Koro Sensei is busy reading a newspaper with sitting on lazy chair while drinking cup of juice. Tomohito is trying to kill Koro Sensei by using baseball while Nagisa and Tsurugi come along to see.

Koro Sensei: The moon is all they're talking about in America, too. I wish there were more interesting front-page news.

Tomohito is watching from behind the tree while holding a baseball with anti-sensei BBs embedded in it. Nagisa watch the way while Tsurugi just playing baseball game in his phone.

Tomohito: He makes a point of relaxing behind the school every day before class, with a drink and an English newspaper he got from Hawaii at Mach 20. *turn to Nagisa* Just as reported. Thanks., Nagisa.

Nagisa: *nod* Yup. Good luck, Sugino.

Tomohito: Got it. That ten billion yen is mine!

Tsurugi: *playing game* Using a baseball is a good idea, because it makes more silent noise.

Nagisa(In mind): We are killer. And our target is... our teacher.

Tomohito take a throwing position before he throw the ball directly toward Koro Sensei. But suddenly...

Koro Sensei: Good morning!

It makes Nagisa and Tomohito suprised by Tsurugi did expect this since he still playing game.

Koro Sensei: Remember, speak up when you greet someone.

Tomohito look at Koro Sensei and the chair twice. There's nothing but cloud of dust at the chair with the newspaper still float in the air.

Nagisa: G-Good morning, Koro Sensei.

Tsurugi: *still playing game* It doesn't work like always.

Koro Sensei: Embedding the anti-sensei BBs into a baseball? A fine idea! It won't make the kind noise an airgun would. However... I had all this time to kill to wait for the ball to arrive, and my cells would fall apart if I touched the BBs directly. So that's why I popped over to the equipment room to get a glove.

He raise up his right tentacle and show he have a baseball glove with the baseball with BBs in it, making Nagisa and Tomohito really suprised.

Tsurugi: *look up* I don't know we have equipment for baseball.

Green stripes appear at Koro Sensei's skin at the head.

Koro Sensei: I hope you can kill me-- before graduation, that is. *walk away* Now then, time for homeroom.

Tomohito: Yes, sir...

He look down as Nagisa and Tsurugi look at him.

Tomohita: Dammit. Guess my ball won't do the trick after all.

Nagisa: Sugino...

Tsurugi: Sugino, if it didn't work this time, then try next time.

Tomohito: *turn around* Tsurugi...

Tsurugi: In the end, you might be able to hit Koro Sensei with that ball. *back playing* Oh, crap. I have to do a homerun.

Nagisa/Tomohito(In mind): *sweatdrop* This guy is really a game freak...

(Time Skip)

Currently, Koro Sensei is teaching modern literature. The students are listening to his teaching while Sosuke is drawing Koro Sensei at his book.

Nagisa(In mind): Our teacher vaporized 70 percent of the moon. Next March, he says he'll destroy the earth. Whatever the reasons, this creature wanted to be our teacher. The Ministry of Defense gave us a mission: kill him by next March. There's a reward of ten billion yen!

Kaede: Hey, Nagisa-- Sugino's assassination attempt failed this morning, huh?

Nagisa: Uh-huh. He's been down to the dump since then. Tsurugi did try to cheer him up a bit.

Tomohita sigh as he look at his right hand.

Kaede: It's nothing to get bummed about. I mean, none of use succeeded yet.

Nagisa: Except that Tsurugi able to hit Koro Sensei few times.

Kaede: That's right, he's the first one that able to hurt Koro Sensei.

Nagisa(In mind): *look forward* An unkillable teacher. Hence the nickname Koro Sensei.

Suddenly Koro Sensei move in high speed and grab the book from Sosuke. Even Nagisa get confused with the sudden speed. Sosuke confuse where his book went to until Koro Sensei call him.

Koro Sensei: Sugaya-kun!

His eyes shine making Sosuke flinched. He thought he'll get scold but Koro Sensei impressed instead.

Koro Sensei: So close! But my feautures are a bit finer than that.

He shows the drawing. Koro Sensei himself draw with red pen and make the drawing of him look less chubby.

Hiroto: Finer how?!

Ryunosuke: Huh? Tsurugi, what are you doing?! We can't smoke!

Tsurugi: Huh?

He look up from the book and show that he have a cigratte but it didn't lit up.

Koro Sensei: Whoaaa! What are you doing, Tsurugi-kun?! Smoking is bad for your health!

Tsurugi: I see. Then...

He crunch the cigaratte as it gets even shorter into his mouth. As it completely in his mouth, he swallow and sigh. The whole class suprised with his sudden act.

Everyone(In mind): He ate the cigaratte?!

Koro Sensei: Eating the cigaratte is even worse!!

Tsurugi: What are you saying, Koro Sensei? That was candy cigaratte, not a real one.

Koro Sensei: Huh?

Then Tsurugi take out a cigaratte like box. Turns out it was candy cigaratte with fruit flavors.

Koro Sensei: *relief sigh* You sure scared your teacher...

Tsurugi: By the way, Sensei. *hold up one candy cigaratte* Do you want one?

Koro Sensei: Since it's a candy, okay, sure.

As his tentacle grab it, it melted making Koro Sensei back away as Tsurugi smirked.

Tsurugi: Sensei, you fall even for the most simple trap.

It reveals to be a fake candy cigaratte with anti-sensei substance. The other students really suprised he tricked Koro Sensei that easy as his tentacle grows back.

Everyone(In mind): He got Koro Sensei, again!

Koro Sensei: You've got me again. As expected from a professional assassin and gamer.

Tsurugi: Thanks for the compliment, Koro Sensei.

After the class, it's breaktime.

Koro Sensei: Now then, class, I have some business to take care of today, so if you'll excuse me...

Yuma: Business?

Koro Sensei: Yes. I'm catching a game in New York.

He move in Mach 20 and burst toward New York, leaving cloud of dust in the class.

Taisei: There he goes.

Ryoma: What's his deal?

Hinano: It'd be good if he brought back some souvenirs for us, at least.

Megu: Who wants souvenirs from their assassination target?

Hinano: Something to eat, maybe. That way it wouldn't stick around.

Megu: How oddly realistic of you.

Yuma: What could you bring back from New York?

Hiroto: Sake, maybe.

Yuma: We can't drink!

Hinano: Snacks would be the best after all.

Taiga: Or a blonde beauty... whoo!

Hiroto: Right?

Taiga: Blonde, blonde, blonde, blonde!

Tsurugi: Shut up, or I'll sent you two there myself.

Taiga/Hiroto: *turn to Tsurugi* You can sent us there?!

Tsurugi: Yeah, to the afterlife.

Then both of them change to down expression while the others giggles because it does kinda funny when Tsurugi threaten someone. They packing to leave until Karasuma and an agent arrived.

Yuma: Oh, Karasuma-san!

Karasuma: How's it going? Any clues on how to kill him?

Nagisa: Clues?

But all of them look down while Tsurugi wear his headphone, so he don't need to hear the conversation and continue to play game with his game console.

Kirara: Well, I mean, we are the E Class.

Yuma: It's impossible, Karasuma-san. The only one that ever hurt him is Tsurugi. He's personal weapon also could hurt him.

Koki: He's way too fast! You can't kill anything that flies at Mach 20.

Karasuma: Indeed, no army are capable of that feat.

Taiga: Told ya.

Karasuma: But only you have the oppurtunity. Whatever the reason, he insists on being your teacher. Left on his own devices, on next March, he'll blow Earth up. One look at that carved-up moon and you'll know: come on March, the entire human race will be beyond help. He's too dangerous to be left alive. This classroom is the only place he can be killed.

Nagisa(In mind): We E Class misfits had been given chance to be the heroes who save the planet. But I don't get it.

Tsurugi(In mind): Things even more messed up here.

Nagisa/Tsurugi(In mind): Why is Koro Sensei trying to destroy Earth? Why come to teach our class now?

(Time Skip)

It is lunch break. Everyone are having lunch in the class while Tomohito eat outside. Tsurugi eat his lunch while having conversation with Ryunosuke and Sosuke.

Ryunosuke: Killing Koro Sensei is too impossible.

Sosuke: Yeah.

Tsurugi: If you guys keep thinking like that, then it would be even more impossible. Think positive at some point.

Sosuke: Easy for you to say.

Ryunosuke: You kill people before. Of course you can hit Sensei.

Tsurugi: I'm a picky killer. I only kill does deserve to be killed, like the corrupted people, that's all.

Sosuke: But did you feel anything when you kill your targets?

It makes Tsurugi stops. He put his chopsticks down as he close his bento box and put it away in his bag as he sigh.

Tsurugi: Well... I did left not being right. After all, justice comes in all shape. I'm just... wanted to bring the right way to most place...

Sosuke: Well, at least your target is bad guys after all. There's no need to feel bad.

Ryunosuke: Sugaya's right.

Tsurugi: Believe me, after you just take the life of one person, it'll change you. *stand up* I'm going to go out and take some fresh air.

He went out of the classroom. Then Nagisa also went out to send the report to the staff room until he saw Tsurugi standing in front of the window.

Nagisa: What's wrong, Tsurugi?

Tsurugi: *point outside* Look.

Nagisa: *look outside* Koro Sensei... talking to Sugino? About what?

Tsurugi: Who knows. We can't hear from here.

Nagisa: Is... is he giving Sugino a talking-to about yesterday's attempt?

As they went out, Sugino was tied around with Koro Sensei's tentacles.

Nagisa/Tsurugi: Wow, he really up in his arms!

They went to them.

Nagisa: What are you doing, Koro Sensei?!

Tsurugi: What about the pledge you told not to hurt your students that I didn't hear you said because I'm not here at the first day you came?

Koro Sensei: Gehehehe... Sugino-kun... The unique pitching form I saw yesterday? You're copying the major-league pitcher Arita, aren't you? But you know, the tentacles don't lie.

He put Tomohito down as Nagisa and Tsurugi went beside him.

Koro Sensei: Your shoulder muscles are out of whack compared to Arita's.

Tomohito: What's that supposed to mean?

Koro Sensei: You won't be able to pitch his super fastballs with that body, no matter how much you try to immitate him.

It makes both Nagisa and Tomohito suprised. Before Tomohito speaks, Nagisa speak first.

Nagisa: How... *clench his fist* How can you be so sure?

Tomohito: Nagisa?

Nagisa: Because we're misfits? Because we're the E Class-- the End Class? So why bother? Is that it?!

Tsurugi: I kinda want to know as well.

Koro Sensei: Hm, well... how do I know do I know it's impossible?

He take out a newspaper and it shows Koro Sensei's tentacles tangled around Arita during the game yesterday right on the field.

Koro Sensei: Yesterday I check the man himself.

Nagisa/Tomohito/ Tsurugi: *anime suprised* Well, then, never mind!

Koro Sensei: I got his autograph, too!

He shows the autograph he got that written, "Knock it off, Tentacles! --Arita." Koro Sensei also crying happily.

Tsurugi: No way!

Nagisa: You asked him for an autograph like that?! How was he not furious?!

Koro Sensei: It was shock! Sheer shock!

Tomohito: *smile sadly* I get it... I don't have his talent.

Koro Sensei: On the other hand, your elbows and wrists are more flexible than Arita's. Train well and you can far surpass him. These fondling-for-compiration's-sake tentacles are never wrong. There's more than one kind of talent. Just like Tsurugi-kun, he's good in game make him very skillful in fighting. *walk away* Find an assassination that suits your talent.

Tomohito: My elbows and wrists... are better? My... my talent?

Tsurugi: Hey, Sugino. Want to play baseball?

Sugino: Tsurugi... Sure!

Then Nagisa went to follow Koro Sensei. He called him before Koro Sensei enter the staff room.

Nagisa: Koro Sensei!

Koro Sensei: Hm?

Nagisa: Did you went to New York just to give Sugino advice?

Koro Sensei: Of course. I'm his teacher.

Nagisa: Most teachers wouldn't do that far. But you will? The guys who's going to destroy the earth?

It makes Koro Sensei remember something in his past.

Koro Sensei: Nagisa-kun, I become your teacher to keep a promise I made. *checking Nagisa's report* I will indeed destroy the earth, but first, I'll be your teacher.

He show Nagisa how the report is.

Koro Sensei: Taking you kids seriously is more important than the end of the world.

Nagisa: *take back his book* Koro Sensei... *look in his book* Please don't write weird problems at the back.

Koro Sensei: Kyah!

Nagisa: I know you wanted to show off your grading speed, but...

Koro Sensei: It's like a bonus! I thought you'd be happy.

Nagisa: More like a penalty.

Koro Sensei: So, er, I hope you students take this assassination just as seriously. *eat the pen as green stripes appear* Even thought you'll never pull it off.

It makes Nagisa smile. As he walk through the hallway, he saw Tsurugi and Tomohito are playing baseball. Tomohito throw the ball hard but Tsurugi able to catch it even without glove. He turns around and saw Nagisa and asked him if wanted to join and play with them.

(Time Skip)

After class, Koro Sensei are making ice shaved from the ice he got from North Pole.

Hinata: There he is!

Hiroto: He said he'd be snacking on shaved North Pole ice today.

Koki: That octopus, hittin' the North Pole like it's corner shop!

Yuma: Now! Let's split the ten billion yen!

Everyone: Koro Sensei!

It makes him turn and look at the students. They run happily toward him.

Yuma: Can we have some shaved ice, too?

Koro Sensei: *crying happily* Oh! They're opened their hearts for me-- With such smiling face!

Then they take out the anti-sensei knife and jumped with evil smiling face.

Koro Sensei: How ferocious they must be!

They ready to stab him but Koro Sensei disappear with speed of Mach 20, leaving cloud of dust making them coughing until it's clear.

Yuma: Huh?

Koro Sensei: But you know... your smile are a liiitle forced. That wasn't enough to make me let my guard down.

Maki Maki! Tatsumaki! Hurricane Ninja!

???: Got you, Sensei!

Fuuma appear from the trees and attempt to stab Koro Sensei with his sword. But Koro Sensei disappear in cloud of dust.

Fuuma: Again?

Koro Sensei: Set aside the sword and dangerous anti-sensei knives, stop and smell the flowers, and learn with a good smile on your smile.

They look at their weapons and replaced with flowers.

Fuuma: Huh? *turn around* Hey, you guys. Don't you think these flowers look familiar?

Megu: Yes... *snapped* Hey, Koro Sensei! These are the flowers we've been growing!

Koro Sensei: Gyah! Is that so?!

It makes Toka and Hinata feel sad and cry.

Toka: That's low, Koro Sensei! We've been took such good care of them, and they'd finally bloom...

Koro Sensei: *panicked* I'm sorry! I'll get you some new bulbs! *disappear & reappear* Here you go!

It makes sweats appear at the back of Yuma and Hiroto's head. Koro Sensei are planting the new bulbs while being scold by Megu and Hinata.

Hinata: Don't go planting them in Mach speeds, now!

Koro Sensei: Understood!

Megu: Handle each one gentlely!

Koro Sensei: Right!

Hiroto: Hey... isn't he going to destroy the planet?

Yuma: Y-Yeah... And here he is planting tulips.

Ryoma, Taisei, Kirara and Takuya are watching them from behind the storage house.

Hiroto: That's right, where's Tsurugi?

Yuma: No idea. We pay too much attention on the flowers.

Fuuma: I'm done!

They, along with Koro Sensei, turn around and saw Fuuma is holding a bouquet of flowers. The flowers are the tulips that Koro Sensei take from the garden.

Fuuma: I don't know what to do with these flowers, so make it into this.

Yuma/Hiroto: When did you even make that?!

Fuuma: When the girls mad at Koro Sensei. I don't want to watse them so I make it like this.

Hiroto: You're just too cool, man...

Fuuma: I'm gamer and killer, this kind of thing is simple for me. *turn to Toka* Toka.

Toka: *turn to Fuuma* Yes?

Fuuma: *give her the bouquet* Here.

Toka: Eh? You're giving me?

Fuuma: Well, you upset about the flower place get ruin. That is why I make the flowers like this so you won't get upset. Also, Hinata is busy scolding Sensei so I can't give this to her because she might get mad at me.

Toka: *take the bouquet* Th-Thanks...

Fuuma: Now, back to where how to kill Koro Sensei! Smoke bomb!

He throw smoke bomb to the ground and disappear as the smoke clears. Toka look at bouquet before smiling and pink tint appear at her cheeks.

Hiroto: He's way too cool!!

While Koro Sensei still being scold, Nagisa is writing about Koro Sensei's weakness as Kaede went to take a look.

Kaede: Nagisa, what are you writing?

Nagisa: I thought I'd jot down Koro Sensei's weak point. I might get an assassination hint from 'em.

Kaede: *look at he note* Huh... And that supposed to be useful?

Tomohito: *snag the note* Whaddya mean? They could become useful. "Height: About 3 meters standing tall. Special moves: supersonic speed cruising." The hell is this?

Kaede: So... not useful, then.

Nagisa: Not right now. 

Fuuma: Sometimes, the useless things can be useful.

They look at the side and saw Fuuma hanging upside down while playing games.

Tomohito: You can even hang upside down?

Fuuma: I'm a ninja, of course I can.

Kaede: Tsurugi, you almost can do anything.

Nagisa(In mind): We are killers. Class 3-E at Kunugigaoka Jr. High School is the assassination classroom, and the other students are elite members of a pretigious prep school.

Karasuma went to see the principal and talk about the Class 3-E. Karasuma become the teacher for the class so he can help the students in assassinating Koro Sensei.

(Time Skip)

Karasuma is walking toward Class E campus after the Principal agree that he should make sure the students safety. As he arrived, he saw Kaede holding some bamboo sticks.

Kaede: Karasuma-san, hello!

Karasuma: Hello. Starting tomorrow, I'll be here to help out as a teacher.

Kaede: Oh, you will?

Karasuma: I look forward to it.

Kaede: So now you're Karasuma Sensei!

Karasuma: By the way... where is he?

Kaede: Well, Koro Sensei ruined the class's flowerbed, so to make up for it, he held an assassination tournament, but with a handicap.

They are trying to hit Koro Sensei by shooting anti-sensei BBs and tied the anti-sensei knives at the bamboo stick. They trying to hit him but he still too fast.

Koro Sensei: A little something extra by way of apology! Where else you could find another teacher who can move like this?

They can't even hit him. Fuuma stay quiet while he playing game while leaning at the wall. When doing assassination, he still remain in his Rider form.

Kaede: Any luck, Nagisa?

Nagisa: No. He's totally not taking us seriously.

Karasuma: You call this assassination?! Even Aizawa didn't join in.

Nagisa: *take out his note* But--hang on. Going by Koro Sensei's weak points...

Fuuma get close to Nagisa and Kaede as he put away his game console and take out a new weapon.

-Gashacon Shooter-

Pixels appear at his right hand and a gun similar like revolver appear.

Koro Sensei: I'm afraid it's no use, students of Class E! Even with this handicap, I'm still far faster! Killing me is a far-off dream--

Fuuma raise his gun and shoot the branch causing Koro Sensei fall on the ground and it turn into an awkward moment.

Fuuma: Go on.

Everyone: Now, kill him!

Koro Sensei: Rats! *dodging* Aahh! Too dangerous! Too dangerous! Too dangerous!

"Koro Sensei's weak point #1: When he shows off, things can get shaky."

Kaede: *sweatdrop* Those notes might come in handy.

Fuuma: I told ya.

Nagisa: Yeah. I'm gonna keep at it.

Koro Sensei: Hey... wait up! M-My tentacles tangled up in the ropes!

"Koro Sensei's weak point #2: Has an unusually short fuse."

Koro Sensei: Why, you little...!

He able to escape and went to the roof.

Taiga: Damn! He escaped!

Koro Sensei: You'll never make it up all the way here-- you lack the base capability. Ha ha! Dummies!

Masayoshi: And we were so close!

Fuuma: They can't, but I can!

Koro Sensei turn around and saw Fuuma hold rifles loaded with anti-sensei BBs.

Fuuma: You're mine!

He shoot rapidly the BBs as Koro Sensei dodge the BBs awkwardly while Fuuma laughing and able to hit three tentacles.

Koro Sensei: Hey, wait! I'm not ready! This is too suprising!

"Koro Sensei's weak point #3: Easily caught in some of Tsurugi's suprise attacks."

After few moment shooting, the rifles out of bullets.

Fuuma: Eh? Huh? I'm out already, huh?

Koro Sensei: *panting & wipe his chin* I'm doubling tonight's homework.

Everyone: How petty!

"Koro Sensei's weak point #4: No tolerance."

Then Koro Sensei get away again. But the students are cheering because this is the closest they get to kill Koro Sensei. They even talk about how they'll spend the ten billion yen if they get it.

Karasuma(In mind): Junior-high kids talking happily about assassination? This is one unsual space, all right.

Kaede: Nagisa, think we can kill him?

Nagisa: We will. Otherwise, we'd never able to face him again.

Karasuma(In mind): It's so strange... how the students with liveliest expression at this school... are here in Class E, with their target teaching them.

The others also call for Fuuma while he sitting on the roof as he moving his legs. They give him thumb ups because he helped them with the assassination.

Meanwhile...

At Ministry of Defense...

Two agents are talking to a boy. The female agent talk with the boy.

"Those are the circumstances. Given the crisis the earth is in, you must speak of them to no one. If this gets out, you'll be undergo a memory-wiping operation."

???: Eeeyikes!

"All members of the Class E have received the same explanation, they're already part of the mission. Once your suspension is over, you will return to the E Class. Therefore, you too will be given the assassination assignment."

???: So, uh... Does this rubber knife reallt work?

"Yes. It's harmless to human, but we guarantee it will work on him."

???: I don't care if he's not human... I always wanted to try... killing me a teacher.

The boy grin as he think something that he wanted to do.

To be continued...
