My Little Devil <3. Katsuki Bakugou × Oc

~The beginning~

Age: 4

Ash's POV
It's my first day at a school, mommy and dad (I'm not putting daddy, my brain is to dirty >///<) said our neighbors have kids my age that are going to the same school as me. I saw both of them, one has ash blonde colored hair and crimson red eyes, and the other has green hair and emerald green eyes, I thought they look really cool.

~Timeskip~
I'm finally at school, I can see both boys, but mom and dad are telling me something. "Be careful, and don't get hurt." Mom tells me, "Don't misbehave either." Dad warns, and I try and talk, but... "I love you-", but when I open my eyes they were already in the car. I ignore it and walk over to the green haired boy, "Hi! I'm Takashi Ashlyn, I'm also your neighbor, what's your name?" I stick my hand out for a handshake while smiling, "Oh, hi, I'm Midoriya Izuku, it's nice to meet you Taka-chan!" Izuku shook my hand. I then saw the blonde haired boy, and continued to bring Izuku with me to introduce ourselves to the other boy, "Come on Izu, let's go say hi to him!" I said while smiling. We make our way over to him and stop in front of him, "Hi! I'm Takashi Ashlyn and this is Midoriya Izuku, we are your neighbors, what's your name?" The blonde haired boy looked at both me and Izu, and Izu waved at the other boy. "I'm Bakugo Katsuki." He says, then our teacher tells us it's time for a story, and I grabbed Bakugo and Izu's hands and dragged them to sit next to me on the carpet.

~Timeskip after the story into recess, brought to you by my lazy attitude~

Me, Bakugou, and Izu all decided to play hero, Izu and Bakugo were both heroes and I was the person they had to save, then we talked about ourselves. Me and Bakugo both like spicy things, we all like All Might, and I told Izu and Bakugo that I've met All Might, and they told me I was lucky, and then we went inside and did some other stuff.

-Another timeskip cuz I'm lazy rn-

I went home and tried telling Mom and Dad about my awesome day, but they had to do some hero work and I had to go to Bakugo's house. I knocked on the door and Mrs. Bakugo opened the door, "Hi, my mommy told me to go to your house because she and dad have work to do." I explain to her, "Oh, well come in, I'm just beginning to make dinner, and you can go hangout with Katsuki if you'd like. His room is upstairs, and his door has his name on a sign next to it if you can't find it." She says to me. "Thank you, Mrs. Bakugo!" I say to her with a smile, I was happy because she felt like a nice version of my mom. "Oh, you can call me Mitsuki, you don't have to call me 'Mrs. Bakugo'." She explains to me, "Oh, okay, thank you Mitsuki!" I say again, still smiling, and go find Katsuki's room. I found Kastuki looking at his All Might toys, "Hi, Baku-" "Hi, and you can call me Kacchan or Katsuki." I tried to say, but he interrupted me, "Oh, okay Katsu, do you want to play a game?" he said yes and we ended up playing tag in his backyard until it was time to eat.

~More timeskip~
Mom called Mitsuki and told her I could stay the night, and I just ended up borrowing some of Katsu's clothes.

~skip to after Bakugou gets his quirk, they are all 5 now~
Everyone always praised Katsu for his quirk, and others bullied Izu because he had no quirk, but I stood by his side no matter what. People were also mean to me..or just until Katsu got mad at them. One day I got my quirk though, "Ouch!" I yelped, " What's wrong Ash?" Katsu asked "My hand hurts- WOAH MY HAND HAS FIRE!" "Ash, you grew horns and a tail like a demon.." Katsu said to me with wonder in his eyes, as other kids backed away from me, "THERES A DEMON BEHIND HER TOO!" Some other kid yelled.

The teacher called my parents and told them I had gotten my quirk and that other kids were scared of me, so I had to go home early. 'Why are they scared of me? Did I do something wrong?...Am I a freak..?' I thought to myself in the car, when we got home my dad told me to train with him in our backyard.

(I'm not sure if this is when they start 1st year of Junoir high or not ;-;)
Age: 12
Ash's POV
It's been hard, Mom and Dad have been pushing me to my limits of my quirk during training..Mom punched me for the first time, and dad gave me a scar over my red eye after telling me that I was his and mom's biggest regret. I saw my new 1 year old little brother after though, I felt better after taking him with me to see Mrs. Midoriya and Izu, and Izu asked me about my eye, "Oh, I just worked myself to hard when I was training, that's all, heheh" I said as I laughed nervously. He gave me a worried and knowing look, but dropped the subject, and then I got a call from none other than my parents and I knew I had to answer. So I handed Izu my brother, Kai, and walked outside his room and answered it, "Where in the hell are you, you brat, and you took Kai?!" my mother yelled at me, "I'm at the Midoriya residence..." I said in a calm tone, waiting for the next things she was going to tell me, "You little shit, you can stay over there, but bring Kai home you fucking worthless peice of shit." at this point I had tears in my eyes, "Okay.." I said trying my best not to alert Izu or Inko that I was crying. I hung up the phone after they were finished telling me what to do, and walked back into Izu's room, "Hey, is it alright if I stay the night?.." I asked and Izu gave me a knowing look and then answered with a nod, "Of course, also Kacchan is staying as well if it's not a problem.." he says knowing that I haven't told Katsuki about my family, "Yeah it's fine, I'll be right back, i have to take Kai back and grab my stuff, see you when I'm done.." I took Kai gently from Izu's arms and started walking home.

~Timeskip~
As soon as I walked into the house Kai was taken from me and I felt a stinging pain in my cheek, and then a pain in my gut, my parents had both slapped and punched me. I ran to the bathroom and puked what felt like my whole dinner, and cleaned myself up, packed my stuff, and before I could walk out the door I heard my little brother crying and staring straight at me.

~timeskip to Izuku's house (Katsuki is already there)~
I knocked on the door with a tear stained face, and thankfully Izu was the one who opened the door, he brought me into a really tight hug, and i dug my face into his chest (yes, Ash is shorter than Izuku ;-;) then i heard Katsu yell, "Deku what the hell is taking you so damn long!?" Then I feel Izu get tugged pulling me along with him. Katsu saw me and I could tell his eyes softened when he saw my face, "Oi, you alright firework?" (he calls Ash firework bc she's his firework idfk bro lol) he asked me with what I knew to be worried eyes, I just ran up to him and buried my face into his chest (BaKuBoObS, I apologize I'm slowly dying ;-;) and he ended up carrying me to Izu's room with Izu following close behind. Katsu tried asking what was wrong when we were in Izu's room, but I didn't answer, after about 20 minutes Katsu asked again, this time i answered, "...Its a long story..." Katsu just looked at Izu, "Deku get out so she can explain why the hell she's in this dammed mood." with that Izu walked out of the room and closed the door behind him. Katsu looked into my eyes as I tried to look away from his eyes that reminded me of something I could get lost in and love it, 'Shit, I can't like him..he's by best friend and i-" he cut off my thoughts, "So you gonna tell me what's been up with you, or are you just gonna sit here?" he asks although it sounds rude I could tell he was worried. I took a deep breath, and explained everything my parents were doing to me, and he just looked at me with eyes I couldn't quite describe the emotion behind him though. When I finished I didn't notice I was crying, but Katsu continued to drag me down to lay in Izu's bed while he held me close and told me, "Its alright, if you would've told me sooner you could have stayed at my house...dumbass, you can't bottle up all this shit, you gotta speak up eventually." we need up falling asleep like that, I know because Izu somehow got a picture of Katsu before we woke up, I know it didn't go well because the picture was gone before I saw it and Izu had bruises, which I scolded Katsu about.
I hope everything stays this way forever, but I know life can be a bitch.
