Aizawa x Child!reader (Chainsaw man)

Quirk Experience

It was a few days after finding everything out. You were still scared about your quirk, but Aizawa reassured you it was fine. He was gonna leave you in the care of the class again because of another hero meeting. The class was excited, but you felt a bit overwhelmed by the mass amount of voices and cowered into the couch. Bakugo noticed from the kitchen and made his way over to pick you up and bring you to his dorm.
"All you extras are too busy being excited while the kid themselves is about to piss their pants, maybe be quieter and you can have a good time, for now, don't bother coming to my dorm." He says, setting off an explosion in his hands to support his threat. Everyone backed away as he grabbed a few snacks and drinks and headed to his room.
Once in his room, he made a little chair on his bed, using the pillows and blankets. You sat on his lap, and he turned on his TV to a kids' movie.
"Hungry kid?" He offered oreos and a juice box. You take them with a small nod as thanks. He then reached behind his ears and took off a couple of little hearing aids. You look at them in curiosity.
"What are those things?" You say pointing to the hearing aids, Bakugo smiles and replies,
"These little things help me hear. My quirk is making me go deaf, so I have to wear these during the day." He smiles softly and pats your head before stealing an oreo out of the box. You look at his features as he's watching the movie with subtitles on. His face is gentle, and he doesn't have any hint of anger behind it.
You turn back to the movie and relax against him, munching on oreos and juice boxes. Together, you watched multiple movies until you fell asleep, cuddling his arm. He lifts you up and takes you to the common room, where Aizawa was waiting to take you back.
"Bakugo? What a surprise, what happened?" He asked as he took you from the blonde's arms. Bakugo shrugged and answered quietly,
"Extras were being too loud, and they got overwhelmed. We just ate snacks and watched movies." He shrugged, ready for bed himself. Aizawa nodded a 'thanks' and headed out.

Falling asleep in his teacher dorm, Aizawa thought to himself that it was time to see your quirk in action. The next day, during training, he decided it was time to face your fear or your quirk in this instance.
"Hey, kiddo, I would like to get a feeling of your quirk today. Would you be willing to activate your quirk so I know how to train you?" He asked while kneeling to your level. It was currently training time outside, so everyone was busy either exercising or sparring. You turn to him, fear a bit shown on your face.
"But what if I hurt somebody? I don't wanna hurt anybody with my quirk." You said worryingly. He patted your head reassuringly,
"No one's gonna get hurt, I promise. Now, how about you go to that empty space over there, and I'll tell everyone to move out of the way?" He asked. It seemed like a good idea, so you nodded. Aizawa then proceeded to call everyone's attention and move them away from the specified area.
"Alright, kiddo, the ground is yours." He said, gesturing. You nervously rubbed the back of your head, finding the pulling plug to transform.
You tried calming yourself, finding the peaceful moment in your mind. Feeling all your muscles relax, you pull the trigger to transform.
In a flash, metal wires creep out your neck, transforming your mouth into a razor-sharp trap. Your face is now covered with a helmet of sorts, with a giant chainsaw in the middle of your forehead, orange eyes glowing right behind the protective bars of the chainsaw. A cloud of steam exits your mouth. Your hands also transformed into a chainsaw, coming right down your middle fingers. The engine roars as you can feel the adrenaline rush through your body.
Everyone was shocked and stepped back behind Aizawa-sensei. Even Bakugo was surprised. Aizawa looked at your form, entranced by the razor-sharp teeth, with the whip like tongue dancing in excitement.
"Now that...is a quirk." Midoriya said, muttering. You stood there still as a board, but the engine revved in response.
Aizawa stepped forward to get a better look, still keeping his distance. He tilted his head to the right. You tilted to the left to mirror match him. He tilted his head the other way, and you as well. He smiles, and you can smell his happiness almost.
"Think you can transform back?" He asked loudly over the engine roar.
You relax your body as you take a deep breath in and let it out slowly, the metal melting away as if it were wax. Soon, your relaxed face was revealed, and you tripped forward, catching yourself, though. You smiled brightly at Aizawa and raced to hug him, now free of any chainsaws.
The students flinched as you launched yourself into a hug towards Aizawa, and he happily caught you and returned the hug.
"Did I do it?" You ask curiously. Aizawa nodded,
"You did, kiddo."
You grin brightly at him, and he laughed a little at how bright your smile was. All the other students move back into position and back to sparring one another for the rest of the day.
