A/N: Uh, hello readers, St. Shade here. This is my first fic, so I decided to do something a little crossover between two shows I'm currently hooked on: RWBY and Gundam Build Fighters. If you are not familiar, go watch them.

Expect lots of mistakes and OOC.

RWBY and Gundam Build Fighters belong to their respective owners.

Gundam Build Fighters JR- Episode 1, Part 1 (Jaune and Ruby)

Xiao Long's Gunpla and Models, San Francisco, CA

"He's not here, Cardin."

"Whaddya mean he's not- I mean, what do you mean he's not here, Mrs. Xiao Long?"

Cardin, the big bully with an even bigger ego, was facing off against a rather svelte but intimidating woman whose nametag read: "Hello, my name is Raven." It was taking Cardin all of his might not to break in front of her.

"Jaune said he had to go buy something at Anchorage a few minutes ago. He won't be back for a while."

"... alright." Cardin tried smiling 'politely'. " I'll, uh… just-"

"And unless you want to actually buy anything, you'll leave. Now."

Cardin reluctantly trundled out the door, then tried peeking through the displays. Raven's steely gaze immediately caught him, and he quickly scrambled away. After a few quiet minutes, she rapped her knuckles on the desk.

"He's gone, Jaune. You can come out now." Raven's tone softened a couple of smidges.

Slowly, the desk cabinet creaked open. Jaune Xiao Long slowly crawled out from underneath it, clutching a half-finished Proto-Clanche and a pair of tweezers. His hair and clothes were a bit ruffled from hiding under the desk.

"Phew… Thanks, mom."

"Mm-hm. Jaune, I need you to take care of the store for me; I have to go get groceries for tonight's dinner."

The blonde instantly perked up."Are we having mash and steak?"

"Vegetable stir fry, actually."

Jaune blanched. "Wha!..."

"I thought you said that was your favorite dish."

"Just… please leave out the mushrooms. Please?"

"I'll consider it. Take care of the customers!"

'What customers?' Jaune thought as he watched his mom leave. 'We're nowhere near the commercial areas in San Francisco. We're not even in Japan! Which would be cool if we did.

Why did Dad have to put the store here?!'

Sutro Tower

"Wowwww…."

Ruby sat on the railing, gazing at the San Francisco skyline. 'Mom was right,' she thought, 'this world is pretty peaceful. No Grimm attacks, no burning trees, just… normalcy. Smell could take some getting used to, but-'

"Hey! Get down from there!" Her thoughts were interrupted when a maintenance worker arrived. His arms were wildly flailing. "It's dangerous up here!"

"Wha- okay! Sorry!" Ruby yelped, hopping off the tower. The poor worker lost his head screaming for a few seconds before running towards the supposed crash zone. However, the body was never found.

Union Square

It had been a somewhat mixed day for Jaune. Only a couple of people had stopped by the shop that day, and none of them bought a single model kit. They were mostly outside admiring Jaune's well-crafted models. And then Cardin showed up, forcing him into a Gunpla battle in front of the customers. As a result, Jaune's Proto-Clanche, the one he spent the whole afternoon building, was destroyed by Cardin's Tallgeese II. Cardin then had the sheer gall to not only insult him for his lack of piloting skills, but also asking him to partner up for the upcoming Gunpla World Battle Championship.

On the plus side, Jaune finally had finished up his pièce de résistance: The Gundam Age-2 Calibur. As the name suggested, the Gunpla was, for the most part, a recolored version of the original Gundam Age-2 Normal, with most of the white portions recolored into a nice, shiny gold.

He had also added in golden armor parts on the chest and joints to give a more knight-like motif. To further add to it, Jaune had also converted it's Hyper DODS Rifle into a Hyper DODS Sword Gun , with an attachment allowing the Calibur to hold a much larger shield compared to the Age-2 Normal's, ahem, buckler. He was planning to test it out here in Union Square, should Cardin show up at the store again with reinforcements.

There was only one problem. Jaune, for all of his skills in building gunpla, had mediocre piloting skills at best. If Jaune was going to have a chance of making it to the GWBC, he would need a partner that was good at fighting. That was his older sister Yang's forte. And Yang herself had decided to retire from Gunpla Battle to focus on college… and other things.

Which left Cardin as the only person interested in partnering with him.

'No,' Jaune thought, ' Like hell I'm letting him partner with me. He's skilled, I'll give him that, but he always treats my Gunpla like trash. But who-'

A tug on his shoulder interrupted his thoughts.

"Excuse me!"

Jaune turned around. Behind him was a small girl wearing a light gray shirt, black leggings, and large red hoodie, slurping on a carton of strawberry milk. Her dark hair was tipped with crimson, and her eyes were hidden by an old pair of aviator sunglasses. The girl was pointing to a nearby screen, which was in the middle of broadcasting this week's Gunpla Battle.

"Those robots on the screen… what exactly are they?"

Jaune froze in shock. "You don't know what Gunpla is?" The girl shrugged, and Jaune's face grew even more deadpan.

"You don't. know. what Gunpla is."

"Uhh.. what IS gunpla?" she replied, looking a bit worried.

"How do I put this… Gunpla are essentially plastic robot kits that you can create and customize. Most people like to do battle with them, and others-"

"So basically, it's kind of like having your own awesome robot?"

"Pretty much."

Jaune couldn't actually see the girl's eyes, but they seemed to light up behind her shades. After a few tense moments, she spoke. Or rather, sqeed.

"Omigosh That sounds SO COOL! Canyoupleaseteachmepleasepleaspleasiwannahave

myowncoolrobotandandandand-"

Jaune's troubles would have to wait. There was someone in front of him who needed to be enlightened about the joys of Gunpla Battle.

"Alright!" Jaune said. "There's a place nearby we can play Gunpla Battle. Let's go!"

As the boy turned, he remembered that he hadn't caught the girl's name.

"By the way, what's your name?"

"Ruby. Ruby Rose," replied Ruby.

"Well, uh… nice to meet you, Ruby Rose."
