My Hero Academy x Assassination Classroom REDOING

Memories Back

Izuku POV
I was dreaming again, kids with rubber knives trying to aim at a black colored hair man, a yellow octopus with clothes smiling and observing the kids. "Good job everyone." The man with black hair said, his expression was serious but he was happy, why?
I saw that these kids were smiling as if they just won the lottery, they were excited but....why? What was so fun of holding a weapon and trying to strike someone but you fail to even touch him? Why were these kids happy when they lost? I don't understand although I am a human and part of my human self died years ago, why can't I also feel what they feel?
My heart started pounding like crazy, "Never feel emotions. You are created to be emotionless like a robot. You are just a killing machine that should not feel emotions." A male voice said. The voice sounded exactly like Reaper, he was still haunting me in my dreams and my mind.
I woke up to feel my chest tightened every second as if it was shrinking, my heart was burning as if hell has broke loose. A green glowing circle appeared on the floor around me. 'Why is this so familiar?' I was suffocating as if all the oxygen in me has left and abandoned me. I struggled for air and the circle disappeared slowly and I was catching my breath.
I layed on the ground for a while until I heard footsteps going everywhere around the dorm. I sometimes hated having good hearing because I could hear every little thing and it made me want to go crazier than what I already am. Someone barged into my room and it pissed me off, I didn't care who it was I was going to give them a piece of my mind.
Mr. Aizawa looked at me confused while I was ready to charge at him when he said, "You did it again, come with me." Huh? What did he mean I did it again? I followed him since recovering from my sleepless night and countless dreams that I never had in the past.
I was taken outside of the dorm and saw kids with the same uniform on as if they were in gym class, they must be from a school around here. "You cocky bastard, why did you bring us here!" Someone yelled at me. Who is this porcupine looking head guy and who is he yelling at? I stayed there emotionless looking and observing each of them.
"Answer me!" He said. I then said with a smirk on my face, "Sorry but I'm quite confused here. You're yelling at a cocky bastard but I don't see anyone with that description here around us unless you are talking about yourself." He clenched his fist and aimed it at my but I caught his fist and kicked his stomach. He dropped to the floor, I guess I still can't control how much force I use.
"Mr.Aizawa why am I here?" I asked annoyed at how these kids are glaring at me. "You don't remem-" he was cut off by a woman "Izuku!" she rushed towards me a hugged me. I flinched at the sudden touch of a woman and couldn't react on time.
I didn't know what to do in this situation so my only reaction was to back away a little, she had beautiful blonde hair and attractive body. She was like a goddess from heaven but who is she? "Hey beautiful lady, I am deeply sorry for not remembering such a pretty face like yours but may I ask.....who are you?"
She stumbled back a few steps away and she seemed shocked and confused almost hurt. I was getting impatient so I asked Mr.Aizawa, "Who are these people?" He sighed and didn't answer my questions. "Where is your other teacher and the octopus?" He asked the other kids.
They were about to answer when a gust of wind was felt and almost knocked the trees away. "You called me." A yellow octopus appeared before us with a big smile across his face. Wasn't he in my dream just a few minutes ago? "Please come in, I will explain what happened during the time you were gone." My teacher said with a tired expression.
My class was looking through the window and Mr.Aizawa order them to go to class. I was ordered to stay behind with the new kids and their teachers. After everyone was settled inside the living room a heavy atmosphere was sensed by the kids and the blonde woman.
"When Midoriya transported you back well he went unconcious for a few days and woke up with no memories of anyone including himself." Mr.Aizawa explained and thankfully he didn't say that I remember my 10 years in Room X. Do they even now about that? I don't think my past self would open his mouth and blurt out the only memories of my training as a villain.
The blonde woman looked even more devastated while I just sat in the couch emotionless. Well, what was I suppose to say? Sorry or something? The octopus was summarizing a few things about there world and about his class and the reason for his students to kill him. Oh, I think my dream was not only a dream but real, these kids are being trained to kill this Korosensei.
He had a strong smell of chemicals in his body and a scent of...human. So he is also an experiment, just like me and Principal Nezu. "How did it feel?" I blurted out in a whisper but everyone heard me. "Nothing" I said and they continued their conversation.
I heard a women's voice and it sounded like the blonde woman who hugged me earlier.

"So what do you suggest."

"I'll kill him for you and your students, and you all can take the reward. I only need you to convince those kids to move out of my way. I know you like those kids as if they are your own and I know you wouldn't want them to feel hurt. Would you like to be my partner in crime for this plan, Ms.Jelavic?"

"It's will be an honor to work with you."

Oh, so she is my partner in crime the famous assassin in her world. She is quite something to be able to talk to her students as if she isn't betraying them. I guess my past self wasn't so stupid after all, he managed to pick Ms.Jelavic as an ally to kill Korosensei. Very well my job begins now I guess, I would have been bored if I only had to learn about heroes. I now have a to learn both to achieve my goal. After killing Korosensei I can leave this place and probably by that time I'll be able to teleport into a different world so I won't be found.
This will sure be an interesting year, Class 3E you better watch out because I'm coming for your teacher.
