Horibe Itona had attack Korosensei three times.  Lots of stuff happened , but , in the end he finally joined E-Class. Then , a week later....the scene changes to the 3-E classroom.

"All right ,class. I'll see you tomorrow." Korosensei slid the window open. "I finally got paid so I'm heading out for some," he put on a bad Chinese accent, "Shanghai crab. Yi, er , san Go !"

As he leaving the class with a super speed aiming at the sky.

"No fair leaving us out !" Someone exclaimed.

Nagisa looked at Meahara as he sighed and leaned his head on his desk. "Now that it's the second term , our work's getting a lot harder."

"Korosensei's really trying to get our grades up," Nagisa said.

"That's nice and all , but I haven't picked up any girls in ages."

Nagisa chuckled awkwardly , glancing to the side. He seemed to notice something. Maehara and Nagisa strolled over to Itona's desk , where he was tinkering with a controller-like thing.

"You're stricking around , Itona-kun ?" Nagisa asked. "Hm ? What are you making ?"

"Just what it looks like : an RC tank," Itona replied.

"Why ?"

"He really ticked me off....so i'll use this to kill him."

Nagisa chuckled and Maehara leaned forward to examine the tech.

"Just like Terasaka's dumb face told me...."

"EH ?!" Terasaka glared at him.

The others boys son joined - except or Karma who already left - awing at the devices.

"I can fail a hundred times. So i'll go kill him , expecting the worst."

"Go kill him ? You mean......" Nagisa said uncertainty.

"B-But this thing..." Maehara tried to reason. "It's , like , super-high tech !"

A group of boys crowded around Itona's desk.

"Is this for real ?" Someone wondered.

Takebayashi peered into a camera lens. "This thing uses cell phone parts." 

"Wow Itona...You thought up theses tweaks your self ?" Isogai asked amazed.

" I learned basic electronic at my old man's shop. Anybody could do it." Itona replied. "Except Terasaka." 

Terasaka raised his fist at him warningly.

"Beside. I'm sure Karma could do a way better job." Itona said complimenting the absent red head. 

With that All the guys look at the empty seat.

"I agree." Isogai tone turn lighter. "That guy his not only good looking but he's also pretty protective." A flash back of Karma standing up for them from the other Main Campus students.  Nagisa smiled."Remember the incident one time ? Karma-kun was also good at gymnastics." A scene reveal Karma lifting a left foot on the air , doing a split and smash downwards to the enemy's head. " I can't believe he even have a talent in cooking !" Fuwa exclaimed. Karma was shown frying some food with E-Class students looked in awe , behind him. 

"Damn ! Those fried rice are the best !" Meahara gush.

Okajima drooled. "And don't forget those crispy fried chicken !"

"Well he doesn't save the day , especially last time with Itona."

Nagisa glance back at the younger boy. "Itona-kun's changed so much from when he had those Tentacles. " Nagisa thought , smiling in amusement. "Tongue's as sharp as ever, though. "

Marching music played as Itona set the tank on the floor. Everyone watched as the tank moved around.

"Woah ! " Okajima's face shone with excitement.

The tank turned and a small telescope-thing moved down.

The others were impressed as the small tank shot anti teacher BBs at the can knocking it down. 

"Amazing...." Hands on hips , Sugaya peered at it. "It's practically silent when it moves and when it shoots !"

"I used a lot of electronic controls to minimize gear noise," Itona explained.

Muramatsu whistled in appreciation.

"The camera feed is send to the controller, moving in tandem with the main gun's sight." The camera captured the knocked over cans.

"Wow , real spy stuff !" Maehara exclaimed.

"I'll let you guys in on something," Itona said. "There's one ideal place you should be aiming for our target's weak spot."

"Korosensei's weak spot ?! " Nagisa thought.

An imagine of Korosensei appeared , a target aiming him. 

"He has a heart. Right under his tie." It locked on to the crescent moon tie. "If we hit that , we can take him down in a single strike."

Korosensei laughed as he flew through the sky. "He has a heart. Right under his tie."He'll probably have spears the word by now—about my weak point , that is."

*Korosensei Weak Point #26 : His heart*

"Assassination is bound to get a lot more fun with Itona-kun in the mix." He blasted away.

The scene shifted to bits crowded around the controller.

"See anything ?" Okajima whispered.

"No - the camera didn't get that far. The filed of view is too narrow !" Maehara announced.

"Can't we put in a bigger camera ?" Muramatsu urged.

"It'll increase the weight , decrease it's mobility , and make target acquisition more difficult," Itona stated.

There were serval grunts of annoyance.

"In that case....." everyone looked up as Takebayashi spoke. "Why son't we use a fisheye lens on the camera ?"

"Takebayashi !" They yelled.

"Advisor : Kataoka Takebayashi" appeared.

An example of distorted images was shown. "If we have the CPU correct , any distortion in the received image.....even a small lens can get us a wide field of view."

"Got it. I'll find a small fisheye lens with a big viewing angle," 'Camera Crew : Taigai Okajima' decided. 

"Ritsu ?"

Ritsu woke up. "Yes ?"

"Can you build a distortion correction program ?"

"Sure ! I don't know what you need it for , but i'll take care of it !"

"You're a genius , Takebayashi." Okajima rested a hand on his shoulder in respect.

Takebayashi chuckled deeply.

They all looked pleased with themselves.

"We need a recording function."

"Yeah—it's a must effective analysis of our upgrades."

"And yet you were totally turned off by an underwear thief. " Nagisa buried his face in his palm.

"All in the mane of Assassination ! On ward !" Maehara ordered as the tank rolled toward the outside door. "Uh....Prototype 0 !"

Sunlight illuminated the tank as it jumped through the air.

It fell down the steps and landed on it!s side , on the grass.

"Uh......." everyone sweat dropped, staring at the controller.

"I'll go flip it over !" Kimura announced as he ran out the classroom door. He was appointed as 'High-Mobility Recovery Crew : Masayoshi Kimura'

 "Thanks , Kimura !" Maehara said with respect.

Takebayashi held his chin. "Shouldn't it's suspension be able to handle uneven surfaces ?"

"I'll come up with something," 'Drive System Planing Support : Taisei Yoshida.' offered. "I know a little about drive system and metalworking."

The tank was still lying down. "This light khaki chassis color is too obvious," someone pointed out.

"That's combat camouflage," another said.

"It's got to blend into the school or target might notice it," someone else reasoned.

"I'm on it. School camouflage. I'll paint it up," newly appointed 'Camouflage Managed : Sosuke Sugaya' stated.

The camera survey the empty school grounds. "RC stuff is hardly human sized. In the name of a better maneuvering , i'll draw up a map." A dramatic shadow fell over Maehara's face as his role as 'Road Map Cartographer : Hiroto Maehara' was announced above him.

The suspense action music suddenly broke off as Isogai and Nagisa sweat-dropped at the scene.

"They really loose themselves when smut is involved." Isogai said , exasperated.

"So sleazy."

Karma sighed quietly and  stare at them from afar , quietly observing them. "They are all perverts."

The screen faded. 'The Next Day : 6 AM'

All the boys from yesterday were once again gather around Itona's desk.

"Argh ! You idiot !" someone yelled.

The perverted group crowded around the controller , chatting excitedly.

"You gotta move carefully or it'll flip again !" Okajima said.

Terasaka placed a hand on Itona's Head. "Move ! It's my turn !"

Nagisa watched them from afar , smiling. "There was no need to worry whether the antisocial Itona-kun would fit in with our class."

Terasaka ruffled Itona's hair , both smiling widely.

Nagisa looked to the side as Isogai started speaking, "Itona , we're all working on this together. Why don't you give this thing a codename ?"

Itona looked down. "I'll think about it."

The tank stopped with a thud. "Ack ! It crashed ! Terasaka , you suck at this !"

"SAY WHAT ?!" Terasaka shoulder bumped a smiling Itona.

"Hey , Itona , isn't this lever a little loose ?" Someone asked.

"This is probably where I should have started all along."Itona looked back at the controller.

A shadow loomed over the stilled tank. A weasel watched it from above , squeaking.

"A MONSTER !" Terasaka and Maehara cried in panic.

The weasel sat on the rock , watching the tank struggle back and forth.

A flurry of voices began.

"Run !"

"No— Fire !"

The tank fired a small bullet at the weasel's chest , but it bounced off without making any damage.

"The main hun's nowhere near strong enough !"

"GOTTA TWEAK THAT, TOO !"

The weasel's face darkened as it sniggered. Suddenly a violent image of the weasel attacking the tank appeared.

"AHHHHHHHHHHH !!!" The weasel's eyes glowed red as it lunged forward , zeroing in on the tank. The boys solemnly inspected the broken tank.

"Dammit !" Maehara said. "To think we were done it by a weasel."

"Next time we'll need to assign a driver and a gunner." Okajima straightened up."You're on firing duty, Chiba."

"Uh......okay," 'Gunner : Ryunosuke Chiba' agreed hesitantly.

Itona uncapped a marker. "Mistake are all part of the development process." He wrote on the tank.

Nagisa watched curiously.

"Itona may have been a dud, but we'll spin it into something stronger. "Itona I" was written in the tank.

Terasaka smirked proudly as Itona continued.

"I can fail a hundred times , but I will kill him in the end." He glanced around. "Hope I can count on you."

They all grinned at him.

Maehara fist-pumped. "You bet."

"Bloodlust is what binds us together." Nagisa smile. "This is going to be fun."

"All right! By March we'll have this thing looking up all the girls skirt !" Okajima said when a hand same on his shoulder.

Nagisa smiled bemusedly. "So that's our goal now ? "

A hand grasped Okajima's shoulder with a slap and dark murderous was sudden glomming on the back ground. 

"What's this about our skirt ?" Kataoka asked as Okajima freaked out.

"Kataoka !" He flinched and panicked , arms waving wildly. "Nothing ! W-we were talking about s-side skirt on cars ! Y-yeah , that's all !" Okajima tried to save him self when other girls came in.

Okano walked over with Yada.

"Oh , we heard you."

"Boy suck , Beside Karma." They said glared daggers at the others.

"And just who came up with the idea ? I'm sure it wasn't you Itona " Kataoka asked angrily."I'm sure it wasn't you , Itona kun."

"Okajima." Itona deadpanned.

"Hey !" Okajima cried.

Ritsu woke up and turned to them."Good morning ! Oh, Okajima-san ! I have fish-eye lens correction program ready for you !" 

The girls glare.

"Wait ! It wasn't just me ! Right ?" He looked desperately at Maehara.

Maehara blankly looked away. "Beats me. Don't pull me into this , Okajima."

"MAEHARA YOU DIRTY RAT !"

"Just give up , guys." Isogai watched , unamused.

More girls glare menacingly.

"Either way , it's clear you were all in on this little scheme," Kataoka said.

Digging his grave further as all the girls started reprimanding at the boys.

Nagisa watched , smiling warily,

Karma strolled in at the scene. He watched the scene with question mark flying around his head , he turn to the bluenette that was beside him and rose a brow.

"Kind of a crime of passion." Nagisa explained with a smile , scratching his head and shrug. 

Karma nodded and walk away , ignoring them. 

Everyone was still boisterously arguing.

"No, it's , like, all adventurous !" someone protested.

Hara stood to the side , arms crossed. "You boys are impossible."

Itona , seemingly unfazed , walked past her to a certain Red Head. "Karma , I'm skipping school today. Show me a good spot." 

Getting the signal he went with the boy leading out of the classroom leaving them all behind.

"Hey , you Itona ! " Okajima tried to push through the crowd.

Who was form by ALL the girl yelling at them as Itona just stick his tongue out , not caring.

The scene flashed on the top of the hills , staring down. Two figures could be seen making their way at the end of the cliff.

" Why do you want me to come with you ?" 

Karma stare at the fluffy coulds  , bouncing above them. Color of Pink and yellow melt together in each other souls creating a gorgeous evening sky. The view was beautiful and gentle , it's suited for the peaceful soul that belong in the city.

He sat down with no sound. His leg swing on the air , freely.

Itona could been seen poking his head behind Karma , he shifted closer beside the boy and sat down beside him , staring at the empty spaces. None of them spoke as the silence continue to hang between them. When it was cut off by the younger male who let out a small sighed. 

"I just..... I just wanted to say Thank you." He spoke quietly.

Karma didn't utter a word but he gently turn to face him before Itona spoke up again.

"Thank you for what you did for me." Itona said , calmly before switching his sit position. "What I lost all the control of myself , when you found me simply lost control and started attacking everyone. When I heard your voice, it really calm me down." He stare down at the cliff while Karma eyes shifted away from his back and stare up at the nothingness."Just like the first time when I came here and stared attacking Korosensei , your voice was the same. " 

Itona continued.." It let me think rationally and slowly listen to Terasaka's word, If it wasn't for you ... I will attack or kill Terasaka without thinking. " he looked down at the cliff  " So ..... "  suddenly turn to Karma to met his gaze and next thing he knew , he was hugging him. " Thank you."

The Red Head didn't move a muscle as Itona continued to buried his face onto the others crook neck. "You bare all the pain...when you spoke my mind and I saw the pain , agony through your eyes that you have bare everyday in your life." Itona analyzed and praise. "You are really amazing Karma-kun." He look up and met a slight of warm and gentle swim around in that pair of beautiful mercury eyes , Itona blink in surprise before Karma hugged him back , softly. "You're welcome."

Unknown to the boy , the certain Red Head felt something was coming for them. Something....bad. He knew it's only the beginning.

Scene change to Shiro and an unknown businessman standing in an office.

"A grievance has come in from our Karasuma ," the businessman said , holding a phone.

"If we continue assassination attempt that involve the students....There's the danger of that monster feeling responsible and leaving the classroom. "Of you don't have confidence that you'll kill him for sure , be careful....." he says. "I agree , in that regard."

"Well , that's fine. I'll observe the situation for a while. I need to revise my plans anyway since I abandoned Itona."

He pause. "Besides."

"Besides.....?" Asked the businessman.

Shiro chuckled.

The scene shift to Class E , arguing still. Kataoka was shouting in Okajima's face.

"In that classroom, there's someone that's more of a monster than Itona."

The businessman raised his eyebrows questionably.

"He looks like he wouldn't harm a bug..." Nagisa stood in between Kataoka and Okajima , trying to break them up. "And yet , he possesses a fiendish bloodlust which even he himself doesn't realize he has..."

"But...." Then his eyes shifted to a certain Red head who stood behind the classroom , observing his classmate."...this boy. " Shiro squinted his eyes , trying to take a good closer look at the boy who was sitting beside Itona. "..I'm surprised , not even Korosensei figured him out yet."

The rat crawled into his mouth and Shiro bit down , blood splattering down his clothes as he crunched. "And of that doesn't work , I'll prepare the ultimate weapon."

The camera shifted into the classroom. "Eh ? So Itona is written with the characters for becoming thread ?" Kayano said , standing around Itona's desk with Kataoka and Kurahashi.

"One of those flashy names !" Kurahashi commented.

"Hey !" Kayano protested.

"It's a good name ! Sounds cool," Kataoka interrupted , keeping the peace.

"There are plenty of people with weird names in this class." Itona looked at Kimura , sitting upfront.

Kimura sighed , leaning on his hand.

The name "Masayoshi Kimura" written on paper dramatically appeared.

"What ? 'Justice' ?! I totally thought it was 'Masayoshi !' Kayano shriek.

A group of people were gathered around Kimura's desk now. "Everyone's generous enough to read it that way, yeah. And I asked Korosensei to call me that , too."

"Sure made us nervous, hearing your name at the entrance ceremony !" Sugaya said.

"Yeah , I guess." Okajima glanced back at him.

Kimura lowered his head. "I hate the thought of another public execution come graduation."

 Nagisa smiled sympathetically. "Kimura-kun's parents are police officers. " The Katana for 'Justice' appears next to him. "They were so high on Justice that they named their child that."

Soon everyone started complaining about their names.

Karma sighed disappointedly stretch his arm."You guys sure don't know how to appreciate what you're given."

Everyone blinked , confused. Kimura looked down in contemplation. "Hm...."

"I'm not satisfied with how I was named , either," Korosensei suddenly said.

"Huh ? I thought you liked 'Korosensei.' Kayano named you that." Sugino questioned.

"I do like it. That's why i'm not satisfied. There are still two people who won't call me by that name." He stare at Bitch-sensei and Karasuma, who jolted.

He started sulking. "Karasuma-sensei just says 'hey'" Korosensei impersonated him, "or 'you there' We're not some middle+aged married couple !"

Bitch-sensei squirmed. "But it's embarrassing for a full grown adult to be like ," she put on a school girl voice. "Korosensei !"

Karasuma's face darkened and he turned to the side , sighing shorty.

"Then why don't we call each other by code names instead ?" Yada chirped.

"Codenames ?" Isogai asked.

The scene changed: a foot hopped on a creek stepping stone. The forest was seemingly deserted.

"Baseball Geek, Baseball Geek!" Sugaya called into his phone. "Any movements from the target?"

Sosuke Sugaya Codename : Lanky Artist 

Sugino sat behind a bush,  "Nothing yet , Lanky Artist ! De Densest is hiding in wait near a lone pine." 

Tomohito Sugino Codename : BaseBall Geek

Isogai crept down the hill with Maehara.

"Team President Poverty will come from behind , chase him into the swamp. And the Bipolar sniper will fire on him." He stated as President Poverty and Womanizing Scumbag moved in.

Isogai Yuma Codename : President Poverty

"Will come from behind , chase him into the swap , and then Bipolar Sniper will fire at him."

Hayami peeked out behind a bush.

Rinka Hamyami Codename : Bipolar Sniper

Maehara cocked his gun.

But they were easily passed by Karasuma-sensei.

Karasuma sprinted past them. "Shape up, you two! How can you let your target leave the scene? Especially you, Womanizing Scumbag! Always hold your gun at firing height!"

Hiroto Maehara CodeName : Womanizing Scumbag 

Maehara gritted his teeth. "Dammit! Like I'll let you escape!"

Mimura, Kanzaki and Kurahashi crouched together, guns out. 

"Director Mushroom! Mistress Kanzaki! Fluffy Stag Beetle! He's headed your way!" Maehara shouted.

"Got it!" Kurahashi jumped off a ledge. Karasuma swerved and sped off, jumping about. "Ah! He went another way!"

Koki Mimura : Director Mushroom

Yukiko Kanzaki : Mistress Kanzaki 

Hinano Kurahashi : Fluffy Stag Beetle 

"Home Base!" Terasaka called.

Yoshida braced himself behind a bush. 

 "Loofah!" Muramatsu hid near a rock.

Ritsu : Home Base

Takuya Muramatsu : Loofah 

Itona Horibe : Picture Book Graduate 

Itona watched behind a tree.

"On it!" Yoshida ran off.

"Get him looking at the ground, and..." A scope aimed at a target sign. Terasaka fired, perched on a tree branch.

Kurasuma smiled in approval as the target on his back was hit. 

"Nicely done, Pseudo-Takaoka." Terasaka stuck his tongue out wildly.

Ryoma Terasaka : Pseudo Takaoka 

"But it's not enough!" Karasuma kept running. "Scoring one hit on me doesn't mean you can ever take him down!"

 His eyes narrowed in on Okuda and Kayano hiding in bushes up ahead. "Poison Spectacles! Forever Flat! If I can see where you're firing from, I can dodge your shots!"

"I'M NOT EVEN THAT FLAT!!" Kayano growled , shooting with anger. 

"He saw us!" Kayano said. "Take over, Dignified Didact!"

Manami Okuda : Poison Spec 

Kayano Kaede : Forever Flat 

Kataoka leaped out of some shrubs. "Okay! C'mon, English Lass and Gender!"

"Roger!" Nakamura and Nagisa ran behind her.

Rio Nakamura : English Lass

Nagisa Shiota : Gender 

Karasuma startled and quickly dodged several paintballs. He hid behind a large rock. "Nice shooting this time, without giving away their location. Must be Dignified Didact's leadership. Keep your distance from behind, then wait for your chance..."

Karasuma Sensei CodeName : Da Densest 

Fuwa and Okajima ran together.

 "Terminal Perv And This Manga is Amazing! aren't bad, either."

Okajima Taiga CodeName : Terminal Perv

Fuwa Yuzuki : This Manga is Amazing 

Isogai glanced to his left. "Red Mystery has blocked the escape route!"

Karma eyes lit up lightly, aiming with his shotgun.

Karma Akabane : Red Mystery

Isogai looked up. "We're counting on you, Dating Sim Emo Character!"

Chiba aimed and fired at Karasuma, who blocked it with his shield.

Ryunosuke Chiba CodeName : Dating Sim Emo Protagonist 

"Dating Sim Emo Character! Assume your target is always on guard!" he shouted.

"I know." Chiba thought, smiling a bit and pointing up, then down. "But I'm not the one who'll take you down." In slow-motion, Kimura jumped down behind Karasuma. 

"Justice! " Kimura grunted and fired his two guns, as Karasuma turned around.

Masayoshi Kimura Codename : Justice 

The shots rang out through the forest.

 Back in the classroom, Koro-sensei laughed. "So how did it feel, spending the day under codenames?" 

 "Kind of...painful," The students groaned, embarrassed heads down.

"'Scrunches and Boobs'?" Yada sobbed.

 Okano laid her head down. "Being called 'Amazing Ape' over and over..."

Meahara growled , crossing his arm."I mean seriously Karma had the only cool code name." He lean his back against the chair. "Red Mystery ? Why couldn't I get that instead of Womanizing Scumbag ?" he gritted his teeth like a caveman.

"Just to reassure you, Kimura-kun," Koro-sensei held up a name change form, "it should be relatively easy to put in for a name change." 

 Kimura smiled. "Oh, right!" 

 "Still, Kimura-kun... If you kill me, I bet this is how the world will see your name:" A newspaper article with 'His name is JUSTICE!!' as the headline came up. He put on a reporter voice, "'Justice' indeed! A perfect name for the hero who saved Earth!" 

 Kimura blushed slightly and pondered.

"So! Today's the day we used codenames. Now to tell you mine!" Korosensei wrote on the board. "Please call me this from now on: 'Prince of the Fateful Eternal Wind'." Everything was sparkly.

 The class was silent.

The previous warm mood was broken.

"SERIOUSLY!!?" 

 "What the hell is that pretentious shit!?" Terasaka swore.

"Why do you get to pick such a fancy-pants name?!" Maehara screamed as everyone attacked.

"And what's with that smug look?!" someone growled. 

 "Aw, c'mon, why not? Just for one day!" Koro-sensei begged. "Koro-sensei spent the rest of the day as 'The Octopus of the Idiotic Perverted Chicken." Nagisa narrated. 

 "The Octopus of the Perverted Chicken!" the students yelled, firing.

"Huh? Octopus?!" Koro-sensei cried. 

"Sure was funny today, using codenames in class," Nagisa said, near Itona's desk.

"Sure was," Sugino agreed, they both turned to Itona. "Right, Picture-Book Graduate?" 

 "Can it, Baseball Geek," Itona shot back. 

 Sugino laughed. "Ouch!" 

Nagisa smiled, amused. "What does it even mean?" Itona muttered.

"Seriously ," Sugino crosses his arm , frowning.  " Karma-kun , you're the only one who has a cool Code name. I mean Red Mystery ? How awesome it that ?"

Karma stood up , grabbing his bad and toss over his shoulder. He shrugged.

 "Yeah, and whose big idea was it to put me down as 'Forever Flat' huh?" Kayano shrieked.

Muramatsu flinched and whistled, walking out.

"So it was you," 'Codename: The Art of Darkness' Hazama mumbled.

"See you tomorrow." Itona walked over to Terasaka's gang. 

 "Hn?" Nagisa observed.

"Hey, I'll put up with that nasty ramen today again. C'mon." Muramatsu jokes as they left.

And so the day went on , each students doing their best. But , they were the End-Class. 

Their fun times couldn't last forever.
