When Quirks appeared, the normal human race was quickly outnumbered by 80% to 20%. It took time, but those dubbed 'Quirkless' came to accept those with 'Quirks'.

But, not everyone came to. Some born Quirkless into Quirk filled families, had the potential to come to hate those with powers. And where there is a spark of hate, there can also be an uncontrollable inferno of rage.

….

It was clear to everyone that Izumi Mizusawa was a happy child. Anyone who met the 4 year old immediately noticed her bright grin that always seemed to always be present. With loving parents and an older brother whom she adored, she simply had no reason to ever be sad.

With locks of gold and eyes bluer than the sky, Izumi was no stranger to compliments and praises. More often than not, people would think her Quirk was one of beauty but even she had no idea if she would even had a Quirk, both her parents were Quirkless afterall.

With her mother being a librarian, and her father an accomplished businessman, Izumi grew up around books and from that bloomed her love for literature.

However, hidden secrets and skeletons buried deep in the mind of both parents would rise sooner or later, and the outcome won't be pretty.

….

Izumi squealed in delight as she was chased around her bedroom by her older brother Hajime Mizusawa. The 12-year old scooped her up in his scrawny arms and twirled them around, flopping back down on the bed with an 'oof'.

"I got you now villain!"

"No fair Hajime!" The 5-year-old whined but wasn't upset, she shrieked in laughter as he began to tickle her sides.

"St-stop! I surrender hero!" She wheezed, out of breath from all the laughing.

"No can do Zuzu! A hero always takes the bad guys to jail!" He grinned through his crooked glasses and missing front tooth; having lost the tooth and bent the frames in a fist fight over some kids picking Izumi.

The walls of her bedroom shook, the sounds of something or someone being smashed against walls made Izumi jump and hold onto her brother, their playing halting. Hajime crawled off the bed and made his way to the closed door, opening it so they could listen downstairs. Izumi strained to hear what her parents were arguing about.

Arguments weren't common nor uncommon in her family. She had heard plenty of yelling before, but this seemed to be bigger than that. Her parents were screaming in with words she didn't fully understand.

Quirkless

Liar

Traitor

Fake

The words continued, words like 'Quirkless' confusing her. She half hoped that they were making up silly words as a way to stop fighting. Hajime crept out into the hall,

"Hajime what are you doing?" Izumi hissed, tugging on the blanket tied around his neck as his cape.

"I wanna see what's going on, they sound super mad. Remember it's a hero's job to help people feel better!" He whispered and crept down the stairs to the living room where the arguing was taking place. Izumi held her baby blanket close to her chest, nervous and scared.

Then the screaming started, it was her mother, screaming bloody murder. Izumi scrambled out from her room and down the hall into the towel closet, burying herself under the many folded towels with the blanket to hide. Screams echoed throughout the house and this time, Hajime was screaming as well. She heard her father shouting over them and the sounds of something or rather someone being thrown violently into the wall. Suddenly all sound ceased, two almost deafening thumps making Izumi start to cry.

She had clasped both hands over her mouth as she hid under the towels, she was a tiny child and didn't have to worry about sticking out. A chill ran down her spine as she heard her father call out her name in an almost sickeningly sweet voice. It wasn't like his normal voice, or his pretend voice used to scare the monster's out from under her bed. It seemed so much scarier and dangerous.

His heavy footfalls made their way up the stairs and into her room, throwing things around in an attempt to find her. Then he moved to the bathroom, then Hajime's room, then his room, and then the closet.

"Izumi, come here princess. Daddy wants to talk for a few minutes. Come out of hiding!" He cooed, his voice chilling her to her core, she let out a small whimper and that gave her away.

The closet door was almost torn off its hinges and made a dent in the wall as her father flung it open. He threw the towels down the hall and grabbed her by her arm and yanked her from her feeble hiding spot.

"Daddy stop! You're hurting me!" She cried and screamed as he brought her up close to his face. His blue eyes were wide and dilated, splashes of red mixing in with his blond hair and suntanned skin.

Izumi was begging now, begging for him to let her go, begging for her mom and brother to come save her.

"MOMMY! HAJIME!" She sobbed and cried out as her father threw her across the hardwood floor. They didn't come, they didn't even at a word.

"Shut up you damn brat." Her father snarled, Izumi managed to scramble to the bathroom and slam the door shut, her fingers slippery with the blood that smeared on her from her father's hands as she locked the door. The door frame shook as he threw his shoulder against it and she screamed as a knife pierced the wooden door.

"Daddy stop it!" She shrieked in fear as the knife stabbed through the door again and again. She heard his slightly maniacal voice through the shredded wood,

"You're one of them Izumi. You're one of them! One of those damned Quirk users! Your mother and Brother were too! She lied, she said she was Quirkless!" He was screaming now, completely hysterical.

"Daddy I don't-"

"You'll grow up to be just like them! Like those grandparents of yours, just like your mother! No…." the stabbing stopped and she saw his eye peek through one of the slits in the door.

"I won't allow that, I won't allow you to grow up at all! Yes that's it…. if you don't grow up then you won't have a Quirk!" He seemed to have forgotten that she didn't have a Quirk, she was 5 years old and still showed no signs.

"Daddy- Daddy I don't understand! What's happening? Where's Mommy?"

"Your mother is a liar! A traitor!" He screamed and threw his shoulder against the weakened door. It broke like paper and Izumi screamed at the glinting of the bloody knife in his hands.

As he brought the knife down, Izumi clenched her eyes closed and raised her hands above her head in a feeble attempt to stop the horrible weapon. But the pain never came, all that came was an explosion.

….

*before all the surgeries and stuff. All Might still has a limit but a lot longer than 3 hours*

"All Might!"

Said hero choked on air in surprise as his friend, Naomasa Tsukauchi burst through the door of the meeting he was in. When Toshinori Yagi turned, he blinked at the sight of the police detective. His face was red, lungs gasping for air, he must've sprinted to where he knew All Might was, the Hero just having been on television for defeating a villain and in a current meeting with other heroes.

"Detective Tsukauchi? To what do we owe the pleasure?" Pro Hero; Nezu, inquired. They were lucky to be inside a private office so Toshinori didn't have to strain his hero form.

"There's been a request for a hero in a small neighborhood a few minutes from here! There's been an accident."

"I'm not doubting you by any means, but wouldn't an accident be more suited to the police department?" Toshinori asked, already worn out from hitting his limit, he really didn't want to push himself.

"Normally yes, but this deals with murder. After some tests, we discovered that the victims were your brother and his family. I'm so sorry. But there was one survivor, a little 5-year-old girl."

….

"Izumi Mizusawa; 5-years-old, She is thought to be Quirkless." Tsukauchi explained and handed a photo to Toshinori. The much taller man took the photo, looking at the small child in the picture. She had golden blonde hair and vibrant blue eyes, a spitting image of her father.

Arriving outside the Mizusawa Household, Toshinori couldn't help but feel the cold out of despair in his stomach. The last time he had seen his brother Daichi; it had been less than pleasant, with Daichi saying he would see him next in Hell.

Poor Daichi had been born Quirkless; much like Toshinori. But that didn't stop Toshinori from fighting to achieve his dream. Daichi however, became bitter and cold to everyone who had Quirks. When Toshinori received One for All, Daichi distanced himself, changing his name legally when he was old enough and moving away. But Toshinori kept an eye on him for the first few years, he watched him get married and later heard he had two children, a boy and a girl.

Entering the household with Tsukauchi at his side, Toshinori was met with the sight of his sister-in-law and nephew's corpses lying on the carpet floor. Blood stained the ground around them and if Toshinori had to guess, they both died of stab wounds and or blood loss.

His sister-in-law; Aoi if he remembered correctly, looked as if she had massive bruising around her face and throat, almost as if she had her head thrown into the wall. Massive head sized and body sized holes in the surrounding walls confirmed this theory. He felt sick just looking at her. The Police directed him upstairs where Daichi was.

Unlike his sister-in-law and nephew, Daichi looked burned severely with his skin black and red. Blood spattered the walls of the hallway and the door was almost broken down, splinters of wood mixing in with the blood. Toshinori fought back a feeling of sickness in his throat, studying the scene until he left the scene and spotted his niece.

The tiny girl had an emergency blanket covering her shaking body as she cried into a paramedic in an ambulance. She had been cleaned of any blood or injuries before Toshinori had arrived and as he approached the two in the vehicle, the child looked up.

Her eyes were red and puffy, streaking her cheeks with tears. She had a second blanket clutched in her shaking hands, it was a soft orange color with rabbits on it.

"I'm Toshinori Yagi, her father was my brother."

"Alright, thank you for letting me know sir. She says she didn't do it, she says her father went crazy and tried to kill her so she fought back."

"How does a 5-year-old manage to kill a full grown man?" He didn't mean for it to come out as harsh as it did, it made the small girl flinch and huddle closer.

"We don't know, the investigation is still ongoing but you will be the first to know anything. Okay Izumi? I need to you go with this man okay?"

Young Izumi slowly looked up to Toshinori, her crystal blue eyes dilated and wide with fear.

"Why?" Toshinori kneeled down so he was eye to eye with the much smaller girl.

"I'm your uncle, I was the older brother to your father. As far as I know, you'll be staying with me." He said gently, trying to coax the girl into a state of relaxation which probably wouldn't happen any time soon. It took several minutes of coaxing before she was comfortable enough to get close enough to even touch him. She currently sat next to him on the ambulance and hid her face in the emergency blanket.

Authorities showed up and after hours and hours of paperwork, it was official. Toshinori Yagi would now be the legal guardian of Izumi Mizusawa.
