My Hero Academy x Assassination Classroom REDOING

Nurse Room

Mr. Aizawa POV
Korosensei told us that Midoriya would be participating in the festival, I disapproved but he was already in the arena. He called himself the Mystery Shadow, I chuckled this child couldn't hold his erge to have a fight. I let Midnight know that Mystery Shadow was allowed to fight Todoroki and if things got out of hand to stop them. At first Midoriya only avoided Todoroki's quirk but they seemed to have had a heated discussion and I was able to see his fire quirk for the first time. 'So this goal was to make his use his left side.' I said to myself.
After a while there fight seemed to be getting serious when Midoriya was holding his chest for a moment. Both were ready to launch their last blow, "Midnight stop them!" I yelled over the earpiece.
Cementos created a wall but somehow Midoriya went all the way to the wall. Todoroki was announced as the winner and ready for the next match with Bakugo. I left the room to go check on Midoriya and I saw Korosensei taking him in a flash.
I went inside the building to check on Class 3E but nobody was there, I went back to the arena to see if Class 1A saw them. "Korosensei took them quickly but we don't know where." Uraraka said.
I went to the dorms and went to the guys floor and to Midoriya's room, I managed to see a bright green light coming out of the room. I ran inside and saw Midoriya on the floor unconscious, what happened? I saw a journal, a circular container and a wooden box on the floor next to him. I carried him to Recovery Girl, "oh dear what happened?" She asked.
"I dont know if it was because of the fight he participated or because of Class 3E." She checked him and said, "He is okay but his leg is injured, he'll probably wake up after a while." I gave her the journal that was in his room, I couldn't read much but a line of the first page. "I think that he wrote this while with us, give it to him when he wakes up. I went to find Class 3E and not even the teacher's were here anymore. Midoriya must have sent them back to their dimension."
I went back to the observation room and Bakugo was fighting with Iida after that match was over he won Tokoyami. The final match was Todoroki and Bakugo, I wonder how this will turn out. Bakugo seemed angry that Todoroki isn't using his fire quirk, and Todoroki seems to be confused at what to do. At the end Todoroki was defeated for being in his thoughts and not active on battle.
Tokoyami, Todoroki and Bakugo won the top 3 place in the tournament, after Bakugo threw his tantrum I left quickly to check on Midoriya.
"Mr.Aizawa, where is Midoriya? I need to speak with him." Todoroki asked. I didn't even notice he was behind me, I must have been thinking too much.
"He isn't available right now, you can talk to him tomorrow." I said and Bakugo had to appear. I have to get put of here, he is too pushy for me to handle. "Where is that deku!"
"He isn't available, go home and visit your parents." They left and I thought that it was too easy, I somehow felt uneasy that they didn't ask again. I let it go and went to Recovery Girl, when I grabbed the doorknob I heard Todoroki's voice, "Oh so he was here. Excuse me sir." Midoriya was still unconscious, "He still isn't awake, he seemed to be in a shock." Recovery girl said.
"Was it because of my quirk?" Todoroki asked and I shook my head, "No, after he ran off after you won he had a sort of accident."
Midoriya groaned and his eyes started opening, "Where am I?" He asked sitting up and looking around. "You are in the infirmary, Midoriya." Recovery Girl said and he seemed to have flinched when he saw us. Something isn't right about him, his gaze seems like last time he was unconscious. "Are you alright?" He had a poker face that I couldn't read. "Who are you?" He growled his voice changed. "Stay back." I told Todoroki. "Go and get Midnight, Recovery Girl." I told the nurse, she seemed to have noticed the situation. "Midoriya?"
Midoriya frowned, "Sorry I am not Midoriya, I am Subject 137." My eyes widened, how did this happen again?

Todoroki POV
Midoriya's gaze seemed to have changed, he seemed like he was confused and his guard was up. "Midoriya?" I wanted to make sure he was okay. "Sorry I am not Midoriya, I am Subject 137." Mr.Aizawa seemed shocked for a minute and in a sharp tone he told me to stay back. What happened to him?
"You are Erasurehead, right?" He asked with a threatening smile. Mr.Aizawa nodded and Midoriya quickly jumped at Mr.Aizawa, "Don't even try to do anything, Erasurehead!" Midoriya seemed like another person. Mr.Aizawa managed to dodge his attack and Midoriya made a hole on the wall with a punch. "Mr.Aizawa what is going on?" I asked but he didn't respond, he kept me behind him as if Midoriya was a threat.
Mr.Aizawa used his scarf to trap him but he managed to slip away and pinned Mr.Aizawa on the floor. I grabbed Midoriya, "Let me go! I have orders to kill any hero in my way! Let me go!" He yelled. What is he talking about, is he delusional?
"Midoriya qui-"
"I'm not Midoriya, I am Subject 137! I'll kill everyone in my way so let me go, you stupid kid!"
Midoriya suddenly slipped and disappeared on the floor like a ghost. "What the hell!" I felt a presence behind me, "Watch out!" Mr.Aizawa yelled and I used my ice quirk which made Midoriya lose balance and Mr.Aizawa caught him, "Midoriya you are no longer in Room X, we are your friends!" Mr.Aizawa yelled but Midoriya wasn't listening. Room X? What the hell is that?
"You think you can trick me with that lie? I'll kill you Erasurehead, I will kill you and every hero in this world!" Midnight appeared and wasn't shocked that Midoriya was like this.
"More heroes! That's so great, I'll kill you all together!" Midnight used her sleeping gas, I covered our nose and mouth. Midoriya seemed to not be affected and Recovery Girl injected him with something.
He fell on his knees and dropped, "Restrain him before the drug doze off!" She said. "Todoroki please leave!" They said but I stayed still in shock about what we have seen.
The teachers didn't seem to have noticed me. Midoriya woke up again, he was growling at the teachers. "Midor-Subject 137, we know about those guys that kept you in the dark room. You are safe here with us, we will do you no harm. Do you understand?" Mr.Aizawa said and Midoriya nodded.
"If you try anything we will have to tie you again." The teacher untied him and Midoriya raised his hand to attack but Midnight stopped him and shook her head.
Recovery Girl handed him a box and Aizawa spoke, "This was in your room."

Izuku POV
I opened the box and saw a journal, a metal round container inside. "Mr.Aizawa." a kid with red and white hair talked. Erasurehead seemed to have flinched and turned to look at him, I wanted to attack him since he was off guard but Midnight was watching me. "Didn't I tell you to leave?" He asked angry. "What is wrong with Midoriya?" He asked. Why does this kid keep calling me Midoriya?
I tried to open the round container but it didnt have any button, "How you open this?" I asked the heroes and they shrugged. "We didn't know you had these things with you." He said. Wow, so if would have brought a gun in his box they wouldn't even know.
I turned the round object over and saw a hashtag, I titled my head, 'hashtag means number.' My tattoo on my neck has a number, I raised the container to my neck and it said, "Subject 137 verified" it opened and  a voice was heard when I pressed a button. I saw my green pills inside the container.
"Hey Subject 137 it's me Doctor Shaun, you probably won't remember me since you didn't really like me but if you hear this recording it means I'm surely dead by Reaper or Spades, haha. But anyways I stole a few pills that were used to suppress your quirk from the lab because I really pitied you when I saw you being tortured in that room. I kinda left clues for the heroes to find us so you could be rescued and the organization could be destroyed. I....I know it won't be easy to forget the 10 years of torture that you been through but I want you to live. Subject 137 use the quirks that have been given to you to continue a good life, trust and learn to become a human again. Bye."
So it is true that I am no longer in Room X. I looked at the heroes who had their eyes fixed on me. I opened the journal and the first thing I read was.

If you have green hair and green eyes and probably wanted to kill a hero once you woke up, this is your journal....

To be continued......
