Nagisa's Prov.

"Hello there." Korosensei said, now having his disguise removed. Everyone stared at him in disbelief. I don't blame them. He is a lot to take in.

"What is that?" A girl with night black hair and light brown eyes asked. She was Maemi Nozomu. From what I remember, she was Kanzaki's favourite. She worked along Yuzuru Sayami as the camera girl. She showed to have an expressionless face with a monotone voice. "Is that our new teacher and classmates?" Another girl asked. She had long purple hair and gentle lavender eyes. She was Saika Sumi. She was sat with Amaya Eiko, the girl Ryoma likes, as well as the most popular singer in the R-Group, and Suiko Tomi, a girl with pale blue hair and lively blue eyes. From what I remembered, she mainly helped with clothing choice for music videos. "Are they the newbie's?" A girl with long, messy light brown hair that was half up and half down questioned, raising an eyebrow. She had two high pig tails in her hair. Her eyes were an ocean blue. She was Oki Ruka. "I think so." A girl with pale-ish dark red hair and bright green eyes said. She was Izayoi Imari. She and Oki Ruka were sitting together.

"Yes. That is us." Korosensei said waving his tentacles around. The rest of us stood there awkwardly until Karasuma-Sensei stepped forward.

"Where are your teachers?" He asked, looking around the room at all the students.

"I'm right here." A voice spoke. We all turned our attention to a desk, where a woman with long jet black hair and plum colour eyes stood. Her eyes... They had some sort of hoops in them. And near her pupils, her eyes were darker shade of plum. "I was sat here and you didn't notice me Irina. Now I'm shocked." The woman stated, placing a pale hand on her right hip. I looked behind me and saw Jelavic-Sensei's eyes went wide as she looked at the woman. She then ran to the woman, startling the rest of us.

"Erina-Nee!" She gasped with excitement as she suddenly hugged the woman with sparkles in her eyes.

"Nee?!" We all exclaimed in disbelief as Jelavic-Sensei let the teacher out of the hug. Even the R-Class looked shocked at what Jelavic-Sensei said.

"I believe an explanation is needed." Karasuma-sensei stated after clearing his throat as he folded his ar. "The name's Erina Gina, I'm part of the military defence, placed in charge of this class." The woman explained with a serious expression.

"Erina Gina? As in, the woman known to take assassination jobs when needed? You're a trained killer, what are you doing here teaching a bunch of kids?" Karasuma-Sensei questioned. We all looked at him. His expression was serious; however there was something in his eyes... I couldn't tell what it was. I heard a chuckle leave Gina-San's lips. My head turned back to her to see a smile form on her lips.

"I see my reputation precedes me. Yes I'm an assassin part of the military defence. Yes I'm teaching a bunch of kids, but you question why. Shouldn't you know? You're head of the military defence." Gina-San explained. She gave an expression that made it look like she was mocking Karasuma-Sensei, kind of making me glad I wasn't in her shoes. I turned my head back to Karasuma-Sensei who had a vein throbbing out of his head.

"If I knew then I wouldn't be asking. Now please explain yourself." Karasuma-Sensei said calmly. Although there was a dark aura around him, he sounded calm and collective. I turned my head back to Gina-San, who was leaning against her desk.

"Why else would the government bring a deadly assassin to teach a bunch of school kids when an unidentified creature is planning on destroying the earth? I'm here to teach the children how to assist killing the creature protecting earth of course." Gina-San explained, replacing her mocking expression with a serious one; however our attention was taken off this conversation as we heard a seat move. We all looked to see one of the students standing. Oki Ruka.

"Sorry to interrupt your little conversation but I think we deserve an explanation now." Oki Ruka stated, interrupting the two teachers as she rose from her seat, placing her hands gently on her desk as she looked at Gina-San.

"Didn't you know? They're the new students and teachers." Ayato Daichiro explained, making Oki Ruka look at him. She raised an eyebrow and Ayato Daichiro nodded with his eyes closed. "It's the truth. I was told before the others went on the trip." He added.

"So that's why Akita isn't here." A girl with dark midnight blue hair and purple eyes spoke. She was Aina Enju. She is known as the leader of the small group, AKA. There are three of them. From what I remember, they do a lot of country pop songs in the group.

"Figures; she'll probably be here in P.E." A boy with blonde hair and dark eyes said. He was Akashi Hina. He was part of the group, AKA. "Shouldn't Yuzu-Chan be here then?" Saika Sumi asked, looking around at her classmates. I then notice Amaya Eiko nod in agreement.

"She has a dentist appointment." Ayato Daichiro explained. "Man I feel for her." Akito said as lines appeared under his eyes with his face turning pale. "Yeah, only because you bit the dentist when you were younger; luckily Yuzu isn't like that." Ayato explained with a blank expression as he looked at his twin brother. "He had his fingers in my mouth! What do you expect?!" Akito exclaimed as he waved his arms around, which earned giggling from the girls in both classes.

"Hey, that guy with blue hair reminds me of Kuroko from Kuroko no basket." I heard Ai Eita whisper to one of his friends. Some reason, I think he's talking about me. "Well, you know what that means." Akito snickered. "Yuzuru is gonna be teased when she gets back." Ai snickered. How do I have anything to do with that?

"How many students are there?" Gina-San asked as she picked up a clipboard and pen. "27." Korosensei said. Gina-San looked at us as she raised a brow. "I think you missed counted. I only see 26." She stated. Korosensei pulled his phone out and Ritsu appeared. "Hi there!" She said cheerfully, smiling as she usually does. "So there will be 54 students all together." Gina-San said as she started to write on some paper on the clipboard. She then placed it down on the desk and red through it while bending down slightly. I looked at Okajima who was... Trying not to drool... But how she managed to do that in an instant is amazing.

"Just to warn you kids, her IQ is above 200. You can't pull any tricks on her." Karasuma explained. It's as if he knew what I was thinking.

"Don't we know that?" Ayato sighed as he leaned into his chair with his arms folded behind his head. "That's your own fault." Oki stated as she rolled her sea blue eyes. "Hey! Akito got me into it!"

"Don't blame me!" I looked around. The only ones who were here were Ayato, Ai, Akito, Saika, Oki, Aina, Hiedo, Amaya, Izayoi, Maemi, Suiko, Akashi and a boy with orange hair and brown eyes that were hard to see because of his hair. He was Katsu Natsuki, the last member of AKA. Shouldn't there be 27? There are only 13 and two we already know about aren't here so that makes 15, so where's the other 12?

"In case you're wondering, the 12 you don't know about aren't here because they're on a trip. They won't return until next week. Well, 11 of them at least. One will be here soon. She has a doctor's appointment." Gina-San explained. I jumped as she said that and looked at her. She was looking at me, which caused me to gulp. She then turned her attention towards Korosensei. It was like she read my mind. That's scary. She then walked towards Korosensei, her heels clicking on the floor.

"So you're Korosensei yes?" Gina-San asked. "Yes. Oh and don't bother attacking me with the anti-me knife in your boot. I'll dodge it." He said. "Hm just as clever as I heard." Gina-San smiled. She put her hand out for a handshake. She couldn't do the same trick Karma did when he first met Korosensei since Gina-San is wearing gloves. They shook hands, but then Korosensei's tentacle evaporated. My eyes went wide. How?! "For a smart guy, you sure are stupid to underestimate me." Gina-San said as she pulled up her jacket sleeve to reveal a hidden dagger, however instead of a real blade, it was an anti-Korosensei blade. "Well I assure you, it won't happen again Miss Gina." Korosensei said. "Just call me Erina. The students do." Gina-San said. She then turned to the rest the students of class-R, who still looked like they weren't sure on what to say to the current events.

"This is the creature Tristan and I have been training you to kill. His IQ is off the charts and he can go at Mach 20 and also, he will be teaching you here." Gina-San explained to Class R while pointing at Korosensei with a frown, showing that everything she said wasn't a joke.

"Heh?" They all asked as they tilted their heads with large eyes and their mouths open. "This is a joke, right?" Saika asked. Amaya shook her head. "Ama?" Saika questioned. Amaya looked at her. "I see..." What was that? She doesn't talk and I didn't see her jaw move. The bell then rang which made us all jump. It was very loud.

"That damn bell!" Aina exclaimed as she covered her ears. "What?! I think I went deaf!" Katsu shouted. "What?!" Aina shouted. The bell then stopped completely and we could all hear again. "I'll never get used to that." Erina said. She then turned to us. "Break's over. There are seats set up at the back for you. Right now is English, who is your English teacher?" Erina asked. "Me." Miss Bitch said. She sounded happy. "Oh? So you don't slack off and do nothing?" Erina asked. Miss Bitch then froze. "Good luck. These kids know what they're doing. They've made every teacher they had run for the hills." Erina said before walking out. I gulped. Are they really like that...?

"She makes it sound like we're deadly." Oki whined as she sat back down and slid down into her chair. "Well it is the truth. The last one was Akito's fault." Izayoi said. "It's not my fault that she doesn't know what you're a bitch in French means and thought I was calling her a cow." Akito said. "Aren't they both just as bad?" Hiedo questioned as he looked at Akito with his glowing eyes.

"Edo-Chan has a point." Saika agreed as she nodded her head. "Please don't call me that." Hiedo said quickly with a blank expression as he looked at Saika.

"Yo, you guys gonna sit down or what? Erina-Sensei already told you that the seats at the back are free." Ayato said. "Right, sorry." Yuma said. We all sat down in seats behind the R-Class and Miss Bitch introduced herself.

"Hello. I am Irina Jelavic, but you can call me Irina if you don't mind a first name basis." She smiled. That's fake and we all knew it. Hopefully the others can tell that this isn't the real Irina Jelabitch.

"Jelabitch?" Oki questioned. Miss Bitch had a vein pop out, but she smiled. "No, no, vic." She said. Why is she trying to be nice? "Um, I think it's actually bitch." Akito said. Miss Bitch seems to be trying her best to not break down. She even wrote it on the board to explain it to everyone.

"Why are you trying to be nice Miss Bitch?" Karma asked with a smirk plastered on her face. She lost it. "IT'S VIC! JELAVIC! YOU HEAR ME?!" She shouted. "Kinda hard not to since you're shouting so loud." Saika cried as she placed her hands on her ears. The others laughed, until the door opened and that Yuzuru Sayami girl stood there.

"Who are you?" Miss Bitch asked. She seemed annoyed. Yuzuru got out a note book and wrote on it. She then passed it to Miss Bitch. "You can't speak for the rest of the day because you've had a tooth taken out?" Yuzuru nodded as Miss Bitch read the note.

"What?! We need your voice!" Saika suddenly exclaimed as she stood up. Yuzuru got her note book and wrote on it. She then put it in front of her face where only her eyes were visible. 'Gomen' it said.

"Why don't you sit down, oh, and I'm Irina Jelavic, but call me Irina-Sensei." Miss Bitch smiled. Yuzuru smiled and nodded before going to a seat and sitting down.

"Miss Jelabitch, question." Oki said as she put her hand up. "It's Jelavic, and what?" Jelavic-Sensei asked as she slowly began to lose her temper once again. You could tell by the way her eye began to twitch. "Why did you call Erina-sensei Nee?" Oki asked. "Well you see, Erina is like a big sister to me. I've admired her since we were both students for our teacher. She as so amazing." She's going off the lesson and then I sighed.

"This is gonna be a long lesson."
