Welcome to my book! I hope you enjoy this take on the BNHA universe. The beginning is kind of...interesting and dark but I don't like super stories that are angsty the whole time so it does get light and humorous a lot...it is canon but canon-divergent on some stuff because a new character and keeping canon the whole time is boring! I'm always up for constrictive criticism, I've been doing heavy editing as well to fix some things, and if you catch something needing editing don't hesitate to let me know! Thank you again for reading and I really hope you like this!

One day long ago in Quig Quig, China, a luminescent baby was born with a unique power. Then, as time passed, the similar phenomena happened all over the world, and soon the majority of the population had obtained superhuman powers known as "quirks". Due to that, villainy went on the rise but that made room for people to pursue professions, like heroism, that used to only be possible in fiction.

***

At the top of a tall mountain hidden in the Rockies, November 12th, Tenshi Hikari, a woman with hair as white as snow and glowing purple eyes was giving birth for the first time. Her husband, Tenshi Akiko, a scarred and yet kind looking man with navy blue locks and large wings on his back stayed by her side letting her squeeze his hand as she grit her teeth in the pain of labor.

After 6 hours of pushing, a healthy baby girl emerged. The special doctors hired for this situation took the newborn away quickly and cleaned the blood and fluids from birth off of the child, the only sounds the baby made were whimpers and cries from the smack of her bottom to open her lungs. When she was clean and wrapped in a silky pink blanket, she was handed carefully back to her mother so they could have skin on skin contact.

"It's a baby girl. What's her name going to be?" The couple shared a look and replied together.

"[Name]." They stared down at their child in awe, she was a beautiful puffy blob of a baby. She was their baby, the one to continue on their lineage. She had purple eyes that were looking curiously to the blurry world around her.

On the top of her head she had the smallest tufts of curly bright blue hair. The most surprising feature was on the small girl's back. There were small wings protruding from her back and the tips of the tiny wings ended at her toes. Her parents watched in fascination as their child blinked her eyes a few times before getting too exhausted and falling asleep, nuzzling more into the warm bosom of her mother.

The doctors took the small [Name], giving her to be held by her father to allow Hikari to have her post-natal checkup as well as finish off little [Name]'s checkup as well.

Her large lung capacity was unusual but of no concern, it was said to be related to her mutated quirk. Papers were signed and birth certificates were made, although they are secret from the outside world, the new family of three finally was able to enjoy their new lives in peace.

There are 6 classifications of people in the quirk filled society: civilians (everyday people), police officers (people who weren't quite up to par with being a pro-hero), petty criminals (basically people who commit lame crimes just to do it), villains (the black and white bad guys who usually had 'scary' quirks-Yakuza included-), the pro heroes (the good guys with the hero licenses who fought against crime with their own quirks), the vigilantes (Heroes who went about heroics illegally), the mercenaries (people who killed for money). Your parents were part of the mercenary category. Mercenaries are people who kill for money (pretty much the same as a mercenary if you were being honest).

The good guys, the government who supports the pro hero's would hire mercenaries like your parents to get rid of bad guys without all the issues of trials, it keeps everything on the down low, and it keeps heroes (especially those who are in the spotlight a lot) from having to kill all the time. Villains also hire mercenaries like your parents to get rid of somebody they can't or so they don't get tied back to it. This is why families like yours were considered ancient, a way of life that stopped existing as the world grew and changed. Nobody wants to admit hiring an outside source to kill people for them. Lucky for you, you were born into a powerful family of assassins which means, the reason of your birth was to be an assassin.

You were 3 when you learned what your parent's did for a living. You were called from your room and with the awkward run that came from being a toddler, ran down the stairs to greet your parents at the door.

"Mama, Papa!" Your small voice cheered out as you jumped into your dads arms. He threw you effortlessly into the air and then caught you, nuzzling your noses together as you giggled and clapped your hands together.

"How's my sweet little angel?" Dad asked as he rested you against his hip, you giggled into his chest. You looked up, distracted by the door opening and revealing a scary, old version of mom and a scary looking old man. Small eyes looked at them in curiosity and they stared-no... glared-back. You didn't notice the stiffness of your father or the blank face of your mother as I asked:

"Who're them?" Mom turned her purple eyes to you, you thought she had a weird look on her face.

"They are my parents." You nodded and gave them a small wave, they didn't return it. You were confused though, you'd never met them, mom nor dad ever talked about them, them being here was weird. Without a word, the newly discovered grandparents turned around and walked away, your parents following. They moved swiftly and their footsteps made no sound, odd since yours made noise and you weighed basically nothing. After a walk through the dark building, you arrived at a big metal door. They touched a few buttons and after a bit, your hand was placed on a scanner. The doors opened and there was a room lined wall to wall in weapons like in the books your parents would read.

"[Name] today you learn the family business. We are assassins, I expect nothing but perfection from you. You disappoint us in any way, you will be punished." You held tighter onto my fathers shirt, fear and excitement filling your body. Dad placed his hand on your head and you relaxed instantly when he used his quirk to release chemicals from your brain to the rest of your body to forcefully calm down. He placed you on the floor between him and mom. You gave your grandparents a thumbs up and a loud shout.

"Yes!" That night, you witnessed your first kill. From that day forward, you trained. You learned to read and write and you were taught everything there is to know about being an Assassin. You had to know the basics before you could start training your body as well. You were isolated from the rest of the world, the only time you spent out of the house was to see an assassination happen.

You never felt bad for the people who died, that little twinge each time a life was gone was suppressed with the 'comfort' of your father. Being a child the true weight of what killing someone meant never crossed your path. You were taught nothing but the art of a kill, and any time you flinched away, your father made sure you feelings neutralized.

You soaked up knowledge like a sponge, children were easy to teach and you weren't an exception. You weren't anything prodigal but you weren't a slacker. By the time you turned 4, you could name over 50 ways to kill a person, how to silence your footsteps, and the rules of being an Assassin in the Tenshi family. You didn't learn things like normal kids your age did. You never learned about games that didn't involve tracking or battle, you had never even spoken to another person your age. You didn't even know what Dora was, but you could tell someone how to kill a man with little to no blood splatter.

When you didn't understand something or took to long to figure it out, you received a punishment in the form of a small jolt of electricity. It hurt, a lot and it made you work harder at learning what your family needed you to know. You also had to study languages. You could understand English, Japanese, and Spanish, speaking in simple yet understandable sentences like anyone else your age would. It was difficult and you took lots of punishment for messing up and forgetting words or mixing up languages when talking. Learning languages was important because your clients reigned mostly in those regions, Japan and America were the prime spots for heroes and villains so knowing the languages were a must.

You were about four for a month when your quirk developed fully. You had wings on your back like your father so you assumed you were going to have nothing more, but your mutation evolved. Having parents with dominant quirks and strong family genes made it possible for your quirk to develop into two parts, it was something they had worked for. Combining a physical with an emitter quirk had a higher chance of a dual quirk in the offspring.

You were enjoying your free morning by being with your parents. Your dad was helping you fly faster and longer. You were holding food in your hand but got a brush of wind so you accidentally dropped the calorie filled bar. You reached out to grab it, not wanting it to get the ground dirty. Your body tingled like there was a chill moving from your core outward and then the hand reaching outward glowed a bright white and what seemed to be a glowing piece of glass formed beneath the bar, catching it.

The surprise startled you and you forgot to keep yourself in the air and began plummeting to the earth, still staring in confusion at your hand. Your mother formed a large hand out of her ability to manipulate color and caught you before you crashed into the ground. Your father dropped beside you and held your hand in his.

"You're freezing!" You felt cold like you were in the ice pool again, your body was shivering and muscles were tense and ready to snap from the freezing temperature. Dad took off his jacket and put it around you. You kept your eyes on your hand, the veins were still glowing slightly against your skin. You raised your hand and showed it to your parents, unsure of screaming or being excited.

"Wha' is this?" My mom looked at my dad smugly.

"It's your quirk." You tilted my head in confusion but hesitated to ask anything in worry of being shocked, so she elaborated. "Your quirk is called Halo. It is a family quirk. You would either get color manipulation like mine, light formation like yours." She formed a dagger that shined of iridescent colors, you noticed how the bright green around you was now a dull grey. "Or you get darkness like what Grandmother has."

"I don' like it. 's cold." You pouted slightly, trying not to cry but your lower lip wobbled anyways. Your mother chuckled and your father smiled, placing a hand on your shoulder. You immediately felt a calm wash through your system.

"You seem to convert heat to light to allow you to manipulate light in its solid form similar to mine." Some of her words were confusing but you understood enough. Your eyes were glittering with wonder and amazement as she created colored animals for you to watch. You clapped, wanting to be able to do that someday too.

"Uwah! Pretty mommy." Dad ruffled your hair and mom held you to warm you back up.

The next day, physical training started. Assassins need to be quiet, fast, precise, and deadly. You need to be able to get in, get the kill, and get out without leaving a trace. Your body wasnt't the strongest, it never would be. You are too light and small for impressive strength but when you incorporate speed into attacking it would give you a chance to land multiple blows or a kill shot faster than if someone was just using strength.

You need to be able to wield weapons, be immune to toxins, fight, and defend yourslef quirk or not and that is what this training is going to be. Your family needs you to be the perfect assassin, you have to kill to make the world better like mom always said. There is no room for error, you have to be swift and perfect every time like dad says. If you failed the punishments would be worse each time.

The first part of training was exercise. You needed to make your muscles ready to fight, to be stronger so you can move fast and last longer. The stronger your muscles become, the better you will be. You ran. A lot. Every day you would have to run until you puke. Your little stubby legs stumbled often and you were awkward, still trying to figure out how to make all of your body parts function.

It felt like you were running forever and somehow going nowhere possibly because your legs were so small and so you couldn't cover much ground, the other part because it was not fun. You hated running. You liked flying but you were supposed to run. You were told to be fast on your feet as well as in the air and the more you in, the faster you get.

When you were unable to keep your form good in training or didn't meet the standards set—which was often in the beginning because your body just wouldn't work sometimes— you were forced to take a small dose of common poisons to build up a slight immunity to what would be considered regular doses. They made your tummy hurt and those nights you would go to sleep with your parents because the poisons would make you sick.

Before and after every training session you would stretch. To go along with speed, you needed to have agility and flexibility. Dad helped with that a lot, he moves more agile than mom. Mom is a heavy hitter and dad is light and fast like you were training to be.

Your favorite training was flight training. Your body was built similar to that of a bird so flying would grow to be as natural as breathing. Your wings protruded alongside each part of your upper spine, right beside the bones of your shoulders. They were large and reached down to right above the bottoms of your feet. Your wingspan when stretched out fully, was no more than double your height. Your wings were pretty strong too, they can deal and take blows as well if not slightly better than the rest of your growing body. Your bones, just like that of a bird, were hollow but they were stronger than regular bones, being able to bend more so they were harder to break. Your body was built to be light in order for your wings to be able to carry your weight.

Your lungs take up more room than a normal person and process the intake of air slightly different. They take in more oxygen from the air around me and have a greater capacity as well as needing less pure air to breathe. They function like that because you are made to withstand high altitudes and speeds that a normal person's lungs wouldn't be able to handle. To properly sustain your body, you needed triple the caloric intake of a regular person, birds got their nutrients from bugs and plants but you got yours from whatever you could eat.

Training for manipulating light was the worst, you failed every. single. time. Failing at controlling this quirk made you receive punishment every time you practiced with it. You were switched to electrical therapy to hopefully push you to use it and it hurt. Having the blue lightning forced into your body hurt bad but you had it happen so often, it would take more and more each time to do more than cause your muscles to spaz and lock down. Granted if you were hit with something the equivalent of a taser it would still knock you out, something your grandparents were planning on changing in the next few years.

You trained with weaponry sometimes, your Grandmother was a master so she had you go through weapons and their uses. With the new age of quirks though, ancient weapons like swords and the like were less and less used.

There were training dummies you used to practice fatal hits Your accuracy with a knife was your specialty. When grandma saw your skills with knives, instead of punishment they bought your own set. They are silver and sharp, light and balanced for throwing, and have purple handles. The blades are kukuri pointed which makes them good for throwing and great for slashing. You could feel the balance of a knife when in your grip, the trajectory for a kill is calculated almost instantly with your muscle memory and your body moves accordingly.

Combat training was one a week after you learned how to make your body respond when you needed it to do something. Perhaps with age came a better control over motor functions. Your grandfather was in charge of combat training...he was brutal to say the least. No matter what, no matter the years you worked you never came close to landing a critical hit on him, even when he held back. After each session with him, you would have more bruises than clear skin and you were pretty sure you had internal bleeding once or twice.

Your Grandpa had you train to land combo attacks in a quick succession so that even if your damage of one hit didn't have the greatest damage, multiple of them can become equivalent to one large hit. It was difficult, your small body didn't have a long reach and even when you got faster and faster, your grandfather was always 3 steps ahead without even having to use his quirk.

"That was weak. Again." His gruff voice echoed in the training room drowning out the sound of your panting. You pushed up and off the smooth cement floor and ran at Grandpa, fists raised and body low and ready to strike. You feinted with a left jab and when he blocked, you went in for a right hook. He saw it coming and grabbed your hand. You arched my back to go upside down, putting your left hand on the ground to get enough leverage to push off and aim a kick at his chin.

When your hand reached the ground and your foot was raised, he kicked your hand out from under you and used an open palm strike to your chest, sending you tumbling to the floor once again. You bit your tongue from crying out in pain, it was a sign of weakness and you were not going to be weak.

"That was a fucking disgrace. Again."

"You're so damn weak. Again."

"Put more power into your hits. Again."

"You're supposed to be fast. Again."

"Pick yourself up and wipe off your blood. Again."

"You're supposed to become a master assassin, hit like one. Again." His calculating dark purple eyes watched as you attacked him over and over again to only be sent flying back. You never talked back to him during training, he was cold and harsh but you loved him. He was being like a good Grandfather and helping you to be strong.

The next few years you spent honing your skills into a finely tuned assassin for the Tenshi family. You spent no time with others your age, you didn't know anything of the outside world except geographic locations and important areas within specific places. You wore all black for the most part, grandma picked out your clothes and it was always clothing fit for training. You kept your blue hair to your shoulders and pinned your bangs back with a bow mom and dad gave you for your birthday once.

You have only seen yourself in a mirror a few times since you started training. Your eyes were striking purple like your mom but you had more features from your dad. Your cheeks were pudgy with child fat and your skin was darker than moms. Maybe it was from the bruises you sported but you were never sure.

I'm small.

If the medical books were correct you should have been taller but possibly because of your body structure and how you didn't aways get the calories you needed you were kind of small. You received punishment often for speaking incorrectly, failing in a training exercise, or getting something wrong. Your parents over time stayed with you less and you were alone more and more. It didn't matter though, all you did was train until the family decided you were ready to make your first kill. Kill or be killed, there was nothing else to it.

A/N Hey guys chapter 1! Tell me what you think so far about yourself! youre going to meet a few of the characters soon and I'm excited! The character seems bland right now but I assure you she will gain a personality, it will make sense on why she acts this was in the next few chapters. It definitely won't be a villain story so if you think it will...you're wrong. I'm going to do my best to not make a mary sue or anything, i want development and fun and stuff in this fic! Enjoy.
