A betrayed mare

AN: the start of this story is inspired by one of my new favorite songs, which i have been listening to for over two hours on repeat

prologue

Izumi, a 14 year old girl, was in a chair, reading a story about two sisters. One sister was loved and adored by all, and her younger sister was hated and feared by those same people. As surprising as it would seem, her favorite character was the younger sister. As she read, she smiled. "I don't care what will happen, i love my sister," she said wistfully.

"Izumi, put that book away, dinner is ready," inko called out. "Alright, mother," izumi said. "I'll go wash up, first," izumi said, as she marked her place, put the book away, and went to the bathroom.

After she washed up, she looked in the mirror. She had bright green eyes, an adorable face, if kinda pale, and a head of emerald green curls that went to the base of her neck. "I look cute," izumi whispered to herself. The sound of a door opening sounded, and a feminine voice called out. "I'm home, izumi," the new voice said. Izumi immediately bolted to the source of the voice and glomped the newcomer. "Welcome home, sister," izumi breathed.

"Welcome home, akane. You have good timing, since dinner is just about done. Go wash up," inko said. "Alright, mother," said izumi's slightly older twin sister, akane. Akane's appearance looks identical to izumi's, except akane has a healthy normal skin tone. Akane gave her sister a squeeze, before she went to the bathroom to wash up, while izumi helped her mother set the table.

Once the family was at the table, they began eating. "I honestly hope my quirk comes in, soon," izumi said. "Who knows, perhaps our quirks will come in together?" akane said. "YEAH!" izumi cheered, her arms over her head.

Dinner after that was quiet, before the family of three went to bed.

And so, the next few years were like that. And the time came for the end of middle school.

Aldera middle, two years later

It was the end of the school day, and izumi was cornered by katsuki (again). After yelling at her, he was about to use his quirk on her, when akane appeared out of nowhere and punched his cheek, snarling at him. "What the hell are you doing to my baby sister?!" akane demanded.

Katsuki managed to get onto his feet, before he snarled at her. "Simple, bitch, i was teaching her her place: beneath my feet," he stated proudly. Akane was full of rage, as evidenced by her snarl and trembling. She suddenly grunted in pain as she bent forward.

"You ok, sis?" izumi asked. Instead of answering, akane yelled in pain and two large white alicorn wings ripped out of her back, nearly shredding her shirt to pieces, luckily she wore a bra, just in case her shirt tore. In addition to the wings, a light appeared halfway down on the side of her left thigh, appearing as a stylized sun, in a field of pink surrounding it and her green hair turned pink*.

After the wings and mark appeared, she panted in pain for a few moments, before she stood straight. "You want to go after my baby sister, you gotta go through me, jackass," izumi stated, as her wings spread. Katsuki scoffed, before he grabbed his bag and walked out. That bitch ain't worth my time," he stated, as he walked out.

Akane's wings folded, and she quickly embraced her sister. "Thank the sun that i got here in time," akane weeped. Izumi returned the hug, being careful of her sister's new wings. "Let's go home, sis," izumi said. Akane nodded. So, they gathered their things and went home.

Once the twins got home, they heard a familiar voice talking to their mother. They burst through the door and, without taking their shoes off, they ran to give their father a hug, and he caught them in a hug. After he put them on their feet, he noticed the new additions on his eldest. "Akane, when did you get wings?" their father asked.

"Izumi was about to be attacked by katsuki, again," she said. "Toshi, who's there?" inko asked from the kitchen. "Our girls, inko," their father, toshinori answered, before he looked at his eldest daughter. "Akane, how would you like it if i train you?" toshinori asked. Akane squealed and hugged her father tighter. "That a 'yes', akane?" he asked. "Yes, yes it is, daddy," akane said gleefully.

Izumi didn't look like it, but she was starting to hurt, as she felt that her sister was beginning to abandon her. She hung her head a bit, and went to her room and locked the door. She then went to her bed, laid down, grabbed her plushy and began to quietly cry, hugging her plushy to her chest.

Akane, too ecstatic to get personal teaching from her father, who is also the number one hero, didn't realize that her sister was hurting. Over the next nine months, izumi would try to talk to her sister, only for her older sister to brush her off.

Finally, about a week before the entrance exam for UA, akane had enough of izumi trying to distract her, so she slapped her little sister onto the floor, before walking away, while saying "don't bother me again, izumi," rather harshly.

Izumi laid there shocked that her sister hit her for the first time. After a few minutes, she managed to get to her feet and go to her room and locked her door. She looked around her room, and saw all the photos she had of her and her sister together, happy.

She picked up the knife that she had hidden in her room, and she started slashing the photos. Crying silently, she attacked the walls and everything in her room, destroying it all. After she finished, she was standing in the middle of her destroyed room, crying and full of hate.

Her mother tried calling for her to eat, but she shouted that she wasn't hungry. She hasn't left her room, except to go to the bathroom, and even that stopped, when there was nothing left to come out. She laid on her bed for two weeks, clutching her plushie and sobbing softly.

The day the acceptance letter arrived, izumi came out of her room. Sadly, no one noticed her, as her parents were focused on akane. So, she sat in the chair, and stayed there. Hours later, she heard the mail enter the mailbox, so she went to retrieve it.

Looking through it, she saw that it was mostly bills, but her sister's acceptance letter arrived. So she gave her mother the bills and put the acceptance letter in front of her sister, then she went back to the chair. As she listened to her sister turn on the hologram, it was revealed that she placed first in the entrance exam, and that she would be in class 1-A. "HAHAHA, i KNEW that i would be going to the best class in the best school in the world," akane said cheerfully. Not wanting to be around her family, anymore, she went into her room and mostly shut the door (she thought she closed it all the way), before she fell to her knees and started weep.

Wanting to tell her sister the good news, akane went to her sister's room. However, when she got outside the door, she heard weeping. Carefully opening the door, akane saw her sister on her knees in the middle of the room, weeping. "Sis?" akane asked nervously. Izumi snapped her attention to her sister, her eyes showing hate and pain, as well as her free-falling tears. "Leave me!" izumi ordered. "No, not until i say the good news," akane refused. Furious, izumi slammed the door shut, before she locked it.

Akane was surprised, and a bit sad, as she walked away. Behind the door, izumi was full of rage, pain and grief. "My dear sister came to rub it in my face," izumi thought. Izumi felt pain coming from her back, and she fell to her knees and curled into a ball. After a few moments, a pair of large alicorn wings that were such a deep blue that they were very nearly black ripped out of her back. Her hair turned as black as a starless night, as did her eyes. Finally, a stylized crescent moon appears halfway down the left side of her thigh, on a field of black*.

Izumi laid there on the floor, panting from the pain of her wings appearing. "Luckily i managed to contain the screams of pain," izumi thought, as she laid there. After about 10 minutes, she managed to get onto her feet. She stretched a wing and looked behind her at it. "That is a beautiful shade of black," izumi murmurs. Then, after folding her wings, she looks at the mark that appeared on her thigh. "A crescent moon," she said. She shook her head a bit and sat on her bed, carefully listening for her 'family' to go to sleep.

After a few minutes, she heard her 'family' snoring. So, she judged it safe to exit her room. Acting quickly, but silently, she grabbed some paper and a pen. Once she was back in her room, she quickly wrote a letter. Once the letter was finished, she packed a bag of clothes. She looked at the plushie on her semi-destroyed bed. "My 'sister' got me my plushie years ago, before our quirks came in. before she abandoned me," izumi thought as she picked up her plushie. "I'll take it, as the reminder of what we once held, of what she betrayed," izumi concluded, as she put the plushie in the bag. Quickly and quietly, she grabbed the cash that her 'mother' thought was in a clever spot. The amount of cash was a total of about 250,000 yen. "That should be enough to last at least a few days," izumi thought, as she went back into her room.

She quietly closed the door to her room, put a weight on the letter, to keep it from being blown away, put the yen in the bag and opened the window. "Good riddance," she said to herself, before she climbed out the window and took flight, away from the place that no longer felt like home. "How long until they find my letter, and realize that i'm gone?" izumi thought to herself, as she flew.

After flying for hours, izumi landed in a dark spot in the parking lot of a 24/7 store. She enters the store, looks at the directory and went to the bedding section. After searching for about 10 minutes, she found the comforter that she was trying to find: a princess luna and moon's comforter.

She paid for it (it was too large to sneak out), took to the sky as soon as she was in the shadows and entered an abandoned apartment building she saw. Once she was inside, she opened the package, unfurled the comforter, put it on and went to sleep.

Days later

Izumi was packing her comforter, when she heard an odd noise. She jumped to the left and avoided a slash. She quickly turned to the culprit, and saw that it was a cute girl with dirty blonde hair, messy buns on the sides of her head, sharp canines in a semi-crazy smile, yellowish iris and cat-like pupils. "Who are you?" izumi asked, while she took up a defensive posture.

The blonde smiled. "I'm himiko toga. You?" the girl, himiko, said, then asked. "Izumi," izumi said. "What are you doing in this apartment building?" himiko asked. "I ran from home," izumi stated.

Himiko looked surprised. "You too?" she asked. Izumi's eyebrow raised. "Why did you run?" izumi asked. "I need blood for my quirk, and to stay sane. My parent's did not like that, and denied me blood until i snapped and killed a person, before i drank their blood," himiko explained. "You?" himiko asked. "I deeply loved my twin sister. However, her quirk came in months ago, while mine did not. Our father offered to personally train her. As a result, my sister, who i loved more than life itself, actually hit me for the first time," izumi said, crying a bit and looking pissed. "It became clear to me, then, that she no longer cared for me. So i wrote a letter, packed a bag, stole our mother's hidden savings and ran. Luckily, my quirk came in earlier tonight, so i can cover more ground far more quickly," izumi finished.

Himiko looked shocked. "You wanna group up?" himiko asked. "Sure thing, himiko," izumi said. She put on her bag, dragged himiko to the roof and flew, carrying himiko. After flying for a while, she landed in a park, and put himiko on her feet. "Whoo," himiko said as she shook her head a bit, "that was a rush," she said, a hand to her head.

Just then, a man approached. "Afternoon, ladies. Might i have a moment of your time?" "we are not prostitutes," izumi bluntly stated. The man spluttered, before he collected himself. "My dear, rest assured, that is NOT why i approached," he said. "You may call me giran, and i am a recruiter, of sorts," the man, giran, introduced himself.
