The Kuroyami Family of Japan was a family shrouded in mystery that was known to be as old as Japan itself. As one of the most influential families in Japan, they enjoyed countless years of prosperity. Their children were known to be the best of the best: advisors to emperors, CEOs to companies, famous musicians, etc. Now, the structure of this particular family was a little different than others. For one, people never married out of the family, the outsiders always married into it. Also, unlike other families where the Head is always a male, the heir to the Kuroyami Family is always the first born child that shows the inherited skills of the family.
These inherited skills are what make this particular family so dangerous. What is the power that they have? This answer lies with the elements. Fire, Wind, Water, Earth. Since the time of the first Head Kuroyami Genosuke, the Head of the Kuroyami Family has always been able to control an element. The family was said to have been blessed by the elemental spirits when Genosuke selflessly agreed to perform a task for them. Where others failed, Genosuke succeeded and was handsomely rewarded. Being the first to receive the gift, he was able to use all four of the elements. His firstborn son, Kuroyami Keisuke, was gifted with the element of Wind and his second son, Kuroyami Kyousuke, was gifted with Water.
When both sons married and had children, it was noticed that the powers did not transfer to both families. For, only Keisuke's children received the next elemental gifts. As the years passed by, the tradition continued. Only the children of the current Head had powers and only the firstborn child became the Head. The other children, being less important in the eyes of the Family, were sometimes nothing but mere servants to their eldest sibling.
With the elemental powers, came the Kuroyami Family's own style of martial arts. Based on the attributes of the elements, the 4 forms of the elemental style of the Family became famous. Although all members knew some form of this style, only elemental users could bring out its full potential.
And with all the power that this one family received, they realized something important. Their family, no matter how much they tried can never have more than one person from each generation with the same element. For example, Kuroyami Haruka, the 6th Head of the Family, decided to have 6 children. She mistakenly thought that all 6 would receive elemental gifts. Haruka's own power was that of Water and her little brother had Earth. Her first through fourth children received the powers of Fire, Wind, Water, and Earth respectively. But, her 5th child did not receive the power of Fire like she expected. Thinking that it was the child's fault, she decided to have another baby. When that one did not receive any powers too, Haruka was devastated. Without power, her last two children were useless to her.
As her children became older, her last two became jealous of their power wielding siblings. Jealousy became bitterness and soon, fights started breaking out. And then, these two did the unspeakable and tried to kill their eldest brother. Enraged by their pettiness, Haruka executed her last two children and forbade anyone from speaking of them. It became an unspoken rule from then on that the Head should only have 4 children at most.
Now, keep in mind these facts as we talk about the current Kuroyami Family.
The current Head of the family is Kuroyami Kimiko, the firstborn daughter of the previous Head, Kuroyamo Kazuto. Kazuto died months ago, leaving behind 3 children and a pregnant wife. It was now that the family was anxiously awaiting the fourth child of the family to take over the missing Wind element.
So, it was a surprise when the doctor announced that two happy children were born instead of one. Kimiko, being the practical person she was, immediately demanded to know which child was born first. To which the doctor replied "The boy was born 2 minutes before the girl was."
With that said, Kimiko decided that until her new little brother showed his powers, nothing would be done with the twins. They were to be treated equally and taken cared of. After all, there has never been a case of twins being born to the Head before. For all she knew, the girl may receive the Wind power that would have normally gone to the boy. She had to wait until around age 6, when people usually used their powers for the first time.
As the Head, it fell upon Kimiko to decide the names of the two new additions to the family. So, on March 4th, Kuroyami Miki and Kuroyami Yukina were born.
The first 5 years of Yukina's life was as good as any child would want. She had all the food she needed, a place to sleep, and a loving albeit strict family. But, even as a child, she knew that many people favored her twin over her. It wasn't hard to miss. People always greeted him first when it was just the two of them. He got more presents than she did. He got more attention than she did. He even got to watch their siblings train occasionally when she wasn't allowed to.
Because no one ever wanted to do anything with her, the only thing she could do to entertain herself was read. The Kuroyami Family had always produced smart children and Yukina wasn't any different.
And then at age 6, suddenly everyone began treating her differently. Her siblings and mother never had any time for her anymore. The servants and other family members seemed to hate her. She eventually found out the reason when she overheard some people talking. Apparently, Miki used his power for the first time. Kimiko was trying to decide what to do with her now that it was known for a fact that she didn't have any powers. After all, a person without powers just wasn't worth the time of the Head Family.
The servants and other family members disliked her because even though she had no powers, she was still a part of the Head Family. They were just jealous. They didn't understand that being a part of the Head Family yet having no powers was a bad thing.
After hearing that her twin had obtained powers, Yukina was confused with her life. Why didn't she have any powers? She wanted answers. So, like any 6 year old genius would, she turned to books for answers. Not just any books, she turned to books that featured powers. At home, these books were well guarded and she wasn't allowed access. A trip to the library was needed. But, before she could go, she was called to a meeting with the Head.
Yukina fidgeted as she felt Kimiko's gaze land on her. "Why did you call me here Kimiko Nee-sama?" she politely asked. Manners were everything here.
"Yukina, I want you to follow me and watch you fellow siblings train today."
Now Yukina was confused. They never let her watch before, what made today so special? She understood after watching only for a few minutes.
"Do you see what they are doing Yukina? You understand that you will never be able to do the things that we can do. You will never be strong like us." Kimiko said in a cold voice.
"Hai, Nee-sama." the only thing that Yukina could do was agree. Kimiko was a strict person by nature and saying anything otherwise might make her mad.
"Yukina, you are more fortunate than the other members of our family because you were born to the Head Family. But, without powers, you cannot remain the same. When you turn 10, you will become a servant to your fellow siblings. That is my rule as the Head." Kimiko said before she walked away leaving a stunned Yukina behind.
To be honest, Yukina wasn't that surprised. She knew that something was going to happen to her. What did surprise her was that her sister actually thought that she would choose to be a servant to her siblings. Running away would have been a better option. Why couldn't she be taken in by a Branch Family?
The stunned girl made her way to the library easily. Nobody really cared where she went or how she was doing. The librarian mistook her questions about books on elemental powers as her wanting to read some fiction So, she was directed to the fictional section.
She sighed as she prepared to find the right section herself. She knew that elemental powers were not fiction and hoped that there were some books on them nearby. She picked up a random book to skim through and by chance of fate, she happened to pick up a martial arts based book, where she happened to read that a form of martial arts could result in the creation of Nen.
Somewhere in the universe, Fate smiled as she changed the life of another human for the better. Sure, she liked to mess with people now and then and give a few prophecies, but there are times when she feels like helping people. This particular case was a good example. This girl would have lived the rest of her life unwanted and shadowed by her own family. She would be treated no better than a servant and hurt many times by her twin brother's Wind powers. This family had been getting on her nerves lately. They were starting to think that they were Gods themselves with the way they flaunt their powers and the way they think everyone else is beneath them.
This young girl would be the perfect person to put them in their place. But first, she has to be able to measure up to them in terms of strength and powers. She knew the perfect place to send this girl to lean. A certain Hidden Continent would be great for her. Their elemental jutsus would do wonders in helping her. But alas, as strong as she is, even Fate could not break certain rules. This girl was not blessed by the 4 elemental spirits so she would not be able to use most Wind, Fire, Earth, or Water based jutsus. But, nobody said anything about her using Lightning based ones. Fate laughed as her plan was slowly coming together.
