I've been wondering about who would win in a fight. Korosensei or Slenderman.

I also like to imagine characters from shows becoming Slendy's proxies.

So, I decided to write this.

Enjoy, and don't forget to comment.

This takes place after the end of season 1, so shortly after everyone gets back from Okinawa.

"Screaming at children over their grades, especially to the point of the child's tears, is child abuse, pure and simple. It's not funny and it's not good parenting. It is a crushing, scarring, disastrous experience for the child. It isn't the least bit funny."

-Ben Stein

Time: 9:30 PM (The sun set around 2 hours ago)

Place: Public park

Nagisa sighed as he walked home. The blue-haired teen was very confused, life was never easy for him, but it was simple: don't argue with mother and try to get good grades.

After he was transferred to E-Class, those rules became: do not irritate mother and go to school.

After Korosensei arrived, everything changed. First, a new rule was to, or at least try to, kill his teacher. Second, he was happy.

…Happy…

And therein lies the problem. Nagisa had never felt happier than the times he was in class 3-E, and since his mother hated that class…it was like arguing with her.

Like he was breaking one of the rules he lived by for his entire life.

But, there was that part of him who relished in breaking free from those rules. A part that wanted nothing more than to be happy.

And that led to what Nagisa was thinking about, 'If we do manage to kill Korosensei, we save the world…and then what? A few of us might get the money, leaving the rest of us behind. I…I don't want to kill Korosensei, I just want-'

Nagisa's thoughts came to a screeching halt when he heard the rustling of leaves from behind him. Turning around, Nagisa squinted to see if anyone was there, but he couldn't see anything.

Nagisa called out, "Hello? Is somebody there?

No response.

Nagisa said, "Karma, if you're trying to pull a prank on me, it isn't funny."

A bad feeling was growing in the pit of Nagisa's stomach, so he took out his cellphone to use the light to see if he could see anybody.

Upon turning the flashlight on, Nagisa saw a tall, faceless man was standing right in front of him, just towering over the small boy.

Startled, Nagisa fell down, dropping his phone and scraping his arm against the hard asphalt path.

But he didn't notice that, the only thing he noticed, besides the tall man, was that static ringing in his ears and the undeniable sense of fear.

Forgetting his phone, Nagisa quickly got up and ran. After a minute, he looked back to see if he was being followed, and not even five feet back, he was just standing there.

The static in Nagisa's ears grew louder at the sight of him. The noise was blocking out every other sound, he couldn't hear his footsteps, the sound of nearby cars, or anything else except that static.

Nagisa kept running until he saw his apartment building, and he only slowed down because he was exhausted and because the static noise was receding until it was barely there.

After making it to his apartment, he stopped to catch his breathe, looked around, and upon seeing no trace of whatever it was that he just saw, he slowly opened the door, crept inside, and locked the door before quietly sneaking to his room to avoid waking his mother.

Once in the safety of his room, he quickly got ready to sleep, and tried to brush the whole thing off as some sort of hallucination, or Korosensei pulling a prank on him.

But, a piece of him knew that this was no hallucination, and he couldn't even begin to trick himself into thinking that Korosensei would do something so mean to one of his students.

He closed his eyes, and fell into an uneasy sleep.

ⓍⓍLinE BReAKⓍⓍ

An hour later, Nagisa was fast asleep.

His chest was rising and falling at a normal rate.

Without warning, the mysterious figure from the park appeared in Nagisa's bedroom, and turned his head, almost as if he was looking around, before looking down at Nagisa.

His long, bone-white slender fingers reached out, flickering before returning to normal, and put Nagisa's phone next to him before touching the boy's neck.

The phone flickered with a symbol of a circle with an 'x' going through it, and the mobile Ritsu app was modified. It was still there, but it wouldn't do anything except make the real Ritsu glitchy.

After that, the figure flickered out of existence, leaving no evidence that it was ever there, except for the circle with an x through it on Nagisa's neck…

ⓍⓍLinE BReAKⓍⓍ

The next day, Ritsu was taken out of class to fix the glitches in her system.

A few days later, during class 3-E's training session with Karasuma, Korosensei was going over the morning's assignment: write a free verse poem that ends with 'his tentacles are the best.'

Just about all of his students wrote nice poems about him so far.

Except for Karma, who ended his with, 'When it comes to cheating at board games, his tentacles are the best.'

Korosensei huffed to himself, "Hmph! I have never cheated at board games in my life."

Someone snorted, "Really? Then who flipped over the checker board last week when a student jumped one of your pieces?"

Korosensei greeted the speaker, "Oh, hello, Bitch-Sensei."

Irina growled, "Damn it, octopus, how many times have I told you-"

"Miss Irina, can you take a look at this particular poem?"

Frowning at Korosensei's serious tone, she complied, her eyes widening the more she read.

'Always watching,

Even though he has no eyes.

He is always there,

Just like the ringing in my ears.

I am never alone,

The static tells me how close he is,

But the static is always there,

He is always with me.

From the moment we met in the park,

To all the times he stands outside my window,

So long as he is there,

I do not feel fear.

I do not fear,

For he has shown me true fear.

He is fear.

And fear is now on my side.

I can no longer sleep,

He follows me in dreams.

But in life, he stands right behind me.

He never leaves.

His victims scream my lullabies.

Their suffering feeds him.

For when it comes to killing and torturing,

His tentacles are the best.'

And at the bottom of the page was a circle with an 'x' going through it.

Irina's eyes shot to the top of the page to see who wrote this poem, and her heart skipped a beat upon seeing the name.

Nagisa Shiota.

Looking at Korosensei, she asked, "What the hell does this mean?"

Korosensei shrugged, "I'm afraid I don't know. Some parts of this seem as if Nagisa's talking about a stalker, other parts make me think of Stockholm syndrome, some parts make me think of assassins, the end makes me think a bit about Itona, only Itona's never killed to my knowledge, and the rest…is a complete mystery to me. I was hoping you might have a clue. Something about this seems a bit familiar to me, but I just can't place it."

Irina shook her head, "Sorry, octopus, but I've got nothing."

Korosensei sighed, "I was afraid you would say that."

That night, Nagisa was doodling pictures of the mysterious figure he first encountered at the park and was trying to come up with a better name than 'mysterious figure,' when the door creaked open.

Nagisa said, "Mom, I'm in the middle of homework, do you mind if I try on dresses another time?"

There was no reply.

Nagisa turned around, and nearly fell out of his chair. For standing in the doorway, was Korosensei.

But this wasn't the Korosensei that Nagisa had come to respect and look up to; this Korosensei was rotting. His lower jaw was missing, his clothes were ripped, instead of a crescent moon on the tie, he had a red circle with a red 'x' on it, and parts of his flesh were missing.

The deformed Korosensei spoke, "This is your fault! You will do this to your favorite teacher! You will kill everything you love!"

Nagisa was backing away from Korosensei in horror, "No…no…no…please…I don't want to…"

A tentacle bent down to grab his chin and force him to look up, "Then leave."

The deformed Korosensei vanished; the only sign that he had been there was the open door.

Nagisa broke into tears. His mother heard this and went into her son's room, "Oh, Nagisa, I don't know why you're so upset, but I have something that will make everything better, all new dresses. How about you try them on now?"

Nagisa looked up at his mother with tear-filled eyes, "Mom-"

Hiromi gave her son a dangerous smile, "Try on the dresses, Nagisa."

ⓍⓍLinE BReAKⓍⓍ

Another day passed, Korosensei showed Nagisa's paper to Karasuma, who offered similar statements to what Irina said.

It was decided that unless Nagisa did something else, they would ignore this.

For a few days, everything was fine. Unfortunately for the teachers, it would seem today is the day that Nagisa's attitude would completely change.

When he showed up, he had heavy bags under his eyes, his hair was a mess, he looked like he had gone an unhealthy amount of time without the sun, was constantly biting his fingers and muttering to himself.

Because of this, no one was eager to start a conversation with him today, and if they did, no one was sure what to talk about.

This changed when Kayano shrieked in class, "Nagisa! Your hand is bleeding!"

This got everyone's attention; Korosensei quickly spun around and went to Nagisa's side to see if it was true.

Nagisa had bit through the flesh of his hand and didn't stop even after Kayano screamed, Korosensei had to pull Nagisa's hand away from his mouth.

Nagisa looked at his teacher with a confused expression, as if wondering what he did wrong.

Korosensei asked, "Nagisa, would you mind speaking to me in private for a few minutes? Class, got to Karasuma and tell him to start your training early today."

Everyone got up and left, many shooting Nagisa concerned glances first, not that he noticed.

Once everyone was gone, Korosensei spoke, "Nagisa, to be honest, I've been a bit concerned since I read your free verse poem the other day, but I decided not to take action unless I saw proof of something bad. Biting your fingers until you bleed definitely qualifies as 'bad.'"

Nagisa didn't respond.

Korosensei attempted to take another approach, "~Oh, is this because you can't think of any good assassination plans? How about I stand still for five seconds to make it easy-"

"NO!"

Korosensei took a step back at Nagisa's outburst, but the blue-haired boy wasn't finished, "NO! I…I don't want you to die. You're the first teacher to be nice to me, to ever treat me with a shred of dignity…and I…I don't want you to die…"

Korosensei was startled by his student's words, he may say that he doesn't want them to assassinate him anymore, but those were just jokes, "What about the world? Are you just going to let me blow it up?"

Nagisa stared at his teacher, but his eyes widened when the sound of static grew louder, "I don't care about the world very much, sir."

The static was getting louder. The tall man was getting closer.

Korosensei placed a tentacle on Nagisa's forehead, "Hmm, you seem a bit sick. Go home, get some and get some rest. You're excused from homework until you come back."

Nagisa nodded and left without another word, leaving a very worried teacher behind.

ⓍⓍLinE BReAKⓍⓍ

Nagisa's walls were decorated with drawings and sketches of the tall, slender man that has become a part of his daily life.

Nagisa stared at the images for hours, not moving besides the occasional twitch. The static sound from earlier had yet to diminish.

When Hiromi walked in, carrying brand new dresses for her son to try on, she walked towards her son's room, "Nagisa, can you come out here now?"

When no one exited the room, Hiromi became annoyed. She dropped the dresses, and went into Nagisa's room.

The sight of all the pictures on the walls infuriated her, "Nagisa, what is the meaning of this?"

Nagisa gave no sign that he even noticed his mother was in the room, which only sent the already angry woman into a frenzy.

Hiromi pulled Nagisa's hair, effectively getting his attention, "WHAT IS THE MEANING OF ALL THIS…THIS NONSENSE YOU'VE PLASTERED ALL OVER THE WALLS? DID I GIVE YOU PERMISSION TO DO SO? I DON'T THINK SO!"

Hiromi tore some of the drawings down, and the static fluctuated.

Nagisa grabbed his mother's arm, "Mom…please don't."

Hiromi smiled at Nagisa, causing the static to fluctuate even more than it already was, "Now, Nagisa, one day you'll see I'm doing this for your own good. Now, why don't you try on some wonderful new dresses I bought you, while I finish getting rid of these…ghoulish drawings?"

It was clear that the question was meant to be obeyed, so Nagisa left his room.

The static seemed to portray anger somehow, and the anger only grew the more Hiromi tore down all of Nagisa's drawings.

Nagisa kept walking past the dresses and into the kitchen. Once there, he pulled out the sharpest knife there and headed back towards the dresses.

Without a second thought, Nagisa cut the dresses to pieces. He couldn't stop the grin from taking residence on his face, and he certainly couldn't stop the laughter that burst from his throat.

The laughter caught Hiromi's attention, who stopped tearing down the drawings to see what her son was laughing at.

Upon seeing Nagisa tearing through the dresses, she felt angrier than she had felt in a long time, "NAGISA, WHAT ARE YOU DOING?"

Nagisa immediately stopped, and his grin died.

Hiromi took a step forward and opened her mouth to scream at Nagisa.

But the sight of her son adopting an even bigger grin before charging at her with the knife made whatever she was planning to say die in her throat.

All Nagisa could hear was the sound of his own heartbeat, his mother's screams, and the static, which seemed to fluctuate in a way that suggested laughter.

Nagisa stabbed Hiromi's arm, making her howl out in agony.

But that didn't matter to Nagisa, no…the static seemed to be communicating with him in a whole new way. And to Nagisa, that meant a lot more than Hiromi's pain.

Nagisa pulled the knife out of Hiromi's arm, and let her turn around to try to get away from her bloodthirsty son, before stabbing her Achilles tendon, making her fall down.

Nagisa grabbed his mother's hair and dragged her to the closest wall, before having her put her back against it for support.

Then in a quiet, dangerous voice, Nagisa whispered, "You wanted me to play dress up for you? Well, I'm making the rules now, and I say we play operation."

A psychotic chuckle was the only warning before Nagisa plunged the knife into his mother's stomach.

Hiromi screamed as tears ran down her face.

The static laughed.

ⓍⓍLinE BReAKⓍⓍ

By the time Nagisa was finished, Hiromi was missing both of her eyes, her kidneys, part of her stomach, her tongue, and all of her fingers and toes. But that wasn't all, her rib cage was showing, part of her face was cut off, and her left leg showed an attempt to skin it.

The sound of a police car startled Nagisa, so he decided to quickly end this, and stabbed his mother one last time. But unlike all the other times, when he was making sure that she would live, this time he aimed for a vital spot.

Her heart.

After pulling the knife out of Hiromi's heart, he ran to his backpack and pulled out one of his anti-sensei knives and placed it inside of Hiromi's ribcage before running outside.

Looking down at the roads below him, he saw a single police car, and two officers leaving the car.

Nagisa looked around and saw his neighbor's door open slightly, and a single eye was watching him, Nagisa grinned at the eye, and the door quickly shut with a locking sound.

Nagisa thought to himself, 'I guess they heard what was happening and called the police.'

Nagisa felt a bubble of fear as his adrenaline began to ebb, 'What should I do? What should I do?'

The static seemed to answer, 'Kill.'

Nagisa slowly walked downstairs, and approached the officers as they were about to walk up the stairs.

The officers stopped walking at the sight of the short teen covered in blood.

One of the officers asked, "What…*gulp* What happened here?"

Nagisa mumbled something unintelligible, and the officer bent down, "Huh? Sorry, kid, but I didn't catch that."

Nagisa quickly stabbed the man in the throat. His eyes bulged for a second before he fell down, dead.

Nagisa chuckled darkly, "I just told you the rules; I'm not going to repeat myself."

The other officer ran back to the car and called his superiors to tell them what had just happened.

Nagisa, guessing that he was calling for backup, quickly ran in the direction of the park.

The sound of more police cars surrounded the boy, and he ran faster.

Once inside the park, he saw all of the flashing lights surrounding it, and he knew, he was trapped.

But that didn't mean he would give up, so he quickly started to look around for anything.

But the sound of the static was distracting him, and he was somehow beginning to see it.

And then, he saw him.

The tall, slender man he first saw at this park.

…Slender man…

Slenderman

Nagisa chuckled, he finally had a name for this figure.

And then, he was gone.

The police searched, but none found any sign of Nagisa in the park.

ⓍⓍLinE BReAKⓍⓍ

The police decided to refrain from telling the public until they had either completed their investigation, gathered more evidence, or caught the boy.

The next day, while the police were continuing their investigation, Korosensei was taking attendance.

When he got to Nagisa's name, he felt as if he was being watched, and looked outside the window.

There, standing by the trees, was a short figure wearing a black hoodie that covered his hair, and on the hoodie, right over the figure's heart was a button of a yellow smiley face with small, black eyes. He also had black pants, and a blue mask that had two circles with 'x's going through them where the eyes should be and the mouth looked unhappy. The part that creeped Korosensei out the most, despite the expressions on the mask to look as if they had been drawn in blood, was the feeling of being watched.

Before the super being had a chance to do anything, another figure, a tall, slender man with no face, flickered into existence right behind the first.

And then, they were both gone…

ⓍⓍLinE BReAKⓍⓍ

Well, that's it. This turned out better in some ways and worse in others than what I was expecting, but I hope you like it.

Just to explain some things, in the beginning of the story, when Nagisa's thinking about not wanting to kill Korosensei, that was more of random thoughts than actually wanting to save him. I don't think Nagisa really wanted to keep his teacher alive until after we learn the truth about his past. But Slenderman manipulated his thoughts.

Made him think that him leaving would save Korosensei's life.

Please review, I have an idea for a two-shot, but I want to see how many people like this first. So really, please review, even if it's just to criticize me.
