Assassination Classroom with a couple of characters from another property.

I don't own anything.

Apologies for the grammar. Still working on it.

Story Start

The assassination classroom was having a normal day. A normal day here would be strange for anyone else.

There was the usual, doing your everyday class work, hanging out with friends, plotting to kill your teacher who destroyed the moon a few months ago. Everything was good in the 'End Class'. The students plotting, the teachers teaching... assassination. Everything was going normally. Except, for one problem.

"I'm telling you, something isn't right about him." Said one Kanzaki Yukiko. Her and three others, Karma Akabane, Sugino Tomohito, and Kayano Kaede, who spoke up, "You might have a point. He does look kind of... hostile." Kayano said looking at Nagisa.

They were all behind a tree looking at their blue haired friend. Nagisa Shiota was sitting in the pool their teacher had constructed a while ago.

He had his pant sleeves rolled up to his knees with his feet in the water glaring at his reflection and muttering quietly to himself. Nagisa seemed to be in a bad mood, which was rare for him.

"Come on guys this is Nagisa we're talking about here. He probably just had a bad morning." Karma said as he gave Kayano a soda, "Go give him this he might just need a friendly face to cheer him up. Well, friendlier than me."

Kayano looked at the soda and then back at Nagisa. She took a deep breath and walked towards him. Calm and confident.

"Hey, Nagisa you seem kinda out of it." She handed the soda, "Here. To help you take your mind off things."

Nagisa looked up and took the soda. "Thanks." He looked down at the soda and proceeded to throw it a the group spying on him.

Smash

They had all hid behind the tree before it hit. Kayano was shocked. "This isn't my friend. What's wrong with him?" She thought frightened. She turned to him and 'eeped', he had darkness surrounding him.

"Tell them to leave me alone." Nagisa said as he dried his feet and put on his socks and shoes. He walked towards the old school house.

The others came out from behind the tree and watched him leave. They all looked at Karma with an 'I told you so' look. "Alright. Their might be something wrong with him." Karma stated the obvious. "Quit stating the obvious!" Sugino exclaimed.

They all sat down waiting for lunch to end, really trying to figure out what was wrong with Nagisa. "Maybe... it's his mom again." Kanzaki said. Karma immediately shot that down. "No. She's cool, I went to study at his house two weeks ago, they seem to be in a stable relationship." They all tried to think of what could be wrong with their friend.

"Maybe it's that time of the month for him." Karma joked. The two girls gave him a nasty look.

"What are you guys doing?" One Rio Nakamura showed up. Along with Bitch-Sensei and Yada.

"Nagisa is in a bad mood, and we're trying to figure out why." Sugino explained what happened a few minutes ago. They three were shocked, Nagisa was never violent.

"I'll try to talk to him." Irina said, "Maybe I could seduce it out of him." She smirked while fixing her hair. The teens had deadpanned looks on their faces.

"Yeah. I don't know Ms. Bitch, that might not be a good idea." Sugino said while scratching the back of his head. "Yeah, big boobs aren't gonna help in this situation!" Kayano exclaims. "Well, none of you have any ideas so..." she began to walk back towards the classroom and disappeared into the doorway. The group just stared. Kayano was glaring though. They waited for a good five minutes. Then Kanzaki spoke up, "Alright, that probably failed. Karma go help him your his best friend." Irina came out with tear down her eyes.

"Sniff...Sniff He called me 'A fake blond with plastic in her chest'." she then cried her eyes out. She walked away from the school house. By this time the rest of the class were watching, and were up to speed. And more than a little shocked.

"Girls go to care of the bitch. Guys with me, we'll talk to Nagisa. Itona go get Karasuma." Sugino suggested. They were all about to get a move on when they saw Nagisa walk out of the school house and down the mountain path. They considered going after him, but with that look on his face they didn't want to. Nagisa then turned back and glared at the class. One specifically. And continues down.

"So he's mad a Terasaka." Karma suggested.

"HUH?! What are you talking about? He clearly looked at all of us?" He snapped.

"I may know who he glared at." Said one of their phones. It was Ritsu. Their AI classmate. She had been on their phones watching the whole ordeal. "That comment Ms. Bitch told you about was only a small peace of what he said. The rest was much, much more vulgar." Ritsu shuddered. "Anyway by looking at Nagisa's eyes and their trajectory," she explains as she put a 3D model on everyone's phone, that showed Nagisa had his eyes on Karma, "You can see that he was glaring directly at Karma." Karma threw his phone, only to stupidity realize she was still on everyone else's.

The class surrounds him and stare. He begins to get uncomfortable. "Well?" They all asked.

Karma was feeling the pressure. He had never actually been cornered like this so, it felt a little unsettling. He then sighed. "So last week I uploaded that photo, of Nagisa and Kayano kissing... on... my... Facebook." He said rubbing his shoulder.

"WHAT!"

The entire group yelled.

The loudest was obviously Kayano.

"Why would you do that?"

"Sure. I'm an asshole to Nagisa, but I have limits." Terasaka states.

"Yeah, no. Almost blowing him up clearly shows you have no limits." Itona says. After a few minutes of scolding Karma everyone calmed down.

"So why would Nagisa be this mad?" Okuda asked and they all pondered.

"Maybe it had some sort of lasting effect?" Suguya said. "Maybe his mom saw it and freaked?" He shrugged.

"You might be on to something." Hayami said. "Anyone could see that image. Well, anyone who follows Karma."

"Speaking of which, why don't most of you follow me?"

"Not important." Most of the class said in unison.

All this time, Ritsu was debating, running the numbers in her head. Should she tell them? She promised Nagisa she would never tell. But now... she was conflicted. Should she keep her promise or tell them say they can help.

"Hey, Ritsu. You've been quiet for a while." Isogai said. "You got any suggestions?"

It was now or never.

"I... I know why Nagisa is angry."

"Why didn't you say anything?" Nakamura asked.

"I promised Nagisa I wouldn't say anything." She explains. "However, it seems that he needs help."

"Alright, lay it on us."

Ritsu took a deep breath. Or digital breath? Not important.

"Nagisa and his girlfriend had a fight."

"..."

"..."

"..."

"..."

"EH!"

"Huh!"

"What?"

"What?!"

"Nani?"

"Ya fuckin what mate"

After a long and tedious reaction from the class. Ritsu got back to explaining, or at least tried.

"How could he not tell me!" Karma exclaimed. "I'm his boy, bros before hoes, brothers from other mothers! I've never been so offended in my life."

Most of the class were ignoring him.

"Nagisa... has a girlfriend." Kanzaki repeated. She couldn't tell why, but she felt a sharp felling of anger.

"And I've never known about it." Nakamura said. "Kayano! Why are you guys fighting?!"

Kayano became red instantly.

"Why do you assume in his girlfriend?!" She didn't want to show it, but it was irritating her more then she let on.

"Am I no longer his best friend?" Karma said dramatically.

"It's always the quiet ones." Okajima muttered crossing his arms.

BONK

"Oh don't make it perverted." Kataoka scolded him. "You really think Nagisa is that type of guy?"

"I don't know..." Maehara started. "If we didn't know about this... imagine what else he's been keeping from us."

The class became quiet for a moment. What else could Nagisa be hiding? He hid his mothers abuse of him the entire time they knew him. Some of them thought about his skill as an assassin. He was practically a prodigy. Did he secretly train to be an assassin before he got into this class?

"Let's... not think about that." Sugino said. "Instead, let's figure out how to help him in this situation."

The class agreed, then one of them realized something.

"So who's he dating?" Itona asked.

They all paused and looked at each other. A large portion of the class moved away, leaving 3 prime suspects.

Kayano, Nakamura, and Kanzaki. The three girls blushed a storm.

"Hey! What's this about?"

"I... I don't... know why you left me here."

"I got over him!"

Nakamura blushed even more.

'I should've stayed quiet.'

"HA! You owe me 100,000 yen." Terasaka laughed at his group.

"MOVING ON!" Nakamura yelled as she walked away from the two girls.

"So it's between these two." Fuwa suggested.

The two girls, Kayano and Kanzaki were having an intense stare off. Both had a crush on Nagisa, one more than the other. It had been pretty well known to the class. Sugino tried not to break down in tears. In all honesty, the two had thought of each other as rivals. However, there was one problem.

"I mean, both reactions seem genuine. Really embarrassed and shocked." Toka said. "I don't think it's either of them."

"Could be dating one the girls on campus." Sugino suggested.

"UGH! I thought he had standards." Karma complained.

"Actually, she doesn't go to this school."

"Long distance relationship. That might be easier to solve." Karma said.

"She saw the picture you uploaded." Ritsu deadpanned.

Karma could feel his classmates glaring at him.

"So, where's is this girl 'tramp', so we can find 'kill' her and help Nagisa get better?" Kayano said venomously.

"Well... I can take you to where she goes to school. However... you should know..." Ritsu wasn't really sure how to say it. There was a high probability of Kayano destroying her phone.

"Well don't keep us waiting, Ritsu." Kanzaki said, with a dark aura around her.

"She's in highschool."
