The Island Arc begins

Chapter 1

Nagisa's pov:

It was a quiet and a sunny afternoon, and Nagisa Shiota, a seventeen year-old boy, was just walking the familiar path leading to a familiar building. It was the summer vacation, and yet, he was making his way to the school. To be exact, he was going back to the 3E-class. He and the others from the class, including Koro-sensei, Bitch-sensei and Karasuma-sensei, had planed a meeting. They had actually planned to spent the whole summer together - after this, they wouldn't see each other in a long time. Nagisa knew that, and it made him little sad.

So, now, they were prepared to have great time and fun, probably trying to kill Koro-sensei for the sake of the old times as well. It wasn't like they could actually kill the yellow octopus, but they could always try. And Karma-kun would do it, just for fun.

Yeah, Karma. The red headed demon. He and his golden eyes, and his mischievous smile. Nagisa missed them, he missed his friend so much. Karma had died, two years ago, in the fight for the sake of the world. He had saved Koro-sensei's life - no, he had saved everyone's life - but it came with a cost. Nagisa still felt guilty about it, because it had been him who caused Karma's death.

For two years, Nagisa had wished for the red head to come back like 'It was only a joke, I never died' - but he didn't come. No one heard of him, since he disappeared in the day the world was supposed to explode. He was gone, nowhere to be seen. Nagisa still wished that he would come back.

And finally today, he had seen something in the port of the town next to the old school (that Asano-kun lead these days). He had seen a flash of red hair and golden eyes. He had been walking to the school, when he had suddenly bumped into an another man, a tall and a fit one. When he had looked up, the man had already passed him, without saying a word. They turned to look at each other, just before the man disappeared into the crowd. He had red hair like fire and eyes like gold. So familiar.

Nagisa had frozen. But the man was gone as fast as he had come, leaving Nagisa all alone. Then Nagisa had realized, that it was possible for Karma to still be alive - in the same town, close by. He needed to tell the others about it. He needed to find Karma.

**Ansatsu Kyoushitsu**The Red Demon**

"Oi, Nagisa!" a familiar and cheerful voice called out. Nagisa looked up to see a young teenage girl standing in front of the old E-class building. She had longer hair than Nagisa remembered, but it was still colored bright green and her eyes shone in the sun light. She had a big smile on her face and she, herself, was basically shining.

"Kayano!" Nagisa said, happily smiling. The two hugged each other tightly. "It's good to see you. How have you been?"

"Well enough", Kayano answered, smiling even wider. "I mean, I've been studying to become an actress, but it's hard, alright! But still fun!"

"That sounds interesting", Nagisa nodded. "Want to tell more?"

"Of course I do!" Kayano said. "But let's go inside already, it's burning hot here and we finally have an air-conditioner! You're the last one to arrive by the way, Nagisa. Everyone's already waiting."

Kayano sounded so happy and cheerful, it was like she wouldn't have faced anything bad in her life before. Of course, that wasn't the truth, she had been through more than a normal grown-up adult would in her/his whole life. After all, learning to become an assassin and seeing your older sister die in front of you wasn't everyday life.

Nagisa was glad to see, that his old friend was still holding on to a certain amount of innocent behaving. Kayano wasn't a bad girl, to put it correctly. She was a good student now days, and a good actor. But yet again, she had always been a good actor.

Nagisa himself had left right after the graduation from junior-high. He had left with his mother to Tokyo and started to study to become a teacher. He had left the old school behind, as well as his friends. He had ran away, because of the guilt he felt.

Kayano dragged him inside and they came right in to the classroom when the others started to shoot at Koro-sensei. It looked so much like two years ago, that Nagisa had to stop to watch. He had missed this, yet he hadn't had the will to kill his sensei. Now, the yellow octopus was dodging the bullets easily, like he always had. He also had a big creepy smile on his face - like always.

Nagisa smiled at the sigh and suddenly everyone stopped. They turned to look at him and Kayano who had just stepped inside with Nagisa. Koro-sensei turned his head around as well.

"Ah, Nagisa-kun", he said. "It's nice to see you again."

"You as well, sensei", Nagisa answered. "If I've heard correctly, you're now teaching in the main campus."

"Yes, indeed", Koro-sensei nodded. "You see, Asano-kun changed the school system after his father left. He is now the head of the school, even tho his still basically a student. He is quite wise, maybe even wiser than I am."

"It's hard to believe into that", Nagisa said.

"Nagisa!" Nakamura yelled. "It's good to see you!" Suddenly there was over ten students jumping on him, hugging him, hitting his back in a gently way and yelling at him. They weren't angry, alright, but they were little too energetic.

Soon, Karasuma-sensei and Bitch-sensei came in as well. Nagisa heard that Bitch-sensei was working with Karasuma-sensei in the ministry of defense in now days, as his personal assistant. They were a good pair - in love and in work. Nagisa wasn't entirely sure, that did Karasuma-sensei return Bitch-sensei's feelings, but at least they seemed closer than before. Oh, and Bitch-sensei wasn't an assassin anymore, which was good news.

"Hello, everyone", Karasuma-sensei said politely. "Looks like you've all grown up."

"Aw, my little students", Bitch-sensei said, tears in her eyes. "You're all so big and all… adult like!"

"They aren't adults yet", Koro-sensei pointed out. "But next year, you'll all be eighteen."

"True!" Maehara said, smiling. "And then I can finally buy a real car and drink as much as I want!"

"Don't be stupid", Nakamura said to that. "If you drink too much, you'll become like Bitch-sensei."

"Excuse me, you little brat?!" Bitch-sensei yelled, already getting annoyed. "We're having a meeting after two years, and you're already mocking me?! And would you stop calling me 'bitch'?! My name is Irina!"

"But to us, you'll always be Bitch-sensei", Maehara stated, laughing. Soon everyone else joined him.

Seriously, it's like nothing would've changed, Nagisa thought, smiling himself. I just wish you'd be here, Karma.

**Ansatsu Kyoushitsu**The Island arc**

The bartender's pov:

The ship would leave in two days, and they would finally return to the island of criminals. It was a big business around Japan, criminals from all around the world would come to visit the island. The island was big and far away from the trouble of the world. And only criminals were allowed to come there.

Exception being assassin. They weren't welcome.

The bartender sighed as he poured another glass of beer for some ugly man, who smoked weed like his life would've depended on it. The ship wasn't so pleasant when it wasn't at sea. Everyone was more classy when they were going or coming back from the island. In the island, everything was classy.

He said nothing as the man paid and left with his beer, leaving him alone and in peace. He started cleaning the tables, leaving his pose. To the island came families and loners, it didn't matter really. If they paid and behaved, they were welcomed with warm hands.

It was a strange rule. No killing and no fighting. They were all criminals, why weren't they allowed to fight and steal and do other things criminals did?

Maybe, the reason was the fact, that every criminal wanted to be a normal person in a while, enjoying life of a rich man.

Luckily, the man who had created the criminal island, had something to do with Japan's most well-known men and he made sure that no cop would ever find out about it. No, many probably knew already, but what could they do? Nothing, if you would ask from the bartender.

He himself had worked there for about a year now, and he was getting full of it. He was quitting the job soon, probably after this summer. He did get lot of money out of the job, he had the good looks and women came to him easily, paying lots of tips. And all of the people here were rich.

But most of the workers in the ship were just slaves, and so were the ones in the island as well. He himself was one of those who had come for their own free will. Still he hated the place. Everyone was so greedy for money, attention… and sex.

Either way, his master's orders where simple. Do you job as a bartender. Entertain the customers, anyway possible. And he had meant every word he had said.

The bartender turned around and went back to his pose as a new customer closed in. He took the orders silently like he always did and earned some tips. It was a woman of course, a woman who had come to him to get pleasure. But the bartender didn't want it.

He never did. The bartender wasn't some kind of playboy, who was with women one night and dumped them after that. Most of his co-workers did anything to get more money. So they could get out.

Now then, back to the present problem. How could he run away this time? What kind of excuse could he make up now? His friend and co-worker wasn't even close by, she would've certainly figured some kind of excuse for him.

Just great, he thought as he took the money from the older woman. How did I get stuck here?

**Ansatsu Kyoushitsu**The Island arc**

Nagisa's pov:

They talked into the late night, and when the clock was finally eleven, they started to make their beds. Koro-sensei had cleaned the building yesterday so every place was clean and looked new. They could sleep everywhere. Of course, the girls slept in an another room with Bitch-sensei, and the boys in the other. Only Karasuma-sensei and Koro-sensei got their own rooms.

It was half past eleven when all of the former students and teachers gathered around again, in the boys bedroom. They weren't done talking. And Nagisa had yet to tell what he had seen in the port, he had yet to tell about Karma being alive.

Probably. He was probably alive.

"So, has anyone heard of Karma-kun?" Okuda-san asked suddenly. The question surprised everyone and an awkward silence fell into the room. No one said anything, no one knew about the red head.

"He's dead, right?" Terasaka-kun said suddenly, after a while. "He has to be, he was pierced by a tentacle, no one survives that."

That was true. Karma-kun had been pierced. Impaled when he had protected Kayano and Nagisa from the second God of Death. So, Nagisa wasn't the only one feeling guilty, Kayano had to felt some kind of illness in her, every time someone brought their friend up.

"Actually", Nagisa said, getting everyone's attention. "I think I've got something new on him."

"What do you mean?" Bitch-sensei asked. "Is he alive?"

Nagisa nodded. "I saw him, today. At the port."

"WHAT?" the whole class practically screamed, only Karasuma-sensei and Koro-sensei staying quiet. And then, the whole room was filled with voices, and questions were thrown at Nagisa with great speed. He couldn't answer any of them. Kayano just stared at him, concern in her eyes.

"Everyone, quiet down!" Isogai-kun yelled, and surprisingly, everyone did shut up. "Now, Nagisa-kun. Please explain."

Nagisa nodded again and started talking. "I bumped into him while I was walking here. I swear, even though I only saw him for a second, it was Karma. He had grown alright, but there was no mistaking from his red hair and golden eyes. No one else has eyes like that or hair as red as his was. It has to be him."

"Did you talk with him?" Kayano asked.

This time, Nagisa shook his head. "No, he didn't even stop to apologize for bumping into me. He only glanced at me, and I don't think he recognized me. I mean, I've cut my hair and all."

"So, we can't be sure it was actually him", Itona-kun stated.

"Yes, we can!" Nagisa said to that. He knew that he had seen Karma, he swore he had. The hesitation from before was completely gone. He knew. "It was him, and I know it!"

"Your mind could be just playing with you", Terasaka snorted. "You just miss him, and thought that you bumped into him while coming back here. We all know that you feel guilty."

The class was quiet again.

Then, Koro-sensei opened his mouth for the first time. "I believe in you, Nagisa-kun. There's no lie in your eyes. But, to be sure, let's go to the port tomorrow, and see, if we can find him."

Everyone agreed to that, and so, they went to sleep.

**Ansatsu Kyoushitsu**The Island arc**

So, in the morning, everyone prepared to leave to the port. There was a awkward silence between all of them, Nagisa knew that most of them still doubted him. Kayano, Koro-sensei and Sugino-kun were probably the only ones who believed in him.

"We'll walk to the port", Karasuma-sensei said. "...And, just be normal."

"Right", the class nodded to that. The air was still filled with mixed feelings about this. Nagisa could sense Terasaka's disapproval and Okuda-san's hopefulness. Nagisa swallowed and wished that his eyes really hadn't just tricked him.

They walked slowly towards the port, everyone had scattered in their own little groups. Well, it was basically the same as always. Nagisa himself was with Koro-sensei, Kayano, Okuda, Sugino and Kanzaki.

"What if we really meet Karma-kun?" Kayano asked, worry in her voice. She had guilt written all over her face, Nagisa knew that she still blamed herself for Karma's "death". "What are we going to say to him?"

"I don't know", Sugino-kun muttered. "Maybe we should ask him to join us for this summer. At least, we have to talk with him."

"Yeah", Kanzaki-san nodded. "I want to know where and why he disappeared."

"To that, I think we all can agree", Koro-sensei hummed, a thoughtful look on his face. "Let's just hope he isn't mad or anything like that."

"Indeed", Nagisa said, smiling a little. Karma had been the strongest in their class, he had a strong mind and he had been physically the strongest as well, even if Terasaka seemed to be the most muscular. "I wouldn't want to face his anger when we meet for the first time in two years."

Nagisa didn't know, that had he really ever seen the red head actually angry. One time, though, Karasuma-sensei had to stop their practice fight, because Karma-kun had gotten little too into it, after Terasaka-kun had mocked him and his family. In that moment, the red head had snapped for some reason, and their were lucky Karasuma-sensei was there.

Otherwise, Terasaka would be dead now.

Nagisa shivered as he remembered the eyes Karma had had that day. So empty and cold, but still very determined. No fear in them, no emotion. He hadn't smiled. Karma had been very serious looking, even scary serious. Nagisa never wanted to see that side of him again - that was the side of Karma, that made him so fearful. When they had their little fight, he had seen a glimpse of that side again, and it wasn't fun. And, if Karma wouldn't have suddenly given up, Nagisa certainly would've lost. The moment when Karma dropped his mask for a second, and showed the demon behind it. Nagisa had frozen completely, so scared he had been.

That was the moment Nagisa also realized that he could never be an assassin, not truly.

He didn't have what it took to kill. Karma again, he did.

They finally came to the port, and it was really crowded place. It was Saturday after all, and many ships would be leaving. And coming.

Nagisa noticed something different in the port almost right away. At the end of the wharf, there was big luxury ship, all alone. No one came close to it, even though it seemed to be a fairly new and all the lights on the ship were on. There were also some men running around the deck. But, because the ship was left alone, everyone would notice it. Maybe the ship had just come and was now being prepared for an another trip. Still, it woke Nagisa's suspicion.

"What's with that ship?" Kayano asked, before Nagisa himself could say anything. "Why is it all alone? And I'm getting strange feeling of it, it's like it would let out some strange bloodlust."

"Ships can't do that, they aren't living creatures", Terasaka snorted.

"Maybe the ship can't", Nagisa said. "But what about the people inside of it?"

Karasuma-sensei coughed and everyone turned to look at him, waiting for him to say something. He seemed very serious suddenly.

"Let's go to the cafeteria close by", he said. "I have something to tell you, about that ship I mean."

"Like what?" Maehara asked.

"We'll talk in the cafeteria", Karasuma-sensei answered. "But let's just say, that me and Irina aren't here just for fun."

"So, you've got some kind of mission?" Nakamura asked.

"To the cafeteria", Bitch-sensei commanded. Everyone was now curious, even Koro-sensei, so they all did what they had been told to do.

In the small cafeteria, they took the place in the corner and everyone gathered around Karasuma-sensei. The workers in the cafeteria looked at them, some angry and some curious. But they left them in their own peace, only bringing them some water. No one actually dared to come closer, because… well, let's just say that Koro-sensei was definitely creepy - especially in his disguise.

"Have you heard of the Criminal Island?" Bitch-sensei asked.

Kanzaki nodded right away. "I heard some rumors about it. They say it's an island in middle of nowhere, and only criminals are allowed to go there. The thing is, police can't do anything to stop them from going there, because they haven't found the island and the owner is involved with Japan's most influential men", she said.

"An island for criminals?" Isogai asked. "For what reason?"

"It's like a paradise island", Karasuma-sensei told them. "If you're rich enough, you can go there for a vacation. Criminals all around the world go there. Out there, you don't have to worry about cops and any other criminal world worriers. Even we, the defense ministry, don't have much of knowledge on the island."

"So, why are you worried?" Maehara asked. "If they don't do anything bad, why worry?"

"It's not that simple", Bitch-sensei said. "They have unlicensed casino's there, and gambling places, that aren't excepted by the police. But the biggest problem is the slavery there."

"What?" Sugino-kun yelped. "Slavery? Do they keep slaves there?!"

"Please, don't yell, Sugino-kun", Karasuma-sensei said. Sugino swallowed and looked around nervously. Luckily, no one seemed to pay anymore attention to them.

"And yes, they have slaves around there", Karasuma-sensei continued. He had crossed his arms on his chest and was looking very angry now. "It's disgusting, really. They gather people all around the world and make them work for them against their own will. And some of them get beaten up - even killed, if they don't do their job well. And that's when we come in."

"We?" Nagisa asked.

Karasuma-sensei nodded. "The ministry of defense has assigned me and Irina to investigate the Criminal Island, and possibly, save the slaves. The ship you saw in the port is the one who takes the criminals to the island. It's the only one in the world. And it's very well secured, it took over half year for us to get the tickets for the island. And, finally tomorrow, we'll be leaving with the ship."

"WE?!" the whole class was now questioning.

"You guys are coming with us", Bitch-sensei stated.

"WHAT?!"

"NOT GOING TO HAPPEN!"

"I'M NOT GOING TO GET MYSELF KILLED BECAUSE OF THE MINISTRY OF DEFENSE!"

"Everyone, calm down", Koro-sensei said. He was staying unusually calm. "Think about the slaves there, they could be desperate for help. We should go, after all, we know how to defend ourselves."

"Assassins aren't allowed to the island", Karasuma-sensei bluntly said.

"Then why are you asking us to come along?" Kayano asked.

"Because you're wise and you know how to defend yourselves - just like Koro-sensei here said", Bitch-sensei said. She too, was very calm and professional. "C'mon, you can spend your whole summer in a paradise island without paying for it. All we have to do is act like we would be criminals and stay low. Easy."

"I still don't like this", Kanzaki muttered.

"It does sound very dangerous", Isogai nodded. Many agreed.

"We were supposed to come and look for Karma", Nagisa pointed out. "Not leave for some trip."

"We have still time", Karasuma-sensei nodded. "We'll leave tomorrow morning, and that's final."

"So, we can't say no?" Nakamura asked.

Karasuma-sensei glanced at her, and yeah, that was it. No one dared to say anything against it anymore.

"Now, class", Koro-sensei said, smiling again. "Think it the way Irina-sensei said. We're going to a paradise island for free, and we can help other people at the same time. Doesn't it sound good?"

"That's true", Maehara nodded. "Some action could be fun."

"Yeah", Kayano said. "Why not?"

The class seemed to forget about the dangers of this trip and everyone started excitedly make plans for the vacation. Swimming, eating, sleeping, shopping, playing around… They could do anything on the island. At least, if Bitch-sensei was telling the truth.

Nagisa glanced at Karasuma-sensei who observed them carefully, little smile on is face as well. He seemed to be happy to see, that the class agreed to come along. Nagisa sighed in relief, he himself had been ready to go in the moment Karasuma-sensei had brought the whole island thing up. He was ready to help other people.

Still, this thing meant, that Karma was getting left behind. Nagisa was quite sure that Karma didn't have a ticket for the trip.

He looked outside of the window, just in time to see a familiar person. There was a tall young man, walking towards the cafeteria. His hair was fiery red and his eyes glimmered in gold. Strange thing, he was dressed like a bartender and he had no smile on his face. His face seemed empty and emotionless.

But it was definitely him.

Nagisa stood up in the second he saw the red head. He had expected for the boy to come to the cafeteria, but he was wrong. The familiar person stopped right in front of the cafeteria, not seeing Nagisa or the others.

What was he waiting for?

Then suddenly, a silver haired woman stepped out of the cafeteria and she walked to the red head. She said something, but the young man didn't answer. Nagisa just stared, even though, he should've walked to the familiar person and stopped him from leaving as he left with the woman.

"Nagisa", Kayano said. "Where are you looking at?"

Nagisa didn't answer, as he quickly ran out and looked around. Kayano came out right after him and she too, saw the red head, who was walking away slowly.

"Is tha-", Kayano was cut off by Nagisa's sudden yell.

"Karma!"

The red head stopped for a moment, and Nagisa knew he had been right. It was him, it really was Karma.

The boy turned his head around, and looked at Nagisa and Kayano for a second. His eyes were wide in surprise. They stared at each other for a while.

"It really is him", Kayano whispered as the others came out. No one said anything as Nagisa and Karma stared at each other. But the spell was broken when Karma turned his head away and disappeared behind the next corner with the silver haired woman.

No one ran after him.

But why?

Why didn't anyone go after him?
