Third P.O.V
"Are you in position Oni-chan? I can already see our target who is surrounded by guards fully armed with P90 submachine guns." The younger sibling told her older brother though a earpiece while watching their target though a scope. "So the asshole brought a few friends huh? Welp this is going to be a hell lot more fun." The older sibling said to himself and pulled out a custom made machete "Oni-chan want me to fire at them while you slaughter them all?" The female sibling asked but heard a chuckle. "Sure but try not to hit me in the progress." He said which made the small girl angry. "WHAT DO YOU MEAN? IV'E NEV-" She realised he wants to kill them all on his own, so she instantly looked back at her scope and waited for her brother to attack
Before the to began their attack
"Something doesn't feel right, where the fuck are the people we'll suppose to meeting up with?" The target said to his guards as he feels like this might be a trap. "Hey can I ask you a question sir?" the male assassin asked his target while holding his weapon behind his back. "Listen you little brat, I'm not giving any money so get lost." The target replied and before he grab his gun, the assassin slit his throw by swinging his machete at his neck. "BOSS!" "Why you little fuck your going to pa-" A gunshot was heard and before the guard could finish his sentence,as bullet went straight though is head killing him instantly. "Who the fuck are you working with kid?" Another guard asked the male assassin who gave a cheerful smile but behind it it was a sadistic smile.
"Well, because your going to die I might as well tell you why I killed your boss." This started to frighten the guards and which one started to flee from the scene but another gunshot was heard which killed the fleeing guard. "Have you ever heard about the Silver Twin Assassin called Akoni?" The assassin name himself and bowed with a grin which all the guards now know who this kid is and they already know how deadly that this assassin can be. "Wait this has to be a dream, it has to be... oh god I don't want to die!" One of the guards started having a mental break down only to have his life ended by another bullet. "I only killed two of you and my sister killed three of you so it's only fair that you let me kill you as quickly as possible. " The assassin started charging at them slaughtering all of them
Akoni P.O.V
"You should be honoured that you was killed by me, after all I AM the Silver Demon ehehe." I said to the dead corpses and began laughing but I got interrupted as I saw the moon exploded which made me whistle. "Oni-chan did you just saw the moon exploded?" My sister yelled as she dived at me. "I sure did and I guess somebody fucked up big time and now we got a permanently crescent moon." I told my sister. "You sound so calm Akoni-chan, the moon just exploded and you look like you don't even care." My sister tried to lecture me which I just sighed. "Akane-san how many times do I have to tell you not to call me chan and second it's the governments fault for whatever they were experimenting on the moon so don't worry about it it's not like the Earth is next.
One Month Later at a Government building
We'll waiting for someone to tells us why are we here or are we finally caught for all the assassinations we have committed but then the door opened and three people with suits came in. "I guess you know about the recent event that occurred a month ago." She said and I guess I was wrong. "I thought for a second we was going to pay for our crimes but please continue." I said polity as possible. "Anyway the person that destroyed the moon plans on doing it again but this time it be our planet. Your job is to assassinate him by any means as possible but however to make things clear your not allowed to harm the students." She told me and I got confused when she said students which means is he some sort of a teacher? "So you want us to pretend that we'll students?" I asked to make things more clear
"That's correct, you be joining the students on killing the target but just to be clear, your not allowed to discuss anything about the target to the general public, the consequences of doing this will result of a full blown memory wipe... do I make myself clear?" She scared me but at the same time kinda scary. "Don't worry about it, I promise that everything I learned won't go to the general public. Plus I'm kinda getting excited to meet him and are you sure these knifes can kill him if so it's kind offending my talents." I said while throw a rubber knife in the air and catching it.
"Well your target can move the speed of Mach 20 and normal bullets won't worry as we've already have tried that otherwise we would be having this meeting." She told me and her eyes tells me she isn't joking. "Okay sure we'll help you out, after all we haven't kill anyone who can break the sound barrier right sis?" I accepted the contracted"Yeah and something tells me this might take while." Akane told me and usually she's right. "If you's two succeed, you be given ten billion yen for all assassins that took part." She told us which made my eyes widen which means they are very serious about this
The next day
Nagisa P.O.V
("I overheard Karasuma-sensei that we'll getting two students who are profession assassins so I wonder wha-") "Nagisa, your not paying attention... if there something on your mind?" Kayano whispered but she sounded concerned "Well apparently, we'll getting two new students and I accidentally overhea-" Before I could finish I felt a gush of wind and there's Korosensei stand right in front of us. "May I ask what are you's two whispering about while I'm teaching?" Korosensei asked and I might as well tell him." I'm sorry Korosensei but I overheard that we'll getting two transfer students to help with the assassination." I replied and he just blinked at me and laughed. "Thank you Nagisa-kun for reminding me, I almost forgot to tell you all. You'll all be getting two more students to help you to assassinate me but it's not like it would matter anyway, no matter how good they are." Korosensei told us but what did he mean by how good they are? "We'll be getting two more students, so who are they?" Karma asked but I bet he's thinking the same thing as I am. "Well to be honest, these student are apparently are twins who's names are Akoni Akatsuki and Akane Akatsuki but I was also informed they are trained assassins, but it's not like it matters anyway." Korosensei said being cocky. "Awesome! Your saying we got two girls joining us and THEY are twins? I really hope I'll get along with them." Maehara yelled but I don't think he heard that they are trained to kill
"STOP BEING A WOMANISER MAHEHARA-KUN! YOU BETTER NOT SCARE THE NEW STUDENTS OR i'LL BREAK YOUR ARM LIKE THE LAST TIME!" Okano yelled which I don't want to know what he did last time. "Well to be honest Maehara-kun it looks liked your misunderstanding with their names." Korosensei replied which means their brother and sister. "Wait what do you mean Korosensei?" Maehara asked still clueless. "He means that the twins aren't both girls as one of them a boy which is most likely Akoni as that name is used for both genders and I doubt he'd let you flirt with her." Kataoka stated and I think I can get confused with their names as they sound similar.
"Whoa I thought that they were joking but you really are a octopus... so I'm guessing your Korosensei?" A girl with white hair as snow said to Korosensei with a cheerful smiling but something about her... seemed off. "Well then, I'm guessing your-" My eyes widened after what I just witness. She just cut of Korosensei's arm with excellent speed. "Heh I though they were just over exaggerating but it looks like you really can break the sound barrier." She replied cheerfully. "Fufufu, As I was saying you must be Akane Akatsuki so now where is your brother may I ask?" Korosensei asked her while being cocky next minute something was thrown though the window and it looked like a grenade and when I looked at the new assassin she was covering her eyes which means it's a flashbang but Korosensei caught it and threw it back outside and closed the window. "Better luck next time Akane-san so now tell me where's your-" We all heard a crack like glass and whenI looked at the window there was a bullet designed to kill Korosensei stuck in the window but it's shape was totally different than ours as it looked like a real bullet.
"Let me guess what you was planning on doing Akane-san, you'll enter the classroom first while your brother watches you to attack me to see my abilities which he then uses a flashbang to blind me so he could shoot me." Korosensei stated but we still haven't met her brother which means the attack isn't over. "Your actually half correct Korosensei but who said our attack failed?" She replied to Korosensei which the door opened violently and someone charged into the classroom and started attacking Korosensei but failed as Korosensei grabbed his wrist but something weird happened as the male assassin broke free. ("What's... going on here? Korosensei stopped him, so how did he break free from Korosensei?") I tried to think of what he could of did but couldn't think of anything.
Third P.O.V
"Good morning Korosensei, I can't believe you manage to stop our attack but don't worry there WILL be more attempts on your life so you better repent while you still can." The male assassin told Korosensei in a sadistic tone which gave the class shivers but most of all how he escaped Korosensei. "So your Akoni Akatsuki, don't you think it's rude to attack your teacher without introducing yourself." Korosensei said to him being cocky but this only made the assassin laugh. "How amusing, your the one who destroyed the moon and here you are telling me I had to introduce myself to you in order to kill you." He continued.
"Korosensei my brother is right, why should we introduce ourselves when your the one who's planning to destroy the planet" Akane stated standing next to her brother. "Alright enough introductions, why don't you take your seats at the back of the class?" Korosensei told them and without reply they just walked to theirs and before they sat down they pulled out guns and began firing but Korosensei dodged them. "Fufufufu nice try you's two but the class has already tried that already." Korosensei taughted them which made them growl.
Later
Alright children as you know I be going to another country so I be back soon." Without Korosensei flew off which Akoni got up and slowly walked to the front of the class. "He sure loves to go to other counties doesn't he?" Sugino asked. "Well I have to agree with you on that one." Nagisa replied but not knowing Akoni is right behind him. "Pathetic isn't it?" Akoni asked which scared Nagisa and Kayano."Akoni-kun you shouldn't care people like that!" Nagisa replied back to Akoni he didn't care. "Listen moments like these are probably the only times we can discuss on how we'll going to kill him isn't that right sis?" Akoni told them but also asked his sister for confirmation. "My brother is right but Akoni, you do know you shouldn't just sneak up to people and frighten them." Akoni just sighed over her answer. "Hey I'm meaning to ask, how did you escape from Korosensei's grasp? He was hold your wrist to prevent you from attacking and yet you manage to escape and damage him at the same time." Nagisa asked and Akoni opened one of his eyes and looked at Nagisa "I'm going to refer you as Bluebells for now on but to answer your question, I have the material that harms him on my gloves in case something like this were to happen. Very clever if you ask me." Akoni replied
"Bluebells huh? I think that fits you fine doesn't it Nagisa-kun?" Karma asked his friend. "No it doesn't and Akoni-kun you-" Nagisa couldn't finish as he saw Akoni throwing and catching a bullet. "Bluebells let me tell you something so idiotic, that it could off killed you." Akoni was now right in front of Nagisa's face. "You tried to kill Korosensei by hiding a grenade by your neck which exploded... You do know that it could of taken your whole head off if he didn't save you." Akoni scolded Nagisa but the way it sounded it seemed like he hated the idea.
"Wait are you saying that it could of killed Nagisa?" Kayano asked being very concerned about Nagisa. "Well if the explosive didn't kill him, he would of gotten a damaged jaw, possibly worse. Hey don't you scare do that shit around me as only cowards do that." Akoni replied back to Kayano but also told Nagisa not to do it again and with that he walked off with his arms back of his head.
That's it for now you guys and i have updated both chapter fixing and rewriting as the dialog for both OCs didn't fit them especially Akoni as he was kind two aggressive in chapter 1 so I rewrote the whole thing and it actually made the whole story much more interesting according to my friend Autistic-Grizzly who also makes amazing fanfics so you should also check him out.. While chapter one is shorter than the original as I realised Akoni was being a bit of a bastard to them and I have future ideas and who I am pairing with in the future as it helped me develop his personality and his backstory but anyway I really hoped you guys enjoyed it
