Hey guys, so sorry this has taken forever to write. This is the start of a short flashback as to how we reach present day. Hope you all like it.

-3 years ago-

It was early in the morning and the school yard was empty. All that could be heard was the wind, sweeping its way across the field and collecting all the loose leaves. Karasuma was walking towards the dishevelled shack. He heard leaves rustling behind him, but thought it was just the wind. Suddenly he felt a sharp pain in his neck, he turned around to see a shadow holding the syringe that had just penetrated his skin. Karasuma fell to the ground as his legs gave way, forcing him to watch the shadow make its way into the woods.

In the woods, the whole class was standing around a petite girl, listening to her talk.

"I don't even know if it is possible, but I want to find a way to save Korosensei's life." Nagisa explained, her long hair flowing out behind her as she did.

"Save him? You mean find a way to stop him from blowing up in March?" Mimura asked.

"Where would we start?" Okano questioned.

"I don't know yet, but we'll work something out." Nagisa said shyly while playing with her fingers, hoping she had convinced the class with her answer.

"I'm glad you said something. If you didn't I was going to say the same thing." Kataoka said with a smile.

Slowly more students starting supporting Nagisa's decision.

"I hate to bring down the mood, but I'm against the idea." Nakamura said. "Korosensei said so himself, our relationship is one of assassin and target. I treasure that relationship too much to let it go."

An argument broke out between the class. Half of them wanting to save Korosensei, the other half wanting to kill him.

"It's always the talented ones huh? Always them believing that everything will just work out. You have the most talent out of all of us and you want to end the game now? What about the rest of us? What about those who are trying with everything they have, to keep playing with the little talent they have? Of course you don't mind changing the rules, you have already won. Isn't that right dear?" Karma said in a calm manner, the venom dripping in his voice.

"Wha- Karma! That's not what I'm trying to say at all!" Nagisa exclaimed, her voice portraying how shaken she was. "Besides, you have more talent than me anyway." She whispered.

"You see, that just pisses me off even more! You act like everyone in the class is like you! You don't respect how any of us feel about this!" Karma started yelling.

"Where is this all coming from Karma! I'm just trying to express how I feel about this…"

*SLAP*

Silence. The class was frozen in shock. Karma's eyes were red with fury, his hand still. Nagisa's eyes were wide with shock and fear, her cheek slowing turning red.

"Ka-karma, I thought you loved me! You said you would never hurt me!" Nagisa cried out breaking the silence, the tears slowly forming in her blue eyes. Karma remained silent, simply staring down at the petite girl.

"Now now boys and girls. As interesting as a fight may be, this is an assassination classroom, we sort out our differences with these." Korosensei said suddenly appearing, bringing with him paintball equipment. "It's simple, choose whether you wish to kill or save me and state your reason why. Then it will be a game of capture the flag to see who wins."

The class chose their teams one by one, each one giving a reason for their choice. The two teams split up and walked to their bases, waiting for Korosensei to find Karasuma and start the match.


"Nagisa, are you okay?" Kataoka asked the girl as the blue 'save' team walked through the woods.

"I'm fine, he didn't hit me that hard." Nagisa said, playing with a loose strand of hair.

"I know you are lying." Kanzaki whispered to her friend. "You always start playing with your hair when you lie."

Nagisa just looked at her friend in amazement. Even she didn't realise she did that! It also made her realise how much attention her friends payed to her. 'Maybe that's why Karma got so mad at me.' Nagisa thought to herself. 'Maybe I don't pay enough attention to myself and I didn't notice what I was saying was hurtful. Maybe..' But her thoughts were interrupted when she heard leaves rustling above them. She looked up and saw nothing.

"Hey Kanzaki, Okuda, did you hear that rustling?" Nagisa asked her friends.

"No, sorry Nagisa." Kanzaki replied.

"Maybe it was just the wind." Okuda suggested.

After awhile, the team had found a clearing to set up their base in. Kurahashi was putting up the flag with Yada. While Isogai and Kataoka decided on a game plan.

The rustling got louder and closer to the group.

"Hey, did you guys hear that?" Isogai asked noticing the sound and looking back at his team.

"It's probably just the wind man. The game can't start until Korosensei finds Karsuma Sensei." Maehara said reassuringly, trying to shrug off the idea they were being watched.

Suddenly a shadow appeared in front of them. Before anyone could react, the shadow moved from person to person at lightning speed. Nagisa could only watch her friends fall in front of her before she too fell, darkness engulfing her.


"Hey Karma, you seem to be awfully silent." Nakamura said, walking up to the red head who had perched himself on a rock.

"Wouldn't you be if you yelled at and then hit your partner?" Karma questioned.

"I suppose, though I wouldn't have left without saying anything. You love her and she loves you, she might have forgiven you if you apologised and explained yourself." Nakamura answered.

"You think I don't know that!" Karma yelled, the anger starting to return as he punched a nearby tree.

"So why didn't you?"

"I don't know. I don't even know where this rage against her came from."

"Look, this is war now. I don't want you leadership and judgment impaired by your relationship." Nakamura concluded.

"You're right." Karma agreed. "I can deal with this later. Chiba! Hayami! Have you located their flag yet."

Chiba and Hayami had found a tree to perch on and build their snipers nest. A vantage point from which they could see the entire playing field, with Hayami looking one side and Chiba looking the other. When Karma called out to them, the two looked at each other and Chiba started shaking his head.

"No sign of them yet." Hayami reported before staring out at the field again.

'Odd, I would have thought with both Isogai and Kataoka, they would have been organised by now' Karma thought to himself.

"Nyahh!" A cry pulled Karma out of his thoughts.

"What's up chief, can't find Karasuma sensei?" Karma casually asked as Korosensei flew into their base.

"Oh no, I found Karasuma. The only issue is…" Korosensei replied as he placed the lifeless body on the ground.

Almost immediately everyone went tense.

After trying to pull up the courage Okano asked, "Is he dead?"

"Thankfully not." Korosensei replied. "He's been sedated and I can't find who did this. For safety reasons, I'm calling off this game. Have you found the other team?" Korosensei asked with a sad tone, looking to the pair of snipers in the tree.

Chiba and Hayami looked at each other again. This time Chiba nodded and pointed out to his side of the field. Hayami's eyes widened in shock and slight fear when she followed his guide.

"What's wrong you two? Still can't find them?" Karma asked the pair.

Hayami visibly gulped before addressing the class. "We found where they were going to set up their base…"

"What do you mean were?" Nakamura asked, nervousness starting to creep its way into her voice.

"Their base is bare, the flag is up but all their weapons are on the ground." Chiba said, turning to the face the class.

"W-wait are you t-trying to say that…" Okano stuttered.

"They aren't saying anything. This is a joke, right?" Karma asked, sounding unsure with himself.

"I hate to say it, but I think half our class has been taken octopus." a voice said entering the base.

"Bitch sensei, w-what do y-you mean!" The class exclaimed.

"I found this in the staffroom." Bitch sensei said, holding up a piece of paper.

'Thanks for the new students teach. I promise to take good care of them.' the note read

"Who wrote that!" Terasaka demanded.

"I've seen this writing before, only one person can write like this." Bitch sensei started

"The shinigami…" Korosensei concluded.
