Hey so I´m gonna divide this into I don't know 2 or 3 parts. Because I can't retell the entirety of assassination classroom in just one chapter. This won't be overlong scenes, they will have their moments and them later the host will react to what happened. So, enjoy this.

Note if I get some of this wrong warm me. I don't know if I´m doing the right track or not, I followed more of the arcs of the manga. So, I hope that I got it right.

Haruhi was telling her friends all about Class 3-E and her dealing with Koro sensei and all the challenged that she need it to face in her life as being a member of that class.

''Everything happened two years ago. I was sent to 3-E because of my low grades at the time, at first, I was only ridiculed for being poor and now for having low grades, needless to say I hated that school.'' Said Haruhi all sincere.

The host with except of Kyoya looked at her with concern as she start her story.

Flash back

A young Haruhi Fujioka with a long hair enter inside the run-down shack of the infamous Class 3-E, so far everyone was nice to her. Maybe this class wouldn't be this bad as she imagined.

''Hi there girl aren't you Haruhi Fujioka? My name is Hinano Kurahashi'' Said the orange hair girl introducing herself.

''Nice to meet you.'' Said Haruhi liking this girl

''Nakamura. The pleasure is mine.'' Said the blonde

''Hi there names Meg Kataoka.'' Said Meg greeting Haruhi

''Nice to meet you all.'' Said Haruhi liking those girls

Soon a giant yellow octopus like creature appeared in their class. At first Haruhi was scared of him until a government agent explain the situation and it was said that he wasn't going to harm them.

''I will be your teacher for the year.'' Said the creature later named Koro.

''An octopus?'' Asked Haruhi confused

''Now try to kill me.'' Said Koro with a smirk.

So, everyone try out to kill this creature that their later named Koro but he was so fast that nothing could hit. Everyone tried at least once, except for one person.

''I am not killing you.'' Said Haruhi all serious. She was the only person in the whole class that hasn't try to shoot or stab Koro

''Huh.'' Said the entire class confused at this.

''Fujioka! This isn't a joke; you people are the only chance of getting this off the planet.'' Said Kurasama to the girl.

''I´m sorry agent but killing is wrong and I refuse to do that.'' Said Haruhi all serious.

''Are you for real? Even for a thing like him?" Asked Muramatsu confused

''I´m not killing anything. Its wrong.'' Said Haruhi still refusing to do that.

''if you don't kill him, he is gonna blew up the Earth and kill everyone. Is that what you want? Everybody dead?" Asked Terasaka all pissed at the girl.

Haruhi only looks uncomfortable at this. Yes, Koro said that he was gonna blow up the Earth at the end of the year and they were the planet only hope and that included her, but despite that she remember her mother words of not kill a living being, protect the innocent.

''It doesn't matter. He can kill me if he want but I´m not killing him.'' Said her shocking everyone.

Many of the students looked at her in shock for saying this. She would rather die than kill, she was serious about this?

''Haruhi.'' Said Nagasi in shock

''You don't know what….'' Said Kurasama rubbing his head in annoycne, he knew this might happen he just wish it didn't happen this ealy

''Allow me to interfere.'' Said Koro to Kurasma

Koro then went near Haruhi and put one of his tentacles near her. Any other student would try to stab him at this position but Haruhi allowed him to touch her

''Haruhi can you come to the teacher room please?'' Asked Koro

She accepted this and soon the two were sharing tea at the teacher room

''Now Haruhi please explain to me why don't you want to kill me? Is because of my charm?" Asked Koro all simple with his signature smile

''No is because even a ugly creature like you deserves to live.'' Said Haruhi

''You are so hurtful.'' Said Koro all sad

'Ok.'' Said Haruhi all confused

''But taking your lies asides you have a job to do here and as your teacher is my duty to help you achieve your goals. So Haruhi, explain to me what the reason is?'' Said Koro putting a whole psychiatrist look to understand this.

Haruhi then explain about her mother and how she told her to nerve kill. As a lawyer she need to protect the innocent and how her sudden death really impacted her and how she try harder to follow in her footsteps and achieve her dreams, but when her grades slipped she had no other choice then stay at 3-E

''I see. So, your mother really gave you those ideas and you follow them pretty high.'' Said Koro now seeing the situation

''Yes sensei. I can't even hold a gun; I feel wrong already just thinking of this.'' Said Haruhi.

Koro went close to Haruhi once more and decided to give a very emotional teacher student talk.

''I can see you wanting nothing more than just talk to her again. I mean you are a teenager and for what I saw so far. If only I…'' Said Koro leaving a suggestion

''Wait! Can you bring her back?'' Asked Haruhi with hopes

''Well I can't bring back the dead, but I can do many more things that can blow your mind off. Just wait here dear. '' Said Koro

Haruhi blink and in the next second Koro gave her a bunch briefs and suitcases all similar to the ones that Haruhi mother used (he pass to her house and looked at a picture of her to get the idea) and give to Haruhi. He pretty much gave her the essential kit to become a lawyer;

''Here you go my student. This is all yours if you follow your friends and try to kill me.'' Said Koro.

''But sensei, this is…'' Said Haruhi still not accepting this.

'I know and this was the deal that I made with the government. I can be your teacher and you all will try to kill me.'' Said Koro

''But why do this. Gather all this stuff and give to me. What do you want?'' Asked Haruhi

''I want to help you.'' Said Koro smiling

That took Haruhi by surprised, that creature was being so nice to her and giving her advices. She would never imagine that.

''Let's go back to class and we discuss this later.'' Said Koro

Haruhi only followed Koro and now her mind was surrounded by dozens of thoughts about what to do next. Continue denying killing, Kill Koro or what? She had a lot to think about it.

Later

It was lunch time know in 3-E and many people were surrounding Haruhi because of her lunch box.

'Wow Haruhi this smell amazing.'' Said Kaede looking at the lunch while eating her pudding.

''Yeah and looks so yummy.'' Said Hara drooling.

''You could make a career as a chef.'' Said Nakamura.

''Oh, is ok guys, most of these things are leftovers and the only thing I made was a omelet.'' Said Haruhi with a smile

''Very cheap stuff huh?" Said Murumatsu with a smirk

''I don't know still looks good.'' Said Sugaya.

''Can't your dad do something?'' Asked Nagasi talking to Haruhi

''No, he barley cooks. He is too busy with his job at the moment.'' Said Haruhi remembering that her dad works at a drag queen bar

''What does he do?'' Asked Sugino

''He is…a waiter.'' Said Haruhi. It was half true.

Soon Koro appeared and after finishing eating a snack that was the size of someone head he had his attention to Haruhi lunch.

''My my what do we have here?' Asked Koro drooling.

''Stop drooling octopus.'' Said Maehamara disgusted.

''Yeah didn't you eat snacks bigger than us a few minutes ago?'' Asked Isogai.

''I know but that was my morning snack now is time for my pre-lunch snack.'' Said Koro giving his reason.

''In what world is this normal?" Ask Meg

''You want some sensei?" Asked Haruhi offering her lunch to much of everyone shock.

''What! Haruhi you can't be serious.'' Said Fuwa in shock. Refusing to kill is something and now befriending this thing is another.

''Yeah let him starve. Maybe this way we might have a chance.'' Said Okano

''is ok guys. Koro sensei helped me early so I´m paying him back.'' Said Haruhi with a smile

''She is too pure for here.'' Said Terasuka now pissed.

''We might have her as our nurse or somewhat.'' Said Okajima imaging Haruhi in a sexy Nurse outfit

Haruhi was hiding behind her back a knife of anti Koro. Once he was close, she would try her chance.

''Here you go sensei.'' Said Haruhi giving the box to Koro

Then she did a deadly swing and a very fast one, you gotta be superhuman to see that. It left everyone in the class amazed. While it was a good try out, Koro of course escaped

''Wow!'' Said Nagasi surprised by this

''Missed.'' Said Haruhi annoyed.

'''What that…'' Said Kaede in shock to see Haruhi change from good girl to trying to kill someone.

''Miss Fujioka that was nice first try, you almost fulled me but you still need to have a better aim with the knife. Remember I´m a super powerful monster not a cheap beef at the supermarket.'' Said Koro applauding

''Hurray Haruhi is one of us.'' Said Mimura.

''He is now without a single friend in this class.'' Said Maehara

''Hey, I consider all of you my friends.'' Said Koro

Soon after the celebration was over Koro went over to Haruhi to congratulate her over her new ideals.

''Miss Fujioka is good to see you embrace the class mode. Now you are truly just like the others and with this attitude I believe you can pass High School. You mother would be proud.'' Said Koro.

''Thank you, sensei.'' Said Haruhi smiling at the monster

''So, can I have a bit now?'' Asked him

''No get your own food sensei.'' Said her denning him food.

''Oww.'' Said Koro all sad.

After that she joined the others in how to kill Koro and many times it never worked. Shoot him, stab him, explode him and the monster always escaped

She kept telling the Host about how she learned to use weapons, like guns and knives. That surprised them, Haruhi was always so good with the knife while cooking, they never expect that this was the reason. But she promised to them that she only aim to kill Koro and no one else.

Then she explain about the class infamous Red Demon Karma Akabane, that name raised the eyebrow of some of the Host especially Honey, Mori and Kyoya. The name Akabane was not unknow and if this guy was Haruhi classmate than he must be some real trouble to be around.

'At first he was ruthless at first sight, but he was such a nice guy.'' Said Haruhi with a smile.

''If you wanna work for me some day is just call me Fujioka.'' Said Karma with a smirk as he gives Haruhi the thumbs up.

That alone made Tamaki and Hikaru grind their teeth, that what they need another person to try to claim Haruhi heart. Kyoya brush them off this topic and return to questioning Haruhi, who later told them about the infamous assassin turn teacher Irina Jelávic or how she refer ´´Bitch Sensei´´

''Without her I would have failed in English.'' Said Haruhi remembering bitch sensei.

''Haruhi repeat this phrase.'' Said Irina to her student.

''I´m not doing that. This is ridiculous.'' Said Haruhi annoyed.

''Come on now. Do you wanna fail English, I know you all think as just a bimbo but I´m the only one here who is fluent in this language now say it!.'' Scream her.

''Fine.'' Said Haruhi with a defeat sigh

''I would love to spend the night with you.'' Said Haruhi sounding perfect in English.

Irina and the rest of the class was surprised by the way that Haruhi said that phrase. She didn't say like it was a recital, no it sounded like a real seduction.

''Oh, my Haruhi you sounded great. You know maybe you can become an international assassin and seduce so many mans.'' Said Irina patting Haruhi in the head.

''No way. I´m not gonna go and date whoever shows up.'' Said Haruhi annoyed and all red.

''But Haruhi, with your face any guy would melt for you.'' Said Irina with a seductive tone at her.

''Haruhi is a harem girl.'' Said Karma with a laugh as everyone in the class started laughing

''Yeah. Who knew that.'' Said Fuwa also laughing

''Guys!'' Scream her

Haruhi was embarrassed but she was also feeling a little bit of comfortable down with her friends. They were a little red, but they seen worst things than talking about Harem or other sexual things.

She continued to talk about her life in 3-E, but the Host wanted to know more about the school.

''What happened next.'' Asked Honey

''It was time for the midterm tests, and I hate to remember all the pressure that the others kids gave to us.'' Said Haruhi

She then explained on how the others class especially 1-A mocked her and her friends for being in the E class. They said so much hurtful things and horrible stuff, things that Ouran would never allow in their halls. Tamaki was already full of ´rage´´.

''How dare they do that to people who have difficulty in other majors.'' Said Tamaki irritated, if he ever saw one of those jerks.

''But that's how the world works. The stronger stumble the weak.'' Said Honey

''I will buy that school and make them stop doing that.'' Said Tamaki.

''Yeah. This way they will be force to study with the people who have difficult for their own reason, I mean we are not at the same level at Kyoya but we managed to get in Ouran, while I don't see the jerks from Kunugigaoka here.'' Said Hikaru.

''Do you people want to waste money for nothing?" Asked Kyoya

''Yeah!'' Said Tamaki, Hikaru and Kaoru ready to do some massive movement just to make Haruhi happy.

Those guys were idiots sometimes, but they were Haruhi idiots and she loved them so much. She would kill to protect them, and she mean it.

''They aren't like my classmates, but they are sometimes so naïve. I hope they never change.'' Thought her.

''So, I´m guessing the most intelligent students were in class A?" Asked Kyoya

''Yeah. They were the class of the son of the principal and his ´´friends´´ also know as the Big five.'' Said Haruhi remembering Asano, Araki, Sakakibara, Koyama and Seo

''Let me guess they were also the popular ones?" Asked Mori

''The deal is that grades were all that matter in that school, people usually went around them and worship them because of that.'' Said Haruhi

The host all nodded and know they saw on how cold and merciless Kunugigoka was.

''Also, there is one thing that I held back in my mind and never had the courage to say.'' Said Haruhi

''What is it?" Asked Kaoru

''Many of the students at that school were ugly as fuck.'' Said her remembering all the ugly people that her school had.

The Host were in shock to see Haruhi, ´´their´´ Haruhi using such dirty words like the F bomb in this situation.

''Mommy Haruhi is using dirty words again.'' Said Tamaki crying.

''Silence!'' Said Kyoya all cold

''Sorry.'' Said Tamaki composing himself

''Continue.'' Said Kyoya

''Right. So, where was I?" Asked Haruhi

Haruhi remember studying for the Midterm test, and how Koro would go around with his super speed talking to each student with a different headband.

''Ever single one of you have a major that you are bad at, today we are gonna change that.'' Said Koro all hyped.

''But sensei isn't this gonna make you tired. I know you are fast but even a monster like you need to relax.'' Asked Haruhi.

''Nonsense Haruhi. As we speak a me is outside having some relaxing time, I´m so jealous of him I mean me. So, let's get working!" Said Koro all excited.

''Why is my bandana?'' Asked Haruhi not seeing her Koro with a bandana.

''Your worst subject is science. I would suggest you study more and go to Okuda to have some help.'' Said Koro.

''Ok. I will do my best.'' Said Koro.

''Just be yourself and don't overact. You are smart, you can do it and believed it. Oh, sorry this was Terusaka.' Said Koro with a Naruto headband.

''I told you! Stop copying Naruto!' Scream the big bully.

She then went to explain how her, and classmates had to deal with the exams. Kuni was a school always going for the higher position in learning with some students saying that they prefer dying than stay near the loser class. She remember studying harder than she had ever did to pass those tests.

''It was tough but with hard work, some good friends, a bottle of cola and some tips I managed to prepare for the test.'' Said Haruhi making the host smile.

''Good. So, you went there and got the perfect score?'' Asked Tamaki

''Not exactly.'' Said Haruhi remeberign that day that while they did good, it wasn't enough to get attention.

''Even with all that study we managed to get near to the top.'' Said Haruhi in her class

''When I said that you all had potential I mean it.'' Said Koro showing that 3-E could reach the top no matter what.

''I guess we are gonna have to work harder.'' Said Karma

''Well we need to study more.'' Said Nagasi

''I´m loving this class. I love you all.'' Said Koro looking like a stupid open hearten guy.

''Koro sensei!'' Said the class ready to shoot him down, because he left his gard open

''Nonsense kids. Keep trying and believed it.'' Said Koro with a smile as he dodged the bullets

''Shut up! I study your tips happy!' Scream Terasaka

After that day, she went to look at the sunset while walking out of school and soon was approached by Koro.

''You were right Koro sensei

''I´m very happy to see you overcoming this Haruhi, I´m proud of you.'' Said Koro

''Want some rice balls?' Asked her

''thanks.'' Said Koro all drooling

Haruhi then pulled out a pistol from her desk and aim at Koro and he dodged

''Nice try. But keep trying, I´m sure you can handle.'' Said Koro smiling

''Sure.'' Said Haruhi also smiling at her teacher.

The host keep hearing about this in fascination. Outside of her family, Haruhi never displayed this level of admiration and respect to another person. She must really liked this Koro fellow.

''Sounds like that you respected him a lot" Asked Tamaki

''Yeah, Koro sensei might be a monster, but he had a good heart'' Said Haruhi

''Funny'' Said both Hikaru and Kaoru

Haruhi then only had good memories of Koro and her attempts to kill him, she could go on but Kyoya snap her to reality.

''I see and now how do you now that A.I?" Asked Kyoya

''Oh yeah Ritsu was created at first to kill Koro sensei but then he programed her to be part of our class. She is a great friend to be around'' Said Haruhi

''Cool Haru-chan. Ritsu-chan seems nice.'' Said Honey liking this

''I want to have a conversation with her in private sometime.'' Said Kyoya

''Not the topic at the moment.'' Said the other hosts.

'So, was all of your teacher at this class nice?'' Asked Hikaru, so far Haruhi was praising the teachers.

''Not exactly. There was one that I couldn't stand.'' Said her remeberign ´´him´´

''Who?'' Asked Mori.

''His name was Akira Takaoka and he was our replacement P.E teacher.'' Said her.

Haruhi told them about the sadistic drill instructor that at first seemed nice and talked like they were his family but then he showed his true colors. A sadistic asshole who only cared about his training and fame, he even hit and punched many of the kids in 3-E including Haruhi.

''He hit you.'' Said Tamaki in horror along with the host

''Yeah and its heart, it took me a week to get better.'' Said Haruhi putting a hand in her face

''That bastard. He better watch out!' Scream Tamki ready to hunt

''don't worry he is arrested plus Nagasi put him down.'' Said Haruhi.

''Nagasi?'' Asked Hikaru

''He is a friend of mine. Really sweet boy, he is the one with the best assassination skills, only rival to Karma. He made Takaoka drop to the floor and looked like a scary girl.' Said Haruhi smiling at that day.

''Man, he must be a beast of man.'' Said Tamaki imaging this Nagasi being a huge guy with muscles everywhere

'Well…'' Said Haruhi explaining on how Nagasi really was and that complete made him less cool

''So, he is girly?" Asked Mori with a sweat drop

''We did have the habit of dressing him in girl costumes. Mostly Nakamura and Karma, hell his nickname was ´´Gender´´'' Said Haruhi with a smile

''You got a nickname Haru-chan?" Asked Honey

''My nickname was ´´Crafter´´ do my way of getting cheap things into becoming weapons.'' Said her

''That so cute'' Said Tamaki

'Silence.'' Said Kyoya

''Sorry'' Said Tamaki

''Soon we received a visit of a new student who claimed to be Koro sensei brother.'' Said Haruhi

''BROTHER!' Thoguht the host of the image of that monster brother

''Who was he?" Asked Tamaki

''His name is Itoma and he wasn't really his brother.'' Said her explaining the whole deal with Itoma and the tentacles, Shiro and that whole complicated backstory

''Was he another experiment just like Koro sensei?" Asked Tamaki

''Yeah and his job was to kill him instead of us.'' Said Haruhi

''Did he succeed?" Asked Honey.

''No but he almost did, Koro sensei managed to win him out and he was defeated.'' Said her remembering the two-monster fight

''I guess he didn't prepare for this.'' Said Hikaru with a laugh

''After that he joined us and he became a good person, even if he was weird.'' Said Haruhi, she actually liked Itoma

''that's good to hear.'' Said Hikaru

''But even with that we faced a huge thing coming toward us.'' Said Haruhi

''What was it?" Asked Honey

''The end of the first semester and of our grades.'' Said Haruhi making the host anxious.

''So how did end up?" Asked Tamaki nervous

''Our class managed to get a lot of people in the top 50. Karma was very near the number one place and lost for a few points.'' Said her

''And you got what place?" Asked Tamaki

''I place number 21 on the exam.'' Said Haruhi a little happy

''Impressive.'' Said Hikaru

''So why the down face?" Asked Kaoru

''We didn't know what was about to come more into our future.'' Said her remembering what came next

Haruhi only looks at her friends with a doubt face. There was still a lot to tell and she knew she had so much time, her friends were out there fighting for survival and she was here stuck in this interrogation room
