Trauma (Sero x Reader)

Chapter four

It's been about three days since the incident at the USJ facility. I haven't left my house. I didn't go to UA. They calling trying to get me to come in. I can't leave my bed. I'm scared. I feel like I'm suffocating. Why why why. I just want to find the truth of my past. Why did he show again. After all he's already done. That's all I could think about during this time. When will someone defeat that monster.

Who's here? It's Saturday. Why would anyone bother coming to my apartment. What if it's shigaraki. Shit. I activated my quirk and slowly walked to the door.
"W-w-who's there?" I asked slowly.
"Aizawa." Sad flatly behind the door. I slowly open it. To see Aizawa in bandages from the villain attack.
"W-what b-brings you?" I stuttered out.
"You need to come back to the school. Don't you want the training?" He asked.
"Y-y-yes, but.."
"But, what? Don't let something in the past hold you back. Plus you need to tell me how you already know him." Aizawa stated kind of coldly to me.
"It's a long story. Do I have to tell it." I whispered.
"Yes." He said.
"F-fine, sit down here. W-want something t-to drink? It'll be a long story." I say shyly.
"No, now start" Aizawa says while taking a seat down on the couch. I sit on the chair across from him. I breath in and begin.
"I was a senior, or fourth year in  America. Graduating in two weeks. I went to a hero school at the time. My heart for a while was set on being a side-kick so the lime light wouldn't be on me. It was just a regular day like every other one we had this year. I was finishing getting my stuff together with my class mate, Sarah. She and I just had small talk. When we heard screams. We followed those screams out to the court yard, where a portal had opened. Villains appeared. As this being a hero suit it was easy to begin combat with our quirks. I run in and grab my mask. I run back out. My head and stomach wasn't prepared to see what I had. Students were charging shigaraki. The Namus attacking teachers. Pro hero's began arriving. Students, teachers, and hero's one by one dying by the hand of shigaraki. They would just turn to dust and blow away in the wind. I screamed for Sarah to turn around and leave. My one and only friend at school. 'Sarah don't! He'll kill you too!!' It was too late she charged at shigaraki and he simple touched her. She was gone. Tears in my eyes. I thought there was nothing to do. At this time I thought I just had a healing/boosting quirk. That's why I only wanted to be a sidekick to help a hero. But inside me at that time was rage and anger. Hear a voice scream kill him, kill them all. I activated a quirk unfamiliar to me. I charge at shigaraki he goes to touch my face only to touch my mask. It disintegrated just like my friend. He goes again to touch me. I used my quirk and pushed him back. Anger bubbling inside me. I charge forward again. Ignoring the pleas of the hero's and teachers to turn back. He grabs my arm I prepared myself to start disappearing like my friend. Nothing, nothing happened. 'What! Why aren't you dead?!' Shigaraki screamed at me. 'I'll be taking this one then' he grabs me yanking me to the portal with him. 'LET GO OF ME! You sick son of b*tch' I screamed to let go. Nothing I was dragged into the portal. Only to see a plain room on the other side. I get smacked on the head with something hard. After a while of being unconscious I wake up in a chair. 'W-w-where am I?' I asked. No one answered. My head was pounding. Finally I hear a sound on the other side of the room. A door opens and in comes shigaraki. 'Who are you?' He demanded. 'What do you mean? I'm just a high school student' he wasn't amused by my answer. 'How can you not die from my touch?' He's walking closer to me. That's when I see he had something with him. 'I don't know, I don't even know who my parents are!' I screamed at him. 'What do you mean?' He sets the item down. 'I'm adopted!' I'm squirming under my restraints, but to no avail they wouldn't come lose. He puts some wires on me, flips with switch and electrocutes me. This went on for 3 months. Everyday asking questions and electrocutes me. I still didn't have the answers he was looking for. Finally he had enough and shocked me with as much as the battery would allow him. When I was close to death they ditched me in an alley. After lying there for what felt like an eternity. Someone found me. I wanted revenge but I also wanted to know who I was. My parents still wouldn't answer questions about my past. Why didn't I have memories from when I was little? After that I decided to go find the answers myself." I sniffled a little after finishing telling him about my encounter with shigaraki and how he was searching for why I wouldn't die. I looked at Aizawa who was looking intensely at me.
"Is that all I need to know?" He asked calmly.
It wasn't everything. No. I just didn't want to talk about them also trying to make me a villain. He tried really hard to bring me on their side, but I wouldn't. So he tried to kill me instead.
"Y-y-yes" I whispered.
"Thank you for your honestly. I feel like you'll make friend here. The kids in my class are good kids and they are all really friendly. Except for bakugou he'll probably yell at you. I'm sorry you saw your friend die. But find someone here you like and trust. Open up to them. Carrying this around will only make you suffer" Aizawa commented. Someone I trust huh? I guess I'll actually have to make some friends. Easier said then done.
"T-t-thank you, and I'll try."
"Oh, and one last thing. Come to school on Monday to help the students train."
"Yes, s-s-sir" with that Aizawa had left and I went back to my bed. Thinking about everything. I hate shigaraki. I will kill him. I'll kill him and all of his friends. Tomorrow I'm going to try and dig up more of my past too. If I was one of the only people shigaraki can't kill. What else about me is different.
