Night time in a region in Japan where the secret location of a village is there where the people are enjoying the night with friends, families, or dating in this case.

There is someone walking by a young boy about ten years old with black hair color and black eyes wearing a simple black shirt with red flames designed and has a Japanese symbol meaning black dragon on it, also wearing short gray sport pants and red sport shoes.

This young man is (y/n) ryushin, and he's well known in the village cause his father is the leader and his mother commander of the military here.

The village prosper for so many years and said that millions of years ago, his ancestors were great warriors to protect their homeland from evil tyrants who want the secrets they possess, but all have failed so many years and the people moved into hiding since those years.

Reason of it cause legends said that a dragon fell here and a person try to save it but the great dragon died from its injuries but despite the person who tried to help so it granted that person its blessing to possess the capability of a dragon such as strength, stamina, and healing.

Those years have been kept sacred, and the ancient family was born as the ryushin clan who were the protectors of the village.

Until something happened, beings from other planets came to invade and cause destruction. They're called savages attacked many city's and killed innocent lives, which took great military attack to destroy them.

However, they kept coming to attack the planet, which the solution to united the nations to face this threat and from the meteorites that came from the savages are called variable stones and created them a crystal weapon known as hundred.

Through that, the slayers have been born through the aptitude test.

This led his home village to join this battle, protecting the world from the monsters and destroying them all.

Since then, everything has been at peace so far.

(Y/N) arrived at his home to see two adults talking, which made him smile to see his parents.

Y/N: Hey mom, dad. Said with a smile.

This gained their attention and smiled at him.

The woman (m/n) ryushin has long black hair and eyes, wearing a commander uniform, while his father (f/n) ryushin wear a special cloak that signify as leader of the village.

His mother hugged her son.

M/N: Hello, sweet heart, did you enjoy your usual walk. Said with a smile.

He nodded to them.

Both parents knew that their son is very special, his academic is great, training so well, and surprisingly, his aptitude test is higher than anyone out there.

They decided to keep this a secret, knowing full well that would lead to something bad but want their son to enjoy his childhood life before deciding what to do.

F/N: Why not go to your room and rest up, we have work tomorrow, kiddo. Said with a smile.

He nodded and headed inside the house.

Later.

(Y/N) came into his room after taking his shower and wearing short gray sleep pants and was about to wear his shirt.

Until he hears a beep sound and turns his head to see his computer, meaning someone calling and making him smile, knowing who it is.

Once he presses the answer button on the screen, suddenly an image of a young girl that looks the same age as him with blonde hair and blue eyes.

The girl is Claire harvey, his childhood friend.

Y/N: Hey Claire, how are you doing. Said with a smile.

She smiled at him while a pink blush on her cheeks.

The two of them have been great friends since the first meeting, where his parents decided to take him to do some business with warslan.

There, he met Claire, face to face, getting along quite well together and learned a lot in common.

Especially they developed feelings to each other since then like love at first sight.

Claire: I'm doing good, (y/n) I heard you're gonna take the aptitude test if you're compatible for a hundred. Said with a smile with a pink blush on her cheeks.

This made him chuckled a bit, seeing she's excited since she did her test, and he will soon take it meaning training together.

Y/N: That depends on how it goes, claire. Said with a smile.

She sighed, knowing he's right about that there were some that didn't meet the expectations of the test.

But then suddenly (y/n) hears a syren alarm system, which his eyes widen knowing one thing.

Claire noticed his reaction and heard the alarm on her end.

Claire: (Y/N) What's going on?. said with a concern look.

Suddenly, an explosion has been heard, and he looks at the window, which to his shock and concern to see savages attacking his home.

Y/N: Savages are attacking my home. Said with a concern look.

Claire widened her eyes in concern and fear.

Claire: I'll contact my brother to send help. Said with a concern look.

Y/N: It may be too late, Claire. I gotta go. Said with a concern look.

Claire is concerned for him and nods.

Claire: Please be careful. Said with a concern look.

He nodded with a smile.

Y/N: I will be fi-. Before he could finish his sentence.

Suddenly, an explosion happened to his room, which sent him crashing to a wall.

Claire saw that and was about to shout, but the computer got crushed.

Getting back up hurt as his forehead bleeding and seeing that a savage passing by destroying the village.

Suddenly, it got destroyed by his parents.

They noticed him and rushed to check for injuries, but he's ok.

M/N: Thank the great dragon you're alright. Said with a worried look.

Then they hear a roar and look to see more of them walking by.

Knowing they're far too many and can't handle it.

(F/N) thought of something and then looked at the mountain peak, which is where something sacred is there and is the most important place to protect for generations to come.

Then he stood his ground, drawing his weapon.

F/N: Take our son to the sacred temple, and don't stop. Said with a serious look.

That got his wife's attention knowing what he's talking about.

M/N: My love, I don't want to leave you alone. Said with a concern look.

He looks at her with a smile. 

F/N: Go and take our son to safety. I will be right behind, I promise. Said with a smile.

This made her feel saddened but nodded, knowing they must protect their child whatever means even sacrifice their lives.

She quickly grabbed him and ran to the mountains, but (y/n) tried to reach his father, but his mother won't let him go despite him screaming for his father.

The man himself is looking at the monsters before him at what he received. The intel was true about the savages motives.

F/N: So you're here to destroy the ones who have the power to rival you all, well you won't get the chance. Said with a serious look.

This his eyes turn Crimson red with a black slit with a red aura around him.

F/N: Because you will all fall by the might of the ryushin clan. Said with a serious look.

Then he charges at them head on.

Meanwhile, (y/n) still carried by his mother, who is running to the mountain.

Y/N: Mom, we can't leave dad face them alone. Said with a worried look and tears in his eyes.

She didn't say anything and continued running to the mountain, which made (y/n) saddened.

Then they hear an explosion and (y/n) see where it comes from but then see a dragon like aura attack that roars in the skies and then disappeared.

This (y/n) widened his eyes in complete shock and despair because that is one of his fathers techniques unleashed.

Looking down in sadness and tears in his eyes, knowing what has happened to him, especially his mother, who's tears falling down as well.

She is almost at the mountain path to the temple.

But suddenly, a beam attack hit in front of her, and then an explosion happened, sended her flying and accidentally letting go of her son.

The two of them crash to the ground hard.

(M/N) quickly stand back up and see the savages catching up to them.

(Y/N) getting back up and holding his right shoulder feeling the pain of the fall, meaning it got dislocated.

Then, he noticed his mother standing back up and aiming her weapons at the approaching savages.

Y/N: MOM!!!. Yelled with a concern look.

M/N: GET TO THE TEMPLE NOW!!!. Yelled with a serious look.

He hesitates and goes back to his feet.

Y/N: I WONT LEAVE YOU, PLEASE WE CAN GO TOGETHER AND REACH IT!!!. Yelled with a concern look.

But his eyes widen in complete shock in fear to see the injuries his mother had on her right side of her stomach being pierced by a debri.

She looks at her son with a smile despite the pain she's in.

M/N: Run son, run, and when the time comes, fight to live. Said with a smile and tears in her eyes.

Despite this, she will be saddened not to see her son grow up to be a good man and someday have a nice wife and have children of their own for her to spoil knowing full well that he has been developing feelings for claire.

She then looked at the monsters as her eyes turned Crimson with a black slit, and then she fired her energy cannon at them.

Seeing he can't argue with her and tears falling down and quickly runs to the mountain.

Tears won't stop hearing the explosions in the distance the farther he goes.

When he reached the mountainside, he saw a stone door embedded there and had drawings of dragons in it and then some dragon statues beside the gate.

He quickly pushes the stone gate to open to enter and quickly close it.

But knowing it won't hold and quickly to find a place to hide for now.

Once reached the center of the temple, he's awed to see in front of him.

It is a huge cavern, but at the center of it is a bones of a dragon judging its position is like it died with its injuries and sleep in peace.

Hearing about the stories of his ancestors was true after all and saw this site before him.

But it was short-lived when an explosion broke through the entrance breaking through and (y/n) evaded the stone debris.

Once he sees the dust, the cloud clears his fears, getting the better of him seeing more savages entering the temple.

He walks backward, not knowing that he's walking to the dragon skeleton.

Doesn't know what to do as the monsters are close and prepared their attacks once they open their mouths.

Seeing his life flash before his eyes of his life with his family and friends in the village.

But the most important part is Claire, who he met once when she was saddened of what happened to her younger sister and can't help herself to blame for not being strong.

That fateful day, he promised her that they would fight side by side to beat the savages and get stronger together.

That is when something inside him snaps as he opens his eyes, showing the same Crimson color as black slit as his parents have.

Y/N: LIKE HELL I WOULD DIE HERE!!!. Yelled with a determined look.

He quickly charged at the monsters full speed, but unknown to him, the dragon skeleton eyes started to glow crimson red with a crimson red aura flare around its body.

Then suddenly, a beam of energy shoots from its mouth and hits (y/n) full force.

But it wasn't an attack at all it was something else entirely.

Which then, within the light, a beam of energy fired at the savages full force disintegrated to dust along with others.

Leading the energy beam hit outside of the mountain and hit the remaining savages that were heading there.

Once the attack ended, the light vanished revealed (y/n) in some kind of armor of the black dragon.

He looks at himself and feeling the power surging within him, and can't understand what's going on.

Until he hears a growling behind him with made him nervous.

He turns around only to he shocked to see the dragon skeleton gone and, in its place, a spirit of a black dragon itself looking at (y/n).

The dragon is looking at (y/n) with great interest, seeing that its power now flows through him, which it reminded the person who helped heal it but despite trying it met its end and rewarded the man with its blessing of its capabilities through its blood.

The black dragon bows to the young boy, knowing full well he's the last of the descendants of the man himself.

Then, roars and then turn to energy and enter the armor.

Feeling the power increase even more from the armor, which then felt his body gain even more power.

Knowing it must he the true blessing of the dragon and join in the armor to help to fight.

Then, the armor disappeared, and he's back to normal with his clothing, and in front of him was a crimson red and black crystal with a dragon design into it.

Once, he caught it and felt the power from it and made a determined look.

Y/N: I promise I won't let you down great black dragon bahamut. Said with a determined look.

The crystal shines a light, meaning it accepts.

Then he leaves the temple and knows he can't return home since everything is destroyed, so he decides to grab whatever he can and change his clothes and leaves.

He looks at his home one last time and then leaves for his journey.

A few hours later.

Warslan aircraft arrived and checked the village, seeing it was a massacre.

Judal harvey Claire's older brother is looking around with a sad expression, knowing this was something he did not expect at all, and his little sister was worried for them.

Then he sees Claire rushing of to where (y/n)'s home is.

Judal: Claire, wait. Said with a concern look.

He and some slayers went with him to find her, and by the looks of it, she's shocked to see (y/n)'s home destroyed nothing but rubble.

And seeing the body of (y/n)'s father there.

Her concern for her best friend/crush quickly to check, but her brother holds her back.

Judal: Claire, please calm down. Said with a concern look.

She ignored him and tried to free from his grip.

Then, two slayers came by towards them.

Slayer 1: Sir, we searched the entire village. There are no life signs, and none have survived. Said with a sad look.

This made judal sad to hear that, and Claire started to cry.

Slayer 2: Although there was something odd, from the mountain, there were remains of savages but turned to dust, nothing worth taking at all. Said with a curious look.

This got judal's attention knowing that the mountain is something sacred there.

Judal: Anything else in there?. said with a questionable look.

They shook their heads, which he sighed as he held Claire while she cried.

Then another Slayer came by.

Slayer 3: Sir, we did a body count, and a total of four hundred and ninety-nine are counted. Said with a sad look.

This git Claire's full attention and looks at the Slayer.

Claire: What you say?. said with a surprise look.

Slayer: Total cound four hundred and ninety nine dead miss Claire. Said with a sad look.

This Claire is surprised because this village population is five hundred.

If one is missing, meaning that (y/n) must be the one who survived.

Claire: Have you searched anywhere in the village to the mountain pass?. said with a concern look.

Again, shake his head.

This made Claire sad but can't seem to give up on him knowing he must have escaped.

While judal ordered the Slayer to place the villagers a proper burial, which they all went to do so.

Claire looked at the sky as the sun began to rise as she made a determined look.

Claire: Please be safe (y/n), I will become strong to fight by your side, knowing you do the same too. Said with a determined look.

Seven months later.

In a small city everyone enjoys their time.

By the cafe, someone who's wearing a black jacket with a hood over his head, black pants and gray sport shoes drinking tea and eating a snack.

Which then hears something from the news and looks at the TV.

News reporter: Once again the invaders strike a city but something unexpected happened there a strange red energy strike the savages and disappeared without a trace, everyone is wondering what is that coming from and the people want to thank whoever did that. Said from the TV.

The person smiled at this as he raised his head up to reveal his (y/n).

For the last seven months after the destruction of his home village, he decided to train to master his hundred bahamut, knowing it is difficult.

Especially the dragon blood within him, his parents told him that it was hard to handle because of the instincts to fight.

But he will overcome it and be strong enough to destroy all savages.

Then suddenly someone seated in front of him.

???: So enjoying what you did to save the city. Said.

He looks at the person as a young woman with long red hair and yellow eyes, as well as a buxom figure.

This made (y/n) surprised who she is.

Y/N: Vitaly Tynyanov. Said with a surprise look.

This made her smile a bit.

Vitaly: Well, that cares the introduction right (y/n) ryushin. Said with a smile.

This made him tense a bit as she raised her hand.

Vitaly: Don't worry, I'm not here to bring you harm, I have been following you for the last four months since you saved a cruise ship from a category five storm. Said with a smile.

This got his attention thinking about how she knew about that.

Vitaly: I was on that cruise ship kid, and I can say you have a very powerful hundred at your disposal, my guess is something to do with the dragon that dragon that was in that sacred temple. Said with a smile.

This made him narrow his eyes.

Y/N: How did you know about that? "said with a serious look.

Vitaly: Let's just say I'm a researcher and a scientist to help with the war against the savages. Said with a smile.

Then she points at his right hand.

Vitaly: You're having a bit of trouble with that hundred, especially your dragon blood. Said with an interest look.

This made him frown, knowing she's right about that, and couldn't find a way to overcome it yet.

Vitaly: I can help you if you allow me. Said with a small smile.

This gained his attention hearing what she said.

Y/N: Aren't you working for warslan?. said with a curious look.

She nodded.

Vitaly: True, but I have my own work cut out and always to see the remains of the savages, but the main problem is you didn't leave any remains just ashes. Said with a smile.

This made him understand because his power is something far surpasses everything else.

Vitaly: Listen, I know you can handle it, but if you let me help you, with my research on studying that and help you get stronger. Said with a smile.

This made him narrow his eyes.

Y/N: If I do that, what's in it for you to do this? "said with a serious look.

She giggled, seeing he's smart.

Vitaly: I'll give you props for being on guard kid, but I want to help your potential and help save the world, truthfully I'm not interested in fame or any other like those greedy fools think. Said with a smile.

This got him surprised at this as she raised her right hand towards him for a handshake.

Vitaly: So what do you think, do we have a deal. Said with a smile.

He thought long and hard for this, knowing it is a good opportunity to get stronger and better his skills to the limit.

So he looks at her with a determined look and shakes her hand, making her smile.

Y/N: Hope you won't disappoint. Said with a smirk.

This made her smirk as well.

Vitaly: Never. Said with a smirk.

Now, the two of them left the cafe after paying for the tea and snack and disappeared within the crowd as the journey of the dragon began.
