Warning! This fanfic is a bit of an AU.

DISCLAIMER: I don't own Akatsuki no Yona.

I am a dragon; a species that rival God in rank. Dragons, after all are considered to be great deities that represented several noble traits such strength, courage and wisdom or even materialistic stuff like wealth and power.

Most of my brothers are examples of that. My family is the so-called Heavenly Dragons that live in the sky. The family consists of six members; five older brothers and me, the youngest. The oldest four are Hakuryuu (white), who possesses great strength and can destroy anything in his path; Seiryuu (Blue), who can see anything from great distances to a person's soul, literally; Ryokuryuu (Green), who can jump high enough to reach the stars and moon and touch them and Ouryuu (yellow), who has a steel-like indestructible body that is impossible to pierce.

Like I stated before, I said most, not all of my brothers; Akairyuu (red), the fifth brother, was born before me. Although born with beautiful fiery red scales that made the many other beings of Heaven burnt with envy, he was not blessed with any special abilities like our mighty brothers to call his own. Yet he was kind and gentle; compassionate to any living creature he met. Thus, he was not very well known among the humans due to not meeting the expectations of what qualities dragons should possess, as perceived by the humans.

Lastly, there is me, the abomination of the Draconic bloodline. There are a few factors that set me apart from the other Dragons. To start, I am the only female, which is strange as Dragons are usually born with the Yang energy. Due to my gender, I am only half the length of each of my brothers. But that is the least of my worries. Next, I was born as Kokuryuu (black). I am as dark as midnight and black as a raven. Even so, it wasn't just my natural complexion that puts many off…. it is the special ability that I was blessed or rather cursed with. I was not given a physical trait like my four brothers. Instead, I received my "gift" as part of my personality. You see… There is a side of me that is heartless, dark and calculative. Here are some examples: I can easily make accurate analysis of a person's character and anticipate his/her thinking and actions. Excelling at deception, I can completely deceive people and manipulate them into doing my bidding through using carefully chosen words and sweet talk. There are many other things I could tell you, but in short, I am a natural mastermind.

I could be considered wise if put in nicer terms. However, the residents of the earth viewed my gender, color and talents as evil and bad luck. For that reason, my name was banned and shunned in all temples and shrines and was forbidden to be spoken of. Occasionally, some secret occults or greedy men would pray and worship me as their patron god. I usually ignore their prayers though. As sly as I was, I was not evil and cruel. In addition, since I was living in heaven, I had no need for my abilities.

Nonetheless, the dragons loved Akairyuu and me dearly despite our flaws and vice versa. We all live in bliss in our paradise for many, many years.

Since Akairyuu and I were the closest in age, we mostly our time together, inseparable. We would frolic, chat or just spend time in each other's company. Akairyuu was especially fascinated with the humans. He would usually peak down at the earth from the heavens. Being a good little sister, I would just follow suite. Akairyuu would gaze at the humans as they did their business for hours in wonder. Truthfully, I could not understand what he saw them and tried my best not to doze off whenever we watched these simple beings. There were times that I wanted to complain how dull our 'little' activity was; yet whenever I look up I could see Akairyuu's eyes shinning and my mouth would immediately snap shut. This had continued for many decades. Akairyuu's interests in the mortals never wavered. He had even given himself and me human names. He had also tried to give names to our brothers, however they scoffed at the idea, believing that they were too high and mighty to have one.

One day, a huge war erupted down on earth that led to millions of tragic deaths. By then, most humans had lost their faith in God and any other deities, which included the dragons. Akairyuu, being the compassionate dragon he was, feared for all of their lives and finally made a decision that would change our lives forever. He had decided to descend from the heavens and take on a human form in order to end the endless fight. Naturally, all of us were against the idea.

My dragon brothers tried various ways to persuade Akairyuu to abandon his plan. As the sibling closest to him, I understood that Akairyuu would stick to his resolve no matter what and never joined my brothers in their endeavors. Their actions were futile as I had predicted and Akairyuu descended from the heavens anyway.

So, we watched Akairyuu's moves and actions closely day and night after Akairyuu's arrival on earth. Eventually, Akairyuu was captured, tortured and soon to be executed when the dragons finally had enough and descended from the heavens to save him. Once again, they pleaded Akairyuu to return with them to heaven and offered to annihilate the humans as punishment only to be disappointed by Akairyuu's rejection due to his love for the humans. And much to everyone's shock, we had also learnt that he had forfeited all his privileges as a dragon, which included his immortality. In short, my fifth sibling had become completely human, and could not return to heaven anymore.

Therefore, in order to protect him, the dragons gave their blood to four chosen humans, which granted each one of them the special abilities of the dragons respectively. They were to be Akairyuu's companions and retainers, and would serve him for the rest of their lives.

Unlike my older brothers, I did not choose a human to be on my behalf as my power was a mental ability, which might taint the person with darkness if they were not strong enough to resist. On top of that, having a person granted with my power among Akairyuu's companions would disgrace my beloved kin and his crew.

Nevertheless, I too wanted to help Akairyu and ultimately decided to descend from the heavens and take on a human form to watch over him and his new servants. Obviously Akairyuu did not know about it as he was no longer associated with us and my brothers opposed my decision. It took a lot of reassuring and promises such as not forsaking my draconic heritage like our now red-haired mortal brother to be allowed to appear on earth.

When I touched down upon the unfamiliar earth, my jet-black dragon body morphed itself into a female human body. My skin was sun-kissed brown and my new raven-black hair was straight and reached my bottom. When I looked into a nearby pond, I could see a pair of sparkling purple eyes; similar to Akairyuu's, or the human name he now went by Hiryuu's eyes staring back at me. The lips of the young girl staring at me were plumb and red. She looked only about fourteen or fifteen, and will remain so for the next hundred or thousand years if she retained her immortality on earth. By human definition, I was supposedly attractive and alluring.

As expected, with his new companions by his side, Hiryuu was eventually able to put an end to the bloodshed. Under his leadership, a great kingdom called Kouka rose, with him as its king. However, it never entered an era of peace and harmony, and was in constant threat. Thankfully, the four dragon warriors were there to protect it. There were even a few instances where I even joined in some fights when the dragon warriors were losing to the opposing armies secretly, and of course in the darkness.

For the first few years, I resided in the capital Kuuto and kept a low profile. In the cover of night, I would sneak into the palace by scaling the walls with my claws and ran on the rooftops while clad in black clothing from head to toe. Since I was still a dragon, I could morph my human body back to my original form or any part of it at any time I wanted. Of course, none of my dragon features were as great as those of my brothers' specialties respectively. My five senses were also much sharper than a human's, naturally, and allowed me to sense any incoming danger from afar.

I would watch my brother as he either worked alone or be with his subjects but never once dared to approach him. After all, I did promise our brothers that I would only watch over him. His live evolved before my eyes. I could tell he never regretted his decision.

Soon, he found love, and from the love he shared with his new human lover bore them a son; a heir. I was interested in the child and would visit him whenever he was alone in his crib, only leaving when I felt the presence of a servant arriving. The child unfortunately did not inherit his father's red hair but was adorable nonetheless. I visited him each night without fail since his birth until he was able to speak his first word. I will admit there were times where I was careless enough to get carried away playing with my nephew and went against my senses as sometimes a servant girl would walk in on us having a bonding time. I would always dart out of the room in less than second when that happened. It happened the same to his younger daughter as well. I must have scared the maids senseless; at best they probably saw a black mass flying pass them. Ridiculous rumors circulated around the palace afterwards about how a shadow haunted the prince but died down unexpectedly quickly. I wondered why back then. I did have a sinking suspicion but I tried not to think about it.

I left the capital about a decade later, knowing that my brother was in good hands and decided to explore the vast land of the kingdom to quell my curiosity of the foreign place. I would move from village to village, never staying at one for more than two years to avoid suspicions. I would normally return to the palace at least twice a month to check on my brother and his newfound family.

Several decades later, word in the villages I was at claimed that Hiryuu was on his deathbed. Right after I heard the rumor, I headed for Kuuto.

Just like before, I slipped into the royal residence through utilizing my regular methods. I situated myself right above the King's chambers. Several presences came and go; most being the dragon warriors', the royal families', the ministers' and some maids'. Many hours passed by. I waited patiently, never once moving, only shifting my weight once in a while in case my movement gave me away.

Finally, only Ouryuu remained in the room. I could hear a faint conversation from below me, full of emotion. As soon as I felt Ouryuu's presence leave, I hopped into the room through the window and landed gracefully and softly on my feet.

The bedchamber was simple but elegant. Polished wooden cabinets and wardrobes aligned the walls that were engraved with drawings of the five dragons. No drawings of me, as usual. At the center of the room was a huge silvery white marble table and accompanying it was a gleaming golden chair. And right behind the pair was a king-sized bed where my brother laid in white covers. Even from afar, I could see his pale white complexion and the slight wrinkles snaking down his face and arms. His once blazing red hair has lost its shine and lay limp around him. I cringed a little at the sight before me. His eyes were closed, like he was sleeping. But I knew better.

"You're dying, Akairyuu. Or as the humans call you now, Hiryuu."I stated monotonously from a corner of the room.

His eyes flickered open right away and turned toward me as I approached him. "You do not have to state the obvious, sister." He gave off a throaty laugh as I stood by his bedside.

"This is the first time I have ever seen you in human form. I must say… You look so beautiful. And very young at that."

"Stop with the jokes. What are you going to do now? You are leaving everyone behind. Your warriors, your wife, your children…and me." My voice trembled slightly, surprising me.

"I'm sorry." His eyes fluttered close once again.

"That's what you get for becoming human. You knew the consequences yet you went ahead with it." I realized that my resentment bottled inside from over the years was finally released.

"Did you come here just to lecture me?" Once again he was looking at me.

I shook my head. "Lecture or not, it will not change anything. Once you are gone, I will return to the heavens. Just like old times. Except this time, there's no you anymore." My eyes suddenly felt swollen and watery. I blinked several times to prevent anything from leaking out.

"I' m sorry. I never realized…." His hands, which reached out and enveloped mine, albeit shakily, felt fragile and papery. "You know, I always knew that you were around me."

My eyes widened. "What? But I concealed my presence from the other dragons! And you are fully human now! That's no way any of you could possibly sense-"

"We have been together for a long time, how could our bond ever be broken so easily? I had the feeling that you were always around me. When I heard of the 'shadow' that lingered in the battlefields and apparently haunted my children back then; I knew. It confirmed my suspicions." He smiled at me. "Even if you change wholly, whether looks or personality, I will always recognized you, my dear sister." At that point, tears uncontrollably spilled from eyes and down my chin. I clutched his hands tightly, frightened of letting go.

"Listen," Hiryuu coughed a little. "I know that I will be leaving soon. But I will return." He said with such certainty that I almost believed him.

"Will you stop fooling aro-"

"I meant it. I will return to your side one day. And when that happens, I would like to see my Dragon Warrior again."

"Wait!" I realized what he meant. "No you couldn't possibly…Why would you?!"

"I really want to see them when I return."

I gave off a humorless and sad laughter. "You are willing to let Ouryuu wander alone for many years? And you want me to continue the bloodline of the other three dragons'? You do understand that each dragon will live a short live, right? And all for your own sake?!"

"Yes." I stared at him in horror. The brother that I knew was always selfless. This was the most selfish and cruelest thing that Hiryuu had ever said or asked.

"You want me to continue the bloodline of Hakuryuu, Seiryuu, and Ryokuryuu and while at that make me continue to stay on earth for who knows how long? This is the most selfish thing that you have ever asked of me, brother." I echoed my thoughts.

"I can't help it. I am human now. Please."

I felt like shouting at him and protesting that he wasn't, but I couldn't. I just let out a sigh of resignation. "I give in."

"Thank you…. I know that this is the hardest request I have ever asked of you. One day I will come back and see you all. And in return, you will help me reunite with my warriors again."

"Yes."

"Thank you. Thank you so much. I love you, Shi…" He never did finish saying the name that he gave me in our childhood.

A torrent of tears poured down my face and I released a loud sob. "And you are loved too, brother. You are loved so, so, so dearly." I leaned down and pressed a tender kiss on his creased forehead. I left soon after.

His death was announced the next day and the kingdom entered national mourning. All around me were soldiers and peasants alike crying their hearts out like the world had ended.

I was the last person to see him.

Eons and centuries went by after that fateful day. Truthfully, I lost count after a century or two. Days went by in a blur, and suddenly in a blink of an eye it would be a whole new year and then another.

I still wandered around as usual. Sometimes I would revisit the villages that I had once resided in and meet my human friends' descendants. It was very bittersweet; it was like meeting my friends all over again when I first landed on earth and overwhelmed me in nostalgia.

Other than that, I honed my skills in combat, both in close and far encounter, armed or unarmed till I was able to take down numerous burly men much bigger than me without the use of my dragon features at all. My five senses came in handy as well and aided me in many fights.

Most importantly, my ability was put to full use over the years. Since there were still countless numbers of nations wanting to conquer Kouka or just some disgusting greedy men who wanted to take over the throne, I chose to become a freelance assassin to help get rid of any threats. The job was very easy; well in my opinion it was. To be honest, it was more like a fun hobby. I would disguise myself and get close to my targets using various means, then finish the job once their guard was let down. It could be from just simply poisoning their meals to brutally swinging a knife into their bodies while they screamed as their blood splattered the walls. And when I was feeling like it I would make enemies turn against each other and all for absurd reasons. I swear they were all just putty in my hands. I guess that was the part of me that was dark, and still is.

So I kept on fighting, kept on wandering and continued waiting on and on for hundreds of years until the day came when the sky was awash in a blanket of scarlet redness.

I could feel the familiar comforting aura of my long gone sibling tingling in my very soul and wondered if Ouryuu, who was a traveller like me and the other three current dragon warriors could feel the same magnificent feeling that I felt.

I smiled as I looked up from the forest I was resting in. "And so it begins."

AN: I had to get this idea off my chest for a long time. And that was wondering if there was a fifth dragon. I mean it kept haunting me whenever I was studying for my exams and since they are over, I can finally write it, yay!

That being said, I'm not exactly sure I will continue this fanfic. The first chapter was merely a…. draft? A test run? Wha….. There are obviously also some errors too….I mean I had to Google the names for black dragon and red dragon, I'm not even sure if they are correct.

Well I hope you had a great time reading The Fifth. See you next time. (Probably)

P.S. If you must know, the whole continuing the bloodline of the three dragons thing is actually relevant to the plot.

Bye
