I don't own RWBY just my oc

Ozpin was sitting in his office drinking his coffee as he looked at the two people in front of him, his longtime friend Qrow and a young Faunus boy the twin brother of Ruby Rose.

The young boy had declined his offer to join Beacon choosing to stay at Signal as well with his dad while his twin sister had accepted his offer.

The young boy made his weapon completely similar to Qrow's minus the shotgun feature, and the color scheme of Crescent Rose, though he names it Crescent Moon.

Glynda was standing next to Ozpin as she keeps her eyes on him studying the young boy, she couldn't understand why her old drunk friend could teach his niece and nephew to wield one of the most dangerous weapons to men kind.

"Well, you see he got kicked out of Signal for a series of fights which had started after some time that Ruby had started attending Beacon and I was hoping you'll have him attend school here as well as assigned him to Team RWBY," Qrow said as he takes a drink from his flask.

"Well I would like to have him in my school but assigning him to a team full of girls could bring problems but if you wish for him to be placed on Team RWBY then he will be," Ozpin said.

Glynda just stayed silent, she knew that putting the boy on a team with his sisters could keep him from starting fights which could mean the team will be getting a slight name change then it occurred to her that the room only suits four in terms of sleeping arrangements.

"Well the idea of putting him in Team RWBY is a good idea but it has occurred to me that the room might be a bit small." Glynda voice her thoughts.

"We simply place them in a larger dorm room," Qrow said.

Shadow Rose just watch the conversation.

"We don't have a larger room, all dorm rooms are built the same," Ozpin stated while Glynda nods her head in agreement.

So they decided that he will share a room with them then Team RWBY was called up to Ozpin office.

Qrow was then suddenly tackled to the ground by Yang and Ruby as they hug him.

He pulled them off then stood up then help his nieces up when they notice Shadow, they quickly went to hug him but was stopped he pulled out his weapon and point it at them.

"Come on shads don't be like that with your twin and older sister," Yang said as he gives her a glare clearly saying no death hugs but they still hug him anyway.

Yang and Ruby introduced him to Weiss and Blake.

"Shadow Rose will he be joining Team RWBY as well be living with you girls," Glynda told them.

'Just hope he can survive from being around four hormonal girls.' were the thoughts of the older Huntsmen and Huntress.

"So Team RWBY will be Team RWBYS?" Weiss asked.

'He may look like a male Ruby but I get the feeling he doesn't act like her and why is he a Faunus.' Blake thought as she'd study her new teammate.

"Yes Weiss, your team will be known as Team RWBYS, the same name just with an S added to it," Ozpin stated.

"Also I request you give him some female uniforms, his Semblance is called gender shift," Qrow said.

Qrow took his leave thinking his job is done and the four girls decided to show their new team member where he will be living then came the problem of where he will be sleeping since there are only four beds.

Yang then suggested that he should just share a bed with Ruby like they always had since the day they were born which brought protest from the only boy in the group.

"Come on Shadow there no problem with you sharing a bed with your twin sister," Ruby said.

Deciding not to be bothered by this and not to upset his sisters he just agreed to share a bed with his twin and gone straight to bed.

The next day they showed him around Beacon, showing him where his classes will be, then they showed where his locker is where he will have to keep his weapon in.

Sometime in the afternoon, they had run in with Cardin who shoved Ruby into the wall of the school hallway as he walks past them.

Shadow didn't like seeing his twin sister treatment from the taller boy, using his speed he was in front of Cardin then he kicks his feet making him fall than before he hit the floor Shadow quickly kneed him in the stomach sending him into the wall.

Weiss help Ruby back onto her feet as they saw what her twin brother has done.

He brought Cardin to eye level as held him by his tie, Cardin looked into Shadow silver eyes and fear ran down his spine from the look of those eyes.

Those eyes of his were so dark, unlike his twin sister who eyes always had a cheerful shine to them.

"If I ever see bullying my sister, I will cut off your head then feed your body to a bunch of starving Grimm. Got it." He said coldly to him.

Once he was let go he quickly ran for his life now knowing not to mess with him or his team.

"Was threatening him really necessary?" Blake asked him.

"I know Cardin is a bully but wasn't that a bit much," Weiss said.

"It had to be done." He simply says, "He lucky that I didn't have Crescent Moon."

They just continue their day, they went to Simple Wok for lunch.

They later looked around the shopping district when it was getting late they decided to get back to Beacon.
