With a few answers from the mysterious green-haired boy, which basically amounted to: "I'm from another place, and these cats are my magical talking familiars."

Okay, so that might not have been the explanation given to her, but she kind of started to zone out when he said his cats were familiars.

Seriously?! Like that what witches have? That doesn't even make any sense to her!

Besides, she wasn't allowed to question him much more, and it seemed he finally realised he needed to keep secrets, so she didn't get much more out of him anyways.

It was when she was getting a bit short of temper, the stress of being in another world and having to fight her team-leader and not knowing where Weiss that pompous heiress that she nonetheless still thought of as a friend and…

"Argh!" The raven haired Faunus girl bashed the wall in frustration, giving out a frustrated scream.

"Are you alright Blake?" A questioning voice.

She shook her head to clear it a bit and drew a deep breath.

"I'm fine Ryusei, you don't need to worry about me." She tried to sound as collected and level as possible.

"Really? You don't seem-"Ryusei continued.

"I'm fine. You don't need to worry." Blake cut him off.

"But-"Whatever the boy wanted to say was cut off as his head was put into a lock by a strong arm.

"If Blakey says she's fine then just give up. She's stubborn about things like that." Yang said cheerfully as the poor teen was crushed into her… 'assets'.

"Ah! Yang! I got it! Let go! Can't…" The poor otaku shouted, desperately flailing to get out of the ridiculously strong grip that was slowly suffocating him.

The busty blonde let go with a slight pout.

"Why is it that everyone always wants me to let go?" She asked innocently, or as innocently as was possible with that person at least, all the while Ryusei was grasping for breath while shying away from her.

"You seriously don't know?" Blake murmured with a disbelieving expression on her face.

"Hmm? What, you say something Blake?" Yang asked, not having heard the murmur.

"Nothing, Yang, nothing." The raven haired Huntress said with an amused smile.

"All hands, prepare to sortie! Enemy contacts!" Suddenly Rio's voice rang out through the hallway from the PA system.

"Let's go." Suddenly Yang became serious.

-Break—

Yang wondered as her Gespenst left the hangar, was it really worth it for her to do this right now? Or should she be working harder to try and get home?

No. She didn't have much of a choice, right? If she wasn't working for Ingram she probably wouldn't be able to do much at all. And she did meet Blake… And-

She looked out over the water before her, behind her an island stretched out.

But what halted her thoughts wasn't the gorgeous view.

It was because, at the back of this non-standard unit of Armoured Modules, was a very non-standard Guarlion, carrying the colours, and most importantly the emblem, of her little sister Ruby.

And the buxom blonde despaired.

She couldn't fight her sister!

That was just not possible for her!

"Who are these guys?" Ryusei asked, referring to the different colour scheme of this new unit.

"They are the Treue squad, the elite guard of the UCC… what are they doing here?" Rai answered.

For a few seconds Yang wondered to herself how he knew that, but then she remembered that Rai's brother was a high-shot in the UCC, and according to what she had been able to dig up after that, so was most of his family, minus Rai himself.

As a matter of fact… if the Treue squad were the elite guard…

Then the people they would have been guarding are the members of the Branstein family. That was to say Rai's family.

Okay, so she knew Rai was kind of aristocratic and all but… That's closer to royalty than simple aristocracy! Even Weiss' family doesn't have their own personal elite guard!

Was she really so desperate to ignore that her little sister was on the other side on a battlefield?

Okay! Focus.

If Ruby comes, do your best to avoid her without hurting her…

Take down the rest and she should either retreat or surrender…

"Hey! That Guarlion! Is that… Yang's sister?" Garnet exclaimed with worry staining her voice.

"Yeah. It is." Yang gritted her teeth and forced herself to accept the situation.

"She's with the Treue squad now? Well, I guess she was with Elzam first time she showed up so…" Aya said contemplatively.

"Enough chatter! Here they come!" The stern voice of Rai snapped them into focus even as the Treue squad moved out.

Since it seemed like Ruby wasn't intending to move out yet, although that really didn't mean anything considering the speed her Guarlion could move at, Yang decided to move out and face the oncoming Lions head on.

But it didn't quite go as expected. The Treue squad wasn't the elite guard for nothing, and combined with the difficulty Yang had controlling her Gespenst on water, and it was no wonder she couldn't quite do as well as she wanted.

Her attacks missed, and she had to focus all her attention on not getting completely destroyed.

In the meanwhile, Rai had engaged one of the other Guarlions that had accompanied the unit, presumably the leaders of the unit, weaving a deadly dance of cannon fire and railgun shots with the occasional sudden charge.

This was finally interrupted when Aya launched a Ripper into the Guarlion, temporarily halting it, and giving Rai ample opportunity to land a solid hit.

While the Guarlion still flew, it seemed it wouldn't be able to fight, and soon retreated.

But by now Yang had managed to retreat far enough to stand on solid ground, and suddenly it became far easier, or at least so it felt in that one moment, for Yang to fight, something the Lion that had been harrowing her all this time found out the hard way.

Having well memorized the patterns of her opponent, and surprising the bastard with a sudden increase in ability, Yang's Gespenst's energized fist met it head on.

"Jet! Magnum!" The sunny teen shouted heatedly. "Oh! That felt nice!"

She was glad to have managed to actually hit the thing, and seeing the machine explode violently brought a gleeful smile to her face.

She looked towards the rest of the skirmish, and noted that only Ruby and the last Guarlion remained, and neither of them had joined the skirmish it seemed.

But just as she started considering moving in to help corner the two, a new contact appeared.

The first thing she noted as she looked up at it was that it was large. While not as large as the Hagane, it was taller than the Grungust. Coupled with a generally spiky design, and a blood red colouring, and she had to be honest.

That was probably the scariest looking machine she had ever laid eyes upon.

And while she might have hoped it was on their side, any chances that was the case were squashed as its pilots voice came over the open frequency.

"Warriors of the Hagane, I commend your fighting spirit. Let me and this Valsion test your mettle."

The strong, grizzly voice, a voice that had no place coming from a researcher… The powerful voice of the Supreme commander of the DC, Bian Zoldark.

"Bian Zoldark! What's he doing here!?" Once again it was Ryusei that raised his voice first.

"Commander Bian. What are you doing out here?!" An unknown female voice joined in.

"Pull back captain Hainkel. I will be the Hagane's opponent." The scientist turned commander said.

"But-"The woman called Hainkel started.

"Let's do as he says. The Valsion won't go down to them. Not as they are right now." A sweet voice interrupted.

This voice… it was Ruby's-Did Ruby just say that the Valsion would beat them…?

Yang really wanted to feel miffed about that but…

Ruby wasn't the leader of a team for nothing, and she was a weapons maniac… If she knew the capabilities of that machine, and judged that it was more than a match for them…

She might just be right…

With a disgruntled sound the captain of the Treue squad withdrew. But while Ruby distanced herself, she didn't leave the battlefield.

"What are you doing Rose? I told you to leave this to me." Bian questioned.

"And I will. But I will take the liberty of observing." Ruby answered.

And wait… she knew the man?!

Yang steeled herself.

"Ruby!" She shouted.

"Sorry sis. But you really should focus on Bian right now." That was all her sister said.

And it was only thanks to realising Ruby really meant it that she wasn't swept away as a massive torrent of energy started drawing in objects around the massive monstrosity of a machine.

She watched as the Grungust was pulled in, only for the Valsion to release a powerful wave of pure energy that sent it away again, causing heavy damage.

They quickly unleashed all their bullets at it, only to find the same type of barrier as the Granzon had mostly nullify the barrage, leaving the bullets to plink against the thick armour.

Yang resisted the urge to rush in, the fact that the bloody thing was flying over water and that it was wielding a very large sword making the normally hot-blooded gal hesitant to close in.

That, and bad memories from the Granzon.

"If you won't come closer… Then I'll just have to shoot from afar!" Bian shouted, surprisingly hot-blooded for a supposed scholar.

In response the Valsion pointed its arm towards them, energy gathering in a cannon like device on top.

"Cross Smasher!"

And with a shout the energy was released in the form of a beam with two spiralling beams around it.

Luckily they all evaded it, but its mere passing caused turbulence, and its impact as it hit the water surface caused a massive amount of water to burst out.

Then the others started unleashing as much firepower as possible, Blake unleashing the Slash Ripper, Rai hitting it with the Beam Cannons, Ryusei with his Hyper Beam Rifle, the Hagane firing its main batteries (and hitting, much to Yang's surprise).

With all these powerful ranged attacks hitting, and causing a bit of damage, next Irm closed in, having received field repairs from Garnet, who's jet had been equipped with a repair module, unleashing his sword, with Ingram simultaneously attacking with the Disk Slicer.

Seeing those two fearlessly close in, Yang felt she had to go as well, adding a Jet Magnum to the attack.

And despite all of this, they only dented the armour.

The Valsion had just taken enough punishment to sink a battleship, and it wasn't even hampered in its functions…

"You have got to be kidding!" She exclaimed.

She knew the Granzon was though, and this machine, with similar defensive equipment but more mass and armour, should be even tougher.

That didn't mean she expected it to be that durable.

"Enemy reinforcements!" Came Rio's distressed voice.

True to her words, a battalion of DC units arrived.

"Commander Bian! Please withdraw! We can't afford risking to lose you here!" A distressed soldier contacted Bian, coincidentally allowing them to hear since Bian had been talking to them.

A lot.

She didn't mind banter even mid-battle, but there should be a limit, and she was certain Bian crossed that.

"Hum, well, it seems you are not yet worthy. Very well, I will withdraw for now." The strong-featured man conceded, and the massive machine withdrew.

None of them tried to stop him, as they didn't feel confident in their ability to fight him under these odds.

It was simply a smarter move to let him go right now.

"Huh? He's what?" Suddenly it sounded like Rio was questioning someone.

And even more suddenly, the machine they had taken in previously, apparently named Cybuster, launched.

"Heh. You seem like nice guys, so I'll lend you a hand!" The green-haired boy, named Masaki exclaimed and moved to intercept the DC reinforcements.

Yang's only warning that Ruby had passed by was the familiar rose petals and a tempest that buffeted her. Then she was there, blocking the Cybuster's path.

"I had a feeling you were here, and I have been looking forward to testing my Guarlion against you. Besides, it seems you know Professor Shirakawa, so I've been a bit curious to meet you." The young Huntress said as she brandished the oversized Crescent Rose replica.

"You, you know Shu? Tell me where he is!" Masaki shouted in response.

Ruby had a feeling he was here? How…

Oh.

That ability of Ruby's, the one that almost never manifested.

Summer had also had it, as far as Yang understood, but it was stronger in Ruby.

If only she could remember what dad had called it…

Author's notes: Okay... was this, good? Meh. Also, that mission. Holy flip Bian! The first time through terrified me. The Valsion's theme, combined with the fact that the bloody thing is super though, and the fact that I did the massive mistake of having him spawn over water... I think the objective literally timed out on me. I'm sure most of you agree that the first encounter with the Valsion left an impression. I mean sure, you're fighting an elite squad... That doesn't mean you're prepared for facing an mid-point boss. Especially one you can't beat. Even a haxed out Grungust can't one shot him, so you literally can't beat him on this mission.

Okay, maybe you can, but still. Not with the units you have there normally, and especially not the first time around, since it can't be new game+, unless its OGs, but that's a remake, and I certainly haven't played it...

Ruby versus Masaki! Speedster versus speedster!

I hope you enjoyed and that you have a nice day.
