Whelp, we've reached the part that's usually the hardest part to write; the revelation that they're visitors from another universe. This is my first time writing this, so go easy on me alright?

It was late on the afternoon as team RWBY were riding up the elevator to Ozpin's office. Accompanying them was Dante.

"So, are you going to tell us the whole business on these people from alternate realities?" Weiss asked Dante.

"I'm not really good at describing this type of thing, I called someone to help explain it to you guys. Ozpin and Glynda already got the gist."

"Who?" Blake questioned.

"Eh, a guy that helped me deal with this type of thing before."

"Alright, but why are we headed to Ozpin's office?" Yang asked.

"Please, enough with the questions. Even I don't know why. Oz just wanted me to call you guys up there for some reason. Ragna, Jin and Noel are already up there"

Team RWBY was silent for the rest of the trip up to Ozpin's lab. While Weiss and Blake were still optimistic on the theory of alternate worlds, Ruby and Yang thought that it was awesome. The elevator doors dinged and began to open. Finally. Dante thought. He then stepped out, but regretted being relaxed as he took in his surroundings and realised things would become more complicated.

"Ah, Dante, good to see you could join us." Ozpin said as he took a sip from his cup of coffee. "You did say that your friends would be able to explain this, correct?"

Ragna, Jin and Noel were all present, alongside a group of new people. One was a tall, black-haired man that was a little older than Ragna leaning against a giant rectangular sword. He was in conversation with a teenager that bore a resemblance to Ragna, but had brown hair and had two green eyes instead of Ragna's heterochromia. Alongside them was a girl with red hair in a white military outfit, hugging the life out of Jin (whose face was starting to change into the same color as his outfit), a girl resembling a squirrel faunus hugging Noel, and a girl with blue hair in a pony tail talking to Ragna. Ragna saw Dante and flashed him a thumbs-up.

Dante took his eyes away from the visitors and looked at Ozpin. "Hm? Oh yeah. He'll call when he's ready."

"Good to know. Now, I can guess you can assess the situation right now?"

Dante looked at the group of otherworldly visitors. "Yeah, pretty much."

Team RWBY all had different expressions with the visitors. Ruby was open-mouthed and drooling at all of the weapons. Weiss noticed that many of them were dressed professionally and acted dignified. Blake was indifferent, though she displayed interest at Makoto. And Yang simply waved. Then man leaning against the sword got off of it and walked up next to Ozpin's desk.

"Well, I suppose introductions are in order. Team RWBY, Dante, this man is Kagura Mutsuki" he said gesturing to the man next to him.

"Nice to meet all of you." Kagura said. "Glad to see none of Ragna's influence rubbed off."

"The hell does that mean?" Ragna asked.

"The kid with brown hair, is Naoto Kurogane." Kagura stated, ignoring Ragna. "The one hugging Jin is Tsubaki, the one hugging Noel is Makoto and the one talking to Ragna is Mai."

"So, we can assume that you're from another universe?" Weiss asked.

Kagura nodded, "Yes, if any of you have questions, we will try to answer them as best as we ca-"

"WHATDOYOURWEAPONSDO?!"

Kagura looked startled before regaining his composure. "Uh, maybe later after we get things sorted out."

"Well, I guess I could show mine." Naoto said walking up.

Ruby was almost failing to breathe as she couldn't wait to see Naoto's weapon.

"Well, I don't have one. I fight with my fists."

Ruby looked disappointed, but then Naoto cracked a smile.

"But, I can do THIS!"

Naoto raised his arm, and a pure red longsword solidified into his open hand.

"Whoa! That's so coooool!" Ruby said as she immediately sped over and touched the blade on it's flat end. "What's it made of?"

"My blood."

"EEP!" Ruby immediately drew her hand away from the sword as if was made of fire.

"Anyways," Ozpin said, reminding everyone they were in his office. "I believe it is time for some explanations. Dante?"

Dante moved over to Ozpin's monitor and typed for a few seconds. He then swivelled it around so everyone could see, at the same time taking out his scroll and dialling a few numbers. After a few more seconds, he hooked up his scroll to the monitor, which projected the video feed from his scroll.

"Just a few more tweaks, and there." Dante said as the monitor projected a video chat. A hologram of a man with short black and white hair wearing a red and black outfit materialised. The group noted there was also a scar on the upper left of his forehead.

"Everyone, this here is Reiji Arisu of Shinra." Dante said, introducing him.

"Thank you Dante, it's good to see you again." Reiji said.

"So, can you explain to our otherworldly visitors as well as the people here what exactly you do?"

"Very well. As Dante said, i'm Reiji Arisu of Shinra. We're a group of special soldiers that dead with inter-dimensional threats."

"And you can explain our situation?" Weiss asked.

"Yes. Let me explain. Several years ago, there were several events where worlds were merging. Shinra was dispatched to stop it, but not alone. We gained allies from other worlds, but at the same time; enemies."

"This is very interesting, but, why do we need to know this?" Kagura questioned.

"Well, when the worlds merged, it seemed to send the right people we needed to help stop the merging. After that, we managed to seal off the rifts, however, the rifts seem to have a conscious of their own. If a new rift appears, then that means there's a new threat, and it sends people to help."

"So, what your saying is, it's not a coincidence that my brother ended up here." Jin deduced.

"Exactly. Don't worry, if the threat has passed, the rifts reopen a way back to your world. So in other words, it's best for you to all get comfortable here. The event can last up to a week or even several years."

"Alright, Glynda, make arrangements for our guests please, and make sure their accommodations are comfortable, just like Reiji said." Ozpin ordered before taking a sip from his coffee."

Glynda nodded and immediately left the room.

"Team RWBY, you may explain what happened to any of your friends, this is too big to keep to yourselves. And I doubt your team leader would be able to keep this to herself even if this was a secret."

Ruby made a nervous laugh before leaving with her team.

"If you don't mind," Kagura added, "I think everyone here needs to get accommodated. Is a tour possible?"

"I'll have team RWBY show you around Beacon tomorrow." Ozpin answered.

"That's great. I guess i'll show myself and the others out."

Kagura left alongside everyone else, leaving Dante alone with Ozpin and Reiji.

"They seem like a strong group. Good deal." Reiji noted.

"Yeah, I suppose." Dante said. "Also Reiji, why isn't Xiaomu here? I though she and you could never be separated."

Reiji blushed. "That's um, because Xiaomu's taking leave for a little while because...she's..."

"What, it's only been a few months from the last event and you already knocked her up?"

"Dante!"

"Just kidding man, congrats."

As Kagura walked down the halls of Beacon Academy alongside everyone else and taking a marvel at the new world they were in, two brothers lagged behind.

"Brother, are you sure you're fine?" Jin asked, concerned.

"I'm fine Jin."

"You didn't look it after the last battle."

Ragna remembered what had happened after the hordes of grimm were stopped and Glynda blocked the breach. As soon as the last one was gone, Ragna fell over, convulsing and vomiting blood. When he made it into the medical bay, he had lost enough blood that you could fill several soda bottles. Luckily, thanks to his healing factor, losing blood was not the problem. The problem was that everyone was worried about him.

"Brother, I can guess that you can now use the full power of the Azure, but your body can't take it. I think you sho-"

"Yeah I know Jin, use it sparingly."

Jin simply smiled. "You know brother, I always find times like this more relaxing. Also, like you said before you disappeared, I should try to get along with Noel. We've made...progress. This may sound childish, but...do you think that we could actually spend time as a family again?"

Ragna said nothing for a while, before patting his little brother on the head. "You really have grown up from that annoying little brat that was scared of the moon."

"Heh, I guess I learned it from you."

"So, that's what happened to that brute." Rachel said, staring into her tea.

"In other words madam Rachel, are you planning to see him again?" Valkenhayn asked, standing near her, ready at a moment's notice.

"Inevitably." Rachel said, before she took a sip. "I wonder if has learned any manners after our last meeting."

"If so, that wouldn't be the Ragna that everyone here is acquainted with." Valkenhayn said as he poured her more tea.

Ruby lay on her bed, thinking about what had happened. Her team were all conversing about the otherworldly visitors below, while Ruby retreated to her bed.

A threat? Why would there be a threat? I mean, Remnant's had Grimm attacks, but then they would have shown up a long time ago. So why now? Is it going to be something big? She thought as she turned her head and looked at her teammates. Eventually, sleep came over Ruby's mind and she slowly began to close her eyes.

Well, whatever it is...I hope my team and I will be ready for it...

Eventually, the rest of her team also retreated to their beds for the night. All of them, with the otherworldly visitors still fresh in their minds, drifted off to sleep. Little did they know, that this was only the beginning, of what was to come.

END OF ACT I

A/N: And there you have it folks, the end of the first part of my first fanfic. I suppose this was pretty cringe-worthy, but it was my first fanfic, so be gentle with the reviews.

For those of you that don't know who Reiji and Xiaomu are, they're OC's made for Namco X Capcom, and they reappeared in the sequels, Project X Zone and Project X Zone 2 respectively. I'd recommend these games to anyone who's a fan of crossovers.

One thing, this isn't done, next up is the preview chapter, which is sorta like a trailer for Red Conquest Act II.

Anyway, i'm going to take a break from this, and start my second fanfic, and all I can say is, be prepared for one hell of a crossover.
