I woke up one morning. It was my first day at Kunugigaoka Junior High School. I looked at the clock 12pm. "Fuck!" I yelled and quickly put on my uniform. I grabbed my knife and hid it in my pocket. I ran to the front gate of my school. Even though I am qualified for A class. I'm in E class to kill that alien the destroyed about 70% of the moon and planned to do it to Earth. I saw a guy with orange hair and purple colored eyes leaning against the gate, reading a book. He noticed me. "I've been waiting for hours. No wonder you're in E class." He said and a tick mark appeared on my forehead. "Nice to meet you too." I growled and he smirked. He seemed to be amused by my annoyed expression. "I'm Asano Gakushu, A class. And you are?" He said and started walking. "None of your business." I said and walked next to him. He continued with the tour. "This is the main building. E-class is not allowed in here unless it's an assembly or school event." He said and I rolled my eyes as we walked around the main building. There were some guys staring at me and drooling over me. I sighed. "Could you just tell me where E-class is so I can leave?" I asked and Asano point to a mountain. "Up there." He said with a smile. I groaned and opened the window. "What the hell are you doing?!" Asano yelled. "I'm going to class." I said and opened out the window then landed safely on my feet. I sprinted to the direction of E-class.

Karasuma's POV: "She's late." I muttered and looked at my watch. "Take a break for now." I ordered and the kid fell on their butts. "Karasuma-sensei, didn't you say there was a new student coming?" Kayano asked. "Yeah, where is she?" Isogai asked. "Tell us about her." Nakamura said. I sighed. "I found her and adopted her when she was six and all I can say is that she's....interesting." I said and the class caught a view of a running behind him. "Is that her?" Karma asked. "Karasuma!" [Y/n] said sweetly while jogging towards me. I nodded. She then starting running at me in full speed and landed a flying kick to my back. "Why the hell did you not wake me up?!" She yelled and class was staring at her in shock. I stood up and winced in pain. "I had a choice either wake you up and get stabbed or leave." I said and she sighed.

Your POV: I looked at the octopus alien. He seemed a little scared. I smiled kindly. "You must me Koro-sensei. I'm [Y/n], nice to meet you." I said and he seemed to calm down. I held out my hand and he shook it when suddenly his tentacle exploded. I kicked him and exploded 2 more of his tentacles then I took out my gun and shot 3 more of his tentacles with Anti-sensei BB's. Koro-sensei was freaked and used his Mach 20 to hid behind a tree. I clicked my tongue and glared at him. "Seems like you can still use your Mach 20 with two tentacle." I said and reloaded then took the taped Anti-sensei knife pieces off of my hands and shoe. I turned to the class who was looking at me in shock. "This is [Y/n] Karasuma, daughter of a high class assassin and my adopted daughter." Karasuma said. "I didn't want them to know that." I said and glared at him. "I'll be in this class only to kill that thing. I don't want or need friends. I treat all my missions the same. Get in, kill the target, get out." I said and started walking away. "Where are you going?" Karasuma asked. "I knew the target and the area. There's no need to be here." I said and walked all the way back the your apartment. Karasuma sighed again. "Well, she was a total bitch." Karma said and most of the class agreed.

~next day~

i actually woke up on time and changed into my uniform. i made sure i had my knife and walked to school. when i finally made it to the main campus, i saw two guys making fun of that blue hair kid from my class. i walked over to them and gave to two boys in intense glare. "would you rather go to e-class or hell?" i growled and they backed away. "because if it's hell, i can surely take you there." i continued and pulled out my knife. they screamed and ran away. "aw man, i really wanted to gut them like a fish." i said. 'i have to keep cool. my bloodlust will not take over. well at least not here.' i thought to myself. i put the knife away and saw asano looking at me then smirked. i flipped him off then turn the guy. "don't let people walk all over you next time." i said and started walking to class e with him following a behind. "u-um...thank you...for earlier. i nagisa shiota." he said with a smile. "there's no need. i just hate when people treat other's like trash for no reason. i still have no interest to be your friends." i said. we made it to the class and i took my seat next to a red-head. ~ "now, allow me to introduce your brand-new temporary foreign-language teacher." karasuma said. i looked up and saw irina hugged up against koro-sensei. "looks like jelabitch is back." i muttered to myself. little to my knowledge that karma heard irina's nickname and chuckled. "the school intends to give you authentic experience in foreign languages. i trust there are no complaints about her taking over half of your english lessons?" karasuma said. "if we must..." koro-sensei said and i smirked. 'wait until they learn her true colors.' i thought to myself and leaned back in my chair.

After class, I stayed with Karasuma and Irina. "It's good to see you again, Jelabitch." I said and she glared then hugged me. "[Y/n]-chan, I've missed you!" She said and I groan. "Get off!" I said and pushed her. She pouted. "Aw, don't be so mean. How do you plan on making friend or even a boyfriend?" She said and winked. I rolled my eyes. "I don't need neither." I said and left to go to the field. I laid in the shade under a tree while I watched Irina flirt with Koro-sensei then the yellow octopus used his Mach 20 speed to fly into the air. I stood up once I heard the bell ring. 'I guess I'll be in this class to protect her.' I thought to myself and laughed a bit. I walked over and saw Irina kissing Nagisa then she explained her plan. I raised a brow and walked over to the three men. God, they stink. "Jelabitch, this plan will not work. Trust me." I said and crossed my arms. She smirked. "You think so?" She said. "Yeah, if you don't believe me, go ahead with your plan. I won't bother you." I said. She patted you head. "[Y/n], sweetheart, this is an adult thing. You wouldn't understand." She said. "I've been training as an assassin since I was 3. I even on missions with Karasuma. So I think I knew what I'm talking about." I said and hit her hand and started walking inside. "But people don't listen to kids." I said. Once in her class, study hall began. I could tell that everyone hated her. More than they hate me. "C'mon, Bitch-sensei, teach us already!" The boy, I believe his name is Maehara, said. "Yes, Bitch-sensei." Nakamura said. "Quit your 'bitch'ing!" Irina said. I smiled a bit as she started lecturing them on how V and B were different. After she left, everyone was complaining abut Irina. I was listening to music until Nagisa and a girl with green hair. She smiled at me and I took off my headphones. "Hello, I'm Kaede Kayano." She said and I nodded. "We wanted to know how do you know, Bitch-sensei?" Kayano asked and I sighed. "Her and I had the same teacher teaching us to be an assassin and foreign-languages." I gave a simple answer. "Then could you teach us English?" Nagisa asked. I narrowed my eyes while Kayano gave the puppy dog eyes. I sighed again and stood up. "Fine, if it'll get you off my back." I said an walked over to the chalkboard. I wrote a few sentences on the board in English and helped them with pronunciation and spelling. They continued to call me [Y/n]-sensei. It had a nice ring to it. Without realizing it, I began to smile a bit. I heard a gasp and my smiled faded into a frown. "S-she smiled." Nakamura said, dramatically. "What's that suppose to mean?" I asked. "Don't blame us, we thought your face was a permeant frown." Karma said and everyone else laughed. 'A monster like you could never make friends.' A voice rung in my mind. "I know." I muttered and looked down at my hands. I could have sworn they were stained with blood. I sighed and focused on my assignment.

My class was on the field practicing shooting when I saw Irina go in the shed with Koro-sensei. I shook my head and smiled. I walked over to my class and Karasuma glared at me. "You have to start arriving to class on time." He said and I waved it off. "Yeah, Yeah. Karasuma, you know as well as I do that her plan will not work, right?" I asked while raising a brow. "What are you getting at?" He asked. "Thanks to Nagisa-kun's intel, I know Koro-sensei's has the sent of a blood-hound. Those men in there stink with manly B.O. He will surely smell the men as soon as he steps in. And while Jelabitch was talking to those men, I snuck a peck at their weapons. They're using real guns, M61, M134, M249 to be exact, with real bullets, so this plan has a 5% chance of succeeding." I explained. "Wow, [Y/n]-chan, you super smart!" Kayano said. "To be a good assassin, you must narrow all possibilities of failing down and always have a back-up plan." I said and started to heard gun-shots. "Let's go see if she killed him or not." I said and started walking to the shed. Then I heard a scream and slithery noises. "On second thought, let wait until they come out." I said with a deadpan look on my face. "Let's go." Maehara said and started running to the shed. I followed behind. When we reached the shed, we saw Koro-sensei walking out with blush on his face. "I wish I could have enjoyed myself a little longer, but I'm really looking forward to our classes together." Koro-sensei said. "W-What happened in there?" Nagisa asked and Irina came out in an old fashion gym and explained what he did then fainted. "I...don't think I'm going to sleep tonight." I muttered.

Back in study hall with Irina. She was pissed. Some of my classmate would turn too me and say [Y/n]-sensei, wanting me to go and teach. "Dammit! Why doesn't this backwoods school have WiFi?!" She yelled and I noticed Karma sitting there with a small smile. "You're trying awfully hard, Bitch-sensei. Your pride must be in tatters after that. I mean, you say it's grown up business, but [Y/n] knocked off 6 of his tentacles in 5 minutes." Karma tensed and laughed a bit. Irina glared at him. "Sensei..." Isogai said. "What?" She said. "If you're not going to teach us anything, could you swap with Koro-sensei? Or at least [Y/n]-san? We've got entrance exams this year." Isogai said. Irina laughed. "Ha! You want vicious creature to teach you? You think your exams compare at all to a planetary crisis? Must be nice being a clueless kid. Besides, I understand you E-class students are the school's loser misfists. There can't be any point to studying now." She said and I glared. "I know, how abou this? If my attempt succeeds, I'll give you 5 million yen to share! That's far more han you'd gain from any pointless schoolwork! So shut up and do as I.." She said interrupted by my seat sliding loudly against the floor. I walked over to Irina and I slapped her across the face. Everyone was shocked. Irina was about to tell me off but noticed my intense glare, saying 'If you talk, I'll kill you.' "Who the hell do you think you are talking to them that way? Just because they're in class E doesn't make them any different. You need to check your social status in here because everyone hates you." I growled and she looked at the class. Everyone was giving her the same glare. "Now get out." I growled again and walked back to my seat. Everyone started yelling at her. My eye widened when I realized what I said. 'I'm getting too attached.' I thought to myself.

It was a free period. I sat near Kayano while she asked me random questions while I gave simple answer. Like yes, no, I don't know/care. Suddenly the door slid open and Irina came in. She wrote 'You are incredible in bed' on the board. I went back to my seat. "You are incredible in bed. Repeat." She said in English. I didn't say it because I was disgusted. "Y-You are incredible in bed." The class said. "When I assassinated a a certain VIP in America, I first turned on the charm to get close to his bodyguard. Those are the words he said to me. They mean: You're great in the sack." She said and some student blushed. "It's often said that the fastest way to learn another language is to get yourself a lover who speaks it. You want to know what they're feeling, so you try your hardest to understand what they say. When necessary in the course of my work...I have used that method to learn more than a few new languages. [Y/n] has as well." Irina said and everyone looked at me. "It was only once and I didn't enjoy it. I only had to sweet-talk the guy to tell me where his father secret room was. Not what you have to do." I said and crossed my arms. "Therefore, my lessons will teach you how to sweet-talk foreigners. The basics of chummy chats straight from a pro assassin: Master them and they'll come in handy with real live foreigner. Let that octopus teach you what you need for your exams. The only thing I can teach you is practical conversation skills. And if you still don't think of me as a teacher, I'll give up on my assassination and leave. Th-That ought to fly with you all. And...I'm sorry about all that stuff." She said with a faint blush on her face. It was silent for a moment then everyone started laughing. "Why are you so nervous? You were just threatening to kill us!" Karma said. I began laughing too and everyone quieted down at the unfamiliar laugh then stared at me with awe. I sighed and wiped a small tears from my eyes. "What? It was funny." I said and everyone started to freak. "She laugh too?!" "I think the world is ending today!" "[Y/n]-chan's so cute!" I felt someone hug me. It was Kayano. "You look so cute when you laugh! You should laugh often." She rambled rubbing our cheeks together. "Don't make such a big deal about it!" I said and tried to pushed her away. It was no use. 'A monster doesn't deserve friend. They're going to die. Someone will come after them. Or the might die by your hands.' The voice come again and I saw bloody hands again. I blinked and it was gone.
