Don't be ridiculous, human. I wont submit to someone like you - and I don't believe a word you say", I growled and jumped away from the tree, right next to my master. "Lower you guard and I'll take my leave, got it? I wont follow a weak master."

Nagisa sighed tiredly and nodded. "I know. But things will change someday, believe me", he said, a grin flashing over his face. "Let's go now, I'm tired. You are probably feeling tired too."

"It's night, you dimwit. Demons are out at night", I purred, as we started to walk again. The streets were pretty empty, only few people walked around and all of them kept eyeing Nagisa and me weirdly. But I decided to ignore it, I was actually pretty used to being stared at. "But I guess I need to get some rest if you're going to make me your slave and work me over days."

Nagisa chuckled. "I'm not going to make you my slave, Karma. You'll be my demon, and you'll stand by my side. Once we know each other little better, you'll (hopefully) change your mind about me. I'm not that bad."

It was my turn to chuckle. Humans really are weird, I thought. But this might not be so bad. At least father doesn't know where to look for me - especially when I'm in my weak form. No one from Hell would guess that I'm being tamed now. It still sounded weird to me - a human boy was going to try his luck with me. Even if I didn't hate humans as much as I should, I really had no intensions of being tamed.

I wanted to be free of humans and other demons. Call me a lonely wolf, but I really hated people. Around other demons, I was always picking a fight, teasing or doing other sadistic things, and no one really liked me all that much. I didn't care. I didn't want to care. I pushed everyone away, but that was something expected from a demon. I didn't need anyone and I didn't ever want to have any weaknesses. I needed to be strong like my father. But at the same time, I wanted to be more like someone else… There was a person I truly admired - or rather, there had been a person I admired.

"We're here", Nagisa suddenly said. We had arrived to a boring looking row-house, and Nagisa's home was the number three. The door was boring was boring too, nothing special or big, unlike my house. "I know it isn't much", Nagisa said nervously. "Since I don't really know how you've lived until this day… But I hope that you'll still feel comfortable here!"

"I don't care", I mumbled. "Your home doesn't matter to me - this wont be permanent."

Nagisa chuckled sweetly, his sky-blue eyes glimmering in the dim light. It was already midnight and I was surprised that there even was light. "I can still hope, can't I? But don't start complaining now." I snorted loudly, my tail whipping the air around us - had to say that my master really was annoying. But there was still something about him that interested me. And the whole time I had had a strange feeling that I knew him somehow… Well, I'll find out what it is later.

"Now then", Nagisa said as he put the keys in the keyhole and twisted them to the right. "I welcome you to my humble home."

And then he opened the door.

Later on, I would blame myself for not noticing the dark figure watching us.
