Karasuma wanted to know some more information on the mysterious boy. He checked his background information , but nothing was found.

A Flash back of him hidden behind the wall , watching a woman in black stood infront of the boy.

"Interesting." Says Karma Akabane in question. He was holding something in his hands. "This progress is worse than I heard."

Karasuma and the agent realize what he was holding were the file of Korosensei. Some how had gotten them from in front of Karasuma and read a considerable portion , and Karasuma had never seen Karma move an inch.

"Sure." the boy spoke up , breaking the tension. Karasuma and the agent exchange uneasy looks. He studied their nervous glance at the boy. "But.." the boy trailed off. The room felt into a uncomfortable silent that send weird chill down Karmasuma's Spine.

He looked at the boy , carefully. A sweat break from his forehead."W-what the-"

The boy place the paper down on to the table. "If you fucked up..." He reach out the knife and examined it. "You know what will happen ," the boy titled his head to the side and break the metal knife with his hand. "right?" The agents jumped by the sound and tried to remain their composure.

Karasuma looked down at his computer screen and gritted his teeth , nervously. "That boy..."

The screen faded back to inside the 3-E classroom. The students were silent , trying to sit a pop quiz , but there was a loud squishing noise disturbing the silence. Korosensei was trying to punch the wall with his tentacles.

"Um...What's Korosensei been doing all this time ?"

" I don't know , I think he is trying to punch the wall ?" Mimura whispered.

"You're right ," Meahara murmured. "Karma smack-talking must have made him mad." He leaned forward to scrutinize the soft tentacles hitting the wall."But aren't his tentacles too soft to even damage the walls?"

*Koro-sensei's weak point #4 : his punches are soft.*

This noises already getting people some nerve. Korosensei is now acting like a hurt puppy.

Like- I'm hurt , can someone come kiss my boo-boo ?

Absolutely fucking ridiculous.

Then Hinato snapped."Oh ! Enough with the SQUISH ! SQUISH ! We're trying to have a test here !"

Korosensei paled. "P-Pardon me !"

The class was on edge, no one talked to Karma and tried their best not to look at him. Which he didn't really mind as it gave him more time to think. Karma leaned back his chair while Terasaka and his gang eyed him with interested. "Hey Karma , you sure about this ? That monster is pissed!"

"This is all on you , man !" Yoshida said evenly.

Muramatsu smiled crookedly. "Sure you're not better off holin' up at home ?"

Karma had the same empty expression on his face , his hands crossed with his chin resting on them. "Is none of your business , is it ?" He titled his head in the other's boy's direction , his expression were cold.

Some of the students made crewel remarks about him while others were doing their best not to tick him off. Terasaka gang feel chilled when they noticed the freezing atmosphere from the boy , is best for them to stayed away from him.

"You there , no loud noises during the test !" Korosensei scolded from the front.

"Tell that to your tentacles," Karma murmured.

He sighed and got up from his chair. He handed Korosensei his test and headed straight for the door. Korosensei took the test when he saw Karma slid the door open.

"A-Akabane-kun where are you going ?!"

"Out."

"WHAT ?! Y-you can't just leave ?!"

Karma tilts his head to the side with an innocent grin. "Watch me."

Korosensei's face was red with anger , placing his tentacles on his hips. "Get back here young man ! " he marched towards him , while Nagisa groaned in the background. "You can't break the rule-" one of his tentacles feet exploded. He looked down.

The pink pellets were scattered on the floor. "Anti-me BBS ?!"

Karma shot at his tentacles , Korosensei manga to avoid the two attacks felt four other tentacles fell to the ground as Karma stopped firing and lower his gun.

The class looked with their mouth agap.

Karma stopped in front of him. "Kill or killed is your choice." He walked passed him and put the quiz on the table. He stopped beside him. "There's always a reason behind," Korosensei tense up when he felt a dark aura around him , he snap his head around to see Karma slid the door open. "See you tomorrow sensei."

The class was left tense silence after his incredible assassin attack.

Korosensei disappeared into the sky as the scene changed to Kunugigaoka train station.

"Bye hoe !"

"Rio stop ! Anyway Yeah ! See you guys tomorrow !" Sugino waved good bye at the blue-haired boy and caught up with Nakamura who's laughing.

"Hey , look ! It's Nagisa !" Tanaka jeered , making Nagisa tense. "Right at home down with the E-Class."

Takada sneered. "Barf. He'll never get back to our class if he continues like that !"

Nagisa stared at the ground , trying to ignore them.

"Yeah ! The E-Class is the pits ! I'd seriously rather die then go there !" Then out of nowhere , a green bottled shattered above Tanaka's head , making the two boys scream and flinch back. Leaning the broken glasses closer to their neck as both of the boys felt fear crawl from their toes up to their body. Sending shiver down to their spine.

"Eh ? , you rather die you say ? I can help you out."

At that point the two boy already wished to crawl back their mommy's womb.

"Ah !" Takada ran away with Tanaka at his heel from the source of voice.

Nagisa turn around to see who've helped him. He didn't expect Karma to be standing there with a broken bottled in his hand."Humf, Pathetic." he dropped it to the ground as it shattered.

"Akabane-kun..." Nagisa said in awe.

"...say Shiota...?" Karma asked as they entered the subway station. "There's something I wanted to ask you about." They scanned their cards and walk into the station. "And no need to be formal. Just call me by my first name."

With Nagisa nodded his head. "T-then you can just called me Nagisa too." The bluenette squeak shyly.

Karma changed the subject swiftly. "Anyway , You know a few things about Korosensei , right ?"

"Uh , well , kind of...?" Nagisa followed Karma through the station.

"Does he get mad it if you call him an octopus ?"

"An octopus ?" The scene cut to show Nagisa's marked homework with and Octopus drawing on it."So if he's making jokes like that. I'd say the octopus thing is kind of his trade mark." Back at the train station Nagisa was smiling amusingly while Karma had a strange blank look on his face.

"Hmm," Karma put his a finger on his chin and hummed thoughtfully."....That gives me a little idea."

"What are you up to now , Karma-kun ?" Nagisa questioned , voice shaking up nervously.

The train cut across and shined an unnatural light on Karma's features, making him look demented as if his was literally fading from existence. "Nothing really , I'm just gonna pull a little experiment tomorrow."

"What ? What do mean Karma-kun ?"

He just shrugged. " Just adding a little fun."

🐙🐙🐙

The scene changed in a flash of light.

The next day class was on edge, no one talked to Karma and tried their best not to look at him. Which he didn't really mind as it gave him more time to think.

"Good Morning Class !" Korosensei greeted cheerfully as his students just stare at the front with a disgusted faces.

"Hm ? What's wrong , cla- ?" He froze when he saw a dead octopus on his desk with a knife stabbed into it's head.

"Sorry , My bad !" Karma rest his chin on his palm , he looked extremely calm. "I mistook it for you and killed it instead. I bring it here , so I'll dispose of it."

Korosensei sighed and picked up the dead octopus. "All right." Karma hid an anti-sensei knife behind his back. "Oh I see , the educated mode of him is on...." He sighed and slipped the anti-sensei knife back to his sleeve. "...guess I don't need these. "

Then suddenly the tips of Korosensei's tentacles morphed into high powered drills.

The yellow teacher disappear and reappear in a flash."Allow me to show you, Karma." He chimed , holding up a missile and various cooking sauces. "The might of these drill tentacles and the fire power of this missile I flinched from the Self-Defense Force ! " He said while Karma face still remain the same . A hot roll was shot into Karma's mouth.

"You see Karma-kun ," Korosensei presented the steaming dish. "What I do is tend to things and by the end of the day I'll have you sparking body and-" he was cut off by Karma who swallowed the takoyaki and stuck his hand out with a blank face.

"Nyua?"

"More."

Korosensei looked more dumbfounded. "....Nyua ?"

Karma sighed and sat back straight. "I already know what are you going to do. Plus , since I didn't have breakfast this morning..." He lick his finger and narrowed his eyes at Korosensei. " I'm feeling a bit hungry , can I have some more ? " They stare at him with a stunned look.

Korosensei blinked , blankly before snapping out. "O-of course Karma-kun !" He use 20 March speed and started to cooked. "You can have as much as you want !" hesitantly gave him the takoyaki and took a bite then chew it slowly.

Karma hummed. "Is a bit too salty," he said , slavoluring for a bit to study the taste. "the salt should half spoon instead of full spoon."

"I-um.." Korosensei nodded , robotically. "Then i'll remake it !"

The class watched in both weirdly and confuse at the situation.

The scene changed to Show Korosensei writing a maths problem on the black board.

"As you see , this number is left over , no matter what you do." Korosensei sounded as cheerful as ever. Karma was at the back staring at him."If this indivisibility is getting you down , Then you add this number here and you get 4x..." At the back of the room , Karma's eyes were cold as he with drew a pistol from his jacket pocket.

Karma aimed the gun and fired , but Korosensei moved just a fraction to avoid the bullet and then was in the exact same spot later.

"Oh , Karma-kun ?" Korosensei held up the gun. "It takes too long amount of time for you to took the gun out , I'm afraid. And since I had plenty of time to give you a little nail art-"

CRACK !

Korosensei was interrupted as the whole class heard four more cracks followed. They turn to see Karma fingers all bleeding as Korosensei "nail art" was now on his table.

"K-Karma-kun ?"

"I'm not really into octopus themed nails." He stated as he studies the nail in front Of him. Everyone just stared , horrified. "Sorry , but the color doesn't really suit me." He went on , staring as the blood slowly travel it's way down from his fingers.

"I think Red suits me more... " he started licking the harsh iron on his hand as the pair of mercury eyes stare intensely at him "...sensei"

With that , they all gulp nervously. Shaking with fear as they stare at the boy who continues peeling the skin off his nail like it was nothing , ignoring the both odd and concerned looks he was getting.

"Second period : Fourth Period : Home Ec *

"No.no.no. You are doing all wrong Sugaya-san , you're not suppose to cut the tomato like this !"

"You know what ? I'll teach you how to dice it , and -"

" no. Sugaya , stop mixing -Sugaya , no -give me the bowl ! NOOOOOOO ! "

" Sugaya-San !! Someone STOP HIM !! "

Yada managed to hurry up and took the knife away from the boy's hand. Then she started showing him the correct way to slice the tomato.

"See ? That wasn't hard. Now you tried." She handed the knife back to him as he hesitantly nodded and mumbled a soft apology.

He swallowed hard as he shove the tip of the knife into his tomato. Kayano who's also on his team watching the situation with a frown.

"Sugaya-San ....if the tomato have a mouth , I swear it'll be screaming right now." This made the boy pause , that's when Kayano took a chuck of onion and throw it at him.

"Hurry your flat ass up or I swear you'll be next !" She hissed.

"Hey ! I'm sorry okay ?! But don't insult my butt !!" He shook his bottom and smirk. When a glare came flying towards him making him tense before hurried back and cut the tomato while Yada tried to clam them down. Kayano pout and went back to work and something caught her eyes.

"What is this ?!" Sugaya gaze followed her finger at the pile of plates next to sink.

"Are you blind ? That's some plates."

"Why aren't the dishes in alphabetical orders ?!"

Sugaya snapped. "WHAT THE FUCK DOES THAT EVEN MEAN ?!"

"Well ? How p'd you two do , Fuwa ?" Korosensei appear behind them.

" Mmm , I dunno..Korosensei it has this kind of sharp tang to it." With that Korosensei started tasting her soup. "Let me try..."

"Why don't you start over ? Toss out that batch and-" Karma suggested flipping the soup , stabbing at Korosensei.

Korosensei dodged it.

"You forgot your apron Karma-kun." He stated revealing Karma having a pink apron stood in front of them.

"Go and don't worry about the soup I -"

Another voice pipe in. "It needs sugar."

"Why yes-" Korosensei froze and spun around. "Nyuya?" He watched Karma was standing beside the student , taking a full spoon to taste the soup.

He gulp up and hummed. "Like i've said , the sugar is not enough." He stir the ingredients, Chiba looked stunned beside them.

"H-hai !" Fuwa thanked hesitantly.

Everyone in class , beside Fuwa who were concentrating on her cooking stare at him when they notice the longer they stare , the more attractive and cute he is. "OH GOD !! HOW IS HE SO ADORABLE IN THAT OUTFIT ?!?! "

When suddenly the pink apron it self ripped apart by a incredible speed that human eye cannot see. The pink apron slowly slipped from his body as they watched itself fall to the ground , in pieces . The whole class watched , terrified.

*Fifth Period : Japanese."

It was an ideal spot for the red frog. Korosensei has tons of weak points.

"Why didn't it try to cross there ?" Korosensei ask the students as he continues mumbling about the subject.

Karma makes another move when he was stopped by Korosensei with a tentacles on his head. Korosensei started brushing , combing and blowing to Karma's hair yet the boy didn't react as it let it happen.

"Did you like my work ? Nurfufufu." Giving him the mirror as Karma stare at his reflection.

"Hmm..it's not bad but the style seems off."

"Nyu ?"

The boy just shrugged and look at the mirror infront of him. "But is good enough."

"I-is he not embarrassed ?! " The whole class had their mouth hang open.

The scene cut to the cliff.

Karma sat at the edge of a tree , hanging from a cliff as Nagisa stood behind him.

"Are you okay , Karma-kun ? " Nagisa poke his head out. "You run out of ide-"

"Hey Shiota-kun.." Karma trailed off and place both of his hand beside his thighs. "...would it ticked you off to die in some random place ?"

Nagisa looked over , questionably. "Huh ? What do you-"

Korosensei was moving towards them. "Karma-kun ?" His face had the green stripes again , rubbing his tentacles together menacingly. " Anymore Assassination attempt i'm always looking for a way to improve my students Nurufufufufu"

Karma let out a deep breath before he stood up. "Say Korosensei ? You're a teacher right ?"

"Huh ?" Nagisa cast him a curious sidelong glance.

Korosensei nodded. "Yes ?"

"And as a teacher you would risk your life to protect your students right ?" Karma eyes glinted.

"Of course ! That is my duty as an educator !" Korosensei replied.

Karma send a strange expression where they couldn't describe. "...Good , then I can definitely....." He lifted his gun and fell back over the cliff. "...kill you."

Nagisa's eyes winded in horror. "Ah !" He ran towards the cliff.

Karma was still falling and time seemed to slow down. Karma fell down towards the trees as a soft melody played in the back ground. When suddenly flash of familiar picture playing in front of his eyes.

The screen turned faded to black....emptiness....they all are dead...

A Circular Wood Cutting Saw Blade Discs were hold in a hand , drilling over the skin with blood splattering the concrete floor , the boy pierce screams shot through the darkness. People with white coat surrounded him. The men grinned in satisfaction but his face pale when the screaming immediately stopped. The Man stumble back , his knee weak. The cold , lifeless eyes which stared back at them....it chuckled , darkly.

It showed that Karma was falling head first to the ground.

He watched the last light of hope slowly swallow into him pitch of darkness.

Time sped up again , His body unfroze when he saw Korosensei's tentacles coming at him with March 20 speed , guessed what the octopus would do before he did it , as a sticky substance almost like a spider web appeared below him.

"Karma-kun !" Korosensei appeared underneath the giant yellow web. "Splendid job on the premeditated assassination starring yourself. If i saved you at the speed of sound , your body wouldn't hold out. But if I moved slowly , you would shoot me." The teacher appeared at Karma's side but the body seem to remain calm. "So I tried getting a little sticky."

Korosensei moves to the boy left side who hasn't said a word, "You can't shoot now Nufufufufu. Oh , and one more thing Karma-kun...." he looked at the boy. "Letting you die is not an option."

Nagisa was knelt looking over the cliff edge while Karma was sitting in the ground and Korosensei stood further back. Nagisa was shock to see Karma was surprisingly calm.

Karma shrugged. " I know ," He glanced up at their teacher. "Just doing some experiment."

"Eh ? "

"Experiment ? " Nagisa and Korosensei gave him a questioning look.

Karma stretch his arms in the air. "Didn't I told you , Nagisa ? Back at the station.." he sighed and looked over to them. "...I just wanna seems faith in you for being a teacher."

"Huh ?" Nagisa and Korosensei share a blank look before realization hit them. "WHAT"

Nagisa looked horrified. "YOU MAKE SUICIDAL ATTEMPT TO SEE HOW WE'LL REACT ?!"

The boy's face didn't change as he stared blankly ahead of the cliff. "Of course not, I just have my own way to prove something to people." He looked down at the edge of the cliff with his hands in his pockets as Nagisa stared at him curiously. "I'm sure everyone else does too, but some of them have their own ways that are more twisted than the others have shown. Even the same goes with a cry for help; that doesn't mean we're any less different from each other, right?" He then turned his direction towards the bluenette, and for the first time, Nagisa couldn't figure out what was going on behind that mysterious glint in those cold, golden eyes like he did with other people, Karma continued. "After all, there's a reason why I was transferred here in the first place."

Nagisa was struck silent as a memory of him going along with Terasaka's plan to kill himself with a BB bomb just to assassinate Korosensei flashed across his mind. Not fully understanding what he meant, both Korosensei and Nagisa carefully watched the redhead, who was now walking away, before they asked for answers as to what he meant.

"Just who are you?" A faded image of what seemed like a dragon's eye flashed on the screen. '....Karma-kun.'
