AN: Hello everyone. It's Aloehisja with a new story as promised. I'm a fan of the Metal Gear series (except for that zombie survival one) and RWBY, and after reading a one shot that combined Grimm Eater and RWBY, I wanted to try and make one myself.

To make things a bit more challenging and not so predictable, no I will not just replace the Metal Gear characters with the RWBY characters. I'm also going to add some different things to keep it close to the RWBY world.

And as promised we have two perspectives: from Jaune Arc and from Ruby Rose.

Disclaimer: I do not own RWBY or Metal Gear.

Prologue: Ruby Rose

The forest of Patch was quiet as eleven-year old Ruby Rose lay in the snow atop a cliff. She was the daughter of Taiyang Xiao Long, Vale's greatest fighter of the century and Summer Rose, the White Rose. Warrior's blood flowed through her, and she was born with the will to be a Huntress.

Lately though, she had doubts of becoming one. The world was quiet as the Color Wars ended. The longest battle recorded in history, and her parents were in the books as the legendary team to push back the invaders of Atlas and Mystral along with her Uncle Qrow. After the long war, there was a treaty amongst the four kingdoms to put things to a truce. Vale and Atlas even put their past behind them to form a partnership – they were soon branded as the Inner Circle whilst parts of Mystral beyond Haven and Vacuo along with all of Menagerie were stated as the Outer Circle.

"Ruby." A thirteen-year old girl with long curly locks of gold called her with a puppy following her. It was her sister Yang Xiao Long and their dog Zwei.

Story was that Yang's mother defected to Mystral to fight against Atlas and Vale with her own army. Raven Branwen was branded a traitor to Vale for slaughtering hundreds of soldiers and was exiled from the Inner Circle. Were she to be spotted, she would be treated as a terrorist and shot on sight.

"Yang." Ruby greeted her sister as she got off the snow.

Walking towards her, the older sister brushed off the pieces of snow still stuck to her. Yang Xiao Long loved her sister more than anything in the world. While many in the town who knew her mother shunned her as 'her child,' Ruby along with their dad and uncle loved her all the same. Summer even defended her from those who thought to take their anger out on the cute blonde girl.

"It's time for lunch." Yang pulled her sister along as they headed back to their house. "What are you even doing out here? It's freezing."

"I was just thinking." Ruby said, hugging her sister's arm to keep her warmer.

"About what?"

"What if I don't want to be a Huntress?" She asked, knowing she could share anything with Yang.

Humming in thought, Yang turned back to her sister with her own question. "If you don't want to be a huntress, then what do you want to be?"

"I don't know." Ruby raised her shoulders, not thinking that far ahead. She just felt like there was more to life than being a warrior.

"Maybe you can do something that you like." Yang helped out.

"I like cookies." Ruby immediately said. "Ooh! Maybe I can be a baker! I can make cookies all day and give them to people while eating some myself."

"Maybe." Her older sister chuckled, not being a hardcore fan of sweets like her.

"Or maybe a dogsled racer." Ruby had stars in her eyes as she picked up Zwei. "And Zwei can be my leading dog."

"I'm not sure Zwei will get that big." Yang shook her head.

Their uncle once joked Zwei was part wolf that would someday get big, but the cute puppy didn't look like it was going to grow any bigger.

Putting Zwei down, Ruby continued to think of more things she liked. There was being a blacksmith because she liked to make stuff, then she thought of being a teacher like the nice lady in Signal. The future was looking bright for her and Yang. Anything was possible when you lived in the Inner Circle.

"What about you?" Ruby asked Yang. "What do you want to become?"

"Me?" Yang pointed to herself with a thoughtful look. "I still want to become a Huntress."

"Really?" The little sister raised a brow. "Why?"

The truth was, Yang wanted to prove to the world that she wasn't her mother. She wasn't a traitor to Vale and she was more than her mother's child. She wanted their respect and would prove it by becoming a protector of the people like her dad and Summer Rose.

"I just want to have fun exploring the world." She lied. "Even though the war is over, there're still Grimm lurking around every corner. If you become a baker or a dog sledder, you're going to need me around to keep you safe from the big bad Grimm. Rawr rawr rawr!"

Ruby giggled uncontrollably as Yang pulled her into a tickle fight. As they laughed and enjoyed their walk back to the house, they saw Summer sitting on the porch waiting for them with a cup of cocoa in her hands.

"There you two are." The woman in a white apron stood up. "I almost thought I'd have to come get you both."

"Sorry mom." Yang apologized, still not letting go of Ruby. "I found Ruby laying in the snow."

"Well come inside and get into some dry clothes the both of you." The mother told the two girls. "We don't want you catching a cold like the last time."

"Yes mom." Both girls said together, running in to get changed.

Before the mother walked in, she turned back to the trees after catching a bit of black in her vision. She thought she saw a crow sitting on one of the branches, but it was gone. It couldn't have been Qrow since he was on a mission. Not brushing it off as some sort of coincidence, Summer slowly shut the door to her house with a feeling of dread looming over her. Peeking from a crack in the curtain, she scanned the trees but saw no bird.

"I'm probably just imagining things." Summer thought to herself as she walked to the kitchen.

Turning on the stove, she heated up another pot of warm milk knowing his two girls would want a cup. In Yang's case she'd want to mix French vanilla in hers while Ruby would want strawberry flavor. Inhaling a breath to calm her nerves, she took a sip of her cup before it became too cold.

She nearly spat the drink out though once she saw something move to her left at the corner of her eyes. Turning, she saw the kitchen window. Walking towards it, she peeked from all corners to see if if any Grimm was around but saw nothing.

'Get a hold of yourself Summer.' The mother berated herself. 'You're safe at home with your two daughters.'

Walking back to the table, she turned off the stove before the milk overheated and poured two cups for her daughters.

"All clean." Ruby ran in with Yang close behind.

They looked so adorable with the sweaters she made for them. Any worry Summer had was washed away just having the two of them close by. Whatever came, she'd take it on and triumph for them.

"When's dad coming home?" Yang asked as she sat at her side of the table.

"He'll be back soon." She replied, knowing Taiyang was currently in town getting some errands she texted him. "I asked him to get some bread and milk on his way home."

Both girls shared a look with each other before turning back to Summer.

"Are you going on a mission?" Ruby asked, swinging her feet as she waited for her cup to cool down a bit.

"How did you two know?" She asked, knowing she hadn't told them yet.

"Whenever you're about to go on a mission, you always tell dad to get bread and milk." Yang pointed out.

Nodding, Summer guessed she had to come clean now that they knew.

"Yes, there is a mission." She told her daughters. "Tonight I'll be going to Atlas Academy to meet their Headmaster for a diplomatic meeting."

Things wee always busy for the Xiao Long – Rose couple since they became legends. Qrow was the same having to always travel from village to village. The three members of ST(R)Q were heroes and were always at the top of the list whenever they were available. It made raising their kids tough with how little time they had for them. But now that they were bigger though…

"Would you guys like to come with me?" She surprised the girls with the sudden question.

"Yes!" They both cheered, getting off their chairs to hug their mom.

Giggling in excitement, the three couldn't wait for tonight.

After lunch and helping the girls pack their extra clothes for the trip to Atlas, Summer took the time to go over her assignment one more time. She'd meet with the headmaster of Atlas, get some documents and blueprints for the reinforcement of Vale's security, and be home by the next morning. It all sounded so boring but after the battles she and her husband have been through, a change of something less bloody was what she needed.

"I'm home!" Her husband announced as he walked in.

"Dad!" His girls ran to him while dressed for their trip.

"Hey!" He smiled, picking his two precious gifts into his arms. "What's with all the excitement? I only bought bread and milk."

"We're going to see Atlas!" Ruby exclaimed, getting Taiyang to turn to his wife.

"They're getting old enough to travel now." Summer explained. "Plus we never get to spend enough time with them before another request for us pops up."

Taiyang didn't disagree with her there. It was hard to juggle between the requests and his two girls. Turning missions down was easy, but the pay to keep his girls fed and clothed paid handsomely. Just because you became a legend in the history books didn't mean you instantly got the Lien for everything. They still had to pay for the heater and some of their loans.

"Ok." He agreed, setting his girls down to give his wife a kiss. Hearing an 'eew' from behind them, he saw his two girls were watching them. "You guys are still here? Go do what little girls do. Play with a doll. Teach Zwei to go poop in the woods."

Rolling their eyes, the girls went into their rooms to play. They had enough playing in the snow for the day and it was getting dark fast. It wouldn't be long before the girls were called by Summer for their trip to Atlas.

Atlas

"Wow." Ruby whispered with eyes wide as she stared at the shining city. Despite being nighttime, the city was like a metropolis with all streets and buildings illuminated. "It's amazing."

"It's a little too bright for my taste." Yang squinted.

On the ride here, Summer was glad her two girls enjoyed themselves. They had their heads constantly on the windows looking at the view, she didn't have to worry about them running off and causing trouble for the other passengers.

"Come on girls." She grabbed their hands. "Atlas Academy awaits. We can get some souvenirs later."

While they walked the streets, Ruby saw how rich the place was and marveled at the technology all around her. Yang on the other hand was staring at something else.

"Mom. What's that over there?" The blonde pointed to a robot marching behind a person with dog-ears carrying a large sack of crystals.

Summer saw who she was pointing and immediately stopped in her tracks. She knew Atlas had questionable practices, but to see it was to this extent was horrible. Seeing his daughter waiting for an answer, she couldn't tell her what it really was.

"Don't look sweetie." She pulled the two along.

Even as she rushed them to the academy, Yang glanced back to see the faunus had fallen over with the weight of the crystals crushing him. She thought the robot would help the man up, but instead it just watched the man and waited for him to get back up.

'Why?' The twelve-year old asked as she couldn't understand the bad treatment.

As Summer turned a corner, Yang lost sight of the robot and faunus – but she wouldn't forget what she saw.

Atlas Academy

"You two wait here for me, okay?" Summer told her two girls as they stopped at a door with the title General on it.

Knocking on the door, Summer opened it to see a man with a white moustache having a shouting contest with the head of Atlas Academy and its army, James Ironwood. Seeing Summer enter, the two men ceased their argument to address the newcomer in the room.

"Miss Rose." The general greeted her with a nod. "I was just having a discussion with Jacque Schnee. You must have heard of him."

"Of course she would have. A legend such as herself would know of me." The Schnee smirked while eyeing Summer up and down. Walking towards her, he took her hand and placed a chaste kiss on it. "Charmed I'm sure."

Summer had to stop herself from gagging at his attempt to 'charm' her. His hands were cold as ice and the look in his eyes showed he was after more than just friendship. For the sake of getting those vital documents though, she'd stomach his presence.

"I'm sorry, but I've never heard of you." She said sweetly while pulling her hand away.

Turning back to James, she ignored the small frown he formed. Her chance to speak with the general was interrupted as Jacque moved to stand in front of her once more.

"Well perhaps we could get to know each other better." He said with a winning smile. "Say a dinner after this? Maybe a soiree?"

"Sounds nice, but I'd like to take my children on a tour of Atlas after this." The look on the man's face was priceless. Bad enough she and her husband have people like him trying to get into their pants, it was all so they could have the benefit of sleeping with the 'legends.'

"Pardon me." Summer bowed, walking to Ironwood's desk. "I'm here to collect the documents regarding Vale's security construction."

"Of course." James nodded, taking the papers from underneath his desk. "With the rising of the group known as the White Fang, we all need to up our securities in the Inner Circle."

"I couldn't agree more." Summer nodded, placing the papers in a safe pack. "I'll be seeing you men to your conversation now."

"Thank you." James bowed curtly as she walked out of the office. Turning to Jacque, he gave a smirk knowing how badly he failed.

Closing the door, Summer looked around to see where her daughters were waiting but found they weren't anywhere close. Groaning at their energy, she rushed off to find them. Little did she know, someone else was following her.

With Ruby and Yang

"Yang, wait up." Ruby called to her sister as she ran through the streets.

The older sister couldn't get the image of that faunus out of her head. If she was going to be a Huntress, then she needed to help people when they needed it. Slowing down a bit so Ruby could be close, the blonde girl peeked a corner where she last saw the robot and the man. Finding no one, she looked around to see they were far away from the academy.

"Let's go back." Yang turned around to her little sister.

Grabbing her sister's hand, they took in the sight once more of the shining buildings. They're mom was probably waiting for them at the same place.

"Oops! Sorry." Someone bumped into Ruby said. The sisters couldn't make out who it was due to the trenchcoat he was wearing.

"It's ok." Ruby shook her head. "Do you know how far Atlas Academy is?"

Instead of saying a word, the person just pointed them in the right direction. After that, the person sprinted far away from themwhile keeping his head covered.

"Thank you!" The little girl shouted and ran in said direction with Yang close behind.

As they made it to the entrance though, there was a large crowd of people blocking their way. Some were murmuring in whispers while the police pushed them back from crowding one spot.

Pushing their way to the front, they saw a white cloak soaking in blood. The girls knew that cloak anywhere else and pushed past the police to get to the body. The general of Atlas was present as well while summoning some med-bots to his location.

"Mom!" Both girls cried, kneeling down to their injured mother.

"G-girls." Summer croaked, feeling she was losing too much blood.

"Get those two away from here." James ordered some of his men. "the medical drones are on their way and need the room to maneuver her gently into the med bay."

Lifting up the two girls, the soldiers carried them away from the crowd to another location to be looked after. One of the soldiers comforted them that their mother would be alright while boasting of Atlas' medical advancements. They weren't listening though. They were too worried for their mother to hear anything.

Come the next morning, Summer Rose was announced dead post procedure. Atlas medical teams did all they could to treat the blood wounds and gave transfusions. News reports stated it was mutiple stab wounds that went clean through the vital organs. Theories on who the killer was flooded the net and news channels linking from the White Fang to a crazed serial killer. The documents on her body were not found, putting emphasis on the terrorist group lurking in the Inner Circle.

The children of Summer Rose were escorted back to Patch personally by General Ironwood himself, who delivered the news to a distraught Taiyang Xiao Long. Her body was buried in Patch on the very cliff where Ruby liked to lay down and think.

This was the drop of water that sprouted the Rose of the Battlefield.

END

AN: And that's another prologue. Not as chaotic as Jaune's but if you were paying attention, they are in the richer part of the world when the Color War ended. Don't be jumping to conclusion yet readers. Nothing is as it seems in this and the events aren't linking just yet. The Color Wars has ended, but there is another more silent war going on between the two: The Gray Wars. (Similar to what we have as the Cold War.)

Hope this got you hooked, because we're going down the path of M Rated with both stories.
