Chapter 2: A Dragon Comes to Beacon

(Eight Years Later)

Over the years, Ddraig had trained Ruby into becoming the next Red Dragon Empress. To say that the training was hard was calling a cat mean. Even with her ever-changing body, Ruby felt like she was going through a meat grinder just to meet the Heavenly Dragon's standards. He did say that without any of the supernatural present in Remnant it gave Ruby much more train on than the previous hosts ever could. This included, but not limited to, senjutsu since dragons are living forces of nature, dragon magic of lightning and fire, and combat lessons from the previous hosts. At the same time, Ruby attended Signal Academy to start her steps into becoming a Huntress. Due to her new body that was slowly becoming a dragon's and her training from Ddraig, Ruby had to hide her new abilities and hold back to avoid suspicion. Even in another world, Ddraig was paranoid that the supernatural was present and still upheld the belief that Albion will be coming for him. It is also part of the reason why he trained Ruby so ruthlessly since he did not want to waste this chance without anyone capable of sensory skills to find out about her as the new holder of the Boosted Gear.

While at Signal it gave Ruby a chance to forge her own weapons, which Ddraig took an interest in. Combined with magic and knowledge from previous hosts, Ruby fashioned three weapons unlike anything in Remnant will ever match. The first two were twin scythes, Crescent Rose and Moon Dragon. They followed the standard of being able to mecha-shift between a gun and a melee weapon. Crescent Rose, colored red and black, shifted into a high-caliber sniper rifle while Moon Dragon, colored a deep indigo blue, changed into an automatic rifle. However, Ruby also added a secret 'ingredient' to her babies by adding magic into the blades, giving Crescent Rose the ability to produce ice magic and Moon Dragon to unleash an inferno of blue flames.

But her last weapon is Ruby's greatest creation. A double-edged, two-handed sword with an ebony hilt, golden guard and pommel, and a glowing yellow gem between the hilt and blade that Ruby created solely with magic and her own scales. What made this weapon special was because it, according to Ddraig, was a new Holy Sword. When Ddraig freshly replaced Ruby's heart, he had sealed off a magic power that Ruby already held dormant that had an extremely powerful holy aura. There was no way for Ruby to master this power since it came from Remnant and magic as she knew it was a complete myth. So she did the next best thing and put this holy magic into steel, but it would leave Ruby with emerald eyes forever.

That was a small price to pay for the masterpiece that Ruby forged that could was worthy of being called a true Holy Sword. They discovered it was very effective with killing Grimm as with just one small cut completely obliterates them. Thus Ruby named it Anduril, the Flame of the West, and etched a writing in dragon tongue on the blade that read, "The Sword that Dawns the Reign of a New King." Ddraig was quite proud of his partner for the new weapon that will serve her greatly, and they decided to seal it in the Boosted Gear itself for emergencies.

As of now, Ruby Rose, bordering on the age of sixteen, was in a dust shop looking up weapon magazines to look for ways to improve the quality of Crescent Rose and Moon Dragon. Due to her dragon genetics still changing her, Ruby was growing far more than an average human her age should. Ruby stood almost as tall as her older sister at 5'7" and and due for another growth spurt later in the year. A white body suit made to hide her growing scales reached to the middle of her neck under a black leather top built for combat evident by the crimson paddings on her shoulders, sides, and upper chest. Yet it did nothing to hide her impressive curves and hourglass figure that included her DDD-cup breasts and mid-wide hips. Around her hip was a red belt with a white rose as a buckle. Mile-long legs were covered in tight black pants with red stripes and ended with black boots. On her arms were crimson bracers with a symbol of a dragon on the forearms and flaming roses on the ones passed the elbow. A red cloak, clipped to her shoulders by two white crosses, served as a reminder of Ruby's mother as her last gift. Her face was stripped of all baby fat, giving it a somewhat lean structure with just slightly rounded cheeks of shining porcelain dusted pink. In contrast, green eyes with a silver pupil that gave an intimidating gaze. Black, spiky hair swept down to her mid-back where at the end it seemed to be on fire in crimson. Hidden by her red cloak was her twin scythes in their compact form for out-of-combat use.

All in all, Ruby was the personification of deadly beauty that made even her older sister jealous.

Ruby's musings were interrupted by a tap on her shoulder. She pulled off her headphones and glanced to back to see a man wearing a black suit, red tie, and and red glasses. A quick look around the shop found identical thugs currently robbing the place of its Dust led by an orange-haired man with a bowler hat and holding a cane.

[Packing more bark than bite.] Ddraig noted. [How about we play with them a little?]

'I like the sound of that.' Ruby replied, internally grinning like a predator.

"Yes?" Ruby asked in fake confusion.

"I said put your hands in the air." Demanded the thug.

Ruby had to stop herself from laughing. "Are you... robbing me?"

"YES!" Exclaimed the thug.

"Ah." Ruby chuckled darkly, her pupils turning into slits. "Adorable."

"Wha-"

The thug did not get to say anything else until the dragoness simply jabbed the thug. With her draconic strength, her weaker punches are enough to send a man flying, such as into a wall. Another arrived shortly afterward pointing a gun at her. She was a blur to the man even without her Semblance and closed the distance to smash his knee the other way by a swift kick. He grabbed his gun and started firing on the rest of the thugs to force them out of the store to effectively deal with them.

Once outside, Ruby discarded the gun since she already used the full clip and withdrew Crescent Rose and Moon Dragon to their scythe forms. Combined with her glowing eyes, Ruby made herself a very intimidating image as the thugs were shaking. Only their leader seemed unfazed, but Ruby could smell the fear from him.

"...Okay." Said the leader. "Get her."

As soon as they made their charge, Ruby went on the offensive utilizing her speed Semblance, leaving not just rose petals but also red electricity. As they were trying to look for her, Ruby struck like lightning lifting one thug with a swing and hooking him back down with enough force to break the road. The remaining two charged, but Ruby was already in motion. Moon Dragon tripped one of them and Crescent Rose slammed into the other to send him crashing into the side of a building. Ruby fired off Crescent Rose to use the recoil to go into the air and slam her knee into the last one with a loud crunch, probably one of his ribs.

"You were worth every cent, truly you were." The leader said sarcastically. "Well Red, I bet we can both say it's been an eventful evening. As much as I would like to stick around, I believe this is where we part ways."

The criminal aimed his cane at Ruby and fired a shot of explosive Dust. Ruby crossed the blades of her scythes in front of her to block the blast. Fire washed over her on impact, but the smoke cleared to reveal she was relatively fine. Perks of being half-dragon.

Ruby tracked his scent to a ladder. When the criminal reached the top, he instead found his throat in a tight hold by the very woman that somehow beat him to the top. Ruby lifted him up like he weighed nothing and held him over the edge. He shivered at her glowing eyes that reminded him so much of Cinder's stare. He, Roman Torchwick, was getting frightened by some random teenager.

In a last ditch effort, Roman aimed his cane at the store, but found that Ruby already swiped it away. Angered by his intention, Ruby slammed the cane into Roman's gut and threw him across the roof.

"I... don't suppose... you could... give me... that back." Roman groaned in agony.

"Bitch move." Ruby snarled before taking the cane, snapping it in two, and crushing it into smaller bits.

Roman paled at the sight of his favorite weapon broken in front of his eyes. Before he could die trying to avenge his cane, a Bullhead arrived and Roman grudgedly went aboard. Ruby frowned at the growing situation before Ddraig suddenly contacted her.

[Partner, the pilot in the aircraft has magic.] Ddraig informed.

'WHAT?!' Ruby was just able to contain her scream to her thoughts, but it did not stop her eyes widening to the size of dinner plates.

"End of the line, Red." Torchwick shouted as he threw a grenade primed to explode.

Ruby was ready to send it right back until her senses caught the approach of a new person at the last second. The grenade exploded in midair, temporarily blinding Ruby for a moment. When the smoke cleared, it revealed to the demi-dragon a woman with blonde hair and green eyes wearing the exact image of 'strict teacher' complete with a riding crop. Ruby thought it was a hidden BDSM fetish the woman had.

Ruby scowled that someone else was taking her fight away, but she pushed her pride aside to help. She sheathed Moon Dragon away and used Crescent Rose and its high-piercing rounds to target key points of the aircraft. First at the engines to make them smoke and hamper the aircraft's climb then moving on to shoot whoever was in the cockpit. She didn't have to wait long as Torchwick switched places with the person that held the very magical signature.

With her dragon eyes, Ruby could fully see the petite woman that stood in the cargo hold. The petite woman had ashen black hair, fair skin, and bright amber eyes that glowed in the dark. She wore a red min-dress glowing with yellow markings and wore black glass high-heels.

The Huntress and the magic user engaged in combat, with the latter launching a fireball. Ruby switched to Moon Dragon and fired volley at the magic user to give the Huntress a chance to get passed her defenses. Though the fire magic that Ruby saw was not really impressive.

'This magic user is nothing but a firecracker compared to my fire magic.' Ruby commented.

Ddraig added. [I am inclined to agree, but this the first magic we have sensed in a long while. But the blonde woman is quite impressive. If she actually used real magic, she would make an impressive sorceress.]

Ruby aimed back at the engines, and the bullets of Moon Dragon successfully penetrated the already beaten hull. The right engine exploded as the fuel was hit, but Torchwick and the magic user made a quick escape as the magic user sent a wall of fire to distract the duo. If Ruby was alone, she would've actually consumed the flames and retorted with a roar, but she didn't want to draw suspicion with a Huntress here.

Speaking of, Ruby decided to inch away from said Huntress and get away from here without any problems. She had successfully made it to the edge of the building and was prepared to use her speed Semblance to make a run for it.

"Where do you think you're going?" Said the Huntress sternly.

Of course it wouldn't be that easy. "Fuck."

(Police Station)

"You know," Ruby said, lying back in her chair with her feet propped up on the table, "you could just let me go and save us both the headache."

The identified Glynda Goodwitch ignored the teen as she paced around her. "I hope you realize that your actions tonight will not be taken lightly, young lady." Cue eye roll from the Red Dragon Empress. "You put yourself and others in danger."

"That's only half true." Ruby corrected. "I, like the generous person I am, put myself in danger for someone else's sake. Unless you're talking about the thugs that are going to have nice long stay in the hospital."

The only reaction Ruby got was a twitch of the eye. "If it were up to me, you'd be sent home with a pat on the back..." Glynda paused before slamming her riding crop on the table. "And a slap on the wrist. Do I make myself clear?"

"Well," Ruby drawled, "you have made it clear that you are very sexually frustrated."

Glynda had to take a very deep breath and not imagine a certain drunken crow instead of Ruby so she wouldn't strangle the child. But to her ire, Ruby wasn't done.

"I mean," Ruby continued, "it's not something to be ashamed about. Everyone has their fetish. You just have to find someone whose M to your S and can take the slaps from that crop of yours. Hell, even I dabble a bit in BDSM. Already got a nice collection to make it fun in the bed."

Glynda at this point was intensely breathing, trying her hardest to not throw the table and crush Ruby under it. She could practically see the Branwen in her. Take away the red tips and give her red eyes and Ruby would be an almost perfect copy of Raven. It was hard enough not to think she was Qrow's daughter.

"You just had to be his daughter." Hissed Glynda.

"And I'm a proud Branwen." Ruby claimed.

Ah yes, she remembered when Ozpin received the call that Ruby found out that Qrow was in fact her real father. It was three years ago when the STRQ family was just getting used to the fact that Ruby was going to have massive growth spurts and was growing her hair out. That was when shes stumbled on a picture of Raven and noted how eerily similar she was to the woman. Even Yang went catatonic realizing the way Ruby's hair reminded the blonde so much of Raven and thought she was Raven for a moment.

The girl had also proven too intelligent to dismiss it as a coincidence and had confronted Taiyang about it. Needless to say, Qrow took Ruby away for a very long discussion that revealed some truths and a story of a broken man who lost the love of his life and unable to look at his own daughter to be reminded of his failure.

What none of them knew was that Ddraig found out how Qrow's scent matched that of Ruby. The picture of Raven was just the perfect excuse to get the truth out.

His thoughts of rejection and hate were pushed aside when Ruby accepted Qrow graciously and instead almost hugged him to death. Glynda will admit that day did wonders for the man. He did not drink as often and became world famous as he took his career as a Huntsman with greater energy. It was like he was back to his prime and Summer had never died. As the years went by, Qrow's new bonding with his daughter made him a greater Huntsman and a man that did not look like he had the world on his shoulders.

Taiyang was a bit heartbroken, but Ruby assured her that he didn't think of the man any less for taking care of her. As for Yang, well, despite discovering they were cousins did not stop from referring Ruby as her sister. It was the most heart warming thing Glynda ever heard, but of course there were some things that she wished Ruby did not pick up as she saw now.

Glynda decided to take Ruby's words to heart and let someone else handle this. "There is someone here who would like to meet you."

Glynda stepped out of the way for a tall man with grey hair wearing a green suit to walk through. Ruby definitely knew the man as Ozpin, Headmaster of Beacon. In his left hand was a steaming hot mug of coffee and his right was... a plate stacked with T-bone steaks.

Once Ruby saw the hot pieces of freshly cooked meat, her stomach growled like an angry dragon. Ruby had to hide her grimace. Her new dragon body demanded a much higher appetite and an exclusive craving for meat that basically made her a carnivore. Fortunately, it is also because of her dragon biology that will never allow her to get fat. But on days she has her growth spurts, Taiyang and Qrow both had to pitch S-class missions just to have enough money to get enough food and make the local butcher a happy man.

Back to the present, Ruby idly noted that Ozpin's scent was the most bizarre she had ever sensed. It was like he was the combination of so many people all wrapped into one soul. Even Ddraig noted that Ozpin's soul felt like a Sacred Gear as he could tell it was chained to a host that wasn't the original. Not to mention the faint, but notable magical signature that matched the one magic user from earlier had.

"Ruby Rose." Said Ozpin, leaning closer to see Ruby's eyes. "You... have emerald eyes. I was led to believe they were silver, like your mother's."

"Yeah, totally not feeling like I'm going to get violated." Ruby responded, making Ozpin pull back a bit flustered.

"My apologies." Excused Ozpin, gesturing to Glynda to show a video footage of Ruby absolutely demolishing the criminals. "Where did you learn to do this?"

His only answer was a look only the Branwen twins could give. The 'figure it out yourself, genius' look. Perhaps Glynda had a point that Qrow had too much influence on his daughter.

Ozpin sighed. "Was it at Signal Academy?"

"Yeah, but they changed the name to 'Shit Sherlock,' first name 'No.'" Ruby replied sarcastically.

Glynda growled. "Would it pain you to show a little respect?"

"Sorry." Ruby apologized obviously fake. "But if there's one thing Dad and I agree on is to never be 'buddy-buddy' with authoritative figures. Prime example is James 'Ironheart'."

Ozpin chose to move along on the conversation. "They taught you how to wield one of the most deadly weapons in the world?"

"I believe we both know who taught me." Ruby answered dryly. "But the dual-wielding is all me."

Ozpin nodded and handed the plate of steaks to Ruby. She snatched one like a raptor, dangling it in front of her before biting down, pulling all of the meat at once, and chowing it down before repeating the process again. In the span of five seconds, Ruby had already gone through three steaks and not a single mess made on her face or the table.

'Ah, if only he brought a jar of honey.'Thought Ruby, holding a steak over her head before chomping down on it.

"After seeing your skill with the scythe, you're definitely Qrow's daughter." Ozpin said, taking a seat in the chair in front of Ruby. "Even before your father's tutelage, you were still regarded as a prodigy in Signal, excelling all of your classes, and even breaking records. So with such credentials, what are you aiming to be?"

Ruby stopped herself mid-bite at the question. To Ozpin's hidden surprise, Ruby adopted a serious look as she returned the steak to the plate.

"I want to follow what my mother was and succeed where my aunt failed to be." Answered Ruby sagely.

"A Huntress." Ozpin identified.

"A protector." Ruby corrected. "But I suppose they are the same in your eyes, so yes."

"Wouldn't you have done the same as a police officer?" Ozpin inquired.

"And be stuck in one place where I could be needed elsewhere." Ruby replied. "Hell no!"

Ozpin smiled at Ruby's response. "Do you know who I am?"

Ruby rolled her eyes. "Who hasn't heard of the illustrious Headmaster Ozpin of Beacon Academy? Besides, Dad doesn't stop talking about. Says that he trusts you the most out of anyone. Well, second to me."

"Would like to come to my school?" Ozpin offered. "Talent such as yours shouldn't be held back."

For the first time since being stuck in the room, Ruby smiled. "It would be my honor."

"Dammit." Glynda cursed.

"Oh cry me a river, Mistress Glynda." Ruby said.

[You do realize his intention is to get your loyalty] Ddraig warned. [This man needs you for something.]

'I know.' Ruby replied internally and took another steak to devour. 'I will play along. Besides, someone has to get my cousin out of trouble.'

(Time-Skip; Airship to Beacon)

"Aww, I can't believe my baby sister is coming to Beacon with me. This is the best day ever."

The exclamation of happiness came from a blonde standing at 5'8" with a mane of hair that reached her waist. She had lavender eyes and an hourglass figure including D-cup breasts. She wore a skirt, brown shoes, yellow braces that turned into gauntlets, a brown jacket that reached her midrift, and an orange scarf tied around her neck.

This was Yang Xiao Long, who was currently trying to glomp her cousin in a hug. Emphasis on tried since Ruby was holding her back at arm's reach.

"Yang, could you please stop?" Ruby asked dryly.

"Nope!" Yang replied. "It is my job as the older sister to hug you."

Ruby sighed. "How many times have I told you? We are cousins."

"So?" Yang replied incredulously. "How should that make us anything less than siblings? Admit it, you like me as an older sister."

"Yes, I do." Ruby admitted.

"I'm so proud of you." Yang squealed, giving up on the hug. "Everyone at Beacon is gonna think you're the bee's knees."

"'Bee's knees.'" Ruby deadpanned. "That is just so incredibly lame."

Ruby and Yang switched their attention to the holo-screen that showed a news report of the same criminal that Ruby almost bagged. "...The robbery was led by the nefarious Roman Torchwick, who continues to evade authorities."

"Might be easier to punch a hole through his chest." Growled Ruby. She was still bitter that the criminal got away. If Glynda hadn't interfered she would've used the Boosted Gear or even her magic to get rid of him and the magic user.

Yang, Taiyang, and Qrow were informed about Ruby's clash with the criminals, with the latter congratulating while the blondes berated her. When she heard Ruby say that, Yang shivered in slight fear. Her cousin's temper could surpass her own wrath.

The news turned back to a reporter named Lisa, who detailed the latest Faunus civil rights protest that turned dark when the White Fang. Any further news about the event was cut off when a hologram of Glynda Goodwitch appeared.

"Hello and welcome to Beacon." Glynda greeted.

"Who's that?" Yang wondered.

"I am Glynda Goodwitch." Continued the Huntress, earning an "oh" from Yang. "You are among the privileged few who have been selected to attend this prestigious academy. Our time is experiencing an incredible time of peace-"

'Doubt it.'Ruby thought.

[Indeed.] Ddraig agreed. [No matter what, there will always be conflict. Just be fortunate that your world isn't as bad as mine.]

Ruby clenched her fists in sheer wrath of that thought. From what Ddraig could tell her about humans from Earth, Ruby could almost say the Grimm were a blessing. If humanity were to go on without restriction they would end up poisoning the very world that birthed. As a senjutsu user, Ruby treated the world and its gifts with respect. To even think people would openly burn the world for their own selfish greed made her livid.

Pollution, deforestation, and extinction were common place with only the few knowing of the consequence. It's part of the reason she wanted to be the guardian of Remnant. If it was possible for Ddraig to come over here then it couldn't be limited to other beings from Earth. And she'd be damned to let them poison Remnant next.

"Look," Called Yang, snapping Ruby out of her thoughts, "you can see Signal from here."

"Seems forever that we were just little kids playing hero." Ruby said with a smile, her green eyes roaming over the land. "I'm... gonna miss Patch."

"Don't worry, sis." Yang chirped, bringing Ruby into a hug. "Beacon's our home now."

"Yang..." Ruby said, eyeing a blonde boy in white armor that couldn't hold it in his stomach, "Vomit Boy at six o' clock."

"Gross, gross, gross, gross, gross."

"Oi, don't get him closer to me."

"He's gonna get it on my shoe!"

"Then don't walk towards me!"

"BLEGH!"

"MY SHOES!"

"GET THE FUCK AWAY FROM ME!"

BAM!

The one termed "Vomit Boy" was sent flying across the airship courtesy of a punch from Ruby when he got too close. Unfortunately, or fortunately if you're Ruby, that sent bits of vomit all over the ship, but thankfully away from the cousins.

[Glad that one isn't my partner.] Ddraig noted.

In the DxD universe, a brown-haired pervert sneezed, which alerted the girls in the locker room that he was spying on. What came next was his wails of pain as he was the focus of womanly justice.

Second chapter done. Could've done it later, but I have a family wedding to get to. As you can see, Ruby is a whole lot more different, and better in my opinion. Her twin scythes and the fighting style is based off of Sister Friede from Dark Souls 3. The new sword that Ruby stores in the Boosted Gear is her silver eyes molded into steel to make a holy sword. Anduril basically looks like a cross of Dawnbreaker from Skyrim and the Anduril from Lord of the Rings.

If I have to give Ruby a rank where she stand in power, I would give her Mid-Ultimate-class mostly due to her dragon body and Ddraig training her with the past wielders. She can use Balance Breaker successfully, but that's where her limit is currently. That still makes her the most powerful being in Remnant because what I have seen from the Maidens I can only put them at High-class.

I quite like this kind of crossover and may do another one where she instead has a different Longinus. Maybe a subspecies of Canis Lykaon so she can all the blades that she can dream of. (Basically a god version of Unlimited Blade Works.)

Next is Chapter 3: Initiation
