Chapter 21 - Plan Preparations

"Karma, you've got to listen to me!" Isogai cornered the redhead in the clearing where the class' civil war ended and the whole mess started. Karma was standing over a patch of grass which had faint smears of reddish dark brown with his back to him and fists clenched at his sides.

"Karma," He placed his hand on the other's shoulder, "Nagisa has amnesia."

"And?" Karma retorted with malice, not looking at him, "I understood that the second he said that stupid name. Please leave me alone."

"I can't, Karma," Isogai shook his head even though he knew Karma won't see him. "You know what he has, but not why."

"It's that stupid fit's fault. Maybe even the black veins'."

"Yes, that's the thing… we found out what those black veins are…" That got Karma's attention and he turned to Isogai with urgency in his eyes. Isogai smiled sadly; glad to have the redhead's attention but sad because he knew that it was not for a good reason.

"When Kayano and Itona visited Nagisa earlier, they had… a terrible reaction to him," Karma narrowed his eyes, something flickering in his eyes and Isogai knew that given a moment, he'll connect the dots. But he doesn't want him to start getting into denial. "They collapsed and started screaming about not wanting to listen or even telling something to go away. Nagisa was very scared, not understanding what is going on.

We got them out of the classroom, trying to get out of them what is happening and Kayano was crying about them taking Nagisa away from her and a disease.

Karma… Nagisa has—"

"Don't." Blazing golden bore into his eyes, and Isogai could feel the pleading behind the harsh tone. The begging not to tell him the one thing that Karma dreaded the most; that Nagisa had been experimented with that disgusting thing…

Oh, how he wanted to abide to those feelings, to laugh and say that there is nothing to worry about; that Nagisa is simply sick and will get better. But he can't and the both of them knew that. It was the only way they can help Nagisa now.

"Karma, Nagisa was injected with tentacles," Isogai breathed out sympathetically, gauging out Karma's reaction.

But Karma didn't react. He simply stared at the same spot he had been staring at before, body slumped, hands in pockets and seemingly dead to the world. Like an empty doll.

And perhaps he was… the one thing their class hated the most was those dreaded tendrils. It had taken over Itona, then over Kayano. It had made Koro-sensei into the ticking bomb that he is and now has a new plaything; Nagisa.

At that moment, he had hated Koike Masato with such a great passion that he felt an inferno building up inside of him. He took a step back from Karma and turned away from him, clasping his hands together to try and get his act together. To calm himself down.

But he was shaking with anger and bloodlust; he was itching to take a knife and stab Koike Masato until he was a bloody pulp and dead, his buttons had been smashed until all he could see was red. He had seen how this whole ordeal had been pushing Kataoka beyond her emotional borders, how Maehara was blaming himself despite not being close to Nagisa like Karma and Sugino, how slowly the class was breaking down because of the pressure and the unknown.

And it all started because one man decided that their classmate was nothing more than a toy to play with.

"Isogai, I never knew how scary you could be…" The drawling was faint and the humor was lacking, but Karma had talked to him, he had broken out of his stupor. That had calmed the class' rep significantly and he turned to the redhead with a strained smile.

"Well, I am a part of the assassination class, no?" He joked weakly, the hot angry fumes still causing his hands to tremble and his chest to tighten with an unfamiliar ache. Karma nodded at that, shoulders brought up in tension, brows furrowed and lower lip trembling, but the usual glint back. Isogai smiled in relief, they will be fine.

"So what's the plan, Ikemen?" Karma turned to walk towards the class. Isogai shrugged and followed him, heart slightly lighter.

"Well, Koro-sensei will know how to take them out without hurting Nagisa too much so we had called Karasuma-sensei and he told us that they had been discussing the plan with a friend."

"Hoh? But why the planning? Just take them out." Karma looked at him with confusion.

"Beats me," Isogai shook his head, "Could be that they need to be cautious because of Nagisa's amnesia or something like that?"

"Hmm… I really don't like that…" Karma then mumbled something to himself, eyes slightly widening as if he had realized something and took off in a hurry.

"Karma!"

"I won't let them do that!" Karma exclaimed and took a turn to go off the mountain, free running until Isogai couldn't see him anymore. The class' rep stopped, panting with his heart beating frantically. What had caused Karma to get so alarmed? Surely the plan won't risk Nagisa's health… right?

"Karasuma-sensei, Karma is pacing in the main room waiting for you to come back," Kurahashi reported to the man as he stepped into the safe house. Karasuma thanked her and opened the door, wondering what is going to happen.

"Sensei! You have got to calm him down!" Terasaka's and Maehara's voices welcomed him as he entered the living room, eyes widening at the scene unfolding before him.

Karma was being held back by the two, skin sickly pale and dark circles under his eyes which glared at him with pure unadulterated golden rage. He stepped forward and folded his arms. "Karma-kun, what is going on?"

"I am not letting you use this plan on Nagisa!" He yelled, struggling even more and if it wasn't for his fatigued body and sluggish movements, he would have freed himself and struck Karasuma.

That wasn't what was frightening. What was scary is the fact that Karma seemed to know their plan even though it was only finalized now. Ilana's input and ideas were simple and easy to conduct, despite their high risk but they decided that the other outcome would be worse.

So how did Karma find out?

"I do everything to protect you and I wish there was another way but—"

"'But' won't cut it!" Karma snarled at him and Karasuma was growing aware of the stares from the rest of the class who were sitting around them, shocked into silence from Karma's snapping. Karma struggled again, gaining his attention. "Nagisa can die from that stupid plan of yours! If you dare do that…" Here he stilled and glared at him with finality that sent shivers down his spine.

"I will assassinate you."

He stiffened at that, knowing that the threat is real, but he can't back down from this; this was for Nagisa's future. This was to release him from those terrible tentacles. Whether Karma liked it or not, Nagisa is dying and the only way to save him is to remove the tentacles.

He sighed deeply and squared his shoulders. "I understand if you want to assassinate me. If this will harm Nagisa-kun in any way, I'll give you this assassination happily, but right now you are not thinking about Nagisa-kun, but yourself. You are scared you will lose him that you don't see the bigger picture here.

Nagisa-kun is dying. Those tentacles are reaching his brain and already messed up with his memories. How long do you think it'll be until they'll reach his heart and shut it down? And even before that, how long do you think it'll take until he'll become a blood thirsty murderer?"

Karma didn't acknowledge his words, but he did stop struggling and his body slackened slightly. Karasuma took a step forward and prepared for the worst of the information he needed to give Karma.

"One thing that you must understand, we are doing it because there is no other option. The injection had a new kind of tentacles – it attacks the body and roots itself in it when it is dormant. If taken like that, it will destroy the host's body before it dies. And it seems to have no reaction to anyone but the octopus, which is the reason he had been avoiding Nagisa-kun lately.

Please think rationally and calm down. This is the best solution and I need your help."

Karma bit his lower lip, now using Maehara as a crutch since he didn't seem to be able to stand up on his own. Terasaka grunted and brought a chair for the redhead to sit on it. Karma sat down and hid his face in his hands, elbows on his knees.

"Sensei…" Maehara started and Karasuma nodded, "Some of us haven't seen Nagisa since his abduction and we are really scared that we won't ever see him again so if you think that it'll save Nagisa, please… save him…" Maehara's lower lip trembled as he gazed at the man with determination. "We will always be here to help him any way we can. So please bring him back to us…"

Murmurs and humming rose from the rest of the class, agreeing with the light orange head. Seeing the class' hope and pleading he stood straighter and nodded with all his dignity and pride.

"I will. Thank you for trusting me."

Nagisa was curled into a ball at the corner when Karma burst into the classroom. Blue snake eyes looked up in alarm and the small body tensed even further when the blunet saw that it was the redhead. Karma didn't seem to notice since he just strode to him and fell on his knees and reached out to him.

Nagisa squeezed his eyes shut, prepared for pain but was jolted when the arms simply circled around him and brought him into a tight embrace. His eyes snapped open and he looked at the redhead like he had sprouted a second head, but Karma didn't answer him, simply continuing to hug him.

Slowly, his body relaxed and he uncurled from his ball and leaned into the warm arms, hiding his face in Karma's shoulder. He was confused at Karma's apparent 180 degree personality turn but with what he saw in the mirror and with what he had been told, it would make sense.

He felt safe in those arms and he felt that he could just ignore all of his fears and insecurities as long as they remained like this. But a part of his mind was screaming that if Karma was acting like this, that something really bad is about to happen but he squashed it and let himself relish in the warmth.

"Nagisa, I need to tell you something about your condition…" Heh, he knew it. Nothing good ever comes without a price...

"What is it, Karma-ku—uh… K-Karma…?" The redhead stiffened and looked down at him. "I'm sorry, I still don't remember, but I don't feel right calling you like that so I… can I call you 'Karma'?"

Karma nodded and Nagisa attempted a smile. "So what is it that you wanted to tell me?"

"Well, you are probably going to feel very angry or even scared—"

"Karma… just tell me," Nagisa stopped the redhead and drew away from the arms, refusing to show his shivers and anxiety. "I am already scared. I saw Kayano and Sugino suddenly collapse just from seeing me. The only thing I can think about that connects them is the tentacles but that can't be, right?" He chuckled nervously, slowly quieting down when Karma looked away and his eyes widened, hand flying to his nape where he felt the bump. "No…" He breathed out, feeling weak and dizzy, the cereal he forced down his throat coming up. He coughed and suddenly everything came up, staining his blanket and his clothes. He choked on his coughs, the strong smell making him gag and breathless as he couldn't breath in.

"Nagisa, calm down!" Hands grabbed his shoulders but Nagisa couldn't hear him, his mind drawing a blank.

He has tentacles. He has those terrible tendrils which turned Itona and Kayano into vengeful monsters. He had been injected with those things and he doesn't even have any recollection of that incident.

No wonder he has amnesia; he probably was in so much agony. But then… why doesn't he feel any pain? His hand tightened on his nape and a sharp white-hot pain surged through his spine and he gasped, his other hand flying over the bump as well.

"Nagisa, does it hurt? Oi, answer me!"

It really hurts! He is such an idiot, of course you don't touch a tentacles' spot! Idiot! Idiot! He tried to remove his hands but then he felt something shift in him and a slithering noise vibrated through his skull. He heaved at the disgusting feeling, feeling hands on his cheeks and bringing his eyes to face the redhead, which seemed like a hazy image now.

"K-Karma!" He gasped, vomit dripping from his chin and sweat covering his skin, "I feel them! They are moving!" His voice was an octave higher with hysterics. "Get them out of me! They're disgusting! I don't want to hurt any of you!"

"Calm down, we have a plan," Karma's voice was firm despite the fear mingled in it. "Just take deep breaths. You are freaking out which is not a good idea right now. Just trust me on this one, okay?"

Nagisa nodded and buried his face in the white shirt which was dirty with his vomit and sweat. His hands were gently pried off his nape and he could feel a cool finger trace the bump which seemed even bigger before, oozing a sticky warm liquid down his neck and being absorbed into his shirt. His ears were ringing and a buzz was heard in the room which slowly lowered in volume the longer he let himself relax under Karma's soothing presence and massaging fingers.

"Don't worry, Nagisa. We will get them out of you and then we can finally return to our normal lives… well, as normal as assassinating Koro-sensei can be," Karma's voice regained its cheeky tone but even then Nagisa winched when a flare of pain stabbed his nape at the mention of Koro-sensei.

He pushed back more tears; it'll be fine, Karma said so. They will take those horrible things and they can go back to either saving Koro-sensei of killing him…

Just let it all be over quickly…

"I've got it!" Ilana exclaimed, standing up from her desk, where many papers and different tools filled with different liquids were scattered on it. She wore safety glasses and her hair was protected in a plastic hair covering.

Karasuma snapped from his dark musings and straightened at her enthusiastic exclaim. "You have got what?"

"What you asked me to make, idiot," She huffed and turned to Koro-sensei, who seemed very proud of her work, "Koro-sensei's body sample helped me greatly so I'm positive that it'll work. It is different than the usual cells I use, but along with Nagisa-chan's blood sample I found a solution for the tentacles' speed attack."

"Which is?"

Ilana raised a big test-tube filled with clear liquid that flashed light blue when the artificial light touched its surface. "A sedative. One injection will reduce the mobility of those disgusting things by two. We will give him two injections and that way will ensure a quick and painless separation."

"Unless this new tentacles serum is a whole new thing," Karasuma retorted. Ilana smiled softly at him, sadness in her eyes.

"Everything is possible, Karasuma-san. But it will reduce its mobility and that's what we need the most now. Anything else will be up to Koro-sensei because that's the most I can do…" She sighed and plugged the test-tube, placing it on the test-tube rack. She then took a look at her notes and her expression turned thoughtful.

"Ilana?"

"Wait a second. I overlooked something that might help us... just a moment..." Her face turned grim and she gave a small peak at Koro-sensei then at her small draft of Nagisa, eyes shadowed. Karasuma gave her a baffled look, but she shook her head.

"Perhaps it'd be better if you don't hear about this… you are a teacher after all… I shouldn't have even looked over them again..."

"Tell me," His voice was harsh and firm and she gave him a miserable glare, looking like a grieving mother.

"I can make a solution that will wipe out the tentacles entirely by destroying all anti-matter in the vicinity."

"But?" He knew that she looked like this not because it was perfect, but because that the consequences might be worse than the benefits.

"It'll kill Koro-sensei and… since according to you the disease reached his brain, the dark matter might be connected to him now and... wiping it out will most likely kill him as well…" She shook, hand crinkling the sketch of the blunet. Koro-sensei placed his fingered tentacle on her covered hair and she wept, face in her hands.

Karasuma looked away from the prideful woman to give her the space she needed. From his research, she loved children and volunteered in an orphanage sometimes. Knowing that your research could potentially kill a child must be so hard on her.

"Ilana-san, this is just plan C," Karasuma heard the octopus say softly to her, "I will make sure that Nagisa-kun will be delivered safely to his classmates. Trust me."

"Please," She whispered, sniffling, "Please don't let this child die, Koro-sensei. He had been through so much…" Karasuma looked back to see her wipe her eyes, back straight and eyes looking to the octopus with fire in them. "I won't forgive you if you do."

Karasuma silently promised to her –

"It'll work out."
