Everything related to the RWBY web series is owned by Rooster Teeth, the same for the Darkstalkers (Vampire Savior in Japan) videogames saga Ghost´s & Goblins / Gargorie´s Quest / Demon´s Crest and thus other sagas like Power Stone, Viewtiful Joe, Devil May Cry, God Hand, Resident Evil (Bio Hazard in Japan) and Street Fighter are owned by CAPCOM respectively.

In case the above has confused more than one of the fic approach. I clarify from now that this crossover is more focused on RWBY and Darkstalkers, so the other sagas and possibly also sagas of video games like Castlevania and Shin Megami Tensei, that you are because of their similarity to Darkstalkers for the use of the theme of demonology and mythology . They will only be simple aggregates for the purposes of history, or in that case occasional cameos.

Without further ado let's start.

Chapter 1:

Ruby Rose the Succubus

On a dark night in the city of Vale, a group of men dressed in black suits with red glasses are led by an orange-haired man with a black bowler hat and an elegant white jacket with black gloves carrying a cane. They head to a store while the leader calmly says.

- Alright guys, let's start

They raid the store and among the men in black point their guns at the old salesman, who very scared begs - Please, take all the money you want

- No, no sir. We do not come for your money - Persuade the man with the black bowler hat, who then pointing to the glass on the glass shelf - We want all the dust he has, if it is not too much trouble

The thugs begin to take glasses from several shelves, and connect some capsules to some powder dispensing machines to steal the entire contents. That everything went well in the robbery, until one of the thugs is surrounded by a shadow that completely covers it. In which a female voice interrogates him in a seductive tone.

- Excuse me handsome, you might know what are you doing?

The man in a black suit turns around and looks in front of him at a girl with his arms crossed that is taller than him, about 1.93 meters and short black hair with a light red tone almost pink in the strands. Outstanding and beautiful gray eyes accompanied by a bright snow-like skin, which wears a set of black and red clothes starting with its black turtle neck with the collar of a rose that is attached to a red cape that next to the neck of turtle make highlight its bulky Cup D breasts, which in the hands you get to appreciate fine dark red nails. She wears a black mini skirt with red edges and on the left hip waist she wears the button of a metallic red rose, she wears black pantyhose next to boots of the same color with a long red heel. That together with the great beauty of the lady, gives the feeling of being a model of adolescent fashion magazine.

The criminal who immediately blushed at the great beauty of the girl next to not taking his eyes off his busts. That reacts awkwardly in taking out what appears to be a red Japanese katana, which in a somewhat awkward way yells at the young woman - This - This is an assault! No, no, don't-move!

The gray-eyed girl sketches a slight smile putting her right hand on her right cheek - Oh, an assault ... Do you know what happens to children when they misbehave? True? - Slowly close your eyes as your smile grows longer and longer.

- Do not threaten me! Or I cut his neck! - It is positioned with the red katana with rudeness.

The girl with her right hand grabs the red katana from her edge, and with a single squeeze she breaks the saber into small pieces - Tell me, were you going to cut someone with this trinket? - Slightly open your eyes watching as the man falls sitting on the floor and recoils very scared, while she with her long smile in a shadowed look - It seems that someone needs a good scolding

From outside the store, one of the windows breaks at the moment that a man is pulled with great force, until he finishes hitting a lamppost. That in front of the window comes the silver-eyed girl looking very confident, who humorously hints loudly

- These bad kids need a good lesson

The man with the black bowler hat when he saw how one of his henchmen ended up unconscious, whatever that girl had done to him, immediately pointed it out with his coarse giving the following order - Shoot him!

A shower of bullets comes out of the machine guns of the men in black suits. That the girl keeping her smile and standing still without apparently doing anything, with an impressive speed, grabs all the bullets with her bare hands without fail. That at the end of the shooting, squeeze with both hands the bullets captured with dust - I'm sorry, but they can't harm me with poor quality weapons

The thugs were speechless at what the girl did. The same with leader that annoying, reacting in order - What do you expect! Keep shooting!

Suddenly the girl's red cape comes off in turning into several red bats, which then the same young woman extends her right hand to her side. In which such bats come together to transform themselves into a sharp red sickle with a sophisticated technological aspect. That at the moment of starting another shooting, the girl moves her sickle in making a circle that blocks all the bullets without any effort - Oh come on. They need something better than that - After finishing the shots, the girl throws her sickle horizontally. So he cuts in half the machine guns of the malefactors and returns to the hand of his carrier as if it were a boomerang - Now it's my turn - From his back come long dark red bat wings, which moving to a super Speed is put on the side of each criminal in sight with precise gentle strokes on each necks. With falling unconscious, and the girl at the end looks to the side - Only one is missing

With the man with the black bowler hat, he finds himself running as high as he can on the top of the roof of one of the buildings in the city with the view aside ... Until he unwittingly ends up crashing into a couple of ... Soft busts.

- Where are you going? Pervert - Said the girl surprising the criminal taking a leap of fright, and falls sitting on his back.

- How did you get here so fast ?! - I exclaim the very disturbed thug, who immediately gets up and points with his cane shooting an explosive projectile that the girl receives directly to the face - That happens to you playing heroin ... What the hell!

- Does that cane shoot firecrackers? What an interesting weapon - When the smoke dissipates, the young woman is seen totally intact from the explosion with a look of mock amazement, then she gets her arms crossed outlining a small smile - Let's make a deal. Either you surrender to the authorities, or we continue playing cat and mouse

The criminal begins to lash out with a gun in consecutive shots - Die bitch! Die!

Before the eyes of the girl, he sees in slow motion the speed at which the projectiles go in such a way that each one grabs them with his hand, while he walks towards where the thug of the black bowler hat is ... Until he ends up running out of ammunition , which begins to sweat cold with the girl in front of him who sees him with a frown - With that mouth you kiss your mother? I think a good time in prison will make you modulate your vocabulary

"Hey, tell me beautiful lady, how much do you want?" I can give you millions in cash, countless dusts and even a whole line of branded clothing that makes it stand out from how beautiful it is - I beg the subject with a nervous smile while backing away - I am a man of many influences. I can offer you everything you want if you let me free

- Sorry. But I refuse to sell myself to someone like you - With a simple swipe he throws the criminal far away until he hits a wall that leaves him very cracked, and the subject loses consciousness falling to the ground upside down - That's it, it was very easy

XXXXXXX

Inside the girl's mind a vast field of red roses is displayed, which looking towards the horizon asks with a long and very excited smile - Tell me Lilith How did I do it?

- It was a ten out of ten, seriously that you showed off by defeating those assailants - Said with great joy a peculiar girl with short violet hair with a pair of bat wings on her head and a very large pair on her back. And that in height and proportions of busts are similar, even identical to that of the girl in front. In his hands he carries a sign with the number 10 that lifts him very high - I think at this step you will become very famous

- Really Lilith ?! - Exclaims the silver-eyed girl with a sparkle on her face, sketching a long smile and looking up - I see myself inside the headlines of tomorrow's newspaper - Raises her hands in front with simulating a camera - A great heroine except Vale from the clutches of a dangerous criminal

- By the way Ruby ... Don't you feel like someone is watching us? - Said the girl with the bat wings turning her eyes to the front showing a curious look.

- Really Lilith? - The silver-eyed man looks straight ahead with a lively smile, and raises his right hand in greeting - Hello guys! It's me, Ruby Rose with you! Many of you who know me may be asking ... What is happening here? Why is this Ruby different from how I remember her? And why do you have those super powers? - He puts his hands behind his back and gives a half smile with his eyes closed - Well ... It all started a while ago

XXXXXXX

About two months ago.

In the woods, just outside the city of Vale is a girl with short lilac hair and red eyes who wears a set of pink clothes, like a light leather jacket with a striped shirt, a miniskirt and leather boots ... But that somehow shows a dull look, as if it were in deep sadness.

The reason for that ...

Flashback

- I'm going to die? - Said the lilac-haired girl almost with a look in shock, being under an extravagant dress that consists of a red leotard that at least tries to highlight her little proportioned cup A busts, in her arms she carries some species of fingerless lilac gloves They reach the elbows, has blue pantyhose that can be seen engravings of bats, finally a pair of red boots ... But the highlight is not the dress itself revealing, but the long bat wings on the back and another pair but smaller in the head.

- That's right, tell me ... Have you felt weak lately? - I ask a man wrapped in a shadow that makes it difficult to distinguish his identity. And watch the girl slowly nod to her question - That's because your body is no longer able to hold as much energy as before. You are reaching your limit

- And ... How can I do it to avoid it? I mean ... Should there be a method? - asks the bat-winged lady with a small smile expressing naivety.

The mysterious man turns on his back and in a dry way almost touching the cynicism he responds - There are two alternatives to prolong your existence indefinitely, in your case ... The first and fastest and safest, is that you become part of it again. But that would lead to you being reduced to a simple invocation or an assistant as you want to see ... The second but more delayed and risky, is that you merge with a human woman that you think is worthy of your power ... Or rather, of what's left of your power

- Merge with a human woman? Why is that risky? - The monster lady said very confused.

- Because doing that can lead to one of three possible results. The first and most inconvenient is that you succumb to the will of the human and end up being assimilated by the human as his tool. The second and the one that best suits you, whether you have control over it and use the human as a disguise. The third but that will depend on the circumstances, whether between you and the human collaborate in sharing the same body in equal parts. Whether for better or for worse, it will depend on how well you get along with the human if that happens

- And ... Between 1 to 100 What are the odds among those options?

- In your case, you are a demon of great power. I can diagnose you 60% or 70% that you take control of the human that you merge. 30% who take control of you, and 10% of the possible cooperation ... Although I am only based on average human weak will, and I completely ignore what would happen in a hypothetical case of merging with a human woman with great power and will

- I don't think it matters ... Maybe it's better to merge with a human girl, right? - Question the demon of bat wings with slight optimism.

- If that is what you want. You must be hurry, since you don't have much time left to live ...

Flashback End´s

- If I'm going to merge with a human ... How should I do it? Should it be the first one to find me? Or choose carefully? - They were the doubts of the demon girl as she continues advancing through the woods on the way to the city.

Suddenly, in the middle of the surroundings, strange black creatures similar to a wolf begin to emerge, but they have strange bone masks and are red-eyed. And these aggressive beings begin to surround the demon girl, making a circle.

- What strange evil beings? - I look at the demon in alert expression while keeping an eye on the bizarre masked wolves - Although they don't seem strong. If I fight against these things, I could shorten my life ... Maybe I have no choice

BAAAAMM!

Before the demon girl prepared to enter her true form. Suddenly someone fires what appears to be a rifle from far away, in which he hits one of the masked wolves in the head. Then another shot arises towards one of the black beasts, and then a fleeting figure appears in which it digs into the face of another black wolf, which seems to be a high-tech mechanized sickle of red pieces at the top of the blade, and a small blade next to the handle, and that in the same handle is divided by red pieces in the upper and intermediate part and in the lower one there is a pica to be used as a spear ... After having stuck the mechanical sickle in the wolf , this begins to dissolve in black smoke, and then cuts off the head of another of the black wolves that immediately dissolves.

The red silhouette is revealed to be a girl with short black hair of red hue mostly at the tip of the tufts and notorious gray eyes apart from her pale skin complexion almost like snow, wearing a red hood and her dress consists of a black dress with long sleeves, which is a red corset with black ropes on the torso and down wearing a leather waist with the button of a gray rose, which on the left side loads what appear to be rifle bullets. She wears a skirt that is connected to the dress and with her inside she wears red cloth, she wears black pantyhose and boots of the same color and red ropes, whose sole is also red like red roses.

The newly red-hooded young woman makes an agile spinning jump, with her sickle killing the last of the masked wolves. I get to clean the area of monsters, and he turns to ask the demon girl - Are you alright? They hurt you?

- I'm not well. Thank you - The lilac-haired girl nods as she carefully studies the young woman who saved her ... Although there was no absolute need for assistance - I think I found the right one

- My name is Ruby Rose, and I aspire to be a great hunter. And I have been training for a large part of my life - The young woman in the red hood named Ruby Rose appears very triumphantly.

- I'm Lilith ... Lilith Aensland - The demon named Lilith Aensland calmly said. Take a step forward looking with determination - Do you think you can do me a favor?

- A favor? Which? - Question the aspiring hunter Ruby with a question mark on her head.

- I want you to merge with me

- Merge me? As well? I do not get it? - I mutter the most confused aspirant Rose - Do you want me to do a dance by joining our fingers? (1)? Or will you pass me a tendril to put it on the opposite side (1)?

- I know, it's complicated. But I'll try - says Lilith with a nervous look. Then he puts his left fist on his torso and breathes deeply - First of all, and even if it seems incomprehensible. I am not a human

- Aren't you human? So you are a faun? - The young woman in the red hood hints.

- A faun? - The demon thought very strangely, and then a light comes out on his head - Better I show it to you - Suddenly a bright red cloak is wrapped around his body, and red bats begin to emerge flying around the mantle. That then begins to emerge the red wings on the back and on the head, and then the red cloak dissipates showing its extravagant red leotard attire - This is my true form

Young Rose upon seeing such a change, her eyes began to shine with emotion accompanied by a long smile - THAT'S GREAT! How do you do it?! How do you do it?!

- It seems that he is taking it well - The bat-winged girl thought to herself slightly surprised, and then she would be serious to explain - As you can see. I am a demon, more specifically a succubus

- A Succubus? And you say be a demon? - Ruby said confused while arguing - How strange, you do not look like those horrible monsters that in movies, video games and cartoons that go out to terrorize and kill people ... Rather you look like a super hero who goes on televisión

- But ... I am in a serious situation, and my life is at great risk - says Lilith with a very acted drama, in wanting to express heroism.

- A serious risk ?! Are you in danger of dying ?! - Young Rose shouted very shocked.

- That's right - The succubus turns its back looking down, which in a very acted seriousness explains - Lately I was feeling very weak, and it's because my power reached its limit. And I am no longer able to fight for justice because of that ... And soon it disappears without leaving anything of me

- But! Should you somehow fix it ?! I mean, in the stories of heroes the good guys always find a miraculous solution to their situation - the young red hood hints very worried.

- Yes, there is a solution to my condition. And I need to merge with a human girl as soon as possible - The demon responds by looking up, and then turns to the young Rose with a lot of conviction - And you Ruby Rose! You are that miraculous solution that I need so much!

- I? - Ruby points to herself with her eyes open and nervously comments - I don't think it's the one ... I mean, I'm not even a huntress ... I'm just an amateur and I don't stand out at all

- You're wrong Ruby! I see in you a great potential talent! And I know it in the way you defeated those evil beings on your own - Insists the succubus showing his very determined right fist - More important. I seek to merge with a human girl of great heart, goodness, will and with a strong sense of justice. And I know that you have all those qualities

Ruby, hearing such moving words, begins to imagine herself as the hunter she longs to be. In being seen with respect and admiration, that for a few seconds in his fantasy world he steps back on reality and asks the succubus - I understand Lilith. But one thing, and if I merge with you, what will happen to me?

At the question, the succubus turns totally white with wide eyes. And then he turns on his back with his arms crossed, plus a nervous look - It's true, it's going to happen to her and me if we merge. And besides that there are those three odds ... Think Lilith! Think! - Begins to smile when another light comes on and turns in front of the aspiring red hood, who in an animated way hints at her - Many great things will happen! First and foremost you will have a significant improvement in your physical abilities. So you will be stronger, faster and more resistant to the degree that explosions or common weapons will harm you ... But most importantly you will have super powers!

- SUPERPOWERS! Which?! Which?! - The young woman shouts while jumping.

- Your strength, speed and endurance will rise to unimaginable levels. You will have the ability to fly through the air, throw lightning through the eyes and hands, use telepathy and telekinesia, be able to talk to animals, eternal youth and instant regeneration. And the most important is the ability to transform into other girls, and transform parts of your body into weapons - He explained in detail the succubus Aensland very sure of herself, while mentally breathing in relief - At least I didn't tell her to steal the souls of living beings, suck their lives and hypnotize men. Surely it would scare her

- SERIOUSLY THAT I CAN DO EVERYTHING IF I FUSION ?! - Ruby exclaims with stars in her eyes - Let's merge now!

- It's okay Ruby, not only would you save my life. But I will help you to have a better life - Affirms the demon girl with a sure smile as she approaches the aspiring hunter - I want you to close your eyes - See how he obeys his order, and then puts his hands on the head of the Young - I warn that this can hurt

Seconds pass and the demon girl begins to concentrate what remains of her vital energy, while a strong wind begins to form that turns slightly where both girls stand. And Lilith begins to generate several electric sparks around her body, which soon comes out that red mantle that shines very brightly while the red bats shine. That such an aura of energy becomes stronger as the fusion proceeds, and the same succubus along with the young Rose are completely covered, that after a minute ...

FLAAAASSSHHH!

There is a great explosion of blinding white light that floods the entire place, which after that there is only total silence throughout the forest.

- And during these two months I spent practicing my new powers as a succubus. And it was a very exciting experience, and thanks to me merging with Lilith, it's like I ended up looking like this - Ruby makes a very sensual pose with putting one hand on the hip and the other next to the head while winking the left eye - It's funny to think that before I looked like this - It makes a turn where its appearance changes to the Ruby that we all know - But when I became a succubus I ended up like this - Take another turn changing its appearance to what it looks like now - Now I have a model body

- And what about my Ruby ?! Yes, thanks to my body also merging with you, I change to this - Lilith does the same pose as her fused partner - Now nobody is making fun of me, telling me that I am a board or a girl playing to be an adult. I owe it to you with total honesty

- Nevertheless. My daddy had difficulties at the beginning of how I changed when I merged with you Lilith, but after showing him what I am capable of and introducing you to, change of mind - Ruby said scratching her neck a little - I want to see how Yang and Uncle Crow react as I I see now, and show you my super succubus powers

- But you didn't promise your father that you would keep it a secret? For fear of being taken as a monster - I question the succubus with violet hair with the index finger on her chin.

- Only before unknown people and my school friends. But I don't think I should hide it from my relatives, that surely my sister Yang will be impressed to see what I can do - Affirms Ruby very sure, while she wields her hands positioning them on her hips - Well, I think I have work to do

XXXXXXX

Back to reality, Ruby takes care of the unconscious thugs by tying them in ropes and the joints in front of the store, while using his Scroll to make a direct call to the authorities - That should be enough - End your call and Suddenly someone approaches him.

- Miss, what are you supposed to be doing? - I speak in a rebuke tone a blonde woman with light green glasses and eyes, who wears typical clothes of a business woman of white tones by the blouse that wears a small purple cape, whose open neckline highlights her busts. And black tones for her skirt, pantyhose and heels.

Ruby turns around and looking very confident greets her - Hello madam, did you come to ask me for an autograph of my heroic act?

- Join me right now - I order the blond woman with a frown and standing arms crossed.

XXXXXXX

Inside a dark interrogation room is the succubus hybrid sitting in a chair while that blond woman is in front with questioning her - Her actions will not be taken lightly. Are you aware that you could put others in danger?

- But I don't understand ... If I take care of those guys without even sweating - I protest Ruby raising her hands - Shouldn't you be grateful for doing the work of the law?

- I'm afraid it's much more complicated ... But there is someone who wants to meet her - Decree the serious blonde woman, who walks to the side while a door opens giving rise to an older man with white hair in brown glasses. That you saw a set of elegant dark green clothes being more prominent his green scarf, and in his right hand he loads a plate of chocolate chip cookies and on the other hand he loads a cup of hot coffee.

- Ruby Rose - The man comes to look closely at the young woman mentioned more precisely in his eyes - You have ... Silver eyes

- Eh ... Thank you sir - The young hybrid nods.

- So ... Where did you learn to do this? - Question the man next to him the blonde woman shows his Scroll with a recording of what Ruby did against the assailants.

- The ... Signal Academy - Ruby responds with a half nervous smile.

- Did they teach you to do that kind of thing? Sincerely I do not see a hunter be able to teach such feats - Said the man while watching the recording.

- Well ... I did a special training during these last months

- Special training? Hmm… That involves, making that kind of sickle through bat wings - Watch the moment in the recording of how Ruby materialized his weapon.

- That is part of my Semblance, and that was the result of my special training - Ruby gets up from the chair and detaches his cloak on several bats forming the sickle, and then takes out his demonic wings - Ta-dah! And I can even fly - Flap your wings to stay suspended in the air. Which surprises interrogators, especially the white-haired man.

- Those wings, and those bats ... It could be that she ... - Thought the man very intrigued at the revelation of the girl, who maintains his composure asks - One thing Miss Rose ... Are you a faun?

- No, no, I am not. Although these wings could say the opposite, the truth is that I do it through my Semblance - Ruby excuses nervously, that dematerialize his sickle and demonic wings in turning them his red cape.

- Interesting clarification Miss ... - The man inspects the Scroll and does a search on the internet, seeing a photo of the girl before having merged - It's funny ... But according to this photo of you three months ago. I notice that it looks very different from what you are today ... Are you really 15 years old?

- Of course yes! - Exclaimed the aforementioned a little exasperated, which is explained between silly laughter - It is that good ... I am in full growth, and it was all because I drink a lot, a lot of milk heh, heh, hey good quality milk

- Hmm ... How is it possible that you have gone from measuring 1.57 meters to 1.93 meters in such a short time? And with those body proportions you have now? - I question the very impressed blonde woman - Is that perhaps you? Have you been using drugs? Or was an operation done?

- NO! Of course not! I'm not so desperate to do that kind of thing! - Scream Ruby and hit the table, which unintentionally ends up splitting it in half. And he lowers his head very sorry for what he did - I'm sorry, I'll try to pay it I swear…. I just know, I grew up so fast that I didn't even realize

- All right, Miss - The man nods slightly while he drinks some of his coffee - As an anecdote. I remember a long time ago to meet a woman with a Semblance similar to yours

- You really met a woman with that ability ?! - Ruby questions with wide eyes.

- Well ... I couldn't say it was his Semblance speaking technically. It was rather an inappropriate skill that she could do, and even showed a combat performance similar to the one you showed a few moments ago - The man with his right hand lightly rubs his chin - The most curious of all, is that that woman did not She was human, but she wasn't a faun either… And once I asked her if she wanted to be a huntress, and I context that she didn't care about at all.

Ruby upon hearing such a thing, his eyes go blank and his jaw almost drops - he must be kidding! If being a hunstman and huntress is the coolest thing in the world. If I was someone that cool, how could he refuse something much cooler like being that? - Realizing how he acted, he lowers his eyes a little embarrassed - Is that ... Well ... Being a huntress has been my biggest dream of a lifetime

- As difficult as it may seem to you to believe Miss Rose… Although there are people with the attitudes to be a hunstman. But not everyone is really interested in practicing such a profession, no matter how skilled they are - Said the man after finishing drinking his cup - And ... So you want to be a huntress, or am I wrong?

- That's right sir! For me there is nothing better than being a hunter. I mean, being a cop is fine. But hunters and hunters are more romantic, they help people, they fight against the Grimms and many exciting things are done and Aaaaggghhh! Do you know what I mean? - I explain the succubus girl very excited, and with some difficulties to articulate some things, while the pair of adults are almost with a drop of sweat on the neck. - Apart from that I need two years to enter Beacon, the most prestigious hunter academy in the world, so much so. That even my older sister is going to enter there to be a great hunter, and I hope to be there when I graduate

- Do you know who I am? - Question the man in the green scarf with curiosity.

- You are Professor Ozpin ... The dean of Beacon - Ruby said with some calm while the aforementioned responds with greetings.

- And you want to come to my school? - Keep questioning the dean and see how young Rose nods with a small smile. Then he turns his eyes slightly in view of the blond woman who looks aside showing disinterest - Well ... You are accepted

The next day inside a gigantic transport ship named Bullhead. While the hybrid demon walks calmly through the center of the place, which within a few seconds totally attracts the attention of each man, where several remained mute and hypnotized before their beauty and it was not the few who approached with requests for courtship, and In contrast, many girls began to have great envy of the figure and rapid popularity of Ruby. That in a funny way several boys got together to the degree that they ended up fighting each other, in an effort to get the attention of the hybrid ... Shortly after the last man standing won, look with disappointment as Ruby moves away towards other part.

- Wow ... I barely give one foot and all the boys want to have me as a girlfriend - The future student of a hunter thought very surprised.

- Well Ruby ... It's normal for us the succubus to be the center of attention of men. Keep in mind that one of our greatest weapons is the inappropriate ability to seduce men - I mentally explain the succubus of violet hair showing itself as a transparent projection.

- Ok ... Only that it becomes a bit ... Uncomfortable this kind of attention - I mentally communicate the succubus hybrid with a slight nervous expression - I already told you, I'm not at all good socializing. Especially with the boys

- Neglect, you'll get used to it in the long run - Lilith nods making a thumbs up in support.

As Ruby walks, she begins to sketch a long smile - There she is! - See in the crowd a girl with long blond hair with purple eyes, white skin complexion and a height of approximately 1.73 meters, who wears an orange scarf on her neck plus a brown jacket with a high neckline that highlights her busts cup C and leaves the abdomen a little exposed, plus a pair of long black gloves and a black shorts with a brown belt, and a pair of beige boots ... Who immediately runs to greet her - Yang! Yang! It's me Ruby!

- Ruby? - The aforementioned blonde turns around and seeing the silver-eyed girl - Is it really you? - She was totally static without being able to believe who she was seeing in front - How did you grow so much?

- Heh, heh ... Well, it's a long story. And dad asked me to keep it a secret, but I'll explain it to you when we're alone - Said the succubus hybrid a little nervous with scratching the back of his neck.

- I just hope that you have not resorted to operations or strange drugs little sister - I hint very worried Yang - Thinking about it well ... Anyone seeing us together would think that you are the greatest

- Seriously? Don't consider it - The hybrid demon answered with the index finger in her mouth looking up.

- On the other hand. Are you really going to study at Beacon? And how did you get in? - I ask the older sister very curious.

- Better look at it for yourself - Point to the hybrid demon towards a large holographic screen that is showing the news. It details how the criminal known as Roman Torchwick, was arrested by a peculiar young student named Ruby Rose who is shown on the screen doing a unique pose winking his left eye with a smile. And that after stopping the criminal the same girl was praised by the dean of Beacon to be a student of the prestigious academy of hunters. That the reporter makes a lot of emphasis, in that Ruby's physique despite what appears to the naked eye. The future student is only about 15 years old, being a little young for the average age of recent income that is around 17 years old, and the same reporters joke in suggesting that in case she fails to graduate as a hunter, at least the one mentioned Ruby Rose has a future as an actress or model of magazines and fashions.

Both Yang and several applicants were stunned to see the news. Being the older sister giving Ruby a big hug - Ooohh ... I'm very proud of you! You are a heroine!

- Thank you Yang - Ruby nods with a smile as she caresses her older sister's head tenderly.

The holographic screen is immediately replaced by a hologram of that blond woman with glasses, who accompanied Beacon's dean and who interrogated Ruby in the first place - Hello everyone and welcome to Beacon, my name is Glynda Goodwich. You are among the privileged few to attend this prestigious academy. The world experiences peacetime. And you as future hunters and hunters, it is your duty to keep it ... You have demonstrated the value for this task, and now it is your turn to demonstrate wisdom and protect this world

Once the speech was over, the hologram is turned off and then several of them peeked around Ruby. That looks in amazement at what appears to be a kind of castle taken from a fairy tale, which he sees in the distance. And on the other hand you get to see the entire city of Vale below the aircraft.

- Look, from here you can see the Signal academy - I point out the very excited succubus hybrid, seeing the city and that building in the distance where they are heading - I guess we are not very far from home after all

- Beacon is our house now - Yang said slapping her younger sister on the back.

Outside the ship, there is a red-eyed black crow that is watching Ruby from the window, very suspiciously.

XXXXXXX

- Hmm ... It is debatable if it was assimilated by the human, or cooperates with her in a symbiotic relationship - The mysterious man wrapped in a shadow thought analytically while watching the hybrid succubus. In that it is within what appears to be a dreary-looking research laboratory, and that glimpses several screens illuminating the area. That among them show computer data and others show television channels - Even so ... It may be useful in the future

In one of the screens that tunes a news channel, in which a woman with blue skin is seen with a pair of long demonic horns on her head. That said demon woman is very worried - Latest news! Ladies and gentlemen ... It seems that we are in the presence of a great war throughout the Makai. Several kingdoms are preparing their troops to search for each of the 7 Power Stones that have dispersed in unknown places, after the final death of the Great Dark Lord Dracula

- Mmm? ... - The demonic man watches the televised channel, where a fairly old image of seven diamond-shaped crystals is shown on the screen, which each crystal forms one of the seven colors of the rainbow.

- It is known that during the last thousand years, Dracula was able to obtain the 7 Power Stones and with it he became so powerful to be the supreme king of the Makai and be listed as the Great Dark Lord. It is said that each of the Power Stones is capable of granting new powers to any being, and even elevating demonic powers on a large scale. That by seven o'clock the devil would become as powerful as any god and divine entity - It shows recordings of various types of demons fighting bloody battles and making all kinds of disasters - Following the thirst for power of many demons, several have been fought killings, looting and even invasions in various kingdoms. In an effort to seize one of the Power Stones, even coups are being reported to overthrow the kings and rulers

Outlining a half smile, he comments with clear normality - Very normal ... Everything is good when looking for more power

- In contrast, families of demons and several who are against all this wave of violence. They were forced to migrate to other places, being the most voted by the majority the human world. That despite not being subjected to war, it is known that the humanity of that world is going through a very complicated time of social imbalance, for issues such as ethnic inclusion and orientation, a supposed political correctness. Economic crises and a fear that a possible 3rd World War will explode - Large rows of demons are shown carrying equipment, in mobile homes and other types of transport. That at the end of them there is a large dimensional space-time portal activated - On the other hand, there seems to be an alternative to the human world, called Renmant. That it is known is another world ruled by human, but that seems more peaceful and stable - The reporter approaches a red-skinned, bearded and slightly obese ogre - Here one of the refugees who intends to go to Renmant

- I heard that in that world of humans there is no knowledge of us demons. So it will be easy to impersonate a human and try to live a normal life, away from all this madness

- As well as many. They desperately seek to avoid war, while in contrast others seek to become the next dark lords regardless of cost ... Let us pray that all this chaos will end as soon as possible. Here Makai News out ...

The mysterious man turns off the screen while looking up with a smile showing a lot of interest - So now the Power Stones are free ... This is going to get very interesting

Chapter End

Reference Notes:

1- Ruby when asked about merging with Lilith made reference to Dragon Ball. More precisely to the metamoru dance used by Goten and Trunks to form Gotenks, and later Goku and Vegeta would use it to form Gogeta .

The other is another method of fusion shown in Dragon Ball, such as the use of special tendrils named Pothala. By Goku and Vegeta to form Vegetto .

Author's Notes:

Hello everyone. I hope you enjoyed the first chapter of this fic ... That again for those who have been following me for some time, it seems strange again that I make a Fanfic crossover of RWBY and even with Darkstalkers ... Well, certainly the idea of this fic arose from certain sources.

First and foremost, I rely heavily on the end of Lilith Aensland from Darkstalkers 3 / Vampire Savior 2 where Lilith herself when she was not part of her sister Morrigan again. This disappears and dies, that being honest gave me quite pity its end.

Second, for Ruby's Fusion with Lilith rather than relying on Dragon Ball. It is more based on how it is handled in Devilman, as well as a subtle homage to the Devilman Lady Spin-off manga (renamed Devil Lady in her anime adaptation) Starring Jun Fudo (i.e. Akira Fudo rule 63) On the other hand the This Ruby Súcubo's way of acting will be more in line with the concept of the succubus. As also make it similar to Cutie Honey (Another manga made by Go Nagai creator of Devilman and Mazinger Z)

Third the final part regarding the war in the Makai (Demon World) and the Power Stones. The latter is a nod to the saga of games of the same name of Capcom (Fuck Capcom... When will you get a Power Stone 3? I've been waiting for more than 15 years) The other is a nod to another saga of Capcom games, its once a Spin-off of Ghost & Goblins known as Gargorie´s Quest. More precisely his delivery to the Super Nintendo, Demon's Crest (Play it is a GAME OF THE GODS!) It is even in debate whether to put the 7 Power Stones of the fic with the same operation as the Crest of the video game of the gargoyle Firebrand (Red Arremer in the Japanese versions)

As such, he planned to make the chapter more extensive. More than anything dedicated to how Ruby's father (Taiyang Xiao-Long) reacts to the change of his daughter, and how he is doing a training to understand his super succubus powers ... But I decided to suppress it, for feeling it quite unnecessary and irrelevant to the plot. And make the chapter more direct with what this new Ruby Rose can do (which is not that she has shown much to say)

And honestly ... I dare to say that this introductory chapter I did very on the fly. And there are certainly some ideas I have on the table, but I am in debate whether to test them or not. Either they can positively or negatively affect the fic.

Here are two ideas to consider:

That Lilith Aensland has participation ... As the double of Ruby in alternate plan. While the real Ruby fights the bad guys under the pseudonym of Sucubus Rose under her appearance with the colors of Lilith (ie violet hair and red eyes) ... Or instead that Ruby invokes Lilith in Jojo´s Bizarre Stand plan Adventure or as a family member to help you in battle for certain techniques such as the Darkness Illusion that Morrigan usually uses.

As I did with Ruby Rose, that also Weiss, Blake and Yang merge with demons (obviously female) so they can be on par with Ruby ... That for practical purposes they will be succubi based on certain internet memes related to a Super Crown. Or instead keep Ruby the only one fused with a demon, in this case a Succubus.

Anyway ... I'm open to more ideas. Except for other plans with one of the RWBY characters, more precisely Jaune Arc ... I have a special idea for him, and thus I save all requests related to him.

See you in the next chapter ... That is in the planning phase.
