Small Prologue~

You were getting ready to go to your now new school. Your (Y/N) (L/N), your (Y/A) years old, you have (H/C) hair, (E/C) eyes, and most of all... a terrible report card. Your parents are upset at you for having that low of grades, so they decided to transfer you to Classroom E, at the new school. When you were informed about this you didn't know what to say, you were upset at this, but at the same time you weren't. They told you everything about the school, except about you needing to assassinate your teacher.

~~~~~~~~~~~~~~~~~~~~~

With (Y/N)~

"I hope this school will be helpful for my grades." (Y/N) pauses for a second.

"I also hope *huff* I'm close to this school *puff*, because this *huff* is taking *puff* forever." (Y/N) says as she's slowly losing her breath.

(Y/N) then arrives and collaspe on the ground, she then looks up to see a small brown deadbeat school. 'Huh?' She thought to herself.

She looks at the building a little longer, 'Am I in the wrong place? Did mom drop me off at the wrong place?' (Y/N) thought to herself as she slowly gets up,

'I might as well go in,' She walks towards the building.

'As they say, you can't judge a book by its cover.' She then arrives at the door and opens it. She looked apund and didn't see anyone.

She then saw the sign that reads "3-E".

'This is the class I'm suppose to go in.' She takes a deep breath 'I should walk in with a big smile on my face and hope for the best.' She smiles sweetly and opens the door.

"Hello, I'm-" She cuts herself off from seeing the cold atmosphere all around everyone.

'Okay what the heck is up with everyone?!' She walks to a seat in the back and looks at her classmates as she's walking to her chair.

'What is going on?' She thought to herself while sitting down and waited for the teacher. 'I hope the teacher is at least a bit more cheerful.'

She then feels a loud thump like something crashed into earth. She looks around and sees a girl with green hair (Kayano) look out the window.

(Y/N) tried to look to but she didn't see anything. She then hears slimy slithering noises coming from outside the door.

The door then opens and kept her head down because she was afraid of what's in front of her and doesn't want to look up. Then a book was placed on the teacher's counter.

"Now, then. Let's begin homeroom. Class monitor, on your command." You heard a voice and you then looked up to see a yellow octopus.

'What...the...HECK!! What in the actual hell is that?!' You thought to yourself.

"S-Stand!" In your eyes you saw a girl with blue hair (Nagisa) said and stood up along with everyone else but they all had guns in their hands.

"Huh?!" You said in shock with your mouth wide open.

"Hey you, take your gun out, it's in your desk." A boy with two toned hair (Terasaka) said to you.

"What?" You look inside your desk, only to find a gun inside it, "What?!".

"Attention!" Everyone was silent for a minute. "Bow!" The blue haired boy said, and everyone started to fire their guns.

'Oh crap! These people are nuts!' You thought to yourself as you ducked under your desk just incase.

The yellow octopus starts dodging all the bullets at a very fast speed. "Good morning. I'll be taking attendants, so please, fire all you like. Isogai-kun?"

"Present." He answered still firing. "My apologizes. I'll need you to speak up, what with all this gunfire." The octopus answered back.

"Present!" Isogai answered back louder this time.

'How is this creature talking like this is a normal coversation for him?!?!' You thought still hiding under your desk.

"Okajima-kun?"

"Present!"

"Okuda-san?"

"Present!"

"Kataoka-san?"

"Present!"

"Kayano-san?"

"Present!"

"Kanzaki-san?"

"Present!"

~~~~~

When the shooting stopped, you looked up from your desk to see all the students worn out and out of breath. "All right."

The octopus closed the book, "Everyone is on time, I see. Excellent!" His face turns scarlet, "That makes me happy."

He looked at you, "And our new student has also came here on time. Welcome, I assume your (Y/N) I was informed about?"

"Y-Yes." You said still hiding in your desk.

"Hey, no need to be afraid new girl, we were only trying to kill him." A girl with blond hair (Nakamura) says to you.

'How is that suppose to make me feel beter?!' You thought as you sweat dropped.

"Besides he's too fast." She said in annoyance. "Yeah, not even the whole class at once can't bring him down." A boy with brown hair (Isogai) said to you.

'We... are killers.' Nagisa looks down at his gun. 'And our target...' Looks back up at the Octopus. 'is our teacher.' Nagisa thought to himself.

"Too bad. Not one of your bullets hit me today, either. Tactics that rely on sheer numbers neglect individual focus.

Be the line of sight, barrel position, or finger movement, each of you was far too easy to read." Octopus looks at (Y/N),

"Even (Y/N)-San looks easy enough to read." You whimper in fright, 'Please don't look at me.' You thought to yourself.

"You need to be more inventive! Otherwise, you'll never be able to kill me. I can speed up to Mach 20, you know?" He finishes.

"But, like see..." Maehara speaks up and points at the octopus. "There's no way you seriously dodged all of those!"

"I mean, these are just BB pellets." Sugino said while holding up the small pink ball. "You just coulda just taken them on the chin."

"Yeah! That's right!" Everyone saying in agreement. You slowly got up and sat in your chair.

The octopus sighed, "Very well. Gather up the BBs and hand them over." The octopus then took Okano's gun, "I told you: these may be harmless to you..."

The octopus brought up the gun, only to shoot one of his tentacles, causing it to move around and make a yellow liquid come out of it, it also caused everyone to gasp in shock.

'Oh my god...' You thought to yourself.

"But they're special anti-me BB pellets developed by the government. If one hits me, it'll slice through my cells like tofu." Everyone looked at the squirming tentacle on the floor.

"They'll regenerate a few seconds later, of course." The octopus says as his tentacle grew back,

"I'm more concerned about you putting a classmate's eyes out. No shooting in the classroom unless you're trying to kill me."

Everyone looks at him. He then had green stripes on his face, "And I do hope you can kill me-before graduation, that is."

'I don't like the look on his face.' You sweat dropped.

"Now then, let's put away the arms and ammunition and begin class." The octopus says and everyone sat down in their seats, putting away their weapons.

'At Class 3-E of Kunugigaoka Junior High School, the assassination classroom, the bell signals the start of another school day.' Nagisa thought to himself.

The octopus then starts to laugh. "But before we begin, we have a new student," Everyone looks back at you. "I want you all to be nice to her since it's her first day here." The octopus says.

'I hope I can make it through here.' You thought to yourself.'

~~~~~~~~~~~~~~~~~~~~

The octopus starts to write on the black bored, he then looks back at the class, "Now, here's the question:" He looks at a boy, "Isogai-kun!"

Isogai then replies, "Y-Yes, sir?"

The octopus then pulls out four different color tentacles, "Which of these four tentacles is not like the others?" The octopus asked.

"Um... the blue one?" Isogai answered. The octopus' face then turned scarlet, "Correct! The only relative pronoun i "who," in the blue sentence.

A reletive pronoun modifies the noun right before it, so the clause" The octopus explains.

Kayano then turns to whispeer to Nagisa "Hey, Nagisa." Nagisa turns to look at her.

She smiles and pointed at the moon in the sky, "The crescent moon's out in broad daylight." She says.

'How did we end up in this mess? As we began our third year of junior high, we were greeted by two extraordinary incidents.' Nagisa thought to himself as he looks at the moon.

Flashback~

In Space~

The moon was just sitting in space as usual, when there was an explosion, that caused the moon to have a crescent shape.

The first was the sudden explotion that left the moon permanently crescent-shaped.

In Japan~

"We interrup this program to bring you breaking news." The man on the screen said.

"We've just gotten word that about seventy percent of the moon has been vaportized into nothing. I repeat..." The lady on the screen said.

"Will we have only a crescent moon to look at for the rest of our lives?" A different women said on the screen.

In Class 3-E~

And the second was his arrival.

"How do you do?" The octopus greeted out. "I'm the one who tore that chunk out of your moon." He said out of the blue, making the students have a 'what?' expression on their face,

"I plan to do the same to the Earth next year. But, until then, I'll be your teacher. Nice to meet you."

The students sweat dropped at this, 'There has to be at least six things wrong with this picture!' They all thought to themselves.

The feeling was unanimous.

"I'm Karasuma, from the Ministry of Defence. First, please understand that what I'm about to say is classified information."

He sighed and then looked up, "Let me be blunt: I want you to kill this creature."

The students gasped. "Um... What's the deal? Is he an alien invader or something?" Mimura asked.

The octopus got offended, "How rude! I'll have you know I was born and raised on Earth!" He explained.

'He was?' Nagisa thought to himself.

"I'm afraid I can't discuss the details, but he's telling the truth. And as he said, he won't stop at the moon.

Next year... he will destroy the Earth as well. Only the world's leaders know about this.

If news of this guy got out there, we'd be looking at a global panic.

That's why we have to kill him in secret before that happens." Karasuma explained as he reaches into his suit.

"In other words: " Karasuma pulls out a green knife and tries to kill the octopus, "an assassination."

The octopus moves out of the way in a fast speed, "But here's the catch."

Karasuma tries to stab him, "His speed is unmatched!"

Karasuma tries again, "You try to kill him,"

He tries again, and the octopus goes behind Karasama, and starts grooming Karasuma's eyebrows," and he ends up grooming your eyebrows instead-immaculately!"

Karasuma just frustrated and the octopus' face turned pink.

The octopus then goes around with his speed making dust fly. "He's a superbeing with enough power to reduce the full moon to a crescent.

His speed tops out at Mach 20! In short, if he actually wants to get away from us, we wouldn't be able to do a thing to stop him." Karasuma says.

The octopus then puts away the materials for eyebrow grooming, in a small box. "But where's the fun in that?" The octopus says as he puts the lid on the small box,

"So I made your government an offer. They will refrain from attempts on my life." Karasuma gets upset,

"And in return, I'll teach Class 3-E at Kunigigaoka Junior High School." The octopus says.

'What? Why?' Nagisa thought to himself, while his eye was twitching. "We don't know what he's after." Karasuma says as he grows more angry,

"But we had no choice but to agree, on the condition that he doesn't harm any of you students. We have two reasons for this.

First and foremost, if he's coming to a classroom every day to teach, we can keep an eye on him.

And second, it gives some thirty people the opportunity to kill him from extremely close range."

End Of Flashback~

Nakamura then shoots a bullet at the octopus and he catches it with two pieces of chalk, "Nakamura-san." His face turns red, "Didn't I tell you not to let your assassinations interfere with your studies?" He says.

"Sorry." She replies.

"Stand at the back for the rest of this lesson and think about what you've done!" He says.

"How can could you make this creature our teacher?"

"And why are you making us assassinate him?"

These cries faded as one final conditionwas announced.

Flashback~

"Your success will be rewarded with ten billion yen." Karasuma said.

Everyone was surprised by this. "It's only fair. If you can assassinate him, you will literally save the Earth."

The octopus' face has green stripes, "Fortunately, he doesn't think much of you. See, those green stripes mean he's looking down on you!" Karasuma said.

'What is he, a chameleon?!' A student thought to themselves. "Of course I am! If the government can't kill me, how can you?" The octopus says.

"Even when they sent their very newest flyer jet after me, all it got was a good waxing right there in midair!" He says.

'What's with all the grooming?' A student thought to themselves. "So while this guy looks down on you, your job is to find an opening in his defenses and strike it.

We'll provide you with weapons and ammo that won't hurt humans but will work on him. You must keep this absolutely secret from your family and friends.

There's no time to lose. If the Earth is destroyed, we'll have no where left to run." Karasuma finished.

"And that's about it. Well then, I hope you'll make the most of your one remaining year!" The octopus says.

End Of Flashback~

We only have one year. If we can't assassinate him by then, the Earth will be history.

'I really hope someone will explain more about this creature to me.' (Y/N) thought to herself.

Lunch Time~

The bell rings, "Ah, lunchtime!" He goes towards the window, "I'll just pop over to China for some mapu tofu.

If anyone would like to try and assassinating me, just call me on my cell." He went out the window super fast.

'Him and his super speed.' You thought to yourself.

"How long will it take for him to get there?" You asked yourself.

"Let's see..." Nakamura started to think about it, you got up and walked to her, "If he's traveling at Mach 20... it'll take maybe ten minutes to get to Sichuan, the home of mapu tofu."

"Woah, really?!" You said with your jaw wide open.

"Guess no missile can shoot that down." "Heck, that octopus even grades tests while he breaks the sound barrier!" you heard students say. "Seriously?!"(Y/N) says.

"He even did a little drawing on mine." Isogai says to you. "That's unbelieveable!" You said amazed, "Isn't he a good teacher though?"

"He is (Y/N)! I aced my math test thanks to his after-school tutoring!" Kurahashi said to you. "He sounds amaing!" (Y/N) says.

"Yeah, but... we are in E Class." Mimura said. "Tryin' our best won't do much." Okajima said.

Nagisa looked at him. "Hey, Nagisa right?" You asked. Nagisa looked at you.

"Hi, I wanted to ask you, what's your opinion about all this." You asked.

Nagisa looked at you surprised, "Why ask me?"

"Well, you look like the one who'll at least explain a bit more about this to me. Since I'm new and all, heh" You said to him.

"Yeah... He might be an octopoid superbeing- not to mention our target-" Nagisa then looks down at his blade, "but... for whatever reason, he's teaching us just like any other teacher would.

Likewise, we're perfectly normal students outside of the whole killer thing," Nagisa looks at his classmates, "but E class is a little different from the rest." Nagisa said to you.

'Okay... he can really make something sound so questionable and dark at the same time.' You thought to yourself and sweat dropped. "Thanks for your opinion, Nagisa." You said smiling at him.

He smiles back, "No problem, (Y/N)." Nagisa replied. 'He has a cute smile.' You thought to yourself blushing a little.

"Hey, Nagisa." Terasaka called out. Both you and Nagisa turned to him, "Come with us. It's time to put our assassination plan into action." Terasaka said.

Nagisa nodded in response. "Assassination plan?" You said confused.

"I have to go, (Y/N). I'll talk to you later." Nagisa said to you, as he went outside with Terasaka, Yoshida, and Takuya. 'I wonder what their plan is?' You thought to yourself as they walked outside,

'And since I can't resist gossip, I have to follow them.' You thought to yourself as you followed them quietly.

Outside The Class~

"That octopus's face changes color according to his mood, right? Did you note down all the variations like I asked?" Terasaka asked Nagisa.

Nagisa took out his small notepad, "More or less. It's striped green when he's feeling confident as we all know.

When we give an incorrect answer, it's dark purple. A correct answer makes it go bright scarlet."

'Wow, those are some interesting notes, Nagisa must feel proud off himself.' You thought as you smiled.

"But what's really interesting is after lunch, when-" Nagisa was cut off by Terasaka. "I don't need to know all that."

Terasaka said as he walked down from his spot at the stairs, "I have a plan. And at the moment he least expects it, you are going to carry it out." Terasaka.

"M-Me? But..." Nagisa was unsure about his plan.

'Wow, I've never been this excited to know what's up. I need to know what's their plan...

...as soon as I find a bathroom, because I don't plan on pissing myself.' You thought as you walked away, 'Where's the bathroom?' You left to go to the bathroom.

"Don't be such a goody-goody. We're the E Class the regrets that failed to keep up at this famous prep school. They call us...

the End Class.

Every day, they send us to this isolated mountaintop campus and discriminate against us in every way like we're scum." Terasaka explained.

He then put an arm around Nagisa, "You think us losers are ever gonna get another chance to score a cool ten billion yen?"

Nagisa looked uncertain, "We're gonna climb our way out if this shithole..." He pulled out a bag from his pocket.

"any way we can." He dropped it into Nagisa's hand, and walked away, along with the two other guys, "Just don't screw up. Nagisa-kun." Terasaka said.

Nagisa looked down at the bag, '

"I heard Nagisa's headed for E Class."

"Ooh. Well, that's it for him."

"I better delete him from my adress book."

"Same. I don't want anybody to think I'm on his level!" '

Nagisa thought of the students who talked about him when they heard he was being transfered into E class.

You ran back only to see Nagisa alone, 'Oh... Dammit! I missed the juicy part!' You cried to yourself.

You were about to walk to him when you saw something coming down, you look to see the octopus. "I'm back." He says.

"H-Hello, sir... What's with the missile?" Nagisa replied. "A souvenir. The Self-Defence Force ambushed me over the Sea of Japan."

Nagisa sweatdropped, "I-It must be tough, having everyone after your life."

"Not at all. You know you're truly powerful when everyone has it in for you." The octopus stated, making Nagisa gasp,

"Now, I do believe it's time for fifth period." The octopus said as he walked inside. Nagisa looked down, "Yes, sir." Nagisa said.

You walked to him, "Hey Nagisa." You said grabbing his attention. "Huh? Oh, hey (Y/N). What are you doing here?" He asked.

"Well I just got here, and I saw you looking all upset, after talking to the octopus." You lied. "Oh, well, it's just, he doesn't understand." He said refering to the octopus.

"Oh? About what?" You asked. "If you're everyone's assassination target, that means they all acknowledge your power.

A creature like that wouldn't understand what it's like for no one to expect or fear anything from you, or even acknowledge your existence..." He answered looking down.

Nagisa heard his heartbeat as he thought of a another flashback.

Flashback~

"Thanks to you, my evaluation's in the gutter!" The guy said while scratching his head, "The only silver lining is I'll never have to see you again." He said looking away at Nagisa.

End Of Flashback~

Nagisa gripped on his bag, " I mightiest be able to kill him. After all, this teacher can't see me, either." Nagisa said. "Nagisa...?" You said feeling a bit worried about him.

~~~~~~~~~~~~~~~~~~~~~~~~
ASSASSINATION CLASSROOM
~~~~~~~~~~~~~~~~~~~~~~~~

"All right, then, compose a short poem to go along with our theme. The final line should be "Was tentacles all along." " The octopus said. "Huh?" Everyone is class said.

Kanzaki raised her hand, " "Was tentacles all along"?"

"Indeed! When you're finished, bring them to me. I'll be looking for proper grammar and whether you've aptly conveyed the tentacle's beauty." The octopus pointed out.

You raised your hand, "Sir, can you at least give us an example?" You asked. "Of course. An example:

"Not the storm of garden's snow

Or flowers moving on"

"But sprouting there instead

Was tentacles all along."

"We have to write it was tentacles? Really?" Isogai said in disbelief. "Once you're done, you're free to go home!" The octopus stated.

"What?" You said placing both hands on your cheeks. 'Aw man, and I wanted to go home and nap too.' You thought to yourself as you pouted.

"How are we gonna write about that?" Kurahashi asked.

"Now, now... Aren't any marvelously slithery phrases coming to mind? Slither slither slither slither!" The octopus said while moving his tentacles all around.

"Enough with the slithering!" Meahara shouted. The octopus turned light pink.

"I have a question!" Kayano said while putting her hand up. "Yes, Kayano-san?" The octopus replied.

"It feels weird to only ask this now, but... what's your name? How else are we supposed to refer to specifically?" She asked.

"My... name?" He responded. Sugino looks at Fuwa, "Now that you mention it..." He said. "He never did tell us." She responded.

"I agree." You said. "Hmm, I didn't know you had an opinion (Y/N)." Terasaka said with a smirk.

"Hey! What's that suppose to mean?!" You shouted at him. 'Her reaction's are funny.' Terasaka thought to himself.

The octopus rubs his head, "Hmm... I don't really have the kind of name you tell people. Go ahead and give me one." He said.

Meahara sweat dropped, "You sure about that?" He asked. "But right now, focus on your schoolwork." The octopus said. "Yes, sir." Kayano responded.

"Meanwhile, I'll just take a little break." The octopus said turning into a light pink color. Nagisa saw this and looked back down, only to get up with his hair covering his face.

"Finished already, Nagisa-kun?" The octopus asked. Terasaka smirked and laughed a little and Kayano gasped, noticing the knife Nagisa is hiding.

You looked up from napping, cleaning your drool that's coming from your mouth and saw Nagisa walking up to the teacher. 'Eh? What's his plan?' You thought to yourself.

'After lunch, right around the time we get sleepy, his face sometimes goes light pink. He was a little slow responding to Kayano's question, too.

That might be when he's at his most vulnerable.' Everyone is looking at Nagisa now, ' We prep-school failures are always thinking, "We gotta get back at 'em somehow."

"We'll show our parents, friends, and teachers that we can do it if we try."

We can do it if we try.' Nagisa then grabbed his knife and flung it towards the octopus, only for the octopus to stop Nagisa's hand with his speed.

"Didn't I tell you to be more inventive?" The octopus asked as he took the knife out of Nagisa's hand with a piece of paper.

'We have to prove ourselves...

Nagisa jumped towards the octopus, wrapping his arms around him, while smiling at him.

by any means necessary.'

The octopus then noticed the grenade around Nagisa's neck. Terasaka then pushed a button, making the grenade explode. You covered yourself from the pink balls and gasped at the sight you're seeing.

"Hell yeah!" Terasaka said. "We did it!" Takuya said. "Nagisa!" Kayano said covering her mouth.

"Ten billion yen! Cha-ching!"

"Serves you right!" The boys kept celebrating while going towards the corpse of the octopus.

"Terasaka!" Isogai said. "What have you done?!" Meahara asked. You walked over to the body. 'Please tell me he's alright.' You prayed.

"Bet he never expected a suicide bomber!" Terasaka said looking down at the black skin. "This was his plan...?" You quietly said with wide eyes, looking at Terasaka.

"Hey! What'd you give Nagisa?!" Kayano asked as she got stood up from her chair.

"Huh? A toy grenade." Terasaka responded to her. "But I beefed it up with gunpowder so it'd shoot three hundred anti-teacher bullets at crazy-high speed!" Terasaka explained.

Kayano gasped. "It's nothin' strong enough to kill human beings, all right?" Terasaka bend down,

"My ten billion yen'll cover his medical bills no prob-" Terasaka cut himself off from seeing Nagisa not injured at all.

"He's not hurt? Not even a single burn?" Terasaka questioned.

You saw Nagisa and ran to him, "Nagisa!" You kneeled down at saw clearly what was around him, and picked it up slightly, "Is this some kind of membrane?"

"It's attached to the octopus's corpse?" Terasaka asked.

"As it happens," Terasaka stood up, frightened from hearing the octopus's voice, knowing that he's still alive. "I shed my skin about once a month."

Nagisa stood up, breaking out of the skin.

You held onto him for being scared of the octopus and for Nagisa almost killing himself. "I protected Nagisa-kun there by covering him with my old skin."

Terasaka then looked up on the ceiling to see the octopus with glowing red eyes and a scary aura around him.

"It's my once-monthly ace-in-the-hole." The octopus said with a scary tone in his voice.

Nagisa looked at him while still holding onto you. "Terasaka, Yoshida, Muramatsu." The octopus called out.

'You don't have to look at the color of his face to know.' Everyone looked at him afraid as the octopus turns black and making his face looking more scary.

'Pitch Black! He is furious!' Nagisa thought to himself.

"You three... are responsible for this, aren't you?" Muramatsu let out a little shriek, "N-No!" Yoshida said. "It was all Nagisa's idea!" Terasaka said.

The octopus then left "He's gone!" Terasaka said. The octopus then came back. They looked down to see something scary, "The nameplates from our houses?!" Terasaka said.

"My agreement with your government prohibits me from harming you. But if you try another assassination like that one..."

The octopus then drops all the students' nameplates, "I might just harm someone else. Your family, your friends...

Maybe I'll kill everyone on the planet except you." The octopus opened his mouth, showing his sharp teeth.

Everyone gasped in complete fright.

'It only took five seconds for everyone to understand. Nowhere on this planet was safe.

Our only escape from this situation... was to kill him!' Nagisa thought to himself and looked back at Terasaka.

Terasaka spoke up, "What the hell's your deal, anyway? You're a real pain in the ass!

Showing up all "I'm gonna blow up the Earth" and "Assassinate me"! What's wrong with using an annoying method to kill an annoying guy?!"

The octopus turned scarlet. "Annoying? Hardly. Your idea itself was a very good one. Especially you, Nagisa-kun." The octopus rubbed Nagisa's head,

"The way you carried yourself so naturally on your approach gets full marks from me. You did an excellent job making it past my defenses. However!"

The octopus points at the three boys, "None of you looked out for Nagisa-kun-" The three looked down in shame,

"not even Nagisa-kun himself. Students like that aren't fit to assassinate anyone." The octopus turned dark purple.

He turned around to face the students, "We need an assassination worth smiling about- one to be proud of!

You're all capable assassins who have that power within you. Just a few words of advice from your teacher-cum-target."

Nagisa rubbed his head where the octopus rubbed, 'One moment we were being chewed out at Mach 20, and the next we were being praised with waving tentacles.

It wasn't your average education, but it made me pretty happy. All because this unusual teacher was actually willing to look us in the eye.' Nagisa tried to get up but he felt some weight on him.

He looked down to see (Y/N) passed out on his lap. He picked you up and he struggled a little, 'She's a bit heavy.' Nagisa sweat dropped.

The octopus then looked at the small burn on the table and thought of a memory.

Flashback~

"If you... If you're willing to give up your time, go teach those children." She gently touched the tentacles, "What splendid tentacles.

With hands like these, I'm sure you'll be a splendid teacher." She said with a sweet voice, smiling at him.

End Of Flashback~

The octopus put out the small burn on the table and looked up at Nagisa. You woke up, "Huh? What did I miss?" You asked. Nagisa put you down, and you looked at the octopus.

"Let me pose you a question, Nagisa-kun. I have not the slightest intention of being killed.

I will enjoy my time with you all until next March, and then I will blow up the Earth. If you don't like that idea, what do you plan to do about it?" He said.

Nagisa looked up, 'We've never assassinated anyone before, and there's plenty of other stuff we should be doing.' Nagisa tightened his fist,

'But, you know... I think this teacher might even accept us trying to kill him.'

"Before you destroy Earth... I'll kill you." Nagisa said smirking.

The octopus had green stripes on his face and laughed, "Then what are you waiting for?" He then turned to the class, "Once you've killed me, you're free to go home!"

Everyone complained, "Just like that, huh?" Nakamura asked. "You know we can't kill you!" Isogai said.

"That isn't fair!" You said. "Yeah, especially for (Y/N)." Okano said.

"Yeah- Hey!" You yelled out.

You and Nagisa walked to your seats, 'We are killers. And our target...' Nagisa looked back at the octopus, 'is our teacher.'

The octopus cleans the nameplates, "Wipe, wipe, wipe it clean!" The octopus said.

'If we tried to shoot him now... we'd just get polished like those nameplates.' Meahara thought.

'We're never getting out of here.' You thought to yourself sulking.

"An unkillable teacher..." Kayano said, Nagisa looked at her. " "Korosensai" for "unkillable," and "sensei" for "teacher"... Oh! What about "Korosensei"? "

"Korosensei?" Nagisa asked. "Ooh, sounds like a great name." You said smiling at her. Korosensei looked at them in surprise.

'So here we are with Korosensei... in our assassination classroom.'

Nagisa looks at Korosensei.

'The bell signals the start of another school day.'
