BHNA X Sadistic Spidergirl reader

The USJ attack

Following Aizawa and her group left her feeling something could go wrong at any moment and when she looked around her mind told her to find a dark corner and wait, she soon did so as a portal opened up villains began to pour out Y/N then began to lay an intricate trap as a monstrous beast walks out the portal so in followed by a man covered in hands Y/N couldn't hear his words but as Aizawa took off after the villains Y/N followed soon, seeing her friends trapped and teleported to different areas but once Y/N was above the masked man she sprung her trap ensnareing the man of hands bringing him up "Give me one reason not to snap your pathetic little neck" she tasks in his ear "Because....I'd hate to kill such a beautiful young girl" Y/N scowls dropping the man from the roof area dhe was on enjoying the sound he made as he fell soon she slowed his fall enough to where he hits the ground with a rough thud he got up with a seething hiss "Nomu! Kill that Eight legged bitch!" The said monster dropped the broken Aizawa like a twig jumping up after the spider girl only to be stopped by her secondary wave of thread leaving the monster suspended in mid air giving her time to retreat to a dark corner the monster broke free from the binds and fell to the ground and jumped after her again this time grabbing her by the throat and slamming her to the ground a pained growl left her lips as the nomu flew back from her legs force she quickly scrambled back upright before the beast was after her again this time she was ready catching its arm and latching onto him from behind attempting to restrain it with thread when she thought it was enough she leaped away to her friends who held the warp gate down, as the Nomu broke free all might arrived to stop yet another blow the injured girl hand retrieved Aizawa and began to field dress his wounds covering him in thread stopping the bleeding and and slowly wrapping his limbs tightly to make them stiff blood running down the side of her face as blood leaked from her abdomen from where she was slammed and after Aizawa was bandaged she couldn't make anymore thread "I cannot produce anymore without food..." She says as she finished up with Aizawa to see All might starting to steam "Hmm...interesting.." She mumbles as paramedics arrive checking on her after they take Aizawa "Where are you hurt ?" One asked her "My Abdomen...I believe that fall broke the exoskeleton a bit..." She says as her face was wiped she felt a kiss on her forehead
Soon her abdomen she notices the old woman before yawning "Why am I suddenly..sleepy..." She says yawning again showing off a mouth full of razor sharp teeth her eyes slowly closing as she fell asleep chest first on the bed next to Midoriya who arrived after her, when she awoke the next day her body reminded her of her current need, Food so heading to the cafeteria she noticed other students already there it was lunch time already? Jeez.. She looks around as she walks to the line asking lunch rush if he could pile on the meat since her quirk required her to eat to produce thread and soon Y/N was carrying a massive amount of food on her tray as she sat down beside her classmate who all asked her if she was ok she merely nodded to them and then looks to bakugou "Good job saving our class bakugou..." Everyone froze as he smirked"I told you Number one..And next timw dont be stupid when fighting" he warns she simply smirked "hmm.." Was all sge said before she heard a horris voice call out "So this is class 1A? I'm not impressed,oh? Wait your that girl who saved Aizawa! Oh your just as pathetic for being in this class instead of mine hahaha!" Before anyone could stop bakugou from talking Y/N was up towering over monama a dark aura filling the room as she grips his face roughly "listen wisely meatsack...I will make your time here a living hell..if you dare insult me or my class again, I swear to god..I will make you regret it now be a good dog and run back to your masters before I rip off your leg and beat you to death with it...Do you understand me?" the make before her nodded trembling slightly as she grips his face tighter releasing him and watching him stumble away screaming about how her class was the worst she sat back down and bakugou laughed "Way to show that dumb bastard to mess with me!" He says only to be groaned at by many as Y/N continued to eat only to feel a happy aura behind her "Hello mom" she says as she's hugged from behind "Hi my little spiderling!" Izuku's eyes widened. As everyone asks at once "Your mom is Spider-girl?!" She nodded to them "yes.." Her mothers bright aura fills the room "So I heard on the news you saved your teacher and fought a really dangerous Villian!" She says as Y/N nodded "Thankfully all might had arrived in the nick of time to save us" she says softly soon as the bell rang her mother follows her to class along with midnight the girl took her place up in the corner "Ok...first order of business the U.A sports festival..its continued" Aizawa says still covered in bandages but once everyone noticed midnight move in the room they all blushed or wowed then as Y/Ns mom came in they all waved and said hello "Today we will pick hero names!!" Everyone but Y/N was excited about it, Y/N however already knew whst she would be "ok who wants to go first?" Y/N raised her hand and then slowly walks to the front board in hand "The nightmare hero: Rachnera.." Midnight smirked "ooh so you'd be like a Noir hero huh?" She nodded "What caused thus name choice?"  "well as a fellow sadist I'm sure you'd see I don't mind hurting villains to put them away" she swore she was midmight shiver in glee "Well done! Who's next " Y/N tuned out the rest of the people until her mother spoke "Listen up since you all know I'm Y/N's mom I'll tell you why Y/N's hero outfit isn't completed yet..since Y/N is a larger girl we had to specially make her outfit by hand and here it is " her hands held a solid black outfit it had various armored plating designed to protect her abdomen and legs "Oh wow!" Everyone says as she handed Y/N the case her eyes finding her daughter's with a small smile of thankfulness, her mother then swings out an open window yet again and soon everyone looks to the open door where 1B stood "This is 1A? What a dump" Y/N smirked her evil aura surrounding her as she perches over the door and slowly lowers down smirking "well well...Fresh meat...Ripe for the taking, you know its not hard to crush human bones right? Maybe I'll crush one of you then you'll scream as I slowly watch you move around pimply begging for mercy of the sweet sweet sounds of agony I'll hear your screams a symphony to my ears and when I'm done playing with you I'll throw you all away like the low level trash you are." Both classes went white from fear except Bakugou, Todoroki, and Sinsho they all stared in disbelief or blankly as Y/N was almost dragged away by Midnight who's cheeks where dusted pink "Sadisum at its best eh L/N...Are you sure your not an 18+ hero? " she asks jokingly only to receive the same dark glare "Never in a million years" Midnight shivered at the tone and nodded as she began class, Y/N returned to her corner and a smirk appeared on bakugous face he might just have to ask Y/N for some coffee to May be strike up a partnership and he played it over in his mind the Number one hero partnered with the number 5 hero the possibilities would be endless..and the capture rate of criminals would so high its unreal so after class bakugou marched up to Y/N "Oi spider! Come with me and get some coffee or something I wanna ask you some questions!" With a short nod Y/N follows bakugou and upon reaching the coffee shop YN orders tea "Why no coffee?" He asked "Spiders get drunk off caffeine" she says softly as she looks at him "now what is it you wanna know?" He nodded "Your my partner now and when we become hero's we are gonna be partners and be the best hero's ever got it?" The girl smirked giggling "WHATS SO FUNNY?!" He snaps "So..what your saying is that you wanna go out with me?" His face turns into one of shock before a light pink dusts his cheek as he mumbled stuff about stupid girl and murdering something, the girl simply smiled as she sips her hot tea "Whatever lets go meet the hag" y/N nodded following after paying for the tea her portable cup in her hand as she follows bakugou before reaching his house "Don't move" he says opening the door to hear yelling "WHERE YOU BEEN BRAT?!" "SHUT UP YOU OLD HAG I'VE BEEN TRYING TO GET TO THE TOP!" He snaps Y/N gets noticed at the door "Katsuki who's this?" "She's my fucking girlfriend" the woman's eyes widened before she rushed the door pulling Y/N in "This is odd.." She mutters "hi I'm Mitsuki.. Uh quite an interesting quirk you got there" Y/N nodded to her "So between you and I just so we know what to expect to end up seeing..where's your..uh you know?" This stunned Y/N hut she answers "The front..Although I have another set of lungs and another heart to help me breath, and get blood around" mitsuki nodded to her"HEY QUIT MAKING THINGS AWKWARD HAG!" "SHUT UP KATSUKI !" Mitsuki shouts as Y/N is lead to Bakugous clean room "Hm..not what I expected.." She noticed the all might figurine and smiled "Awe how cute" she looks at him to see him scoff "Shut up spider.."  He grumbled "your mother is odd.." He nodded as he did his homework "Hey..why did you thank me today?" He asked facing her "You protected out class and helped save Thirteen whilst I saved Mr. Aizawa" he scoffed "you almost got murdered" she shrugged "Then you must have been happy when allmight saved me huh?" "Hell yeah! ALLMIGHT IS THE BEST BUT IM GONNA SURPASS HIM AND THAT IS GONNA BE MY SPOT!" She nods "I believe that you can do if you put your heart to it" she says to him and began to leave "I'll head home now" but not before planting a small kiss on his cheek before walking out to her own home, upon reaching her apartment she quickly got into the bed and fell asleep
