BLOOD SIBLINGS

CHAPTER 1

AN: HEY GUYS SO JUST SO YOU KNOW THIS STORY IS ACTUALLY A COLLABORATION BETWEEN ME AND Takasu-Hoshikaen10. EVEN THOUGH I DO ALL THE TYPING WE POOL OUR HEADS TOGETHER TO GET SOME GOOD IDEAS DOWN. SO I HOPE YOU ALL ENJOY THIS.

AT QUIRK COUNSELLING

It was just another day of tedium for a certain daughter of a certain well off family. It was always the same formula of school, group session quirk counselling twice a week, gymnastics the other five days, and then home. Today was another day of these same dreary and vomit inducing sessions with these idiots. Her parents told her to keep the blood part of her quirk a secret, which in her eyes defeats the whole purpose of sending her here.

All these cry babies were same with their stupid problems, each one dumber than the last.

"People laugh at my mutation quirk."

"My quirk is so weak it gets ignored by everyone around me, even during quirk assessments."

"My quirks use is so specific that it useless in like, almost every situation I find myself in during the day."

These were the complaints that people came here with everyday and you know what? Except for the mutation quirk user, all the others are so pathetic to go on like this to others. Sure your quirk was weak or mostly useless, but at least you are not treated like a monster for it. And the counsellor himself, was spouting nothing but absolute crap to every single one of them.

Your quirk just takes away from your other features, you just need to get those to show more. Even if your quirk is not flashy, that is the hand you were dealt with so you may as well make do with it. Even if it only seems to have a single use, I am sure there is a job out there with a use for it if you look hard enough. These are the things he would tell, he was one of those people who did not believe in quirk evolution. I mean come on, a quirk is not a magical gift, it is something that grows with you. That means you can train it to become stronger, well in my case that would be a bit difficult but still it is possible.

It is no wonder that nobody here is making any progress with their quirks with him. He is a brick wall when it comes to this stuff, and on top of all that other crap instead of helping them with their emotional problems like he is supposed to all he is doing is telling them to be complacent and just stick to finding a mediocre role in society.

I once said I wanted to be hero and I cannot believe what he told me when I said it. He said that I was aiming too high and that it be more useful as a police officer. Apparently if a quirk is not flashy then it is not suited to be a heroes quirk, as flashy was a job requirement. There are plenty of heroes with non flashy quirks, like Eraser Head who nullifies quirks. Sure he has to use martial arts to fight to make for a lack of quirk attack, but his quirk makes it so any opponent who relies on their quirk is helpless.

TOGA HOUSEHOLD (13 YEARS OLD)

She had finally got home for the day and as always had to report to her parents that her secret was safe. Once they were done questioning her they sent her upstairs to do her homework. She swears at this rate she is going to go nuts, so she went to her drawer to grab her knife, however it was gone. Normally she would give herself a little cut every few day and lick up the blood, then bandage it up so it would heal within a week or so before cutting herself there again.

Did one of the maids notice her knife and take it from the drawer? Did they tell her parents they saw the knife among her things? No, if they did her parents would have said something to her earlier. All the current staff except for the head maid and head butler do not know her true quirk. The only people aside from her parents here were those two, so does that mean one of the new servants did it?

If so she could only imagine they did it to try and help her, from doing what they thought was suicide. Unfortunately in their attempt to help her, they only made things worse for her as she now must procure a new one. She barely snuck that one past the servants and up to her room the last time she did it. But lately the head maid had been keeping a close eye on her. So now it was impossible to do it again. That was when the door was knocked on and the new maid, called Aiko asked to come in. She had black hair tied back into a pony tail, and a large bust that was barely contained by her uniform. Her eyes were the colour onyx, a powerful shade that made you lose the will to resist when you looked into them.

I told her to come in, even though she was new she treated me much better than the other maids. Not to say the other maids were rude or mean to me, they just ignored me when I asked them to sit down and talk with me. Aiko on the other hand came here whenever she had free time or was on her break to talk to me.

I admit it did feel a little weird at first how she would blush sometimes and just stare, but hearing from her what it was like to have grown up in a normal family and not have to hide your quirk was nice. Well I guess I was wrong earlier, there was one other who knew my secret and it was her, but she was not scared of my quirk. Rather she said it beautiful, how my quirk could turn me into anyone I wanted. She said how it must have been nice to be able to understand people you care about by seeing the world through their eyes.

That being said something felt a bit off with her today, for some reason my instincts were telling me to run. She took her usual seat on my bed and I sat beside her, for some reason nervous trying to ignore my instincts. "Such silky hair… such sharp looking cat like eyes." Aiko said sighing as she stroked my face. Okay, this was starting to get weird, maybe I should get back to my studies now.

When I tried to get up she pulled me back down onto the top of the bed laying me down. She then flipped over and was straddling my waist as she looked down at me with a look I never seen on her face before. "I am finally going to enjoy myself after so long, and with your parents blessing." Aiko said licking lips. What did she just say! My parents gave her permission to do this to me! What the hell is going on! "Your panicked look was quite enjoyable when I came in, taking your knife was a good choice after all." she said with some sort of pride. So it was her who took my knife!

Aiko had gone to her employers a few days ago to ask them a question about their daughter. She had asked them if she could use their daughter and unleash her carnal desires. At first they laughed at me and told me to get out, until I mentioned their daughters quirk. Once I did they told me I could, so long as I never revealed that information to anyone.

And now she was here about to enjoy her, Aiko spent months getting to know this angel before. A master servant relationship was taboo enough, but this girl having a blood quirk was even more so. To have such a beautiful smile and such a disgusting quirk, this was the epitome of gap moe. She had to have her, there was no way she could ever bring herself to pass this up, so she finally began.

Toga was confused and tried to break free from her but lacked the strength to do so. This person who she thought was her friend… only wanted her for her body this whole time? Why did Aiko ruin this, her first real friend was nothing more than crazy pervert? She was heartbroken and her mind went blank, unable to process what was happening she escaped reality.

Aiko was in the middle of licking and nibbling her ear lob when all of a sudden she stopped squirming. She thought her young master had finally come to her senses and accepted her love, but when she got a look at her face she saw a pair of hollow eyes reflecting her own. "So you are unable to accept my love… oh well, you will accept it soon enough." She said continuing on to force her tongue into her young masters mouth. Partially enjoying the sloppy kiss that they were doing right as she moved her right hand to between her lovers thighs. However something she did not see coming occurred when she started playing with that spot down below.

Toga retreated to the back of her mind and was only able to see a deep blackness all around her. She was standing on a white flat surface when something began approaching her. As it got closer it began to take on a more solid shape until, it became a copy of her.

Though it was far from a perfect copy, her hair was tied into two messy buns. While her current hair was long and loose, also much more well kept than this version of her. This copy of her had a baggy sweater over her school uniform, with dark shadow under her eyes. Her on the other hand owned no sweater matching it and she did not have shadows under eyes. This copy of her gave a feral grin and began calling like a mad beast causing her to step back.

"Come now, cat got your tongue?" The copy of her asked swinging her arms behind her back. She eyed Toga as if she was a predator deciding wether or not to attack the prey before them. "I am here to help you, not harm you sweetie." She said putting her face a mere inch from mine.

"What do you mean by help me?" I asked getting weary of her closeness. If I give into her I can already see the downward spiral I would end up taking, but at the same time there was something I needed to ask her before this continued. "Who are you?" I asked as she took a few steps back and giggled like an innocent child.

"Let me take over and I will help you out of this situation you are currently in." The copy said tilting her head sideways. If she is telling me to trust my future to this maniac, I would rather endure this sexual assault/betrayal. "As for your other question…" she said pausing to half close her eyes as she gazed upward at me. "…I am the physical embodiment of your quirks desire for blood, but you can call me Doppel-chan." she said, sneering at me with pleasure.

So she was just my quirk manifesting, the thing I had been suppressing all this time. Should I take her up on her offer, will I really be unable to get myself out this without her? What do I really have left to lose now after my parents had betrayed me like this? "Okay but after we are a safe distance from here I will take over again." Toga said agreeing to her terms and shaking her hand.

Doppel-chan had taken over in the middle of the sloppy kiss she was receiving and decided what to do. Once Aiko tongue was deep enough in her mouth she bit down on it drinking her blood and saliva. Muffling the maids scream with her own mouth she used the distraction to grab her hands. With them held behind her back and their legs holding the others tight she was soon drained of enough blood to die.

One moment Aiko was enjoying the kiss she worked so hard to obtain and the next she was in incredible pain as her young master was biting down on her tongue drinking her blood. She tried to scream for help but her voice was muffled due to the deep kiss she was doing before. When she noticed her eyes a chill ran up her spine, those eyes were not the shy girl she knew. It was the eyes of a cat toying with a mouse before devouring it whole, here she thought she was the cat.

Turns out she was actually the mouse squeaking for help hoping someone would save her from getting eaten. After a few more minutes her tongue was severed and she was flipped over onto the bed. Now choking on her own tongue as she was straddled by the girl she was doing too before. Such thing were her last thoughts before she had finally died by the hands of the one she loved.

Doppel-chan had stopped once she knew the maid was dead then went to work. She stripped both herself and the maid before Turing into the maid, then put on the maids clothes. She hid her sideways underneath the bed sheets and then went to complete her work. She payed a visit to the soon to be empty safe in the office of her quirk users father and took out all the money he had there.

Then hiding it under the maid outfit she made her way to the maids live in room and decided to change her clothes. Then retrieved her quirk users backpack and a few set of clothes before proceeding to the kitchen, where she grabbed as many knives as she could fit in her bag along with a dozen water bottles from the fridge. She left the house behind and once she was far enough away she changed back to herself in a random alley way, though not before emptying out the maid's account of the money she owed for the forced prostitution of course. She swapped the maid's clothes for her own and two days later the maid's body was discovered.

The morning after Doppel-chan left no one bothered to go to the room and the parents called the school. They figured it would take a few days for their monster of a daughter to calm down and go back to her routine. However the next day there was still no response from the room and no sign of the maid Aiko. But when the head maid went to check on her she lifted the sheets, causing her to scream. Underneath them was a dead and naked Aiko with her tongue… cut off?

Needless to say once the police questioned them they found the insurance Aiko spoke of to the parents. With the actually files of their daughters quirk they also found a sound recording of their conversation. The parents and the rest of the staff were arrested, and naturally they informed Principal Nezu of UA. Whenever an out of control quirk case happened they usually consulted him. After they got the advice they needed from him, they headed out to find the girl full force.

MIDORIYA HOUSEHOLD (4 YEARS OLD)

A LITTTLE OVER TWO WEEKS BEFORE TOGA HOUSEHOLD INCIDENT

Izuku had woken up and his teeth were hurting, so he checked his look in the mirror. He had very sharp and pronounced canines, he was so excited he ran downstairs to his mother. "MOM! MOM! LOOK AT THESE!" Izuku screamed as he ran up to her showing off his teeth.

Inko was incredibly happy to see that her son quirk had finally awakened and going by those teeth it was some sort of hardening quirk, perhaps? That would definitely keep him safe if he became a hero, now his lack of a quirk was not a problem. "Play with the kids today and tomorrow we will go to the quirk doctor to get your quirk checked." She said ruffling his hair before serving him his breakfast. She had failed to notice the egg she served him had blood in it before he ate it. Oh well so long as he does not get a stomach ache then it should be fine but to call a bloody egg delicious? I guess it is true what they say, the happier you are the better everything tastes.

Izuku had been bullied for the past few months due to him not having a quirk, but with this they can no longer call him a freak, once he got to the park he showed off his teeth. They were giving him a slap on the back and congratulating him on this good news. Since they did not know what his quirk did yet they told him to just stand and watch as they played with a new kid today.

He was horrified when he saw them using their quirks to attack the new kid they mentioned before. Apparently they were quirk less and needed to know their place, at least according to the other kids. Without thinking about it, as if almost by instinct he bit the kid was about to use his fire quirk on their face. He shoved Izuku off and tried to attack him using his flames, but for some reason his quirk did not activate.

Before he knew it, the screaming from the other kid asking what he did began to fade. He felt hungry but in a different way than normal hunger, this like when he saw the bloody egg earlier. When he came too later he was in a hospital bed and strapped down for some reason. The doctors later told him that when his blood quirk fully awakened it was too much for him to handle. His quirk was apparently to nullify the quirk of anyones blood he ingested from them.

After a few days he was released from the hospital but all his classmates became scared of him. Some were afraid of their quirk being erased and others just thought he considered them a meal. His mother was socially isolated from everyone except aunt Mitsuki, her husband, and Kacchan. She ended up staying up late drinking since he first came home from the hospital, so he usually ended up skipping breakfast and made himself a sandwich for lunch.

Then one night after two whole weeks it happened again, he had not had any blood to drink since that day. Now the cravings are back he stumbled downstairs too ask his mom for help and he saw her drinking. She shouted something at him before throwing her glass bottle at him, cutting his forehead.

It had been not a blessing but a curse, she would have preferred her son to remain quirkless, but thanks to this blood quirk he was treated not as less than human like before, but like a monster. He was, he nearly drained those children dead and for all she knew, she was next. Everyone avoided her like the plague now, except for her childhood friend and her family. It was then she noticed Izuku had come down with that hungry look in his eyes again. "THWIS WAS ALL YOUR FWAULT YOU MONSTER!" she partly slurred as she threw the bottle in her hand at him. Inko was horrified at what she had just done to her baby boy, as he now had a large gash on his forehead. She tried to chase after him as he ran, but due to all she drank earlier, fell immediately and passed out from the fall.

Izuku was scared and ran before his mother could attack him again, both physically or verbally. She had called him a monster, his own mother, the one person he was supposed to rely on. Even after he heard her fall he continued to run out the front door crying and holding the wound on his head.

IN AN ALEY WAY IN MUSTAFU

Izuku had no idea where he was going but kept running until he could no longer move. His stomach was in pain from the hunger, and he had a headache from his head injury. Unable to move anymore he collapsed clutching his stomach as his fangs were also hurting quite a bit. As he collapsed he noticed a girl with blonde hair tied up in two messy buns approach him. This was when he noticed that she was looking at him with a sad look in her eyes. The next thing he knew she took out a thermos and brought it to his lips after noticing his fangs.

The liquid reminded him of the coppery taste he got from biting those bullies. After drinking it his hunger pains faded and he blacked out now unable to stay awake without them. When he came to later he was in an abandoned building of some sort wrapped in bandages on his head. There was a warm fire beside him that the blond girl from before was attending to.

Toga was going to a vending machine to get something to drink when she saw a child running her way. He was bleeding from a gash on his head and looked as though his stomach was in some sort of pain. He could not be no more than five years old, maybe even only four, he was a bit small after all. She could not help but feel saddened at the sight of another kid being abused, but she was on the run. She had to be smart, so maybe she should call the police so they can pick the kid up and bring him to a hospital.

Then suddenly he collapsed so she ran to his side to make sure he was still alive. When she turned him over she noticed his canines they were just like hers. That plus the pained stomach, does that mean he has a blood quirk? She quickly took out her thermos of blood of Aiko blood she had gotten just two days ago. The kid drank it and his pain looked like it was fading, so he definitely had a blood quirk. That was a relief, if she made a non blood quirk user drink blood things might have been worse for the kid.

After that he passed out. It seemed his hunger pains was the only thing keeping his head wound from knocking him out. She quickly put Aiko clothes to his head to stop the bleeding, then brought him to a nearby abandoned building she was sleeping in for the past two nights. With them away from random eyes she started a small fire and began to treat his wound. Fortunately it was shallow and did not require must attention, so there was no need to rush him to a hospital.

After that she just decided to stoke the fire and keep it burning, after removing his alcohol covered clothes and wiping him down of course. She then began to think about what to do, she cannot risk sending him back home. Otherwise his parents will just abuse him again, so should she take care of him? She looked to him and decided after meeting his eyes, she going to make up for her killing. Even if she had to continue to kill others to stay alive, she would do so for him and her. "My name is Himiko, do you want to come with me?" She asked hoping looking after him will make up for her sins. She went with the name Himiko because she did not want to use the name her parents gave her, and it was the first one to come to mind. She showed her fangs and the blood to get her point across they were similar to each other.

Izuku was just told her name and she offered to take care of him just like that, but why? She then showed him her fangs and the blood he drank earlier, so she was the same as him. He was hesitant to say the least, but she kind and possibly the only one to be understanding of his quirk right now. "My name is Izuku!" He said crying as he ran up to hug her, she responded back by hugging him. Being an only child he always wanted a sibling, even if it was on the first day of his life, he was happy to get a big sister.
