Pinky promise (Izuku aka (Deku) midoriya x reader)

33.

*(y/n)'s pov*
It's been a a day and a half since I left. I didn't tell anybody, hopefully no one will come looking. I'm currently, walking to my little brothers room, I was told to train him everyday or, he'll be trained the way I was. I open the metal door to see the 6 year old in the corner. Though, me and Hide are related we look nothing alike. Hide has short red hair and black and grey eyes. "Hey hi~" "Why did you leave?" Hide cut me off. "Hide I had to." "No you didn't!" He said, with his eyes filled with tears. "Hide, I thought that you would be safer if I wasn't here." I tried to explain "I won't leave you alone again. I promise." "Pinky?" "pinky " I said and held out my pinky finger. He latched he's small finger with mine. He jumped in my arms and started to sob. "Please, please, please don't leave again!" I stroked his hair in an attempt to claim him down. "Shhh it's okay I'm not leaving without you this time." I whispered, it's funny sometimes Hide reminds me of Izuku. Hide looked up with his big eyes still watery. "What kind of training are we going to do?" He asked, his voice showed concern. I pulled out a safety pin. "We're going to practice pulling blood out of your body" I said, as I pricked my finger. Blood form the small wound gushed out. As the blood swirled around my hand, Hide looked in awww. "How did you do that?" He questioned "You have to focus on all the blood in your body. If not you can't get the blood out fast enough to weaponize." I explained "I actually have a guy friend who is having a hard time grasping that concept. Hehe..." I said scratching the back of my neck. Hide looked up and smiled. "(Y/n)'s gotta a boyfriend!" He beamed, as I chuckled. "He's not my boyfriend you dork. It's just Izuku." I heard a small gasp. "Izuku has a quirk!" He exclaimed, I chuckled through my nose. "Yep! Though... he can't quite control it just yet....." "Huh?" He breathed out "Izuku's just like me!" He giggled and jumped around. "Yep and just like Izuku your going to learn to use your quirk!" "Yea! Yea! Izuku's sooooo cool!..... s-so how am I supposed to start t-training like yours?" "I'm sure Izuku would love to hear that you look up to him. And give me your finger." I said as he held out his hand. I pricked his finger. As he focused on trying to bleed he asked me a question. "(Y/n), Yuki said mama showed you a trick with you quirk and fire. What was it?" I looked over to him, he looked so focused. "Hehe you remind me of Izuku you to should hang out sometime. And it's nothing really flashy I guess..... but I can hold alcohol in my blood." "Huh?! How do I remind you Izuku-kin?!" Wow..... he got angry fast. "It's not a bad thing. He's very focused.... and mumbly? Is that a thing? I'm n~oof" I was cut off by Hide jumping on me. "You sound like Izuku now! Looks like he's rubbing off on you!" "Heh heh I guess...." *knock knock knock* "Hum? I best get going Hide that's my alarm." I said, ruffling his wild red hair. "Y-you'll come back r-right?" "Of course mama needs me now" "Okay I'll see you later." "You too little guy focused on training for now." I said as I walked out. I still have to fight but as long as everyone's safe that's all that matters.
*small time skip*
Today I'm going out with one of mamas clients. We're going after the hero killer, apparently he needs help or something. We where on the rooftop when I heard a scream. "AAHHHHAHAHHHH!" Izuku? I started to panic when I heard..... Iida? What the hell? I ran to the noise. "Hey what the hell are you doing!?" Mamas junkie said "Honestly I don't know!" I yelled, I came to the edge of the roof and what I saw scared me. Izuku, Iida and Todoroki?! There his victims? I'm sorry mama I can't let this happen, they all look so.... so hurt, Iidas looks like the worst though. As soon as I saw an opening I jumped on stains back, taking him to the ground. "Hero killer stain! I don't know who the hell you think you are! But I swear to god I will kill you!" I beamed "what the hell I can't use my quirk?" Hero killer mumbled "lick my blood all you want weirdo my quirk doesn't work like that it's based on blood. You can't use it against me." I explained
*Izuku's pov*
I can't feel my body, it hurts everything hurts. Stain was able to use his quirk on me again, the only one standing up is Todoroki. "Hero killer stain! I don't know who the hell you think you are! But I swear to god I will kill you!" 'Huh I-I know that voice. It can't be? Can it?' I try to lift my head from the ground 'dammit! I can't move!' I heard someone struggling for air, as the effects of hero killers quirk faded. I looked up to see (y/n) standing on the back of a passed out hero killer. "(Y-y/n) it you?" She just looked around and used a chain to climb the roof. "N-no" I could feel hot tears welling in my eyes. Why? Why, can't you just be safe with me?! I threw my eyes shut and sobbed. Why? Why? Why? Why? *inhale* "Midoriya you need to calm down" Todoroki said "help is coming" "DONT YOU GET IT TODOROKI I CANT JUST CALM DOWN s-she's gone.... why can't I love anyone without getting hurt?" My sobs only grew louder. Why why why why why why why why?! I can't protect everyone else and not her?!
