This is my first fanfic, so I hope you like it! Sorry if I can't get the characters right with their personalities. Line breaks will be used for time skips and POV changes, just so you know.

"So we're getting a new student today?"

"I wonder who it is!"

"First Karma, now them?"

Class 3-E was filled with conversation. News that a transfer student was coming to their class made them quite excited. More people to help them assassinate Koro-sensei. Just then, Koro-sensei came into the room. "Now now class, I'm guessing that you all know the news, but we are getting a transfer student. Before they come in, I would like to do the attendance.

"Isogai?"

"Hai!"

"Excellent! No absentees today! Now, here is our new student. Please, come on in!" The door slid open as the student walked in.

"It's nice to meet you, Erina." the yellow creature said to me. "It's nice to meet you too sensei. I hope we get along together." I said with a smile. "Please, come on in." I entered the small "school" and followed my new teacher. "Now dear Erina, you don't have a last name?" Sensei asked me. "No, I do not. I was raised as an orphan, and I don't know what my parents names are Sensei." I heard sniffling coming from him, and peering over, he was crying.

'Just what is up with this teacher?!' I thought, creeped out. We soon arrived to the classroom, and Sensei dried his tears off. "First of all, please call me Koro-sensei. It's what my students call me anyways. Second of all, please come in when I tell you to. Also," He handed me a sheet of paper. "Here is a class list for you to remember." I nodded and grabbed it before leaned against the wall, out of sight as he entered the classroom.

I heard him do the attendance, and shortly after, I was called in. Taking a deep breath, I slid open the door and entered the room. Everyone looked at me, and I simply walked to where Koro-sensei was and introduced myself. "My name is Erina, the new transfer student. I hope that we get along well and assassinate our teacher." I said bowing.

Looking up, I noticed a few students of interest. A boy with light blue hair, a boy with red hair, and a girl with aqua hair. The girl seemed to be faking something, though I couldn't tell what it was. "Right! Koro-sensei, I have a present for you." Taking out a necklace, it had a nice gold chain and a yellow pendant that was quite heavy. "Don't worry, there's nothing wrong with it." I assured him, and he clipped it around his neck. "Thank you very much Erina." Going to the seat that I was assigned at the back, I sat next to the red haired boy.

"Are you sure that there's nothing wrong with it?" he asked. Smirking, he seemed to get the message and grinned back. "The name's Karma Akabane, but just call me Karma." "You already know mine, it's Erina." We grinned at each other before turning our attention to the lesson.

It was now lunch time, and time to put my plan into action. I had told Karma about it, and he happily joined in. It was a nice day, so we would be eating outside. Karma would distract Koro-sensei, and I would detonate the pendant, which I had painstakingly put Anti-Sensei BBs inside.

We filed outside with our lunches and we sat down and ate. Karma and I quickly finished our lunches with a few other people and he introduced the others to me. "The blue haired boy is Nagisa Shiota. The aqua one is Kaede Kayano. The Ikemen one is Yuuma Isogai. Baldy there is Taiga Okajima. The girl with short hair is Hinata Okano. The girl with glasses is Manami Okuda. The one with the barrette is Megu Kataoka. The pretty girl is Yukiko Kanzaki. The guy with the spiky hair is Masayoshi Kimura. The girl with orangey hair is Hinano Kurahashi. The dude that's drawing it Sousuke Sugaya. The one with the baseball is Tomohito Sugino. The boy that's reading is Koutarou Takebayashi. The guy with his hair down his eyes is Ryuunosuke Chiba. The group over there is Ryouma Terasaka, the leader with two hair colour shades, the dude with black hair is Taisei Yoshida, the dude with blond hair is Takuya Muramatsu, and the lone girl is Kirara Hazama. The girl with long blonde hair is Rio Nakamura. The girl with twin tails is Rinka Hayami. The chubby one is Sumire Hara. the girl with purple hair is Yuzuki Fuwa. The boy with darkish orangey hair is Hiroto Maehara, and the other boy with orangey hair is Kouki Mimura. The girl with long brown hair is Touka Yada."

"Wow, great nicknames." I said sarcastically. "You're telling me. Anyways, should we start our plan?" I nodded. "I'll be where Nagisa is." I walked over to where Nagisa was and sat down. "Hi! I'm Erina. You must be Nagisa, correct?" He nodded. "Yeah. Nice to meet you." We looked over at where Karma was, distracting Koro-sensei. "You think he's trying to do another assassination attempt?" I asked Nagisa, and he nodded. "That's very Karma-like for him to do, considering that he's very sly."

From where he was, I could see him give the signal, and I smirked. Carefully reaching in my pocket, I took out my detonator and hid it behind my back. I gave him the signal to retreat, and when he was far enough, I pressed the button.

An explosion of BBs shocked everyone as I quickly shoved it back in my pocket and feinted shock. When the smoke faded away, there was yellow goo on the ground, and Koro-sensei's front tentacles were gooey. Smirking, I stood up and clapped my hands. Everyone stared at me, shocked and scared.

"I'm shocked Koro-sensei." I said as I approached him. "How did you not know that it was me?" I picked up my destroyed necklace and held it in front of him. "I put Anti-Sensei BBs into the pendant. Luckily for me, Karma-kun helped me out with distracting you. I sat with Nagisa and detonated it when the time was right."

I was now right in front of him, and noticed that his tentacles had regenerated. "So, how did I do?" I asked, and his faced turned into a red circle. "Good job Erina! The way you planned everything out was perfect. You have the skills to assassinate me." I rubbed the back of my neck. "Really? I'm not that good."

"Nonsense!" Koro-sensei went to pat my head, but when he touched it, his tentacle melted.

"Fooled again." I brushed off the goo and smirked. "Really Koro-sensei? I thought you would know by now." Reaching in my hair, I took out a small piece of a knife. "Anyways, those are the only tricks I have, so I guess I'll just keep on training." Turning to everyone, looks of shock were still on their faces.

"What? Did Karma not do the same thing?" I asked, and said boy went up to me. "Sure did. By the way, you really are short." An irk mark appeared. "I'm not that short!"

He laughed. "Sure you are. You're the same height as Nagisa, and the perfect arm rest." He said as he put his arm on top of my head. I started twitching and soon enough, I tackled him to the ground. We started having a little fight before Koro-sensei stopped us. "No violence, unless it's killing me, alright?"

School was finally over. After our lessons, I walked home with Nagisa and Karma, for they lived the same way. Stopping at an apartment building, I waved goodbye before entering my place. It was pretty normal and barren, for I couldn't spend my well-earned money so easily. Changing into something else, I packed a few things before going to my workplace.

"Hey there Erina!"

"Isogai I didn't know you worked here."

"Yeah, this is actually the reason why I'm in the E class. Students aren't allowed to work, but I need to make money for my family." I nodded in understanding before getting to work. While working, I observed Isogai and learned something.

'He really is an ikemen, just like Karma said.' I thought as he charmed his customers. Shaking out of my trail of thought, I delivered a parfait to a table and took another's order.

"So, how come I never see you?" I asked. We had finished our shifts and gotten our monthly pay. "It must be the shifts. I used to work on Monday, Wednesday, Friday, and Sunday before switching to Tuesday, Thursday, and the weekends." I nodded my head. "I work on Tuesday, Thursday, and Saturday, so no wonder we didn't see each other." Looking out the window, I saw that it was getting dark. "We should go now." We said our goodbyes before leaving.

I arrived at home and took a shower before going to bed. Today was an exhausting day, and I needed my sleep.

"Good night, Kaa-san, Tou-san, and..." I trailed off, falling asleep.
