Midoriya's POV
Shit shit shit shit. How am I going to get myself out of this mess. I should've known it was entirely possible for Shinso to ask more than one question. I thought maybe I'd be able to avoid answering by telling half truths but I guess my brain just came right out and said I got my quirk from All Might. The three people sitting in front of me seem to be quite confused, I mean I was too when All Might offered me his quirk. Clearing my throat I finally say, "Well I guess there isn't really a way around this but to tell you guys the truth...*mumbling*All Might is so gonna kill me for this."
"Hey Izuku, whatever it is we won't tell anyone so really there's no reason for you to be shaking right now. You can trust us. Right guys?" Y/n says as he gives a slight glare at Shinso and Todoroki. They both pipe in with a yes. Despite the confirmation I still feel scared since it isn't really my place to share information about my quirk at least not until it's fully mine. I take a deep breath and then ask to talk about this in my room where we wouldn't be overheard. They all follow me and I hide my embarrassment as best I can when their eyes roam over all the All Might paraphernalia in my room.
"I'm going to be brief with you guys since I'm not supposed to let anyone know about the nature of how my quirk came to be." I say as sit on the side of my bed. "My quirk is called One for All and it has the ability to be passed on through the consumption of the DNA of the wielder. I was quirkless until the day of the entrance exam when All Might gave me his quirk and that's pretty much why I break my body every time I use it because my body isn't strong enough for this quirk and I've also never had a quirk before so I couldn't even guess how to use one properly. It is also why Bakugo hates me so much because we've been friends since we were little and he thinks that I've been lying about being quirkless my whole life. That being said All Might told me I couldn't tell anyone about my quirk because of the dangers that would come with people knowing that this power could be passed on to others. You guys are seriously the only people I've told... I haven't even told my own mom about it because I didn't want to risk it."
The silence that embraces the room after I finished talking was painful. I honestly didn't know how much I could trust all of them with this secret but I had no choice since I couldn't turn back the clock or erase their memories. "So you're actually just like All Might's successor?" Todoroki asks. I simply nod as Y/n comes over and gives me a pat on the back. "Who would've thought that All Might's biggest fan would get to have his quirk given to him? I'm proud to call you my brother Izuku even if All Might only gave you his quirk because you didn't have one... knowing you you probably cried about it... a lot." He lets out a small chuckle and then adds, "You should probably ask All Might to let the faculty or at least some of the faculty know about your quirk. They're asking you to train with a quirk you don't know how to use, since you got it really recently, as if you have had it your whole life. They might change the training drastically if they knew and it would cause you less bodily harm."
I contemplate what Y/n had said and I realize he is right. Because no one knew that I got this quirk a few weeks ago it was putting more stress on me to act as if I knew how to use it. It wasn't like the teachers, who are pro heroes, would tell anyone else about my quirk being from All Might, right? I nod and decide that I would ask All Might about it, not really sure if he would agree because he didn't really like Aizawa Sensei all that much and he is our home room teacher. Would I just tell them anyways? I might because this is technically my quirk now and if I get to train properly it would be better in the long run. I also trust Aizawa a lot especially since Y/n is his son so he's kind of like family in a weird way.
Y/n's POV
I'm glad that Izuku told me about his quirk. It's kind of amazing that the number one hero gave his quirk to a quirkless boy who wanted nothing more than to be able to be a hero. Wait does that mean that All Might was quirkless before he got this 'One for All'? That would explain why giving his quirk to Izuku would leave him with less and less power. I'm not as dumb as other people in my class I know that All Might has two forms, it is pretty obvious. He always is in the teacher's lounge out of 'muscle form' and he is always running off as soon as class is over. Not to mention the concerning amount of blood he coughs up sometimes. I swear my classmates are just blind.
The rest of the sleepover goes smoothly and soon we were all headed home after lunch the next day. It was safe to say everyone had fun and got to know each other a bit more. On my way home I stop at the pet store to pick up some food for Lev. When open my front door Lev bounces up to me and circles my ankles making me almost trip. I chuckle a bit before picking him up and placing him in my hood so he is out of the way for now. I quickly dish out his food and water before heading to my room. I cuddle with the kitten for a bit until I hear the door open downstairs.
It was most likely Aizawa that came in the house but my brain told me to be prepared for anything so I simply sit up in my bed and get my scarf from off the door over using my quirk. I wrap it around my neck and slowly opened my door with my quirk and gently push Lev towards the door. "Go scout it out for me Lev." I whisper as he tries to curl back up in my lap. With a small tilt of his head he looks up at me. "Go." He finally seems to understand and slowly makes his way out of my room and towards the stairs.
I hear footsteps come up the stairs and Lev speed walks back into the room and onto the bed before curling back up in my lap. That's a good sign right? Surely the cat would be more on guard if it was a stranger in the house. I relax a bit still holding the ends of the scarf as watch a figure come into the door frame. "What no hello?" Dad says with a small smile. "You know that scarf won't do much if you don't know how to use it without your quirk. Dad's eyes flash red as his scarf wraps around me. He pulls me off the bed, letting me go so I could catch myself before I face planted. "Don't think that just because you're in school now that it means you stop training with me. Get up and get changed we'll double the training today since you missed yesterday's. I'll be outside waiting."
As soon as Aizawa is out of earshot I groan. My face is still hot from the embarrassment of almost face planting. I get changed quickly into something light and breathable and then make my way outside dreading training and yet knowing if I take too long that Aizawa will just make the training harder. We both warm up a bit doing a workout and stretches. Afterwards we do some sparring without quirks, just some plain hand-to-hand. The amount of times I land on my ass is a little concerning. Breathing heavily I get back up to see Aizawa barely breaking a sweat. I've been slacking off with training recently which Aizawa allowed only because therapy sessions were held after school when we'd normally train and now I'm paying for it.
We take a quick water break before going back into the sparring ring and this time using our quirks. I knew my dad got serious dry eye whenever he used his quirk and since we hadn't brought objects into the ring to use, all I have to do was stay out of his reach until he blinks. Dodging takes quite a bit of energy but my focus is mostly on pinning Aizawa to the ground with my quirk. Soon enough he blinks and is trapped on the ground for a brief moment in which I get on top of him and pin him down so he can't move even if he erased my quirk. He tries for a moment to flip me off of him but he realizes he can't and taps out.
"Since you've seem to have taken a liking to the scarf I gave you I guess I should actually teach you how to use it properly." He chucks the scarf at me before grabbing his own and putting it on. "Don't use your quirk to control it. That'll take too much energy out of you." He says before directing me how to hold it. "And just a head's up, it took me six years to learn how to control this scarf/fighting style so if you think something else might be better to learn we can always switch to that."
A few minutes later I am self debilitated as I clearly failed at controlling this stupid scarf without my quirk. I'm pretty much trapped in my own weapon. I try pushing on it and end up getting more tangled. Stupid scarf. I look over at my dad to see him shaking with barely contained laughter which stops as soon as a very loud presence makes itself known before even entering the backyard. "HEYYYY What's going on over here?!" I groan at the fact that Yamada is also going to see me struggling to master this scarf. As soon as Yamada sees me he bursts out laughing but not entirely at me cause I notice Dad go a bit red and looking literally anywhere else. "Do you need some help kiddo?" he offers before adding, "You know your dad used to get stuck like this all the time and one time he was stubbornly stuck in the scarf for a whole day until he finally relented and asked for my help. He was a little embarrassed at his predicament at the time but he also didn't have anyone to teach him how to use it either."
I shake my head, declining his offer of help, if I really want to get out of this I'd just use my quirk which I proceed to do. I expand the scarf enough that I could get out before I let it crumple to a pile on the ground. "Dad didn't happen to mention that fact. Laughing at me is a little contradictory don't you think." I give a playful glare at Aizawa and stick out my tongue. "At least I can get out of it without help, unlike him." I dodge his scarf laughing and hide behind Yamada. "He isn't lying you know just stating straight facts." Aizawa scarf wraps around both of us as we laugh together at him. Pulls us forward quickly causing us to trip and land on the ground. He looks down at us menacingly before he states that we tell no one else about his previous difficulty with the weapon. We both nod, slightly intimidated, since he knew how to make both of our lives hell. After that whole fiasco ends we head inside for a nice 'peaceful' dinner.
