Chapter 4

Nagisa's pov:

Why did it feel like the trip to the house was so damn long?

Nagisa checked the clock every now and then, but it seemed that the clock wasn't moving at all. He checked the clock at 12.16, and then he waited like five minutes (really for a minute) and checked the clock again - only to see that the clock was 12.17. And Karasuma-sensei had told them, that the trip to the house would take at least two hours.

It had only been half an hour, and Nagisa was already wishing that he would've stayed home. He wanted peace and quietness, and he certainly wasn't getting it here.

People around him were talking again with loud voices, forgetting the nervous atmosphere. Nagisa was quiet and Kayano slept. She was leaning against his shoulder, snoring quietly. Nagisa didn't mind at all, as long as Kayano didn't start snoring too loudly.

He looked at Karma, who was staring out of the window, no emotion on his face. His red head was little messy and the slight breeze didn't make it any better. But it wasn't like messy hair would make Karma look any worse - seriously, the guy was like a model.

Nagisa turned slowly to look at the two silver headed servants, who sat close by Karma. Kasumi was talking with Hiro with a low voice, obviously lecturing the younger boy about something. Nagisa noticed, that she seemed little more relaxed around Hiro and lot more nicer.

She patted Hiro on the head, smiling brightly. Hiro blushed slightly and slapped Kasumi's hand away. Nagisa had to wonder what the two were talking about. Kasumi was behaving like she would be Hiro's older sister, with her caring and commanding - yet kind and warm - attitude.

Nagisa realized, that it was very possible that Hiro was Kasumi's younger brother. They did look a like - the same silver hair and pale skin. Only, Hiro was shorter, he was a boy and his eyes were light grey. Kasumi's eyes were dark blue.

Nagisa watched them carefully, observing their every movement. He didn't see anything out of the ordinary, they behaved like normal people. Like normal siblings. Then Kasumi turned her head at Karma and said something, still smiling brightly. Karma nodded slightly at her and Kasumi kept talking. Watching the two, Nagisa noticed how strong bond they seemed to have. Karma didn't need to talk for Kasumi to understand him and Kasumi accepted his silent.

They had probably worked together for a while now.

Maybe Kasumi would know why Karma doesn't talk, Nagisa thought. And maybe she knows the reason he's here.

He kept watching the three servants the whole trip to the house. He noticed that Hiro had the habit of spacing out now and then, and Kasumi smiled a lot and she didn't fake it when she was around the two boys. Karma again always just listened, sometimes shaking or nodding his head - he even smiled slightly once.

Nagisa realized for the first time how much he had missed the smile. Karma used to smile a lot when they were still in the junior-high. Nagisa had noticed that sometimes the smile was forced, but when Karma truly smiled, he felt warmth in his chest and he wanted see him more like that. Happy. Carefree.

The small smile Karma made in the bus was nothing like in the past - but it was a real one. Nagisa assumed that he didn't smile a lot now days. That made him feel little sad.

"Hey little guy!" Terasaka's sudden yell woke Nagisa's attention. The brown headed boy was talking to Hiro, the bad thing happened to be that Terasaka sat four seats behind the silver haired boy - and so, he had to yell. Everyone in the bus quieted down.

Hiro turned to look at Terasaka, his eyes dull. "Yes?" he asked, as politely as he could (failing with his cold voice). He wasn't really good at acting happy.

"How come you're working here?" Terasaka-kun asked. "You look like you would be ten!"

Hiro frowned. "I'm twelve."

"Yeah, whatever. But why are you here?"

"Because I work here."

Hiro and Terasaka stared at each other, the other pissed off and the other looking like he didn't get were Terasaka was going. Hiro's grey eyes were empty, and he had no smile on his face, but somehow Nagisa got the feeling that the boy was mocking Terasaka. Hiro seemed very serious, but at the same time he seemed like he would be just playing with them.

He was another kind of devil, right next to Kasumi and Karma. Nagisa started to realize, that around the three was a strange aura. The aura was like a silent agreement, everyone of them seemed to play a role. A role that Nagisa couldn't figure out - he had no idea who these three really were.

Hiro and Terasaka continued their silent argument, Kasumi and Karma watching - observing - it. Nagisa looked at Karma's cold eyes, and at the moment, he truly realized that the old Karma was gone.

He felt like the real Karma would be somewhere sleeping - no, lost. And Nagisa had to find a way to find the person he had known.

He would find the real Karma Akabane.

**Ansatsu Kyoushitsu**The Island arc**

Finally the bus stopped in front of a huge house, it looked like a mansion. The house was beautiful white and there were three floors - probably a cellar and an attic as well. The front yard was huge. The grass was green and Nagisa saw many different flowers. There were even few sakura-trees growing in the yard. Everything seemed perfect, maybe even little too perfect. He could hear the sea behind the house. Nagisa took a deep breath in - he enjoyed the warm breeze that blew against his face. It had a little salty and wet taste.

Bitch-sensei had been right, the island seemed like a paradise.

They lifted their package out of the bus and Karasuma-sensei ordered them to take everything inside, to Kasumi's surprise. The silver haired woman asked Karasuma, that wasn't it their job, but the raven haired man just shook his head.

"You don't have to do everything here", he said.

Kasumi was left dumfounded, and she stared at Karasuma-sensei's back as the raven haired man walked inside. Nagisa smiled a little, but his smile disappeared quickly, as he noticed the red head standing right next to him. Kayano was leaning on Nagisa, so he was having hard time with his and Kayano's package. The green haired girl wasn't completely awake and she wouldn't move on her own.

And Nagisa couldn't get their packages inside because of her.

"What is it?" he asked from Karma, who stared at down at him. Of course the red head didn't answer, but he gave him his hand. Nagisa quickly understood that he wanted to help him with his little trouble.

"No need for that", Nagisa said, pulling a smile on his face. "Kayano will be awake soon. See, - she's standing already."

Karma blinked his eyes and tilted his head to the left. He looked little confused - probably because Kayano didn't seem awake at all. Then the red head smiled a little, it was a small smile, but a warm one. Nagisa couldn't help but blush a little.

"Seriously, I'll be just fine", he mumbled, gaze at the ground.

"Let him help", Hiro said. The shorter silver haired boy was holding on to his and Karma's bags, a bored look on his face. "It'll be quicker that way."

Nagisa had to agree with the boy, so he let Karma help him. The red head lifted the two bags easily and led the way to the house. Kasumi had gone to open the door and she was already gone somewhere when they stepped inside.

"Whoa!" Kayano was finally fully awake, staring at the high ceiling. The house was even more amazing from the inside. The ceiling was up high and there were expensive looking carpets on the floor. The floor itself was smooth and brown wood, but not even the little bit slippery.

Nagisa could see the stairs from the door, and there were already few of his friends climbing on them with their bags. Kasumi was discussing something with Karasuma-sensei. Bitch-sensei and Koro-sensei were on the second floor, splitting students into two-man groups.

"Nagisa, you'll be with me!" he heard Sugino yell. The raven haired boy was also already on the second floor, waving at him. "Come on!"

Kayano took her bag and left to Okuda-san, who was her roommate. Nagisa took his bag and bowed his head a little. "Thank you for helping me", he said to the red head who was still standing in the doorway.

Karma nodded a little and looked down at the floor. He was obviously not used to getting any thanks. Nagisa would make sure to thank him every time the red head would do something for him.

He wanted to make sure that Karma knew, that he appreciated his help.

**Ansatsu Kyoushitsu**The Island arc**

Koro-sensei's pov:

It was around two o'clock when he felt a good smell coming out of the kitchen. He was all the way in his room and could still smell it - a smell of gourmet food. Ah, it smelled really nice.

Koro-sensei got up and sneaked downstairs. Karasuma-sensei was outside with the students and Irina-sensei, while Hiro was keeping an eye at them and Karma and Kasumi were making food at the kitchen. Honestly, Koro-sensei hadn't guessed, that the red head was actually good at cooking, but maybe he was wrong.

The smell at least was heavenly.

He crossed the living room, that was huge - partly because it was also the place they would eat. There was two huge tables, so everyone could sit. The tables were already filled with different kind of salads and breads. The bread smelled excellent, it was still warm.

Koro-sensei would've wanted to taste it, but the smell coming from the kitchen was even better. He quietly walked past the living room, and stopped at the doorway to the huge kitchen. He heard Kasumi's silent talking and then someone opened the fridge.

"The dessert should be done now", he heard Kasumi say. "Would you make the sauce for the main course?"

Koro-sensei heard no answer, but he was sure that Karma was doing what Kasumi had asked for. He then decided to show himself. And it wasn't the best idea - a yellow octopus appearing suddenly, a hungry look on his face, was more than enough to scare the poor little silver haired girl.

Kasumi let out a surprised scream, but the red head just stared at him. He didn't look the bit surprised. And just then, Koro-sensei remembered that he had forgotten to put on his disguise. Now, Kasumi and Karma saw what he truly looked like.

Suddenly Hiro was standing behind him. Koro-sensei was surprised how quietly the boy moved - getting behind him without him noticing was something new. The boy froze as he saw him.

"Wha- what the hell?" was the first thing coming out of his mouth. Soon enough, Karasuma-sensei, Irina-sensei and the whole class was standing outside the kitchen. Koro-sensei saw Karasuma-sensei facepalming and Irina-sensei sighed loudly.

"Umn", Koro-sensei coughed. "How should I explain this? Does anyone have any ideas?"

Instead of answering, the whole class started laughing. Hiro, Karma and Kasumi were all just watching quietly, too dumfounded to say anything. Well, Koro-sensei couldn't blame them. Karasuma-sensei took the situation under his control quickly.

"As you can see", he said. "Our friend and co-worker here had a little accident few years ago. He was trying some new chemical… things, and he… well, he failed. And now he looks like this."

The class was still laughing.

"Not only that", Irina-sensei continued, nervous look on her face. "He can move very fast - no, he's the fastest person in the world. And he's the one who blew up the moon few years ago."

"You?!" Hiro asked.

Kasumi seemed to get her voice back. "Hiro, please behave!" she said. The silver haired girl walked past Koro-sensei and kneeled in front of the silver haired boy. She whispered something to him, in other language, that Koro-sensei and Irina-sensei weren't able to understand. Soon the boy bowed his head in apologize.

"Sorry for being rude", Hiro muttered.

"Not at all", Koro-sensei said, smiling as kindly as he could. "I know I probably look very weird, but don't worry, I wont hurt any of you."

Hiro mumbled something Koro-sensei couldn't quite catch, but Kasumi could. The silver haired girl hissed the boy to shut up - with different language of course, but Koro-sensei didn't need to know the language to understand those words.

"Koro-sensei isn't a bad person", Nagisa said. "Believe me, he may look scary, but once you got to know him, he's the kindest person you'll ever meet."

"Kindest criminal", Karasuma-sensei sighed. "And that's way he sucks at his job. He's too kind."

Nagisa sweat dropped. "Yeah, that too."

And Koro-sensei laughed.

**Ansatsu Kyoushitsu**The Island arc**

The meal was amazing, the best one Koro-sensei had ever had. And he had eaten a lot - he had tasted food from French to Thailand, Russia to America - and he had never tasted anything good as this. He and the others ate a lot, but the best part was definitely the dessert.

After the meal, Kasumi and Karma cleaned the table as Hiro disappeared to the cellar. He said something about trees and fireplace.

"Do you need any help?" Koro-sensei asked from the red head, who was washing the dishes. Karma shook his head slightly, and Koro-sensei didn't try to push it any futher.

Koro-sensei went outside and sighed. He had many thoughts in his mind at the moment. First of all, he had accidentally exposed himself to normal people - even his new class at the Kunugigaoka junior-high didn't know who he really was. They didn't know his true form. He had wanted to show them - but the ministry of defense disagreed and they decided to keep his true form as a secret. Even tho, Koro-sensei wasn't a danger anymore, the ministry of defense wanted to keep an eye at him. Karasuma-sensei had tried his best to convince them, that the yellow octopus was no harm to them - but guess it was hard to believe him, because Koro-sensei had blown the moon up.

Well, at least assassins didn't try to kill him anymore - the ministry of defense had pulled the bounty of.

The second thing that Koro-sensei couldn't shake off of his mind, was Karma's reaction when they had seen his true form. The red head hadn't been the slightest bit surprised and Koro-sensei had to suspect, that maybe the red head did remember them. But then, why would he act like he didn't?

They were there to help them, yet it seemed like neither of them wanted help.

Oh well, Koro-sensei thought. We just have to wait and see what happens. Let's just hope that it wont take long.

He stared at the beautiful sunny sky and sighed again. The students had left with Karasuma-sensei to explore the island, if Koro-sensei had heard correctly, they wouldn't be back until ten pm. So, he and Irina-sensei were alone with three servants.

"Is something wrong, sir?" Kasumi voice asked behind him. The silver haired girl was standing in the doorway

Koro-sensei's hearth skipped a beat. How didn't I sense her? First Hiro and now Kasumi - something was wrong with these servants. They moved strangely quietly and left nothing behind. What was even more strange, Koro-sensei couldn't smell her at all. Sure, now he could sense her fresh ocean-like smell, but not before.

"Sir?" Kasumi asked again, looking at him concerned look in her eyes.

Koro-sensei snapped out of his thoughts. "Nothing is wrong, dear. I was just thinking, nothing more."

Kasumi smiled brightly. "That's good to hear", she said. "If you don't mind, I'll be going now."

But before she could go, Koro-sensei gently stopped her with his tentacle. "Actually Kasumi-san, I'd like to ask you few things."

The silver haired girl stopped and looked at the yellow octopus for a moment, before nodding. "Of course sir, go ahead."

"Is Hiro your younger brother?" he asked.

"Yes, how come?"

"It's nothing, I was just wondering, why would you two come here? Are you criminals?"

"We? No, of course not", Kasumi answered, looking little uncomfortable. "We just have lot of experience of being around criminals. And bad things don't trouble us as much as normal people."

"Bad things?"

"Fights and death… criminals and their little games", Kasumi explained. "It's complicated."

"I see", Koro-sensei nodded. He saw how uncomfortable this made Kasumi, so he decided to leave it there. "There's one more thing I wanted to ask you. Both you and Hiro were very surprised when you saw how I really look. So, why didn't Karma-kun seem the least surprised?"

"Karma?" Kasumi sweat dropped. "You probably know that he is little different, because he doesn't talk. Well, that is one of the reasons why he is capable of observing people so well. He can tell things that other guards in this island can't. When it comes to you… I just think, that he saw right through your disguise. And, Karma doesn't get surprised easily."

"Hmmn, that's interesting. If he's so good at observing others, shouldn't he be working with the guards?" Koro-sensei asked.

"That's what I thought at first as well", Kasumi said. "But he doesn't really care for that job. And I don't really care why he didn't become a guard - it's quite important for me and Hiro that he stays with us."

"You three seem pretty close."

Kasumi nodded, a distant look in her eyes. She had a small smile on her lips and Koro-sensei could tell that this time, it was a real one as well. "In this island - no, because of this job - we quickly learn the importance of having people around you. It means a lot to have a friend - even if there's only one."

Koro-sensei smiled warmly. "Indeed."

They stood there for a while, both quiet. The warm breeze felt nice against Koro-sensei's face and he just wanted to melt there.

"It's beautiful here, isn't it?" Kasumi asked.

Koro-sensei stared at the beach in front of him. The water was beautiful turquoise and the sand smooth and warm. The sun was still high in the sky, lighting up the ocean. Kasumi's eyes shined in the light, making her look even more beautiful than she was.

"It's probably the prettiest place I've ever been", Koro-sensei answered. Kasumi looked at him, still smiling.

"It's funny how a place full of bad people can still be so beautiful", the silver haired girl whispered. Her voice was filled with sadness and her eyes mirrored her feelings. Deep blue eyes filled with so much sadness - Koro-sensei could never understand why this girl was so sad.

Kasumi smiled soon enough, hr smile being fake now. "I'm sorry sir", she said. "I shouldn't say things like this."

"It's okay", Koro-sensei said. "Just don't talk about this to Karasuma-san, he will get pissed. I don't care if you think us as bad persons, so don't be afraid. Let's just keep this as a secret."

Kasumi chuckled a little. "Whatever you say, sir."

**Ansatsu Kyoushitsu**The Island arc*'

Nagisa's pov:

When they came back to the house, there was some warm food waiting for them. Nagisa was happy to see that, he was quite hungry. Kasumi had made them some lunch for their little journey. They had seen amazing things like new species of birds, flowers and some bugs. They saw small waterfalls and many different plants. They had walked over 5 miles (probably) and finally sitting down felt amazing.

"Ah, I'm so done for tonight", Maehara-kun sighed as he sat down to the couch. Other students sat down as well, everyone complaining about their feet and how tired they were.

"This is new", Karasuma-sensei said. "Your shape is worse than two years ago. I think we should train to make it better."

"Didn't we come here to chill?" Nakamura-san asked.

"Yes, but it'll be boring if we wont do something", Karasuma-sensei said. "Don't worry, we'll start loosely."

"Right", the whole class mumbled as an answer. Then they moved to the tables and started eating.

Nagisa had been happily surprised about the fact, that both Kasumi and Karma could cook. The meal before had been amazing, and even if this one was lighter, it was still good.

After the meal, everyone gathered outside, at the backyard. Few of the students went swimming, because the water was still warm. Nagisa himself stayed at the beach, and talked with Sugino and Koro-sensei.

"How was your day, Koro-sensei? Was it boring?" Sugino-kun asked after Nagisa and he had finished telling their former teacher about their day.

"It wasn't the least bit boring", Koro-sensei answered, a big smile on his face (as usual). "I had a long talk with Kasumi-san, and it was quite interesting. She even made some pudding for me after we finished talking. It was delicious!"

"I can imagine", Nagisa nodded. "She's a good cook."

"Yeah", Sugino said. "Do you think any of the three can play some instrument? It would be nice to hear some music. It's boring to just lay down."

"You don't know how to relax, Sugino-kun", Nagisa laughed. "But yeah, music would be nice. Should we ask from Bitch-sensei, she does know how to play piano."

"She seems way too drunk to play anything", Sugino-kun pointed out. Nagisa and Koro-sensei looked at the blonde teacher who was leaning on Karasuma-sensei and laughing hysterically.

"True", Nagisa chuckled. "Then, go ahead and ask from Kasumi."

Kasumi was sitting at the terrace with Hiro, but Karma was inside doing whatever the servants usually did on their free time. Sugino stood up slowly, little hesitation in his eyes.

"Are you scared to talk with her?" Kayano asked. The green haired girl had just come back from swimming and sat down next to Nagisa. "She seems nice enough - don't be scared."

Sugino blushed. "I'm not scared! I just haven't ever talked with someone so… beautiful and strong. And have you realized what kind of aura she has?"

"What do you mean?" Nagisa asked.

"We've met assassins, and we know how the atmosphere around them feels like. It's dark and filled with bloodlust. Then there are normal people, whose aura is like… well, normal", Sugino-kun explained. "But with these three, I can never tell what their up to. And Kasumi… she is like the one controlling everything. Karma and Hiro. Even us."

Nagisa shared worried looks with Kayano.

"Very good observing, Sugino-kun", Koro-sensei nodded. "But, humans are different. This doesn't mean anything. But let's just keep on eye at them, sooner or later, we'll find out their secrets."

Sugino nodded and then he left to talk with Kasumi. The silver haired girl smiled at him right away and they talked quietly for a moment. Then Hiro got up and left inside and Sugino came back with Kasumi.

"Kasumi-san told me that she can play the piano and Karma can play basically anything", Sugino told them. "Can you believe it? I never thought that Karma was a musician."

Soon, Hiro and Karma appeared at the door, Hiro was holding onto a violin and Karma was looking troubled.

"Karma can play some music for you, if you want", Kasumi said. "He's good at it, believe me. You'll love every moment of his play, once he starts."

"He doesn't look like he would want to play anything for us", Kayano said. The red head did look like he would gladly instead stay inside and keep washing the dishes for the whole night.

"He'll play, if you ask." Kasumi was smiling at them, looking very convincing. Nagisa sighed and walked to Karma and Hiro.

"Would you please play some music for us? Kasumi told us that your good", he asked. "I'd like to hear you play."

Karma stared him for a moment, before letting out a sigh. Nagisa knew that he had won and it made him grin.

"Thanks!"

Hiro gave the violin to Karma and gave him some space. The red head tested was the violin in tune and then turned his attention back to Nagisa.

"He wants to know what kind of song would you like to hear", Kasumi said, standing suddenly right behind him. Nagisa jumped a little. This girl… what's with her? Something in Kasumi made Nagisa think a certain assassin, the Shinigami. One thing was for sure - Kasumi was no ordinary servant.

"Um… just play something nice", Nagisa said.

Karma's face was a one huge question mark.

Kasumi and Hiro both chuckled.

"If you don't mind, Nagisa-sama", Kasumi said. "I know a good song that he knows how to play."

"That's good", Nagisa smiled.

Kasumi walked to Karma and whispered something to his ear. The red head thought it for a moment, but lifted the violin soon enough.

The song started out quietly, and had a very sad tune on it. It didn't really change, the sound just got little stronger. It didn't feel special - not at first. But soon Nagisa felt like the time would've stopped, like everything in the world would've stopped to listen Karma's play. He noticed how relaxed the red head looked when he played the violin - he looked like he would enjoy it. Happy.

Karma looked happy.

It was truly something to watch. As the different sound left the violin, getting everyone's attention, Nagisa took everything in. He didn't close his eyes, he just stared at Karma, admiring everything. It felt like the red head would be only playing for him and all his attention was at Karma. Nagisa could've listened to it for hours without getting tired of it.

But all good things come to an end, sooner or later.
