Aizawa x Child!reader (Chainsaw man)

Recovering Memories

(Mentions of graphic violence, be warned)

After the school day was finally over, it was time to head to the nurse's office. Aizawa held his hand out for you to take, and off you went. It was oddly quiet for after school, and you had time to look around. Everything was bare and uniform, almost boring.
You stop in front of a white door, and Aizawa knocks.
"Yes? Come in, I was just about to leave." An elderly lady's voice sounded in your ears.
"Well, I'd suggest you stop, I've got a special case today and need your help with a kid I have. I trust you more than hospital doctors anyway." Aizawa said, making the woman look up.
"Ah! Aizawa! How good it is to see you. Is this the special assistance needed?" She points to you, who hid behind Aizawa's leg. She smiles delicately at you and motions for you to join her. You look up at aizawa for approval, and he gently nudges you to follow her. You follow Recovery Girl to a changing room and follow her to change into a gown. She takes notes on all the scars she sees and motions you to follow her to a bed.
"Based on what I've seen already from them changing, they were subjected to heavy physical Ab*se. The bloodwork would tell me what things those monsters put in them." She said, getting a needle. You start to panic, and Aizawa is quick to calm you down.
"Hey, kiddo, it's ok, I promise. She's just taking a sample, ok? Look, it's not even that big." He points to the hair-thin needle Recovey Girl is holding. You look away as she puts the needle in. It hurt a little, but it was over rather quickly. You didn't dare look at your blood moving through the tube.
"That's a good kid. You're doing great, sweetie." Recovery Girl says before taking the sample of blood to a machine. She puts it down and comes take the IV out.
"Oww.." You said quietly, Recovery Girl just smiles and kisses your arm, healing it. You look down at where the needle was inserted, and there lay a new needle mark.
"Hmm, I'm surprised you didn't fall asleep like others do when I use my quirk. That's special." She said before continuing to put samples into different machines.
"One will tell me your dna and family, another will tell me your quirk, and the last one will say what has been in your blood in the last month."
"Last month? Wow, that's certainly an upgrade." Aizawa exclaims, rubbing your shoulder in reassurance. As they were waiting for the results, Aizawa told Recovery Girl all the things you did since being with him.
"That's quite the few days for you, bet it's different from your life before." She said before 3 different machine chirps were heard.
"Oh, it's finished." She said, heading over to read the results, Aizawa also follows, not far behind. Looking at the results, a frown finds its way onto the nurse's face.
"Oh my, it's worse than I initially thought." She said before printing out a copy of all 3 results to Aizawa, who took them with caution, then read the contents. His eyes stilled as he read the reports.
"Kid, you were... tested on?" He asked cautiously. The bloodwork came back positive for quirk activators, deactivators, and amnesiacs. It also displayed when the possible last time it was administered to your blood.
"A week ago, but it was such a low dose, the machine almost missed it." Recovery Girl said, finishing the report. Aizawa flipped to the next page for any familial matches.
"All either deceased or unknown. They were murdered 2 years ago, family was killed, and child missing. It turned cold, but now it can be reopened." Recovery also said out loud. Aizawa was focused on the name. It was the same name you said that night after your nightmare.
"Kid, your name...is (y/n) (l/n)." He said before turning to you with a slight smile, now happy you know your name. You were just sitting on the bed, remembering everything.
"What..what's my quirk?" You struggled to speak after getting all this information. Aizawa looked at the paperwork, and what he said triggered all your memories to come flooding back.
"Chainsaw." (V*olence, be warned)

A flash of all your memories came back. You could hear yourself screaming,'No, I don't wanna!' And 'let go!' It was torturous. People in masks would inject something into your arm, making you lose control. The next thing you see is bl**d splattered on your cell wall. And rags of clothing belonging to those who injected you, and a revving of an engine. You were subdued and injected with something else before falling asleep to the next memory. They would hit you with things to try and activate your quirk, not caring if it hurt at all. You heard your name being called out repeatedly....

"(Y/N)!! Talk to me!" Aizawa noticed your panic attack and immediately acted. The recovery girl stood on the other side, waiting.
"Hey, it's ok, it's all over now. You're at UA. You're safe." He kept murmuring in your ear as you stopped shaking. Your breath was still sporadic, and you were shaking uncontrollably. Your shaking slowed once you felt Aizawa hug you tightly. Recovery Girl smiled sadly.
"If you wanted to try and train them, just know that their quirk is a mutation quirk, so even if you use Erasure, it won't work." She said before leaving the two of you on the bed. You stay there, hugging Aizawa as your breathing slowed, the silent halls of UA giving a sense of comfort. You stayed like that until Aizawa carefully lifted you up and left with the paperwork in hand. He would have to talk to the pro heroes about this and AFO in your dream.

It was about 6 p.m., and Aizawa was debating on leaving you with Class 1A dorm for a couple hours to talk to the pro heroes. He mindlessly walked there with you in his arms, still silent from earlier. He petted your head softly, which made you flinch greatly. He lowered his hand and apologized. You were still silent, but a grab of his shirt told him it was ok. He walked up the stairs into the dorms and opened the door to a couple of students studying, mainly Kirishima and a really pretty girl, Momo. The two look up and greet Aizawa.
"Good evening, Aizawa-sensei. Is there anything you need?" Momo asked politely. You move your head to look at her, but immediately put your head back down onto Aizawa's shoulder.
"Can you call your classmates down? I need a favor from all of you." He asked, and a few minutes later, everyone was called down.
"Now, I'm going to say this once, so pay attention. I need to chat about something to the other teachers and heroes, and I can't bring (y/n) with me, so I'm asking you to look after them for a few hours. They just had a panic attack earlier, so be careful." He said, setting you down.
"They don't really want to talk right now, but give them comfort and whatever, and maybe they can open up a bit, I need to go." He said before patting your head and leaving. You silently look at him leave before turning to the class. Among them were colorful and unique looking kids, like Pinky or known as Mina. There was also a kid who had 6 arms, Shoji. And a bird man who had a bird shadow, Tokoyami.
"Hey kid, nice to see you again." Kirisima smiled a toothy grin, making you nod in 'hello'.
Momo came up and lifted her shirt to her stomach, making a stuffed animal for you. It was about half your body size and a white bear. Your eyes glowed as you watched it be made.
"Whoooa." You exclaimed, watching Momo use her quirk. She gave the teddy bear to you, and you thanked her. She smiled sweetly at you before the others introduced themselves. After learning everyone's name, they asked what you liked and disliked.
"I like the moon." You said while looking down and smiling. Kirishima chimed in,
"Tokoyami likes the moon too! He made his hero name Tsukuyomi, the God of the Moon." His comment made Tokoyami ruffle his feathers in embarrassment but quickly regained his posture. Your eyes filled with curiosity on the hero names everyone had. Everyone said their names, and soon, Mina couldn't hold back anymore and asked what your quirk was.
"What's your quirk, honey? I'm ridiculously curious!" You give her a scared look, but look away as you said it.
"Chainsaw. Don't know what it means or what I can do, though." You smush your face into the teddy bear, anxious aging thinking about what happened earlier. Jirou noticed and brought up another topic.
"Why don't we girls paint our nails tonight? It's fun and harmless for a kid. Wanna join?" She asked, turning to you. You had no idea what 'painting your nails' were, so you were curious. And thus ensued a night of painting nails, making cookies, playing video games, or watching, since someone would mess everything up (courtesy of denki using his quirk accidently), but the night was fun and soon, you were tuckered out, and bundled on the couch. All the students ventured off into their own room, except Momo, who was watching you until Aizawa came back.
Aizawa quietly entered the dorm, seeing you tuckered out on the couch with Momo watching the door.
"Hello, sensei. How was the meeting?" She asked sweetly. Aizawa picked you up with the bear, and answered,
"There's going to be a class watching in a few days of how Nomus are made, be prepared to take notes. How were they?" He asked about your behavior and his class's behavior. Momo smiled at his misdirection of the question.
"They were very curious about everything, and only one accident occurred, but it was denki, so I'd say it was successful." She smiled sleepily. She gave a goodnight wave and headed to her room.
You were passed out on Aizawa's shoulder as he went to his own teacher dorm instead for the night. He headed up the stairs and to his dorm, and opened the door with his key. The room looked the same as he'd left it the last time; simple. He put you on the bed before changing into sleepwear and joining you. Falling asleep, he wraps you into a hug, with the stuffed bear in the middle.

"Goodnight, kiddo."
