TITLE: 殺せない

SUMMARY: "I'm an assassin, the best one alive today. I was hired by, well, it's bad taste to reveal your employer. So let's just say there is a hit out on your heads, and I will get $300,000 for every student I kill…" They were problem kids, who wouldn't be missed... Still who would have thought the teacher who threatened them on the first day would be the same one to end up saving them...

Rated M.

Intro

The new teacher walked in like he owned the place, without looking at anyone. He was a tall, skinny, almost a sickly looking guy and almost everyone in class was thinking the same thing. Fresh meat… E class had sent their last teacher running out crying, so they had expected her replacement to be the biggest most threatening guy the school could find. So when this twig showed up. No one was taking him seriously. They had all watched him enter, but they kept right on talking and laughing. No one was in their seats, some people were sitting on their desks and a few had actually called out to the teacher asking if his cancer treatments were going okay, since he looked so frail.

Without a word he picked up the chalk and began writing on the board.

殺せない

Of all the things to write on the board. Everyone kind of froze looking at the word. It was written in perfectly neat little strokes as though a child who wanted their writing to be as adorable as possible had written it.

"Korosenai," he read aloud. "Unkillable…"

He drew a line down after the character せ adding んせい below it.

"Korosensei," he continued reading. "Your unkillable teacher…"

He turned to face them for the first time smiling. He had on a suit and tie (typical of most teachers), but over top of it he wore a black trench coat and he smiled the sort of smile you would expect to see on small child who was excited to be heading somewhere fun. But his eyes were just the opposite, they appeared cold, and dark.

"I know your types, the worst of the worst at one of the most elite junior highs in Japan. The kids with no futures, no promise. And they shipped you all up here away from the main campus where you could learn your places, and be out of the way," he scanned the room taking in all their expressions.

No one was talking now.

"So here is the deal kids, they call me the reaper."

A few of the student's expressions changed upon hearing that, at least some of them knew the stories behind the reaper…

"I'm an assassin, the best one alive today. I was hired by, well, it's bad taste to reveal your employer. So let's just say there is a hit out on your heads, and I will get three hundred thousand dollars for every student I kill…"

A few of them looked scared now, but most of them still seemed confused as though convinced he were joking.

"So let's do some math kids, if there are twenty-five students in this class, and if I receive three hundred thousand a head. How much will I make if I, well, kill you all?"

No one answered his question, no one even bothered to do the math. They simply stared in awe.

His smile fell slightly, "You don't want to do the math huh? Well I can't say that I blame you. I wouldn't want to be crunching numbers in my final moments either. Oh well, let's get started. Below the floor boards, precisely under each one of your desks is a bomb," he reached in his pocket and pulled out a detonator. "It's not super high powered, but at that close of a range it'll be enough to end all of you. Goodbye."

He pressed the button, everyone gasped, a few people covered their heads, a couple students jumped up on their desks. A loud noise and purple smoke started rising up from beneath the floorboards. They all blinked as one by one they realized they weren't dead after all.

"Don't worry, wipe those panicked looks of your faces," he said grinning. "I am an elite assassin, it would do nothing for my reputation or my mood to off a bunch of junior high kids. I only kill people who are my equal. So, when you are, I'll take my reward and be on my way. Until then, I'm going to train you kids to be a worthy target for me."

Is he serious, Nagisa stared at him in awe.

"Let's also not be hasty, I will leave you alive until I deem you my equal unless you try to do something stupid like go to your parents or the police, I sure hate dealing with the police. So let's keep this between us and you kids will have a chance. Tell anyone and… you as well as your family will be goners, if you think I'm lying you're welcome to try me," he said cheerfully. "Now, first lesson. If those had been real bombs under your feet, what could you have done to save yourselves?" he asked simply. They continued to stare back at him, awestruck…

"What?" he asked curiously, not realizing that many of them were still in shock and couldn't pull their minds out of the situation this quickly to start participating in class. Or that maybe they didn't want to indulge the man who just threatened to kill them.

After a couple more seconds of stunned silence their was an instant uproar and all of them started to bombard him with questions.

"What kind of assassin let's their targets live?"

"Who the hell wants to kill us anyway?"

"Aren't assassins' supposed to be stealthy?"

"Like you're an assassin! You're to meek looking!"

"Oh geez, give me a break!"

Nagisa was the only student not reacting. Everyone else either didn't believe him, or were scared as hell.

"Please," Terasaka got to his feet looking angry. "Is that your ploy huh? You probably heard how we ran our last teacher out of here crying, and thought, gee. How can I scare these kids so the same thing won't happen to me? Pffft, give me a break, you're just a twig."

He aimed a punch straight as his face. The man dodged move around him faster than any of them to see, and the next think they knew Terasaka had fallen to his knees, the man was holding the side of his index finger against his throat. "You know, if I had had a blade, you would already be dead right now. Oh and coincidentally…"

He flicked his wrist an a small light weight dagger shot out into the palm of his hand. "I did. Which means you're only alive because of my good graces… If you wish to challenge me further, by all means. If not, then I would like to ask you to return to your seat."

He looked up at the classroom, "I would like all of you, to return to your seats."

That was how the greatest assassin in the world became their teacher, and his target? Was his students…

They couldn't wait to leave when it was time, everyone was appropriately worried by the time class had ended, which hadn't been long because he had arrived later in the school day. He gave all of them a final warning about not saying anything, or else, and then they were on their way home. They didn't even talk to each other on the walk back to the main road.

As weird as this situation was, Nagisa couldn't help but wonder, who would put a hit on ALL of E class? Who hated them that much to hire one of the most dangerous assassins in the world to come kill them?

He felt scared sure, but a small part of him wanted to meet whoever it was, so he could know why…

He opened the door to his apartment and called, "I'm home."

She had been seated on their living room sofa, across from her a man in a suit. It wasn't his Dad or anything. No his had had wracked up a gambling debt and abandoned them. His mother's job paid the bills and bought the groceries, but it was only just enough to do so. She was the breadwinner, and that meant, Nagisa paid the debt.

"There you are!" she said happily jumping to her feet. "Let me go get him cleaned up for you, it should only take a few minutes, make yourself comfortable in the meantime."

She grabbed his wrist and practically dragged him upstairs where she opened the hall closet which was dedicated to his… dresses.

"Put this one on, it's the cutest!" she exclaimed thrusting a pink dress into his arms. She rushed around him taking down his hair to brush it as he undid his shirt. "He's offered to pay five hundred dollars Nagisa so be good to him."

"…" he frowned. Last time he had checked, his father owed 265,000 dollars. If all future clients paid that much, he would only have to do this 530 more times. But in reality, not all of them did. He didn't sleep with the people his mother brought home, she sort of advertised him as a stress reliever to her clients where she worked and she let them come over and have fun with him for money. She would always tell him it wasn't illegal because they didn't go that far. But yeah, it was illegal, he had looked it up.

She brought him back down. "Here he is Mr. Amori, isn't he darling?"

"Yes, he is," the man grinned getting to his feet.

"Well, I'll let you two be," She said grabbing her purse from the back of a nearby chair. "Be good Nagisa."

With that she left the apartment, closing the door behind her, her son watching her leave through the strands of hair she had purposely combed to cover one eye.

It wasn't like he was the only one who had problems at home. He didn't know everyone's stories, but he knew some of them had it worse than him…

Karma fell back on the ground sitting up he spat blood on the floor. His Dad was in a bad mood again, but that was alright. He could handle a beating, as long as he kept his focus on him, instead of his Mother, then he would be happy…

"There you go," Isogai cut the fast food sandwich in half and gave one side to each of his siblings who he was watching while his mother was in the hospital... again.

"Yummy!" his sister said picking up her half she took a bit.

"Big brother where is yours?" asked the other.

"I'm not really hungry," He explained smiling, go ahead and eat up. He shrugged and began eating too. That hadn't exactly been true. Isogai couldn't afford anymore than what he had bought, and it was all his siblings were gonna eat that day, so he couldn't bare to take some of it from them for himself.

Kanzaki was dressed in her party clothes, and she flashed her fake idea at the bar to buy alcohol before taking a seat in front of one of the video games she loved playing. She liked this place because it was a bar, dance hall, and arcade all in one.

She stayed their for hours, and didn't intend to go home until well after 3 am. This was the best place to be to get away from the yelling…

"You brat, I ain't gonna ask you nicely again. Give me everything you got! All of it!" Terasaka demanded as he pointed his knife at a scrawny brat from another school. Muramatsu and Yoshida stood behind him looking threatening. He threw his bag at him and took off running. Upon searching through it they found a little money.

"Hey alright! Let's go get a pizza!" Terasaka threw the guy's wallet to his friends and they joked about how scared the kid was as they went to go get food.

"HINATA!" snapped the instructor after she had fallen off the balance beam for a fourth time. "Concentrate! Do you want to go to the Olympics or not?"

"Yes of course," Okano answered frowning.

"Well then you better straighten up!"

"We've been at this for three hours," she said climbing to her feet. "Can't we just… take a break?"

"Take a break!" her instructor snapped. "TAKE A BREAK! Do you think the girls from Russia are taking a break? Or those muscular things from America! Huh! No, if you are not eating, sleeping, or going to class, you are to be practicing! Now get back up there!"

"Yes ma'am," she sighed turning back to the equipment, she prepared to give it another go.

Nakamura had a lighter in one hand, and a container of gasoline in the other. The old convenience store down the street was her next target, teach the rat bastard who owned the shop not to pay the protection money from her gang, they were fairly small as of yet. But getting shops to pay protection money was a sure fire way to make her gang one of the biggest and scariest in Japan.

Under the guise of "studying at the library," her and her little street gang went out almost every night causing chaos and mayhem.

"Sorry Mr. Arakawa," she said after having one of her lackies dump the gas. "Maybe next time you'll pay without complaining…"

She lit it, and threw it. The fire erupted immediately and her and her group took off laughing.

"What the hell! I thought you said you were studying!"

The manga she was sketching was ripped out of her notebook by her Mother who looked enraged.

"Yuzuki! This is how you ended up in E class you worthless child! How do you expect to better yourself if you keep falling into pointless fantasies! Don't give me that look, this is your fault! Tomorrow you're going to come home straight after school and do your homework at the kitchen table where I can keep an eye on you. Ridiculous, and people at work always ask me why your falling so far behind!"

She covered her ears even as her mother continued to scream as she headed back down the hall to let her father know she had been slacking…

"Just do it," Okuda told herself as she gripped the glass she had made from various cleaning supplies around her home. "Just do it. It's not gonna hurt that bad, just go ahead…"

Her glasses were fogging up a little from her crying and breathing hard, and suddenly she burst out crying letting the drink spill into the sink.

Chiba met Hayami in back of her house and they crouched behind the bushes smoking and staring up at the sky. This was a nightly regiment, Chiba would steal smokes from his Dad and bring them to Hayami's house so they could smoke it together while her mother was passed out from drinking too much.

Sugaya used his spray cans on some of the houses creating obscene but beautiful works of graffiti. Okajima, who would sometimes tag along with him, just drew things that were obscene.

"You think that teacher is really gonna kill us?"

Sugaya shrugged, "Who cares," he pulled down the mask he was wearing so he wouldn't breathe in the fumes. "It's not like anyone would miss us."

"True, let's go to the next house huh?"

"Yeah!" Sugaya cheered throwing his paint can up in the air and catching it.

Kataoka winced when her Father hit her across the back with a wooden dowel.

"How the hell are your grades this low!" he snapped staring at the weekly progress report she was forced to get and bring to him. "I see you study all the time, and yet you fail all the time. Are pretending to study?"

"No," she answered looking back at him. "I'm studying very hard."

"My bosses daughter Kokona studies hard too you know, and she is one of the top in her class. So explain to me, how you can study just as much as her and not make the same grades!"

"I don't know how… I'll study harder…" she answered pitifully from her seated position on the floor.

Sugino got home to find a note from his parents. They had gone out, again. This was the fourth night in a row that he had come home to an empty house. His little brother had rushed downstairs asking about dinner.

With a smile Sugino headed to the kitchen to cook him something to eat. It was lonely without his parents around, but he had his little brother, so he supposed that was enough.

Hazama had gotten locked in her attic for mouthing off again, her parents didn't understand her goth nature and love of horror books and movies. She had been reading one instead of studying and her Mother had started screaming as she was prone to do whenever she got angry. Eventually she had had enough, slapped her and locked her in the attic.

It was okay though, she liked the attic. Dark and spooky places were really homier to her anyway.

Takabayashi had been rushed to the hospital. He was sure he was dying. He had caught the plague. Their was no doubt. But he had been sure last week too when he swore he had appendicitis, and the week before than when he would have bet every cent he had that he had a tumor.

The hospital no longer took him seriously, but his Mother would always come up and try to tell him how silly he was being. Despite how many times he would end up in the hospital, his Father never came to see him.

"You stole a bike!"

Justice stared at the floor not looking up at his parents who were both in their police uniforms.

"Do you know how embarrassing it is to be called down to the precinct when it's your kid who has been stealing stuff!"

"…"

"Answer me Justice!"

"I don't know..." he responded dully.

"Well it's incredibly embarrassing," his Father butt in. "That's it, it's too much. No more stealing, or next time we'll charge you for the crime as if you weren't our kid! And you will go to a juvenile detention center! Are we clear?" his mother snapped.

"Yes," he answered.

"We have to go to work, but you are not to leave this house!" his Father ordered before the two left for work. Justice reached in his pocket taking out a few candy bars and a handheld video game, which he opened and began to play. The bike wasn't the only thing he had swiped that day…

Kurahashi examined the diamond the old woman was trying to pawn. "I'm sorry, but this simply isn't real. Ten dollars is the best we can do."

"Ten dollars… oh… But I need it to buy medicine. That was my wedding ring that my late husband gave to me, I know it has to be worth much more than that…"

"Sorry… I can't give you more than it's worth, and it's worth ten…" she explained.

"Oh…" the woman looked saddened as she wondered what on earth she was going to do to afford her medicine that month.

"Alright, then it is…" she said disappointingly, and Kurahashi handed her ten dollars. When she left she went to the back grinning.

"Oh big brothers! Guess who just got a six thousand dollar ring for only ten bucks!"

The boys cheered and rushed over to her congratulating her. She smiled as they took the ring and admired it under the light, and her face fell slightly recalling the woman's desperate expression.

Maehara felt sick. He was sure he was gonna throw up. He was out with his two big sisters and they were cheering him on. "One more! One more! One more!"

His vision was already kind of blurry, he really didn't want to drink anymore.

"C'mon," his sister was almost as drunk as him, but could handle it better. "C'mon… you can drink one more! Be a man!"

Yea… he could drink one more… he thought to himself taking the drink in his hand.

"Oh, Kana has some had me downs," Sumire's mother exclaimed happily. She had been talking with her sister for over two hours before it got to this point. "Oh, well thanks, but I think not. Kana has some beautiful clothes, but I'm afraid my daughter simply won't fit in them. To be honest with you, she hasn't stopped eating since she got home…"

Sumire who was well within' earshot lowered the potato chip she was about to take a bite of, her heart sank slightly before she put it in her mouth and ate it anyway…

Mimura was sitting at the police station. He had been caught with his long range camera peeping on a neighbor. He wasn't really peeping, he was testing out the camera he had been playing with and the girl had just happened to see him and called the police.

His Dad however wasn't home when the police called for someone to pick him up. He was pretty sure his Dad was out with some slut… Like usual…

Toka Yada was sitting on the floor of her room. Even though it was happening on the floor below, it was so loud that had to cover her ears. Below, her father a Yakuza branch leader and his men were beating a man down for screwing up a job. She didn't want to have nightmares again tonight, so she did her very best to block the sound…

"Thank you very much Mr. Amori," his Mother said as she closed the door behind the man. She turned smiling holding the money he had given her.

Nagisa was standing not too far away, his hair was a mess, his makeup was smeared, their were marks on his neck, and he felt completely humiliated. But if they were a little closer to paying it off, then that was okay. It was almost midnight and he still had to shower and study. Even after going through all that he still had time to contemplate their new teacher. Koro-sensei was an assassin, who was going to kill them. But if he died, who would help his mother pay off their debt?

Their teacher was going to kill them, but only after making them worthy to kill. How exactly was he planning to do that?

If he had been told then what was going to happen, he wouldn't have believed it. I mean, who would think that a teacher who threatened to kill you on the first day of school, would end up being the same teacher who would end up saving all of their lives… and in more ways than one…

"Wow, I'm kind of shocked. No one actually told on me. I expected at least one of you to rat me out," Koro-sensei seemed to be in a good mood at the start of their next class.

"You told us not to!" Many of the students yelled back angrily.

"Well, yeah, but the bad guy always makes threats. That doesn't mean you have to listen to them. Either way, I'm glad you didn't tell. I really didn't want to have to hunt down any of your families. So, how about we start with—"

Maehara entered the class looking rather exhausted.

"Which one are you again?"

"Uh... Maehara Hiroto," he answered.

"I don't like it when people are late Maehara, it makes me feel like... they're up to something..."

"Um, sorry..." he took his seat looking leery.

"Well then, now that everyone is present let's get started..."

Maaaaan, ever since I finished this freakin' show I've been obsessed. So yeah… here is another story for you. This time Koro-sensei is trying to kill them and he's in his human form too. Not 100% sure where I'm gonna go with this, but I put up the intro to figure out if there is interest. If you wish to continue reading review and let me know so I'll update and make it a priority.
