BHNA X Sadistic Spidergirl reader

The day it all began

Y/N L/N a you daughter of the respected pro hero "Spidergal" the ambush hero was turning 5 today, she went outside playing with her friends a couple of people invited where her friends Kirishima and Mina she sat down on her feet dispite her parents telling her not to and blew up the candles in her cake wishing her quirk would arrive soon and when Y/N was asleep it happened her quirk began to manifest she began to get uncomfortable laying on her back so upon rolling over she relaxed, But when morning came the sleepy Y/N walks to the kitchen table she felt like she wastaller and kinda bigger her parents gasp at thier child before them and smiled "Honey your quirk is amazing!" She looked down and noticed her legs folded up and eight more on her sides a large spider abdomen just below her rear she looks up at her mom "mommy I'm a spider girl! Hehe I'm gonna be the next ambush hero hehe!" Whilst her father fed her her mother called ahead to the school to prepare the students for Y/N's quirk she faxed a photo over and smiled at her happy child "Mutation quirks are pretty common but yours us 1 out of a million kiddo" she clapped happily "Come on lets get you ready for school silly!" Her mom chased her to her room laughing as she took the sleeping gown off her handing her her shirt whilst quickly weaving a pair of specialized undies and helping her daughter put them on before her skirt completed the look all 6 of Y/N's shining red eyes glimmer with excitement and she squeals in happiness as she's taken to school like always with a piggyback from dad upon entering school she was told to wait just outside the classroom she heard the teacher explain "Y/N has gotten her quirk and I want you all to be polite! And tell her what you like about it!" They all agree and when Y/N walks in the first person to speak was mina her eyes sparkling "Holy cow! Y/N your quirk is amazing!" She smiles at mina and whispers a shy thank you before Kirishima spoke next "so! Are you like able to climb walls and make thread?!" He asked excitedly y/n nodded climbing up on the concrete wall with ease and began to weave a thread to the desk age sat in before it was pulled up and suspended by a web on the roof "Oh wow!" He called soon everyone was complementing the girl and she was probably the most excited girl to get a quirk until, a snarky girl said aloud "Spiders are gross!" Now since Y/N was only five this hurt her feelings but instantly Kirishima stood up defending his friend "HEY don't make fun of my friend cause her quirk us cool and unique!" She looks at her friend and smiled

But that was years ago Now, Y/N Was in middle school and busily working her hardest to get into the same academy her mom went to U.A. High she was so busy with her work she hadn't noticed that her little corner up in the library had become quite a popular spot that was until the power went out Y/N stood there quite annoyed at the power failure and pulled out the lamp from her bag and turned it on illuminating her work she was so busy working she didn't notice her two friends coming up, when she felt a vibration on her web she looks down to see them so she slowly comes down "guessing its lunch time?" She asks as the power returns they nod to her and she rolls her eyes as they climb onto her back and she tied thier feet and hands to her as she crawls out and soon is on the roof moving much faster to the cafeteria this was a normal thing with the trio Y/N ate above the two since she couldn't sit down there, she was eating her food quietly and a newer girl whom made herself popular made the mistake of making fun of Y/N and in meer seconds she was tied up and plastered to the roof The chilled words ringing out of Y/N's lips, "listen here you insignificant little worm I firmly suggest you keep your tongue clear of my name or so help me I will enjoy webbing it to the roof of your mouth..so Sit down and keep quiet fresh meat"  the girl sat there mortified as everyone began to continue talking "Y/N that was kinda uncalled for " Kirishima says " oh Kirishima I was only playing, its not like I was actually going to hurt her"the spikey haired male laughed slightly nodding "Yeah I guess your right...hey Y/N you gonna eat that salad?" She scowled at the bowel "For what in return?" She says smiling devilishly at the boy "I'll get you ice cream on the way home" her eyes widened "I'll get you a whole tray if you do that" she says bluntly and crawls into the lunchline asking for another tray and paying the needed amount before the tray lands before Kirishima "Don't be late Enjoy" she says before going to a empty part of the cafeteria and sighing softly bringing up her textbook and then continuing to study before a man approached her with a paper "L/N your paperwork is in order Your mother recommended you see you next year" the man looks around before yawning and then looks at her with his tired eyes "Don't get in trouble L/N" before walking out "Hey Y/N who was that?"A popular girl asked her "Apparently a Teacher At U.A, I was Recommended..to attend there" soon everyone was complement the girl telling her great job and well done Kirishima stood up "I'll be seeing you there!" Mina smiled "Ditto!" Before the day was continued Y/N told her parents the news and then they gave her a gift along with transfer papers "Sweetheart we love you, now its time for you to make your own life out there"the gift contained her clothing, a hand made card from them both, and roughly 6 million Yen "Sweety if you ever need help just come home " her mom says soon Y/N was on a train making her way to Musutafu Japan many people asked her if it was a cosplay but she told them it was her quirk and they told it the same thing everyone says "Unique" soon reaching her destination she took a small amount of money and rented an apartment and stocked it with food her neighbors the Midoriya's go to welcome her she happily accepts them in "I'm Inko and this is Izuku, Wow..I must say thats an impressive quirk its rather.." "Unique?" Y/N finished with a soft smile she nodded and smiled softly back "Midoriya-kun" Y/N states "Do you perhaps think you could lead me to school I have to finish up my semester here.." He nods and studders nervously making her smirk "Forgive me of I seem rude but I must be going to bed soon...I'll see you tomorrow Izuku"she says. He nodded as the family of two leave, up goes the hammock she smiled softly climbing in her bed soon falling asleep
