I only own my OC.

Over the next few days, Yin revealed himself to be a skilled and competent fighter. Able to fight off all four members of Team RWBY at the same time with his dual katanas.

"Hey, what's your semblance anyway Yin?"

Yang asked, jumping onto his back after they finished their sparring match. Yin coming out victorious by waiting out the duration of his sister's 'tantrum' as he called it before running in and shoulder checking her into the wall behind her.

"If you need to know my semblance, then you'll know. Okay? But even Nebula can tell you I don't use it often."

Yang sighed.

"But, please….big brother…."

Yin completely ignored her, walking off with her on his back. He'd grown incredibly accustomed to ignoring whining. A trait he learned from his mother. And from helping her deal with the bandits.

"Yang, I will lock you in a room with Ruby after giving her 13 cookies. You will not enjoy it. And I am not telling you what my semblance is. Nebula has seen me use it once. You should hope you never see me use it at all."

Yang sighed, still riding on her brother's back as he walked to the cafeteria. Walking in, he saw Cardin, as usual, pulling on Velvet's ears. Deciding to step in and help, he walked over to Cardin and grabbed his wrist, pinching down on a pressure point and watching the boy squirm.

"You will apologize to Velvet and you and your pathetic excuse for a team will get out and never bother her again, or I will become very angry. You wouldn't like me when I'm angry. I can be so….so much worse than Yang."

Cardin shivered, he'd been on the receiving end of Yang's anger, and it hadn't been a good experience. He wasn't keen on experiencing what the whole school knew was her older twin brother. So, he squirmed out of Yin's grip, shouted an apology to Velvet, and ran off. The rest of his team following him. Velvet hugged Yin tightly and he smiled.

"It was nothing Velvet."

Yin said, his lilac eyes remaining completely calm while Yang climbed off his back.

"Yeah! Actually, why don't you come sit with us? Just in case team CDNL comes back."

Velvet nodded and went to sit with the Team RWBY and team JNPR. Yin sitting across from her with his sisters to his left and right, with Weiss on the other side of Ruby and Blake on the other side of Yang.

They'd just started talking about an assignment when Yin's scroll rang.

"Sorry about that, I think that's mother."

He said before answering, not really all that surprised when Raven's face showed up on the screen.

"Good afternoon Mother. You look tired. What's happened?"

Raven shook her head.

"Training new recruits, getting the ones who've been with us for a while to become somewhat competent. It's a never ending cycle."

Yin chuckled.

"So you're tired because I'm not there to do my half of the work."

Raven glared at her son somewhat half heartedly through the screen.

"You have no idea how exhausting this is. Plus all the paperwork. It's impossible for me to be two places at once and I'm trying to make the time to go to the Vytal festival this year."

Yin chuckled, he'd already called to tell her he and his twin sister were chosen to compete in the doubles match that year. And he was trying to get his sister to depend less on her semblance. Which was apparently a very steep learning curve for her.

"We'll make sure to save you a seat Mom. Then again, you could just fly in and sit with Weiss. Or Blake. I don't think anybody would really want to bother a Schnee, even if there is a bird sitting next to her."

Weiss shrugged and Raven, still maintaining her facade.

"I'll call again when I have some time. Someone's about to detonate a real hand grenade in the training field."

She said, just as they heard a loud explosion on Raven's end.

"The joys of foresight."

They heard her mumble before she hung up. Yang blinked.

"Mom can see into the future?"

Yin shrugged.

"To an extent. That's part of why she left. She knew that within two years after she did, Ruby would be born. She just didn't know to who or exactly when. She only gets bits and pieces."

Yang blinked.

"Mom has the coolest semblance ever."

Yin laughed.

"It is pretty cool."

He said calmly before going back to talking with his new found friends. It was on their way to Professor Oobleck's class that not only did Weiss' scroll start to ring, but Yin's began to ring as well. Opening it, they were surprised to see a call coming in from Professor Ozpin.

"Mr. Branwen, Ms. Schnee, would you two please come to my office. And be aware that we do have guests in Mr. Jacques Schnee and Ms. Winter Schnee."

Yin looked at his scroll.

"Why am I being called for sir? I have no known relation to the Schnee family. At all. Past Weiss of course, and even then, only as a friend."

Weiss nodded. Ozpin looked up, obviously at the Schnees, and spoke.

"You will see upon your arrival."

Yin glanced at Weiss and nodded, hanging up as the two walked towards Ozpin's office.

"Alright, what could he possibly want with us. Me in particular. I'm not a Schnee."

Weiss shrugged. For once, even she didn't know what her father wanted. But when the two entered the room. Yin immediately adopted a colder, more business oriented front. Having been his mother's right hand man, this was something he was rather accustomed to. Expose no weakness of your own, find all the weaknesses of your opponent. Regardless if it was in the arena or in a meeting.

"Mr. Schnee, Lieutenant Schnee. Professor Ozpin."

He said, feigning a vast disdain and nonchalance towards everyone in the room. Ozpin was surprised at just how different Yin was acting compared to how his sister would've reacted to the same incident.

"Father, sister. Professor."

Weiss greeted with a small curtsy. A smile had found its way onto Ozpin's face as Jacques looked the boy over and Winter silently glared at the boy. Deciding he looked far to similar to Qrow for her liking.

"The fact that you let this hooligan attend such a prestigious academy shows that this is not the safe haven you claim it to be Ozpin."

Jacques sneered. Weiss glanced at Yin, who said nothing. Winter scoffed.

"He doesn't even have anything to say for himself."

That was when Yin responded.

"Unlike my Uncle, Lieutenant Schnee, I have something known as manners. I was taught to be a gentleman. However, if you'd like to see those go out the window and for me to beat you into a bright white goo on the bottom of my shoes, than I can do that too. Though I think we can both agree blood stains terribly. Especially on white clothing."

Winter looked like she wanted to skin the boy, who had a smug look on his face, and even Weiss was trying not to laugh.

"You little insignificant brat!"

Winter roared. Yin smiled calmly.

"Takes one to know one, don't you think?"

That was the day Jacques and Weiss had never been expecting. Considering Winter launched herself out of her seat towards Yin, who rolled easily onto his back and kicked up, his shoes digging into her stomach and launching her into the wall behind him with enough force to knock her unconscious.

"I do believe this conversation is over. Now, if you don't mind sirs, I have a class I must be attending."

He said, turning to face the door.

"And please do tell Lieutenant Schnee that should she like to meet me in combat, I would be more than happy to fight her when she is in the proper state of mind."

He said before dismissing himself. Jacques looked at Weiss, who seemed just as surprised as he himself was. Both at Winter's outburst and at how Yin dealt with the outburst.

"Is he always so calm?"

Jacques asked, genuinely shocked. Weiss nodded.

"For the most part Father, yes. That's the closest I've ever seen him get to angry. Though he is a rather good fighter. To the point that we don't even know what his semblance is because he's never resorted to using it in a fight."

Jacques glanced at Ozpin, who had been silent throughout the exchange.

"Do you know that boy's semblance?"

Ozpin shook his head.

"No actually, though I have a strange feeling Lieutenant Schnee soon will."
