There were silence , a few of the classmate exchanged unsure look.

Hinano looked at Korosensei. "Sir..." she glanced at her teacher who didn't budged. "Do you want to play it ?"

"Not really..." Korosensei grimaced , tensing up when he realized what was about to come next. "..but I have to face it one day."

"It's going to be alright." Sugino said gently and gave a small reassuring smile. "We will all get through this and helped Karma." even his own hand were shaking ever so slightly.

"If Korosensei was there..." Kayano took a deep breathe , she was slightly shaking. "That mean Aguri...."

"Are you okay ?" Nagisa noticed , her behavior.

Kayano looked away , she sighed. "I know that Korosensei have told his story," her eyes narrowed to the Octopus. "I think I'll be fine."

Gakushuu looked down , sadly after what he had saw and some of them tried confront him but he just kindly brushed them off. "I don't need any confront."

Nakamura also noticed the expression on one of her friend and she tried her best to offered Nagisa a sympathetic smile.

"Well , Karma is always a close off person.." Kayano replied , putting a hand on the blunette. "...but we know he's strong."

Nagisa wordlessly smiled back , faintly.

Gakushuu wore a frowned , thinking back the memories of what he had saw in the screen. "Just how much he had been through ?" he thought , sadly.

Ritsu pressed the play button.

( He stuck for four years after he was captured , until the moment they first met.)

The little boy sat on the platform quietly. His leg dangling over the edge of his bed , looking down and staring into nothingness.

"Wow, that's a shock!" a woman's voice rang throughout the room. "You don't look like a ruthless killer!"

Kayano stiffened when she recognized her sister's voice.

The boy looked over to the other glass wall to see a man observed her , amused. He stood there , watching them talked , it wasn't long before the woman pointed his index finger towards his cell.

( That's when he saw them , he would see him from a distance and even though the boy doesn't spoke much.)

The woman shirt had a bone with cooked meat on it inside a circle. "The 8/10th" was written about it in blue kanji.

"DAMN !"

Bitch-sensei eyes widened. "Oh...."

"Holy shit !"

"Look at those melons !" Meahara yelled , earring a slap at the back of his head by Hinata. "Ow!"

Kayano looked outrage. "STOP DROOLING AND STARING AT MY SISTER WITH YOUR OGLING EYES YOU PERVERTS !"

Meahara cried silently when the shoe was repeating hitting his head. "This is abused !"

"I'm Aguri Yukimura." The woman introduces herself. "And that boy ," she turn back to the other Glass where she pointed. "is Karma." She smiled.

"Oh my god ! It's actually Ms.Yukimura !" Hinano exclaimed.

"Yeah it is," Kayano sighed as she looked over at Korosensei when she then realized something.

"Wait , so Human Korosensei had met Karma before ?" Nagisa asked , gaining some attention.

Korosensei paused , thinking about it. "Well...I don't know. I mean I've only been with Aguri but I don't remember any one between both of us and the mad scientist."

Kayano's brow furrowed. "Now I can 100% confirm that this octopus was the one she's wouldn't stop talking about " the started getting suspicious , trailing her eyes back at the screen. "Wait..then how come she never mention about Karma before ? "

( but sometimes the boy would try his best to communicate with the man along with the woman he knew the man was falling in love with.)

"Hey there , Karma." Aguri smile down sweetly at him. "It seemed like you have a new neighbor." The boy continued stare , mutely at her before turning his attention to the Man in the other cell.

The Reaper looked at him , curiously. "Can't he speak ?" He questioned.

Aguri just nodded her head , still smiling. "Well he can," she crouch down and place a palm. The boy seemed to noticed and slowly move his small hand against the glass , trying to match hers , so only the glass separates them. " but he doesn't really speak much."

The Reaper ( Human Korosensei ) observe the boy and the woman , the smile continued to glue to her face. "But he's a sweet little boy deep down if you get to know him , y'know ?" The camera Flashed to the red head who stare back with his big doe eyes.

The whole class immediately felt their heart melts.

"Awwee ," Kurahashi cooed. "He looks adorable ! "

There were serious nose bleed.

The girls have heart in their eyes. "SO CUTE !"

"Cute indeed." Nakamura took a picture in Sugino's phone.

"Rio !" Sugino tried to snatch it away from her hand.

Toka quickly wipe her nose and looked away from the screen.

Nakamura grinned , and shrugged. "This is just something we need to treasure."

Gakushuu quickly took out his phone too and Nagisa just smiled at their behavior, but soon quickly disappeared when he felt something coming.

( He never showed any emotion towards them , but he felt warm when they would worry about him.) The screen flashed a picture of Aguri chuckling and the Reaper smiling at her. ( He felt save. Loved. They hang around as if they were a family to him.) Younger Karma was shown , staring at them and his expression turn soft. The screen faded to black. ( Sadly ,that day come. )

The class looked nervous about what was going to happen.

"The Blood is too strong ," Yanagisawa voice out. "it'll end up killing and damaged our project." His subordinate behind , running around frantically and the alarm suddenly goes off.

Nagisa flinched. "Project.....?"

Korosensei could only watched , wordlessly.

"I never knew Karma's tentacles could be so powerful." Toka said , growing concern.

The pervious bubbly atmosphere turn cold as the students and and teachers stare at the screen is growing alarmed and some of them distress.

"That's it ! We're moving him away ! He can't stay here any longer." The man he had come to know as Yanagisawa stated as they restrained him in order to transport him.

Aguri rushed to him , blocking his path. "No you can't take him away !" she protests. "Please he's just a child , why can't you just let him be free—" Yanagisawa face scrunched up in anger.

"SHUT UP YOU WOMAN !" Yanagisawa shouted , shoving her to the side so she can clear a path for him as Aguri let out a squeak of surprise. "NOW GET OUT OF MY WAY !"

"Oh fuck you !" Kayano gritted her teeth , her fist trembled aching for something to punch. "Don't you treat my sister like that !"

Isogai frowned , feeling annoyed. "I swear to god , can this guy ever shut up and treat a lady right ?" he scowled , crossing his arm.

"Please can someone just kill this bastard already ," Tsuchiya rolled her eyes. "he's a goddamn freak ! "

"I can't believe his my brother in law !" Kayano frowned return , more deeper.

Hazama blinked. "He's a wha-"

There was a brief silence.

"Uh...." Kayano chuckled nervously.

"EXCUSE MEH ?! HE'S YOUR BROTHER IN LAW ?!"

"WHA-" Yoshida looked like he was having a stroke. "YOU- I-"

"That's it !" Sugaya raises his arm. "I'm done with this shit."

"What in the world is this ?!" Okajima yelled , grabbing his head like it was about to explode. "Some kind of anime ?!"

They heard a small crumble behind them , they turned to greet with a wall that's falling some bit of pieces.

"Since when there's a wall here ?" Nagisa questioned.

Fuwa strap her duct tape. "No need to worried about that."

( In order to lessen the Reaper's mentally pain , they brain wash him. Erasing the man's  memories of the child.) The imagine of the Reaper was force to wear the helmet , electric shocked through his systems as he screamed in pain.

Yanagisawa let out a laugh. "Let's see how long can you managed that ?"

Nagisa's tensed, feeling his bloodlust mount when the scientist on-screen laughed. Kayano stiffened, when she listened to Yanagisawa words, the rest of her classmates and Koro-sensei growing more disturbed. Ritsu kept her face away from the screen, clinging onto her friends as her anger started to threaten to bubble up as the scene played off from memory.

The screen faded away

( They took away the boy , separating them apart and forbid them from seeing each other ever again.)

"NO PLEASE !" Nearly all the students shouted.

Needles to say , the whole class felt furious was an understatement.

Yoshida frowned faintly. "No wonder Korosensei can't remember him..."

Kayano gasped in horror.

"You are going to pretend that child never exist." Yanagisawa pulled her in the corner , threatening her as she whimpered. "You are here to work , not to make friends , am I clear ?!" he stated.

"Y-Yes Sir." Aguri trembled , underneath his glare.

The screen faded away , revealing Aguri wearing a frown and the reaper noticed. ( The guilt she felt for lying was tearing her apart like a piece of paper.) Aguri sighed , staring at the empty room beside the Reaper. The Reaper noticed her stare behavior and looked towards at where she was looking , but was greet with nothing but an empty room.( and she didn't dare to mentioned about Karma in front of him.)

Korosensei felt a wave of sadness and guilt. "Aguri..."

It showed the boy was wheel in to a huge livestock carrier. Yanagisawa on the other hand , had a grinned on his face.

Sugino frowned. "This whole thing sound crazy."

"Yeah , but what else is new ?" Hazama comment , shrugging.

"No." Karasuma said dryly , pointing at the man. "This man is the crazy one."

"Not to mention Karma literally were a world-renowned assassin a year ago with a mass kill count, who took in the boy of the man he'd killed," Yada commented. "And Korosensei currently training a bunch of middle-schoolers to kill him. And meeting Takaoka and other madness assassin. "

There was a pause.

"....Wow..." Takebayashi checked his watch. "..since when did you have enough time to made it into a slide ?"

Yada shrugged , "Since the beginning , I guess."

"Uh..."  Nagisa narrowed his eyes at her and looked down at his own note book.

( While on the island , he was subjected to fiercer torment.) Akihiro who's another mad scientist was showed behind the glass , watching the boy who's been strapped to a metal platform. There was a strong constant current of energy flowing through his body.

"Higher up the power !" Akihiro command , shouting at them.

One of the worker pushed the lever , increasing the amount of energy that struck through the boy's body and flowing through his vein in a fast paced. His face showed that he was in immense pain , he was screaming in pain. His whole body jerked as he was been electrified , causing him to coughed out some blood.

The whole class grew alarmed.

"Shit !" Okajima swore , gawking along with the others.

"Why do they do this ?! This is absolutely unacceptable !" Sugino started to look angry.

The blue haired boy felt his shoulders shake , remembering all those horrible abused , torture and experiment that Karma had gone through. Wondering just how cruel the world could be , even though some innocent lives had been ruined by each kill the Reaper had made over the years.

( That one fateful day , he managed escape the world. ) The boy was screaming while he was trapped in the plat form , struggling with all his might. The power was overwhelming , creating a form of red energy and the whole Building began to shook uncontrollably.

"What's going on ?!" Akihiro was beginning to panic. Several of the cameras in his room simultaneously stopped working. "What's wrong with the security system ?!" he yelled at his team member.

"I don't know ! I-it's not responding !" One of them shouted back.

Akihiro quickly rush out the door. "His power is over loading !" , the equipment around him began to fell and shattered across the floor.

( the world was destroyed,) A imagine of a formally fully shaped earth exploded in space with a blinding white light, leaving nothing but a crescent shape in its wake.( ...and yet it was restored. )

( Due to not have the other few tentacles to balance his powers , his whole body started becoming unstable.) The camera zoomed out to outer space showing the Earth began slowly breaking apart. ( And it was that day it had lost control.)

His body glowed white as it released an explosion as it slowly destroyed the Earth , the explosion growing stronger as it pierced the planets surrounding and soon reaching to the Sun as well. Miracles happened , the screen slowed down , the time along with everything stopped. Every living things and machine , was completely frozen in place.

"Whoa !"

Okuda glanced at the bird who was unmoving in the screen. "Did the screen broke ?"

"How is this possible ?!" Mimura questioned in disbelief.

Nagisa started to feel sick , imagining every living and non living things just disappearing in the blink of an eye.

"Did he died ?!"

"This is just insane !" Isogai was pale. "Everything is insane !"

Kanazaki looked ill as she held herself tightly.

"Hey....little guy..." a voice said , lightly.

The world around them disappeared into nothingness , the creature from before held the boy who lay lifeless in his arm. Not a single drop could be heard. "...is not existence time yet..." It whispered into his ear.

Suddenly it showed Karma , standing between a dark space of timeline that's surrounding by endless of clock with each different size. Each of them were ticking away and most of them were broken into pieces , like someone had shattered it with their fist and blood splattering around everywhere.

The students gasp.

"WHERE THE HELL IS THIS PLACE ?!"

Ritsu hummed. "It seemed like he's stuck between a time line."

"Wait , That's possible ?" Fuwa asked.

Isogai smiled sheepishly. " I mean , anything could be possible right now."

"Heck yeah." Nakamura rolled her eyes.

Sugino shrugged and jerk is thumb over Korosensei. "We even got a 13March right here."

It took a moment when they realize Gakushuu was there too.

There were a long stretch of silence after that.

"Nothing." Hiroto gave a strained laugh , making the class president brow furrowed.

"M-MOVING ON !" Okuda squeal , causing the person beside her to jump.

Gakushuu rolled his eyes. "I already knew about your octopus teacher," he said , unimpressive. "Is all around the news , remember ?"

The E-Class glanced at the teacher then at each other.

"yeah we know " one of them shuffled nervously. "..but it still feel weird to see someone else know this besides e-class..." they smiled awkwardly.

Gakushuu sighed. "Just continue the video..."

Meahara quickly pressed the played button.

Karma stood up and looking straight forward , it showed the process he went through were never enough. The punches never stop and shattering never end.

( He promise forever but he never knew the prize. )

The screen crack and the clock was broken, once again. The glass cracked even more. ( is better like this. ) the broken part of the earth automatically fixed back it self. ( He doesn't care how long this will going to end.) After cracking it one last time , no one could see through it.

Karma was breathing heavily , his fits continued to bleed and the mercury eyes burned with determination.

"I will held on to the promise." The glass finally shattered.

The time started moving in reverse , the camera zoomed out away from the boy and outside of the world showing everything moving in backwards.

Some of them shut their eyes from the blinding light.

Nagisa clenched his head like it was going overload.

"Is fixed ?! "

The rest of the students watched in interest.

"Did everything just turn back to normal ?.." Sugino was sweating , seeing the time reversed.

"Karma-Kun..."  Korosensei was deeply worried.

The planet's and the sun could be seen regained back to their own form , speeding back into time travel where the boy hasn't transported away from the island.

Hirito eyes widened. "Dang it ! Now he's going back there !"

"No !" Hara whimpered , fearing to see another attack that come towards the boy.

"He's been through enough ," Terasaka breathed out. "the only thing we can is to protect him so he doesn't have to go through these type of shit again." He felt his chest grow tight like someone was squeezing his heart.

All of them looked at him surprised.

"D-did he just—"

"Woah Terasaka." Rio grinned. "Since you become a little genius ?" she playful ruffle his haired.

Terasaka growled lowly and slap her hand away. "SHUT UP EXTRA !"

Korosensei felt the feeling of pride in his chest. "My students are growing up so fast." But it quickly replace with fear and sadness when his eyes were in the screen again.

( It was then when he had turned 14 ) The screen once again showed the outside of the building where Korosensei and Karma once was trapped in.( that he saw the remains of the lab he resided in. )

The building that had been destroyed , it was deadly silence. One of the brick moved and suddenly a small hand stretch out from underneath those heavy bricks that has been collapsed. It moved around , searching and trying to get rid of the object that been forcing him down before forcing to break himself free.

Gasping for fresh air , he tiredly glanced around the damaged has been done. Dragging himself through his feet , he stumbled and trip on tiny rocks left and right. ( That's when he realized. )

(The final moment between the man and his lover. At long last , the man realized : her fault were also part of her charm. He'll use the time he has left to be a teacher like he promised. As he left he gave the man who had a fraction of his power inside himself , the tentacles asked him a final question.)

"Aguri !" Kayano felt like her heart had been stabbed and twisted. "NO !"

"Kayano !" Nagisa looked at her worried , he wrap his arm her as she lean on his shoulder and cried. "Shhh... is okay."

Her wailing were loud and muffled , Kanzaki and some of the girls gathered around her and shield their eyes away from the screen.

Korosensei breathe shook , becoming a bit unstable. Some of the Classmate noticed , they shifted closer to him and lean on him. He tensed but before relaxing , reminding himself that it was just his students. His family.

(The tentacles asked the man what he want to be.) The Reaper looked down at the woman's life less body. ( To be a guide. To be a teacher.) he stare down at the moment before he cried. The Reaper landed on a dirt hill, stirring up a large cloud of dust. His tentacles were larger, yellow, and rounded on the end.( Sometimes, I'll be wrong. )He looked up at the crescent moon in the bright sky. ( Sometimes my old self will bubble up to the surface, but I'll give it my all. I'll honor Aguri's memory, carry on her work the best way I know how.)

"It's not your fault sir..." Nakamura said , frowning. "Shiro was the one who made you this way."

"And that was his weapon that killed her..." Isogai said carefully , reaching out for his tentacles like he was holding his hand.

"Yeah..." Terasaka frowned , looking uncomfortable.

Korosensei felt wave of guilt , he started sobbing.

"Sir !" The students rush to him as he burst into tears.

The little boy had heard all the man's wishes as he hid himself behind the darkness and he watched the creature flew away. At the distance , he heard foot steps approaching making the boy dodged down.

"Aguri ?" The boy watched the girl with dark hair slowly walked over to the body and kneel next to her. "Aguri..?" When she didn't received a response , she began to panic. "Oh god , talk to me !" She shook her sister's shoulder. "Wake up ! Aguri please !" She began to cried her heart out.

The small figure didn't come out of his hiding spot as he watched the girl continued bawling on the ground.

He bit his trembling lips , his fist shook. "It's not his fault...." he said , but it came out barely a whisper.

They were surprised to hear his voice.

"D-did he just..." Okajima realized , pointing at the screen.

Nagisa raises both eye brow. "He...spoke.."

Kayano looked up and wiped her eyes which were now red and puffy from crying.

( But he couldn't bare to come out like this and tell her that.....all he could do was watched. ) The boy continued to stood there , silently. ( He hoped she could forgive him  , both the Man and himself ,) The picture of Aguri and Korosensei smiling down at the boy crossed his mind. ( the woman and the Man he had came to loved , also himself for accepting to become part of their family. )

The moon light above him illuminated him , the once broken moon was now surrounded by the night sky. ( He hopes one day...) He look up sadly. ( just one day she could learn the truth about his sister.) The wind gently touching his air.

"I'm sorry Akari...." the small boy felt lump in his throat , his leg gives up on him. ", I'm sorry Aguri , I'm sorry Korosensei...." he began to sniffled , clutching at the edge of his shirt. "None of this would have happed if it weren't for the power I was cursed with." He said as tears fell down his face.

"No..." Korosensei shook his head ,looking down. "...it's not..your fault..."

Hinano started crying and was wrapped into an embrace from behind by Toka.

Nagisa grimaced, looking down. "We're helpless here , we're just watching..."

Miura covers her mouth to a smother a sob , starting to cry followed by others as the music played softly on the background.

"It's true feeling helpless can feel a lot like a failure sometimes," Korosensei replied. "But protecting you from harm is one of the things driving Karma and me to fight." He gently patter Nagisa Head. "When we're fighting to protect the people and things we love , the stakes are higher and that's where their strength is."

The rest of the Class looked at the Karma in the screen with respect. Nagisa's eyes stung a little bit , blinking quickly as he rested his head on Korosensei's side.

Itona swallowed thickly ,trying to hold back his tears.

Gakushūu just wanted to barge in to the screen and held the boy tight , safety in his arm.

( He has remained in the shadow for who knows how long,until the fateful day.) The screen flashed to a Woman and a Man in a suit , sitting in the office. ( He was asked to go after the super yellow creature.)

"So...." , Hazama stare at the screen , sadly. "..that's the reason....he was in E-Class in the..."

"Because of his past... " Karasuma and Korosensei finally understood. "That's why he decided to transfer here.."

The students also realized the pattern.

"No wonder he looked so badass in the first place." Nakamura pointed out , giving a strangle laugh from crying to lighten up the mood.

"Just what the heck you're talking about ?" Mimura frowned , raising a brow at her. "He's always badass."

There was a lot of agreement.

"He's awesome." Kayano grinned , struggling to dry away the tears and remembering the first time Karma came.

Gakushuu nodded , feeling his sadness a bit waver.

( Looks like I finally get to see you again ,) Karma grinned down at the top of the stair , observing the students who's training for P.E and his eyes landed on Korosensei. ( too bad you won't remember me. ) He had come to class to see how he changed them. He was pulled into a new world , becoming friends with classmates and slowly starting to care for them.

The image of Karma standing still , every thing around him was nothing but glory red and darkness. Whispered and gossip started to echoed , surrounding him.

( Akabane Karma , who are you ? )

It flashed a picture of the whole Class who's turning away while Karma stood alone , completely facing the opposite in the darkness.

( What's he hiding ? )

Karma voice boomed behind a photo. "I get to keep an eye on him....." Itona face was on the screen. "...so they don't rip him apart." The second with his tentacles had come.

Itona grimaced , looking down as Terasaka group shot him some worried look.

Bitch-sensei lowered her head , looking warily.

Korosensei sighed , feeling his dread grow , the years coming back with each good memory clouded with his mistake.

"There must be another way to help him," Nagisa reminded their teacher and class who was growing more sadder. "You taught that people can change....even if it's easy. Karma deserve to be treated right !"

"Yeah ! He may not be fully human," Tsuda commented. "yet he saved us and got through so much pain and now is the time we help him."

"I mean, I agree but how ?" Hiroto frowned.

Nagisa looked down , sighing. "Karma always helped us to get through all the mess , Now is our time to stand the ground."

"We'll find a way," Kayano said , smiling. "we'll always do."

( He had taken the majority of their pain upon himself. Suffering on it's own for the sake of all of them because......) The picture of Korosensei and Aguri flashed on the screen. (....he knew how much this meant both the man an the woman so much. He willing to bare all the pain inside him and for the people he love.)

"If you don't get the tentacles back ," The Grim Reaper voice out. "you'll die before the teacher does." ( They made promise and Grim told him he would let Korosensei kept his tentacles. )

"WAIT WHAT !?"

The students baulked , while Korosensei sighed in relief.

"Oh , thank goodness," Korosensei wiped his tear. "He's still here."

"W-what ?!" Nagisa looked confused.

"Hold up ! What is he doing here ?!" Hara questioned.

"He's alive ?!" Sugaya asked.

Some of the teachers and students started choking in shock.

"I AM CONFUSION."

The other looked at the screen in surprise while Ritsu smiled faintly.

( The future Grim and himself , they both knew about the plan. This is their secret and now it will only be his own secret to go back and save them.)

Grim looked down , and grimaced hearing the boy's own words. "Even if he does live , I don't think he'll like the cost..." the boy said lightly. "..I know my time will probably end before he can even had a chance to protest."

"Assassination or not...." He turned toward the Man. "..one of us has to die." Grim smiled sadly as he listened. "And I'm not sure I'm willing for it to be him.."

"I'm sorry.." Grim apologize , still looking down.

"Wait..."

"I think I'm getting a headache." Gakushuu pinched his nose.

"Can someone please tell me what's going on ?" Mimura said , rubbing his head. "This all looked so complicated and confusing."

"So is Grim a good guy or a bad guy ?" Sugino questioned.

Korosensei smiled faintly. "I think he had learn his lesson," he stare at the younger boy who were once his student. "Karma had lead him to the correct path." A felt of proudness spread in his chest.

( The class civil war was coming close. But he knew that maybe there's still a chance.)

"No." The boy said , determined. "I won't let anything happen to both of you."

Grim frowned. "But Karma—"

"No. I will fix this." The boy said a bit louder, cutting him off. "I will help you and both of them to come back safety again. I will not give up on everyone," he pointed at the Reaper. "including you."

Grim was completely caught off guard by his word.

The boy sighed."I know it was not your fault," he said softly. "you didn't choose to turn out this way and either me , Korosensei , Aguri and everyone else." His eyes held gentleness. "I promise that i'll save you too."

"Wait...." Okuda frowned.

"Karma..." Muramatsu looked at the heart broken expression on most of Class E's faces and then the screen. "Is....is Karma going to die ?"

The Class tensed up.

"No !" Gakushūu suddenly exclaimed , making them jump. "We will not let him !"

Kimura looked panic and join in. "Yeah ! We'll save him !"

"We'll definitely !" Terasaka said , putting a hand on Muramatsu.

Hearing his words , the Man couldn't help but sighed as he stare down at the boy.

"Very well then...." The Grim Reaper smiled faintly, defeated. "but just be careful. I don't want to lose you...." he wrapped his arm around the boy and pulled him into a hug. "....and so does all of us."

The boy closes his eyes and gently embraced him back.( Even if The Reaper had done many things atone for sins he had committed, yet they could forgive him without hesitation.)

( Slowly , he had started to care for all of them along the way , and him....)

"We love you , Karma."

"I love you too."

( He loved them all dearly, ) It showed the boy smiling gently into his chest , slowly the imagine of E-Class , the teachers , Korosensei and even Aguri appeared and was also there embracing the boy. (more than anything in life. Same goes with them all.)It zoomed in to see the peaceful face of the boy sleeping. (He slowly starting to drown in them , their care for him , their protective fledglings , their light.)

The screen zoomed out to the present ,the Class blinked , started wheezing and coughing from the dust they had breath in.

"W-what happened ?" one of the student wince.

Nagisa sat up , rubbing the pain away from his head. "Ow..."

"Is everyone okay ?!" Karasuma shouted , rushing towards the students.

They noticed they were all outside of the bubble.

Kayano winced a little , sitting up. "Y-yeah."

"Guys , look !"

The other turn towards the sky , their eyes winded briefly at Karma who shot out his arm and grabbed the Shinigami 2.0 tentacles , it result immediately melt into his touch and starting to dissolve into thin air leaving his body. It turn into tiny balls of light and they floated towards the sky. Lowering the Shinigami 2.0 in his tentacles inside the bubble so they won't capture him , it reveal the man had returning his own human form. His face and skin was fixed back completely, and look like how he used to look like before the skin was peeled off.

The light still surrounding them , yet they never felt such cold darkness.

"He's willing to sacrifice himself for Korosensei." Takebayashi frowned , looking up as light faded into a ring that surrounded the E-Class mountain.

A guard made a run towards the boy , but when he hit the edge of the right it send a wave of strong force and threw him across the ground.

"How do we get in ?!" One of the soldier growl , shooting it. The others began gathered around , hitting the bubble.

Some of the E-Class noticed that only themselves , their teachers and Gakushuu were inside the bubble along with Karma. The students were still looking up at the boy , remaining still.

Nagisa watched in fascination along with the others. "Karma-kun..."

Karma stood there , almost seemingly lifeless and soon the circle light at the center slowly turning smaller until everything turn dark. His tentacles started drifting away and his whole body started returning his human form , the gravity immediately cage him and at that moment his body relaxed , he started to fall.

Panic began taking over their faces.

"OH MY GOD ! KARMA ! "

Kanazaki eyes widened in horror. "Ah !"

"HE'S FALLING !"

Koro-sensei's immediately flew up the sky , his eyes watered. "He's still in there. Just a little." He was trembling.

Karma fell down towards , as a soft melody played in the background. Everything turn slow motion as the Class were sprinting like no tomorrow , hoping to save him. Korosensei used his speed to reached out in time and quickly caught the the red head with his tentacles before he could hit the ground. "I got him !"

Gakushuu breathing was shaky. "KARMA !" he yelled and ran towards the boy.

Korosensei lower the his tentacles , a soft gasp escape him. The Class made it in time a little later , their heart immediately ache after seeing the terrible sight.

"Oh god.." Kanazaki breathing was shaky , she covered her mouth.

There laid Karma in Korosensei's tentacles as he kneeled next to him at the hill , the boy's eyes were streaming red tears. Blood trailing every part of him , his eyes , nose , mouth , ears and body , he was completely lay in a pool own his own blood. He looked at everyone , with the one eyes were shut close. His face were pale , his breathing shallow and he looked completely exhausted.

"He looks so fragile..."  Korosensei stare at the boy , looking as if he was unable to process what had happened.

"It's his time to go." A voice caught their attention , they turn and gasp when they saw it was the creature who's residing inside Karma's body , also his mind the whole time. "His mission has been completed." He was now nowhere near Karma 's body , instead he was transparent and floating on thin air.

"A-Are you serious ?" Okajima asked. "There's nothing we can do ?"

The creature kept silent , hanging his head low. The students one by one dropped down to their knees.

"NO !" Hara screamed , making some of them jump. "You're lying ! You can't do this to him ! To us !" Tears frantically running down her cheeks.

"Yeah !" Meahara join in. "We didn't spend a year together," he clenched on his own chest , feeling the stabbing pain in his heart. Years of Memoriesof E-Class flashes celebrating together at Final End of Term time. "trying to kill Korosensei ," Karma compliment Terasaka after Terasaka finally realize his mistake."bonding and having fun," he cried , shutting his eyes. Another picture of Karma smiling at the Class for the very first time."JUST TO LOSE KARMA IN THE END !"

Ritsu kept her emotion under control , her hand hovering to the back of her head.

"If I had saved him , Karma wouldn't be in this much pain." Korosensei's thoughts blurred on hysteric when the guilt grew unbearable as he stare at the boy in his tentacles.

"We can't lose him !"

Nagisa's eyes filled with tears as he thought back too many memories from the start of the school years. Korosensei took him and Karma to Hawaii. Karma helped him to get his courage up to defeat Takaoka.

Hinano burst out crying. "Please save him !"

Nakamura swallowed thickly , not bothering to wipe away the tears that continue fall like water fall.

Kataoka and Isogai covered their faces with their hands. Their shoulders shook as they cried.

Koro-sensei's shoulders racked with sobs as something inside of him broke, like his heart had been ripped out and mangled. "I'm so sorry..." a horrible image of his apprentice as a boy, stabbed through the chest while he held him. "I killed him..." he whispered brokenly. "I killed my student. My student."

Sugino had trails of tears down his face , Kanazaki cried quietly , tears falling down her cheeks. She covered her mouth with a fist , grasping her wrist with the other. Okuda didn't bother trying to keep down the volume of her cries.

Karasuma blinked quickly , subconsciously squeezing Bitch-sensei's hand when she was crying on his shoulder.

"C-Can I hold him....?..please ?..." Gakushuu voice faintly boomed out, catching Korosensei's attention. Korosensei stare at for a moment before slowly turned around to the A-Class president , he silently passed the boy to his arm.

Gakushuu carefully held Karma in his arm , like a fragile glass , he felt a swell of sadness when he saw his beloved was dying. He gently trailed his thumb over his lover cheeks , tears filled in those violet orbs. He held his hand , softly and sniffled. " Isn't there something we can do , my love ?"

Karma looked at him , quite for a moment before smiling with bright tears. "I'm sorry..."he whispered brokenly. "but there's nothing it can be fix..."

Gakushuu shook his head , tears running down his cheek and not wanting to believe this cruel reality.

"No , please.." Toka choked up , closing her eyes tight.

Okano's faces was trembling. She had tears in her eyes. She didn't respond with more than a hum , knowing that if she spoke , she would start crying and wouldn't be able to stop.

Rio swallowed a lump in her throat and let out a shaky breath , feeling sick.

Karma's voice shook ever so slightly as he spoke to his class and his lover. "It just fate....." a soft smile took over. "...it just how it is.." Kimura struggle to keep himself from crying , Hinano cried more and was wrapped into an embrace from behind by Mimura.

Fuwa choke up and buried her in her hand , while Oota patted her on the back.

"The... only way.." Karma swallow hard , trying to get the air into his lungs. "..would be for me....t-to..get my tentacles back... " he said , breathlessly. "....but that's a possible chance it'll lose control and kill him." The screen showed Hara sobbing. "He'd d-die....before I could." Nagisa sniffled , trying to control his sobs as the feelings came and washes over like a river tide. "And I'm not willing to sacrifice him..ever again....no matter how much he complains."

The mountain was filled with the sound if fading sobs and the music played , the others following after holding onto the boy hand. Nagisa scribed , shaking all over as he clung the fabric of his shirt. As If the whole world through the board cast , all sobbing and crying for the kind boy.

"Please wait a moment...." The Class directed his attention to see the Grim Reaper who stood in front of them , looking a bit hesitante. "I-I know..I did a lot of terrible thing in the past..but please listen to me.." he said , lowering his head. "...I don't seek for forgives but I think I can help." He looked straight at them , holding eye contact with their teacher. "It might be a bit risky and I'm not sure Karma would agree to it."

The class stare at him , hesitating to trust the reaper.

However Korosensei shut his eyes tightly , failing to fought back his tears. "I'll do anything ! Anything !" His whole body tremble. "I'M NOT WILLING TO SACRIFICE ONE OF MY STUDENTS AND WATCHED THEM DIE BECAUSE OF MY MISTAKE!!" More tears tempt to escape.

The whole class stiffened , the others started to look the same , dread and bawling their eyes out.

The Reaper sighed. "Because of the side effect , in order to save both Korosensei and Karma.." he paused , the others could tell he was hesitate. "...Karma needs to be the one to end your life."

The class stare at him , surprised. "I will keep you alive,"The creature who's stayed inside Karma spoke up , their attention turn to him. " In order to reform your human self , and return my tentacles back to Karma, but..." he stopped , tensing a little.

"but what..?" Kayano felt a lump form in her throat when he saw the creature expression.

"....but it's crucial he hit's your heart right in the centre to save everyone and Korosensei, If he missed......." The creature paused. "there's a chance neither one of you died...or the whole world along with it..."

Some of them were hesitant in , but their face change to determination when they saw the condition of Karma was in.

Karma coughed , grimaced in pain. "That's impossible—"

"Please Karma...." Korosensei voice boomed over the surroundings. "Do it for me," the screen shifted over to the class , who's filled with tears. "for us ," his voice shook immensely through the sentence then it flashed to Gakushuu's teary face. "for the one you loved."

"You can do it Karma-kun..." Kayano whispered , lips trembling.

Mimura covered his mouth to smother a sob.

Karma sighed as he saw the mess of emotions left , a swell of sadness sting in his chest. He slowly turned to the Reaper , and nodded weakly. "Alright..."

The class felt a wave of relief , hearing his words crease a small smile on their face.

"First Korosensei in order to do it, " The Reaper instructed. "I need everyone to please pinned down his tentacles."

Korosensei sighed , smiling. He nodded , following every step the reaper said , before laying on the ground.

"This is it. This is our answer."

The students stood around Korosensei , kneeling down next to his tentacles and holding them down.

*Korosensei's weak point #33 : can be capture if everyone holds him down*

The Reaper held onto the half conscious teen who struggling to sat up , leaning against him. Korosensei stare at boy , worried and decided to place his head beside him but a pair of hand stopped him. Korosensei inhale sharply in surprise, when Karma gently held his head to lead resting on his lap.

Karma took a deep breath and stared down at his teacher. "Are you...sure ?"

His teacher smiled gently. "For your sake, Karma-kun." Karma didn't said anything , he steadily positioned the knife over Korosensei's heart.

Kayano and the others send a worried glances at the boy who had a hard time to keep compose. Gakushuu stood up , catching some of attention. They watched him walked over to Karma and kneel down beside him.

Karma turned to him , just in time when Gakushuu remove his bangs and place a soft kiss on his forehead. The whole class looked in awe, and surprise. Gakushuu pulled away and smile. "I'll be waiting for you, my love."

Karma stare at him , smiling softly before Gakushuu slowly walked away , not break eye contact. His eyes were gentle as if it was telling him that everything will be okay.

The Reaper handed him a green knife , which Karma was a bit hesitant to took it when the Reaper place a hand on his shoulder and send him a reassuring smile. Karma paused , before his whole body relaxed a little.

The flashes back replay in his mind. "Please Karma...." Korosensei voice boomed over the surroundings. "Do it for me," the screen shifted over to the class , who's filled with tears. "for us ," his voice shook immensely through the sentence then it flashed to Gakushuu's teary face. "for the one you loved."

Those words echoed in his head.

He finally understand , he thoughts back too many memories from school year. Korosensei took Nagisa and him to Hawaii. Okano , Kataoka and Isogai tried to stab a motion sick Korosensei in the train in Kyoto. Nagisa showed something on his phone to Karma , Korosensei , Fuwa and Kayano.

The funny memories of Fuwa , Sugino , Nakamura , Kayano , Meahara , Isogai , Okajima trying to peek into the shower and get caught by Karma. Korosensei's tentacles were red and he flung them around around when Karma and the students accused him of being scared after first semester midterms.

The boy took it barely able to stay conscious, but he did it for the one he care about ,the one he love and love him , the one who wanted him to live.

He thought about Gakushuu gently hold him and kissed him under the festival light. The students rushed at Karma and Nagisa after they returned from space. Nagisa , Okajima , Sugino and Meahara stare at Karma , open-mouthed with Korosensei taking a picture. Karma smiling for the first time in years , creating a massive nose bleed from his classmate.

Karma stare at the crescent moon tie. "Gratitude , regret , appreciating and accept. I thought when this mission was finished , they wouldn't need me to be here anymore." Karma steadily positioned the knife over Korosensei's tie. "But then they prove me wrong again." It was getting harder to breath , black spot slowly taking over his vision and drowning every light it see. "I've thanked them with all my heart."

"Now !" The Reaper instructed as Karma raise the knife , and gently plunged the knife into Korosensei's heart and a white energy was created , illuminated the whole universe.

The screen faded to white.
